Elementary Study on Gully Classification on the Qinghai-Xizang Plateau

open access: yesShuitu Baochi Xuebao
[Objective] Traditional gully classification systems focus on agricultural landscapes. However, on the Qinghai-Xizang Plateau, where human activity is limited, gullies primarily occur in natural landscapes.

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Critical evaluation of compost erosion control blankets (CECBs) against conventional best management practices (BMPs) for the prevention and control of soil erosion, nutrient loss and storm water runoff from engineered slopes under simulated UK conditions [PDF]

open access: yes, 2010
In recent decades increasing attention has been dedicated to issues of sustainable land management. Soil is essential for a number of functions and services which are central to the sustainability of agro-ecosystems and the global economy ...

Influence of landscape pattern changes on water conservation capacity: A case study in an arid/semiarid region of China

open access: yesEcological Indicators
With the accelerating changes of land use/cover caused by natural and human factors, landscape pattern has undergone significant changes. Given the scarcity of water resources and the degradation of ecological functions in arid and semi-arid regions of ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Comparison of an Automated and Manual Method for Calculating Storm Runoff Response in Ungauged Catchments in Serbia

open access: yesJournal of Hydrology and Hydromechanics, 2013
Estimation of discharge from ungauged catchments based on rainfall-runoff analysis is a very frequent task in engineering hydrology. Very often, design discharges are needed for streams or small rivers where no streamflow data is available (river ...

Cumulative effects of 20-year exclusion of livestock grazing on above- and belowground biomass of typical steppe communities in arid areas of the Loess Plateau, China

open access: yesPlant, Soil and Environment, 2011
Overgrazing affects typical steppe community in ways similar to grasslands in other areas. Exclusion of livestock grazing is one of the main management practices used to protect grasslands.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Bank erosion processes along the lower Mekong River

open access: yes, 2012
This project conducts an analysis of bank erosion processes on a large, monsoonaffected river, the Lower Mekong River in Laos. The methodological approach taken was to build integrated models of bank erosion processes at three study sites on the Lower ...
