Using nickel foam to enhance the performance of lithium-sulfur batteries (02/10/2023)
Lithium-sulfur (Li-S) batteries are considered important devices for powering movable equipment, but there are still some challenges that limit their application, such as how to obtain a cathode for high sulfides absorption and rapidly conversion.
Coatings made from a wood by-product can keep our glasses and windshields clear (02/10/2023)
Researchers have developed a way to turn a waste material from wood into a bio-based transparent film that can be used for anti-fogging or anti-reflective coatings on glasses or vehicle windows. In addition to offering an alternative to the toxic synthetic materials currently used, this approach transforms a waste product into a valuable carbon sink.
Improvement of ultra-broadband photodetection with a device based on twisted double bilayer graphene (30/09/2023)
Hyperspectral imaging uses the
full spectrum of light to give detailed insights on nature and its behavior.
These insights open a realm for manifold applications, including autonomous
driving, environmental monitoring, health care, space exploration or even
agriculture and food processing.
Orbital currents can go far—a promising novel ultrafast channel for data processing (30/09/2023)
Orbitronics is a recently
emerging field of research on the manipulation of the orbital degree of freedom
of electrons for quantum information technology. However, unambiguously
detecting ultrafast dynamics of orbital angular momentum has been challenging
so far.
Researchers dynamically tune friction in graphene (30/09/2023)
The friction on a graphene
surface can be dynamically tuned using external electric fields, according to
researchers at the University of Illinois Urbana-Champaign led by Professor
Rosa Espinosa-Marzal of the Department of Civil and Environmental Engineering.
The work is detailed in the paper, "Dynamically tuning friction at
the graphene interface using the field effect," published September 19,
2023, in the journal Nature Communications.
Researchers construct a highly efficient photocatalytic system based on titanium dioxide nanomaterials (30/09/2023)
The heterogeneous photocatalysis
(HPC) based Advanced Oxidation Process (AOP) is an eco-friendly technique for
purifying water from organic and biological pollutants in environmental
systems. The photocatalysts' overall catalytic performance usually depends on
light harvesting, photogenerated charge carrier separation and transfer, and
surface reactivity.

Case Western Reserve University
physicists are developing ultra-thin optical coatings that could dramatically
extend the life of solar panels, as well as improve areas like data storage, or
protection against counterfeiting.
3D-printed plasmonic plastic enables large-scale optical sensor production (30/09/2023)
In a multi-year project,
researchers at Chalmers University of Technology in Sweden have developed
plasmonic plastic—a type of composite material with unique optical properties
that can be 3D-printed. This research has now resulted in 3D-printed optical hydrogen
sensors that could play an important role in the transition to green energy and
industry.
