Scientists from the University of Groningen (the Netherlands) and the University of Würzburg (Germany) have investigated a simple biomimetic light-harvesting system using advanced spectroscopy combined with a microfluidic ...
When a metal is heated to a sufficiently high temperature, electrons can be ejected out from the surface in a process known as the thermionic emission, a process that is similar to the evaporation of water molecules from ...
A research team from Tokyo Institute of Technology (Tokyo Tech) and Kanazawa University has developed an ecofriendly device that uses solar energy to catalyze an electrochemical oxidation reaction with high efficiency.
Today's energy-hungry global society is struggling with how to mitigate the effects of man-made climate change, and under what conditions of voluntary/coercive adaptation. Present fossil fuel-free technologies appear inadequate/insufficient ...
A special ship designed to clean the oceans has harvested its first plastic from the Great Pacific Garbage Patch since setting sail from San Francisco last month, its Dutch inventor said Wednesday.
We're running out of water to grow food. Climate change, population growth and increasing demands on freshwater systems are straining agricultural water supplies.
Electrical engineers at Duke University have harnessed the power of machine learning to design dielectric (non-metal) metamaterials that absorb and emit specific frequencies of terahertz radiation. The design technique changed ...
Over the past few years, thermoelectric generators have become the focus of a growing number of studies, due to their ability to convert waste heat into electrical energy. Quantum dots, semiconductor crystals with distinctive ...
Few things on earth strike fear into the hearts of men more profoundly than hair loss. But reversing baldness could someday be as easy as wearing a hat, thanks to a noninvasive, low-cost hair-growth-stimulating technology ...
In a paper in Science Robotics, materials scientists from the UCLA Samueli School of Engineering describe a new design for a swimming robot that's both powered and steered by constant light.
