Synthesis of Core–Shell Te@Se Quantum Dots and Their Broadband Photodetector Performance in Low Concentration Electrolytes

Laser &Photonics Reviews, EarlyView.
Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.

Effect of outdoor production, slurry management and buffer zones on phosphorus and nitrogen runoff losses from Finnish cattle farms [PDF]

, 2010
This thesis sums up studies on phosphorus (P) and nitrogen (N) losses to water from forested feedlots and slurry-amended grass fields. Moreover, different ways of mitigating the losses in a boreal climate are discussed.

Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site

Oikos, EarlyView.
Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...

Influence of alloy composition on wear behavior of high-Cr white cast irons for chute linings

Journal of Engineering and Applied Science
This study compares the wear resistance of three experimental high-chromium white cast iron (HCWCI) alloys with varying chromium content (20.2–24.5 wt%) and carbide morphologies for mining applications.

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

Polymer Composites, EarlyView.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

Experimental Study on Performance of Modified Cement-Clay Grouting Materials in Dynamic Water Environments

Renmin Zhujiang
Grouting technology is a crucial method for mitigating karst water inrush disasters. However, traditional grouting materials have obvious limitations in dealing with high-pressure and high flow dynamic water environments, such as poor anti-dispersion ...

Permafrost Mass Wasting in Ice‐Rich Landscapes: Recent Advances (2013 to 2024) on Mechanisms, Dynamics and Impacts

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

Cryostratigraphy of Rhythmic Segregated Ice in Colluvium and Implications for Permafrost Slope Stability

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

Incorporating soil biological and functional attributes to advance ecological restoration

PLANTS, PEOPLE, PLANET, EarlyView.
Earth is currently experiencing a mass extinction crisis, predominantly driven by anthropogenic activities, with land use change causing widespread loss and degradation of native ecosystems and indigenous species. There is an urgent need to halt this trend and restore degraded habitat to preserve biodiversity and protect threatened plants and animals ...
