The n-heptane hydroconversion over the palladium impregnated catalysts was investigated in the temperature range from 250°C to 350°C at a pressure of 3 bar. The increasing number of strong acid sites was reflected in an enhanced catalytic activity. The selectivity to isomerization was around 95...

Anionic species get involved in surface chemical reaction with the binding sites of the adsorbent ferric hydroxides surfaces, which remain predominantly positive up to a pH level of 7; As(III) species being uncharged at this pH level cannot be bound to the adsorbent surface. This explains ...
46. Kumar and co-workers have previously reported the generation of 4–5 mers and 12–24 mers from lauric acid along a non-fibril formation pathway22. More importantly, using carbon chain lengths of C9-C12 fatty acids (FAs), they established that below (non-micellar), near (pseudo-...

variety of domestic animals. The major portion of its structure varies little between mammalian species; and the positions of the distinguishing and structurally significant amino acid residues (glycine, proline, and hydroxyproline), are uniquely consistent in the main helical portion of the collagen...
Non-porous ceramic catalyst supports, roughened by treatment for several hours with 30 percent by weight sodium hydroxide solution at 60°C, or by treatment with hydrofluoric acid-fluoride etching media have also been used successfully as catalyst supports for platinized and polytetrafluoroethylene coate...
such as RUSLE, have been applied to uncultivated and cultivated sites in southeast Australia (Martinezet al., 2009; Tenget al., (2016)55). To this end, we modified a novel method for rural areas proposed by Mouriet al. (2014a)1to Fukushima-derived137Cs in the urban region of Tokyo,...
(2008) reported an increase in solubility of ions due to the excessive secretions of gluconic acid and ketogluconic acid produced by Burkholderia sp., Pseudomonas sp., Bacillus firmus, and Rhizobium sp. Liu et al. (2019) studied the effect of pH on biodegradation characteristics of thermophilic...
