wood vinegar is the aqueous phase of the liquid produced during the slow pyrolysis of wood.it has the potential to be used as a pesticide against various weeds, insects and molluscs. due to divergentfeedstocks, pyrolysis processes and storing conditions, the chemical composition of wood vinegar variesbetween producers and time. the aim of our current study was to use the copse snail arianta arb...

Cyclones are devices used in various industries to remove particulate matter from gases and liquids. Commonly the power generation, cement, mining industries, cyclones improve efficiency longevity of equipment by removing dust other small particles that can cause wear damage. Among centrifugal separation, reverse-flow primarily for particle which reach heights several meters on an industrial sc...

The present work is motivated by the effort to understand basic processes occurring in three-phase systems where small bubbles interact with large particles. simplified system of a single bubble rising stagnant liquid and colliding solid surface studied. effect two specific surfactants, ?-Terpineol n-Octanol, investigated. Two independent measurements are combined: (i) bubble–solid collision ex...

bifunctional acidic ionic liquids, having both h-imidazolium and -so3h groups as cation moieties (h-bfails) and cf3so3- as anion, were synthesized in high yields. these h-bfails showed significant hydrophilic properties, lower acidity and higher thermal stability relative to common ionic liquids, due to their unique structures. the (propyl or butyl-3-sulfonic) imidazolium trifluoromethane sulfo...
