Published New sodium, aluminum battery aims to integrate renewables for grid resiliency
(via sciencedaily.com) A new sodium battery technology shows promise for helping integrate renewable energy into the electric grid. The battery uses Earth-abundant raw materials such as aluminum and sodium.
Published A quasiparticle that can transfer heat under electrical control
(via sciencedaily.com) Scientists have found the secret behind a property of solid materials known as ferroelectrics, showing that quasiparticles moving in wave-like patterns among vibrating atoms carry enough heat to turn the material into a thermal switch when an electrical field is applied externally.
Published Passive radiative cooling can now be controlled electrically
(via sciencedaily.com) Energy-efficient ways of cooling buildings and vehicles will be required in a changing climate. Researchers have now shown that electrical tuning of passive radiative cooling can be used to control temperatures of a material at ambient temperatures and air pressure.
Published Powering wearable technology with MXene textile supercapacitor 'patch'
(via sciencedaily.com) Researchers are one step closer to making wearable textile technology a reality. Materials scientists have reported a new design of a flexible wearable supercapacitor patch. It uses MXene to create a textile-based supercapacitor that can charge in minutes and power an Arduino microcontroller temperature sensor and radio communication of data for almost two hours.
Published Researchers demo new type of carbon nanotube yarn that harvests mechanical energy
(via sciencedaily.com) Nanotechnology researchers have made novel carbon nanotube yarns that convert mechanical movement into electricity more effectively than other material-based energy harvesters.
Published Transistors repurposed as microchip 'clock' address supply chain weakness
(via sciencedaily.com) A new technique uses standard chip fab methods to fabricate the building block of a timing device, critical to all microprocessors. Currently, this timing device, known as an acoustic resonator, must be produced separately, often overseas, creating a supply chain and security weakness. The technique would allow for this timing device to be integrated with the microprocessor using standard CMOS processing, rather than later bunded with the microprocessor.
Published Artificial photosynthesis uses sunlight to make biodegradable plastic
(via sciencedaily.com) Scientists have succeeded in synthesizing fumaric acid, a raw material for plastics, from CO2 powered by solar energy. Typically, fumaric acid is synthesized from petroleum as a raw material to make polybutylene succinate, a biodegradable plastic, but this research shows that it can be synthesized from CO2 and biomass-derived compounds using renewable energy.
Published Plasma thrusters used on satellites could be much more powerful
(via sciencedaily.com) Original source It was believed that Hall thrusters, an efficient kind of electric propulsion widely used in orbit, need to be large to produce a lot of thrust. Now, a new study suggests that smaller Hall thrusters can generate much more thrust -- potentially making them candidates for interplanetary missions.
Published Recyclable mobile phone batteries a step closer with rust-busting invention
(via sciencedaily.com) Mobile phone batteries with a lifetime up to three times longer than today's technology could be a reality thanks to a recent innovation.
Published Spin transport measured through molecular films now long enough to develop spintronic devices
(via sciencedaily.com) Original source A research group has succeeded in measuring spin transport in a thin film of specific molecules -- a material well-known in organic light emitting diodes -- at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been used to control spin transport in the past, the thin molecular film used in this study is photoconductive, allowing spin transport control using visible light.
Published Polysulfates could find wide use in high-performance electronics components
(via sciencedaily.com) Flexible compounds made with Nobel-winning click chemistry can be used in energy-storing capacitors at high temperatures and electric fields.
