Beyond the lithium ion - a significant step toward a better performing battery
Researchers have shown they can replace the lithium ions, each of which carries a single positive charge, with magnesium ions, which have a plus-two charge, in battery-like chemical reactions, using an electrode with a structure like those in many of today's devices.
Optical resonance-based biosensors designed for medical applications
Besides achieving greater resolution and sensitivity, the materials used in these new devices are much cheaper and more versatile than the ones used in current technologies (mainly gold and noble metals) so they could offer a potential alternative in the design of biomedical sensors.
Framework compounds: metal-organic transformations
The mechanosynthesis of cage compounds suitable for storing gases can be monitored in real-time with the help of X-ray powder diffraction.
Engineer improves rechargeable batteries with MoS2 nano 'sandwich'
Molybdenum disulfide sheets - which are 'sandwiches' of one molybdenum atom between two sulfur atoms - may improve rechargeable lithium-ion batteries, according to the latest research.
