• Little Heaps of Silver, All Wrapped Up
  

  Nanoclusters are little “heaps” of a few atoms that often have interesting optical properties and could become useful probes for imaging processes in areas such as biomedicine and diagnostics. In the journal Angewandte Chemie, researchers have introduced a nanocluster of 16 silver atoms stabilized b more

• Analytical tool designs corkscrew-shaped nano-antennae
  

  For the first time, an HZB team has derived analytically how corkscrew-shaped nano-antennas interact with light. The mathematical tool can be used to calculate the geometry that a nano-antenna must have for specific applications in sensor technology or information technology. The nanostructures from more

• Carrying and releasing nanoscale cargo with 'nanowrappers'
  

  This holiday season, scientists at the Center for Functional Nanomaterials (CFN)--a U.S. Department of Energy Office of Science User Facility at Brookhaven National Laboratory--have wrapped a box of a different kind. Using a one-step chemical synthesis method, they engineered hollow metallic nanosiz more

• Battling Corrosion in Refineries
  

  Corrosion in refinery operations has been, and still is, the subject of many studies, papers, courses and web forums. Although a lot of what has been written shows that significant progress in understanding corrosion has been made, it also makes it more

• Battery Cycling
  

  Lithium Ion is becoming the technology choice for HEV, PHEV, as well as many stationary applications. With such large battery packs it is important to understand how the individual cells and packs will behave in a variety of scenarios. One of the mai more

The Composition of the Rio Olympics Medals

If you’ve been watching the Olympics, you might have assumed that the medals given out are, as advertised, made of gold, silver, and bronze. Due to metal values, however, the reality is slightly more complicated. Giving out pure gold medals would be financially crippling for the International Olympi more

The Chemistry of Sunglasses

Summer’s fast approaching in the northern hemisphere, it seems an appropriate time to be taking a look at the chemistry of sunglasses. What are they made of, how do they protect your eyes, and how do photochromic sunglasses work? more

The Chemistry of Diamond Rings

Diamonds might purportedly be ‘a girl’s best friend’, but they’re also quite interesting from a chemical perspective. You could be forgiven for thinking that there’s not a whole lot to them; after all, they’re simply one of the possible forms of carbon, formed at high pressure beneath the Earth’s su more

• Silver(I)-catalyzed sequential hydroamination and Prins type cyclization for the synthesis of fused benzo--sultams

  An intramolecular annulation strategy has been developed for the synthesis of tetrahydrobenzo[e]pyrano[4,3-c][1,2]thiazine derivatives by means of coupling of aldehydes with 2-(4-hydroxybut-1-yn-1-yl)-N-arylsulfonamides using a catalytic amount of silver hexafluoroantimonate in toluene at 80 °C. Thi more

• Ab-initio design of light absorption through silver atomic clusters decoration of TiO2

  A first-principle study of the stability and optical response of subnanometer silver clusters Agnn (n ≤5) on a TiO2(110) surface is presented. First, the adequacy of the vdW-corrected DFT-D3 approach is assessed using the domain-based pair natural orbital correlation approach DLPNO-CCSD(T) along wit more

• Silver nanoparticle embedded copper oxide as an efficient core–shell for the catalytic reduction of 4-nitrophenol and antibacterial activity improvement

  A facile and eco-friendly method was developed to prepare a microporous CuO@Ag0 core–shell with high catalytic and antibacterial activities. Scanning and transmission electron microscopy revealed a preponderance of nearly spherical 50 nm particles with slight structure compaction. Comparison of the more
