Soft, Degradable, and Magnetic Microcarriers for Encapsulation and Guided Transport of Drugs and 3D Spheroids

open access: yesAdvanced Materials, EarlyView.
This work presents soft, degradable hydrogel microcarriers that combine magnetic responsiveness with the ability to host multiple therapeutic and cellular components. Produced by droplet microfluidics, the carriers maintain structural integrity during manipulation, permit controlled breakdown under physiological conditions, and enable guided motion for

Tangent modulus in numerical integration of constitutive relations and its influence on convergence of N-R method [PDF]

open access: yesApplied and Computational Mechanics, 2009
For the numerical solution of elasto-plastic problems with use of Newton-Raphson method in global equilibrium equation it is necessary to determine the tangent modulus in each integration point. To reach the parabolic convergence of Newton-Raphson method

Tangent Line and Tangent Plane Approximations of Definite Integral

open access: yes, 2017
Oftentimes, it becomes necessary to find approximate values for definite integrals, since the majority cannot be solved through direct computation.

Biodegradable Chitosan Films as Green Resists for Gold Nanowires Fabrication Through AFM‐Based Nanolithography

open access: yesAdvanced Materials Interfaces, EarlyView.
Schematic illustration of a sustainable nanofabrication process: chitosan derived from natural sources is used as a biodegradable thin film resist, patterned via Constant Pulse‐Assisted Force Lithography (CP‐AFL) to create tunable nanogrooves. These grooves template gold nanowire formation, enabling high‐resolution nanopatterning under ambient ...

Illumination by Tangent Lines

open access: yes, 2011
Let f be a differentiable function on the real line, and let P\inG_{f}^{C}= all points not on the graph of f. We say that the illumination index of P, denoted by I_{f}(P), is k if there are k distinct tangents to the graph of f which pass through P. In section 2 we prove results about the illumination index of f with f" (x)\geq 0 on \Re. In particular,

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials

open access: yesAdvanced Materials Interfaces, EarlyView.
Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

Large‐Area Printed PEDOT:PSS Shielding and Frequency Selective Surface (FSS) on Textiles

open access: yesAdvanced Materials Interfaces, EarlyView.
An all‐polymer e‐textile frequency selective surface (FSS) can present controlled shielding, presenting a competitive alternative to metal‐based inks. The results show how PEDOT: PSS‐based e‐textiles could be applied in RF devices for future wearable applications.
