Alfa Aesar, now part of Thermo Fisher Scientific is a leading manufacturer and supplier of chemicals, metals, and life science products for research and development. For more than 50 years, scientists have relied on Alfa Aesar to supply high purity raw materials for a variety of research and dev more
A globally leading technology group, Heraeus is headquartered in Hanau, Germany. Founded in 1851, it is a family-owned portfolio company which traces its roots back to a pharmacy opened by the family in 1660. Today, Heraeus combines businesses in the environmental, energy, electronics, health, mobil more
Nano-Join GmbH is a young technology company based in Berlin. Our innovative sintering solutions are primarily aimed at making high-performance electronic components from the fields of optoelectronics, e-mobility and renewable energies more powerful and efficient. However, we also see other fields o more
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
Mark Greiner and Travis Jones from the Max-Planck Institute for Chemical Energy Conversion and the Fritz-Haber Institute, along with a team of international researchers, have recently made a discovery that could transform the way chemicals are synthesized. The chemical industry relies on high-perfo more
A new form of solar-powered supercapacitor could help make future wearable technologies lighter and more energy-efficient, scientists say. Researchers from the University of Glasgow’s Bendable Electronics and Sensing Technologies (BEST) group describe how they have developed a promising new type of more
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
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
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
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
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
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
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
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
