Sodium metal batteries have garnered significant attention due to their high theoretical specific capacity, cost effectiveness, and abundant availability. However, the propensity for dendritic sodium formation, stemming from highly reactive nature of surface, poses safety concerns, uncontrollable formation solid–electrolyte interphase (SEI) leads large cell impedance battery failures. In this study, we present a novel approach where successfully developed stable fluorinated artificial SEI...
Li 10 GeP 2 S 12 (LGPS) is a superionic conductor that has an ionic conductivity matching conventional liquid electrolytes (10 −3 cm −1 ) and thus shows exceptional potential to fulfill the promise of solid-state metal batteries. Conventional mechanical die pressing LGPS powder into pellets for electrochemical testing can result in large porosity, low density, grain boundary resistance at solid-solid interface with electrodes which greatly decrease performance LGPS, addition poor stability...
Pressed LGPS pellets after cycling in contact with Li metal. 20 nm of ALD LiPON deposited directly onto the allows longer lifetimes (in this case, 90 cycles) at reduced overpotential than bare LGPS, which fails 64 cycles.
FeF3 (iron(III) fluoride) is a promising conversion cathode material that possesses theoretical specific capacity of 712 mAh/g, which significantly higher than those commercial layered cathodes, and it paves the way for realizing Co-free, low-cost advanced batteries portable electronics, transportation, grids. Here, we report development thin-film cathodes by sputtering deposition technique. The chemistry stoichiometry sputtered thin films are confirmed energy-dispersive X-ray spectroscopy...
Lithium metal anode batteries have attracted significant attention as a promising energy storage technology, offering high theoretical specific capacity and low electrochemical potential. Utilizing lithium the material can substantially increase density compared to conventional lithium-ion batteries. However, practical application of anodes has encountered notable challenges, primarily due formation dendritic structures during cycling. These dendrites pose safety risks degrade battery...
In the face of mounting global energy requirements and pressing environmental issues, scientific community turned to lithium-metal batteries, celebrated for their superior capacity efficiency. However, challenges arising from scarcity increasing costs lithium have redirected research efforts towards sodium batteries. Sodium metal anodes, with remarkable theoretical specific ~1166 mAh/g, low anode potential -2.714 V vs standard hydrogen electrode, cost benefits, are increasingly recognized as...
A highly uniform Na 3 N-rich SEI layer, formed by nano-sized Si N 4 , drastically improves sodium-metal battery performance enhancing stability, inhibiting dendrite growth, and extending cycling life to over 5.5× (>1100 hours).

Nowadays, ensuring information security is extremely inevitable and urgent. We are also witnessing the strong development of embedded systems, IoT. As a result, research to ensure for software being focused. However, studies on optimizing multi-core processors increase performance have not received much attention. The paper proposes develops improvement method based data partitioning asynchronous processing. Data used globally be retrieved by any threads. divided into different partitions,...
Perspectives on a water system and its management determine how problems are defined which types of solutions preferred. When developing strategies, it is therefore important to understand different perspectives that exist amongst actors. Additionally, may change over time. This implies the dynamics need be considered able meet demands future. Building Offermans (2012), we study in Vietnamese Mekong Delta as first step towards more sustainable strategies this region. To gain insight...
Vermiculite (VER) is a type of clay mineral abundant in reserves, with low cost and environmental friendliness. There are many chemicals used to expand VER such as HCl, H2SO4, etc. In this study, vermiculite was expanded using mixed methods microwave irradiation H2O2. Factors affecting the expansion process minerals VER:H2O2 ratio, H2O2 concentration, drying temperature, time, soaking time were investigated optimized. material determined be optimally at ratio 1:6, 30% for 60 minutes, °C...
