Cellulose‐based Interfacial Solar Evaporators: Structural Regulation and Performance Manipulation

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(36)

Published: May 15, 2023

Abstract The shortage of freshwater resources has become a major obstacle threatening human development, and directly utilizing solar energy by evaporators is emerging as promising method to produce from the seawater. Compared many synthetic polymer‐based evaporators, cellulose‐based are expected offer more interesting features benefiting renewable feature abundant reserves cellulose‐contained naturally occurring materials. First, according different fabrication methods, can be divided into two types, i.e., top‐down utilization (wood‐based) bottom‐up assembled (cellulose composite‐based), respectively. schemes also bring their own unique advantages, such bimodal porous structure wood‐based artificial interconnection microporous network cellulose composite‐based evaporators. Subsequently, this review further summarizes most recent advances highlights those focusing on structural regulation strategies (e.g., drilled channel array, asymmetric wettability structure, delignification, 2D waterway, etc.) evaporation performance improvements salt resistance, high rate, etc.). Finally, challenges in field potential solutions discussed, which anticipated provide new opportunities toward future development other kinds biomass‐based

ZnO is a semiconductor material that has important physical and chemical properties, which are frequently significantly enhanced by the addition of impurities, such as doping. A study structural properties pristine functionalized (i.e., doped with Antimony Tungsten) nanoparticles been conducted for photocatalyst-based degradation methylene blue (MB) dye under both Ultraviolet (UV) solar light. Authors have used 1% concentration dopant doping purposes. The synthesized materials were characterized analysis, functional group identification, spectroscopic measurements, morphological examination using X-ray diffraction (XRD), Fourier transform-infrared (FTIR), UV-Vis spectroscopy (UV-Vis), Field emission scanning electron microscope (FESEM) techniques. XRD analysis confirmed synthesized-doped retained wurtzite hexagonal structure purity 99%. Transmission (TEM) data reveals average size pure ZnO-NPs was found to be 7 nm; after increased 18 nm 9.55 nm, respectively, ZnO-W ZnO-Sb.

UV absorption enhanced polydopamine coating

Materials Horizons, Journal Year: 2024, Volume and Issue: 11(10), P. 2438 - 2448

Published: Jan. 1, 2024

Mussel-inspired polydopamine (PDA) coatings have gained significant attention in various fields, including biomedicine, energy, detection, and UV protection, owing to their versatile promising properties. Among these properties, shielding stands out as a key feature of PDA coatings. Nevertheless, the current methods for tuning UV-shielding properties are quite limited, only rely on thickness adjustment, which might involve additional issues like color visible light transmittance coating layer. In this study, we propose facile modular approach enhance absorption by incorporating thiol-heterocycle (TH) derivatives. Both pre- post-modification strategies can effectively impede formation conjugated structures within PDA, leading enhanced layers. More importantly, improve while reducing absorption. Furthermore, method enabled efficient regulation altering ring type (benzene or pyridine ring) substituent (methoxyl group hydrogen atom). These with demonstrate great promise applications antibacterial activity, wound healing dye degradation.
