Time Scale Stretching For Improving Prediction Of Extreme Events

A technique currently applied in the field of photonics could help predict rogue wave events on the ocean surface, along with other extreme natural phenomena. Stretching time scales to explore extreme events in nature is possible, according to a team from the Institut FEMTO-ST, which used an innovative measurement technique enabling the capture of such […]

Femtosecond Laser Pulse Control Of Electron Microscope Nanotips

A method of controlling electron emissions with higher precision than ever before has been developed by researchers at Vienna University of Technology, together with colleagues from the FAU Erlangen-N├╝rnberg in Germany. In an electron microscope, electrons are emitted by pointy metal tips, so they can be steered and controlled with high precision. Recently, such metal […]

Light Can Mold and Move Hydrogels

Using only light, hydrogels and be moved around and re-shaped, computer simulations done at the University of Pittsburgh have shown. Animals like the octopus and cuttlefish that transform their shape depending on their environment have long been the subject of interest for researchers. This is because mimicking similar biological responses in non-living organisms would have […]
