Article Abstract
A strategic roadmap for noncarbonized fuels is a global priority, and the reduction of carbon dioxide emissions is a key focus of the Paris Agreement to mitigate the effects of rising temperatures. In this context, hydrogen is a promising noncarbonized fuel, but the pace of its implementation will depend on the engineering advancements made at each step of its value chain. To accelerate its adoption, various applications of hydrogen across industries, transport, power, and building sectors have been identified, where it can be used as a feedstock, fuel, or energy carrier and storage. However, widespread usage of hydrogen will depend on its political, industrial, and social acceptance. It is essential to carefully assess the hydrogen value chain and compare it with existing solar technologies. The major challenge to widespread adoption of hydrogen is its cost as outlined in the roadmap for hydrogen. It needs to be produced at the levelized cost of hydrogen of less than $2 kg to be competitive with the established process of steam methane reforming. Therefore, this review provides a comprehensive analysis of each step of the hydrogen value chain, outlining both the current challenges and recent advances.

The breach of six planetary boundaries highlights the need for sustainable food production. Aerobic hydrogen-oxidising bacteria (HOBs) convert atmospheric CO and green hydrogen (H) into biomass via gas fermentation, a process already used for food-grade single-cell protein production. This approach enables a supply chain independent of agriculture, requiring minimal land and water, with potential for carbon-neutral production and carbon capture.

Inspired by "the composition of catechol and amine groups in the adhesive proteins" of marine mussel and "brick-and-mortar" structure of nacre, we use polydopamine (PDA) as "mortar", graphene oxides (GO) nanosheets as "brick", and Pd ions as interfacial reinforcer, to fabricate nacre-like Pd enhanced PDA functionalized GO membranes (Pd@PDA/GO) with vacuum filtration-assisted assembly method. Meanwhile, in situ reduced Pd nanoclusters by PDA chains were well constrained within the resultant Pd@PDA/GO artificial nacre composites. Good interfacial adhesion with dense packing of the GO nanosheets was further confirmed with sub-nano level microstructure characterization by positron annihilation lifetime spectroscopy.

The supramolecular organization of functional molecules at the mesoscopic level influences their material properties. Typically, planar π-conjugated (disc- or linear-shaped) molecules tend to undergo one-dimensional (1D) stacking, whereas two-dimensional (2D) organization from such building blocks is seldom observed in spite of their technological potential. Herein, we rationally achieve both 1D and 2D organizations from a single planar, π-conjugated molecular system competitive interactions.

With growing public attention to environmental issues and sustainable development, biodegradable bio-based plastics have attracted widespread interest. This study reveals the chemical-physical synergistic regulation mechanism of biodegradable PLA/PBAT blends through the synergistic modification of epoxidized natural rubber (ENR) and epoxy chain extender (ADR). Interfacial interaction analysis shows that PBAT tends to encapsulate ENR to form aggregates.

The interactions of three berberine mid-chain fatty acid salts ([BBR][C], n = 6, 7, 8) with lysozyme (Lyz) are investigated in detail using multi-spectroscopic and molecular docking techniques. Steady-state fluorescence and UV-visible absorption experiments suggest that the binding mechanism of [BBR][C] on Lyz is a static quenching with a binding ratio of 1:1. The compound [BBR][C] exhibits a moderate binding affinity toward Lyz.
