Three-Dimensional Hierarchical Architectures Derived from Surface-Mounted Metal–Organic Framework Membranes for Enhanced Electrocatalysis

Three‐Dimensional Hierarchical Architectures Derived from Surface‐Mounted Metal–Organic Framework Membranes for Enhanced Electrocatalysis

Burnt to a crisp: Surface-mounted metal–organic framework (MOF) membranes were pyrolyzed to produce electrocatalytic nanomaterials with 3D nanoarchitectures and abundant catalytic sites. Cobalt contained in the MOF thin-film has a dual function; it facilitates growth of nitrogen-doped carbon nanotubes and promotes oxygen reduction, hydrogen evolution, and oxygen evolution reactions.

Membrane Fusion Mediated Intracellular Delivery of Lipid Bilayer Coated Mesoporous Silica Nanoparticles

Membrane Fusion Mediated Intracellular Delivery of Lipid Bilayer Coated Mesoporous Silica Nanoparticles

Mesoporous silica nanoparticles (MSNs) are delivered into cells via membrane fusion thereby omitting endocytosis pathways. Fusion is induced by a pair of complementary coiled-coil lipopeptides inserted into the membrane of cells and in the bilayer of lipid-coated MSNs. In this manner proteins can be efficiently delivered into the cytoplasm of cells.

Nanoparticles Embedded in Amphiphilic Membranes for Carbon Dioxide Separation and Dehumidification

Nanoparticles Embedded in Amphiphilic Membranes for Carbon Dioxide Separation and Dehumidification

Just add nanoparticles! A straightforward strategy to tailor CO2 permeability, selectivity, and water transport with the addition of zeolitic imidazolate frameworks into a rubbery amphiphilic polymer is proposed. The incorporation of zeolitic imidazolate framework (ZIF-71) nanoparticles increases the fractional free volume, permeability, and selectivity of poly(ethylene oxide) terephthalate and poly(butylene terephthalate) (PEOT/PBT) membranes.

Solvent-Templated Block Ionomers for Base- and Acid-Gas Separations: Effect of Humidity on Ammonia and Carbon Dioxide Permeation

Solvent‐Templated Block Ionomers for Base‐ and Acid‐Gas Separations: Effect of Humidity on Ammonia and Carbon Dioxide Permeation

A pentablock copolymer with charged moieties along the midblock displays promising separation performance for both basic and acidic gases under humidified conditions. The permeation of polar (NH3 and CO2) and non-polar (N2) penetrants through this amphiphilic copolymer has been measured by single- and mixed-gas methods to elucidate the influence of nanoscale morphology (controllably varied by solvent templating/annealing) and relative humidity.

Mechanical Stability Analysis via Neutral Mechanical Plane for High‐Performance Flexible Si Nanomembrane FDSOI Device

High-performance mechanically flexible Si nanomembrane (NM) fully depleted silicon-on-insulator (FDSOI) field-effect transistors are realized via neutral mechanical plane (NMP) optimization. This NMP-optimized Si NM flexible device, using both the analytical and numerical modeling, shows excellent mechanical and electrical stability even at a 1 mm bending radius. The strain at this point is less than 0.01% much smaller than the strain tolerance of 0.1%.

Twinned Growth of Metal-Free, Triazine-Based Photocatalyst Films as Mixed-Dimensional (2D/3D) van der Waals Heterostructures

Twinned Growth of Metal‐Free, Triazine‐Based Photocatalyst Films as Mixed‐Dimensional (2D/3D) van der Waals Heterostructures

Mixed-dimensional (2D/3D) layered, van der Waals heterostructures based on triazine linkers are produced in a facile, one-pot, “wet” chemistry process. Macroscopic films of the material grow via a twinned mechanism—first the 2D crystalline phase then the 3D polymer—on a copper support that acts both as a catalyst and template and form an efficient type I heterojunction.

DMSO Chemically Alters Cell Membranes to Slow Exocytosis and Increase the Fraction of Partial Transmitter Released

DMSO Chemically Alters Cell Membranes to Slow Exocytosis and Increase the Fraction of Partial Transmitter Released

Permitting neurotransmitter passage: Dimethyl sulfoxide (DMSO) is commonly used in biological studies and as a vehicle for drug delivery. This study shows that DMSO chemically affects the permeability of cell membranes and possibly alters proteins involved in opening or closing pores during vesicle fusion, leading to a larger fraction of catecholamine being released from each vesicle.

Biocatalytic Stimuli-Responsive Asymmetric Triblock Terpolymer Membranes for Localized Permeability Gating

Biocatalytic Stimuli‐Responsive Asymmetric Triblock Terpolymer Membranes for Localized Permeability Gating

Dynamically responsive nanoporous membranes with high substrate specificity and localized gating response are fabricated by integration of self-assembly and nonsolvent induced phase separation process from poly(isoprene-b-styrene-b-4-vinylpyridine) with pore functionalization by an enzyme (phosphotriesterase). This offers intriguing opportunities for molecularly engineered biomimetic materials tailored to respond to a complex range of external parameters, providing sensing, protection, and remediation capabilities.
