New design points a path to the ‘ultimate’ battery
Researchers have successfully demonstrated how several of the problems impeding the practical development of the so-called ‘ultimate’ battery could be overcome.
Molecular nanoribbons as electronic highways
Physicists have developed a method to synthesize a unique and novel type of material which resembles a graphene nanoribbon but in molecular form. This material could be important for the further development of organic solar cells.
First superconducting graphene created by researchers
Graphene, the ultra-thin, ultra-strong material made from a single layer of carbon atoms, just got a little more extreme. Physicists have been able to create the first ever superconducting graphene sample by coating it with lithium atoms.
New battery shuts down at high temperatures, restarts when it cools
The first lithium-ion battery has been developed that shuts down before overheating, then restarts immediately when the temperature cools. The new technology could prevent the kind of fires that have prompted recalls and bans on a wide range of battery-powered devices, from computers to hoverboards.

Using sunlight to recharge the cooling system of trailer containers
A group of scientists has replaced diesel with kinetic energy, saving up to 20 thousand liters of fuel annually, they say, adding that this includes a series of energetically self-sustained boxes for the transport of perishable goods, with a cooling system that replaced the use of diesel with sunlight and kinetic energy.
Graphene as a front contact for silicon-perovskite tandem solar cells
A team of researchers has developed an elegant process for coating fragile perovskite layers with graphene for the first time. Subsequent measurements show that the graphene layer is an ideal front contact in several respects.
‘Diamonds from the sky’ approach turns CO2 into valuable products
Finding a technology to shift carbon dioxide, the most abundant anthropogenic greenhouse gas, from a climate change problem to a valuable commodity has long been a dream. Now, a team of chemists says they have developed a technology to economically convert atmospheric CO2 directly into highly valued carbon nanofibers for industrial and consumer products.
