Thermochromic materials are substances that change color in response to temperature variations. Today, sustainability concerns the main drivers of thermochromic research, with smart, energy-efficient windows being one primary applications. While vanadium oxides and leuco dyes traditionally materials, hydrogels operating based on solvation have risen as some most promising due their high optical transparency good solar modulating abilities. In this work, a distinct mechanism for...
Polyethylene glycol (PEG) is widely used as phase change materials (PCM) due to their versatile working temperature and high latent heat. However, the low molecular weight of PEG prevents from formation flexible microfibers, common leakage problem associated with solid-liquid PCM further hinders applications in various fields. To address these challenges, polyethylene oxide (PEO) incorporated supporting matrix for PEG, leading a successful electrospinning fibrous mats. Due similar chemical...
Multiferroic ceramics with the general formula (x)MgFe2O4–(1−x)BaTiO3 (x=0.4, 0.5, and 0.6) were synthesized by solid-state sintering process. From x-ray diffraction analysis, it was observed that almost no chemical reaction occurs between ferrite ferroelectric materials used to form diphase composite systems. No impure phase in all sintered Leakage current density, properties dielectric found improve addition of phase. For least amount ferrite, values remnant polarization (2Pr) before after...
Abstract Controlling how a material interacts with light is key to optimizing its optical properties fit desired function or application. The most straightforward approach chemically physically modify the surface exposed incident light. An effective method of modification based on addition core‐shell structures at surface. Of particular importance many technological applications are dimensions comparable wavelengths extending from UV up near‐IR region electromagnetic spectrum, which...
Stimuli-responsive liquid marbles for controlled release typically rely on organic moieties that require lengthy syntheses. We report herein a facile, one-step synthesis of hydrophobic and oleophobic TiO2 nanoparticles display photoresponsive wettability. Water stabilized by these particles were found to be stable when shielded from ultraviolet (UV) radiation; however, they quickly collapsed after being irradiated with 302 nm UV light. Oil- organic-solvent-based could also fabricated using...
ABSTRACT Protein surface concentrations in emulsions stabilized by α‐lactalbu‐min (α‐la), β‐lactoglobulin (β‐lg) and their mixture were studied with various amounts of oil‐soluble surfactant present during homogenization. Three different surfactants considered: diethyl glycol n‐dodecyl ether (C 12 E 2 ), sorbitan monooleate (Span 80), glycerol monostearate (GMS). In n‐tetradecane‐in‐water emulsions, low con‐centrations C or Span 80 resulted a smaller average droplet size greater total...
Carbon–SnO2 core–shell hybrid nanofibers were prepared via single-spinneret electrospinning and subsequent heat treatment. The Kirkendall effect during the treatment is found to be responsible for formation of morphology. route proven generic fabrication carbon–metal oxide or nanofibers, corresponding nanotubes.

Precise control over the composition of heterostructure nanocrystals and their self-assembly is an emerging research interest. Superstructures this type are typically enhanced in terms collective functionalities. Herein, we developed a practical yet simple approach to synthesize self-assemble Cu2–xS/CuYS (Y = In, Sb, Sn) heterostructured nanorods (NRs) into vertically standing up assemblies. First NRs come together via depletion–attraction forces, then partial cation exchange between Cu31S16...
