Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Dynamic programming is one of the main approaches to solve optimal control problems. It reduces the latter problems to Hamilton-Jacobi partial differential equations (PDE). Several techniques have been proposed in the literature to solve these PDE.

Carleman type inequalities and Hardy type inequalities for monotone functions
This Ph.D. thesis deals with various generalizations of the inequalities by Carleman, Hardy and Polya-Knopp. In Chapter 1 we give an introduction and overview of the area that serves as a frame for the rest of the thesis.

An integrated material platform combining engineered SiNx thin films and printable ZrO2 nanoparticle‐embedded resin enables broadband achromatic metalenses from the ultraviolet to visible range. The demonstrated meta‐optics achieve near‐diffraction‐limited focusing with minimal chromatic aberration.

Potassium–sulfur batteries are investigated using UV–vis spectroscopy to track the evolution of potassium polysulfide species at elevated temperature. The study reveals sulfur radical anions as key intermediates and shows how solvent composition and cell design influence polysulfide stability, redox behavior, and cycling performance, providing insights

A fluorenyl‐containing polyimine is introduced as a simple, scalable precursor for high‐performance carbon membranes. The precursor's intrinsic kinked structure enables defect‐free membrane formation with enhanced hydrogen permeance and excellent ideal selectivities for key industrial gas pairs (H2/N2, H2/CH4, and H2/CO2), offering a practical route ...

Chiral Phase Change Nanomaterials
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...
