Greener solar cells are based on AgBiS2 nanocrystals
ICFO researchers Dr. Maria Bernechea, Dr. Nicky Miller, Guillem Xercavins, David So, and Dr. Alexandros Stavrinadis, led by ICREA Prof. at ICFO Gerasimos Konstantatos have fabricated a solution-processed, semi-transparent solar cell based on AgBiS2 nanocrystals, a material that consists of non-toxic, earth-abundant elements, produced in ambient conditions at low temperatures.
Technology to take hold in Rio
Technology will play a more integral role in this year’s Olympic Games in Rio De Janeiro than ever before. Nicolette Emmino takes a closer look.The Olympic Games - with their roots stretching way back to ancient Greece - have seen a shift in attitudes over the years, as technology is now a crucial element of how people relate to the behemoth sporting event.
CDM Electronics offers titan ground PowerT cable assemblies
CDM Electronics has announced the availability of Eaton's Titan Ground Power Series of cable assemblies and field-replaceable adapters for commercial and military aircraft. The parts' advanced interconnect technologies decrease mating forces by 40% and demating by 60% to extend aircraft power receptacle life and reduce receptacle-related Aircraft On Ground (AOG) expenses and schedule delays.
700-year-old soil technique could mitigate climate change
A farming technique practised for centuries by villagers in West Africa, which converts nutrient-poor rainforest soil into fertile farmland, could be the answer to mitigating climate change and revolutionising farming across Africa.A global study, led by the University of Sussex, which included anthropologists and soil scientists from Cornell, Accra, and Aarhus Universities and the Institute of Development Studies, has for the first-time identifi...
Sunlight and water could produce renewable hydrogen power
University of Iowa researchers are working with a California-based startup company to make clean energy from sunlight and any source of water. The university recently renewed a one-year research agreement to further develop the technology with HyperSolar, a company that aims to commercialise low-cost renewable hydrogen. Hydrogen power is arguably one of the cleanest and greenest energy sources because when it produces energy, the final byproduct ...
Loofah-based material could give lithium batteries a boost
Today's mobile lifestyle depends on rechargeable lithium batteries. But to take these storage devices to the next level—to shore up the electric grid or for widespread use in vehicles, for example—they need a big boost in capacity. To get lithium batteries up to snuff for more ambitious applications, researchers report in the journal ACS Applied Materials & Interfaces a new solution that involves low-cost, renewable loofah sponges...
Second phase of programme to fund apprentices for SMEs
Close Brothers has announced the launch of phase two of its SME Apprenticeship Programme, in partnership with manufacturers’ organisation EEF and the Manufacturing Technologies Association (MTA).
Succinic acid can be obtained from wood waste
The present-day chemical industry is based on oil. Many chemical products – from plastics through to detergents and solvents to medication and crop protection products – have their origins in oil and its constituents. Since oil reserves are finite, scientists have been looking for ways to manufacture these products from sustainable materials.An international research team has now demonstrated just such an alternative manufacturing met...
High-entropy alloys convert waste heat to electricity
An interdisciplinary project at Chalmers has found that a special class of material – high-entropy alloys – can open the door to efficient heat recycling.Boosting energy efficiency is an important element of the transition to a sustainable energy system. There are big savings to be made. For example, less than half the energy content of diesel is actually used to power a diesel truck. The rest is lost, mostly in the form of heat. Many...
Towards eco-friendly industrial-scale hydrogen production
What if industrial waste water could become fuel? With affordable, long-lasting catalysts, water could be split to produce hydrogen that could be used to power fuel cells or combustion engines. By conducting complex simulations, scientists showed that adding lithium to aluminum nanoparticles results in orders-of-magnitude faster water-splitting reactions and higher hydrogen production rates compared to pure aluminum nanoparticles. The lithium all...
