Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Implantable Ionic Memristors Based on Natural Polymer Heterojunctions

open access: yesAdvanced Functional Materials, EarlyView.
We report an implantable natural polymer‐based ionic memristor composed of hyaluronic acid, chitosan, and PDMS. The device achieved 98.94% accuracy in MNIST classification while reducing training time by 36.8% compared with a conventional artificial neural network (ANN).

$L^p$ - $L^q$ estimates for damped wave equations with odd initial data

open access: yesElectronic Journal of Differential Equations, 2005
We study the Cauchy problem for the damped wave equation. In a previous paper [16] the author has shown the $L^p$ - $L^q$ estimates between the solutions of the damped wave equation and the solutions of the corresponding heat equation.

From Photoalignment to Structured Light: Liquid Crystal Platforms for Beam Shaping and Complex Wavefronts

open access: yesAdvanced Functional Materials, EarlyView.
Photoaligned and photopatterned liquid crystal platforms provide programmable control of optical phase, polarization, and spin‐orbit interactions, enabling compact generation of structured light and complex wavefronts. This review highlights how tailored molecular orientations transform simple beams into designed optical fields, opening versatile ...

Approximate asymptotic integration of a higher order water-wave equation using the inverse scattering transform [PDF]

open access: yesNonlinear Processes in Geophysics, 1997
The complete mathematical and physical characterization of nonlinear water wave dynamics has been an important goal since the fundamental partial differential equations were discovered by Euler over 200 years ago.

Nanoscale Spatial Tuning of Superconductivity in Cuprate Thin Films via Direct Laser Writing

open access: yesAdvanced Functional Materials, EarlyView.
Maskless direct laser writing enables local control of oxygen stoichiometry in epitaxial YBCO thin films under ambient conditions. Sub‐micrometer grayscale patterns with tunable optical response and superconducting transport properties are achieved.

Distributed Control of a Vibrating String in Response to Pointwise Force Application

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi
The problem of controlling the vibrations of a string by a discrete applied force is considered. The vibrations of the string are modeled by the linear wave equation and the control is provided by an added force term.
