Using nanofaceting to manipulate quantum dots into nanocrystals (19/05/2023)
A new method of controlling the
shape of tiny particles about one tenth of the width of human hair could make
the technology that powers our daily lives more stable and more efficient,
scientists claim.
Solar Powered “Artificial Leaf” Produces Clean, Car-Ready Liquid Fuels From Sunlight (18/05/2023)
University of Cambridge
scientists have developed an ‘artificial leaf’ that, powered by sunlight,
converts CO2 and water into ethanol and propanol. This innovation eliminates
the intermediary step of producing syngas, making the technology more practical
and paving the way for a sustainable, zero-carbon emission future.
With new experimental method, researchers probe spin structure in 2D materials for first time (13/05/2023)
For two decades, physicists have
tried to directly manipulate the spin of electrons in 2D materials like
graphene. Doing so could spark key advances in the burgeoning world of 2D
electronics, a field where super-fast, small and flexible electronic devices carry
out computations based on quantum mechanics.

Unusual interactions between polymers explain hydrogel formation (03/05/2023)
Many people use hydrogels without
knowing it. As superabsorbents in nappies, for example, hydrogels absorb a lot
of liquid. In the process, the initially dry material becomes jelly-like, but
it does not wet. Some people place the swellable material on their
eyeballs—soft contact lenses are also just hydrogels. The same goes for jelly
and other everyday materials.
Silver nanoparticles spark key advance in thermoelectricity for power generation (03/05/2023)
Several high-performance
thermoelectric materials have been discovered over the past two decades, but
without efficient devices to convert the energy they produce into emission-free
power, their promise has been unfulfilled. Now an international team of scientists
led by a University of Houston physicist and several of his former students has
reported a new approach to constructing the thermoelectric modules, using
silver nanoparticles to connect the modules' electrode and metallization
layers.
Engineering graphene-based quantum circuits with atomic precision (03/05/2023)
Imagine having a building made of
stacks of bricks connected by adaptable bridges. You pull a knob that modifies
the bridges and the building changes functionality. Wouldn't it be great?
Researchers fabricate mechanical metamaterials with ultra-high energy absorption capacity (03/05/2023)
Chinese researchers have
successfully fabricated mechanical metamaterials with ultra-high energy
absorption capacity using ion track technology. The results were published
in Nature Communications as an Editor's Highlight.
Nanowire networks learn and remember like a human brain (03/05/2023)
An international team led by
scientists at the University of Sydney has demonstrated nanowire networks can
exhibit both short- and long-term memory like the human brain.
New programmable smart fabric responds to temperature and electricity (03/05/2023)
A new smart material developed by
researchers at the University of Waterloo is activated by both heat and
electricity, making it the first ever to respond to two different stimuli.
