Trigonometric derived rate of convergence of various smooth singular integral operators
Modern Mathematical MethodsIn this article, we continue the study of approximation of various smooth singular integral operators. This time the foundation of our research is a trigonometric Taylor’s formula.

Advanced Functional Materials, EarlyView.Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Advanced Functional Materials, EarlyView.Moiré band engineering in graphene/hexagonal boron nitride–based superlattices unlocks van Hove singularities (VHSs) for terahertz (THz) optoelectronics. Tuning the Fermi level near these singularities, associated with secondary neutrality points (SNPs), enhances the photothermoelectric response.

Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Osobliwe Równania Całkowe Termosprężystości
Engineering Transactions, 1965 The present paper contains a derivation of the integral representation of the general solution of coupled linear elasticity. It is assumed that the material and thermal constants are independent of the temperature and that the vibration is harmonic.

Tough Injectable Hydrogels Enabled by Integrating Rigid Homogeneous Framework With Flexible Chains
Advanced Functional Materials, EarlyView.Tough injectable hydrogels are constructed by integrating a rigid, homogeneous hyaluronic acid framework with flexible long‐chain connectors. This framework–flexible structure simultaneously enhances network uniformity and promotes effective energy dissipation by enlarging plastic deformation zones under compression.

An Innovation of 3-D non-singular boundary integral equations
, 2007 本論文旨在利用理論解析推導三維無奇異性瑕積分的邊界積分方程式，並配合數值模擬加以探討。有鑒於一般三維邊界元素法對於高階元素的瑕積分處理模式，多以適應性積分或極座標轉換為主，本論文提出另一種計算模式，將瑕積分轉換為一般積分加上部分沿著元素邊界的線積分，使得在瑕積分的計算能夠更精確及更簡潔。 其中，利用高斯通量定理，消除格林函數之奇異性。作法是僅需對原有的奇異性核函數加入一項使其異性消除，同時再將函數的解析積分值減去原方程式。由於格林函數的奇異性經過數學上的技巧加以消除 ...

Advanced Functional Materials, EarlyView.Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.

Asymptotic Solutions of the Phase Space Schrodinger Equation: Anisotropic Gaussian Approximation
, 2014 We consider the singular semiclassical initial value problem for the phase space Schrodinger equation. We approximate semiclassical quantum evolution in phase space by analyzing initial states as superpositions of Gaussian wave packets and applying ...
