“…Among them ZnS is a chalcogenide semiconductor with a moderate band gap values ∼3.72 eV at room temperature [39] and it is most widely studied material because of low cost, non-toxicity and Ultra-Violet active photocatalyst towards dye degradation. Apart from the dye degradation, the ZnS is broadly used in various elds such as light emitting diode (LED), at panel display lasers, electroluminescence, biodevices, electro-optic modulator, infrared windows, optical sensors, phosphors, photoconductors etc, [40][41][42][43][44][45][46][47][48]. The ZnS nanostructure were prepared by chemical methods like hydrothermal [49], co-precipitation [50], polyol [51], nonaqueous chem{ical [52], microwavesolvothermal [53] and chemical bath deposition [54].…”

Non-covalent triazine framework decorated carbon nanotube were prepared by using cyanuric chloride (CC) and biphenyl (BP) and carbon nanotube (CNT) by Friedel-Crafts reaction. The prepared poly(cyanuric chloride-co-biphenyl)-carbon nanotube (Poly(CC-co-BP)-CNT) composite is used as a supporting materials for photocatalyst towards methylene blue (MB) dye degradation. Zinc sulphide (ZnS) and Zinc sulphide-Tin sulphide (ZnS-SnS) nanoparticles were doped on the surface of poly(cyanuric chloride-co-biphenyl)-carbon nanotube (Poly(CC-co-BP)-CNT) composite by using aqueous plant extract of Vanda Testacea as reducing agent. The ZnS/Poly(CC-co-BP)-CNT and ZnS-SnS/Poly(CC-co-BP)-CNT photocatalyst were analyzed using UV-DRS, PL, XRD, EDX and TEM methods. The durability of the prepared photocatalyst were tested using methylene blue dye under different UV light sources and sun light. The photocatalytic activity of ZnS-SnS/Poly(CC-co-BP)-CNT photocatalyst is found to be higher than ZnS/Poly(CC-co-BP)-CNT, unsupported ZnS and ZnS-SnS photocatalyst towards MB dye. This confirms that prepared ZnS-SnS/Poly(CC-co-BP)-CNT photocatalyst is effective for the removal of the methylene blue dye from waste water.

“…Research on a method of controlling the transmittance of sunlight through glass rather than installing an external shade has involved depositing metal oxides on glass surfaces using chemical vapor deposition, sputtering, or incorporating a substance exhibiting color/discoloration properties into the composition of glass [6]. However, glass produced by these methods does not include an active control function for sunlight.…”

Between 60% and 70% of the total energy load of a house or office occurs through the exteriors of the building, and in the case of offices, heat loss from windows and doors can approach 40%. A need for glass that can artificially control the transmittance of visible light has therefore emerged. Smart windows with suspended particle device (SPD) film can reduce energy consumption by responding to environmental conditions. To measure the effect of SPD windows on the energy requirements for cooling and heating in Korea, we installed a testbed with SPD windows. With TRNSYS18, the comparison between measurements and simulation has been made in order to validate the simulation model with respect to the modeling of an SPD window. Furthermore, the energy requirements of conventional and SPD-applied windows were compared and analyzed for a standard building that represented an actual office building. When weather for the city of Anseong and a two-speed heat pump were used to verify the simulation, the simulated electricity consumption error compared with the testbed was −1.0% for cooling and −0.9% for heating. The annual electricity consumption error was −0.9%. When TMY2 Seoul weather data were applied to the reference building, the decrease in electricity consumption for cooling in the SPD model compared with the non-SPD model was 29.1% and the increase for heating was 15.8%. Annual electricity consumption decreased by 4.1%.

Infrared (IR) antireflective and protective coating (ARPC) is crucial for the development of IR precision guidance and detection systems for practical applications, attracting significant attention from strong military powers worldwide. Extreme application environments require functional film to have high surface hardness, excellent stability, and good adhesion. Further, multispectral optical transmission demands extremely low absorption in the visible and far‐IR bands, adjustability of optical performance parameters, and optical antireflection in particular bands, and radar stealth requires a relatively low resistance. Herein, recent experimental progress on IR ARPC is reviewed and future opportunities are discussed. Based on the application environment and window substrate, various ARPC material systems, including diamond‐like C, Ge carbide, B phosphide, and oxides, have been developed. These systems are capable of fulfilling different application demands and demonstrate exciting application prospects. To promote the development of IR ARPC material technology, the basic characteristics, fabrication techniques, microscale structures, optical properties, mechanical properties, and development and applications of typical IR ARPC materials from a comprehensive and systematic perspective are presented.
