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
(via sciencedaily.com) 
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 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.
Published More predictable renewable energy could lower costs
(via sciencedaily.com) 
Lower electricity costs for consumers and more reliable clean energy could be some of the benefits of a new study by researchers who have examined how predictable solar or wind energy generation is and the impact of it on profits in the electricity market.

A research team develops semiconductor devices for high-performance AI operations by applying IGZO materials widely used in OLED displays.
Published Visualizing spatial distribution of electric properties at microscales with liquid crystal droplets
(via sciencedaily.com) 
Existing sensor probes for microelectrical devices can measure only their average electric properties, providing no information on their spatial distribution. Liquid crystal droplets (LCDs) -- microscopic droplets of soft matter that respond to electric field -- are promising in this regard. Accordingly, researchers recently visualized the electric field and electrostatic energy distribution of microstructured electrodes by recording the motion of LCDs under an applied voltage, making for high detection accuracy and spatial resolution.
Published Optical switching at record speeds opens door for ultrafast, light-based electronics and computers
(via sciencedaily.com) 
Imagine a home computer operating 1 million times faster than the most expensive hardware on the market. Now, imagine that being the industry standard. Physicists hope to pave the way for that reality.

Scientists have created a comprehensive 'roadmap' to guide global efforts to convert waste energy into clean power.
Published Robot caterpillar demonstrates new approach to locomotion for soft robotics
(via sciencedaily.com) 
Researchers have demonstrated a caterpillar-like soft robot that can move forward, backward and dip under narrow spaces. The caterpillar-bot's movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, allowing users to steer the robot in either direction.
Published New invention: The oxygen-ion battery
(via sciencedaily.com) 
An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.
