Researchers from Skoltech and MEPhI have devised a laser polishing technique that effectively removes both surface roughness and subsurface pores in intricately shaped metal parts manufactured with a 3D printer. Described in Optics & Laser […]

If COVID-19 had taught us anything it surely must be that poorly ventilated buildings can be a health hazard. Yet due to a weakness in current rules they continue to be built.This post was originally […]

Engineering researchers have created new high-power electronic devices that are more energy efficient than previous technologies. The devices are made possible by a unique technique for “doping” gallium nitride (GaN) in a controlled way.This post […]

People have been fascinated by bird flight for centuries, but exactly how birds can be so agile in the air remains mysterious. A new study, published Sept. 5 in Proceedings of the National Academy of […]

The physics of walking for multi-legged animals and robots is simpler than previously thought. That is the finding described by a team of roboticists, physicists and biologists in the Sept. 5 issue of the Proceedings […]

Student teams are an underappreciated resource in much of the scientific community. Joining a team working toward a goal while at university, whether for racing solar-powered cars or digging fish ponds in Africa, is an […]

What goes on inside planets like Neptune and Uranus? To find out, an international team headed by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the University of Rostock and France’s École Polytechnique conducted a novel experiment. They fired […]

Clean freshwater is critical for sustaining human life. However, 1.1 billion people lack access to it worldwide. Desalination represents an increasingly popular way of addressing this.This post was originally published on this site

The rising price and low availability of raw materials, especially silver, are leading to higher costs in producing photovoltaic modules. Fraunhofer researchers have developed an electroplating process that involves substituting silver, an expensive precious metal, […]
