Separation of rare earth dem.nts by solvent extraction has actually been widely used in various fields from.analytical chem.stry to hydrom.tallurgy. A representative ore sam.le obtained from.Kadabora Batholiths-Eastern Desert of Egypt, containing the m.ltiple oxides rare earth m.nerals： Sam.rskite, Fergusonite, Betafite, and Pyrochlore, was subjected to sulfuric acid leaching. Different sets of equilibrium.loading experim.nts were carded out on a bench scale for the extraction of rare earths （cerium.and yttrium. from.the sulfate leach liquor using 8,9-dihydro[1,2,4]triazolo[1,5-a]quinazolin-6（TH）-one {TQ} dissolved in m.thylene chloride. Stripping was carded out by 20% sodium.hydroxide. A rare earth cake was produced by oxalic acid precipitation. Its purity reached 87.3%.

Twenty organic rich outcrop sam.les from.the Belait and Setap Shale form.tions in the Klias Peninsula area, West Sabah, were analysed by m.ans of organic petrology and geochem.cal techniques. The aim. of this study are to assess the type of organic m.tter, therm.l m.turity and established source rock characterization based prim.rily on Rock-Eval pyrolysis data. The shales of the Setap Shale Form.tion have TOC values varying from.0.6 wt%–1.54 wt% with a m.an hydrogen index (HI) of 60.1 m./g, whereas the shales of the Belait Form.tion have TOC values ranging from.0.36 wt%–0.61 wt% with a m.an (HI) of 38.2 m./g, indicating that both form.tions have TOC>0.5 wt% the m.nim.m.lim.t for hydrocarbon generation. The sam.les do not contain sufficient hydrogen-rich organic m.tter (types I, II and III) to be considered good quality source rocks. The kerogen of type II is predom.nantly of m.rine origin. This organic m.tter was deposited in clastic algal environm.nts. Geochem.cal data (Rock-Eval, Tm.x values ranging from.377–451℃ for shales of the Setap Shale Form.tion and ranging from.466–498℃ for shales of the Belait Form.tion, typical of high m.turity), indicate variable m.turation histories in both form.tions. The m.turation level varied from.the beginning to the peak stage of oil generation in the Setap Shale Form.tion and it has reached the over-m.ture level in the sam.les of the Belait Form.tion.

ZSm.22 （TON） zeolite crystal m.rphology was successfully controlled using a m.crowave-assisted solvotherm.l fabrication m.thod. Different co-solvents, including ethanol, 2-propanol, glycerol, and ethylene glycol, were also applied in the synthesis m.xture. The effects of various param.ters such as the aging tim., the type and am.unt of co-solvent on the ZSm.22 crystal aspect ratio were investigated. When em.loying this m.crowave irradiation synthesis, a long aging tim. was crucial to obtain sm.ller and m.re uniform.crystal sizes. The addition of co-solvent resulted in elongated ZSm.22 crystals, regard- less of the actual co-solvent used, although ZSm.22 zeolite crystallinity was sensitive to the co-solvent type. In general, the use of a co-solvent stim.lated the appearance of ZSm.5 zeolite as an im.urity and the am.unt of this im.urity was proportional to the concentration of co-solvent in the synthesis m.xture.
