Skoltech scientists have studied the hydroxyl defects in LiFePO4, a widely used cathode material in commercial lithium-ion batteries, contributing to the overall understanding of the chemistry of this material. This work will help improve the LiFePO4 manufacturing process to avoid formation of adverse intrinsic structural defects which deteriorate its performance.
A breakthrough technology uses nanoscale sensors and fiber optics to measure water status just inside a leaf's surface, providing a tool to greatly advance our understanding of basic plant biology, and opening the door for breeding more drought-resistant crops.
Using a piece of magnet, researchers have designed a simple system that can control the movement of a small puddle of water, even when it's upside down. The new liquid manipulation strategy, described in the journal Cell Reports Physical Science on June 3, can have a wide range of applications including cleaning hard-to-reach environments or delivering small objects.

An interdisciplinary team of researchers at Wa...
Japanese researchers have developed and tested a prototype device -- wearable on the fingertips -- that incorporates the concept of 'light touch' to enhance the sense of balance. If widely implemented, the device should significantly reduce incidence of falls amongst seniors. The findings are published in the journal Scientific Reports on April 1.
