Ultrasound‐Driven Dual Piezocatalytic–Electrical Scaffold Synergistically Promotes Osteoporotic Bone Healing

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The regeneration of osteoporotic bone defects is severely hampered by compromised endogenous healing capacity, demanding advanced strategies that actively orchestrate pro‐osteogenic microenvironments. Here, we report an integrated, self‐powered osteo‐regenerative system that uniquely leverages a dual ultrasound‐responsive piezoelectric ...

Flexible, Robust Transparent Conductive Films With Excellent Electromagnetic Shielding Properties

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Transparent conductive films (TCFs) are indispensable components for next‐generation wearable electronics, intelligent robots, and electromagnetic interference (EMI) shielding devices. However, the fabrication of conventional random metallic mesh suffers from an inherent trade‐off between “randomness and controllability”.

From Crisis to Resilience: Rethinking Urban Flooding and Groundwater Recharge in Bengaluru City, India

open access: yesWorld Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Bengaluru, a primary metropolitan centre in India, is currently grappling with the dual crises of urban flooding and severe groundwater depletion. These challenges are driven by rapid urbanization, which has seen built‐up areas increase from 42% to 86% over two decades, resulting in a dramatic loss of vegetation and wetlands.

Oxygen‐Vacancy‐Enriched Ho/Yb/Sm‐Doped In2O3 With Reconfigured Electronic Structure for Highly Selective Ethylene Glycol Sensing

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT In this work, In2O3 and three rare earth (RE)‐doped In2O3 composites (Ho, Yb, and Sm‐doped) were prepared via the hydrothermal method. Compared with In2O3 sensors, those fabricated from the three composite materials (RE–In2O3) exhibit varying degrees of enhanced response toward ethylene glycol (EG) gas. At 35% relative humidity (RH) and 250°C,

Synergistic Enhancement of Toluene Catalytic Oxidation via Pt‐Induced Oxygen Vacancies and Heterojunction Built‐In Electric Field

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Improving catalytic activity for volatile organic compounds (VOCs) oxidation and enhancing water‐tolerance stability remain challenging in practical applications. Herein, a composite catalyst integrating Pt/CoOx‐NiOx mesoporous nanorods (MNRs) with a phenyltriethoxysilane (PhTES)‐modified surface was fabricated via a facile route for toluene ...

Hierarchical VO2@BiVO4 Films Decorated With Porous BiVO4 Nanoplates for Durable and Self‐Cleaning Smart Windows

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT VO2 is a promising thermochromic material, but it is still limited by low transparency, weak solar modulation, and poor stability. Here, we develop a coordination‐compound‐derived strategy to construct a hierarchical BiVO4/VO2@BiVO4 film with a core–shell@nanosheet structure.

Wings of Change: Motivations, Challenges, and Environmental Concerns Among Birdwatchers 变革之翼:观鸟者的动机、挑战与环境关切

open access: yesWildlife Letters, Volume 4, Issue 2, Page 83-93, June 2026.
Birdwatching in Nepal has high potential to support avain biodiversity and tourism. Conservation was identified as the primary motivation for birdwatching, followed by enjoyment and achievement purposes. Health/wellbeing benefits, social and economic factors showed moderate representation, whereas academic motivation played a relatively minor role ...

夏季晴天沼泽湿地贴地气层气温和相对湿度日变化特征

open access: yes, 2009
2008年68月在洪河国家级自然保护区沼泽湿地015 m贴地气层内,进行了6个高度的气温和相对湿度的野外定位观测。根据实测数据,分析了夏季晴天沼泽湿地贴地气层的气温和相对湿度的日变化特征。结果表明,夏季晴天沼泽湿地贴地气层内,气温日变化曲线为单峰型曲线,各高度的日最高气温和日最低气温分别出现在14∶00和03∶00,日平均气温和气温日较差都随高度递减。气温廓线有夜间辐射型、早上过渡型、白天日射型及傍晚过渡型4种分布类型。夏季晴天,0.515 m的日平均气温直减率为0.10℃/m ...

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.

融雪期土壤湿度与土壤温度、气温的关系

open access: yes, 2008
以天山北坡军塘河流域为研究区,利用2006年融雪期观测的土壤湿度和土壤温度及气温资料,分析土壤湿度在融雪期的变化情况以及与土壤温度和气温之间的关系,对观测期内10 cm深处的土壤日平均湿度与日平均温度关系进行了拟合,得出回归方程并通过了0.05的显著性检验;对观测期内雪面以上20 cm的日平均气温与10cm深度土壤日平均湿度进行了相关性分析(R=0.78),结果表明,两者之间具有较高的相关性。用比较容易取得的雪面气温与土壤湿度建立关系,或者能够解释土壤内部湿度大致情况 ...
