An international team of researchers has discovered a new method to generate electricity using small plastic beads. By placing these beads close together and bringing them into contact, they generate more electricity than usual. This process, known as triboelectrification, is similar to the static electricity produced when rubbing a balloon against hair. /news/2025-03-scientists-smart-generate-energy-tiny.html Nanophysics Nanomaterials Tue, 11 Mar 2025 12:25:03 EDT news660914701 In a study published in Device has reported a new self-powered electrostatic tweezer that offers superior accumulation and tunability of triboelectric charges, enabling unprecedented flexibility and adaptability for manipulating objects in various working scenarios. The research team was led by Dr. Du Xuemin from the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese Academy of Sciences /news/2024-07-powered-electrostatic-tweezer-microfluidics.html Soft Matter Fri, 26 Jul 2024 13:43:31 EDT news641220201 The fracturing and friction of coffee beans during grinding generates electricity that causes coffee particles to clump together and stick to the grinder. Researchers report Dec. 6 in the journal Matter that coffee beans with higher internal moisture produce less static electricity, which means less coffee is wasted and there is less mess to clean up. /news/2023-12-coffee-splash-static-electricity-intense.html General Â鶹ÒùÔºics Wed, 06 Dec 2023 11:00:02 EST news621081033 Corrosion causes significant losses to various industries. Cathodic protection is used to protect steel in marine industries. Triboelectric nanogenerators (TENG) converts mechanical energy into electricity based on triboelectrification and electrostatic induction. TENG cathodic protection is in line with the requirements of contemporary low-carbon energy conservation. /news/2023-09-team-sponge-based-triboelectric-nanogenerator-corrosion.html Nanomaterials Tue, 05 Sep 2023 10:34:52 EDT news613128889 Contact electrification can arise when physical contact occurs between two materials. In a new report now published on Science Advances, Ding Li, and a team of scientists in nanoscience, nanoenergy and materials science in China and the U.S., detailed atomic-featured photon emission spectra between two solid materials. Electron transfer can take place at the interface from an atom in one material to another atom in another material, alongside photon emission, during contact electrification. /news/2021-10-inter-atomic-photon-emission-contact-electrification.html Nanophysics Thu, 14 Oct 2021 09:10:01 EDT news553415900 Super-micro, low-power sensors and devices that can send and receive signals and information anytime, anywhere will become an integral part of people's lives in a hyper-connected world driven by the Internet of Things (IoT). An important issue is continually supplying electricity to the countless electronic devices connected to the system. This is because it is difficult to reduce the size and weight of the battery using the conventional way of charging and changing it. /news/2020-10-haptic-sensor-static-electricity.html Nanomaterials Mon, 05 Oct 2020 07:31:21 EDT news521101878 Scientists have dedicated intense work in recent years to convert environmental energy into electricity to meet the ongoing demands for a cleaner and more sustainable power source. Harvesting environmental mechanical energy as an eco-friendly method is a promising solution and plays a significant role in building wearable electronics and sensor networks in the Internet of Things (IoTs). A triboelectric nanogenerator (TENG) is a self-powered, feasible solution to convert mechanical energy into electricity and specifically satisfy the increasing demand of the internet of things (IoTs). /news/2019-04-next-generation-triboelectric-nanogenerator-teng-constant.html Nanophysics Mon, 15 Apr 2019 09:30:02 EDT news474533072 Six authors have described their work in harvesting energy in a paper titled "Ultrathin, Rollable, Paper-Based Triboelectric Nanogenerator for Acoustic Energy Harvesting and Self-Powered Sound Recording." Translation: A paper microphone may help charge your cellphone. Jacob Aron in New Scientist wrote about their work; he said one benefit of such a microphone is that it could harvest acoustic energy to top up a phone charge on the go. The team, from the Georgia Institute of Technology in the U.S. and Chongqing University and Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, China, published their paper in ACS Nano last month. /news/2015-04-states-china-team-explore-energy.html Nanophysics Sat, 18 Apr 2015 04:50:01 EDT news348542228 By the end of 2014, Earth will be home to more mobile electronic devices than people.

Rather than plugging it into the wall, you become the power source. Researchers at the 247th National Meeting & Exposition of the American Chemical Society (ACS) presented these commercial possibilities and a unique vision for green energy. /news/2014-03-harnessing-everyday-motion-power-mobile.html Energy & Green Tech Sun, 16 Mar 2014 06:13:54 EDT news314169215 (Â鶹ÒùÔº) —With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs – with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps from a fingertip to a doorknob when you walk across carpet on a cold, dry day. Wang and his research team have learned to harvest this power and put it to work. /news/2013-12-capturing-electricity-triboelectric.html Nanophysics Tue, 10 Dec 2013 09:20:01 EST news305888300
