Organic Permeable Base Transistors—Reliable Large‐Scale Anodization for High Frequency Devices

open access: yesAdvanced Functional Materials, Volume 35, Issue 17, April 25, 2025.
Electrochemical anodization is optimized for organic permeable base transistors (OPBTs), achieving an unprecedented 87% yield and reproducibility for vertical organic transistors (VOTs) on a 15 x 15 cm wafer. Controlled Al base oxidation ensures a median transconductance of 10−3 S, leakage current below 10−9 A, current gain of 106, and transit ...

Lie Symmetry Analysis of a Nonlinear Black–Scholes Equation in Illiquid Markets

open access: yesInternational Journal of Mathematics and Mathematical Sciences
We have conducted comprehensive Lie symmetry analysis of a nonlinear Black–Scholes equation that arises in illiquid markets. The equation incorporates nonlinearities arising from market constraints, such as transaction costs and liquidity effects.

Potential Nonclassical Symmetries and Solutions of Fast Diffusion Equation

open access: yes, 2006
The fast diffusion equation $u_t=(u^{-1}u_x)_x$ is investigated from the symmetry point of view in development of the paper by Gandarias [Phys. Lett. A 286 (2001) 153-160].

Mediation of Oxidation and Spin States of Fe/P‐CoO2 Core–Shell Structures Catalysts for Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, Volume 35, Issue 16, April 18, 2025.
Fe‐cationic and P‐anionic coordination, as fabricated in Co0.75Fe0.25P/MWCNTs, effectively optimizes the adsorption of OER intermediates (OH*, O*), promoting direct O*─O* coupling and avoiding the formation of unstable OOH* intermediate. This process is accompanied by an asynchronous transfer of electrons and protons, resulting in the formation of a ...

A group theoretic approach to shear-free radiating stars

open access: yes, 2015
A systematic analysis of the junction condition, relating the radial pressure with the heat flow in a shear-free relativistic radiating star, is undertaken. This is a highly nonlinear partial differential equation in general.

Recent Advances in Single‐Atom Catalyst for Solar Energy Conversion: A Comprehensive Review and Future Outlook

open access: yesAdvanced Functional Materials, Volume 35, Issue 16, April 18, 2025.
This review highlights the potential of single‐atom catalysts in three key photocatalytic reactions: the hydrogen evolution reaction (HER), nitrogen reduction reaction for ammonia synthesis, and carbon dioxide reduction reaction (CO2RR) for chemical fuels.

Lie point symmetries and conservation laws for a Gardner type system [PDF]

open access: yesarXiv, 2019
We determine the Lie point symmetries of a Gardner type system and establish its nonlinear self-adjointness. We then construct conservation laws via Ibragimov's Theorem.

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow

open access: yesAdvanced Functional Materials, EarlyView.
Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

Off‐Stoichiometry Engineering of the Electrical and Optical Properties of SrNbO3 Using Oxide Molecular Beam Epitaxy

open access: yesAdvanced Functional Materials, EarlyView.
The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...

Hidden and Not So Hidden Symmetries

open access: yesJournal of Applied Mathematics, 2012
Hidden symmetries entered the literature in the late Eighties when it was observed that there could be gain of Lie point symmetry in the reduction of order of an ordinary differential equation. Subsequently the reverse process was also observed.
