Optomechanics simulates graphene lattices

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 — called carbon-based electrochemical catalysis — 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...
