I am thrilled to share that our new review-paper on Magnesium-based thermoelectric materials has been published in #ACSAppliedEnergyMaterials.. As known, thermoelectric materials produce clean electrical energy from the waste heat released from various industries like automobile. However, the use of some of TE materials is limited as they have insufficient thermoelectric performance, low mechanical properties and unreliable microstructural stability at high temperatures.. This paper reviewed the current limitations of Mg-based materials, summarised the progresses and provide crucial insights for the future applications..

When consumers could store heat they do not use and sell it in a market, total energy loss could be halved. 🌡 That is the ultimate goal of Kamel Hooman, professor of Heat Transformation Technology. In order to achieve this, it is crucial that heat can be efficiently stored and transported. 🚚 Hooman will explain how he intends to achieve this in his inaugural speech later today.

𝗕𝗿𝗼𝗻𝘇𝗲 𝗔𝗴𝗲 𝘁𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝘆 𝗰𝗼𝘂𝗹𝗱 𝗮𝗶𝗱 𝘀𝘄𝗶𝘁𝗰𝗵 𝘁𝗼 𝗰𝗹𝗲𝗮𝗻 𝗲𝗻𝗲𝗿𝗴𝘆 by Corey Binns; Stanford University via Tech Xplore Technology with roots going back to the #BronzeAge may offer a fast and inexpensive #solution to help achieve the #UnitedNations climate goal of #netzero emissions by 2050, according to recent Stanford-led research in PNAS Nexus. The #technology involves assembling heat-absorbing #bricks in an insulated #container, where they can store heat generated by #solar or #wind #power for later use at the #temperatures required for #industrial #processes. The #heat can then be released when needed by passing air through channels in the stacks of "#firebricks," thus allowing #cement, #steel, #glass, and #paper factories to run on #renewableenergy even when wind and sunshine are unavailable. These #systems, which several companies have recently begun to commercialize for industrial #heatstorage, are a form of #thermalenergy storage. The bricks are made from the same materials as the insulating bricks that lined primitive #kilns and #ironmaking #furnaces thousands of years ago. To optimize for heat storage instead of #insulation, the materials are combined in different amounts. Batteries can store #electricity from #renewable #sources and provide electricity to generate heat on #demand. "The difference between firebrick storage and battery storage is that the firebricks store heat rather than electricity and are one-tenth the cost of #batteries," said lead study author Mark Jacobson, a professor of civil and environmental engineering in the Stanford Doerr School of Sustainability and Stanford University School of Engineering. "The materials are much simpler too. They are basically just the components of dirt." The full article link is here: https://lnkd.in/d9kwWBGT

This account is dedicated to the discovery and sharing of excellent work and scientific progress in the field of nanogenerators.
【Interface Charge Regulation Enhancing Output and Durability of Triboelectric Nanogenerator for Efficient Wastewater Treatment】 Advanced Energy Materials (IF 24.4) Pub Date : 2024-07-06 , DOI:10.1002/aenm.202401958 Harvesting mechanical energy through triboelectric nanogenerators (TENGs) for effectively purifying water, self-powered wastewater treatment system presents a promising solution to address both energy and environmental crises. However, issues such as side-discharge and wear, resulting from interfacial charge transfer, seriously hinder the output and durability of TENGs, and then reduce the efficiency of self-powered wastewater treatment. Here, an interface charge regulation technique is introduced that simultaneously boosts both output performance and durability of TENG, enabling a greater efficiency in self-powered wastewater treatment. The interface charge regulation method, suppressing side-discharge around electrodes with an innovative insulator design as well as boosting charge density through secondary collection, fully utilizes surface charges for power output and results in minimum wear by reducing the interface electrostatic force. Surface charge density of 0.8 mC m−2 between the Ethyl tetrafluoro ethylene and copper (µ = 0.35), with a threefold enhancement under ambient conditions, and durability of 500 000 cycles (a 12.5-fold enhancement) are achieved. Furthermore, the removal efficiency for proposed self-powered sewage filter system is improved onefold, indicating the potential for sustainable and practical applications. https://lnkd.in/eFsc6PAK

Artificial ‘power plant’ generates electricity using wind and rain 🌱 🌱 🌱 🍀 An international team of scientists led by Prof. Ravinder Dahiya from Boston’s Northeastern University has developed literal “power plants” – tiny, leaf-shaped generators that create electricity from a blowing breeze or falling raindrops. The team tested the energy harvesters by incorporating them into artificial plants. 🍀 The team developed two different types of energy collectors – the triboelectric nanogenerator (TENG) to harness energy from the wind and a droplet-based energy generator (DEG) to collect energy from falling raindrops. Both the collectors were created in a visually appealing leaf shape for this particular application. 🍀 The TENGs consist of a layer of nylon nanofibers sandwiched between layers of polytetrafluoroethylene, more commonly known as Teflon. When the layers were pressed against one another by the force of wind, static charges were generated and converted into electricity by integrated copper electrodes. 🍀 On the other hand, the textile droplet-based electricity generator was also made from Teflon, with waterproofed electrodes made of a conductive fabric. As raindrops hit one of the electrodes, it creates an imbalance in charges and generates a small current and high voltage. 🍀 Under optimal conditions, the optimized TENG part of the device can produce 252 volts during contact mode mechanical excitations, and the DEG could generate 113 volts from waterdrops. 🍀 The team tested collectors of both types by incorporating their leaf-shaped versions into an artificial plant. When exposed to conditions mimicking natural wind and rain, the leaf-shaped generators produced enough electricity to power 10 LED lights in short flickers. 🍀 The researchers state that this proof-of-concept “power plant” device could be further developed into larger systems or networks of power plants to produce clean energy from natural sources. #energyticslimited #renerableenergy #energyefficiency #energyinnovation #windenergy #powerplant

I am honored to share our recent publication in Nature Communications titled “Effect of solid-electrolyte pellet density on failure of solid-state batteries.” In this work we investigate the critical challenge of Li-filament penetration in solid-state batteries (SSBs). We reveal Li-filament growth suppression in solid-electrolyte pellets, with a relative density exceeding ~95%, mitigates the risk of short circuits. By quantifying microstructural properties and employing modelling techniques, the study provides valuable insights into failure modes of SSBs, offering guidelines for the design of dendrite-free solid-state batteries to enhance safety and performance.
