Molecular coating enhances organic solar cells

(King Abdullah University of Science & Technology (KAUST)) A single-molecule layer that helps to channel electrical charge into an electrode can outperform the best conventional material.

Geologist identifies new form of quasicrystal

(University of Massachusetts Lowell) A UMass Lowell geologist is among the researchers who have discovered a new type of manmade quasicrystal created by the first test blast of an atomic bomb.

New form of silicon could enable next-gen electronic and energy devices

(Carnegie Institution for Science) A team led by Carnegie’s Thomas Shiell and Timothy Strobel developed a new method for synthesizing a novel crystalline form of silicon with a hexagonal structure that could potentially be used to create next-generation electronic and energy devices with enhanced properties that exceed those of the “normal” cubic form of silicon used today.

A non-invasive procedure allows obtaining archaeological information without excavating

(Universitat Pompeu Fabra – Barcelona) An international archaeological study, led by researchers from the Culture and Socio-Ecological Dynamics (CaSEs) research group, has advanced in the understanding and preservation of archaeological sites and in improving their analysis, thanks to the application of pXRF (portable X-ray fluorescence analysis) to anthropogenic sediments in Africa. It is a rapid, inexpensive, non-invasive procedure, which enables generating an additional archaeological record from the anthropogenic deposit by analysing chemical elements, combined with geostatistics.

World’s First Fully-Recyclable Electronic Transistor Produced By 3D Printers at Duke University

Engineers at Duke University have developed the world’s first fully recyclable printed electronics. Their recycling process recovers nearly 100% of the materials used—and preserves most of their performance capabilities for reuse. By demonstrating a crucial and relatively complex computer component—the transistor—created with three carbon-based inks, the researchers hope to inspire a new generation of recyclable […]

Researchers Boost Performance of Solar Cells By Using Human Hair From a Barbershop

Researchers have used carbon dots, created from human hair waste sourced from a barbershop, to create a kind of ‘armor’ to improve the performance of cutting-edge solar technology. In a study, the researchers led by Professor Hongxia Wang in collaboration with Associate Professor Prashant Sonar of QUT’s Centre for Materials Science showed the carbon nanodots could […]

Transforming atmospheric carbon into industrially useful materials

(Salk Institute) Plants are unparalleled in their ability to capture carbon from the air, but this benefit is temporary. Researchers have proposed a more permanent, and even useful, fate for this captured carbon by turning plants into a valuable industrial material called silicon carbide (SiC). A new study from Salk scientists quantifies this process with more detail than ever before.

Florida Inventors Hall of Fame announces 2021 inductees

(University of South Florida (USF Innovation)) Seven Florida Inventors whose discoveries are saving lives, transforming the environment, and creating new technologies are named as 2021 Inductees to the Florida Inventors Hall of Fame. Among them are Dean Kamen, often referred to as the modern Thomas Edison due to the scope of his trailblazing inventions, including the Segway®; and Mark Dean, who holds three patents for the original IBM PC and is co-inventor of the ISA bus which revolutionized modern computing.

China’s Solar Dominance Presents Biden With Human Rights Dilemma

WASHINGTON — President Biden has repeatedly pledged to work with China on issues like climate change while challenging Beijing on human rights and unfair trade practices. But those goals are now coming into conflict in the global solar sector, presenting…

Transparent nanolayers for more solar power

(Forschungszentrum Juelich) There is no cheaper way to generate electricity today than with the sun. Solar cells available on the market based on crystalline silicon make this possible with efficiencies of up to 23 percent. With even higher efficiencies of more than 26 percent, costs could fall further. An international working group led by photovoltaics researchers from Forschungszentrum Jülich now plan to reach this goal with a nanostructured, transparent material for the front of solar cells.
