Evapotranspiration (ET) plays an important role in the hydrological cycle and it is essential to estimate ET accurately for the evaluation of available water resources in arid regions. In this paper, the monthly change of ET in the semi-arid Hailiutu River basin in northwest China were studied. The spatial distribution of ET was assessed by using the energy balance approach SEBS (Surface Energy...

Poly(vinyl chloride) (PVC) and natural fiber composites were prepared by melt compounding and compression molding. The influence of fiber type (i.e., bagasse, rice straw, rice husk, and pine fiber) and loading level of styrene-ethylene-butylene-styrene (SEBS) block copolymer on composite properties was investigated. Mechanical analysis showed that storage modulus and tensile strength increased ...

Hybrid anion exchange membranes (AEMs) were prepared via chemically functionalizing and crosslinking poly(styrene-b-[ethylene-co-butylene]-b-styrene) (SEBS) copolymers low molecular weight homo-polystyrene (hPS). Via sequential chloromethylation, crosslinking, quaternization, alkalization, a series of hPS/SEBS AEMs obtained with varying content hPS. Systematic structural, morphological, mechani...

The inquiry-based learning model can facilitate students’ understanding of scientific concepts. Scientific epistemological beliefs (SEBs) are related to about the nature process knowledge in science education. However, whether “prediction-observation-explanation” (POE) fifth graders’ concept achievement and SEBs education has not been extensively studied. This study selected unit Light Refracti...

In spite of the well-established design and construction approaches slag–cement–bentonite slurry walls, materials deteriorate inevitably in contaminated land. The development effective which are sustainable, resilient self-healing over lifetime walls becomes essential. This study, for first time, adopts a styrene–ethylene/butylene–styrene (SEBS) polymer to modify enhance mechanical performance....
