Published New gels could protect buildings during wildfires
(via sciencedaily.com) Original source Researchers have developed a sprayable gel that creates a shield to protect buildings from wildfire damage. It lasts longer and is more effective than existing commercial options.
Published Engineers design lookalike drug carrier to evade lung's lines of defense
(via sciencedaily.com) Original source Managing hard-to-treat respiratory illnesses like asthma and pulmonary fibrosis just got easier if a new drug-carrying molecule is as sneaky as its inventors think.
Published New nano-device could mean your run could power your electrical wearables
(via sciencedaily.com) Original source Your early morning run could soon help harvest enough electricity to power your wearable devices, thanks to new nanotechnology.
Published DNA tech offers both data storage and computing functions
(via sciencedaily.com) Original source Researchers have demonstrated a technology capable of a suite of data storage and computing functions -- repeatedly storing, retrieving, computing, erasing or rewriting data -- that uses DNA rather than conventional electronics. Previous DNA data storage and computing technologies could complete some but not all of these tasks.
Published Molecular wires with a twist
(via sciencedaily.com) Original source Researchers have developed molecular wires with periodic twists. By controlling the lengths of regions between twists, the electrical conductivity of individual polymer chains can be enhanced. This work may lead to novel organic electronics or single-molecule wires.
Published Action plan to help patients with lung disease cope with wildfire smoke
(via sciencedaily.com) Original source A multidisciplinary team has developed an action plan to help patients with respiratory diseases mitigate the consequences of poor air quality from wildfires.
Published Less severe forest fires can reduce intensity of future blazes
(via sciencedaily.com) Original source Low- and moderate-severity forest wildfires can reduce the intensity of future fires, according to new research on 'reburns.'
Published Morphable materials: Researchers coax nanoparticles to reconfigure themselves
(via sciencedaily.com) Original source A view into how nanoscale building blocks can rearrange into different organized structures on command is now possible with an approach that combines an electron microscope, a small sample holder with microscopic channels, and computer simulations, according to a new study.
Published Revolutionizing thermoelectric technology: Hourglass-shaped materials achieve a 360% efficiency boost
(via sciencedaily.com) Original source A groundbreaking technology has been unveiled that improves the efficiency of thermoelectric materials, which are key in converting waste heat into electricity, by altering their geometry to resemble an hourglass. Unlike previous research that solely depended on the material properties of thermoelectric substances, this new approach is expected to have widespread applications in thermoelectric power generation.
Published Research provides a roadmap for improving electrochemical performance
(via sciencedaily.com) Original source A study expands understanding on how electrons move through the conductive parts of complex fluids found in electrochemical devices such as batteries. This work can help overcome existing knowledge gaps for engineers seeking to improve the performance of these devices.
Published Quantum pumping in molecular junctions
(via sciencedaily.com) Original source Researchers have developed a new theoretical modelling technique that could potentially be used in the development of switches or amplifiers in molecular electronics.
Published Physicists throw world's smallest disco party
(via sciencedaily.com) Original source A new milestone has been set for levitated optomechanics as a group of scientists observed the Berry phase of electron spins in nano-sized diamonds levitated in vacuum.
Published Scientists create material that can take the temperature of nanoscale objects
(via sciencedaily.com) Original source Scientists recently discovered a one-dimensional nanoscale material whose color changes as temperature changes.
Published Exploring the structures of xenon-containing crystallites
(via sciencedaily.com) Original source Noble gases have a reputation for being unreactive, inert elements, but more than 60 years ago Neil Bartlett demonstrated the first way to bond xenon. He created XePtF6, an orange-yellow solid. Because it's difficult to grow sufficiently large crystals that contain noble gases, some of their structures -- and therefore functions -- remain elusive. Now, researchers have successfully examined tiny crystallites of noble gas compounds. They report structures of multiple xenon compounds.
Published Climate change raised the odds of unprecedented wildfires in 2023-24
(via sciencedaily.com) Original source Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.
Published Scientists achieve more than 98% efficiency removing nanoplastics from water
(via sciencedaily.com) Original source Linked to cardiovascular and respiratory diseases in people, nanoplastics continue to build up, largely unnoticed, in the world's bodies of water. The challenge remains to develop a cost-effective solution to get rid of nanoplastics while leaving clean water behind. That's where Mizzou comes in. Recently, researchers created a new liquid-based solution that eliminates more than 98% of these microscopic plastic particles from water.
Published Breakthrough in nanotechnology: Viewing the invisible with advanced microscopy
(via sciencedaily.com) Original source Scientists have made a groundbreaking discovery in the field of nanotechnology. They have developed a novel microscopy method that allows for the unprecedented visualization of nanostructures and their optical properties.
Published Why carbon nanotubes fluoresce when they bind to certain molecules
(via sciencedaily.com) Original source Nanotubes can serve as biosensors. They change their fluorescence when they bind to certain molecules. Until now, it was unclear why. Researchers have gained new insights into the cause of the fluorescence.
Published Innovative study unveils a new path in green chemistry
