A facile one-step fabrication of coaxial fiber-based smart patterns for E-textile through 3D printing equipped with a coaxial spinneret is reported. Versatile smart textiles for different purposes can be fabricated by selecting different materials in construction of the coaxial layers. Examples such as silk energy-harvesting textile and energy-storage textile with superior performance are demonstrated.

Pseudocapacitance plays an important role in high-power lithium-ion batteries (LIBs). However, it is still lack of effective methods to tailor the pseudocapacitance contribution in electrode materials for LIBs. Herein, pseudocapacitance tuned by the strength of C-S bonding has been rendered in WS nanorods anchored on the N,S codoped three-dimensional graphene hybrid (WS@N,S-3DG) for the first time. The pseudocapacitive contributions in the charge storage can be enhanced effectively with the increased strength of C-S bonding. As expected, the enhanced extrinsic pseudocapacitance makes WS@N,S-3DG a fascinating electrode material for high-power LIBs, with a high reversible capacity of 509 mA h g over 500 cycles at a current density as high as 2 A g. These encouraging results of pseudocapacitance tailored by chemical bonding provide new opportunities for designing advanced electrode materials.

A self-floating photothermal membrane with simultaneous mechanical stability and antibacterial activity is facilely prepared for efficient solar-driven interfacial water evaporation.

Porous MoS2 nanoflower-containing hydrogels are proposed as enhanced light trapping and antibacterial photothermal hotspots and are facilely deposited on a hydrophilic MCE substrate for highly efficient solar-driven interfacial water evaporation.

Using first-principle atomistic simulations, we focused on the electronic structures of small gas molecules (CO, HO, NH, NO, and NO) adsorbed on the S-vacancy SnS monolayer. The results show that HO and CO molecules were physisorbed on the S-vacancy SnS monolayer, whereas NH, NO, and NO molecules were chemisorbed on the S-vacancy SnS monolayer via strong covalent bonds. Moreover, our calculations show that HO and NH act as charge donors, whereas CO, NO, and NO gas molecules act as acceptors. Different adsorption behaviors of common gas molecules on the S-vacancy SnS monolayer provide a feasible way to exploit chemical gas sensors and electrical devices. In particular, our results also show that under applied biaxial strains, the adsorption energy and charge transfer of gas molecules on the S-vacancy SnS monolayer dramatically changed, which indicates that external factors on the S-vacancy SnS monolayer are highly preferred.
