Summary: Polymer brushes have attracted attention for their potential applications in various fields. However, the difficulties in precisely controlling their structure and composition have limited their properties. In this study, an effective strategy was developed to prepare structurally controllable atom transfer radical polymerization (ATRP) macroinitiators using polydienes and chlorine. By adjusting the reaction time, the amount of grafting allyl chloride groups could be controlled, leading to the synthesis of well-defined polystyrene brushes with worm-like and rod-like structures. The resulting polystyrene brushes exhibited low viscosity and high functionality, and were used to prepare a superhydrophobic nanomaterial with excellent antifouling performance.

Summary: A versatile nonequilibrium system of polymer brushes with spatiotemporally programmable properties and functions driven by chemical fuels is reported. The polymer brushes can self-regulate their swelling and deswelling process with tunable lifetimes by combining a responsive polymer with an autonomous pH regulator. Moreover, an autonomous fluorescence modulator and a self-regulated wettability switcher of polymer brushes have been implemented using patterned copolymer brushes with pH-responsive fluorescence moiety.

Summary: In this study, nanopatterned helical poly(benzyl-L-glutamate) (PBLG) brushes were fabricated using high-resolution lithography and surface-initiated vapor deposition polymerization (SI-VDP). The resulting nanospikes of polymer brushes with spacings of less than 100 nm were analyzed and compared with coil-type brushes. It was observed that rod-like polypeptide brushes are capable of self-segregation and can form well-defined nanostructures without external support.

Summary: Novel brush coatings were fabricated by surface-initiated atom transfer radical polymerization (SI-ATRP) using 2-(2-methoxyethoxy)ethyl methacrylate (OEGMA188) and acrylamide (AAm) grafted on glass surfaces, with different proportions. P(OEGMA188-co-AAm) brushes with a high AAm mole fraction (>44%) showed temperature-induced transformations in contact angle and thickness, indicating the formation of hydrophobic structures at Tc through hydrogen bonding between OEGMA188 and AAm. Additionally, P(OEGMA188-co-AAm) coatings exhibited a 'schizophrenic' behavior in wettability when immersed in pH buffer solutions.

Summary: Researchers utilize Fe doping in three-dimensional MoNi4 alloy crystal frameworks to enhance the efficiency and durability of a bifunctional catalyst for overall water splitting. Experimental analysis and simulations show that Fe doping improves conductivity, decreases free energy barriers, and weakens catalytic intermediate adsorption. The resulting MNF2.5 CF catalyst exhibits superior performance with an ultra-low overpotential of 187.18 mV and a low Tafel slope of 56.50 mV dec(-1) in 1 M KOH.

Summary: To effectively reduce the charge recombination of bulk CdS, this study designed ultrathin CdS-NiFeS 2D-2D heterojunctions with tight interfaces, in which NiFeS nanosheets derived from layered double hydroxides have tunable work functions and hydrogen evolution overpotentials. The optimized CdS-2% NiFe0.1S photocatalyst exhibits excellent hydrogen generation activity, reaching 626.7 mu mol/h (equivalent to 62.67 mmol/g/h), which is highly competitive among noble-metal-free CdS-based catalysts. The enhanced catalytic performance is attributed to the establishment of sufficient contact interfaces, the shortened charge transport distance, and efficient electron transfer from CdS to NiFeS, as well as the presence of the bimetallic NiFeS cocatalyst providing abundant active sites and lowering the reaction barrier for H2 generation. This research provides new insights for the development of 2D nanomaterials with outstanding photocatalytic performance.

Summary: By leveraging the advantages of shape retention and atomic reconstruction, boron-nitrogen codoped carbon nanosheets were efficiently manufactured through pyrolysis of metal-organic framework (MOF) precursors and B-dopants. The resulting nanosheets exhibited ultrahigh-surface heteroatomic doping rates, homogeneous distribution, and outstanding dispersion stability. As a lubricant additive, the hybrid oil containing these nanosheets displayed remarkable tribological performances, including lower friction coefficient, enhanced load-carrying ability, and reduced wear loss. Additionally, the B doping brought about dramatic antioxidation property and the formation of a robust protective tribofilm, which further improved the load-carrying and antiwear performances.

Summary: In this study, organic-inorganic hybrid sulfur-containing carbon nanospheres (SCNs) were prepared by chemical oxidation polymerization and subsequent carbonization. The as-prepared SCNs exhibited excellent oil-dispersing and tribological properties as lubricant nanoadditives, attributed to the good structural strength and organic phase derived from the precursor polythiophene. The friction mechanism of the SCNs was deduced, showing the ability of SCNs to form a strong protective film on the surface of friction pairs through physical deposition and tribochemical reaction.

Summary: This study presents a versatile surface-grafting strategy of molecular brushes to construct a stable ion-regulating interface for Zn metal batteries, which addresses the issues of dendrite growth and low cycling efficiency. The designed interface features dense sulfo-terminated nanochannels that serve as ion-redistributors, homogenizing the flux of Zn2+ across the interface and accelerating the deposition kinetics. The Zn anode with this interface demonstrates high Coulombic efficiency and ultralong cyclability, making it a promising candidate for high-rate and long-life Zn-metal batteries.
