[center]Researchers design scalable graphene sensor array for
real-time [glow=red,2,300][color=maroon]toxins[/glow] monitoring
in flowing 💧 water[/color][/center]
A team of researchers, led by the University of
Wisconsin-Milwaukee, recently developed a path to
mass-manufacture high-performance graphene sensors that can
detect heavy metals and bacteria in flowing tap water. This
advance could bring down the cost of such sensors to just US $1
each

/>allowing people to test their drinking water for toxins at
home.
The sensors have to be extraordinarily sensitive to catch the
minute concentrations of toxins that can cause harm. For
example, the U.S. Food and Drug Administration states that
bottled water must have a lead concentration of no more than 5
parts per billion. Today, detecting parts-per-billion or even
parts-per-trillion concentrations of heavy metals, bacteria, and
other toxins is only possible by analyzing water samples in the
laboratory, says Junhong Chen, a professor of molecular
engineering at the University of Chicago and the lead water
strategist at Argonne National Laboratory. But his group has
developed a sensor with a graphene field-effect transistor (FET)
that can detect toxins at those low levels within seconds.

[center]GMG reports that its plant is now
[glow=blue,2,300]operational[/glow][/center]
Graphene Manufacturing Group (GMG) has announced that it has
commissioned its graphene-enhanced coating blending plant and it
is now operational after making its first 1,000-liter blend.
Updating investors on the commercialization progress and sales
development of THERMAL-XR, the Company said the blending plant
is expected to have the capacity to produce up to 500,000 liters
of THERMAL-XR ⚡ RESTORE coating a year, subject to
graphene production, when operating two blends per eight-hour
shift, 250 days per year. This capacity enables future service
growth well into the future, it added.

[center]Stanford and UC Berkeley teams produce graphene aerogel
in space[/center]
A team of researchers from Stanford University and the
University of California, Berkeley are reportedly leveraging the
International Space Station (ISS) National Laboratory to produce
higher-quality graphene aerogel than is possible on Earth.
It was announced that this week, the Crew-6 astronauts onboard
the space station completed work on the team’s investigation,
which was funded by the U.S. National Science Foundation (NSF).
The results could provide new insights into the underlying
physics of graphene aerogel synthesis and lead to the
development of novel material products.

[center]Researchers examine the reason for graphene's
permeability to protons[/center]
Researchers from The University of Warwick, the University of
Manchester, Brazil's Universidade Federal do Ceara and Turkey's
Izmir Institute of Technology have tackled the long-standing
conundrum of why graphene is so much more permeable to protons
than expected by theory.
A decade ago, scientists at The University of Manchester
demonstrated that graphene is permeable to protons, nuclei of
hydrogen atoms. The unexpected result sparked a debate because
theory predicted that it would be extremely hard for a proton to
permeate through graphene's dense crystalline structure. This
had led to suggestions that protons permeate not through the
crystal lattice itself, but through the pinholes in its
structure.

[center]Researchers design novel nonlinear 💫 circuit to
harvest ⚡ power using
[glow=green,2,300]graphene[/glow][/center]
Obtaining useful work from random fluctuations in a system at
thermal equilibrium has long been considered impossible. In
fact, in the 1960s eminent American physicist Richard Feynman
effectively shut down further inquiry after he argued in a
series of lectures that Brownian motion, or the thermal motion
of atoms, cannot perform useful work. Recently, however, a new
study has shown that Feynman may have been inaccurate.
Three of the paper’s five authors are from the University of
Arkansas Department of Physics. According to first author Paul
Thibado, their study rigorously proves that thermal fluctuations
of freestanding graphene, when connected to a circuit with
diodes having nonlinear resistance and storage capacitors, does
produce useful work by charging the storage capacitors.

graphene heat management technology[/center]
At the beginning of June 2023, Asus unveiled the Asus ROG Swift
OLED PG49WCD, a gaming monitor that uses graphene for thermal
management. Now, Asus has added the PG32UCDM and PG34WCDM gaming
monitors, each based on a different OLED panel technology.

WOLED curved panel, produced by LG Display. Both monitors make
use of a graphene film for heat dissipation.

[center]AMD announces additional contract with NASA’s Jet
Propulsion Laboratory[/center]
Advanced Material Development (AMD) has announced signing a
further contract with NASA’s Jet Propulsion Laboratory (JPL).
AMD’s Radar absorbing technology is now being incorporated by
AMD into foam panels and will be used by JPL during the system
level electromagnetic compatibility test for the Europa Clipper
spacecraft later this year.
The Europa Clipper spacecraft will perform dozens of close
flybys of Jupiter’s moon Europa, gathering detailed measurements
from multiple instruments, including the radar instrument, to
investigate whether the moon could have conditions suitable for
life. Europa Clipper’s primary objective is to determine whether
there are places below Europa’s surface that could support life.

[center]Researchers develop rGO-enhanced structural
supercapacitors[/center]
Researchers from the University of California San Diego and the
University of Southern Mississippi recently designed a
graphene-enhanced structural supercapacitor. Structural
supercapacitors hold promise to expand the energy capacity of a
system by integrating load-bearing and energy-storage functions
in a multifunctional structure, resulting in weight savings and
safety improvements.

As a proof of concept, the researchers used their structural
supercapacitor to build a miniature solar-powered boat. The
supercapacitor was molded to form the boat’s hull and then
fitted with a small motor and circuit. The circuit was connected
to a solar cell. When exposed to sunlight, the solar cell
charges the supercapacitor, which in turn powers the boat’s
motor. In tests, the boat was able to cruise across the water,
demonstrating the efficacy of this innovative energy storage
solution.
