An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

open access: yesAdvanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.

Market structure, market performance, and capacity: an excess capacity model

open access: yes, 1992
The objective of this paper is to discover whether the relationship between market structure and excess capacity is non monotonic. Excess capacity rises as market power rises; but after some point, according to the hypothesis, excess capacity falls as ...

In Situ Interfacial Assembly of Dynamic Semi‐Interpenetrating Biopolymer Networks for Robust and Mechanically Adaptive Droplet Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
A dynamic interfacial semi‐interpenetrating polymer network is constructed by sequential assembly of β‐sheet‐rich SF and CS‐RL. The SF framework provides mechanical strength, while dynamically associated CS‐RL enables local rearrangement, allowing droplets to rapidly reconfigure without loss of interfacial integrity.

Innovation, Market Structure and Economic Growth [PDF]

open access: yes
This paper presents a dynamic partial equilibrium model that endogenizes firms' investment decision on innovation: product innovation causes horizontal expansion growth, and process innovation causes vertical expansion growth.

Tantalum–Palladium Ultrathin Resistance Hydrogen Sensor

open access: yesAdvanced Functional Materials, EarlyView.
Nanoconfined Ta‐alloy thin films enable fast, reversible hydrogen sensing by suppressing unwanted phase transitions. A Ta0.88${\rm Ta}_{0.88}$Pd0.12${\rm Pd}_{0.12}$ sensing layer delivers hysteresis‐free detection from ppb to 100% H2${\rm H}_2$ at room temperature.

The Biotechnology Sector: "Bounds" to Market Structure [PDF]

open access: yes
This paper examines whether it makes sense to consider Sutton's "bounds" approach as a candidate theory for explaining the recent evolution of market structure in the biotechnology sector, and to speculate whether market structure will change if the ...

Endosomal Escape of siRNA Polyplexes: A Molecular Dynamics Perspective on Underlying Mechanisms

open access: yesAdvanced Functional Materials, EarlyView.
Molecular dynamics simulations reveal distinct endosomal escape mechanisms of siRNA nanoparticles, ranging from electrostatic membrane attachment to hydrophobic membrane fusion. Hydrophobic residues and anionic endosomal lipids emerge as key determinants of membrane disruption, linking molecular interactions to experimental delivery performance and ...

Market Integration and Industrial Structure: Home Market Effects Revisited [PDF]

open access: yes
Does market size matter for industrial structure? This paper generalises the theory on home market effects to reconcile the recent debate by allowing for an endogenous expenditure share on differentiated goods.

Role of the Recombination Zone in Organic Light‐Emitting Devices

open access: yesAdvanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...
