Solar‐Driven Desalination
In article number 2307005, Liming Wang, Xiaohong Qin, and co‐workers present an electrospun nanofiber‐based all‐in‐one vertically interfacial solar evaporator, endowed with a high steam generation rate, steady omnidirectional evaporation, and enduring ultrahigh‐salinity brine desalination. Salt ions can be effectively exchanged with the bulk water due to strong action of...
Solar‐driven interfacial desalination is widely considered to be a promising technology to address the global water crisis. This study proposes a novel electrospun nanofiber‐based all‐in‐one vertically interfacial solar evaporator endowed with a high steam generation rate, steady omnidirectional evaporation, and enduring ultrahigh‐salinity brine desalination. In particular, the electrospun nanofiber...
In this work, high‐performance epoxy resin (EP) composites with simultaneous excellent thermal conductivity (TC) and outstanding electromagnetic shielding properties are fabricated through the structural synergy of 1D carbon nanotubes and 2D silver‐modified boron nitride nanoplates (CNT/AgBNs) to erect microscopic 3D networks on long‐range carbon fiber (CF) felt skeletons. The line‐plane combination...
Room‐temperature phase change materials (RTPCMs) exhibit promise to address challenges in thermal energy storage and release, greatly aiding in numerous domains of human existence and productivity. The conventional RTPCMs undergo inevitable volume expansion, structural collapse, and diffusion of active ingredients while maintaining desirable phase change enthalpy and ideal phase change temperature...
Extremely low temperature has posed huge burden on the public safety concerns and global economics, thereby calling for high‐performance warmth retention materials to resist harsh environment. However, most present fibrous warmth retention materials are limited by their large fiber diameter and simple stacking structure, leading to heavy weight, weak mechanical property, and limited thermal insulation...
Bi2O3/rare earth oxide biphasic absorbers are attractive for high‐efficiency X‐ray shielding due to the complementary X‐ray absorption effects. However, its application is severely hindered by poor interphasic contact. Here, a new Janus interface engineering strategy is reported for the construction of continuous and flexible Bi2O3/Gd2O3 crystal nanofibrous membranes (FJNMs) with micro/nano dual self‐strengthening...
Waterproof and breathable membranes that prevent liquid water penetration, while allowing air and moisture transmission, have attracted significant attention for various applications. Electrospun nanofiber materials with adjustable pore structures, easily tunable wettability, and good pore connectivity, have shown significant potential for constructing waterproof and breathable membranes. Herein,...
Gating molecular separation using artificial sub‐nanoporous molecular sieves is highly desirable in large‐scale chemical and energy processing, such as gas separation, hydrogen recovery, carbon dioxide capture, seawater desalination, etc. However, it has remained an insurmountable challenge to create such materials. Herein, a binary meso‐reconstruction strategy to develop biomimetic sub‐nanoporous...
Oxide perovskite ceramics are cornerstone materials of electronic devices, but they easily break under bending. Such brittle failure phenomenon limits their applications in emerging flexible electronics. Here, the authors propose a scalable approach of sol–gel electrospinning to synthesize flexible perovskite Li0.35La0.55TiO3 (LLTO) nanofibers (NFs) by reducing grain sizes and pore defects in the...
Airborne particulate matter (PM) pollutants, especially with nanoscale size, have caused serious public health issues. The global demand for high‐performance and recyclable face masks is increasing dramatically, especially during the COVID‐19 pandemic. However, present masks suffer from low‐efficiency interception of PM0.3/pathogen, limited air permeability, and incapacity to reuse and recycle. Here,...
Organophosphorus‐based chemical warfare agents (CWAs) are highly poisonous, and recent attacks using nerve agents have stimulated researchers to develop breakthrough materials for their fast degradation. Zr‐based materials have been identified as the most effective catalysts for breaking down CWAs, but in their powdered form, their practical application in personal protective equipment is limited...
The novel coronavirus SARS‐CoV‐2 has prompted a worldwide pandemic and poses a great threat to public safety and global economies. Most present personal protective equipment (PPE) used to intercept pathogenic microorganisms is deficient in biocidal properties. Herein, we present green nanofibers with effective antibacterial and antiviral activities that can provide sustainable bioprotection by continuously...
Directional water transport is a predominant part of functional textiles used for continuous sweat release in daily life.

The filtration performance and light transmittance of nanofiber air filters are restricted by their thick fiber diameter, large pore size, and substrate dependence, which can be solved by constructing substrate‐free fibrous membranes with true nanoscale diameters and ultrathin thicknesses, however, it has proven to be extremely challenging. Herein, a roust approach is presented to create free‐standing...

A hydrophobic to super‐hydrophilic gradient structure provides...
The lethal danger of particulate matter (PM) pollution on health leads to the development of challenging individual protection materials that should ideally exhibit a high PM2.5 purification efficiency, low air resistance, an important moisture‐vapor transmission rate (MVTR), and an easy‐to‐clean property.
