High-capacity battery material using salmon DNA

A Korean research team has succeeded in developing next-generation high-capacity cathode material for lithium-ion batteries. The Korea Institute of Science and Technology (KIST, Acting President Seok-jin Yoon) announced that the joint research team of Dr. Kyung Yoon Chung (head of the Center for Ene more
Catalyst deposition on fragile chips

Electrocatalysts can help to obtain chemicals from renewable raw materials or to use alternative energy sources. But testing new catalysts brings challenges. Researchers at the Ruhr-Universität Bochum (RUB) and the University of Duisburg-Essen have developed a new method of depositing catalyst parti more
First view of hydrogen at the metal-to-metal hydride interface

University of Groningen physicists have visualized hydrogen at the titanium/titanium hydride interface using a transmission electron microscope. Using a new technique, they succeeded in visualizing both the metal and the hydrogen atoms in a single image, allowing them to test different theoretical m more

Size and element specific determination of Ag nanoparticles in consumer spray products using asymmetric flow field flow fractionation (AF4) coupled to ICPMS

The use of nanoparticles in consumer products shows a tremendous increase over the past years. A study of the Woodrow Wilson International Centre for Scholars reported that between 2005 and today the number of products based on nanoparticles increase more

“Tubular J-Aggregates of a New Thiacarbocyanine Cy5 Dye for the Far-red Spectral Region – A Spectroscopic and Cryo-Transmission Electron Microscopy Study”

The aggregation behavior of a phenol-substituted thiacarbocyanine Cy5 dye (5-chloro-2-[5-[5-chloro-3-(4-sulfobutyl)-3H-benzothiazol-2-ylidene]-3-phenyl-penta-1,3-dienyl]-3-(4-sulfo¬butyl)-benzothiazol-3-ium hydroxide, inner salt, triethylammonium salt) in aqueous solution is investigated using stead more
In situ atomic-scale observation of inhomogeneous oxide reduction

We report in situ atomic-scale transmission electron microscopy observations of the surface dynamics during Cu2O reduction. We show inhomogeneous oxide reduction caused by the preferential adsorption of hydrogen at step edges that induces oxygen loss and destabilizes Cu atoms within the step edge, t 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
