Scientists have succeeded in developing a nickel complex that changes color and magnetism when exposed to methanol vapor. The new material can potentially be used not only as a chemical sensor, but also with future rewritable memory devices.
Proton therapy is a promising form of radiation treatment used to kill cancerous cells and effectively halt their rapid reproduction, and the fundamental understanding for it is contained in the radiation induced water chemistry that occurs immediately after the interaction. The ensuing processes are therefore a subject of considerable scientific interest.
Researchers have discovered a new form of the simple compound GeSe that has surprisingly escaped detection until now. This so-called beta-GeSe compound has a ring type structure like graphene and could have similarly valuable properties for electronic applications.
Hydrogen is both the simplest and the most-abundant element in the universe, so studying it can teach scientists about the essence of matter. And yet there are still many hydrogen secrets to unlock, including how best to force it into a superconductive, metallic state with no electrical resistance.
Nanocars will compete for the first time ever during an international molecule-car race on April 28-29, 2017 in Toulouse (south-western France). The vehicles, which consist of a few hundred atoms, will be powered by minute electrical pulses during the 36 hours of the race, in which they must navigate a racecourse made of gold atoms, and measuring a maximum of a 100 nanometers in length.
Cryo-electron microscopy (cryo-EM) -- which enables the visualization of viruses, proteins, and other biological structures at the molecular level -- is a critical tool used to advance biochemical knowledge. Now researchers have extended cryo-EM's impact further by developing a new computational algorithm instrumental in constructing a 3-D atomic-scale model of bacteriophage P22 for the first time.
A group researchers has developed a manufacturing method for electrocatalysts that only uses one hundredth of the amount of platinum generally used in commercial products. The activity achieved using the new material is similar to that of commercial electrocatalysts. The method is based on the special characteristics of carbon nanotubes.
A new project aims to create an efficient, simple-to-manufacture oxygen-evolution catalyst that pairs well with semiconductors for advanced solar cells. The technique could lead to unique catalysts for other applications.
Scientists have developed a self-healing membrane for hydrogen fuel cells; typical membranes, a crucial component of the cells, are prone to cracks and pinholes. This discovery showcases membranes that can fix themselves.
Milling electronic waste into nanoscale particles allows polymers, oxides and metals to be separated for recycling into new products. The process takes advantage of changes to the materials' properties in very cold conditions.
Scientists have succeeded in ‘filming’ inter-molecular chemical reactions – using the electron beam of a transmission electron microscope (TEM) as a stop-frame imaging tool. They have also discovered that the electron beam can be simultaneously tuned to stimulate specific chemical reactions by using it as a source of energy as well as an imaging tool.
Mercury is very toxic and can cause long-term health damage, but removing it from water is challenging. To address this growing problem scientists have created a sponge that can absorb mercury from a polluted water source within seconds.
Researchers have developed the next step in microbial fuel cells (MFCs) with the first micro-scale self-sustaining cell, which generated power for 13 straight days through symbiotic interactions of two types of bacteria.
