Using electrospinning technique, well-aligned poly(azo-ether-imide) (PAEI) nano-fibers and PAEI/multiwalled carbon nanotube (MWCNT) nano-fibers were developed in this effort. Afterwards, polystyrene-b-poly (ethylene-ran-butylene)-b-polystyrene (SEBS) and polyimide-based nano-fiber films were casted. The as-prepared electrospun nanofibers acted as homogeneous reinforcement to enhance the tensile...

This study proposes a method for improving the estimation of surface turbulent fluxes in surface energy balance system (SEBS) model under water stress conditions using MODIS data. The normalized difference water index (NDWI) as an indicator of water stress is integrated into SEBS. To investigate the feasibility of the new approach, the desert-oasis region in the middle reaches of the Heihe Rive...

Banana fiber (BaF)-filled composites based on high density polyethylene (HDPE)/Nylon-6 blends were prepared via a two-step extrusion method. Maleic anhydride grafted styrene/ethylene-butylene/styrene triblock polymer (SEBS-g-MA) and maleic anhydride grafted polyethylene (PE-g-MA) were used to enhance impact performance and interfacial bonding between BaF and the resins. Mechanical, crystallizat...

The development of different energy balance models has allowed users to choose a model based on its suitability in a region. We compared four commonly used models—Mapping EvapoTranspiration at high Resolution with Internalized Calibration (METRIC) model, Surface Energy Balance Algorithm for Land (SEBAL) model, Surface Energy Balance System (SEBS) model, and the Operational Simplified Surface En...

Staphylococcus aureus produces superantigens (SAgs) that bind and cross-link T cells and APCs, leading to activation and proliferation of immune cells. SAgs bind to variable regions of the β-chains of T cell receptors (Vβ-TCRs), and each SAg binds a unique subset of Vβ-TCRs. This binding leads to massive cytokine production and can result in toxic shock syndrome (TSS). The most abundantly produ...

Sulfonated styrene-(ethylene-butylene)-styrene triblock copolymer (SSEBS) was synthesized by reaction of acetyl sulfate with SEBS. SSESB-clay nanocomposites were then prepared from hydrophilic Na-montmorillonite (MT) and organically (quaternary amine) modified hydrophobic nanoclay (OMT) at very low loading. SEBS did not show improvement in properties with MT-based nanocomposites. On sulfonation...

In this study, eight binary blends of polypropylene (PP)/ poly [styrene-b-(ethylene-co butylene)-b-styrene] tri-block copolymer (SEBS) and polypropylene (PP)/ polycarbonate (PC) were produced at different composition through twin screw extruder. The composition of the minor phases was changed to correlate the morphology and mechanical properties of binary blends (PP/PC and PP/SEBS) through ther...

We propose a long-term parameterization scheme for two critical parameters, zero-plane displacement height (d) and aerodynamic roughness length (z0m), that we further use in the Surface Energy Balance System (SEBS). A sensitivity analysis of SEBS indicated that these two parameters largely impact the estimated sensible heat and latent heat fluxes. First, we calibrated regression relationships b...

فرضیه: در سال‌های اخیر، با توجه به موضوع‌های آلودگی زیست‌محیطی، صنایع پلاستیک به مصرف پلاستیک‌های زیست تخریب‌پذیر تشویق شده‌اند. پلی‌(لاکتیک اسید)، PLA، از شناخته‌شده‌ترین پلیمرهای زیست‌تخریب پذیر با برتری ماهیت زیست‌پایه است. عیب اصلی PLA شکنندگی ذاتی آن بوده که آمیخته‌سازی مناسب‌ترین روش برای غلبه بر آن است. روش‌ها: PLA بسیار چقرمه از کوپلیمر اتیلن-وینی...
