Silicone Phase Behavior Resolves the Softness–Surface Functionality Trade‐Off in Emerging Stretchable Electronics

open access: yesAdvanced Functional Materials, EarlyView.
Ultrasoft silicone elastomers often sacrifice surface functionality for mechanical compliance. In Mold Star, low‐molecular‐weight species form a dispersed phase that weakens the network and passivates the surface. Solvent extraction removes this phase, unexpectedly improving both extensibility and metallization performance, enabling conductive ...

Modulus of continuity and its application in classifying the smoothness of images. [PDF]

open access: yes, 2011
The problems of de-blurring, de-noising, compression and segmenta- tion are fundamental problems in image processing. Each of these prob- lems can be formulated as a problem to find some approximation of an initial image.

Estimates for Durrmeyer-type exponential sampling series in Mellin-Orlicz spaces

open access: yesDemonstratio Mathematica
This study examines Durrmeyer-type exponential sampling series to obtain a quantitative estimate by using the concept of the logarithmic modulus of smoothness defined with the help of a suitable modular functional on Mellin-Orlicz spaces.

Tannic Acid‐Modified Cellulose Nanofiber Reinforced Polymerizable Eutectogels for High‐Performance Stretchable Strain Sensors

open access: yesAdvanced Functional Materials, EarlyView.
A polymerizable deep eutectic solvent is reinforced with tannic acid‐modified cellulose nanofibers to construct a hierarchical dynamic eutectogel network. Synergistic covalent and reversible interactions impart ultrahigh stretchability, high ionic conductivity, broad temperature tolerance, self‐healing, and strong adhesion, enabling robust wearable ...

Mimetic Core‐Sheath Silk Sutures with Superior‐Strength for Pain Management, Anti‐Infection and Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
ABSTRACT Sutures are crucial for tissue approximation and wound healing. Besides their strength limits requirement, they often fail to effectively address complications like infection and pain. Inspired by natural silk's “core‐sheath” structure, our suture features a wet‐spun core of n zinc‐fortified silk fibroin fibers (RSF‐Zn2+) after drawing with ...

Modulus of supporting convexity and supporting smoothness

open access: yes, 2015
We introduce the moduli of the supporting convexity and the supporting smoothness of a Banach space, which characterize the deviation of the unit sphere from an arbitrary supporting hyperplane. We show that the modulus of supporting smoothness, the Bana{ś} modulus, and the modulus of smoothness are all equivalent at zero, the modulus of supporting ...

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

open access: yesAdvanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Dunkl analogue of Szász-mirakjan operators of blending type

open access: yesOpen Mathematics, 2018
In the present work, we construct a Dunkl generalization of the modified Szász-Mirakjan operators of integral form defined by Pǎltanea [1]. We study the approximation properties of these operators including weighted Korovkin theorem, the rate of ...

3D Bioprinted Breast Cancer‐Stroma Model with Tailored Migration‐Permissive Bioink Reveals Impact of Adipose‐Derived Stromal Cells on Cancer Cell Migration and Invasion Dynamics

open access: yesAdvanced Healthcare Materials, EarlyView.
A migration‐permissive bioink composed of methacrylated collagen type I and thiolated hyaluronic acid enables 3D bioprinting of breast cancer‐stroma models. Single‐cell tracking reveals that adipose stromal cells enhance tumor cell motility and stromal invasion, accompanied by collagen remodeling, and a shift in tumor cell morphology.
