Purdue University researchers with an international team of collaborators have used a ‘thermal metamaterial’ to control the emission of radiation at high temperatures. The advance that could bring about devices able to efficiently harvest waste heat from power plants and factories. Generally, its known that about 50 to 60 percent of the energy generated in […]

University of Illinois at Urbana-Champaign researchers have identified the active form of an iron-containing catalyst for reducing oxygen gas, the element in a fuel cell that slows the process. Fuel cells have long held promise as power sources, but low efficiency from oxygen presence creates an obstacle to realizing the potential. The finding could help […]

Scientists from Forschungszentrum Juelich have developed the first complete and compact design for an artificial photosynthesis system. The team believes this is a decisive step towards applying the water splitting technology. The concept is flexible both with respect to the materials used and in particular, the size of the system. The researchers study and design […]

North Carolina State University researchers have developed a new design for harvesting body heat and converting it into electricity for use in wearable electronics. The experimental thermoelectric generator prototypes are lightweight, conform to the shape of the body, and can generate far more electricity than previous lightweight heat harvesting technologies. The researchers also believe they […]

Researchers in India at Jadavpur University in Koltata explored and found a way to recycle fish byproducts into an energy harvester for self-powered electronics. The basic premise behind the researchers’ work is simple: Fish scales contain collagen fibers that possess a piezoelectric property, which means that an electric charge is generated in response to applying […]
