• How to produce microlenses from dyes
  Researchers are on the lookout for rapid, reliable and affordable switches for the opto-electronics of the future. An Empa team now presents a potential solution: dye droplets measuring just a few ...
• New receptor found on scavenger cells
  Adenoviral infections have a mild disease progression in healthy people, but it can be dangerous for immunocompromised people. If a patient is infected with the virus and gets a bacterial infection...
• Faster, more precise, more stable: Study optimizes graphene growth
  Each atomic layer thin, tear-resistant, and stable. Graphene is seen as the material of the future. It is ideal for e.g. producing ultra-light electronics or highly stable mechanical components. Bu...
• More inflexible than imagined
  Oligosaccharides - chains of sugar building blocks - are some of the most important molecules in living creatures. They make up a large part of the surface of cells and contribute to the immune sys...
• How a bacterium can live on methanol
  ETH Zurich researchers have identified all the genes required by a bacterium to use methanol as a food source. The results will help scientists advance the use of this resource in the field of biot...
• Nanomaterial wrap for improved tissue imaging
  Researchers at Tokai University describe in Advanced Materials how wrapping biological tissue in a nanosheet of a particular organic material results in high-quality microscopy images. Application...
• A powerful tool for 3-D and multicolor STED imaging of cellular ultrastructure
  Chemists at ITbM, Nagoya University have developed a super-photostable fluorescent dye, PhoxBright 430 (PB430), to visualize cellular ultrastructure by super resolution microscopy. The exceptional ...
• Boron nitride foam soaks up carbon dioxide
  Rice University materials scientists have created a light foam from two-dimensional sheets of hexagonal-boron nitride (h-BN) that absorbs carbon dioxide. They discovered freeze-drying h-BN turne...
• Recovering phosphates from sewage sludge
  Sewage sludge contains lots of valuable elements which are prized as fertiliser for use in agriculture. Phosphorus in particular is an important nutrient for plants. Researchers at Landshut Univers...
• New chemistry preprint server for the global chemistry community
  ChemRxiv, a new chemistry preprint server for the global chemistry community, is now available in a fully functioning Beta version for use and feedback by researchers. The Beta launch has been u...
• Killing bacteria by hacking plastics with silver and electricity
  Researchers at the Swedish Medical Nanoscience Center at Karolinska Institutet have developed an innovative way of hacking conducting plastics so as to prevent bacterial growth using silver nanopar...
• Using electrochemistry to amp up drug manufacturing
  Give your medicine a jolt. By using electrochemistry, future pharmaceuticals - including many of the top prescribed medications in the United States - soon may be easily scaled up to be manufacture...
• New ultrafast method for determining antibiotic resistance
  Researchers at Uppsala University have developed a new method for very rapidly determining whether infection-causing bacteria are resistant or susceptible to antibiotics. The findings have now been...
• New mechanisms of protein transport in plant cells discovered
  Unlike many other organisms, plants can't simply run away from environmental conditions that change for the worse. Nonetheless, plants have the ability to react to environmental effects. These reac...
• Stabilizing gold in very rare oxidation state +II
  According to text book knowledge, the usual oxidation states of gold in compounds are +I and +III. The divalent form (+II), on the other hand, prefers to form polynuclear compounds or simply underg...
• New model for bimolecular reactions in nanoreactors
  Theoretical physicists have devised a mathematical model of two different molecules reacting within so called nanoreactors that act as catalysts. They gained surprising new insights as to what fact...
• Converting CO₂ to multicarbon fuels
  Chemists have figured out a new, more efficient way to create carbon-based fuels from carbon dioxide (CO₂). In chemical reactions performed in the lab, a Caltech team has identified a new additive ...
• Clarifiying complex chemical processes with quantum computers
  Science and the IT industry have high hopes for quantum computing, but descriptions of possible applications tend to be vague. Researchers at ETH Zurich have now come up with a concrete example tha...
• One-nanometer trimetallic alloy particles created
  A researcher group of Tokyo Institute of Technology succeeded in developing precisely controlled alloy nanoparticles "multimetallic nanoclusters (MNCs)" made of three metals: copper, platinum, and ...
• Revealing effects of using chemicals
  The number of insects in Germany is declining rapidly - in the state of North Rhine-Westphalia alone, it has dropped by three-quarters within only 25 years. In a new study, biologists at Bielefeld ...
• Natural molecule to boost the performance of electrodes for rechargeable batteries
  Chlorophyll, blood, and vitamin B12 are all based on the porphyrin molecule. But porphyrin can also be used as an electrode material where it speeds up the charging process of rechargeable batterie...
• Antiaromatic molecule displays record electrical conductance
  Researchers demonstrate high electrical conductance for an antiaromatic nickel complex - an order of magnitude higher than for a similar aromatic complex. Since the conductance is also tunable by e...
• Structure of an enzyme that supplies carotenoid
  The lack of vitamin A in food is a major cause of health problems worldwide and can lead to blindness and even death. This is especially a problem in threshold or third-world countries, where child...
