Packaging Metal Atomic Clusters for Universal and Robust Protection through Cluster Beam Process

Advanced Science, EarlyView.
Gas‐phase‐aggregated metal clusters are packaged and well‐protected in poly(methyl methacrylate) (PMMA) through controlled beam implantation. The packaged precise clusters show robust protection against oxidation and agglomeration. This protection also demonstrates universality, as it successfully protects metal clusters composed of various elements ...

Proton Acceleration with Relativistic Electromagnetic Shock

Advanced 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.

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

Advanced 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 ...

Microwave‐Driven Dielectric‐Magnetic Regulation of Graphite@α‐MnO2 Toward Enhanced Electromagnetic Wave Absorption

Advanced Science, EarlyView.
This study presents a microwave‐activated composite integrating expanded graphite with α‐MnO2 nanowires, engineered to synergistically optimize dielectric and magnetic properties. The innovative microwave‐driven process enables rapid structural transformation, yielding ultrathin, scalable electromagnetic wave‐absorbing films.

Unconventional Topological Weyl Dipole Phonon

Advanced Science, EarlyView.
A new higher‐order topological phonon state is proposed, which integrates an unconventional Weyl dipole phonon (a charge‐3 Weyl point and three charge‐1 Weyl points) with higher‐order topology. Moreover, the two Weyl dipoles in Y(OH)3 exhibit the sextuple‐helicoid surface and hinge boundary states from the nonzero topological charge (±6) and the ...

The Symmetries of Equivalent Lagrangian Systems and Constants of Motion [PDF]

Journal of Sciences, Islamic Republic of Iran, 2011
In this paper Mathematical structure of time-dependent Lagrangian systems and their symmetries are extended and the explicit relation between constants of motion and infinitesimal symmetries of time-dependent Lagrangian systems are considered.
