Spectral Selective and Low‐Noise Thin‐Film Organic Photodetectors Enabled by Electric‐Field Engineering

Advanced Materials, EarlyView.
Molecular doping redistributes the internal electric field in organic photodetectors, providing a new degree of freedom to spatially control carrier transport and collection. Simulations and experiments reveal distinct transport pathways for injected and photogenerated carriers, enabling low dark current under reverse bias and wavelength‐selective ...

The grazing paradox: assessing contradictions of continuous versus rotational grazing systems in southern Africa

African Journal of Range & Forage Science
Unsustainable grazing practices result in degradation of arid and semiarid rangelands in southern Africa. Continuous grazing systems are often blamed for degradation, while rotational grazing systems are seen as more sustainable. The discussion about the impact of these grazing practices also has political and societal dimensions: continuous grazing is

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

Advanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Cattle grazing on semi-natural pastures [PDF]

, 2010
The knowledge of the grazing behaviour of cattle on Swedish semi-natural pastures and how this relates to the nutritional quality and quantity of the vegetation is low. In a situation where farming is being intensified both nationally and globally, it is

Comportamento ingestivo de ovelhas e cordeiras em pastagem de azevém-anual sob níveis crescentes de suplementação Ingestive behavior of ewes and ewe lambs on Italian ryegrass pasture under increasing supplement levels

Revista Brasileira de Zootecnia, 2008
Avaliou-se o comportamento ingestivo de ovelhas em lactação e cordeiras nos períodos pré e pós-desmama recebendo quatro níveis de suplemento (0; 0,5; 1,0 ou 1,5% do peso vivo), mantidas em pastagem de azevém (Lolium multiflorum Lam.) sob pastejo contínuo,

THE CONTINUOUS AND IMPULSIVE GRAZING MODEL IN A SAHELIAN REGION

International Journal of Advanced Research
Pastoralism in the Sahel plays a major role in the economy of West African countries. With a wide diversity of livestock species, it contributes to the food and nutritional security of rural and urban households. So, for reasons of survival, the shepherd can harvest from the herd population.
