Chemists manage to reduce the toxicity of antimicrobial nanosilver in products
Chemists at the University of Helsinki have managed to manufacture new polymer-stabilised silver nanoparticles. The result is significant because the antimicrobial characteristics of silver are used in textiles, floor coatings and paints even though the impact on health of silver nanoparticles are not entirely known.

RUSNANO Supports Pharmaceuticals Manufacturing for Age-Related Illnesses
This project to manufacture innovative drugs combating age-related diseases is based on pioneering work by V.P. Skulachev, member of the Russian Academy of Sciences and director of the A.N. Belozersky Research Institute of Physico-Chemical Biology.
Nanoswitch changes its configuration based on surrounding pH level
Dartmouth researcher Ivan Aprahamian and his team have developed a new molecular switch that changes its configuration as a function of the pH of the environment.
Microscale thermophoresis – a hot road to new drugs
A group of Biophysicists at LMU Munich hav developed a unique technology called 'microscale thermophoresis' that allows to measure intereactions under close-to-native conditions, thus improving the decision making process in drug development.
Scientists glimpse nanobubbles on super non-stick surfaces
Scientists at the Brookhaven National Laboratory have obtained the first glimpse of miniscule air bubbles that keep water from wetting a super non-stick surface.
Study quantifies the electron transport effects of placing metal contacts onto graphene
Using large-scale supercomputer calculations, researchers have analyzed how the placement of metallic contacts on graphene changes the electron transport properties of the material as a factor of junction length, width and orientation.
Water may not run uphill, but it practically flies off new surface
University of Florida engineers have achieved what they label in a new paper a 'nearly perfect hydrophobic interface' by reproducing, on small bits of flat plastic, the shape and patterns of the minute hairs that grow on the bodies of spiders.
New material to harvest electricity from body movements
Scientists are reporting an advance toward scavenging energy from walking, breathing, and other natural body movements to power electronic devices like cell phones and heart pacemakers.
Neutrons poised to play big role in future scientific advances
Subatomic particles called neutrons are poised to play a big role in fighting HIV, slowing global warming, and improving manufacturing processes. The reason: They are the focus of a process called neutron scattering that provides unprecedented ways to study the chemistry of a wide range of important materials, including coal and biological cells.

Robots Making Your Food [Image Cache]
This sushi-making robot, along with the Okonomiyaki robot and the omelet robot, aren't new, but they are featured in this NYT story about chef robots to get you up to speed on machine-prepared cuisine.
The only question I have, since these robots are from Japan, is about where else that hand has been. [NYTimes]

How to convert PN value to ANSI flange rating/class?
I have some question about how to convert to PN value to ANSI flange rating or class as below.
1. Is it different when the material different? For example bronze, cast iron, ss or pp?
2. PN value seems to mean the flange rating, but in case the end type is screwed, then what's the meaning
Nikola’s Letterhead (And How Tesla Won the War of the Currents) [Lifechanger]
This was Nikola Tesla's letterhead. It reminded us that along with the often overlooked little things which change our lives, we need the loud, filthy, slaughter-filled battles just as much. Like the dirty War of the Currents.
Just in case you're not familiar with the War of Currents—one of my favorite messes in the history of electricity—allow me to catch you up. On one end of it all we had Nikola "Wizard of the West" Tesla, George Westinghouse, and alternating current. On the other hand was Thomas "Dirty Fighter" Edison and direct current.
The whole trouble began when the United States were ready to move away from Edison's idea of direct current and try that newfangled AC. Dear ol' Tommy couldn't just sit back and let that happen. So, he did what any man in his right mind would do and started a smear campaign against the new system:
[He spread] disinformation on fatal AC accidents, publicly killing animals, and lobbying against the use of AC in state legislatures. Edison directed his technicians, primarily Arthur Kennelly and Harold P. Brown, to preside over several AC-driven killings of animals, primarily stray cats and dogs but also unwanted cattle and horses. Acting on these directives, they were to demonstrate to the press that alternating current was more dangerous than Edison's system of direct current.
When that wasn't enough, Edison got a bit more personal:
He also tried to popularize the term for being electrocuted as being "Westinghoused". Years after DC had lost the "war of the currents," in 1902, his film crew made a movie of the electrocution with high voltage AC, supervised by Edison employees, of Topsy, a Coney Island circus elephant who had recently killed three men.
Considering that we don't refer to someone being shoved into the electric chair as a "Westinghousing," I'd say Tommy didn't do so well. Anyway, we're not here to make fun of killing animals, Tommy's lost war, or to brag about Tesla. The point is that a good idea—alternating current—wasn't taken down by a dirty fight. And that, ladies and gents, is a #lifechanger.
