Coaxial Melt Electrowriting

Advanced Materials Technologies, EarlyView.
Coaxial melt electrowriting is established to produce dual‐property microfibers with diameters spanning 1.6–29.2 µm. Stable coaxial laminar flow is preserved under electrohydrodynamic thinning, enabling controlled binary and gradient material switching within individual continuous fibers.

Omnidirectional Ultra‐Broadband Cu/TiO2 Metasurface Absorbers for High‐Efficiency Solar Thermal Conversion and Photothermal Plasmon‐Driven Catalysis

Advanced Optical Materials, EarlyView.
Metasurface shows selective solar–thermal energy conversion with high‐activity solar/laser‐driven chemistry. The breakthrough is co‐designing broadband FP‐cavity + plasmonic LSPR/SLR resonances in an ultra‐thin metamaterial so that it not only harvests the most efficient proportion of solar radiation but also suppresses mid and IR emissivity. Moreover,

Approximate Series Solution of Nonlinear Singular Boundary Value Problems Arising in Physiology

The Scientific World Journal, 2014
We introduce an efficient recursive scheme based on Adomian decomposition method (ADM) for solving nonlinear singular boundary value problems. This approach is based on a modification of the ADM; here we use all the boundary conditions to derive an ...

The Newton-Kantorovich Approximations for Nonlinear Singular Integral Equations with Shift

Journal of Integral Equations and Applications, 2002
Nonlinear singular integral equations with Carleman shift are considered in generalized Hölder spaces. The author proves convergence of the Newton-Kantorovich approximation for a class of singular integral equations for which the Fréchet derivative of the underlying nonlinear operator is locally Lipschitz continuous. Moreover, conditions sufficient for
