Using Covers and Wetting Agents to Prevent Winter Injury of Ultradwarf Bermudagrass
… of turf can be caused by hydrophobic soils. Wetting agents are applied to actively growing ultradwarf bermudagrass greens to relieve symptoms of hydrophobic soils. Less is known about the effects late-fall wetting agent applications on dormant bermudagrass putting greens. This research aims …

Raman spectroscopic characterisation of inorganic fibres and particles and their coverage by wetting agents.
… of fibres. The spraying or injection of wetting agent into the material reduces the hazard associated with the removal process by aggregating the fibres together. The airborne concentration of fibres is then considerably reduced. Raman microspectroscopy has been shown to be a very …

The synthesis of aminophosphonic acid derivatives & related compounds
… they have been described as: complex-forming agents with sequestrating properties, extractants, wetting agents, pharmaceutical preparations, ion exchangers, herbicides, compounds with plant growth regulatory activity; inhibitors of aminopeptidases; as structural units in peptide analogues, …

Remediation of Soil Hydrophobicity on a Coastal USGA Sand-Based Golf Green
… during Trial II (p = 1). Ten of the thirteen wetting agent treatments significantly (p < 0.001) decreased soil hydrophobicity compared with the other wetting agent treated plots and the non-treated control. More frequent application of Cascade Plus resulted in a more significant reduction in …

Direct Force Measurement between Surfaces Coated with Hydrophobic Polymers in Aqueous Solutions and the Separation of Mixed Plastics by Flotation
… (PMMA) in the presence of different wetting agents (surfactants). The results show the possibility of separating plastics from each other by flotation, and a series of microflotation tests conducted on PS and PVC showed promising results.

Adhesion Fundamentals in Spotted Gum (Corymbia citriodora)
… focus on sensitivity to thermal deactivation. Wetting measurements were performed using the sessile drop method. Initial and equilibrium contact angles, time-dependent wetting, and surface energy were determined. Time-dependent wetting and equilibrium contact angles were most informative. …

Investigation of Coal Dust Remediation using a Surfactant in an Aqueous Solution
… miners and new dust regulations, surfactants or wetting agents have been used to aid in dust suppression. The surfactant facilitates the wetting process by lowering the surface tension and allowing the hydrophobic coal dust to come into contact with the water. One of the most straightforward and …

Field and Laboratory Studies on the Development and Control of Soil Water Repellency of Sand Root Zone Mixes
… droplet tests to determine soil hydrophobicity, wetting agent evaluations, and water retention based on percent organic matter were investigated. Greenhouse, field, and laboratory studies were conducted at Western Kentucky University beginning in 2000 and ending in 2001. The greenhouse study was …

Evaluation of collection protocols for the recovery of biological samples from crime scenes
… little development. This research has developed wetting agents which can be incorporated into most conventional swabbing protocols and has the potential to significantly improve both the recovery rate and stability of the DNA bearing samples. The main objective of this research was to improve the …
