Discovery Overturns 100 Year Old Fluid Flow Law
July 18, 2017 | 1 Comment
Imperial College London engineers have overturned a 100-year-old scientific law used to describe how fluid flows through rocks. Scientists from the College have used the Diamond Light Source facility in the UK to make 3D videos that show in more detail than ever before how fluids move through rock. For over one hundred years, engineers […]

Returning CO2 Back to Fuel With a New Catalyst
July 13, 2017 | 1 Comment
Okinawa Institute of Science and Technology (OIST) Coordination Chemistry and Catalysis Unit led by Prof. Julia Khusnutdinova have developed an efficient CO2 recycling catalyst based on an inexpensive and abundant metal: manganese. Manganese is the third most abundant metal in Earth’s crust after titanium and iron, and presents much lower toxicity as compared to many […]

Perovskite Photovoltaic Film Nears 20% Efficiency
July 12, 2017 | Leave a Comment
Georgia Institute of Technology researchers have devised a new low-temperature solution printing technique allows fabrication of high-efficiency perovskite solar cells. The technique uses large crystals intended to minimize current-robbing grain boundaries. The meniscus-assisted solution printing (MASP) technique boosts power conversion efficiencies to nearly 20 percent by controlling crystal size and orientation. The process, which uses […]

University of Texas researchers and Seoul National University have designed a new manganese and sodium ion based material that might replace many lithium ion batteries. The new chemistry offers a potentially lower-cost, more eco-friendly option to energize next generation devices and electric cars. In the battle of the batteries, lithium-ion technology is the reigning champion, […]

Stretchable Compressible Wearable Supercapacitors
July 6, 2017 | 1 Comment
Chinese scientists have introduced an extraordinarily stretchable and compressible polyelectrolyte. The new electrolyte when combined with carbon nanotube composite paper electrodes, forms a supercapacitor that can be stretched to 1000 percent in length and compressed to 50 percent in thickness without gaining and not losing capacity. The potential for flexible, wearable electronics that require equally […]
