New sensor detects chemicals that impair thyroid gland (23/01/2024)
In a study conducted at the
University of Twente, Technion-Israel Institute of Technology and the Open
University of Israel, researchers have developed a novel approach to address
the environmental challenges posed by perchlorate salts, which have been
identified as persistent pollutants with potential impacts on human health.
Black phosphorus propels spintronics with exceptional anisotropic spin transport (21/01/2024)
With modern electronic devices
approaching the limits of Moore's law and the ongoing challenge of power
dissipation in integrated circuit design, there is a need to explore alternative
technologies beyond traditional electronics. Spintronics represents one such
approach that could solve these issues and offer the potential for realizing
lower-power devices.
New carbon-based tunable metasurface absorber paves the way for advanced terahertz technology (21/01/2024)
Working in the terahertz (THz)
range offers unique opportunities in various applications, including biomedical
imaging, telecommunications, and advanced sensing systems. However, because of
the unique properties of electromagnetic waves in the 0.1 to 10 THz range, it
has proven difficult to develop high-performance components that showcase the
true potential of THz technology. Even the design of basic and essential
elements like filters and absorbers remains a substantial challenge.
Scientists compute with light inside hair-thin optical fiber (21/01/2024)
Scientists at Heriot-Watt
University in Edinburgh, Scotland, have found a powerful new way to program
optical circuits that are critical to the delivery of future technologies such
as unhackable communications networks and ultrafast quantum computers.
New research sheds light on how non-spherical atmospheric particles behave (21/01/2024)
The atmosphere contains many tiny
solid particles. Scientists from the Max Planck Institute for Dynamics and
Self-Organization (MPI-DS) and the University of Göttingen, in collaboration
with the Centre National de la Recherche Scientifique (CNRS) in France and the
University of Gothenburg, Sweden, now studied how such non-spherical particles
settle in the air.
Creating a new, sustainable plastic using physics (21/01/2024)
For the past three years, Ph.D.
candidate Sophie van Lange has been dedicated to one clear goal: producing
plastic that is both hard and sustainable. The plastics we use today are either
recyclable or strong and hard—not both. Van Lange stepped away from traditional
chemical approaches to produce plastic and developed a completely new method to
create durable and reusable plastic in a completely new way. The trick?
Physical forces.
Machine learning models teach each other to identify molecular properties (21/01/2024)
Biomedical engineers at Duke
University have developed a new method to improve the effectiveness of machine
learning models. By pairing two machine learning models, one to gather data and
one to analyze it, researchers can circumvent limitations of the technology
without sacrificing accuracy.
Reaching the quantum ground state of sound in waveguides: Scientists move a step closer (21/01/2024)
A team of scientists at the Max
Planck Institute for the Science of Light led by Dr. Birgit Stiller has
succeeded in cooling traveling sound waves in waveguides considerably further
than has previously been possible using laser light. This achievement represents
a significant move towards the ultimate goal of reaching the quantum ground
state of sound in waveguides.
New material opens up possibility of converting water pollutants into hydrogen gas (20/01/2024)
WPI Researchers have developed a
material to remove urea from water and potentially convert it into hydrogen
gas. By building these materials of nickel and cobalt atoms with carefully
tailored electronic structures, the group has unlocked the potential to enable
these transition metal oxides and hydroxides to selectively oxidize urea in an
electrochemical reaction.
"Dirt-powered fuel cell" draws near-limitless energy from soil (16/01/2024)
A Northwestern University team has demonstrated a remarkable
new way to generate electricity, with a paperback-sized device that nestles in
soil and harvests power created as microbes break down dirt – for as long as
there's carbon in the soil.
