Photoelectrochemical (PEC) systems harness light absorption to initiate chemical reactions, while electrochemical reactions facilitate the conversion of reactants into desired products, ensuring more efficient and sustainable energy conversion in PECs. Central to optimizing the performance of PECs was the pivotal role played by interface engineering. This intricate process involves manipulating material interfaces at the atomic or nanoscale to enhance charge transfer, improve catalytic activity, and address limitations associated with bulk materials. The careful tuning of factors such as band gap, surface energy, crystallinity, defect characteristics, and structural attributes through interface engineering led to superior catalytic efficiency. Specifically, interface engineering significantly enhanced the efficiency of semiconductor-based PECs. Engineers strategically designed heterojunctions and manipulated catalyst surface properties to optimize the separation and migration of photogenerated charge carriers, minimizing recombination losses and improving performance overall. This review categorizes the discussion into four sections focusing on the interface engineering of PECs, providing valuable insights into recent research trends. Overall, the synergy between PECs and interface engineering holds tremendous promise for advancing renewable energy technologies and addressing environmental challenges by offering innovative solutions for sustainable energy conversion and storage.

Vagus nerve stimulation (VNS) is a promising therapy for neurological and inflammatory disorders across multiple organ systems. However, conventional rigid interfaces fail to accommodate dynamic mechanical environments, leading to mechanical mismatches, tissue irritation, and unstable long-term interfaces. Although soft neural interfaces address these limitations, maintaining mechanical durability and stable electrical performance remains challenging.

While bioprocesses using Escherichia coli, Corynebacterium glutamicum, various species of Bacillus, lactic acid bacteria, Clostridia, the yeasts Saccharomyces cerevisiae and Pichia pastoris, fungi such as Aspergillus niger, and Chinese hamster ovary cells are well established, the high level of microbial diversity has not yet been exploited industrially. However, the use of alternative organisms has the potential to significantly expand the process window of bioprocesses. These extensions include the use of alternative substrates (e.

Silicon carbide (SiC) membranes combine exceptional chemical, thermal, and mechanical stability but suffer from surface inertness that precludes functionalization. Conversely, MOFs offer unmatched molecular selectivity but are typically powders, severely limiting their practical use. To address this, we develop a generalizable route to fabricate ultrastable MOF@SiC membranes via sequential oxidation and acidification, creating abundant Si-OH sites on SiC surfaces that covalently bond with Zr-MOF crystals; the bonding mechanism between MOFs and substrates has been extensively studied.

Electrochemical CO reduction reaction (CORR) has emerged as a key negative-emission technology, yet its industrial adoption hinges on cathode catalysts that deliver high selectivity and production rates at low cost. Herein, we reported a facile hydrothermal route to synthesize different scales of ZnOHF ultrathin nanowires with hybridized ZnO/ZnOHF heterointerfaces, where the 40 nm variant (NW-ZnOHF) showed a high FE of 93 % and a of -17.2 mA/cm at -1.

During the long course of evolution, fish have developed complex skin structures to adapt to the dynamic aquatic environment. These skin features not only reflect optimal adaptation to the aquatic environment but also play a key role in effectively reducing fluid drag and improving swimming efficiency, to reveal the intrinsic connection between the complex skin structure of fish and drag reduction performance and to provide new design ideas for the drag reduction surface of underwater vehicles. Based on the different drag reduction characteristics of fish skin structures, this paper divides existing biomimetic drag reduction technologies into three categories: riblet drag reduction, flexible drag reduction, and composite drag reduction.
