Back in 2012, I had the pleasure of visiting the IBM Watson research center. Among the people I talked with was George Tulevski, who was working on developing carbon nanotubes as a possible replacement for silicon in some critical parts of transistors. IBM likes to think about developing technology with about a 10-year time window, which puts us about halfway to when the company might expect to be making nanotube-based hardware.

So, how's it going? This week, there was a bit of a progress report published in Nature Nanotechnology (which included Tulevski as one of its authors). In it, IBM researchers describe how they're now able to put together test hardware that pushes a carbon nanotube-based processor up to 2.8GHz. It's not an especially useful processor, but the methods used for assembling it show that some (but not all) of the technology needed to commercialize nanotube-based hardware is nearly ready.

The story of putting together a carbon nanotube processor is largely one of overcoming hurdles. You wouldn't necessarily expect that; given that the nanotubes can be naturally semiconducting, they'd seem like a natural fit for existing processor technology. But it's a real challenge to get the right nanotubes in the right place and play nicely with the rest of the processor. In fact, it's a series of challenges.

Note that above I said that nanotubes can be semiconducting. Unfortunately, they can also be metallic. (Well, not entirely unfortunatelythat's quite useful for other applications.) Even more unfortunately, when we make a batch of nanotubes, we can't control whether they're going to be metallic or semiconducting. Instead, you just end up with a random mixture of the two.

There have been two approaches to dealing with this. The first is to just put more carbon nanotubes than you need into place, then identify the metallic ones and destroy them. Needless to say, this isn't especially efficient. The alternative is to take a batch of carbon nanotubes and then separate out the semiconducting ones. There are various ways of doing this, but most of them haven't been 100-percent efficient. Which of course means that, at some level, you're going to be putting a piece of metal where you wanted a semiconductor, shorting part of your processor out.

For the new work, IBM relied on a development pioneered at the National Renewable Energy Lab (a facility targeted for massive cuts by the current administration). Some bright people at NREL realized that semiconducting carbon nanotubes would preferentially interact with complicated organic solvents that have nitrogen-containing rings in their structure.

Researchers at IBM decided this would be very useful indeed, so they tested the technique out. A single extraction with the same technique and, 10,000 individual nanotubes later, they can report that over 99.9 percent of the purified tubes were semiconducting. We can consider NREL's work replicated. And, if 99.9 percent's not good enough, there's no reason that the process couldn't be repeated in order to furtherincreasethe purity.

Of course, those semiconducting nanotubes don't do a processor much good if they're still sitting in solution. Ideally, you want a method of placing them in specific locations on your chip. Here, IBM rolled its own solution. The company developed a system in which polymers would only form on specific material on its chips. These polymers would help guide carbon nanotubes out of solution and in to specific locations.

So, we've now got a basic construction kit for carbon nanotube processors. But it's still not enough to do something useful. Modern processors have a complicated mix of p- and n-type semiconductors (which tend to build up positive or negative charges). Carbon nanotubes are naturally p-type, but they can be converted to n-type if they're placed in proximity to certain metals. Unfortunately, those metals tend to oxidize under normal conditions.

So the people at IBM put a cap over this metal layer to try to protect it. Unfortunately, the metal they used (scandium) turned out to like oxygen so much that itstripped it out of another part of the hardware, a hafnium oxide layer. So, that layer had to be replaced.

With all of the hurdles cleared, the team decided to make some individual transistors. These worked extremely well, with every one of the 192 transistors the researchers tested being operational. So, the team went on to try to build actual circuitry. Not useful circuitry, but instead a typical test case for new processor technology: a ring oscillator. This is a series of gates set up so to flip bits; if the gates get a 1, they convert it to 0 and vice versa. By putting an odd number in a ring-shaped configuration, each individual gate will oscillate between 1 and 0 with a timing that depends on the amount of delay involved in each individual gate changing its state.

The good news is that they produced 55 functional ring oscillators, with a performance of up to 2.8 GHz. This is an important demonstration that the process works. Unfortunately, IBM had to build 160 ring oscillators to get the 55 functional ones. So the process isn't mature. In fact, since ring oscillators only really involve five functional gates, it's a long way off from producing anything that might be considered a product.

But, to return to the point this discussion started with, IBMand the rest of the material science communitystill have a bit of space left in their timeline to get this commercialized. And, five years ago, they were still working on getting pure semiconducting nanotubes. Given the progress since, I wouldn't rule things out.

In his ongoing search to locate his hitting stroke, Kyle Schwarber took early batting practice Saturday under the watchful eyes of hitting coach John Mallee and manager Joe Maddon.

Schwarber appeared in his third consecutive game Saturday night after being recalled from Triple-A Iowa, where he was sent to jump-start his lagging offensive production this season. In his first at-bat he lined an opposite-field single in the second inning of the Cubs game with the Pirates at Wrigley Field. He followed that with a solo home run to center field in the fourth.

"It's a continuous process," Schwarber said. "I'm really happy with how the performance from down there is transferring up here. You're back in the big leagues and you want to get ahead of things. Now that it's out of the way I just plan on being myself."

Maddon was on the field for another purpose during Schwarber's pregame hitting session and couldn't help stopping to watch and provide additional instruction.

"I just wanted to be an advocate of what's going on and lend another set of eyes to what they're doing," Maddon said. "Being an old hitting coachwhat they're doing and how they're doing it is very interesting to me."

Schwarber said he has focused on slowing down his mechanics and limiting movement.

"Everything looked really good," Maddon said. "Primarily, everything has been based about shorter movements (and) getting ready sooner."

Coming soon: Starter Kyle Hendricks (tendinitis in his right hand) checked out fine a day after his bullpen session Friday and will make a minor-league start Monday for Double-A Tennessee.

"Once we get that done and accomplished and he's well we'll be able then to try to figure out the post-All-Star break rotation stuff," Maddon said.

Minor honors: The Cubs named catcher Victor Caratini and right-hander Thomas Hatch as the organization's minor-league player and pitcher of the month for June, respectively.

Before the Cubs called him up from Triple A, Caratini hit .345 with four home runs and 21 RBIs in 25 games with Iowa.

Hatch went 3-2 with a 0.98 ERA in five June starts with Class A Myrtle Beach.

KUWAIT British Foreign Secretary Boris Johnson said on Saturday progress could be made to heal a rift between Qatar and other Arab states, although a solution was unlikely to be found immediately.

Saudi Arabia, the United Arab Emirates, Egypt, and Bahrain have cut diplomatic and transport ties with Qatar over accusations it was financing terrorism, claims which Doha says are "baseless".

"My impression is progress can be made and there is a way forward," Johnson said in a televised interview released to media after meeting senior government figures in Kuwait which is attempting to mediate between the two sides.

"But I'm not going to pretend to you now that it is necessarily overnight or this is going to be done in the next couple of days," he said.

Johnson, who held meetings on Friday with Saudi Crown Prince Mohammed bin Salman and the crown prince of Abu Dhabi, Sheikh Mohammed bin Zayed Al Nahyan, is due to travel to Qatar later on Saturday for meetings with its emir and prime minister.

"We think the blockade was unwelcome and we hope there will be a de-escalation," Johnson said.

PARIS French President Emmanuel Macron said he told Russian counterpart Vladimir Putin the two countries had made a "tangible" progress in bilateral relations, which could move to a new phase.

The two presidents met for the first time on May 29.

"On the subject of bilateral and regional issues, I welcome the quality and the intensity of the work that has been established since then," Macron, who kept Putin waiting for about 20 minutes, said ahead of their meeting behind closed doors.

"So I think now we can move on to a new phase because we both saw that we were doing what we were saying," Macron added.

HAMBURG German Chancellor Angela Merkel said on Saturday there was no glossing over the fact that there had been "very, very slow" progress in implementing the Minsk peace accords aimed at ending years of violence in eastern Ukraine.

Merkel said she would hold four-way telephone talks on next steps soon with the leaders of Russia, Ukraine and France following a more procedural conversation with French President Emmanuel Macron and Russian President Vladimir Putin on the sidelines of a G20 summit in Hamburg.

"We agreed to continue the process. But we also observed that progress had been very, very slow - with stagnation in some cases, relapses in others. We didn't gloss over the situation," she said. "We will stay in touch, we'll stick with the format. We don't have any other basis."

HAMBURG U.S. President Donald Trump hailed progress on trade after meeting his Mexican counterpart on Friday, as Mexico's government said it expected a general agreement on reworking the North America Free Trade Agreement (NAFTA) by the end of 2017.

For the first time since becoming president in January, Trump met Mexican President Enrique Pena Nieto, whose foreign minister Luis Videgaray said he expected talks on renegotiating NAFTA to start on Aug. 16., the earliest possible date.

The meeting at the Hamburg leaders' summit of the Group of 20 economies was keenly anticipated in Mexico, and officials were quick to stress talks had been productive, despite Trump repeating that Mexico would pay for his planned border wall.

"We're negotiating NAFTA and some other things with Mexico and we'll see how it all turns out, but I think that we've made very good progress," Trump said after the meeting.

In response to a shouted question from a reporter about whether he still wants Mexico to pay for the border wall, which aims to keep out illegal immigrants, Trump said, "Absolutely."

Pena Nieto, whom Trump called his "friend," said the meeting would "help us continue a very strong dialogue" on NAFTA, while his aides emphasized that they had not discussed the wall.

NAFTA underpins more than $1 trillion worth of trilateral trade between the United States, Mexico and Canada. Videgaray, who was present at the talks, told reporters afterwards it had been a "big part of the conversation" with Trump.

"We expect to have a meaningful, constructive, modernization of the agreement that is good for the three nations," the minister said. "And we think there is a lot of room to make it a better agreement for the three nations."

Speaking on Mexican radio, Videgaray also said both governments agreed the renegotiation "should be a relatively quick process" that looks to "generate agreements, at least in general terms, by the end of the year."

Disputes over migration, Trump's border wall - which Mexico has repeatedly said it will not pay for - and his claim that free trade with Mexico costs jobs in the United States, have strained relations between the two neighbors.

Trump has threatened to impose punitive tariffs on Mexican goods to protect U.S. industry, and to pull out of NAFTA altogether if he cannot rework it in the United States' favor.

However, especially since Trump stepped back from initiating the process of withdrawal in April, Mexican officials say business leaders from the NAFTA nations have increasingly coalesced around a shared desire to keep the agreement alive.

Trump reiterated his aggressive stance on NAFTA in a weekly address published by the White House online after his meeting with Pena Nieto, but apparently recorded beforehand. In it, Trump said he was pursuing a "total renegotiation" of the pact.

"And if we don't get it, we will terminate, that is, end NAFTA forever," he said in the video.

There has been uncertainty about the process because the United States has yet to set out its negotiating objectives. That is due to happen on or about July 16.

In the meantime, issues such as Trump's border wall remain sensitive. Pena Nieto's spokesman Eduardo Sanchez called in to Mexican broadcaster Radio Formula from Hamburg, stating that the two presidents did not discuss the wall.

"That subject was not part of the conversation," he said.

The two presidents also explored a possible guest worker program for migrants in the agriculture sector as well as the importance of "modernizing" NAFTA, according to a statement from Mexico's government released after the meeting.

Trump hails NAFTA progress, Mexico eyes general deal by end-2017 - Reuters

The Presidents Xi and Trump have several things in common: both entered professions in which their fathers gave them natural advantages. (Xi Jinpings father, the revolutionary hero Xi Zhongxun, helped build Chinas Communist Party; Donald Trump inherited a fortune, and a real-estate business, from his father, Fred.) Xi and Trump both perceive the world in zero-sum terms. Both dispute the notion of loyal opposition. And both favor coercion over consensus.

But, in most respects, Trump struck the Chinese leadership as an oddity, and, as soon as he became President, Chinese leaders started reading his books in search of clues to his thinking. From The Art of the Deal they concluded, among other things, that Trumps theatrical demands are only a tool of negotiation. Trumps approach, according to Cheng Li , of the Brookings Institution, who researches Chinese lite politics, was clear: You should put some of your demands outrageously high, so you will never be a loser.

The Chinese leaders reading paid off. When Trump and Xi met for the first time, at Mar-a-Lago, in May, Xi was unruffled by Trumps assertions of bravado, including his revelation, during dessert, that the United States was about to fire missiles at Syria. Xi succeeded in handling Trump. Emerging from the Citrus Summit, Trump made no mention of tariffs or trade war; he proclaimed great chemistrynot good, but great and hailed Xi as a very good man with an incredibly talented wife. Trump, like many, had looked at Xis genial half-smile and succumbed to the misreading that they were in agreement. A Chinese editor in Beijing once told me, of Xi, Hes round on the outside and square on the inside; he looks flexible, but inside he is very hard.

Xi, for his part, did not bother to reciprocate Trumps outpouring of emotion. Though Trump asserted that he would succeed in persuading Xi to choke off trade to North Korea, as a way to curb its nuclear program. (Trump tweeted, I have great confidence that China will properly deal with North Korea.) An Arab foreign minister who visited Beijing shortly after the trip told me privately that, given all of Trumps campaign talk of China raping the United States, Chinese officials were very pleased to have mollified him at his own country club.

Unsurprisingly, the one-way romance proved fragile. Last week, after Trump realized that Xi was not going to pressure Pyongyang into submission, the White House announced sanctions against Chinese entities accused of aiding North Koreas weapons programs. The Administration also announced a $1.4 billion arms sale to Taiwan, moved U.S. ships into contested waters in the South China Sea, and dusted off threats of tariffs and a trade war. In a dyspeptic phone call with Trump, Xi complained about these moves as negative factors.

Then things got worse. On July 4th, North Korean leader Kim Jong-un personally led the test-launch of the countrys first intercontinental ballistic missile. Kim defiantly crossed a de-facto red line that Trump had drawn in January, when he said that such a test wont happen. For most Presidents, the public failure of a central pillar of foreign policy would be humbling, but Trump is disconnected from the details of diplomacy, and he directed his frustration, via Twitter, toward China: So much for China working with us - but we had to give it a try!

Now the U.S. and China can, in theory, start the real work of forging a response to the Korean crisis. John Delury, a North Korea expert at Yonsei University, in Seoul, told me, Unfortunately, Xis own ties with Kim Jong-un are tenuous, and thus Beijing is of not much use in getting a read on Pyongyang or facilitating diplomacy. Trump, for his part, seems to be moving away from the notion that China can solve the North Korea problem for him, which is a mark of progress in his learning curve.

At the G-20 meeting in Hamburg this week, the worlds attention will focus largely on Trumps meeting with Vladimir Putin. But Trumps meeting with Xi will have more immediate relevance in dealing with the Korea crisis. In an op-ed published in the Washington Post on Thursday, Jake Sullivan and Victor Cha, foreign-policy advisers in the Obama and Bush Administrations, respectively, proposed a new approach to getting China invested in freezing the North Korean missile tests. Instead of threatening North Korea with cutting off trade, they propose, in effect, paying it to cut off missile tests. The basic trade would be Chinese disbursements to Pyongyang, as well as security assurances, in return for constraints on North Koreas program. . . . If North Korea cheated, China would not be receiving what it paid for. The logical thing would be for it to withhold economic benefits until compliance resumed. The Times outlined a similar idea in an editorial of its own this week.

This approach is no silver bullet, but, in the land of lousy options, as diplomats call the North Korea problem, it is as good as any, in part because it does not rest on a false understanding of the other party. The relationship between Xi and Trumpleaders of the worlds two largest economies, a rising power and an addled power, straining to coexistmay well prove to be the most consequential diplomatic liaison of its time.

It is too soon to know whether Xi and Trump could build a genuine relationship, but, until now, they have been operating on separate wavelengths, intersecting only at moments of superficial understanding. In Chinese, this is known as a chicken talking to a duck. Both sides are talking, but neither truly understands the other.

How Xi and Trump Can Make Real Progress on North Korea - The New Yorker

ZURICH Deutsche Bank (DBKGn.DE) said that it is making progress in its planned partial initial public offering (IPO) of its asset management unit, according to a recent memo to staff.

Germany's largest lender announced its plans for a partial IPO of the unit in March as part of a broader restructuring of the bank reeling from law suits and trading scandals.

Nicolas Moreau, a board member who oversees Deutsche Asset Management, said in an email to staff seen by Reuters, that Swiss regulator FINMA had approved the establishment of Deutsche Asset Management (Schweiz) AG.

The new entity incorporates the existing Swiss asset management activities formerly part of Deutsche Bank (Suisse) S.A.

"We continue to make excellent progress with our IPO preparations and achieve notable milestones in our preparations," Moreau said in the note.

John Cryan, Deutsche's CEO, has said the bank would maintain a "controlling and super-majority stake" in the business.

The sale would take place at some point over the next two years, Deutsche said at the time, and could raise 2 billion euros ($2.3 billion).

Deutsche hopes that by giving its asset management unit more operational independence the unit will be more attractive to talent.

Deutsche Asset Management has more than 700 billion euros invested worldwide.

BRISTOL It was a night of surprises as both the 2017 outstanding citizens and the new Miss Bristol Shania Dumelle never expected to be chosen as this years winners at the 48th annual Bristol Progress Days coronation banquet Friday at the Parkway Chateau.

Hearing her name called as one of the 2017 outstanding citizens came as a complete surprise to Connie Kirchner, who was also serving as the events emcee. The annual award is given to two adults and two youths for their selfless dedication, good character and work in the community.

Im speechless, said 66-year-old Kirchner, a mother of three and grandmother of five. There are so many outstanding citizens in this room.

Kirchner has been active in 4-H, is active in her church and has helped coordinate volunteers working concessions at the Bradley Center in Milwaukee. She also works for the Kenosha County Court system as a bailiff.

The second outstanding citizen, Robert LeFebve, 76, has lived in Bristol for 35 years. The father of two and grandfather of two is a former trustee of Paddock Lake, and was chairman of the Rehabilitation District and the committee to form a community library. Hes been a member of the Bristol Planning Commission for 10 years and is a charter member of the Bristol Historical Society.

I, too, love Bristol, LeFebve said. I think each and every one of us should provide service to our community. We have an excellent community willing to help each other. Thats what community is.

This years junior outstanding citizens were Logan Piktel and Ruby Loecher, both 13 and seventh-graders at Bristol Grade School. Both are members of advanced jazz band and received music contest medals for solo and ensemble competitions.

Piktel has been a drama club member for three years and was nominated for being a good kid and a good friend. Loecher is a member of the Challenge 4-H Club, Randall Optimist Club and was called the type of student well on the road to success for life by her teacher.

This years Miss Bristol, 18-year-old Shania Dumelle, called her win a complete surprise. She entered the contest to do something different. I thought maybe if I didnt do it, Id regret it.

Her goal, she said, is to be like a big sister to everybody.

Dumelle graduated from Central High School and plans to attend the University of Wisconsin-Parkside to study applied health sciences/pre-med. She wants to be a physicians assistant. Asked what one thing shed want to change in the world, she said, If I could change one thing it would be childhood hunger and thirst. No matter who you are, everyone should be nourished and well-fed.

The contest included four contestants. Other winners included:

Third runner-up: Ashley Lura, 18, who graduated from Central High School and plans to attend UW-Parkside majoring in business management and minor in art.

Second runner-up: Nina Scott, 16, a junior at Central High School who plans to follow her familys tradition and go into the Navy. She later wants to study to be a dermatologist. She sang, I Cant Help Falling in Love for the talent portion of the contest.

First runner-up and Miss Congeniality award winner: Haley Gorsuch, 18. She loves drawing and Disney, and plans to attend UW-Whitewater to study art education. She wants to be an art teacher.

AS WE SPEAK OF FINLEY PARK.....IT'S BEEN NEARLY A YEAR since a Colorado-based designer released plans to upgrade the place. But - since those changes were announced - nothing has really taken shape

Columbia, SC (WLTX) -- It's been nearly a year since a Colorado-based designer released plans to upgrade Finlay Park. But, since those plans were announced, nothing has really taken shape.

"I used to come here a lot, but now, it's just when they have the Movies in the Park," said NytashaGlenn-Bray.

Glenn-Bray said she doesn't bring her children to Finlay Park often because there are no playgrounds for them to enjoy and there's too much homelessness.

"You have some people out here, staring at kids, and I'm not too fond of that. It makes you a little paranoid," she said.

Last August, a designer from Citivas: Landscape Architecture Firm presented plans to restore the park to its former glory. The plans included a new multi-purpose building, a splash pad and rejuvenating the infamous fountain. The project would cost more than $20 million -- but one year later.

"Not much really is going on with Fnlay Park, other than we have decided that the $20 million project was too much for the park at this time," said Councilman Howard Duvall.

Councilman Duvall said the city is looking to spend $10 million on the project.

"We need to shore up the fountain and the walls. We need to make sure it's safe," he said.

Duvall said he doesn't know why the design firm has not come back with an alternate, more affordable, plan.

"I need direction. That's the simple way to put it," said Mark Johnson, the designer.

According to Johnson, he has not been contacted by the city to make a plan that will cost $10 million.

"If the mayor called me up and said, 'Show us what we can do for $10 million', we can do that, but we just haven't been given that request," said Johnson.

Johnson said it's common for them to design a plan, but the city takes a few years before they're able to prioritize the funding.

If the renovations happen, Duvall hopes it becomes a destination spot for Columbia.

"It'll be a place you can go without the concerns. It'll just live up to the dream of Kirk Finlay who envisioned that park many years ago."

Duvall said they are looking at different funding sources to come up with the $10 million.
