Abstract In this work, we rationally designed and fabricated an S-scheme GaOOH@PDA heterojunction under the guidance of density functional theory (DFT) calculations. Compared with pristine GaOOH, the as-fabricated GaOOH@PDA heterojunction exhibited nearly doubled photocurrent density and lower charge-transfer resistance, which indicated highly efficient separation and migration of photogenerated …

Abstract Pickering interfacial catalysis in Pickering emulsions offers a promising platform for heterogeneous catalytic reactions. In the present work, immobilized matrixes with tunable hydrophobicity were fabricated by grafting hydrophilic silica particles with different amounts of octadecyltrichlorosilane (ODTs). By screening the activity of corresponding immobilized lipases, hyperperformance, …

Abstract Polymer adsorption at solid/liquid interfaces plays a crucial role in many applications, yet the molecular pathway of adsorption remains difficult to resolve experimentally. Here, we investigated the adsorption of poly(methyl methacrylate) (PMMA) and polystyrene (PS) from solution onto silica using in situ, real-time sum frequency generation vibrational spectroscopy. PMMA adsorption proc…

Abstract The drying behavior of poly(N-isopropylacrylamide)-grafted silica (SiO2–PNIPAM) particle suspensions in binary ethanol/water (EtOH/H2O) mixtures was investigated as a function of solvent composition and temperature. In pure H2O, the particles undergo a hydrophilic-to-hydrophobic transition near the lower critical solution temperature (LCST, ∼33 °C), producing coffee-ring patterns at 25 °…

Abstract To address the issues of poor interfacial stability, limited functionality, and low wearing comfort in flexible electronic skins, a breathable piezoelectric sensing film with dual pressure–temperature sensing capability was developed through electrospinning, interfacial modification, and magnetron sputtering. Polydopamine (PDA) was used to strengthen the interfacial bonding between inorg…

Abstract Responsive dynamic afterglow carbon dot (CD) materials, which can continuously emit light of dynamically varying color after excitation cessation, promise broad applications in advanced information encryption and related fields. However, as most reported CD-based afterglow systems still exhibit single-variable-responsive color evolution, their applicability to information encryption and …

Abstract The lack of robust and tunable redox reporters continues to hinder the development of high-performance electrochemical biosensors. In this work, we present a combined computational and experimental investigation of a family of water-compatible Os(II) complexes as pH-insensitive alternatives to the gold-standard methylene blue (MB). We systematically engineered, synthesized, and character…

Abstract Nickel nanofilms were prepared at an ethaline/toluene interface, which is a water-free deep eutectic solvent (DES)/oil (O) interface, where the absence of water enables a unique environment for interfacial redox chemistry. When NiCl42– in ethaline was contacted with decamethylcobaltocene (DMCc) in toluene at the liquid/liquid interface, nickel nanoparticles nucleated and subsequently ass…

Abstract Unlike traditional well pumping from bulk reservoirs, trees can extract and elevate water spontaneously from moist soil. Here, we demonstrate transpiration-driven underground water harvesting by burying the bottom of a synthetic tree in water-saturated soil while encasing the nanoporous leaf within a condensing still. Evaporation from the leaf facilitates the continual transport of water…

Abstract In situ biological systems are continuously exposed to physical (temperature) and chemical (pH) cues, which provide critical inputs for biosensing. However, pathological microenvironments exhibit dynamically intertwined variations in these parameters, necessitating a sensing platform capable of real-time signal transduction and decoupling. Conventional rigid sensors suffer from mechanica…

Abstract In this work, we introduce a dynamic NMR relaxometry approach to monitor gel drying not as a function of time, but through the evolution of the transverse relaxation time (T2) as a function of gel saturation. This formulation enables us to track, with high temporal resolution and in a noninvasive manner, how homogeneity evolves during the drying of deformable colloidal systems. The origi…

Abstract Antimicrobial peptides (AMPs) disrupt bacterial membranes through mechanisms that differ fundamentally from conventional antibiotics, yet the interfacial transition from peptide adsorption to membrane destabilization remains difficult to resolve experimentally.
