Solar-Powered Sustainable Water Production: State-of-the-Art Technologies for Sunlight–Energy–Water Nexus

ACS Nano, Journal Year: 2021, Volume and Issue: 15(8), P. 12535 - 12566

Published: July 19, 2021

Alternative water resources (seawater, brackish water, atmospheric sewage, etc.) can be converted into clean freshwater via high-efficiency, energy-saving, and cost-effective methods to cope with the global crisis. Herein, we provide a comprehensive systematic overview of various solar-powered technologies for alternative utilization (i.e., "sunlight-energy-water nexus"), including solar-thermal interface desalination (STID), membrane (STMD), solar-driven electrochemical (SED), harvesting (ST-AWH). Three strategies have been proposed improving evaporation rate STID systems above theoretical limit designing all-weather or all-day operating by analyzing energy transfer condensation processes caused conversion. This review also introduces fundamental principles current research hotspots two other seawater (STMD SED) in detail. In addition, cover ST-AWH terms technology design, materials evolution, device assembly, etc. Finally, summarize content this discuss challenges future outlook different types technologies.

Highly compressible and anisotropic lamellar ceramic sponges with superior thermal insulation and acoustic absorption performances

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: July 24, 2020

Abstract Advanced ceramic sponge materials with temperature-invariant high compressibility are urgently needed as thermal insulators, energy absorbers, catalyst carriers, and temperature air filters. However, the application of is severely limited due to their complex preparation process. Here, we present a facile method for large-scale fabrication highly compressible, resistant SiO 2 -Al O 3 composite sponges by blow spinning subsequent calcination. We successfully produce anisotropic lamellar numerous stacked microfiber layers density low 10 mg cm −3 . The exhibit compression fatigue resistance, strain-independent zero Poisson’s ratio, robust fire resilience from −196 1000 °C, excellent insulation conductivity 0.034 W m −1 K In addition, structure also endows sound absorption properties, representing promising alternative existing acoustic materials.

Multifunctional Superelastic Cellulose Nanofibrils Aerogel by Dual Ice‐Templating Assembly

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 31(46)

Published: Aug. 16, 2021

Abstract A superelastic aerogel with fast shape recovery performance from large compressive strain is highly desired for numerous applications such as thermal insulation in clothing, high‐sensitive sensors, and oil contaminant removal. Fabrication of cellulose nanofibrils (CNF) aerogels challenging the CNF can assemble into non‐elastic sheet‐like cell walls.
