A novel inorganic hollow fiber membrane reactor (iHFMR) has been developed and applied to the catalytic dehydrogenation of propane to propene. Alumina hollow fiber substrates, prepared by a phase inversion/sintering method, possess a unique asymmetric structure that can be characterized by a very porous inner surface from which finger-like voids extend across $80% of the fiber cross-section with the remaining 20% consisting of a denser sponge-like outer layer. In contrast to other existing Pd/Ag composite membranes, where an intermediate c-Al 2 O 3 layer is often used to bridge the Pd/ Ag layer and the substrate, the Pd/Ag composite membrane prepared in this study was achieved by coating the Pd/Ag layer directly onto the outer surface of the asymmetric substrate. After depositing submicron-sized Pt (0.5 wt %)/c-alumina catalysts in the finger-like voids of the substrates, a highly compact multifunctional iHFMR was developed. Propane conversion as high as 42% was achieved at the initial stage of the reaction at 723 K. In addition, the space-time yields of the iHFMR were $60 times higher than that of a fixed bed reactor, demonstrating advantages of using iHFMR for dehydrogenation reactions. V

Medicinal plant derived compound have an important role in the development of many clinically useful agents. Catharanthus roseus is a significant medicinal plant of the Apocynaceae family. Catharanthus roseus plant is used for different disease treatment such as skin cancer, Hodgkin's disease, breast cancer, and lymphoblastic leukemia. The aim of this study is conferring the comparative abundances of different phytochemicals, physiochemical and fluorescence analysis from Catharanthus roseus. Some of the chemical constituent's tests have been performed for phytochemical analysis. Fluorescence analysis was done by using dried powder mixed with different chemicals and have been observed under UV light (365 nm) and ordinary light. Total ash, acid insoluble ash, and moisture have been selected for physiochemical analysis. The precipitate formation or colour change was used as analytical answers for phytochemical analysis. The result of fluorescence analysis observed under UV light (365nm) and ordinary light by observing colour changes in sample. The percentage of loss of weight on drying, total ash and acid insoluble ash were obtained by employing standard methods of analysis for the physiochemical test. Extraction of Catharanthus roseus plant using deep eutectic solvent gave positive results.

Polyvinylidene fluoride-co-polytetrafluoroethylene, PVDF-co-PTFE polymer was used as a membrane support. The asymmetric membranes were formed by immersion of casted membrane film into the coagulation bath. This work manipulated the coagulant bath medium by mixing ethanol with distilled water at different weight percentages (0, 25 and 50 wt. % of ethanol). The structures of fabricated membranes were observed to have different morphologies. Higher ethanol content altered the membrane structure from finger-like to sponge-like structure, and hence differed in membrane porosity. Vacuum-based technique was chosen to impregnate the deep eutectic solvent (DES) into the pores of membrane support. DES was prepared by mixing choline chloride (ChCl) and ethylene glycol at a ratio of 1:3. Scanning electron microscopy (SEM) was used to study the membrane morphology changes while in order to determine the immobilization of DES, energy dispersive X-ray (EDX) analysis was used. The porosity of fabricated PVDF-co-PTFE membrane was determined by means of gravimetric method. Lastly, the membrane separation performance using CO2 and N2 gasses were used to determine the capability of the supported-DES-membrane.  The results demonstrated the highest immobilization of DES in supported membrane pores was achieved when combination of 25 wt. % of ethanol and 75 wt. % distilled water was used as a coagulant bath medium. The respective membrane has 74.5% porosity with the most excellent performance of CO2 separation at 25.5 x 103 GPU with CO2/N2 selectivity of 2.89.
