An all-wood hydrogel was synthesized via a simply Hofmeister effect without the use of any chemical cross-linking agent. The all-wood hydrogel shows a high tensile strength of 36.5 MPa, a strain up to ~ 438%, and good conductivity, and can accurately distinguish diverse large or subtle human movements. The all-wood hydrogel has good recyclable, biodegradable, and adjustable mechanical properties.

An ultralight, ultrathin iontronic triboelectric mechanoreceptor (ITM) is proposed with high specific outputs for multi-functional epidermal applications. Precise vital signals and physical activities monitoring of human bodies are noninvasively implemented by the ITM. Acoustic-to-electrical energy conversion is realized by the ITM, and biometric applications such as voices differentiation and the

The squid pen-derived aerogel with intrinsic electropositivity is prepared to electrostatically assemble carbon nano-onion with low escape energy. Under the guidance of PNM model, the interface polarization is reinforced from the aspect of porous skeleton, nanomaterials and multilayer construction. Benefiting from boosted Maxwell-Wagner-Sillars effect, the aerogel and film display remarkable electromagnetic

A multilayer architecture of layers with different functions alleviates bottlenecks in photoelectrochemical (PEC) hydrogen generation. Precise thickness control within a few nanometers defines each layer’s functionality. A Bi2S3/NiS/NiFeO/TiO2 photoanode had a photocurrent density of 33.3 mA cm−2 at 1.23 VRHE under AM 1.5 G illumination. Noble-metal-free seawater splitting was performed in an integrated

The slot-die-coated porous PbI2:CsI film assisted with nitrogen blowing can promote the rapid and complete transformation of perovskite film. The crystallinity and morphology of slot-die-coated perovskite film are significantly improved by controlling substrate temperature. Fully slot-die-coated perovskite solar cells achieve a power conversion efficiency (PCE) of 18.13%, and fully roll-to-roll printed
