A single atom can change the directional profile of the light emitted in scanning tunneling microscopes (07/11/2024)
Researchers from Madrid explain a
phenomenon that allows the direction of light emission to be controlled at the
atomic scale. The paper provides a detailed explanation of how the profile of
the light collected in a scanning tunneling microscope (STM) experiments
changes when the tip is placed on an atomic step.
Researchers develop high-quality nanomechanical resonators with built-in piezoelectricity (07/11/2024)
Researchers at Chalmers
University of Technology in Sweden and at the University of Magdeburg in
Germany have developed a novel type of nanomechanical resonator that combines
two important features: high mechanical quality and piezoelectricity. This development
could open doors to new possibilities in quantum sensing technologies.
Sustainable hydrophobic cellulose shows potential for replacing petroleum-related products (07/11/2024)
A recent study has aimed to
create hydrophobic paper by exploiting the mechanical properties and water
resistance of cellulose nanofibers, and so produce a sustainable,
high-performance material suitable for packaging and biomedical devices. This
involved a supramolecular approach, i.e., combining short chains of proteins
(peptide sequences) that do not chemically modify the cellulose nanofibers.
Sustainable hydrophobic paper may one day replace petroleum-related products.
Successful demonstration of a commercial cryogenic radio frequency power sensor paves way for quantum computing (07/11/2024)
Radio frequency (RF) and
microwave power measurements are widely used to support applications across
space, defense, and communication. These precise measurements enable engineers
to accurately characterize waveforms, components, circuits, and systems.

Queen Mary University of London
researchers have developed new nanocomposite films using starch instead of
petroleum-based materials, marking a significant advancement in the field of
sustainable electronics.
New electrochemical water splitting method offers fast, sustainable method for hydrogen production (29/10/2024)
Under the leadership of Prof. Dr.
Francesco Ciucci from the University of Bayreuth, a German–Chinese research
team has developed a new method for the electrochemical splitting of water.
This not only accelerates the production of hydrogen for technology and
industry but also makes it more sustainable. The researchers published their
findings in Nature Nanotechnology.
Graphene-based memristors move a step closer to benefiting next-generation computing (29/10/2024)
Researchers from Queen Mary
University of London and Paragraf Limited have demonstrated a significant step
forward in the development of graphene-based memristors and unlocking their
potential for use in future computing systems and artificial intelligence (AI).
A quantum material could be the future of high-energy X-ray imaging and particle detection (13/10/2024)
Scintillators are detectors that
make high-energy X-rays or particles visible through flashes of light to form
an image. Their many applications include particle physics, medical imaging,
X-ray security and more.
Engineering perovskite materials at the atomic level paves way for new lasers, LEDs (13/10/2024)
Researchers have developed and
demonstrated a technique that allows them to engineer a class of materials
called layered hybrid perovskites (LHPs) down to the atomic level, which
dictates precisely how the materials convert electrical charge into light. The
technique opens the door to engineering materials tailored for use in
next-generation printed LEDs and lasers—and holds promise for engineering other
materials for use in photovoltaic devices.
Scientists use light to visualize magnetic domains in quantum materials (13/10/2024)
When something draws us in like a
magnet, we take a closer look. When magnets draw in physicists, they take a
quantum look. Scientists from Osaka Metropolitan University and the University
of Tokyo have successfully used light to visualize tiny magnetic regions, known
as magnetic domains, in a specialized quantum material. Their study was published in Physical
Review Letters.
