Under The Microscope: UTC Honors College Student Working On Nanotechnology In Japan – The Chattanoogan

Mesenchymal stem cells.Cooper Thome is working with mesenchymal stem cells.What the heck are mesenchymal stem cells?

In regular folks terms, theyre stem cells that can grow into a variety of different cells, from bone to cartilage, from muscle to fat.

They have many therapeutic applications, from the treatment of orthopedic injuries to autoimmune diseases, Mr. Thome says. Knowing how various environments and factors affect stem cells is very important if we wish to make further advancements in the types and viability of stem-cell treatments.

Mr. Thome is a UTC Honors College student whos in Japan this summer, working an internship in nanotechnology at the National Institute of Materials Science in the city of Tsukuba. A chemical engineering major in the College of Engineering and Computer Science, he has three semesters left before graduation.

Landing the Japanese internship is a major accomplishment, and Mr. Thome is one of only six students from across the U.S., from Florida to California, who were chosen. Hell be in Japan until early August.

After hes finished with the internship in Japan, hell fly into Atlanta to attend a research convocation for the various National Nanotechnology Coordinated Infrastructure REU participants from universities in the U.S, he says.

Translation: A national conference on real-world applications for nanotechnology. REU stands for Research Experiences for Undergraduates, so its geared to college students.

In addition to the terrific research hes been pursuing in that field including an important internship last summer at Georgia Techs Institute for Electronics and Nanotechnology and now this International REU in Japan hes been an active and valued member of the Brock Scholars community in the Honors College, helping to mentor new students during our orientation retreats, leading nature hikes, and more, says Dr. Gregory ODea, associate dean of the Honors College.

Back in Japan, Mr. Thome takes tiny, tiny stem cells usually about one millionth of a meter in size and grows them for tissue engineering.

The fabrication and characterization of the patterns is an important part of the project. It has been shown that the actual patterns in which you grow the cells can influence their behavior greatly, so I am going to explore some of the implications of that.

What he learned at UTC has been critical to his success outside of the school, he says, including both the Japan internship and the one at Georgia Tech.

Im really thankful for the Honors College, as well as the faculty and staff of the CECS for all the help theyve given to me up to this point, he says. Ive been lucky enough to be around people and in an environment that has pushed me to pursue some really cool (and educational and professional) experiences and positions.

As for the difference between the societies in the U.S. and Japan, Mr. Thome understates that its quite different and, especially since I dont speak Japanese, it can be confusing at times.

In general, everyone here is extremely kind and helpful, though. Theres definitely a type of social structure and formality that isnt really prevalent in the United States.

Ive met a lot of people from all over the world here, too. Tsukuba is a science city with a high population of foreign researchers, and its really interesting to talk to people about various cultural differences.

Nanotechnology – Wikipedia, the free encyclopedia

Nanotechnology ("nanotech") is the manipulation of matter on an atomic, molecular, and supramolecular scale. The earliest, widespread description of nanotechnology[1][2] referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter that occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size. Because of the variety of potential applications (including industrial and military), governments have invested billions of dollars in nanotechnology research. Until 2012, through its National Nanotechnology Initiative, the USA has invested 3.7 billion dollars, the European Union has invested 1.2 billion and Japan 750 million dollars.[3]

Nanotechnology as defined by size is naturally very broad, including fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc.[4] The associated research and applications are equally diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale.

Scientists currently debate the future implications of nanotechnology. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials energy production, and consumer products. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials,[5] and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is warranted.

The concepts that seeded nanotechnology were first discussed in 1959 by renowned physicist Richard Feynman in his talk There's Plenty of Room at the Bottom, in which he described the possibility of synthesis via direct manipulation of atoms. The term "nano-technology" was first used by Norio Taniguchi in 1974, though it was not widely known.

Inspired by Feynman's concepts, K. Eric Drexler used the term "nanotechnology" in his 1986 book Engines of Creation: The Coming Era of Nanotechnology, which proposed the idea of a nanoscale "assembler" which would be able to build a copy of itself and of other items of arbitrary complexity with atomic control. Also in 1986, Drexler co-founded The Foresight Institute (with which he is no longer affiliated) to help increase public awareness and understanding of nanotechnology concepts and implications.

Thus, emergence of nanotechnology as a field in the 1980s occurred through convergence of Drexler's theoretical and public work, which developed and popularized a conceptual framework for nanotechnology, and high-visibility experimental advances that drew additional wide-scale attention to the prospects of atomic control of matter. In the 1980s, two major breakthroughs sparked the growth of nanotechnology in modern era.

First, the invention of the scanning tunneling microscope in 1981 which provided unprecedented visualization of individual atoms and bonds, and was successfully used to manipulate individual atoms in 1989. The microscope's developers Gerd Binnig and Heinrich Rohrer at IBM Zurich Research Laboratory received a Nobel Prize in Physics in 1986.[6][7] Binnig, Quate and Gerber also invented the analogous atomic force microscope that year.

Second, Fullerenes were discovered in 1985 by Harry Kroto, Richard Smalley, and Robert Curl, who together won the 1996 Nobel Prize in Chemistry.[8][9] C60 was not initially described as nanotechnology; the term was used regarding subsequent work with related graphene tubes (called carbon nanotubes and sometimes called Bucky tubes) which suggested potential applications for nanoscale electronics and devices.

In the early 2000s, the field garnered increased scientific, political, and commercial attention that led to both controversy and progress. Controversies emerged regarding the definitions and potential implications of nanotechnologies, exemplified by the Royal Society's report on nanotechnology.[10] Challenges were raised regarding the feasibility of applications envisioned by advocates of molecular nanotechnology, which culminated in a public debate between Drexler and Smalley in 2001 and 2003.[11]

Meanwhile, commercialization of products based on advancements in nanoscale technologies began emerging. These products are limited to bulk applications of nanomaterials and do not involve atomic control of matter. Some examples include the Silver Nano platform for using silver nanoparticles as an antibacterial agent, nanoparticle-based transparent sunscreens, and carbon nanotubes for stain-resistant textiles.[12][13]
