Ten Nanometers That Keep the Battery in Check
A calcium sodium phosphate layer just ten nanometers thick stopped O3 sodium cathode cracking — smooth surface after 300 cycles. Cheap compounds instead of exotic materials.
A battery that falls from a tree. How a dead leaf will power the Internet of Things
Of the two hundred sensors in the Oregon forests, seventeen are working - the batteries died after eight months. A dead leaf coated with a gel polymer is expected to power some of the 29 billion IoT devices.
A robot that feels what it is holding
The electronic skin from Harbin Institute combines an electrostatic and triboelectric sensor. The robot recognizes shape (94.3%) and material (91.7%) in a second. Polish potential: ASTOR, FANUC Poland, NCBR PLN 45 million.
An atom shifted by a fraction of a picometer: new ptychography reaches where convention fails
Researchers from Tsinghua University have exceeded the electron ptychography thickness threshold by three times, achieving an atomic position precision of 0.39 pm in 85-nanometer silicon. The road to atomic chip quality control.
A binder that spoils the cell. New interface chemistry could unlock perovskites
Phosphonic acids destroyed the perovskites from the inside. The new binder extends module life >22% to T90 3000h and brings silicon/perovskite tandems closer to production.
