pH‐dependent peptide biomaterials hold tremendous potential for cell delivery and tissue engineering. However, identification of responsive self‐assembling sequences with specified secondary structure remains a challenge. In this work, An experimental procedure based on the one‐bead one‐compound (OBOC) combinatorial library is developed to rapidly screen self‐assembling β‐sheet peptides at neutral...
Solar‐driven production of hydrogen peroxide (H2O2), as an important industrial chemical oxidant with an extensive range of applications, from oxygen reduction is a sustainable alternative to mainstream anthraquinone oxidation and direct hydrogenation of dioxygen methods. The efficiency of solar to hydrogen peroxide over semiconductor‐based photocatalysts is still largely limited by the narrow light...
Spin selectivity physically depends on either magnetic materials with strong internal magnetic fields or symmetry‐breaking materials with large spin–orbit coupling (SOC). However, the spin selectivity of symmetry‐breaking magnetic materials is not understood. Herein, the spin selectivity of iron oxides with different magnetisms arising from varying spin alignment is investigated. Chiral mesostructured...
Ionic conductive hydrogel electrolyte is considered to be an ideal electrolyte candidate for flexible supercapacitor due to its flexibility and high conductivity. However, due to the lack of effective recycling methods, a large number of ineffective flexible hydrogel supercapacitors caused by some irreversible damages and dryness of hydrogel electrolyte are abandoned, which would induce heavy economic...
A substrate mimicking the surface topography and temperature sensitivity of skin goosebumps is fabricated. Close‐packed arrays of thermoresponsive microgel particles undergo topographical changes in response to temperature changes between 25 and 37 °C, resembling the goosebump structure that human skin develops in response to temperature changes or other circumstances. Specifically, positively charged...
Skin goosebumps form in response to specific internal/external stimuli in the environment. In article number 1902376, Bin Li and co‐workers develop goosebumps‐inspired microgel patterns based on self‐assembled thermoresponsive microgels on polymer brushes modified substrate through electrostatic adsorption. The temperature responsiveness of the microgel monolayer assemblies allows reversible changes...
Rechargeable magnesium batteries (RMBs) that use pure Mg or Mg alloy as anode and materials allowing Mg ions to insert/extract as cathode have many advantages such as high energy density, environmental friendliness, low cost, and safety of handling. RMBs are regarded as a promising candidate for portable power sources and heavy load energy devices. However, there are still some technological issues...
In this work, the progress in the design of nonsiliceous mesoporous materials (nonSiMPMs) over the last five years from the perspectives of the chemical composition, morphology, loading, and surface modification is summarized. Carbon, metal, and metal oxide are in focus, which are the most promising compositions. Then, representative applications of nonSiMPMs are demonstrated in energy conversion...
A graphene oxide conductive hydrogel is reported that simultaneously possesses high toughness, self‐healability, and self‐adhesiveness. Inspired by the adhesion behaviors of mussels, our conductive hydrogel shows self‐adhesiveness on various surfaces and soft tissues. The hydrogel can be used as self‐adhesive bioelectronics, such as electrical stimulators to regulate cell activity and implantable...
