Nitrogen-doped carbon nanotubes or modified graphene nanoribbons may be ideal replacements for platinum, used for rapid oxygen reduction.
Carbon footprint can be drastically reduced by replacing the everyday gas guzzler with a hydrogen fueled car. So why cannot everyone make the switch?
Methane is the main constituent of natural gas. The direct oxidation of this compound into methanol at low temperatures has traditionally been a holy grail.
Studies of lithium-ion batteries have paved the way for plentiful probabilities in designing next-generation batteries. Specifically, the metal-air batteries—with considerably higher energy density similar to that of 1 kg of gasoline—have of late been accepted and invested for by some of the pioneering companies in the world, such as IBM.
Leaky sulfur-acid automobile batteries may be a thing of the past, but current generation of lithium batteries still continues to have some disadvantages. Now, a group of engineers at Penn State have developed a unique kind of lithium sulfur battery that could be safer, more efficient, and less expensive.
An additive for conventional fuel made up of oxygenated organic compounds could help in reducing the discharge of pollutants into the atmosphere during the combustion of fossil fuels. The aspect of how these potential additives decompose under combustion-relevant conditions has recently been established by KAUST researchers.
A new synthesis route for alternative catalysts of noble metals have been developed by researchers for multipurpose chemical reactions that could help deal with environmental concerns.
Researchers believe hydrogen will be the prospective energy source in the future. Hydrogen is synthesized by using solar power and can be used to produce electricity and heat in fuel cells. At present, scientists at Empa have been successful in deciphering the movement of hydrogen ions in crystals.
For the first time, Researchers from the Helmholtz-Zentrum Berlin (HZB) have developed a nanomaterial produced from nanoparticles of a titanium oxide compound—namely, Ti4O7 (having an exceptionally large surface area)—and analyzed its usage as a cathode material in lithium-sulfur batteries.
Materials researchers from the Paul Scherrer Institute (PSI) in Switzerland have worked in cooperation with the Université Grenoble Alpes, France, to develop a technique for enabling advancement of the lithium-sulfur battery. Theoretically, lithium-sulfur batteries have the ability to provide remarkably more energy when compared to the currently used traditional lithium-ion batteries.
