Field scale trials of a geosynthetic capillary break
… of a newly-developed product, a geosynthetic capillary break (GCB). The GCB was developed for use in engineered soil covers when a cover incorporating a capillary break effect would be desirable, but the coarse-grained material (gravel or sand) is unavailable or uneconomical. Engineered soil …

Spinning of synthetic spider silk-like fibers and ex vivo rheology of spider silk
… micro-rheometric devices (a microrheometer and a capillary break-up rheometer) enabled ex vivo rheology measurements of a spider's spinning solution (dope). Each apparatus was designed to accommodate the small quantities (-1 microliter) available from the spider's major ampullate gland. A shear …

Formation of microfibers and nanofibers by capillary-driven thinning of drying viscoelastic filaments
… microfibers and nanofibers by exploiting elasto-capillary thinning and stretching of macroscopic liquid bridges (Harfenist et al., Nano Lett., 4(10),2004). We develop a model of this process that describes the simultaneous visco-elasto-capillary thinning, stretching and drying of cylindrical …

Effects of polymer concentration and molecular weight on the dynamics of visco-elasto-capillary breakup
Capillary-break-up measurements of viscoelastic polymer solutions are performed using a Capillary Breakup Extensional Rheometer (CABER). The device consists of two coaxial plates which are used to form and hold a liquid bridge of the test fluid. An axial step strain is applied to the fluid by …

The Impact of a Planar Drainage Geocomposite in Unsaturated Soil
… content in the soil due to development of the capillary break effect. The column featured unique outlets to allow independent collection of the outflows for the DrainTube® mini-pipe and geotextile components to determine the efficiency of the geosynthetic to capture infiltration and divert it …

Determinación de las características de fricción en el contacto suelo-geotextil a diferentes succiones, mediante equipos de laboratorio singulares
… 5 kPa and 1 MPa. In addition, an insight of the “capillary break” effect caused by geotextiles embedded in the soil mass is included and the characteristic curves of the geotextiles have been obtained. Lastly, as a result of this research, the determination of the interface efficiency becomes …
