Rubber Chemistry and Technology, 1937
Abstract Superior water resistance of well-cured Neoprene, like that of natural rubber, depends upon the absence of water-soluble ingredients and agents that are capable of absorbing water. It has been shown that the water resistance of Neoprene varies greatly with different activating agents.

Water resistant audible signal
The Journal of the Acoustical Society of America, 2006The invention is an modified audible signal, such as a piezoelectric noise-making and audible signaling device, which further includes a hydrophobic covering material, such as polytetrafluoroethylene (PTFE). The hydrophobic covering material is known to be water resistant, but does not effect the sound of the audible signaling device, thereby delaying ...

Kapitza resistance at water–graphene interfaces
The Journal of Chemical Physics, 2020Heat transfer across fluid–solid interfaces in nanoconfinement has received significant attention due to its relevance in nanoscale systems. In this study, we investigate the Kapitza resistance at the water–graphene interface with the help of classical molecular dynamics simulation techniques in conjunction with our recently proposed equilibrium ...

Aggregation-Resistant Water-Soluble Gold Nanoparticles
Langmuir, 2007Stable, water-soluble gold nanoparticles, Au NPs, having an average diameter of ca. 4 nm, were prepared using place exchange reactions. The nanoparticles, capped with novel zwitterionic disulfide ligands, showed remarkable stability in saline media with salt concentrations as high as 3.0 M. Similarly, the Au NPs did not precipitate out of solution when

Water-Resistant, Water Vapor Permeable Cotton Fabrics1
Textile Research Journal, 1957The water vapor transmission property of the cotton fiber is used to greatest advantage in plastic-coated, water-resistant fabrics when the coatings are relatively light, and are as much as possible located inside the fabric structure, with cotton exposed on each surface.

Antibiotic resistance genes in water environment
Applied Microbiology and Biotechnology, 2009The use of antibiotics may accelerate the development of antibiotic resistance genes (ARGs) and bacteria which shade health risks to humans and animals. The emerging of ARGs in the water environment is becoming an increasing worldwide concern. Hundreds of various ARGs encoding resistance to a broad range of antibiotics have been found in microorganisms

Water-Resistant Breathable Fabrics
Journal of Coated Fabrics, 1992The first part of this paper covers the questions: How can we obtain WBFs (waterproof breathable fabrics)? and What is available? A description of the technique to obtain such fabrics with a statement of general advantages and disadvantages is covered. There are three techniques: 1. High-density fabrics 2.

Water Resistance and Extended Wear Sunscreens
Dermatologic Clinics, 2006The effectiveness of a sunscreen product can be reduced by sweating, friction, water immersion, or any other force that has the potential to remove the product from the surface of the skin. Substantivity (resistance to removal by water or sweat) along with durability (resistance to removal by wear) during physical activity are important aspects of ...
