Opportunities and barriers for promoting biodiversity in Danish beef production

iScience
Summary: Grazing at near-natural stocking rates is increasingly rare, whereas abandonment and overgrazing is common, despite both leading to loss of threatened species.

High‐Efficiency Precipitate Recycling Strategy Paves the Way for Efficient Sb2S3 Solar Cells Fabricated by CBD Method

Advanced Science, EarlyView.
A novel PR strategy was proposed to improve CBD‐derived Sb2S3 film quality. It synergistically optimized the CBO of CdS/Sb2S3 interface and the back‐contact barrier, while the VS2 donor defect was converted into SSb2 acceptor defect with lower concentration.

Climate Effects on Tallgrass Prairie Responses to Continuous and Rotational Grazing

Agronomy, 2019
Cattle grazing is an important economic activity in the tallgrass prairie systems in the Great Plains of the United States. Tallgrass prairie may respond differently to grazing management (e.g., high and low grazing intensity) under variable climate ...

Grazing Capacity, Sheep Gains: Cheatgrass, Bunchgrass Ranges in Southern Idaho [PDF]

Journal of Range Management, 1971
Comparisons were made of grazing capacities and sheep gains on both cheatgrass range and on native bunchgrass range during early spring. Capacities were similar on these two range types in wet years, but were almost 60% greater on bunchgrasss range during dry years. Sheep gained an average of 0.32 lb.

Optimized Antimony‐Doped Tin Oxide Thin Films With Enhanced Electrical Properties for Low‐Emissivity Architectural Coatings

Advanced Science, EarlyView.
Antimony‐doped tin oxide (ATO) thin films were deposited by aerosol‐assisted chemical vapor deposition (AACVD) and systematically investigated to establish correlations between Sb doping level, structural properties and optoelectronic performance. Optimized films exhibited low sheet resistance, high carrier concentrations, and high visible transparency

Theretofore Highest Efficiency in Vacuum‐Deposited Organic Solar Cells Originating From Triarylamine‐Based Small‐Molecule Donors Containing Fused Heterocycle Units

Advanced Science, EarlyView.
Fused‐ring engineering unlocks record efficiency in vacuum‐deposited organic solar cells. By replacing linear π‐bridges with fused‐ring analogues in triarylamine‐based donors, we achieve enhanced molecular planarity, red‐shift optical absorption, minimize energy loss and optimized phase separation.

Effects of warm-season feeding on yak growth, antioxidant capacity, immune function, and fecal microbiota

Microbiology Spectrum
The yak (Bos grunniens) is of great importance to the local ecosystem and animal husbandry on the Tibetan Plateau. However, the impacts of different feeding practices on yak growth, health, and ecosystem interactions are not fully understood.

In‐Situ Constructed Cations for 2D/3D Perovskite Heterostructure for Stable and Efficient Photovoltaics

Advanced Science, EarlyView.
An in‐situ spacer‐cation construction strategy is developed by inducing strong hydrogen bonding between n‐hexyl phosphonic acid (HPA) and FA+, forming a stable N‐type 2D/3D perovskite heterostructure. This approach suppressed defect formation, promoted electron transport, and improved intrinsic stability, delivering 26.32% PCE, excellent operational ...

Charge‐Transfer‐Mediated Boron Magneto‐Ionics: Towards Voltage‐Driven Multi‐Ion Transport

Advanced Science, EarlyView.
This study demonstrates voltage‐driven multi‐ion transport in FeBO systems, revealing simultaneous motion of B, Fe, and O ions enabled by charge‐transfer effects. By tuning oxidation states through oxygen incorporation, we achieve a transition from electrostatic‐like to electrochemical magneto‐ionic behavior. The findings establish boron magneto‐ionics,

Forage yield and grazing efficiency on rotationally stocked pastures of 'Tanzania-1' guineagrass and 'Guaçu' elephantgrass

Scientia Agricola, 2005
The potential carrying capacity of tropical pastures depends not only on the productivity of the forage species and the amount of forage on offer, but also on the efficiency with which the produced herbage is harvested by the grazing animal.
