Lens-less microscope-on-a-chip

A diffuser moved randomly over a sample can be the basis of a computational microscope, according to researchers at the University of Connecticut. Lensless computational microscopy is not new – Horiba and French research lab Leti revealed one a couple of years ago. A disadvantage is that a lot of computing power is needed to reverse-engineer diffraction patterns ...

Keeping Pb inside solar cells and out of the environment

Perovskite solar cells show great potential for low-cost large-scale generation, but all the best ones contain lead (Pb), adding an environmental risk if that are to be widely deployed. Now researchers at Northern Illinois University with the US National Renewable Energy Laboratory have created a self-sequestering perovskite solar cell – one that binds up over ...

Ultrasound could make metallic lithium batteries safe, and more

Metallic lithium batteries offer far more performance than lithium-ion cells, and are so dangerous that no one uses them. One of the problems is dendrite growth – long thin crystals of lithium grow from the electrodes – that can short the cell and lead to self-destruction. Now the University of California San Diego has found ...
