Superhydrophobic surfaces have received increasing attention due to their excellent water repellency, but the fragile stability of superhydrophobic coatings has been a huge hindrance applications. In this work, we constructed layer mullite fibers on surface ceramic substrate using high-temperature molten salt. Then, obtained with contact angle greater than 150° via soaking sample an alcoholic s...

Silviculturists use a variety of techniques, including repellents, to reduce browse damage by white-tailed deer (Odocoileus virginianus) to valuable eastern hardwood seedlings. Systemic selenium, sodium selenite, was evaluated with captive whitetailed deer for its repellency in white ash (Fraxinus americana) and black cherry (Prunus serotina) seedlings. Selenium had no effect in reducing browsi...

Contact: Dr. Charles F. Palmer Ethox Chemicals [email protected] T +1 864 277 1620 They are used in many industrial and architectural applications. The hydrophobic nature of the alkyd polymer makes them good choices when water repellency is important. However, formulating alkyds into low VOC (volatile organic compound) waterborne coatings results in a number of problems, which can be minimised ...

Objective/purpose Evidence is emerging that human exposure to environmentally ubiquitous perfluorooctanoic acid (PFOA), used commonly for its household stain repellency characteristics, is associated with immunologic changes. Data from adults near an industrial PFOA disposal site demonstrated a strong negative correlation between blood PFOA concentrations and some immune responses. We propose t...

Insects under different stimuli from the environment modify behavioural responses due to changes in the sensitivity of neurons at the peripheral and/or at the central level of the nervous system. This phenomenon is called neuronal plasticity, and sensory adaptation is an example of it. An insect repellent is a chemical that produces oriented movements of the insects away from its source. In thi...

This research focuses on the novel synthesis of polyurethane (PU) foam surface functionalized with diatomaceous earth (DE) particles and non-fluoro octadecylsilane (C18), for use in enhanced clean-up oil spill contaminants from water. The modified PU has improved hydrophobicity, wettability, water repellency, biodegradability, which eliminates some drawbacks such as its hygroscopic nature, limi...

The rapid warming of the Arctic is changing conditions for agricultural activity in southwest Greenland markedly, which necessitates studies physical properties soil resource. Soil water repellency (SWR) a property that changes functional behaviour across soil-specific range water-content (W). Although SWR occurs worldwide, it has not been studied sub-arctic pasture and grass fields. Thus, aim ...

Liquid super-repellent surfaces, characterized by a low liquid–solid contact fraction, allow various liquids to bead up and freely roll off. Apart from liquid repellency, these surfaces feature several unique properties, including inter alia, self-cleaning, low-friction, anti-icing, anti-biofouling, making them valuable for vast array of applications involving liquids. Essential achieve such su...
