Without a doubt, the market for electric vehicles is growing rapidly. While we are still in the initial phase there are several signs that the Hybrid Electric Vehicle (HEV) market is emerging from its infancy. Figures from the International Council on Clean Transportation (ICCT) confirm this; whereas in 2010 the worldwide electric vehicle market was more or less zero, by 2015 over half a million electric cars had been sold - and sales are continu...

Researchers at the University of Sydney have applied quantum techniques to understanding the electrolysis of water, which is the application of an electric current to H2O to produce the constituent elements hydrogen and oxygen.They found that electrons can 'tunnel' through barriers in aqueous solutions away from the electrodes, neutralising ions of impurities in that water. This can be detected in changes in current, which has applications for bi...

Harnessing the Sun’s radiation to help rid the oceans of microplastics contamination is one of several technical innovations to be developed by a new EU-funded project. Beginning in November 2017, a system developed at KTH Royal Institute of Technology in Sweden for breaking down microplastics from personal care products will be tested for implementation in homes and wastewater treatment plants.

A development in aluminum electrolytic technology from Cornell Dubilier Electronics (CDE) is now in stock at New Yorker Electronics. The CDE 85°C THA Series ThinPack capacitors are only 8.2mm thick, and only 9mm in the 105°C THAS Series. Comparable in height to V-chip electrolytics, tantalums and board-mounted axials, the THA and THAS offer much higher bulk-storage energy density.

A group of Brazilian astronomers observed a pair of celestial objects rarely seen in the Milky Way: a very low-mass white dwarf and a brown dwarf.A white dwarf is the endpoint of the evolution of an intermediate- or low-mass star, with a mass between 0.5 and 8 times that of our Sun. A brown dwarf is a substellar object with mass intermediate between those of a star and a planet.

It's possible to produce hydrogen to power fuel cells by extracting the gas from seawater, but the electricity required to do it makes the process costly. UCF researcher Yang Yang has come up with a new hybrid nanomaterial that harnesses solar energy and uses it to generate hydrogen from seawater more cheaply and efficiently than current materials.

Researchers at Chalmers University of Technology and the Technical University of Denmark have developed a method that makes it possible to map the individual responses of nanoparticles in different situations and contexts. The results pave the way for better nanomaterials and safer nanotechnology and were recently published in the journal Nature Communications.

Power on the go is in demand: The greater the battery capacity, the larger the reach of electric cars and the longer the operating time of cell phones and laptops. Dr. Jennifer Ludwig of the Technical University of Munich (TUM) has developed a process that allows the promising lithium cobalt phosphate cathode material to be produced quickly, easily, cost-effectively and in high quality. The chemist was awarded the Evonik Research Prize for her wo...

The 2011 Fukushima nuclear disaster was the most costly nuclear related incident since Chernobyl 25 years earlier. It was caused by a tsunami following the Tohoku earthquake, which disabled the emergency generators that were employed to cool the reactors. This insufficient cooling led to three nuclear meltdowns, hydrogen-air explosions and the release of radioactive materials.

A ceramic-based mechanical pump able to operate at record temperatures of more than 1,400ºC (1,673K) can transfer high temperature liquids such as molten tin, enabling a new generation of energy conversion and storage systems.
