Endothelial Cells Angiogenesis in Sulfated Glycosaminoglycan (GAG) Hydrogels Enhanced by Bioactive Glass‐Released Ions

open access: yesAdvanced Functional Materials, EarlyView.
A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...

Energy-Capital Substitution: A General Equilibrium Analysis [PDF]

open access: yes
We consider an economy which imports energy from a monopolistic price-setter. The domestic general equilibrium of this economy adjusts in response to the price of energy.

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites

open access: yesAdvanced Functional Materials, EarlyView.
Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.

Price elasticity of rail freight services: the case of Poland

open access: yesTransportation Research Interdisciplinary Perspectives
This paper examines the price elasticity of demand for rail freight in Poland and its implications for infrastructure pricing. We address a gap in Eastern European rail transport literature by estimating how Polish shippers respond to changes in rail ...

Empirical Evidences from a Coffee Paradox: An Export Supply/Price Asymmetry Approach [PDF]

open access: yes
This paper aims to determine the solidity of the notion of the "coffee paradox" using annual data from 1977 to 2007. In the confines of an export supply model, we analyze the effects of export coffee price on export volume.

Viscoelasticity‐Induced Controllable Periodic Meso‐Textures of Liquid Crystal Polymers in Additive Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
Viscoelasticity‐driven instabilities are harnessed to create tunable, periodic textures in 3D‐printed liquid crystalline polymers. This study illustrates how processing parameters control these spontaneous meso‐scale patterns. These unique structural architectures unlock new possibilities for functional devices, ranging from photonic components to ...

Analysis of Subscription Demand for Pay-TV [PDF]

open access: yes
In this paper, we will conduct an analysis from an empirical perspective concerning broadcasting demand behavior and characteristics. More concretely, we will assume three options (subscription patterns), namely, nonsubscription, cable TV subscription ...

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...
