Mixed‐Impurity Co‐Poisoning of NH3‐SCR Catalysts: Poisoning Mechanisms, Antagonistic Effects, and Anti‐Inactivation Strategies

EcoEnergy, EarlyView.
This review summarizes the synergistic effects of mixed impurities on ammonia‐selective catalytic reduction (NH3‐SCR) catalysts, including the poisoning mechanism of the catalyst caused by mixed impurities, the antagonistic effects between the impurities, and the research on the anti‐poisoning strategies for the catalyst in recent years.

Assessing the use of rainfall synthetic series to estimate rainfall erosivity in Brazil

CATENA, 2018
Although it has been used in research or technical work, applying synthetic rainfall data series to estimate rainfall erosivity is still a tool that requires careful evaluation and validation. In this study we evaluate the potential use of synthetic data

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

Ecography, EarlyView.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Discovering historical rainfall erosivity with a parsimonious approach: A case study in Western Germany

, 2017
An in-depth analysis of the interannual variability of storms is required to detect changes in soil erosive power of rainfall, which can also result in severe on-site and off-site damages.

Thermochromic Radiative Cooling Coatings with Robust Superhydrophobicity for Energy‐Efficient Buildings

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable, color‐adaptive radiative cooling coating is developed to enable dynamic spectral regulation via a reversible thermochromic transition at ~45 °C and a high solar reflectance of 91.7%. The coating achieves 4.44 °C outdoor sub‐ambient cooling while providing robust superhydrophobicity and environmental durability through its micro/nano ...

Nature‐Based Solutions for Climate Adaptation: Review of Barriers to Adoption and Guidelines for Policymakers

Environmental Policy and Governance, EarlyView.
ABSTRACT Nature‐based solutions (NBS) for climate adaptation encompass a range of approaches that work with nature to increase resilience to climate change while providing ecological, economic and social co‐benefits. These solutions have frequently been put forward for application in urban contexts, such as the creation of urban forests, but can ...

Erosividade das chuvas em Uruguaiana, RS, determinada pelo índice EI30, com base no período de 1963 a 1991 Rainfall erosivity in Uruguaiana, Rio Grande do Sul, Brazil from 1963 to 1991 determined by the EI30 index

Revista Brasileira de Ciência do Solo, 2008
A erosividade representa o potencial que as chuvas têm de provocar erosão hídrica no solo. O índice EI30 é um método de determinação dessa erosividade das chuvas e é calculado, para cada chuva individual e erosiva, pelo produto da energia cinética total ...

Spatial and temporal variations of rainfall-runoff erosivity (R) factor in Kakheti, Georgia

, 2018
Soil erosion is a very complicated process. Rainfall erosivity is one of the main factors affecting on soil erosion. The erosive power of precipitation is accounted for by the rainfall erosivity factor (R-factor).

Bridging Cross‐Scale Science–Policy Interfaces for Coherent Land‐Use Governance: Knowledge Co‐Production and Uptake in Kenya's Polycentric System

Environmental Policy and Governance, EarlyView.
ABSTRACT Land is fundamental to livelihoods and ecosystem health but faces mounting pressure from human activities, climate change, and competing development demands. Science–policy interfaces (SPIs)—platforms that connect experts and policymakers—are vital for co‐producing knowledge to inform coherent, sustainable land‐use governance.
