HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Miscibility of poly(ether ether ketone)/poly(ether diphenyl ether ketone) blends
Poly(ether ether ketone) and poly(ether diphenyl ether ketone) homopolymers are prepared by nucleophilic substitution routes. Miscibility of PEEK/PEDEK blends has been studied by wide-angle X-ray diffraction (WAXD) and differential scanning calorimetry (d.s.c.).

This study highlights the impact of transition‐metal (TM) ions (Ni2⁺, Mn2⁺, Co2⁺) on the performance of lithium‐metal anode in localized high‐concentration electrolytes. Mn2⁺ and Co2⁺ destabilize SEI and CEI layers, causing capacity fade and overpotential, while Ni2⁺ shows minimal effects. These findings underscore the need for electrolyte optimization

Na2S Presodiation Enables Long Cycling Anode‐Free Sodium Batteries via Rapid Spontaneous Reactions
Na2S with high sodium content is utilized as a sodium replenishment material for AFSBs. The spontaneous reaction between polysulfides and Na3−xV2(PO4)3, complete conversion from Na2S to sulfur is achieved under low voltage and catalyst‐free conditions. With the assistance of the additionally supplied sodium ions, the Na2S@NVP||Zn AFSBs retain 70.8% of ...

Fully Bio‐Based Epoxy Resins from Liquefied Wood for Chemically Recyclable Wood Coatings
A bio‐based and chemically recyclable epoxy resin derived from liquefied wood and its use in wood coatings is presented. The resin exhibits mechanical, thermal, and water‐resistant properties comparable to commercial coatings and can be chemically recycled and reused. This approach provides fast access to glossy and fully biobased durable wood coatings
