His research focuses on nanocrystals -- a novel class of materials with features smaller than 100 nanometers -- as well as the development of innovative technologies enabled by nanocrystals. One nanometer is equal to one billionth of a meter. These technologies span the fields of molecular imaging, early cancer diagnosis, targeted drug delivery, biomaterials, regenerative medicine and catalysis.

The possible applications of nanotechnology in medicine have only begun to be explored, said Michael Cassidy, president and CEO of the Georgia Research Alliance. Dr. Xias expertise and collaborative vision will lead to vital new scientific discoveries that can be transformed into new tools to help people live healthier lives.

Dr. Xia is an international leader in the synthesis of nanomaterials designed to improve the way we live. He has been ranked as one of the top 10 chemists in the world, as well as the second most cited scientist in the fields of nanomedicine and materials science.

Dr. Xia is a world-renowned teacher and leader at the forefront of nanomedicine and materials science, said Larry McIntire, the Wallace H. Coulter Chair of Biomedical Engineering. His reputation and innovative research in these areas will clearly strengthen our expanding efforts in nanomedicine and biomaterials. We are honored to welcome him to the Department and to the Institute.

Regents' Professor and Chair of Chemistry and Biochemistry Charles Liotta said, Dr. Xia is an outstanding addition to our faculty in the School of Chemistry and Biochemistry. His research in nanomedicine and biomaterials lies at the interface between chemistry and engineering and fits in so well with the interdisciplinary culture at Georgia Tech. Dr. Xias presence will clearly enhance our efforts in these critical research areas.

Dr. Xia received his Ph.D. in physical chemistry from Harvard University (with Professor George M. Whitesides) in 1996, his M.S. in inorganic chemistry from University of Pennsylvania (with the late Professor Alan G. MacDiarmid, a Nobel Laureate in Chemistry, 2000) in 1993. He has received a number of prestigious awards, including AIMBE Fellow (2011), MRS Fellow (2009), NIH Director's Pioneer Award (2006), Leo Hendrik Baekeland Award (2005), Camille Dreyfus Teacher Scholar (2002), David and Lucile Packard Fellowship in Science and Engineering (2000), Alfred P. Sloan Research Fellow (2000), NSF Early Career Development Award (2000) and the ACS Victor K. LaMer Award (1999).

Feb. 28, 2012

A remarkable University of Wisconsin-Madison research triumph and artful renderings depicting the importance of biochemistry are the subject of a rare occurrence of the popular Wednesday Night @ the Lab series.

Held for one night only maybe, as there won't be another Wednesday night on a Leap Day until 2040 on Feb. 29 and in Room 1125 of the remodeled Biochemistry Building, 420 Henry Mall, this edition of the long-running science speaker series will give the audience an early public view of restored murals painted in the 1940s by John Steuart Curry.

The session begins at 7 p.m.

Lauren Kroiz, a UW-Madison art history professor, will talk about Curry's work as the first official artist-in-residence in the United States and the art he intended to enrich farmers' lives and encourage experimental agriculture. Curry's paintings in the Biochemistry Building were meticulously stabilized, cleaned and restored by conservators from the Midwest Art Conservation Center as the building was gutted and rebuilt.

David Nelson, biochemistry professor and lecturer in a course on historic research breakthroughs at UW-Madison, will discuss the discovery of vitamins by the likes of Stephen Babcock, E.B. Hart, Harry Steenbock, and E.V. McCollum (all depicted in Curry's murals) in UW-Madison's agricultural chemistry department.

Wednesday Night @ the Lab which is sponsored by BioTrek, the Science Alliance, the Wisconsin Alumni Association and the Osher Lifelong Learning Institute is free and open to the public. There will be free parking in Lot 20, located nearby at 1390 University Ave.

The Biochemistry, Food and Inorganics Sciences are three new key categories covered by the Sciences Social Network ScienceIndex.com. The users of the website monitor over 130 scientific Biochemistry, Food and Inorganics journals and submit the most significant scientific results of these journals for inclusion in ScienceIndex.com. ScienceIndex.com was established in 1998 to index the very latest news, headlines, references and resources from science journals, books and websites worldwide. The site covers news in all fields of biology, business, chemistry, engineering, geography, health, mathematics and society.

Mannheim, Germany (PRWEB) February 27, 2012

ScienceIndex.com is a Web 2.0 sciences social network established in 1998 to index the very latest news, headlines, references and resources from science journals, books and websites worldwide. The site covers news in all fields of biology, business, chemistry, engineering, geography, health, mathematics and society. In the field of Chemistry, the site has now included the three new categories Biochemistry, Food and Inorganics. While the Biochemistry category covers the chemical substances and vital processes in living organisms, the Food category covers production of materials of plant or animal origin, that are ingested and assimilated by an organism to produce energy, stimulate growth, and maintain life, and the Inorganics category covers chemical reactions and properties of all elements in the periodic table and their compounds, except element carbon.

ScienceIndex.com's Chemistry Sciences Category covers the composition, structure, properties, and reactions of substances. Its seven subsections include Biochemistry, Food, Inorganics, Materials, Organics, Physics and Toxicology.

ScienceIndex.com's Biochemistry Sciences Category covers covers the chemical substances and vital processes in living organisms. It currently contains over 18,500 articles partly derived from over 40 scientific journals. One of the latest additions covers novel oxidative stress transcription factor. Hypochlorite is a powerful oxidant produced by neutrophils to kill invading microorganisms. Despite this important physiological role of hypochlorite in fighting bacterial infections, no hypochlorite-specific stress response has been identified yet. The authors identified a hypochlorite-responsive transcription factor, YjiE, which is conserved in proteobacteria and eukaryotes. To their knowledge, YjiE is the first described hypochlorite-specific transcription factor specifically conferring hypochlorite resistance to E. coli cells.

ScienceIndex.com's Food Sciences category covers production of materials of plant or animal origin, that are ingested and assimilated by an organism to produce energy, stimulate growth, and maintain life. It currently contains nearly 11,800 articles partly derived from almost 50 scientific journals. One recently included article in this category covers a review of osmotic dehydration of fruits and vegetables. Osmotic dehydration is one of the best and suitable method to increase the shelf life of fruits and vegetables since this process retains vitamin and minerals, color, flavor and taste in fruits and vegetables. The authors review different methods, treatments, optimization and effects of osmotic dehydration. Their results show that combination of different osmotic agents are more effective than sucrose alone due to combination of properties of solutes.

ScienceIndex.com's Inorganics Sciences Category covers chemical reactions and properties of all elements in the periodic table and their compounds, except element carbon. It currently contains nearly 6,200 articles partly derived from over 40 scientific journals. One of the latest additions characterizes work hardening mechanisms in Fe–Mn based TWIP steels. When strained in tension, high-manganese austenitic twinning induced plasticity (TWIP) steels achieve very high strength and elongation before necking. The authors show that the Fe–Mn–C grade exhibits the best properties, together with a Portevin–Le Châtelier effect which could result in supplementary hardening. Furthermore, TEM analyses show that twins in the Fe–Mn–C steel are thinner and without dislocation activity, which could lead to a composite effect and increase the work hardening.
