Dec 22, 2022 (Nanowerk News) The precise control of micro-mechanical oscillators is fundamental to many contemporary technologies, from sensing and timing to radiofrequency filters in smartphones. Over the past decade, quantum control of mechanical systems has been firmly established with atoms, molecules, and ions in the first wave of development...
Where we are and where we need to go
Dec 22, 2022 (Nanowerk News) The abundant carbon on Earth might offer a rich, renewable resource for clean, sustainable energy. The technology â called carbon-based electrochemical catalysis â that could make green energy conversion possible exists, according to an international collaboration investigating recent advancements, but is not ready for broad application....
Nanoantennas directing a bright future
Dec 21, 2022 (Nanowerk News) White LEDs may soon be dethroned as the world's go-to light source by an alternative with a much better sense of direction. As a next-generation optical control technology, a photonic crystal or nanoantenna is a two-dimensional structure in which nano-sized particles are arranged periodically on a substrate. Upon irradiation,...
The next milestones in generating artificial organs
Dec 21, 2022 (Nanowerk News) What is the ultimate goal of research using human pluripotent stem cells? In the context of regenerative medicine, I think it’s to recreate whole, replaceable organs in a laboratory setting. Transplanting these organoids could improve many treatment options. For instance, in the case of kidney...
Artificial DNA kills cancer
Dec 21, 2022 (Nanowerk News) Researchers at the University of Tokyo have used artificial DNA to target and kill cancer cells in a completely new way. The method was effective in lab tests against human cervical cancer- and breast cancer-derived cells, and against malignant melanoma cells from mice (JACS, "Oncolytic...
A rough start can lead to a strong bond
Dec 21, 2022 (Nanowerk News) The manufacturing industry is constantly on the lookout for more efficient manufacturing materials, but most new methods to develop such materials created in the lab are not suited for industrial-scale use. Now, investigators from The Institute of Industrial Science at The University of Tokyo have...
How optical microscopes allow detailed investigations of nanoparticles
Dec 21, 2022 (Nanowerk News) Nanoparticles - i.e. small particles with a size in the range of a few tens to hundreds of billionths of a meter - are a wide-ranging field of research. For example, they make the latest biomedical applications possible by acting as a kind of container...
Ammonium is the secret ingredient in stable, efficient and scalable perovskite solar cells
Dec 21, 2022 (Nanowerk News) A new pathway to creating durable, efficient perovskite photovoltaics at industrial scale has been demonstrated through the first effective use of lead acetate as a precursor in making formamidinium-caesium perovskite solar cells. Members of Exciton Science, based at Monash University, were able to create perovskite...
Making the unimaginable possible in materials discovery
Dec 21, 2022 (Nanowerk News) Scientists find way to make new materials for batteries, magnets and microelectronics. The world’s best artists can take a handful of differently colored paints and create a museum-worthy canvas that looks like nothing else. They do so by drawing upon inspiration, knowledge of what’s been...
Infinite creaminess – the disintegration of drops has no limit
Dec 20, 2022 (Nanowerk News) New computer simulations can go where experiments reach their limits. Scientists from the Center of Applied Space Technology and Microgravity (ZARM) at the University of Bremen have developed a computer code that enables accurate predictions of the disintegration of droplets in turbulent flows. Surprisingly it...
