Cell Membrane Vesicle Camouflaged Artificial Cells
Advanced Functional Materials, EarlyView.Artificial cells camouflaged with a cell membrane vesicle coating are able to assemble into synthetic aggregates that exhibit rudimentary communication capabilities. Additionally, when these artificial cells are equipped with antioxidant capabilities, they are able to protect the intracellular homeostasis in HepG2 cells present in semi‐synthetic ...

Effect of the Blood Vessel Viscoelasticity on Periodic Blood Pressure Wave Propagation
Journal of Fluid Science and Technology, 2009 Clinical arterial stiffness indexes such as PWV (pulse wave velocity) or PP (pulse pressure), which are obtained by analyzing blood pressure pulse waveforms in vivo, are used in the prognosis of cardiovascular diseases and thus analyses of pulse waveform

Advanced Functional Materials, EarlyView.Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Boussinesq's problem of viscoelasticity [PDF]
Terra Nova, 1991 ABSTRACTWe consider an isochemical, isentropic, incompressible fluid half‐space and study quasistatic viscoelastic perturbations, induced by two‐dimensional (2D) surface loads, of a hydrostatic initial state. In view of the regional or local scale required for deformations of planets to be amenable to the half‐space approximation, the model is assumed ...

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels
Advanced Functional Materials, EarlyView.A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

Rayleigh-Taylor Instability in Viscoelastic Fluids [PDF]
arXiv, 2013 In this paper I analyze the onset of Rayleigh-Taylor instability between two linear viscoelastic fluids assuming that the perturbations at the interface are small. In the first half, the paper analyzes a stratified viscoelastic fluid in which I prove that the perturbations rise or fall exponentially without oscillating.

Impact of the Microstructure of Polymer Drag Reducer on Slick-Water Fracturing
Geofluids, 2017 Many studies have focused on the drag reduction performance of slick-water, but the microdrag reduction mechanism remains unclear since the microstructure of the drag reducer and its effect on this mechanism have not been well studied. In this study, the
