An international research team including Los Alamos National Laboratory and Tel Aviv University has developed a unique, mechanical metamaterial that, like a computer following instructions, can remember the order of actions performed on it. Named Chaco, after the archaeological site in northern New Mexico, the new metamaterial offers a route to applications in memory storage, robotics, and even mechanical computing.
From the rain drops rolling down your window, to the fluid running through a COVID rapid test, we cannot go a day without observing the world of fluid dynamics. Naturally, how liquids traverse across, and through, surfaces is a heavily researched subject, where new discoveries can have profound effects in the fields of energy conversion technology, electronics cooling, biosensors, and micro-/nano-fabrications.
The shimmering of butterfly wings in bright colors does not emerge from pigments. Rather, photonic crystals are responsible for the play of colors. Their periodic nanostructure allows light at certain wavelengths to pass through while reflecting other wavelengths. This causes the wing scales, which are in fact transparent, to appear so magnificently colored.
The Buccino Leadership Institute presents Ideas & Trends (2024) Nanotechnology: The Three Lenses — Past, Present and Future.
Structural and dynamic DNA nanosciences offer unique tools for engineering bottom–up synthetic cells. This Review provides a holistic overview for using DNA as a structural material, for designing functional entities, and for information-processing circuits for adaptive and interactive behaviour.
Proteins are molecular machines, with flexible pieces and moving parts. Understanding how these parts move helps scientists unravel the function a protein plays in living things—and potentially how to change its effects. Biochemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and colleagues at DOE’s Pacific Northwest National Laboratory (PNNL) have published a new example of how one such molecular machine works.
Researchers develop a precise method for patterning gold nanoparticles on surfaces using DNA origami and electron beam lithography, enabling tunable plasmonic metasurfaces.
Discover bottom-up nanotechnology: precision construction of nanostructures for breakthroughs in medicine, electronics, and beyond.
Prof. Wang Qi’s research group from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has synthesized iron-and nitrogen-co-doped CoFeP-N nanowires for high-efficiency electrocatalytic water splitting.
Safe and high-quality fertility preservation is of growing significance for women in clinical trials. Current primary methods for cryopreserving human oocytes are slow freezing and vitrification, but existing techniques pose risks of biochemical toxicity and are restricted in large-scale clinical practice.
