Proton Acceleration with Relativistic Electromagnetic Shock

open access: yesAdvanced Science, EarlyView.
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Advanced Atomic Layer Modulation Based Highly Homogeneous PtRu Precious Metals Alloy Thin Films

open access: yesAdvanced Science, EarlyView.
A unique idea of atomic layer modulation (ALM) that sequentially pulses DDAP and Ru(TMM)(CO)3, two precursors with one counter reactant O2 to produce ALM‐PtRu homogeneous PtRu bimetallic alloys at the nanoscale. It smartly adjusted precursor pulse time and temperature, ensuring stoichiometric and compositionally atomistic controlled highly ...

A Novel nor@DHB Matrix for Direct Microbial Analysis in Lung Cancer Tissues

open access: yesAdvanced Science, EarlyView.
Integrated matrix‐assisted laser desorption/ionization mass spectrometry workflow quantifies intratumoral microbes in lung cancer through lipopolysaccharide/lipid A extraction from biopsies. The novel ionic matrix called norharmane conjugated to 2,5‐dihydroxybenzoic acid enhances lipid A ionization, enabling direct detection of bacterial genera ...

One‐Step Syntheses of Face‐Centered Cubic OsxPt1‐x/C with Near‐Zero‐Overpotential Hydrogen Evolution from Electronic‐State Engineering

open access: yesAdvanced Science, EarlyView.
A one‐step in situ polyol method is proposed to realize steady‐state syntheses and phase control of immiscible OsxPt1−x/C catalysts with homogeneous atomic mixing states. The overpotential at 10 mA·cm−2 of face‐centered cubic (fcc)‐Os0.3Pt0.7/C in 0.5 m H2SO4 is only 1.0 mV as the top‐level HER catalyst.

Symmetry Breaking of Molecules Triggered by Chiral Inorganic Nanostructures Without Organic Components

open access: yesAdvanced Science, EarlyView.
Chiral nano‐inorganics, free of organic chiral ligands, provide a novel platform to direct symmetry breaking in molecular systems, through inorganic‐to‐organic chirality transfer via enantiospecific inorganic–organic interactions, circularly polarized light, and electron spin‐driven enantiopreferential reactions governed by chiral‐induced spin ...
