Abstract : The adsorption of As(III), As(V), Se(IV) and Se(VI) by seawater neutralized red mud and alum water treatment sludge was investigated and compared using the batch adsorption technique. For water treatment sludge, adsorption of As(V), Se(IV) and Se(VI), at equimolar concentrations of added metalloid, declined with increasing pH. The decline was rapid above pH 4.0 for Se(VI), above pH 5…
† Background and Aims: Aluminium is toxic in acid soils because the soluble Al3+ inhibits root growth.Amechanism of Al3+ tolerance discovered in many plant species involves the release of organic anions fromroot apices. The Al3+ - activated release of citrate from the root apices of Al3+ -tolerant genotypes of barley is controlled by a MATE gene named HvAACT1 that encodes a citrate transpor…
Abstract We have recently developed a database, pDAWG, focused on information related to plant cell walls. Currently, pDAWG contains seven complete plant genomes, 12 complete algal genomes, along with computed information for individual proteins encoded in these genomes of the following types: (a) carbohydrate active enzyme (CAZy) family information when applicable; (b) phylogenetic trees of …
To obtain a high biodiesel yield, the conditions of transesterification of vegetable oil with supercritical methanol are harsh. The reaction temperature is required between 350 and 400 °C, and the reaction pressure is required above 20 MPa. To reduce the operating temperature and pressure, many researchers adopted various methods, such as the selection of a new reactor, the addition of a co…
ABSTRACT Bisimidazolium ionic liquids [C10(m2im)2(NTf2)2, C10(m2im)2(PF6)2, and C10(m2im)2(BF4)2] with different anions were evaluated as the antiwear additives in poly(ethylene glycol) at room temperature. Results showed that they could effectively reduce the friction and wear of sliding pairs compared with the cases without these additives. Especially, C10(m2im)2(NTf2)2 showed better antiwe…
