Ultrasonic Orbital Microforming—A New Possibility in the Forming of Microparts
Metals, 2018 The demand for very small metal parts is growing rapidly due to the development of micromechanisms. In microtechnology, the dimensions of scale parts are below 1 + c mm, where c varies based on the process type.

Bi-Doped Pd Aerogels with Tensile-Strain-Induced Cascade Orbital Hybridization Boost H2O2 Selective Activation for Efficient Pesticide Distinction [PDF]
ResearchThe selective activation of H2O2 into hydroxyl radicals (•OH) through the synergistic interplay between the nanozyme’s internal orbital interactions and external orbital coupling with intermediates presents an important scientific challenge.

Orbital Hypernormal Forms [PDF]
Symmetry, 2021 In this paper, we analyze the problem of determining orbital hypernormal forms—that is, the simplest analytical expression that can be obtained for a given autonomous system around an isolated equilibrium point through time-reparametrizations and transformations in the state variables.

Journal of Manufacturing and Materials Processing, 2022 Pin extrusion is a common process to realise pin structures in different geometrical dimensions for a subsequent joining operation. Nevertheless, the process of pin extrusion offers process limits regarding sheet thinning as a consequence of the punch ...

The orbit method and analysis of automorphic forms [PDF]
Acta Mathematica, 2021 We develop the orbit method in a quantitative form, along the lines of microlocal analysis, and apply it to the analytic theory of automorphic forms. Our main global application is an asymptotic formula for averages of Gan--Gross--Prasad periods in arbitrary rank.

Ultrafast Two-Electron Orbital Swap in Li Initiated by Attosecond Pulses
Ultrafast Science, 2023 A universal mechanism of ultrafast 2-electron orbital swap is discovered through 2-photon sequential double ionization of Li. After a 1s electron in Li is ionized by absorbing an extreme ultraviolet photon, the other 2 bound electrons located on 2 ...

Basic Forms and Orbit Spaces: a Diffeological Approach [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2016 If a Lie group acts on a manifold freely and properly, pulling back by the quotient map gives an isomorphism between the differential forms on the quotient manifold and the basic differential forms upstairs. We show that this result remains true for actions that are not necessarily free nor proper, as long as the identity component acts properly, where

Exact Analytical Form of Diatomic Molecular Orbitals
ACS Omega, 2022 We provide the exact analytical form of diatomic molecular orbitals, as given by the solutions of a single-electron diatomic molecule with arbitrary nuclear charges, using our recently developed method for solving Schrödinger equations. We claim that the best representation of the wave function is a factorized form including a power prefactor, an ...

Material Flow in Ultrasonic Orbital Microforming
Metals, 2019 Ultrasonic orbital microforming—UOM—uses the broadly understood idea of orbital forging but uses very different laws of physics. The only shaping force in this process is the inertia force resulting from the acceleration in the rotary motion ...
