The most wear-resistant metal alloy in the world

17-Aug-2018

If you're ever unlucky enough to have a car with metal tires, you might consider a set made from a new alloy engineered at Sandia National Laboratories. You could skid -- not drive, skid -- around the Earth's equator 500 times before wearing out the tread. Sandia's materials science team has ...

Catalysts combination opens doors to making useful compounds

17-Aug-2018

Researchers have developed a new method that aids in the process of making valuable compounds by using a unique combination of catalysts. Huimin Zhao, Professor of Chemical and Biomolecular Engineering and leader of the Biosystems Design research theme at the Carl R. Woese Institute for Genomic ...

Particles pull last drops of oil from well water

Nanoscale solution to ‘produced water’ problem

17-Aug-2018

Oil and water tend to separate, but they mix well enough to form stable oil-in-water emulsions in produced water from oil reservoirs to become a problem. Rice University scientists have developed a nanoparticle-based solution that reliably removes more than 99 percent of the emulsified oil that ...

Smart Fluorescent Dyes

Modulating photo- and electroluminescence in a stimuli-responsive molecular dye

17-Aug-2018

Controlling the excited electronic states in luminescent systems remains a challenge in the development of fluorescent and phosphorescent dyes. Now, scientists in Japan have developed a unique organic fluorophore that changes its emission color without loss of efficiency when externally ...

Molecular switch detects metals in the environment

Chemical sensor capable of detecting the presence of metals

17-Aug-2018

An international team, led by researchers from the University of Geneva (UNIGE), Switzerland, has designed a family of molecules capable of binding to metal ions present in its environment and providing an easily detectable light signal during binding. This new type of sensor forms a 3D structure ...

An effective approach to optimizing medicinal molecules

16-Aug-2018

The search for new medicinal molecules with predetermined properties is a rather complex, expensive and time-consuming process, especially in oncology. Modern science allows us to accelerate this search through the use of computer technology and the introduction of automated processes. In the ...

A computational method for designing a new type of 2D carbons

16-Aug-2018

Zeolites are porous minerals that occur both naturally but also are being synthesized artificially. Because of their stability and durability, they are used in industrial water purification, catalysis, adsorption, and even in blood-clotting powders (e.g. QuickClot used by the US military). A ...

'Building up' stretchable electronics to be as multipurpose as your smartphone

16-Aug-2018

By stacking and connecting layers of stretchable circuits on top of one another, engineers have developed an approach to build soft, pliable "3D stretchable electronics" that can pack a lot of functions while staying thin and small in size. As a proof of concept, a team led by the University of ...

Converting carbon dioxide into methane or ethane selectively

16-Aug-2018

A research team led by Professor Su-Il In from Department of Energy Science and Engineering had succeeded in developing photo catalysts that can convert carbon dioxide into usable energy such as methane or ethane. As carbon dioxide emissions increase, the Earth's temperature rises and interest in ...

Hybrid nanomaterials bristle with potential

16-Aug-2018

By combining multiple nanomaterials into a single structure, scientists can create hybrid materials that incorporate the best properties of each component and outperform any single substance. A controlled method for making triple-layered hollow nanostructures has now been developed at KAUST. The ...
