Water which has been contaminated with mercury and other toxic heavy metals is a major cause of environmental damage and health problems worldwide. Now, researchers from Chalmers University of Technology, Sweden, present a totally new way to clean contaminated water, through an electrochemical process. The results are published in the scientific journal Nature Communications.
In recent years, cities have asserted themselves as relevant actors in efforts to address global climate change. The announcement by the United States of their intent to withdraw from the Paris Agreement has generated more attention than ever for what cities and other subnational authorities can do in this field.
Sustainable method to neutralize poisonous carbon monoxide named 'nano-raspberry' was developed by the NITech scientists, which is a raspberry-shaped nanoparticle capable of losing the most potent toxicity of carbon monoxide.
When the tension rises, unexpected things can happen -- not least when it comes to gold atoms. Researchers from, among others, Chalmers University of Technology, Sweden, have now managed, for the first time, to make the surface of a gold object melt at room temperature.
A University of Melbourne researcher has led the successful development of an organic, non-combustible and lightweight cladding core -- a product that was previously thought to be impossible to create.
University of Cincinnati geography professor Tomasz Stepinski created a new world map showing dramatic changes in land use over the last quarter century. Stepinski turned high-resolution satellite images from the European Space Agency into one of the most detailed looks so far at how people are reshaping the planet.
A RUDN chemist developed a new method of obtaining a porous carbon material on the basis of Chinese flour and water. The samples of the material exhibited high electrocatalytic activity in the course of production of hydrogen -- an eco-friendly energy source. The results of the work were published in Electrochimica Acta.
Researchers at the University of Marburg highlight the ability of computational chemistry approaches using high-performance computing to reveal interesting phenomena that occur between organic molecules and surfaces. They also demonstrate more generally how these interactions can be understood with respect to the molecular and solid state world. Understanding surface chemistry in this way could be useful in designing patterned surfaces, a goal of scientists working on the next generation of more powerful, more efficient semiconductors.
Researchers at Idaho National Laboratory have discovered how to make 'superalloys' even more super, extending useful life by thousands of hours. The discovery could improve materials performance for electrical generators and nuclear reactors.
A catalyst for carbon dioxide recycling, Mineral pentlandite may also be a conceivable alternative to expensive precious metal catalysts. This is the result of a study conducted by researchers from Ruhr-Universität Bochum (RUB), Fritz-Haber Institute Berlin and Fraunhofer Umsicht in Oberhausen. Pentlandite had previously been known as a catalyst for hydrogen production. By adding a suitable solvent, the researchers successfully utilised it to convert carbon dioxide into carbon monoxide. The latter is a common source material in the chemical industry.
