Sep 01, 2022 (Nanowerk News) Composite particles with submicron sizes can be produced by irradiating a suspension of nanoparticles with a laser beam. Violent physical and chemical processes take place during irradiation, many of which have to date been poorly understood. Recently completed experiments, carried out at the Institute of...
Better metal oxides to boost the green credentials of many energy applications
Sep 01, 2022 (Nanowerk News) Researchers have solved a key hurdle in greener manufacturing, carbon capture, energy storage and gas purification – using metal oxides. Metal oxides are compounds that play a crucial role in processes that reduce carbon dioxide (CO2) emissions. These processes include carbon capture, utilisation and storage...
A sustainable battery with a biodegradable electrolyte made from crab shells
Sep 01, 2022 (Nanowerk News) Accelerating demand for renewable energy and electric vehicles is sparking a high demand for the batteries that store generated energy and power engines. But the batteries behind these sustainability solutions aren’t always sustainable themselves. In a paper in the journal Matter ("A sustainable chitosan-zinc electrolyte...
Green adhesives made from whey
Sep 01, 2022 (Nanowerk News) Every day, large quantities of whey are produced as a by-product by the dairy industry. In Germany alone, this amounts to 12.6 million tons a year. For each kilogram of cheese, for example, 9 kilograms of whey are produced. Some of this is processed further,...
Advancing new technologies to halt bleeding
Sep 01, 2022 (Nanowerk News) The research arm of the U. S. Army has awarded Case Western Reserve University blood surrogate pioneer Anirban Sen Gupta a four-year, $2.5 million grant to advance and optimize his latest nanotechnology to stop bleeding from battlefield injuries.

Soaking up the sun with artificial intelligence
Sep 01, 2022 (Nanowerk News) The sun continuously transmits trillions of watts of energy to the Earth. It will be doing so for billions more years. Yet, we have only just begun tapping into that abundant, renewable source of energy at affordable cost. Solar absorbers are a material used to...
Algorithms for manufacturing mRNA-based pharmaceuticals
Sep 01, 2022 (Nanowerk News) Back in 2019, BioNTech was far from a household name. Nowadays, however, the pharmaceutical company from Mainz is world-famous for developing and producing Comirnaty©, a COVID-19 vaccine. The company’s original aim was to develop personalized mRNA-based treatments to fight cancer – a goal that it...
Using nanopores to detect epigenetic changes faster
Aug 31, 2022 (Nanowerk News) Changes known as epigenetic modifications play an important role in cancer development, among other things. Being able to analyze them quickly and reliably could, for example, contribute significantly to the further development of personalized therapy. A research team from the Institute of Physiology at the...
Simple technique ushers in long-sought class of semiconductors
Aug 31, 2022 (Nanowerk News) Breakthroughs in modern microelectronics depend on understanding and manipulating the movement of electrons in metal. Reducing the thickness of metal sheets to the order of nanometers can enable exquisite control over how the metal's electrons move. In so doing, one can impart properties that aren't...
