Many natural and industrial processes involve fluid flow at a three phase interface between liquid, solid and gas. When the liquid is forced to move rapidly over the solid surface, the physical mechanisms governing contact line motions are multi-phase and ...
Before a droplet can contact a surface during impact, it must first displace the air beneath it. Over a wide range of impact velocities, the droplet first squeezes the air into a thin film, enhancing its resistance to drainage; this slows the progress of t ...
The objective of this study is to analyse the mechanical and durability properties of a high-performance mortars based on low grade kaolin clay and the effect of electrical conductivity and pore microstructure on the chloride penetration resistance. A tota ...
Zabinskiite, ideally Ca(Al0.5Ta0.5)(SiO4) O, was found in a Variscan granitic pegmatite at Pilawa Gorna, Lower Silesia, SW Poland. The mineral occurs along with (Al, Ta, Nb)-and (Al, F)-bearing titanites, a pyrochlore-supergroup mineral and a K-mica in co ...
The structure of solid-ionic liquid (IL) interfaces has been characterised with unprecedented clarity by employing a range of atomic force microscopy (AFM) imaging techniques and tip pressures appropriate for the system under study. Soft contact and amplit ...
Accurate control of groundwater pH is of critical importance for in situ biological treatment of chlorinated solvents. This study evaluated a novel approach for buffering subsurface pH that relies on the use of silicate minerals as a long-term source of al ...
We investigate processing-microstructure relationships in the production of Al2O3 particle reinforced copper composites by solidification processing. We show that during production of the composites by gas-pressure infiltration of packed Al2O3 particle pre ...
TiO2/nylon fabrics were investigated for methanol degradation under UV light irradiation. TiO2 Degussa P-25 was supported on nylon by immersing the nylon in sol-gel TiO2 and silicone. The TiO2 layers on the nylon were explored as a function of the time of ...
TiO2 modified polyester photocatalysts were prepared by immersion. drying and curing of the polyester in TiO2 containing suspensions under different experimental conditions. The structure of TiO2 layers on the polyester varied according to the time of imme ...
Using friction force microscopy, we compared the nanoscale frictional characteristics of atomically thin sheets of graphene, molybdenum disulfide (MoS2), niobium diselenide, and hexagonal boron nitride exfoliated onto a weakly adherent substrate (silicon o ...
