Reconfigurable metasurfaces provide nanoscale light control

Researchers have designed electromechanically reconfigurable ultrathin optical elements that can be controlled and programmed on a pixel-by-pixel level. These versatile metasurfaces could offer a new chip-based way to achieve ...

Scientists find a way to make pultrusion faster

A research team from the Skoltech Center for Design, Manufacturing and Materials (CDMM) has studied the effects of processing additives—aluminum hydroxide and zinc stearate—on the polymerization kinetics of thermosets ...

How insect wings withstand collisions without breaking

About once a second wings of foraging bees collide with small obstacles such as flowers, leaves or branches during flight without suffering major long-term damage. At the same time, they withstand aerodynamic loads effortlessly—yet ...

Researchers analyse how 3-D printed metals fracture

3-D-printed metals have been used since the 1980s to produce a wide range of parts for various industries. These materials often have tiny pores inside them (around dozens of micrometers in size), which can get bigger when ...
