The effects of abrasion on liquid-fabric interaction of selected nonwoven fabrics
… effects of different abrasion treatments on the liquid-fabric interaction of selected nonwoven barrier fabrics. The abrasion treatments included moderate and severe abrasion, flat and flat/flex abrasion, and dry and wet abrasion. The liquid-fabric interactions included wetting/wicking, retention, …

Activation of Release by Hydration in Pharmaceutical Tablets Studied by Terahertz Pulsed Imaging
… the most common pharmaceutical dosage forms. The liquid ingress into a tablet is considered to be the first, and often rate-determining, step for tablet disintegration and subsequent drug dissolution. Even for tablets that do not disintegrate (e.g. sustained release tablets), hydration of the oral …

Characterization of spray and combustion of diesel-alcohol blends in a constant volume chamber
… a copper vapor laser. The results show that the liquid penetration was reduced by the high percentage of ABE in the blends. At the same time, the soot formation was reduced significantly by increasing oxygen content in the ABE fuel. Even more interesting, a soot-free combustion was achieved by …

A detailed, stochastic population balance model for twin-screw wet granulation
… coagulation, breakage, consolidation, liquid penetration, primary particle layering and transport. The model’s predictive power is assessed over a range of liquid-solid mass feed ratios using existing experimental data and is demonstrated to qualitatively capture key experimental trends …

Experimental investigation of liquid fragmentation in hypersonic cross flow
… experimental investigation carried out to study penetration and fragmentation of liquid injected into Mach 6 hypersonic cross flow. Flow topology, shock and vortex systems, fragmentation and atomization mechanisms are investigated using high-speed photography, Schlieren photography, flow …

Long-Term Performance of Polymeric Materials in Civil Infrastructure
… that is commonly used to store a wide range of liquids ASTs. Currently, there are no established protocols for carrying out non-destructive testing (NDT) and assessment of HDPE ASTs for regular inspections, so this study investigated the viability of using infrared thermography (IRT) and …

Influence of surface tension and concentration of a non-ionic surfactant on the barrier effectiveness of a microporous polypropylene fabric for pesticide protective clothing
… (θ), made by a 5-<i>μ</i>L drop of each test liquid on the test fabric, were measured. Barrier effectiveness was evaluated from the capillary penetration, wicking, and wetting characteristics of the fabric using the surfactant solutions at various concentrations. Wetting characteristics were …

Continuos Doping of La2CuO4+x Thin Films
… a doping technique involving gating with ionic liquids to systematically and continuously tune the Tc of superconducting La2CuO4+x thin films. We probe both the transport properties and the penetration depth of these samples and find that Homes scaling, lambda^-2 ~ sigma*Tc, is obeyed, …
