Transient growth calculations obtained directly from the Orr-Sommerfeld matrices [PDF]
arXiv, 2015 We introduce and validate an algorithm to compute transient amplication factors for the Orr-Sommerfeld-Squire linear theory for parallel two-phase flow. We further introduce direct numerical simulation as a way of comparing the linear theory with early-stage wave growth in simulations.

Inter‐Layer Diffusion of Excitations in 2D Perovskites Revealed by Photoluminescence Reabsorption
Advanced Functional Materials, EarlyView.Inter‐layer diffusion of photoexcitations is monitored in thin films of the 2D perovskite (PEA)2PbI4 by tracking time‐dependent changes in photoluminescence spectra induced by photon reabsorption effects. A low out‐of‐plane excitation diffusion coefficient of 0.26 × 10−4 cm2 s−1 is determined through 1D diffusion modeling.

On the theoretical prediction of microalgae growth for parallel flow [PDF]
arXiv, 2019 The established microalgae growth models are semi-empirical or considerable fitting coefficients exist currently. Therefore, the ability of the model prediction is reduced by the numerous fitting coefficients. Furthermore, the predicted results of the established models are dependent on the size of the photobioreactor (PBR), light intensity, flow and ...

Advanced Functional Materials, EarlyView.The Angiopep‐2 peptide density on polymeric nanoparticles significantly impacts blood–brain barrier (BBB) penetration. This study explores this nuanced relationship using various in vitro models and in vivo assays, revealing that dynamic models better predict BBB penetration.

Selective Desensitization of Growth Factor Signaling by Cell Adhesion to Fibronectin [PDF]
, 2007 Cell adhesion to the extracellular matrix is required to execute growth factor (GF)-mediated cell behaviors, such as proliferation. A major underlying mechanism is that cell adhesion enhances GF-mediated intracellular signals, such as extracellular ...

Quantification of growth factors in different platelet concentrates
Platelets, 2017 Concentrated growth factor (CGF), a new generation of platelet concentrate product, appears to have more abundant growth factors because of its special centrifugation process. However, there are few studies supporting this.

“Writing” Crystal Phases in Amorphous Calcium Carbonate via Laser‐Induced Patterned Transformations
Advanced Functional Materials, EarlyView.Laser‐induced crystallization enabling the patterning of amorphous calcium carbonate into various distinct phases is introduced. This approach provides spatial control over polymorph selection, both crystalline and amorphous, inspired by biomineralization pathways.
