From Water Vapor Transmission Rate (WVTR) to Intrinsic Water Vapor Permeability (WVP)

open access: yesAdvanced Materials, EarlyView.
Breathable membranes can appear less permeable when the measurement apparatus limits vapor transport. A calibrated four‐step model describes membrane permeation and apparatus effects as resistances in series under a common chemical‐potential driving force.

From social learning to culture : mathematical and computational models of cultural evolution [PDF]

open access: yes, 2013
Humans are unique in the extent and complexity of their cultures. As a species, we generate extensive knowledge and innumerable norms, attitudes, traditions, skills, beliefs and technologies that we share with those around us through teaching, imitation ...

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

open access: yesAdvanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

Weather Radars Reveal Environmental Conditions for High Altitude Insect Movement Through the Aerosphere

open access: yesRemote Sensing
High-flying insects that exploit tropospheric winds can disperse over far greater distances in a single generation than species restricted to below-canopy flight. However, the ecological consequences of such long-range dispersal remain poorly understood.

Conformal Coating and Transfer of 2D Nanomaterials via Dynamic Interface Engineering

open access: yesAdvanced Materials Interfaces, EarlyView.
This review discusses conformal coating and transfer of two‐dimensional (2D) nanomaterials with a focus on dynamic interface engineering. By actively regulating nanosheet transport and interfacial contact during film formation, recent dynamic coating strategies overcome the limitations of conventional passive approaches and enable geometry‐adaptive ...

Stem Cell Niche: iPSC-Based Assembloids for Modeling Human Hematopoiesis

open access: yes
The bone marrow (BM) niche is a highly specialized and dynamic microenvironment that tightly regulates hematopoiesis in both health and disease. In this chapter, we present a protocol for generating patient-specific 3D BM-mimicking assembloids, which offer precise control over cellular composition and genetic background.

Light‐Controlled Localized Delamination and Blistering of Azobenzene‐Containing Polymer Thin Films in an Aqueous Environment

open access: yesAdvanced Materials Interfaces, EarlyView.
When exposed to light of a defined wavelength, the photoisomerization of azobenzene chromophores leads to polymer reorientation, generating stresses that result in solvent‐facilitated localized delamination of the film from the substrate. Additionally, blisters that form spontaneously when exposed to an aqueous environment can be manipulated via ...
