Characterization of various zinc oxide catalysts and their activity in the dehydration-dehydrogenation of isobutanol [PDF]
Journal of the Serbian Chemical Society, 2008 Mono and bifunctional zinc oxide catalysts were prepared to study their activity in the catalytic conversion of isobutanol. The prepared catalysts were characterized by X-ray diffraction analysis and nitrogen adsorption measurements.

Data refinement refined resume [PDF]
, 1986 We consider the original work of Hoare and Jones on data refinement in the light of Dijkstra and Smyth's treatment of nondeterminism and of Milner and Park's definition of the simulation of Communicating Systems. Two proof methods are suggested which we hope are simpler and more general than those in current use.

Refining Vegetable Oils: Chemical and Physical Refining [PDF]
The Scientific World Journal, 2022 This review presents recent technologies involved in vegetable oil refining as well as quality attributes of crude oils obtained by mechanical and solvent extraction. Usually, apart from virgin oils, crude oils cannot be consumed directly or incorporated into various food applications without technological treatments (refining). Indeed, crude oils like
