Crossing the Oxo‐Peroxo Wall for Selective Electrochemical Epoxidation
Advanced Science, EarlyView.The classical Oxo‐Wall concept is extended to an Oxo–Peroxo Wall framework, showing that meta‐stable oxo species favor peroxo and superoxo formation, decoupling from oxygen evolution reaction (OER). This new understanding enables selective C‐C bond oxidations and provides a predictive alternative oxidation reaction (AOR) volcano for designing metal ...

Spectral curve fitting of dielectric constants
AIP Advances, 2017 Optical constants are important properties governing the response of a material to incident light. It follows that they are often extracted from spectra measured by absorbance, transmittance or reflectance.

A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

SUT Journal of Mathematics, 2011 In this paper, we determine the wave front sets of solutions to the Schrödinger equations of the Schrödinger evolution operator of a free particle and of a harmonic oscillator by using the representation of the Schrödinger evolution operator of a free ...

Advanced Science, EarlyView.An innovative molecular spatial‐positioning shimming strategy is developed to optimize the electrical properties of poly(vinylidene fluoride) (PVDF). By intercalating polyethylene wax (PE wax) short‐chain molecules into PVDF's free volume, the film achieves a significantly enhanced energy density of 32.67 J cm−3.

Stabilization of the Benzene Radical Trianion in an Inverse‐Sandwich Yttrium Complex
Angewandte Chemie, EarlyView.A new type of benzene anion state is born: The unprecedented benzene radical trianion embedded in an inverse‐sandwich yttrium complex was synthesized by a one‐electron chemical reduction of its benzene dianion precursor using potassium graphite in the presence of [2.2.2]‐cryptand.

Advanced Science, EarlyView.High‐pressure investigations uncover the structural determinants of luminescence intensity and shifts in aramids, establishing intrinsic intramolecular rotation as a reliable predictor of their piezofluorochromic behavior. Leveraging this insight, conjugation modulation is proposed as a precise strategy to tune their piezofluorochromic properties ...

Hybrid coherent control of magnons in a ferromagnetic phononic resonator excited by laser pulses
Physical Review ResearchWe propose and demonstrate the concept of hybrid coherent control (CC) whereby a quantum or classical harmonic oscillator is excited by two excitations: one is quasiharmonic (i.e., harmonic with a finite lifetime) and the other is a pulsed broadband ...
