The preconditioned conjugate gradient method with incomplete factorization preconditioners [PDF]
, 1996 We present a modification of the ILUT algorithm due to Y. Saad for preparing incomplete factorization preconditioner for positive definite matrices being neither diagonally dominant nor M-matrices.

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells
Advanced Materials, EarlyView.Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

An Improved 3D Magnetization Inversion Based on Smoothness Constraints in Spherical Coordinates
Magnetochemistry, 2022 In the inverse problem, the traditional way to obtain a stable solution is based on the maximum smoothness criteria. However, this approach cannot generate clearer and more focused images.

Controlled Synthesis of Tri‐ and Multi‐Doped Graphene
Advanced Materials Interfaces, EarlyView.This review systematically evaluates synthesis routes for tri‐ and multi‐doped graphene, from hydrothermal and pyrolysis methods to flash Joule heating, critically assessing how each governs dopant incorporation, bonding configuration, and resulting electronic properties.

Fast iterative solvers for PDE-constrained optimization problems [PDF]
, 2013 In this thesis, we develop preconditioned iterative methods for the solution of matrix systems arising from PDE-constrained optimization problems. In order to do this, we exploit saddle point theory, as this is the form of the matrix systems we wish to ...
