Porous coordination polymer-derived CeO2-SnO2@S-C heterojunction nanocomposite for supercapacitor and oxygen evolution reaction

Porous coordination polymers (PCPs) and derived nanocomposites have attained substantial attention for electrochemical energy conversion and storage technologies owing to their tunable frameworks and favorable electrochemical characteristics. Here, we present a route for preparin...

Threshold-Safe Shock Absorption in a Compartmental Voter-Flow Model: A Conservative Impulse-Control Benchmark

Abstract We formulate an analytical, non-calibrated benchmark for threshold-safe staging of a fixed external load in a reduced compartmental voter-flow model. The state $$A(t)$$ A ( t ) is an effective stock of stress, backlog, or alienation, and $$S(t)$$ S ( t ) is a local mobil...

A self-assembled peptide forms α-helical nanopores for ultrasensitive biomarker profiling

α-Helical nanopores are attractive molecular sensors, yet their rational design and assembly remain challenging. Here we show that the single peptide pPorA, derived from porin PorACj, self-assembles into flexible α-helical nanopores, inserts in lipid membranes and exists in disti...

Probing Voltage Dependence Interaction of Cationic Peptides with Bacterial Porins at A Single-Molecule Level

Abstract This study examined how cationic α‑helical antimicrobial peptides such as protamine exchange between the aqueous phase and the transmembrane β‑barrel porin OmpF ( E. coli ) at the single‑molecule level. High‑resolution conductance recordings in planar lipid bilayers reve...

Predict-then-optimise interchange control for rail logistics with combined passenger-freight chains

Interchange decisions at rail transfer stations directly affect end-to-end service reliability and cost-to-serve; yet, existing delay-management approaches either forecast delays without prescribing actions or optimise dispatch with coarse delay representations. We propose a pred...
