The complexity of numerical methods for elliptic partial differential equations

open access: yesJournal of Computational and Applied Mathematics, 1978
AbstractWe consider three Ritz-Galerkin procedures with Hermite bicubic, bicubic spline and linear triangular elements for approximating the solution of self-adjoint elliptic partial differential equations and a collocation with Hermite bicubics method for general linear elliptic equations defined on general two dimensional domains with mixed boundary ...

Using Heat‐Cool Processing to Change the Assembly and Photoconductive Properties of Perylene Bisimides

open access: yesAdvanced Materials Interfaces, EarlyView.
Here, we demonstrate how heating and cooling cycles modulate the self‐assembly of amino acid‐appended perylene bisimides (PBIs), influencing their structural and optoelectronic properties. With the use of small angle neutron scattering, AFM, UV–vis absorption spectroscopy and rheology it is determined how this affects their performance in perovskite ...

An inverse problem of Calderon type with partial data [PDF]

open access: yes, 2011
A generalized variant of the Calder\'on problem from electrical impedance tomography with partial data for anisotropic Lipschitz conductivities is considered in an arbitrary space dimension $n \geq 2$.

Finite element analysis for a coupled bulk-surface partial differential equation

open access: yes, 2013
In this paper, we define a new finite element method for numerically approximating the solution of a partial differential equation in a bulk region coupled with a surface partial differential equation posed on the boundary of the bulk domain.

A Sleeve Alters the Pressure‐Stretch Curve of a Hyperelastic Balloon to Enable Pre‐Programmed Sequencing

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Targeted Local Delivery via Fiber‐Embedded Flexible Microchannels Integrated with Film‐Based Implantable Probes

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, a fiber‐embedded drug delivery channel for implantable microprobes, demonstrating the first functional drug delivery system using flexible LCP‐based probes, is developed. The design incorporates fibers for site‐selective drug delivery and electrical functions. The utilization of monolithic thermal bonding simplifies fabrication.
