Fluorosurfactants are chemical compounds composed of two parts: polar hydrophilic head and highly hydrophobic fluorocarbon tail. Fluorocarbons have outstanding physico-chemical properties determined by the very special properties of fluorine. The specific properties of fluorocarbon chains (F-chains) as compar...
Adelhelm LubriCoat NA is headed up by Adam Berres (left) and Dan Drayna (right). For more, visit their website.All Teflon™ coating varieties are “fluoropolymers,” which are fluorocarbon-based polymers with multiple carbon-fluorine bonds. This classification means that they possess a number...
Why is carbon the backbone of organic chemistry? Why is glycine hydrophobic? Why is the water molecule so important to organisms? Why do gases condense when they are cooled? Why is hydrogen bond important in water? Why are hydrogen bonds important in biology? Why are some substances not able...
Hydrogen bonding is a type of dipole-dipole attraction between a lone pair on an electron rich donor atom, particularly nitrogen, oxygen, or fluorine, and partially positively charged hydrogen atom.Answer and Explanation: The drop of water wants to minimize its energy....
Alongside a growing number of outdoor gear brands choosing to go PFC-free, the brand synonymous with water repellent fabrics – Gore-Tex – is too. Going PFC-free sounds absolute but it's not always. For example, Páramo uses a Nikwax DWR that is completely free of fluorine. Meanwhile the...
As a touch product, mobile phones usually add a“hydrophobic and oleophobic coating”on the screen’s surface to avoid becoming a “fingerprint collector” and affecting use. The current standard hydrophobic and oleophobic layer uses stable fluorine-containing coatings, whichwill not react with alcohol...
a) Drugs can be made more hydrophobic such that they act in the brain and not peripherally. b) Drugs can be made more hydrophilic such that they act peripherally and not in the brain. c) Drugs c What is the function of the HIV-1 ...
