Thermochromic smart windows effectively reduce the energy consumption for buildings through passive light modulation including the transmission ofvisible(TVis)and near-infrared(TNIR)light,and the emissivity of mid-infrared light(εMIR)in response to ambient temperature ***,thermochromic windows that maintain high TVis while modulating TNIR and εMIR simultaneously are highly desirable but still ***,we develop a thermochromic smart window based on a two-way shape memory polymer to enable reversible transformation and achieve TNIR modulation of 44.0％andεMIR modulation of 76.5％while maintaining high TVis(＞50％).Compared to traditional windows based on silica glass,this device shows 4℃ lower temperature in summer daytime,2℃ higher in winter daytime,and 1℃ higher in spring *** is expected that our device can achieve greater annual energy savings in comparison with commercial glass anywhere in the world and promote the progress of thermochromic windows for energy-efficient buildings.

Food and dairy processing industries consume large quantities of clean water for various processes throughout the plant operations and consequently generate large amounts of wastewater. The objective of this study is to treat the wastewater of food and dairy industries using ZnO nanoparticles (ZnO NPs) to control the pH level and reduce contamination levels. The wastewater from three industries was tested for pH, total dissolved solids (TDS), turbidity, Chemical Oxygen Demand (COD), and Biochemical Oxygen Demand (BOD). The ZnO NPs are prepared with an average size of less than 100 nm by using a simple precipitation method. The obtained particles were characterised by X-Ray Diffraction (XRD), and Scanning Electron Microscope (SEM) proving the nano size of Zinc Oxide nano particles. The effluents have been treated with the ZnO NPs by varying doses resulting in reducing all contaminants to an acceptable level as recommended by concerned environmental organisations. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

Sulfonation of HwBKP by Sulfur Trioxide Pyridine Complex and Preparation of Anionic Cellulose Beads Using the Same

To expand the applications of cellulose beads, sulfonated cellulose beads were prepared by chemically modifying HwBKP fibers with sulfur trioxide pyridine complex (STP), dissolving in tetraethylammonium hydroxide (TEAOH)/urea solvent, and dropping into acetic acid solution. The effect of the amount of STP added on the properties of sulfonated cellulose solution and cellulose beads was investigated. It was observed that the sulfonated cellulose beads exhibited anionic surface charge in a fairly wide pH range, and the degree of substitution of sulfonic acid groups and the zeta potential of the cellulose beads could be controlled by adjusting the amount of added STP. In addition, as the amount of STP added increased, the crystallinity of the cellulose decreased, the viscosity and surface tension of the sulfonated cellulose/TEAOH/urea solution decreased, and the size of the cellulose beads increased. © 2023 Korean Technical Assoc. of the Pulp and Paper Industry.

Optimizing large optical contrast in Ge-Se-Te films via high-throughput method

Chalcogenide phase-change materials（PCMs） have attracted great attentions due to their potential applications in reconfigurable photonic devices. The Ge2Sb2Te5and GeTe PCMs exhibit significant difference in refractive index（Δn） between amorphous and crystalline states, but they suffer from high optical loss. The binary Sb2S3and Sb2Se3PCMs, however, show low optical loss but small Δn. This encourages us to develop the novel materials,which are desired to combine large Δn and low optical loss. Instead of traditional trial-and-error screening method, we here used an efficient high-throughput method to optimize the PCMs' candidates for reconfigurable photonic devices in Ge-Se-Te chalcogenides. The crystallization temperature and difference in optical bandgap were detected, and then the component of Ge25Se7Te68, which also exhibits ultralow optical loss of 1.2 × 10-6（in amorphous state） and large Δn of 1.32 at 1550 nm, was optimized. This Te-rich Ge-Se-Te film can be a candidate for the applications of programmable reconfigurable photonic circuits.
