An international team of scientists from ESRF, SLAC, Virginia Tech and Purdue University wanted to understand and quantitatively define what leads to the failure of lithium-ion batteries. Previously, studies have either focussed on individual areas or particles in the cathode during failure or examined behaviour at … Weiterlesen …

Organic phototransistors (OPTs) are widely used in environmental as well as health monitoring, quantum communication, chemical and biomedical sensing, remote control, surveillance, and image sensors. They are outstanding for their low-cost, light-weight, high efficiency, and environmental friendliness. The interfacial charge … Weiterlesen …

Polymers are usually the go-to material for thermal insulation. Think of a silicone oven mitts or a Styrofoam coffee cup, both items are manufactured from polymer-based materials that are excellent at trapping heat. Now, engineers from Massachusetts Institute of Technology (MIT) have … Weiterlesen …

To prevent the disastrous effects of global climate change, man-made greenhouse gas emissions must be reduced to “zero” over the next three decades. This is clear from the current special report of the Intergovernmental Panel on Climate Change (IPCC). The … Weiterlesen …

An international research team led by Professor Jodie Bradby of Australian National University (ANU) has created a new type of silicon that better uses sunlight and promises to cut the cost of solar technology. The researchers say their invention could help reduce the costs … Weiterlesen …

Natural gas and biogas have become increasingly popular sources of energy in recent years thanks to a cleaner and more efficient combustion process compared to coal and oil. However, the presence of contaminants, such as carbon dioxide, means it must … Weiterlesen …

With the ocean covering approximately 72% of the earth’s surface, wave energy holds great potential to satisfy a significant percentage of the worldwide energy supply. The challenge is to reduce costs and improve the performance of wave energy systems. Now, Shun-Han … Weiterlesen …

Sono Motors announced that 10,000 reservations have already been placed throughout Europe more than one year before the start of production of their solar electric vehicle, Sion. The number of people interested in purchasing the first series production solar electric vehicle … Weiterlesen …

If it is possible to operate electric vehicles using only renewable energy, the CO2 emissions over the entire lifecycle fall by 70 % compared with combustion-engine vehicles. The same applies to fuel cell vehicles, which give rise to more emissions in … Weiterlesen …

Nidec‘s novel traction motor system E-Axle will be adopted by the Aion S e-car slated to appear on the Chinese market in May 2019. The company now presents a prototype of a new addition to its lineup of motors powering … Weiterlesen …
