Zinc and Manduca sexta hemocyte functions
Journal 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
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
, 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 ...

Advanced 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.

Angewandte 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.

Advanced 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
Angewandte 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

Divalent cations (Mg2+, Ca2+) protect bacterial outer membrane damage by polymyxin B
, 2013 Polymyxin B interacts with divalent cations by displacing cations from their binding sites in the lipopolysaccharide (LPS) molecules. It leads to the disorganization of the outer membrane component of the Gram negative bacteria, which releases LPS ...
