Volcanic rock–based formula reduces cement emissions by two-thirds

Leave a Comment / Electrical & Electronics, Engineering / Eduardo Paulo

Researchers have created a volcanic rock–based formula that reduces carbon emissions by 67%, potentially providing a low-cost alternative to increasingly scarce cement additives. Cement—a manufactured powder that binds concrete—is the most widely used construction material in the world, but also one of the most polluting, responsible for nearly 8% of global greenhouse gas emissions. About […]

Black Metal’ Solar Device Produces 15× More Power

Leave a Comment / Electrical & Electronics, Engineering / Eduardo Paulo

Researchers have created a solar thermoelectric generator that delivers 15 times the efficiency of the latest leading devices. Researchers aiming for greater energy independence have investigated solar thermoelectric generators (STEGs) as a way to generate electricity from the sun. Unlike conventional photovoltaic panels, STEGs can harness both direct sunlight and other forms of thermal energy.

Engineers developed a light-activated gel that boosts ion conductivity 40o TIMES

Leave a Comment / Electrical & Electronics, Engineering / Eduardo Paulo

Unlike rigid electronics, living systems are soft and flexible. MIT engineers developed a biocompatible, flexible gel whose light-controlled conductivity could advance human-machine interfaces and soft robotics. Welcome to the emerging field of ionotronics, which transmits information using ions—charged molecules—much like electronics relies on electrons. While electronic systems are established, ionotronics is still emerging—except in living

Hydrogel Coating Improves the Efficiency of Solar Panel Power Output

Electrical & Electronics, Engineering / Eduardo Paulo

A research team at The Hong Kong Polytechnic University (PolyU) has created a low-cost, easy-to-apply hydrogel coating that improves heat dissipation in solar panels by effectively cooling “hot spots,” while also boosting power generation efficiency and contributing to Hong Kong’s urban carbon-neutrality goals. Hot spots, often caused by partial shading, significantly reduce solar panel efficiency
