New green technology from UMass Amherst generates electricity ‘out of thin air’

Scientists at the University of Massachusetts Amherst have developed a device that uses a natural protein to create electricity from moisture in the air, a new technology they say could have significant implications for the future of renewable energy, climate change and in the future of medicine. As reported today in Nature, the laboratories of electrical … Read more New green technology from UMass Amherst generates electricity ‘out of thin air’

New droplet-based electricity generator: A drop of water generates 140V power, lighting up 100 LED bulbs

Generating electricity from raindrops efficiently has gone one step further. A research team led by scientists from the City University of Hong Kong (CityU) has recently developed a droplet-based energy generator (DEG), featured with a field-effect transistor (FET)-like structure that allows for high energy-conversion efficiency and instantaneous power density increased by thousands times compared to its counterparts … Read more New droplet-based electricity generator: A drop of water generates 140V power, lighting up 100 LED bulbs

Instant hydrogen production for powering fuel cells

Since the Industrial Revolution, the environmental impacts of energy have posed a concern. Recently, this has driven researchers to search for viable options for clean and renewable energy sources. Due to its affordability and environmental friendliness, hydrogen is a feasible alternative to fossil fuels for energy applications. However, due to its low density, hydrogen is … Read more Instant hydrogen production for powering fuel cells

Global aromaticity at the nanoscale

The concept of aromaticity is central to organic chemistry and it is widely used to interpret the structure and reactivity of small molecules. This article shows that global aromaticity can arise in molecular rings as large as proteins. Hückel’s rule was formulated in 1931 by considering molecules with up to 6 π-electrons. A new Oxford’s … Read more Global aromaticity at the nanoscale

Infrared detection of aliphatic organics on a cometary nucleus

An accurate refinement of the quality of the data on the surface composition of the nucleus of the comet 67P Churyumov Gerasimenko collected by the Italian spectrometer VIRTIS, on board the European space mission Rosetta, has allowed to identify, the first time for a comet, clear traces of aliphatic organic compounds, chains of carbon and … Read more Infrared detection of aliphatic organics on a cometary nucleus

Australian desalination plant attracts fish

With growing populations and climate uncertainty, water security is a global concern. Many nations operate desalination plants, which remove salt from seawater to make it drinkable. These facilities typically discharge excess salt as hypersaline brine back into the ocean, with uncertain ecological effects. Now, researchers in Environmental Science & Technology report that a large desalination plant in … Read more Australian desalination plant attracts fish

Chemists glimpse the fleeting ‘transition state’ of a reaction

During a chemical reaction, the molecules involved in the reaction gain energy until they reach a “point of no return” known as a transition state. Until now, no one has glimpsed this state, as it lasts for only a few femtoseconds (quadrillionths of a second). However, chemists at MIT, Argonne National Laboratory, and several other … Read more Chemists glimpse the fleeting ‘transition state’ of a reaction

Oil catching sponge

The remediation of oil field effluents is a global challenge. For example, in the United States, over 15 billion barrels of oil-contaminated wastewater produced each year. Cherukupally and Sun et al. report an innovative surface engineered sponge that combines surface chemistry, pH-responsive surface charge, and multiscale roughness to enhance the surface wetting of the sponge. [rand_post] Their … Read more Oil catching sponge

KAUST’s plastic biosensor finds sweet success

An electronic biosensor powered using the glucose in bodily fluids has been developed by KAUST researchers. The device pairs an electron-transporting polymer with an enzyme that extracts electrons from its reaction with glucose to drive its circuitry. The plastic biosensor could act as a continuous monitor of key health indicators, such as blood sugar levels … Read more KAUST’s plastic biosensor finds sweet success

New way to make biomedical devices from silk yields better products with tunable qualities

Researchers led by engineers at Tufts University have developed a novel, significantly more efficient fabrication method for silk that allows them to heat and mold the material into solid forms for a wide range of applications, including medical devices. The end products have superior strength compared to other materials, have physical properties that can be … Read more New way to make biomedical devices from silk yields better products with tunable qualities
