Researchers tested a molecular energy harvesting device that captures the energy from the natural motion of molecules in a liquid. Their work showed molecular motion can be used to generate a stable electric current. To create the device, they submerged nanoarrays of piezoelectric material in liquid, allowing the movement of the liquid to move the strands like seaweed waving in the ocean, except in this case the movement is on the molecular scale, and the strands are made of zinc oxide. When the zinc oxide material waves, bends, or deforms under motion, it generates electric potential.

New pharmaceuticals, cleaner fuels, biodegradable plastics: in order to meet society's needs, chemists have to develop new synthesis methods to obtain new products that do not exist in their natural state. A research group has discovered how to use an external electric field to control and accelerate a chemical reaction, like a 'switch'. This work could have a considerable impact on the development of new molecules, enabling not only more environmentally friendly synthesis, but also very simple external control of a chemical reaction.

Lithium–sulfur batteries (LSBs) offer a higher energy storage potential. However, issues like formation of lithium polysulfides and lithium dendrites lead to capacity loss and raise safety concerns. Now, researchers have developed a graphene separator embedded with platinum-doped gold nanoclusters, which enhance lithium-ion transport and facilitate redox reactions. This breakthrough addresses the long-standing issues associated with LSBs, setting the stage for their commercialization.

Engineers developed electronic 'stickers' that measure the force exerted by one object upon another. The force stickers are wireless, run without batteries and fit in tight spaces, making them versatile for a wide range of applications, from surgical robots to smart implants and inventory tracking.

Scientists have developed a new modular steel buttress dam system designed to resolve energy storage issues hindering the integration of renewable resources into the energy mix. The new modular steel buttress dam system facilitates the rapid construction of paired reservoir systems for grid-scale energy storage and generation using closed-loop pumped storage hydropower, cutting dam construction costs by one-third and reducing construction schedules by half.

Researchers have developed a data-driven AI algorithm for controlling the heating and cooling of an office building. The system does not require ambient sensors or specific knowledge of the building's rooms. During heating operations, the system was able to achieve energy savings of up to 30%, which can represent significant reductions to cost and environmental impact.

Can artificial intelligence (AI) get hungry? Develop a taste for certain foods? Not yet, but a team of researchers is developing a novel electronic tongue that mimics how taste influences what we eat based on both needs and wants, providing a possible blueprint for AI that processes information more like a human being.

Insect cyborgs may sound like something straight out of the movies, but hybrid insect computer robots, as they are scientifically called, could pioneer a new future for robotics. It involves using electrical stimuli to control an insect’s movement. Now, an international research group has conducted a study on the relationship between electrical stimulation in stick insects' leg muscles and the resulting torque (the twisting force that causes the leg to move).

As the internet quickly fills with viral videos of futuristic robots darting and racing around like the animals they’re built to mimic, researchers say that there’s an element of their movement’s programming that should not be overlooked: rhythm.

Researchers developed the first AI to date that can intelligently design robots from scratch by compressing billions of years of evolution into mere seconds. It's not only fast but also runs on a lightweight computer and designs wholly novel structures from scratch — without human-labeled, bias-filled datasets.

Engineers and scientists look at how thoughtful design can reduce a sustainably-designed neighborhood’s energy vulnerability during power disruptions, as well as which design characteristics are needed if and when local populations need to move to shelters. Researchers  analyzed the design and energy characteristics of particular kinds of buildings and neighborhoods to assess their vulnerabilities and their access to alternative and renewable energy sources. The authors use several scenarios involving different lengths of power disruption to see which kind of response is most beneficial to the populations affected.

Scientists have characterized the genome of a metal-loving bacteria with an affinity for rare earth elements. The research paves the way towards replacing the harsh chemical processing of these elements with a benign practice called biosorption.
