Towards stable, sustained Raman imaging of large samples at the nanoscale
Jul 17, 2022 (SPX)
However, since light is a wave, optical microscopes are unable to resolve distances less than half the wavelength of the light incident on the sample. This is k...
A mirror tracks a tiny particle
Jun 30, 2022 (SPX)
"Typically, we measure a nanoparticle's position with a technique called optical interferometry, in which part of the light emitted by a nanoparticle is compare...
New silicon nanowires can really take the heat
May 18, 2022 (SPX)
Electronic devices powered by microchips that efficiently dissipate heat would in turn consume less energy - an improvement that could help mitigate the consump...
Cooling speeds up electrons in bacterial nanowires
May 12, 2022 (SPX)
Yale University researchers have been studying ways to enhance this natural electrical conductivity within nanowires 1/100,000th width of a human hair by identi...
Seeing more deeply into nanomaterials
Apr 14, 2022 (SPX)
This has been a complex challenge that researchers from Columbia Engineering and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have overc...
Atom by atom: building precise smaller nanoparticles with templates
Mar 07, 2022 (SPX)
Recently, quasi-sub-nanomaterials, which are about 1-3 nm in scale have attracted attention because they have a dual nature-they can be regarded as nanoparticle...
Ring my string: Building silicon nano-strings
Mar 01, 2022 (SPX)
This effect, known as 'dissipation dilution', has been exploited to develop mechanical devices for quantum technologies, where engineered, tensioned nanostrings...
Nanotube films open up new prospects for electronics
Feb 11, 2022 (SPX)
Carbon nanomaterials form an extensive class of compounds that includes graphene, fullerenes, nanotubes, nanofibers, and more. Although the physical properties ...
Using the universe's coldest material to measure the world's tiniest magnetic fields
Feb 09, 2022 (SPX)
Some magnetic fields of great interest, for example those produced by the brain, are extraordinarily weak, a billion times weaker than the field of the Earth, a...
Self-assembling and complex, nanoscale mesocrystals can be tuned for a variety of uses
Feb 09, 2022 (SPX)
Mesocrystals are nanoparticles with identical size, shape and crystallographic orientation, and they can be used as building blocks to create artificial nanostr...
Speeding through nanowire
Feb 08, 2022 (SPX)
A team of researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the TU Dresden and NaMLab has now succeeded in experimentally demonstrating that ele...
Columns designed from nanographenes
Feb 08, 2022 (SPX)
Large, single-layer PAH molecules - often referred to as nanographenes - are well researched. In contrast, little is known about PAHs arranged into columnar mul...
Discovery unravels how atomic vibrations emerge in nanomaterials
Feb 07, 2022 (SPX)
Now there is definitive, experimental proof that at the nanoscale, the notion of multiple thin materials with distinct vibrations no longer holds. If the materi...
Simulations shed significant light on Janus particles
Jan 26, 2022 (SPX)
The resulting chemical asymmetry led to the discovery of new and unusual molecular properties, making Janus particles relevant to a wide range of applications, ...
The secret of ultralight but stiff sandwich nanotubes
Oct 27, 2021 (SPX)
Modelling by materials scientists from the University of Groningen (The Netherlands) revealed how this could happen. In a paper published on 25 October in Natur...
AFRL Nano Team takes lead in building stronger ties with India
Oct 25, 2021 (SPX)
Nanomaterials are thin - about 1/100,000th of the thickness of a human hair. AFRL and its partners are harnessing nanomaterials' unique optical, magnetic, elect...
Striking Gold: A Pathway to Stable, High-Activity Catalysts from Gold Nanoclusters
Aug 16, 2021 (SPX)
Catalysts, which help drive reactions, are ubiquitous, whether as an enzyme in the body that digests food or the catalytic converter in the car that breaks down...
Tracking the movement of a single nanoparticle
Jul 28, 2021 (SPX)
The nanoparticle tracking analysis (NTA) system is the most commonly used nanoparticle quantification method in the world. It is a method that observes and trac...
Researchers demonstrate technique for recycling nanowires in electronics
Jul 28, 2021 (SPX)
"There is a lot of interest in recycling electronic materials because we want to both reduce electronic waste and maximize the use we get out of rare or costly ...
Custom-made MIT tool probes materials at the nanoscale
Jul 14, 2021 (SPX)
"Modern materials research has greatly benefited from advanced experimental tools," says Long Ju, an assistant professor in the Department of Physics. Ju is an ...
