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

open access: yesAdvanced 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 ...

Amorphous IGZO, Crystalline IGO, Amorphous IGZO Triple Active Layer With 2D Electron Gas at Both Interfaces for High Performance TFTs

open access: yesAdvanced Materials Technologies, EarlyView.
The dual‐gate coplanar a‐IGZO/C‐IGO/a‐IGZO TFT is investigated, exhibiting a high filed‐effect mobility of 53.81 cm2 V−1s−1 with excellent stability. The amorphous IGZO layer provides smooth surface, which carrier scattering and high‐quality interface between gate insulator and active layer.

Hydro‐ and Lipophilicity of Molecular‐Size‐Controlled Hydrogel Drug Carriers

open access: yesAdvanced Materials Technologies, EarlyView.
We investigate nano‐sized hydrogel drug carriers with tailored hydro‐ and lipophilicity. We design their encapsulation and structure‐forming capabilities and follow them in real time during fabrication using time‐resolved and in situ grazing incidence x‐ray scattering.

PUBLIC LAND POLICY AND THE VALUE OF GRAZING PERMITS [PDF]

open access: yes
This article provides an empirical test of the traditional theory of permit value and investigates the impact of recent changes in public land policies on the value of grazing permits.

Aboveground Net Primary Productivity in Grazed and Ungrazed pastures: Grazing Optimisation Hypothesis or Local Extinction of Vegetation Species [PDF]

open access: yes, 2009
The controversy that has surrounded herbivory studies in the last few decades prompted our investigation to establish the extent to which herbivore optimisation hypothesis or compensatory growth evidence is real.

Perspective: Hollow Core Optical Fibres for Ultraviolet and Visible Wavelengths

open access: yesAdvanced Science, EarlyView.
Hollow core optical fibres bypass material constraints that limit optical fibres at ultraviolet and visible wavelengths. However, their challenging fabrication has limited their development, and significant gains in performance remain possible. In this perspective we outline approaches to enable the next generation of fibres for shorter wavelengths ...

Operational strategies for optimizing grazing when using automatic milking systems in organic dairy production [PDF]

open access: yes, 2013
Successful grazing when using AMS is possible without having to devote a great deal of time to organize and fetch cows every day. However, a careful strategy and good infrastructure, and observation of cow behaviour and pasture are necessary, and the ...

Pasture-Based Dairy Systems: Who Are the Producers and Are Their Operations More Profitable than Conventional Dairies? [PDF]

open access: yes
U.S. dairy operations are sorted via a multinomial logit model into three production systems: pasture-based, semi-pasture-based, and conventional. Region, farm size, financial situation, and production intensity measures impact system choice.

Phase Diagrams and Piezoelectric Properties of Wurtzite Al1−x−yScxGdyN Heterostructural Alloys

open access: yesAdvanced Science, EarlyView.
This study demonstrates ferroelectricity and piezoelectric properties improvement of quaternary wurtzite Al1−x−yScxGdyN${\rm Al}_{1-x-y}{\rm Sc}_x{\rm Gd}_y{\rm N}$ films, guided by density functional theory calculations. Wurtzite Al1−x−yScxGdyN${\rm Al}_{1-x-y}{\rm Sc}_x{\rm Gd}_y{\rm N}$ films have a high optical bandgap, enhanced piezoelectric ...
