Liquid electrolytes are essential components in a variety of emerging energy technologies, including batteries, supercapacitors and solar-to-fuel devices. “To predict and optimize the performance of these devices, a detailed understanding of the electrolytes, particularly their electronic properties such as the ionization potential and electron affinity, is critical,” said Anh Pham, a Lawrence Livermore National Laboratory (LLNL) Lawrence fellow in the Quantum Simulations Group, and the lead author of a paper in an edition of Science Advances.

Northern China’s roadsides are peppered with deciduous Phoenix trees, producing an abundance of fallen leaves in autumn. These leaves are generally burned in the colder season, exacerbating the country’s air pollution problem. Investigators in Shandong, China, recently discovered a new method to convert this organic waste matter into a porous carbon material that can be used to produce high-tech electronics. The advance is reported in the Journal of Renewable and Sustainable Energy, by American Institute of Physics (AIP) Publishing. Read more

 

The European Union (EU) has set new rules to protect workers from carcinogens and mutagens in the workplace. Employers will have to assess the risk of exposure for workers and take preventive measures. This should tackle the primary cause of work-related deaths in the EU, i.e. cancer. The aim is to help save up to 100 000 lives over the next 50 years. It includes a lower occupational exposure limit (OEL), – a maximum quantity of harmful substances that workers can be exposed to, for: chromium VI, used in textile dyes, paints and leather tanning materials and generated during the casting, welding or cutting of stainless steel. Read more

Non-stick coating runs afoul of the spores


Researchers at the University of Wollongong (UOW) led ARC Research Hub for Australian Steel Manufacturing have been investigating self-cleaning, anti-microbial organic coatings for painted sheet steel to prevent the build-up of mould, algae and other bacteria on coated steel products, particularly in humid environments. Left unchecked, a build-up of troublesome organisms wreaks havoc on steel products, requiring more regular and costly cleaning and maintenance. Read more

 

 

Packing tiny solar cells together, like micro-lenses in the compound eye of an insect, could pave the way to a new generation of advanced photovoltaics, said Stanford University scientists. In a new study, the Stanford team used the insect-inspired design to protect a fragile photovoltaic material called perovskite from deteriorating when exposed to heat, moisture or mechanical stress. The results are published in the journal Energy & Environmental Science (E&ES). Read more

 

At $2.45, the current US gas price average is the highest recorded price for a gallon of unleaded gasoline so far, this year, due to the impact of Hurricane Harvey, according to a report by The American Automobile Association (AAA). The near-term combinations of numerous refinery and pipeline shut downs, tightened access to supply levels in the Gulf and anticipated high gasoline demand surrounding Labor Day weekend, means motorists may not have seen the full impact of Harvey at the pump.

Royal DSM has introduced a material solution for high-pressure composite tanks for hydrogen storage in its continuing mission to help reduce CO2 emissions. Hydrogen tanks are the next step in fuel storage, as such storage is a key enabling technology for advancing hydrogen and fuel cell technologies in applications that include stationary power, portable power and transportation. Hydrogen has the highest energy per mass of any fuel. One kg of hydrogen is equivalent to 33.3 kWh. Read more
