However, these reactions are often constrained by bubble-related issues, which shield active sites, increase ohmic resistance, and limit the mass transfer of reactants and products. Bioinspired surface engineering, which modulates bubble behavior through the rational design of functional interfaces, provides an efficient strategy for resolving these aforementioned issues. This review systematically demonstrates how bioinspired surface engineering enhances the performance of gas-involving electrochemical reactions <i>via</i> optimized bubble management. First, we elucidate the fundamental principles of bubble dynamics and their direct impact on reaction efficiency. Subsequently, we explore diverse electrode design strategies derived from biological prototypes, including the development of superaerophilic, superaerophobic, wettability-heterogeneous, and geometry-gradient architectures.

We previously reported that daily consumption of unsalted, skin-roasted peanuts improved memory in older adults. Here, we investigated whether changes in brain insulin responsiveness may contribute to these effects. In a randomized, single-blind, controlled crossover study, 31 older adults (67 ± 4 years) consumed either 60 g day^-1 of unsalted, skin-roasted peanuts or followed a no-peanut control period for 16 weeks, separated by an 8-week washout. Brain insulin responsiveness was assessed as changes in cerebral blood flow (CBF) following intranasal insulin administration using arterial spin labeling magnetic resonance imaging (ASL-MRI). Intrahepatic lipid (IHL) content was quantified using abdominal MRI. Fasting blood samples were evaluated for markers of glucose homeostasis, lipid metabolism, and low-grade systemic inflammation. Whole-brain analysis identified one region in the right hemisphere showing reduced CBF responses to intranasal insulin after peanut intake compared with the control (mean difference: -5.4 ± 5.4 mL per 100 g tissue per min; cluster size = 552 mm³, <i>P</i> = 0.044). Harvard-Oxford atlas localization yielded the highest average probabilities for the lingual gyrus (20%), hippocampus (14%), parahippocampal gyrus (11%), thalamus (2%), and posterior cingulate gyrus (1%). Intrahepatic lipid content and circulating markers of glucose homeostasis, lipid metabolism, and low-grade systemic inflammation remained unchanged. These findings suggest that 16 weeks of unsalted, skin-roasted peanut consumption had a potentially beneficial effect on regional brain insulin responsiveness in memory-related brain regions in older adults.

However, their dense cell walls and fragile cellulose skeleton severely constrain the compressive recoverability and fatigue resistance. This constraint hinders their use as an elastic functional material toward high-performance, advanced applications. Herein, a synergistic strategy that combines multilevel cell-wall engineering with skeletal reinforcement is developed to fabricate superelastic and fatigue-resistant wood sponges. Specifically, by integrating the selective removal of non-skeletal components of the cell walls with a multi-hierarchical arched lamellar microstructural design and a robust hydrogen-covalent dual crosslinking network, wood sponges with expanded spacing and arched lamellar structure are obtained. Benefiting from this structure, the sponges achieve unprecedented elasticity (100% and 94.10% single-cycle height recovery at 90% and 95% compression strain, respectively) and superior fatigue resistance (96.99% height retention rate at 50% strain under 10 000 cycles). After conductivity modification, they exhibited multifunctional pressure-sensing capabilities with a broad detection range (1.57 MPa), high sensitivity (9.73 kPa^-1), and exceptional signal stability (12 000 cycles). These superior metrics guarantee broad applications in machine learning-assisted motion/gesture recognition and human-machine interaction.

The properties of microbially induced materials can be adjusted through structural regulation, with the introduction of a biomimetic structure being the preferred option. Herein, a bacteria-laden membrane is developed for structural regulation of biomimetic inorganic-organic multilayers on planar surfaces and in cylindrical pores. The urease-producing bacteria, <i>Sporosarcina pasteurii</i>, are encapsulated within a superimposed graphene oxide membrane to facilitate ureic hydrolysis. Subsequently, the diffusion of the bicarbonate constituents in a permeable microcompartment promotes the growth of biomimetic multilayers locally. While extracellular polymeric substances of bacteria contribute to the formation of multilayers with high strength and toughness, the bacteria themselves are responsible for this physicochemical process from a distance. The introduction of bacteria-laden membranes in a perforated polypropylene sheet fulfills the <i>in situ</i> formation of a biomimetic multilayer in each channel and complete sealing. Subsequently, the perforated polypropylene sheet integrated with biomimetic multilayers successfully impedes liquid permeation under hydraulic pressure.

In this study, we develop a <i>Pistia stratiotes</i> inspired armored Janus system consisting of a superhydrophilic carbon nanotube aerogel armored by superhydrophobic copper meshes on three surfaces for all-day continuous freshwater harvesting. This biomimetic armored Janus system enables a superior water harvesting performance, including an evaporation rate of 6.60 kg m^-2 h^-1 (system height 4 cm) under one-sun illumination and a fog collection rate of 5.53 g cm^-2 h^-1 (system height 0.5 cm) under high humidity conditions, completely surpassing previous all-weather water harvesting strategies. The substantial improvement in water harvesting efficiency intrinsically stems from the exquisite biomimetic design of the harvesting system, which effectively enhances the photothermal effect and salt resistance simultaneously. More importantly, although the two water harvesting strategies are independent in time and have different mechanisms, they synergistically enhance each other as manifested by the fact that fog droplets dissolve the salt deposition on the superhydrophilic aerogel caused by seawater evaporation, while evaporation removes the excessive accumulation of fog droplets on the superhydrophobic meshes. The designed system enables a stable continuous freshwater collection performance, approximately 33.49 L m^-2 each day under natural conditions for 15 days. The bionic design of the daylong freshwater harvesting system with excellent self-cleaning function provides an effective route for realizing continuous all-day freshwater production with robust anti-salt fouling performance, and holds great application potential in practical water harvesting scenarios.</p>","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":"10370-10381"},"PeriodicalIF":11.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148904527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
