Anion‐Cation Synergistic Passivation for High‐Performance FA‐Cs Halide Perovskite Photodetectors

open access: yesAdvanced Electronic Materials, EarlyView.
An anion‐cation synergistic passivation strategy is developed to improve perovskite photodetectors. Surface‐localized DMePDA2+ cations and bulk‐diffused Cl− anions simultaneously reduce defects, enhancing charge transport and suppressing recombination.

Multiscale Design of Anion Exchange Membrane‐Based Seawater Electrolysis for Sustainable Hydrogen Production

open access: yesAdvanced Energy Materials, EarlyView.
Direct seawater electrolysis using anion exchange membranes is emerging as a promising route for sustainable hydrogen production. This review summarizes multiscale design strategies from seawater chemistry and OER–ClER selectivity to catalysts, membranes, MEAs, cells, stacks, and system integration, providing a roadmap toward selective, durable, and ...

Zinc and Manduca sexta hemocyte functions

open access: yesJournal of Insect Science, 2002
Two metalloproteases have recently been linked to the immune response in Lepidoptera. In addition, zinc is highly important in many mammalian immune-related functions.

Assembly of histidine-rich protein materials controlled through divalent cations

open access: yes
Nanostructured protein materials show exciting biomedical applications, since both structure and function can be genetically programmed. In particular, self-assembling histidine-rich proteins benefit from functional plasticity that allows the generation ...

Ion chromatographic separation of hydrogen ion and other common mono- and divalent cations

open access: yes, 2004
We introduced an approach to the ion chromatographic determination of common mono- and divalent cations including hydrogen ion and demonstrated the ability of a C30 column dynamically coated first with dodecylsulfate and then with 18-crown-6 ether to ...

Chloride‐Mediated Activation of Aluminum‐Alloyed Liquid Metal Anodes for Stretchable Asymmetric Energy Storage

open access: yesAdvanced Energy Materials, EarlyView.
A gallium‐centered cell pairs an aluminum‐alloyed GaIn anode with a GaOOH cathode in a chloride‐rich water‐in‐ionic‐liquid electrolyte. Chlorogallate ions dissolve the native oxide that normally seals the liquid metal, and preferentially reduce indium seeds to oxide‐free clusters on which gallium plates and strips reversibly.

Extending Small‐Molecule Aptamer Discovery Principles to Protein Targets: Selection and Characterization of Green Fluorescent Protein Aptamers

open access: yesAngewandte Chemie, EarlyView.
Protein‐binding aptamers remain poorly understood compared to their small‐molecule counterparts. Using green fluorescent protein (GFP) variants as a tractable model system, we show how subtle changes in protein surface composition and divalent metal ions reshape aptamer selection, specificity, and binding.

Self‐Driving Laboratory Optimizes the Lower Critical Solution Temperature of Thermoresponsive Polymers

open access: yesAdvanced Intelligent Discovery, EarlyView.
A low‐cost, self‐driving laboratory is developed to democratize autonomous materials discovery. Using this "frugal twin" hardware architecture with Bayesian optimization, the platform rapidly converges to target lower critical solution temperature (LCST) values while self‐correcting from off‐target experiments, demonstrating an accessible route to data‐

Switching ATP‐Forming Phosphoryl‐Transfer Chemistry With a Restricted Set of Amino Acids

open access: yesAngewandte Chemie, EarlyView.
Constraints on amino acid composition relevant to prebiotic chemistry reshape enzyme chemistry by replacing the canonical mechanism within a conserved protein fold with a distinct ATP‐forming reaction, ADP disproportionation. Such constraints generate alternative catalytic solutions not observed in modern enzymes and point to chemically plausible early
