Electrothermally modulated stop-go microvalves for capillary transport systems [PDF]
In this article, we show a novel approach to implementing valving action in a dynamically evolving capillary filling process, by exploiting alternating current electrothermal (ACET) mechanism. The surfaces of the top and bottom walls of the capillary are asymmetrically patched with two different wettabilities. Our observations reveal that by exploiting

Nanofibrils are considered the universal building blocks of spider silks. In this work, the thinnest natural spider silk nanofibrils are imaged, measured, and mechanically tested for the first time. Gaining insight into the mechanics of silk at the nanoscale is important.

Biomimetic Spider Silk by Crosslinking and Functionalization with Multiarm Polyethylene Glycol
Bioconjugation of recombinant mini‐spidroins with multiarm polyethylene glycol (PEG) is employed to produce artificial spider silk, which can be crosslinked and chemically functionalized while maintaining a biomimetic spinning approach. The best fibers exhibit enhanced tensile strength and/or extensibility, both contributing to an increased toughness ...

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...

A sustainable aqueous wet spinning method enables an efficient production of artificial spider silk fibers which show excellent extensibility and remarkable toughness. A highly specific and efficient biomolecular click reaction is employed to functionalize these fibers under mild conditions, which offers a promising method to construct multi‐functional

Trapping and Mobilization of Residual Fluid During Capillary Desaturation in Porous Media [PDF]
We discuss the problem of trapping and mobilization of nonwetting fluids during immiscible two phase displacement processes in porous media. Capillary desaturation curves give residual saturations as a function of capillary number. Interpreting capillary numbers as the ratio of viscous to capillary forces the breakpoint in experimental curves ...

2D Vermiculite Nanolaminated Membranes for Efficient Organic Solvent Nanofiltration
Intercalating multivalent cations into 2D vermiculite nanolaminates significantly improves the structural stability and sieving capabilities of membranes in both aqueous and organic media, rendering them effective for organic solvent nanofiltration. Abstract Membrane separation technology has found widespread application in molecular sieving and water ...

Copper sulfide based electrocatalysts for CO2 conversion are selective for production of formate as major product. Transformations under electrochemical conditions result in significant sulfur loss, and this study examines the nature of how persistent, residual sulfur (observed as surface SO42– species and S dissolved in the electrolyte) can sustain ...
