Impressive new plastic self-heals, can be recycled and feeds marine life (05/11/2023)
Solving a long-standing problem in transmission electron microscopy (04/11/2023)
For researchers wanting to
understand the inner workings of magnetic materials, transmission electron
microscopy is an indispensable tool. Because the wavelength of an electron is
much shorter than the wavelength of visible light, a beam of electrons transmitted
through a thin slice of a material can create an image in which the inner
structure of the material is magnified up to 50 million times, many orders of
magnitude more than with an optical microscope.
Scientists use supercomputers to make optical tweezers safer for living cells (03/11/2023)
Optical tweezers manipulate tiny
things like cells and nanoparticles using lasers. While they might sound like
tractor beams from science fiction, the fact is their development garnered scientists
a Nobel Prize in 2018.
First-ever wireless device developed to make magnetism appear in non-magnetic materials (02/11/2023)
Researchers at the UAB and ICMAB
have succeeded in bringing wireless technology to the fundamental level of
magnetic devices. The emergence and control of magnetic properties in cobalt
nitride layers (initially non-magnetic) by voltage, without connecting the
sample to electrical wiring, represents a paradigm shift that can facilitate
the creation of magnetic nanorobots for biomedicine and computing systems where
basic information management processes do not require wiring.
Strange magnetic material could make computing energy-efficient (02/11/2023)
A research collaboration co-led
by EPFL has uncovered a surprising magnetic property of an exotic material that
might lead to computers that need less than one-millionth of the energy
required to switch a single bit.
Multimodal graphene-based e-textiles for the realization of customized e-textiles developed for the first time. (31/10/2023)
A joint research team led by
Principal Researcher Soongeun Kwon and Professor Young-Jin Kim has developed
graphene-based, customized e-textiles, for the first time in the world.
They published their findings in ACS Nano in a paper
titled, "Multimodal E-Textile Enabled by One-Step Maskless Patterning of
Femtosecond-Laser-Induced Graphene on Nonwoven, Knit, and Woven Textiles."
Hybrid nanomaterials promise a sustainability boost across multiple industries (31/10/2023)
Polyoxometalate (POM)-based
nanohybrids potentially offer a step-change in sustainability across a wide
variety of industries, but research into the substances is in its infancy. A
group of researchers has produced a comprehensive review of the sector's progress
and challenges yet to be overcome.
Electrodes with hollow nanotubes improve performance of potassium-ion batteries (31/10/2023)
Researchers
who are working to find alternatives to lithium-ion batteries have turned their
attention to potassium-ion batteries. Potassium is an abundant resource, and
the technology functions in much the same way as lithium-ion batteries, but
these batteries have not been developed at a large scale because the ionic
radius causes problems in energy storage and substandard electrochemical
performance.
Scientists develop new method to create stable, efficient next-gen solar cells (31/10/2023)
Next-generation solar materials
are cheaper and more sustainable to produce than traditional silicon solar
cells, but hurdles remain in making the devices durable enough to withstand
real-world conditions. A new technique developed by a team of international
scientists could simplify the development of efficient and stable perovskite
solar cells, named for their unique crystalline structure that excels at
absorbing visible light.
Researchers devise cleaner, more efficient production of key input for detergents (31/10/2023)
Conventional techniques of
generating alkylbenzene, a key input in the production of detergents, produce
toxic halogen byproducts, but researchers have devised a new technique that
offers a more efficient, cheaper and cleaner manufacturing process of the
substance.
