A unique combination of imaging tools and atomic-level simulations has allowed a team led by the Department of Energy's Oak Ridge National Laboratory to solve a longstanding debate about the properties of a promising material that can harvest energy from light.
Researchers from the Faculty of Chemical Technology, Kaunas University of Technology (KTU), Lithuania, are developing an artificial bone, which can be used for treating one of the most common joint diseases -- osteoarthritis. The bi-functional composite imitates the complex osteochondral structure of a joint, i.e. both cartilage and bone tissues.
The SR101 N-(3-[18F]Fluoropropyl) sulfonamide ([18F]SRF101) is a Sulforhodamine 101 derivative that was previously synthesised by our group. The fluorescent dye SR101 has been reported as a marker of astroglia in the neocortex of rodents in vivo. The aim of this study was to perform a toxicological evaluation of [18F]SRF101 and to estimate human radiation dosimetry based on preclinical studies.
Researchers from Tokyo Metropolitan University have discovered a new way of controlling the drying patterns formed by re-crystallizing salt. They found that the coffee ring effect can be used to pin the edge of drying droplets, creating a range of different geometric patterns. The same principles may be applied to understand and improve the adhesion of printer ink to surfaces and the manufacture of film-based devices.
Know that sickening feeling when you find your car banged up by a runaway shopping cart? It may become just a bad memory if auto body manufacturers make use of a new suite of tests developed by the National Institute of Standards and Technology (NIST) and three industry partners. Data from these tests could eventually help your vehicle's exterior better defend itself against dings, dents, scratches and things that go bump on the highway.
Drinking green tea has been linked to health benefits ranging from cardiovascular disease prevention to weight loss. Although many of these claims still need to be verified in the clinic, an antioxidant in green tea called epigallocatechin gallate (EGCG) appears to have beneficial effects in cells and animals. Now, researchers have found a surprising use for EGCG: sneaking therapeutic RNAs into cells. They report their results in ACS Central Science.
Researchers have developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. The enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable when they come into contact with oxygen. They are therefore not yet suitable for technological applications. The new protective mechanism is based on oxygen-consuming enzymes that draw their energy from sugar.
A team of researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) presents alternative approaches for versatile future applications of plastic magnets.
Kyungsuk Yum, an assistant professor in UTA's Materials Science and Engineering Department, and his doctoral student, Amirali Nojoomi, have developed a process by which 2-D hydrogels can be programmed to expand and shrink in a space- and time-controlled way that applies force to their surfaces, enabling the formation of complex 3-D shapes and motions.
A new wirelessly powered light-emitting device, which sticks onto animal tissue like a sticker with tissue-adhesive and elastic nanosheets, could possibly facilitate treatment for hard-to-detect microtumors and deeply located lesions that are hard to reach with standard phototherapy. If clinically applied, the device could be beneficial for cancer patients who seek minimally invasive treatment, helping them live longer and improve their quality of life.
