Published Cities will need more resilient electricity networks to cope with extreme weather
(via sciencedaily.com)
Original source 
Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps, according to a new study.
Published Shutting down nuclear power could increase air pollution
(via sciencedaily.com)
Original source 
A new study shows that if U.S. nuclear power plants are retired, the burning of coal, oil, and natural gas to fill the energy gap could cause more than 5,000 premature deaths.

(via sciencedaily.com)
Original source 
To manage atmospheric carbon dioxide and convert the gas into a useful product, scientists have dusted off an archaic -- now 120 years old -- electrochemical equation.
Published Shedding light on mechanisms of electrochemical energy storage
(via sciencedaily.com)
Original source 
Researchers have developed a new technique that can quickly identify the exact electrochemical mechanisms taking place in batteries and supercapacitors of various compositions -- a breakthrough that could speed the design of higher performing energy storage devices.
Published Discovery of ferroelectricity in an elementary substance
(via sciencedaily.com)
Original source 
Researchers have discovered a new single-element ferroelectric material that alters the current understanding of conventional ferroelectric materials and has future applications in data storage devices.
Published Levies on Renewable Energy Profits could serve as a barrier to achieving Net Zero Targets in the UK
(via sciencedaily.com)
Original source 
Placing levies on the profits made in the renewable energy industry could hinder the UK's ability to meet its 2050 net zero carbon reduction targets, an expert has said.
Published Major storage capacity in water-based batteries
(via sciencedaily.com)
Original source 
Chemical engineers have discovered a 1,000% difference in the storage capacity of metal-free, water-based battery electrodes.
Published Smart films help to make loudspeakers lighter and more energy-efficient
(via sciencedaily.com)
Original source 
Scientists are developing intelligent materials that are opening up new avenues in sound reproduction technology: lightweight loudspeakers that use far less energy than their conventional counterparts, novel shapes for sound and signal generators and applications involving noise cancelling textiles. The basis for these smart materials are ultrathin silicone films that can act as artificial muscles with their own built-in sensors.
Published Mathematical model provides bolt of understanding for lightning-produced X-rays
(via sciencedaily.com) 
In the early 2000s, scientists observed lightning discharge producing X-rays comprising high energy photons -- the same type used for medical imaging. Researchers could recreate this phenomenon in the lab, but they could not fully explain how and why lightning produced X-rays. Now, two decades later, a team has discovered a new physical mechanism explaining naturally occurring X-rays associated with lightning activity in the Earth's atmosphere.
Published Energy-efficient and customizable inorganic membranes for a cleaner future
(via sciencedaily.com) 
A team of researchers has developed a revolutionary technique for producing ultrathin inorganic membranes. These inorganic membranes are not just energy-efficient but also highly customizable for different applications, such as filtration, separation, energy conversion, catalysis and sensing. This ground-breaking achievement could potentially revolutionize the way many industries operate for greater sustainability.
Published Revolutionary battery technology to boost EV range 10-fold or more

A team develops layering-charged, polymer-based stable high-capacity anode material.
Published Eco-efficient cement could pave the way to a greener future
(via sciencedaily.com) 
Scientists develop process to remove toxic heavy metals from coal fly ash, making for greener, stronger concrete.
Published Highly charged ions melt nano gold nuggets
(via sciencedaily.com)
Original source 
Shooting ions is very different from shooting a gun: By firing highly charged ions onto tiny gold structures, these structures can be modified in technologically interesting ways. Surprisingly, the key is not the force of impact, but the electric charge of the projectiles.
Published The powerhouse of the future: Artificial cells
(via sciencedaily.com) 
Researchers identify the most promising advancements and greatest challenges of artificial mitochondria and chloroplasts. The team describes the components required to construct synthetic mitochondria and chloroplasts and identifies proteins as the most important aspects for molecular rotary machinery, proton transport, and ATP production. The authors believe it is important to create artificial cells with biologically realistic energy-generation methods that mimic natural processes; replicating the entire cell could lead to future biomaterials.
Published First silicon integrated ECRAM for a practical AI accelerator
(via sciencedaily.com) 
The transformative changes brought by deep learning and artificial intelligence are accompanied by immense costs. For example, OpenAI's ChatGPT algorithm costs at least $100,000 every day to operate. This could be reduced with accelerators, or computer hardware designed to efficiently perform the specific operations of deep learning. However, such a device is only viable if it can be integrated with mainstream silicon-based computing hardware on the material level.
Published Some coastal salt marshes are keeping up with sea level rise -- for now
(via sciencedaily.com) 
The world's salty, tidal marshes are hotspots of carbon storage and productivity, building up sediments and plant material to stay above sea level. However, as sea level rises at an increasing rate, scientists debate whether it's possible for wetlands to win the race. New research reveals how salt marshes along the U.S. East Coast have responded to accelerating sea level rise by building elevation more quickly to keep pace with the sea over the last century.
Published Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells
(via sciencedaily.com) 
Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.
