Researchers 3D print a miniature vacuum pump

Apr 25, 2023 (Nanowerk News) Mass spectrometers are extremely precise chemical analyzers that have many applications, from evaluating the safety of drinking water to detecting toxins in a patient’s blood. But building an inexpensive, portable mass spectrometer that could be deployed in remote locations remains a challenge, partly due to...

Circuit boards from renewable raw materials

Apr 25, 2023 (Nanowerk News) For many years, Thomas Geiger has been conducting research in the field of cellulose fibrils – fine fibers that can be produced from wood pulp or agricultural waste, for example. Cellulose fibrils hold great potential for sustainable production and the decarbonization of industry: they grow...

Expanding plasmonic enhancement limits with hexagonal boron nitride

Apr 24, 2023 (Nanowerk News) A study spearheaded by Professor Yang Liangbao from the Hefei Institutes of Physical Science at the Chinese Academy of Sciences discovered that hexagonal boron nitride (h-BN) effectively inhibits electron tunneling, thereby extending the ultimate plasmonic enhancement boundaries in single-atom-layer gaps. This breakthrough offers valuable insights...

Greener batteries

Apr 24, 2023 (Nanowerk News) Our modern rechargeable batteries, such as lithium-ion batteries, are anything but sustainable. One alternative is organic batteries with redox-organic electrode materials (OEMs), which can be synthesized from natural “green” materials. In the journal Angewandte Chemie ("A Recyclable and Scalable High-Capacity Organic Battery"), a Chinese team...
