Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries

open access: yesAdvanced Materials, EarlyView.
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

Flax Composites With Improved Interfacial Strength Through Microbially Induced Mineral Precipitation

open access: yesAdvanced Materials, EarlyView.
A bio‐inspired biomineralization strategy introduces an additional hierarchy to flax fiber composites. By controlling microbe‐mediated mineral particle deposition through tuned salt concentrations, stress transfer within the natural fiber composite is enhanced.

Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

open access: yesAdvanced Materials, EarlyView.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

High Shear Rate Hemofiltration: Influence of Fiber Dimensions and Shear Rates

Artificial Organs, 1989
Abstract: The variation of ultrafiltration flow rate (QF) at high transmembrane pressure with inlet wall shear rate (γW) was found to be proportional to γW, with n ranging from 0.45 to 0.55, when γW increases up to 4,500 s‐1. To test whether long filters operated at high shear rates were more efficient than shorter ones for the same inlet blood flow ...

Slip at High Shear Rates

Physical Review Letters, 2008
There are contradictory published data on the behavior of fluid slip at high shear rates. Using three methodologies (molecular dynamics simulations, an analytical theory of slip, and a Navier-Stokes-based calculation) covering a range of fluids (bead-spring liquids, polymer solutions, and ideal gas flows) we show that as shear rate increases, the ...
