Developing a hydrogen economy is no easy endeavor, however, Rice University engineers have identified a mechanism that could make oxygen evolution catalysis in acids, one of the most difficult problems in water electrolysis for producing clean hydrogen fuels, more cost-effective and practical.
Scientists from Romania have evaluated the use of bacteria to improve mortar in construction applications, investigating several different strains. Their findings have been published in the journal Materials.
The Haber-Bosch process, which is widely used to produce ammonia (NH3)—the basis for synthetic nitrogen fertilizers—by blending hydrogen (H2) and nitrogen (N2) over catalysts at high pressures and temperatures—is among the most significant scientific discoveries that have helped to improve crop yields and boost global food production.
A new high-profile scientific review article in Nature Reviews Chemistry discusses how carbon dioxide (CO2) converts from a gas to a solid in ultrathin films of water on underground rock surfaces. These solid minerals, known as carbonates, are both stable and common.
Imagine a typical recycling plant. Now imagine that the plant is a chemistry lab, and the crushed soda cans and waist-high stacks of junk mail have been replaced by microscopic structures worth tens of thousands of dollars per gram.
Hydrogen gas could someday replace fossil fuels as a "clean" energy source, producing only water and energy.
Researchers from the Van ’t Hoff Institute for Molecular Sciences of the University of Amsterdam offer a method that enables the transition of photocatalysis from the laboratory to the industry in a paper published in Nature Communications.
Alcohols are used to remove impurities on the surface of semiconductors or electronics during the manufacturing process, and wastewater containing alcohols is treated using reverse osmosis, ozone, and biological decomposition.
Scientists can convert carbon dioxide, a greenhouse gas, into higher value multicarbon products, seen as intermediates for potential fuels. In this research, scientists examined a new approach to this conversion process. The approach uses a material called a tandem catalyst-;an electrode with two catalytic regions.
Scientists have long been fascinated with the origin of life on Earth, namely the transition from simple pre-biotic organic molecules to living cell systems.
