Abstract Lithium ion battery electrodes were manufactured using a new, completely dry powder painting process. The solvents used for conventional slurry-cast have been removed. Thermal activation time has greatly reduced due to the and resource demanding solvent evaporation process needed with electrode manufacturing being replaced by hot rolling It found that thermal induce mechanical bonding of thermoplastic polymer remaining active particles is only few seconds. Removing drying allows...
Conductive hydrogels have attracted much attention for their wide application in the field of flexible wearable sensors due to outstanding flexibility, conductivity and sensing properties. However, weak mechanical properties, lack frost resistance susceptibility microbial contamination traditional conductive greatly limit practical application.

Abstract Solar steam generation has emerged as a promising approach to address water scarcity issues globally. However, few challenges remain, including high cost, limited scalability, and salt accumulation, before this technique can be adopted by the general population. Here, an all‐in‐one photothermal fabric is reported such solar generator (SSG), consisting of commercial hydrophilic superfine denier polypropylene fiber water‐repellent expandable polyethylene foam, manufactured via...
The conflict between stiffness and toughness is a fundamental problem in engineering materials design. However, the systematic discovery of microstructured composites with optimal stiffness-toughness trade-offs has never been demonstrated, hindered by discrepancies simulation reality lack data-efficient exploration entire Pareto front. We introduce generalizable pipeline that integrates physical experiments, numerical simulations, artificial neural networks to address both challenges....
Currently, bioresorbable electronic devices are predominantly fabricated by complex and expensive vacuum-based integrated circuit (IC) processes. Here, a low-cost manufacturing approach for conductors on polymer substrates evaporation-condensation-mediated laser printing sintering of Zn nanoparticle is reported. Laser nanoparticles has been technically difficult due to the surface oxide nanoparticles. To circumvent oxide, novel discovered print sinter facilitated evaporation-condensation in...
Miniaturization of energy conversion and storage devices has attracted remarkable consideration in the application wearable electronics. Compared with film-based flexible electronics, fiber-based electronics (e.g., nanogenerators sensors made from electrospun nanofibers) are more appealing promising for wearables. However, there two bottlenecks, a low power output poor sensing capability, limiting piezoelectric nanofibers. Herein, we integrated zinc oxide nanorods (ZnO NRs) to less known...

Abstract The hole transporting layer (HTL) plays an important role in realizing efficient and stable perovskite solar cells (PSCs). In spite of intensive research efforts toward the development HTL materials, low‐cost, dopant‐free materials that lead to PSCs remain elusive.

This molecule easy synthesize inexpensive. It...
An elastic cloak is a coating material that can be applied to an arbitrary inclusion make it indistinguishable from the background medium. Cloaking against disturbances, in particular, has been demonstrated using several designs and gauges.
