Summary: Traditional sunscreens can penetrate the skin, raising safety concerns. To address this, a cellulose nanocrystal/polydopamine/poly(vinyl alcohol) (CNC/PDA/PVA) hydrogel was developed with biocompatibility, UV-shielding, and antioxidant properties. The hydrogel showed a compression strength of 5.0 MPa and remained stable after UV exposure. It demonstrated excellent biocompatibility, strong antioxidant capacity, and the ability to block 99.0% of UV light, protecting against UV-induced tissue injury. These findings highlight the potential of the CNC/PDA/PVA hydrogel as a next-generation UV absorber and antioxidant material.

Summary: In this study, a self-powered UV photodiode on a green substrate was successfully developed using a highly conductive AZO film and different electrode designs. The paper-based Schottky photodiodes operated without external power, with the Au-ZnO-AZO-Al structure showing improved response and faster speed compared to the Au-ZnO-Al structure. The enhancement in performance was attributed to the strong electric field in the ZnO-AZO n-n+ junction and the favorable ohmic contact between AZO and Al electrodes.

Summary: Passive radiative cooling materials offer all-day thermal comfort without energy consumption by reflecting solar radiation and emitting heat into the 3 K universe. However, conventional materials have non-recyclable complex structures and unsustainable polymers, leading to resource waste and environmental issues. This study presents a low-cost, scalable, and eco-friendly radiative cooling material called cooling paper, made from delignified cellulose fibers and nano-sized hydroxyapatite (HA). The resulting paper can be easily recycled and deconstructed to recover cellulose fibers and HA, which can be reused to prepare secondary products with comparable performance. The recyclable cooling paper shows a temperature drop of 6-8.8 degrees C under direct solar radiation and an average cooling energy saving of 29% in buildings across China, indicating its promising potential for sustainable energy-efficient buildings.

Summary: An efficient phenol-assisted depolymerisation (PAD) process was developed to selectively cleave methylene linkages in condensed lignins. Phenol served as a solvent to dissolve lignin and also scavenged methylene linkages to facilitate the depolymerisation. The PAD process achieved higher yields of lignin monomers and bisphenols compared to existing depolymerisation methods, and the residual polyphenols could be used in adhesive synthesis for plywood applications.
