Farm to cable: life cycle assessment of carbon electrocatalysts derived from coffee waste
AbstractTo realize the full potential of biomass waste-derived electrodes, their synthesis must be fully reproducible and their environmental life cycle impact must be assessed quantitatively. We now show how a systematic comparison of coffee waste as a source for direct hydrazine fuel cell anodes can inform the first full life cycle assessment (LCA) of this application. The

Surface growth of mixed metal oxide thin rafts and their impact on methane dry reforming
AbstractSynergistic interactions between the supported thin oxide layer and the underlying metal oxide support led to the development of novel and exciting material properties. In this work, we present a new and general approach for the surface growth of MgAl layered double hydroxides (LDH) on ZrO₂, Al₂O₃, and TiO₂ support materials. We examine the synergistic interactions

Biomass or bio-mess: tackling reproducibility in biomass-derived carbon electrocatalysts
AbstractThe pyrolysis of biomass is a promising route toward carbon electrodes, but its adoption in electrocatalysis is mostly limited to the oxygen reduction reaction. To prepare precise active sites for other electrocatalytic reactions in the oxygen, nitrogen, and carbon cycles, the complexity of both the biomass precursor and the pyrolysis process must be reigned in. We now

Intracellular delivery of full-length antibodies via organ targeted lipid nanoparticles
AbstractAntibodies are proteins prized for their ability to bind to extracellular antigens with exceptionally high affinities and specificities. These features have motivated researchers to utilize antibody-antigen binding to inhibit intracellular disease targets in the proteome, yet delivery of antibodies into the cytosol of cells has long been a considerable challenge. Here

Heterobinuclear Molecular Precursors Direct the Formation of Supported Subnanometer Cu–M Clusters with Tunable Catalytic Behavior
AbstractSubnanometer bimetallic clusters hold great promise for catalytic applications due to their unique electronic properties and high surface-to-volume ratios. However, precise control over their composition and size remains a major challenge, particularly for immiscible metal pairs. Here, we report a surface-anchored molecular approach for synthesizing ∼0.7–0.8 nm Cu–M (M

Thickness Dependence and Fundamental Limitations for Ion Permeation in Nanoscale Films
AbstractNanoscale films play a central role in biology and osmotic separations. Their water/salt selectivity is often regarded as intrinsic property, favoring thinner membranes for faster permeation. Here we highlight and quantify a fundamental limitation arising from the dependence of ion self-energy on film thickness, governed by its ratio to Bjerrum length. The resulting

A 2.7-μm-thick robust, permeable, and antifreezing hydrogel electrode for long-term ambulatory health monitoring
AbstractAdaptable hydrogel bioelectronics that sustain long-term, uninterrupted operation are critical for early disease diagnosis and personalized health care. However, conventional hydrogel electrodes suffer from mechanical fragility, rapid dehydration, freezing, and poor comfort because of thickness-induced interfacial gaps. We report a 2.7-micrometer-thick robust, permeable

AI-Validated Brain Targeted mRNA Lipid Nanoparticles with Neuronal Tropism
AbstractTargeting therapeutic nanoparticles to the brain poses a challenge due to the restrictive nature of the blood–brain barrier (BBB). Here we report the development of mRNA-loaded lipid nanoparticles (LNPs) functionalized with BBB-interacting small molecules, thereby enhancing brain delivery and gene expression. Screening brain-targeted mRNA-LNPs in central nervous system

Stimuli-Responsive Colloidal Gate for Active Modulation of Fluid Flow in Packed Beds
AbstractWe present pH-responsive colloidal paste based on brushes of poly(acrylic acid) (PAA) grafted on silica microparticles (∼4 μm) that actively modulates bulk fluid flow in packed bed columns of the colloid paste. pH-dependent charge and conformational changes of the PAA brushes in aqueous 10 mM NaNO3 solutions (pH 2–10) give an 8-fold change in flow rate (0.04–0.32 mL/min)

Does the presence of CO2 affect the alkaline stability of anion-exchange membranes?
AbstractAnion-exchange membranes (AEMs) enable electrochemical energy devices to operate in alkaline environments, allowing the use of earth-abundant, platinum group metal-free catalysts. This makes them highly attractive for applications such as AEM fuel cells (AEMFCs), water electrolyzers (AEMWEs), and oxygen separators (AEMOSs). However, two key challenges still hinder their
