The drop/bead and run test (FIGURE 6) clearly displays the difference in the level of oil repellency
between nano-treated and untreated.
Our objectives were to investigate: (1) whether dippers have contour feathers similar to those of aquatic or terrestrial bird families in terms of water repellency
and resistance to water penetration, and (2) if dippers that dive for their prey have a different feather structure from those that do not dive.
2009) noted that high-severity fires alter the vegetative cover and characteristics of mineral soil, making it difficult to separate the effects of fire-induced soil water repellency
from other changes in soil characteristics and surface cover.
The final factor to consider when analysing the impact of wildfire on total soil carbon and water repellency
is the change of these two variables across time.
Effects of coatings on water repellency
, color change, checking, and visual appearance were evaluated.
The target was to create surfaces with improved water and oil repellency
properties without affecting the physical appearance of the panels.
This algae and mildew resistant coating contains superior water repellency
Across southern Australia, large areas (~10 Mha) of formerly eucalypt-dominated lands cleared for agriculture experience varying degrees of water repellency
(Blackwell 2000; Harper et al.
8220;One of the benefits of our technology is the ability to change its functionality from repellency
to adhesion promotion.
An effective waterproof fabric provides much more than water repellency
Altopel F3 is based on hydrophobe-fortified polymers and provides a high level of water repellency
with laundering durability on a variety of fiber types and constructions.
Now researchers at the University of California, Riverside have identified the DEET-detecting olfactory receptors that cause the repellency
Although the mechanisms of action of HMOs against insects are still unclear, their effects are associated with factors such as physical disruption of epicuticular lipids, masking of oviposition stimulants, suppression of release of attractant host plant volatiles, induction of the release of repellent volatiles from plants, and direct repellency
of insect pests (Liu & Beattie 2002; Poerwanto et al.
Both are DWR treated for maximum water repellency
and are offered in Mossy Oak[R] Break-Up Infinity[R] and Realtree[R] Xtra[R].
Entomologist John Carroll, of BARC's Invasive Insect Biocontrol and Behavior Laboratory, and colleagues conducted several experiments to evaluate citrus compound repellency
