PROPERTY RIGHTS, GRAZING PERMITS, AND RANCHER WELFARE [PDF]

open access: yes
This study attempts to link factors affecting the demand for Bureau of Land Management grazing to perceived changes in permittee welfare over the 1962-92 period. Annual demand for federal forage is found to be sensitive to active preference, beef cow and

Heteroatom‐Mediated Covalent Organic Framework Membranes With Nitrogen‐Enriched Nanochannels for Efficient Desalination

open access: yesAdvanced Science, EarlyView.
Heteroatom precursor engineering serves as a molecular‐level strategy to tailor hydrazide monomer reactivity and diffusion kinetics, enabling controlled assembly of highly crystalline COF membranes with ultramicroporous channels. The nitrogen‐enriched nanochannels deliver high water/ion selectivity via simultaneous water transport acceleration and ion ...

Chemical Fertilizer Reduction Combined with Microbial Fertilizer Improved Vegetation and Soil Characteristics in Degraded Alpine Meadows

open access: yesPlants
Alpine meadow degradation is a serious challenge for animal husbandry and ecosystem safety in the Qilian Mountain area, northwest China. Although some restoration methods have been used, fertilization practices still rely heavily on chemical fertilizers.

Ion‐Exchange‐Driven Ternary Organic Neuromorphic Devices with High Efficiency and Stability

open access: yesAdvanced Science, EarlyView.
Spontaneous ion exchange in a ternary polymer–ionic liquid blend disrupts the phase‐separated ionic domains of the binary film and creates a more homogeneous polymer–ion environment. This ionically reorganized matrix enables stable and efficient electrochemical doping, leading to ion‐gel‐gated organic electrochemical transistors with enhanced ...

Force‐Electric Nanotentacles of Tantalum Implant Accelerate Cellular Energy Metabolism/Crosstalk for Immunomodulation‐Vascularized Bone Integration

open access: yesAdvanced Science, EarlyView.
A biomimetic force‐electric nanotentacle‐enabled tantalum (Ta) implant with surface‐nanostructured LiTaO3 (n‐LiTaO3) was first developed via laser nanofabrication combined with Li+‐induced in situ reaction, enabling the transduction of ultrasound into bioelectrical cues.

Identifying Meat from Grazing or Feedlot Yaks Using Visible and Near-infrared Spectroscopy with Chemometrics

open access: yesJournal of Food Protection
The quality of meat can differ between grazing and feedlot yaks. The present study examined whether spectral fingerprints by visible and near-infrared (Vis-NIR) spectroscopy and chemo-metrics could be employed to identify the meat of grazing and feedlot ...

Increasing Rhizosphere Fungi and Improving Soil Quality with Biologically Effective Grazing Management [PDF]

open access: yes, 2004
This report compares the effects of traditional grazing management to twice-over rotation grazing management on livestock performance, herbage biomass, and rhizosphere fungal populations on Northern Plains native ...

Side‐Chain Asymmetry in Quinoxaline Copolymer Donors Enables Optimal Morphology and Improved Charge Dynamics for High‐Efficiency Organic Solar Cells

open access: yesAdvanced Science, EarlyView.
Side‐chain asymmetry in quinoxaline copolymer donors modulates donor–acceptor miscibility and blend morphology in all‐polymer solar cells. The asymmetric donor PBAQ6 enables more balanced charge transport, reduced recombination, and improved charge dynamics with PYF‐T‐o, delivering PCEs of 18.35% in binary devices and 19.52% in ternary devices ...

Deposition Rate‐Controlled Functional Evolution of p‐Type Selenium‐Alloyed Tellurium–Tellurium Oxide Films for Thin‐Film Transistors

open access: yesAdvanced Science, EarlyView.
This study investigates the effects of thermal deposition rate on next‐generation p‐type amorphous oxide semiconductor SeTe–TeOx films. Deposition rate governs the chemical states, microstructure, and electrical characteristics of the films, resulting in tunable device properties.
