Improving the Electrochemical Properties of SiOx/Graphite Anode for High‐Performance Lithium‐Ion Batteries by Ultrathin Lithium Film Prelithiation

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT High‐capacity SiOx/graphite (SiO/G) anodes offer great potential for advancing lithium‐ion battery technology; however, their practical application is limited by low initial coulombic efficiency (ICE) and rapid capacity decay. These challenges primarily arise from unstable phase transitions and the formation of the solid electrolyte interphase

In Situ Formation of the Li3Bi Alloy Phase Interface for Robust Garnet Solid‐State Lithium Batteries

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Garnet‐type electrolyte Li6.4La3Zr1.4Ta0.6O12 (LLZTO) is a promising component for commercializing solid‐state batteries owing to its wide electrochemical window, good stability, and high shear modulus. However, poor interface wettability and lithium dendrite growth limit the practical application of the LLZTO electrolyte.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.

open access: yesNew Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

DLC film prepared with multiple gas sources and its applications [PDF]

open access: yes, 2016
类金刚石膜(Diamond-LikeCarbon,DLC)是一种介于金刚石和石墨之间的非晶结构材料。类金刚石膜具有和金刚石类似的许多独特的优良性能,因此被广泛应用在机械、光学、电学以及生物等领域。 等离子体化学气相沉积(PECVD)法是生长含氢DLC膜的常见方法,通常把衬底放在PECVD腔体中的源电极上生长DLC薄膜,这样生长的DLC膜具有更高的硬度。本文采用浸入式PECVD方法生长DLC薄膜,把衬底浸入到等离子体中,使其面临的电场强度和离子团密度等生长参数有别于源电极式PECVD法 ...

等离子体气动激励器布局对加速效应影响的实验研究

open access: yesGaoya dianqi, 2010
等离子体气动激励器作为等离子体流动控制的执行元件,其性能优劣对流动控制效果有重要影响。诱导气流速度是表征等离子体流动控制能力、衡量等离子体气动激励器性能的一个重要指标。研究了等离子体气动激励器的电极宽度、厚度、电极组内间距、绝缘材料介电常数和厚度等布局参数对诱导气流速度的影响。实验结果表明:选择介电常数合适、尽可能薄的绝缘材料,宽度较大、尽可能薄的条状电极,电极组内间距为1 mm左右的等离子体气动激励器,可提高等离子体气动激励诱导的气流速度。
