Internal physiological drivers of leaf development in trees: Understanding the relationship between non‐structural carbohydrates and leaf phenology

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1151-1164, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

On the Damage Tolerance of Diffusion Bonded Titanium–Aluminum Phase Biomimetic Composites

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The biomimetic design principles of natural structures involve the strategic integration of stiff and compliant phases to synergistically enhance strength and toughness. Its evolutionary refined natural armor, characterized by a specialized microarchitecture, enables superior damage tolerance.

Blockchain and Quantum Technologies for Securing the Global Nuclear Supply Chain: Synergies, Applications, Technical Challenges and Opportunities

open access: yesJournal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.
ABSTRACT The infiltration of counterfeit, fraudulent, and suspect items into civil nuclear supply chains, notably within power generation and medical isotope production, poses severe safety and security threats. The ever‐increasing growth in nuclear installations (70 power plants are under construction and another 100 are in the planning stage) and the

Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.

晋西黄土区不同密度刺槐林土壤入渗特征及其影响因素

open access: yesShuitu Baochi Xuebao, 2020
为研究林分密度对土壤入渗性能的影响,以晋西黄土区5种密度(1 075,1 300,1 575,1 800,2 150株/hm2)刺槐(Robinia pseudoacacia Linn.)林为研究对象,采用双环入渗法测定其土壤入渗过程,并对入渗特征指标与土壤理化性质的相关性进行分析。结果表明:(1)不同密度刺槐林土壤入渗过程的变化规律一致,均经过瞬间入渗(0~5 min)、缓慢入渗(5~40 min)和稳定入渗(40 min后)阶段。(2)土壤初始入渗速率、稳定入渗速率 ...

工程堆积体入渗特征及入渗模型适宜性评价

open access: yesShuitu Baochi Xuebao, 2018
以重庆市城镇建设和交通枢纽工程形成的典型工程堆积体为研究对象,采用野外双环入渗法对工程堆积体入渗特征、影响因素及入渗模型适宜性进行研究,筛选重庆市典型工程堆积体最优入渗模型。结果表明:(1)工程堆积体初始入渗率可达23.20 mm/min,随着入渗时间的延长,入渗速率逐渐降低,30 min瞬时入渗率为2.38~11.32 mm/min,稳定入渗率为1.81~9.05 mm/min;(2)工程堆积体的初始入渗率、稳定入渗率、平均入渗率、30 min入渗率、60 min入渗率和渗透总量均表现为中等变异 ...

石漠化区退耕驱动下露石岩-土界面土壤渗透特性变化

open access: yesShuitu Baochi Xuebao, 2022
为揭示退耕对石漠化区露石岩—土界面土壤渗透特性的影响,以典型石漠化坡耕地为对照,选择休闲地、退耕灌草和果园为研究对象,采用环刀法研究了平直、外凸和内凹型露石岩—土界面土壤渗透特性。结果表明:(1)不同退耕类型岩—土界面土壤入渗过程及特征差异较大,从初始入渗率到稳定入渗率衰减幅度在0.350~55.756 mm/min,而不同岩—土界面形状间土壤入渗速率差异较大;(2)不同退耕类型岩—土界面土壤入渗速率的主要影响因素为毛管孔隙度和非毛管孔隙度,初始入渗率、平均入渗率和稳定入渗率均与毛管孔隙度呈极显著负相关(

The Two Faces of Introgression in Conservation Biology 基因渗入在保育生物学中的双重面貌

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 339-344, September 2025.
Conservation biologist need to take into account the various aspects of introgression in their attempts to protect the species integrity and evolutionary potential of threatened species. To do so, they have to overcome the bias created by the Mayrian species concept that considers species as having distinct gene pools.

A novel approach for feline sporotrichosis pathogen detection based on loop‐mediated isothermal amplification

open access: yesVeterinary Dermatology, Volume 36, Issue 4, Page 474-484, August 2025.
Background – Sporotrichosis is a chronic, mycotic infection caused by fungi of the genus Sporothrix. Zoonotic sporotrichosis occurs mainly through S. brasiliensis transmission, resulting from the organism's traumatic introduction via scratches or bites, or contact with exudate from contaminated cats.
