Researchers demonstrate a technique to harness electrochemical energy released when the oxide layer on liquid metals reforms after being ruptured. This approach enables new kinds of soft, stretchable batteries and self-powered devices.
Novel double membrane biobattery design inspired by mitochondria achieves high energy density and biocompatibility, enabling advanced implantable devices.
Researchers have created a new type of electricity generator that uses falling water droplets more efficiently, thanks to groundbreaking 4D printing techniques.
By adopting a single-enzyme approach, scientists have unlocked a new era in enzymatic biofuel cell technology, where one device serves a dual purpose: harvesting electricity and providing an analytical signal for glucose detection, all powered by a single enzyme, glucose oxidase, on both the anode and cathode.
Researchers report single molecule studies of energy transfer using a quantum dot donor with an organic dye acceptor. They demonstrate that suppression of the blinking of the QD donor minimizes the loss of energy, which is achieved by a simple surface treatment method.
Triboelectric nanogenerators (TENGs) are rapidly emerging as a cutting-edge technology with the potential to revolutionize the marine industry. As a novel technology that has made significant progress over the past decade, TENGs have been regarded as one of the most efficient methods for harvesting low-frequency ocean energy.
The extensive use of polymer-made, disposable and non-biodegradable COVID-19 pandemic health protectives like surgical face masks, hand gloves and PPE kits, combined with a lack of proper waste recycling systems, considerably increased plastic pollution around the world. Researchers are harnessing a new way to turn these COVID-19 pandemic wastes towards sensor design by fabricating a mask-glove-based contact-separation triboelectric nanogenerator (MG-CS TENG).
By mimicking a biological cell plasma membrane, i.e. the membrane that separates the interior of the cell from the outside environment, researchers have demonstrated that a 2D reduced graphene oxide membrane can regulate complex polysulfide chemistry in lithium-sulfur batteries. The efficiency of this separator in controlling the polysulfide chemistry and its sub-micron thickness allows to minimize the amount of electrolyte needed, which enables lightweight, high energy density batteries.
