Solar cells convert light into energy, but they can be inefficient and vulnerable to the environment, degrading with, ironically, too much light or other factors, including moisture and low temperature. An international research team has…

Growing consumption of energy and fossil fuels over four decades did not play a significant role in increasing life expectancy across 70 countries. New research, led by the University of Leeds, has quantified the importance of different…

Researchers at Linköping University have discovered a quantum phenomenon that influences the formation of free charges in organic solar cells. "If we can properly understand what's going on, we can increase the efficiency," says Olle…

Scientists have found a way in the laboratory to shorten the time it takes to create a key chemical used to synthesize a variety of medications, fertilizers and other important substances. The finding could make a number of industrial…

More than 2000 renewable energy facilities are built in areas of environmental significance and threaten the natural habitats of plant and animal species across the globe. A University of Queensland research team mapped the location of…

Terahertz (THz) waves fall between microwave and infrared radiation in the electromagnetic spectrum, oscillating at frequencies of between 100 billion and 30 trillion cycles per second. These waves are prized for their distinctive…

A team of scientists, led by the University of Bristol, has developed a new photosynthetic protein system enabling an enhanced and more sustainable approach to solar-powered technological devices. The initiative is part of a broader effort…

A professor at Duke University says that the way spilled milk spreads across the floor can explain why economic downturns regularly occur. In a paper published online on March 5 in the International Journal of Energy Research, Adrian Bejan,…

Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient's blood or serum. But current designs need a lot of DNA. In a new study, crumpling graphene makes it more than ten…

Fears that electric cars could actually increase carbon emissions are unfounded in almost all parts of the world, new research shows. Media reports have regularly questioned whether electric cars are really "greener" once emissions from…
