Carbon Nanorods With Adhered Monodisperse Cobalt Nanoparticles Exhibiting Electromagnetic Wave Absorption and Antibacterial Potential

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Magnetic particles coated with carbon shells have been considered as promising electromagnetic wave absorption materials with antibacterial features. However, how to precisely control the monodispersed magnetic nanoparticles on a carbon matrix to manipulate impedance matching and antibacterial performances is still a key challenge.

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

VO2 Hollow Nano‐Reactor: Enabling Near‐Room‐Temperature and Ultrafast Hydrogen Release From α‐AlH3

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT α‐phase aluminum trihydride (α‐AlH3) is a promising high‐capacity hydrogen storage material, but its practical application is limited by slow dehydrogenation kinetics and high reaction temperatures. This study demonstrates, for the first time, effective modulation of the hydrogen release kinetics of AlH3 by employing a hollow nanostructured ...

Chemical Removal of Al From Layered Mn2AlB2: Toward 2D‐MBene and Its Application to MgH2 Hydrogen Storage

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Two‐dimensional Mn‐based MBenes remain challenging to synthesize due to structural instability during etching. Herein, Mn2AlB2 was employed as a precursor to systematically investigate Al removal via HF, NaOH, and a gas–solid route using PVDF‐derived HF.

Predictive M‐Site Design of MAX‐Derived CoNi Composites: Dual‐Scale TaC + L12 Strengthening Enabled by Rare Metal Ta

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT In MAX‐phase‐derived metal–matrix composites, the M‐site element simultaneously governs carbide chemistry and matrix precipitate stability, yet it has traditionally been selected empirically rather than from a predictive criterion linking M‐site choice to carbide chemistry, matrix alloying, and L12 stability; moreover, the reaction pathway ...

模拟增温对川西亚高山两类针叶林土壤酶活性的影响

open access: yes, 2010
采用开顶式生长室(open top chamber,OTC)模拟增温,同步监测了亚高山人工针叶林和天然针叶林表层土壤温、湿度的变化,以及模拟增温初期土壤转化酶、脲酶、过氧化氢酶和多酚氧化酶活性的变化.结果表明:在整个生长季节中,OTC使人工林和天然林5cm土壤日平均温度分别增加0.61℃和0.56℃,10cm体积含水量分别下降4.10%和2.55%;模拟增温增加了土壤转化酶、脲酶、过氧化氢酶和多酚氧化酶活性.增温与林型的交互作用对土壤脲酶和过氧化氢酶活性有显著影响,而对转化酶和多酚氧化酶影响不显著 ...

Synchronous Ultrasonic Impact Treatment for Regulating Microstructure and Properties of Laser‐Directed Energy Deposited In Situ TiC/Ti6Al4V Composites

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT In laser‐directed energy deposition (LDED) of TiC/Ti6Al4V composites, a low content of micron‐sized TiC provides a good strengthening effect on hardness and strength, but the improvement in plasticity remains a challenge. By introducing synchronous ultrasonic impact treatment (UIT) into the LDED process, an ultrasonic‐assisted LDED (UA‐LDED ...

Multi‐gradient warming reshapes functional traits and adaptive responses of alpine meadow plants

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2889-2905, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional traits in alpine meadows are critical indicators of ecosystem responses to climate warming, yet dynamic changes in trait networks across warming gradients and their consequences for community functions remain poorly understood.

Changes and regularities of organic matter mineral pore in fine-grained sedimentary rocks during temperature rise: A case study of fine-grained sedimentary rocks in kong 2 member of Cangdong sag(细粒沉积岩有机质-矿物-孔隙在升温过程中的变化及其规律)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2023
在埋藏过程中,随着埋深的增加,细粒沉积岩的矿物组成、有机质形态、孔隙类型与质量分数等会发生一系列变化。为揭示其变化规律,对有机质热模拟的残样进行了扫描电镜、全岩X射线衍射、镜质体反射率(Ro)、岩石热解、有机碳质量分数等测试。发现在从室温(25 ℃)到550 ℃的升温过程中,有机质形态由团块状向条带状、团块状变化;黏土矿物由层片状逐渐向絮状转化;碳酸盐矿物溶蚀加剧,温度超过500 ℃后,出现溶蚀-沉淀现象;随着温度的升高,由有机质热演化产生的有机质孔的面积不断增加,在450~475 ℃时 ...
