On the Convergence of a Family of Chlodowsky Type Bernstein-Stancu-Schurer Operators

open access: yesJournal of Function Spaces, 2018
We construct a new family of univariate Chlodowsky type Bernstein-Stancu-Schurer operators and bivariate tensor product form. We obtain the estimates of moments and central moments of these operators, obtain weighted approximation theorem, establish ...

Electroactive Liquid Crystal Elastomers as Soft Actuators

open access: yesAdvanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Generating Cell Surface Nucleated Hydrogels with an Artificial Membrane‐Binding Transglutaminase

open access: yesAdvanced Functional Materials, EarlyView.
Cell‐based therapies require advanced strategies to enhance cell delivery and bioactivity. Cell membrane engineering offers an avenue to impart new functions to delivered cells to boost their viability and function. Here, an artificial membrane‐binding transglutaminase is generated and biophysically characterized.

Kolmogorov-type inequalities for hypersingular integrals with homogeneous characteristics

open access: yesResearches in Mathematics
In this article we obtain sharp Kolmogorov-type inequalities that estimate the uniform norm of a hypersingular integral operator $$ D^{w,\Omega}_K f(x): = \int_{C} w(|t|_K) (f(x+t) - f(x))\Omega(t)dt, x\in C, $$ using the uniform norm of the ...

Electro‐Active Polymer Actuated Microfiltration Membranes: Design, Performance, and Particle Dynamics

open access: yesAdvanced Functional Materials, EarlyView.
The concept of foulant particle manipulation and detachment from active microfiltration membranes via voltage‐driven vibrations is introduced. Actuator components are initially integrated onto the filtration membranes using an airbrush spray printing technique.

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation

open access: yesAdvanced Functional Materials, EarlyView.
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

4D Printing of Self‐Immolative Polymers

open access: yesAdvanced Functional Materials, EarlyView.
The integration of self‐immolative polymers (SIPs) into light‐based 3D printed structures is presented as a new “living” 4D printing strategy. By exploiting their metastability and stimuli‐responsiveness, SIP‐containing printed objects can undergo rapid and triggered degrowth under ambient conditions and subsequent regrowth through polymer ...

Fully Bio‐Based Gelatin Organohydrogels via Enzymatic Crosslinking for Sustainable Soft Strain and Temperature Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Enzymatically crosslinked gelatin‐based organohydrogels, fabricated through a fully bio‐based and scalable process, exhibit exceptional strain and temperature sensing capabilities with minimal interference from environmental humidity. These transparent, stretchable, and ionically conductive materials operate without synthetic fillers or dopants.

Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...
