Abstract: A method for preparation of a self-cleaning coating solution is provided. The method comprises mixing an aluminium compound with a solution of an ethanol compound to form a solution. Further, the formed solution is subjected to a first magnetic stirring. After the first magnetic stirring a first transparent solution is formed. Further, a stabilizing agent is added to the first transparent solution of the aluminium compound and the ethanol compound. Subsequent to adding the stabilizing agent a translucent solution is formed. Finally, the formed translucent solution is subjected to a second magnetic stirring for forming a homogeneous second transparent solution. The formed second transparent solution is a coating solution.

Abstract: Anion-exchange membranes are useful for electro-membrane processes such as electrodialysis (water desalination, separation of inorganics from organic molecules, separation of specific inorganic ion, etc.), in-situ ion-exchange and ion substitution, electro-deionization for producing ultrapure water, polymer electrolyte membrane for alkaline fuel cell and electrolysis applications. The present invention discloses an acid and base resistant fluorinated hydrocarbon based anion-exchange membrane and its method of preparation thereof. In the first step co-polymerization is carried out between N-isopropylacrylamide and 1-vinylimidazole. In the second step, obtained inter-polymer of isopropylacrylamide-co-vinylimidazole co-polymer is mixed with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) (IA-co-VI/PVDF-co-HFP), which is used for casting membrane film of desired thickness. The obtained casted membrane thin film is quaternized in methyl iodide solution.

Abstract: The present disclosure relates to a process for decomposition of sulfuric acid, particularly a process for catalytically decomposing sulfuric acid, to obtain sulfur dioxide therefrom. In the present process, catalysts play a major role for improving the dissociation efficiency by lowering the activation energy barrier for the reaction.

Abstract: The present disclosure relates to a catalyst composition for conversion of sulphur trioxide to sulphur dioxide and oxygen comprising an active material selected from the group consisting of transitional metal oxide, mixed transitional metal oxide, and combinations thereof; and a support material selected from the group consisting of silica, titania, zirconia, carbides, and combinations thereof. The subject matter also relates to a process for the preparation of the catalyst composition for conversion of sulphur trioxide to sulphur dioxide and oxygen.

Abstract: A feedwell system for delivering a slurry (for example a bituminous slurry) to a separation vessel (for example a primary separation vessel) includes a feedwell barrel with an inlet for receiving the slurry, internal baffles, and a bottom outlet. A downpipe extends from the bottom of the barrel directing the existing slurry onto a deflector plate deflecting the slurry radially and outwardly. A protector plate located between the downpipe and the deflector plate improves the underwash layer stability. Ventilation openings in the protector plate induce inflow which reduces the discharge velocity, limits the formation of an adverse pressure gradient and encourages circumferential distribution.

Abstract: An electrical power distribution system having geographically separated plural generation stations and geographically separated loads is improved by dynamically offsetting a nominal real power operating point of a main control system driving a power control element that variably feeds electrical power onto a network of transmission lines between the stations and the loads in response to deviations in frequency and/or phase of alternating current power on the network. The generation station can include an actuator control circuit for driving the control element in response to a power setting signal, the actuator control circuit incorporating a delay component, an offset signal connection downstream of the actuator control circuit bypassing the delay component. Preferably the system further includes means for monitoring a threshold level of the deviations, and means for inhibiting the means for dynamically offsetting until the deviations exceed the threshold level.

Abstract: Subsynchronous resonance is detected in an electric a.c. power supply system by determining changes in wave parameters of substantially successive half cycles and applying said changes as a relationship of said subsynchronous resonance. The parameter change measured is the wave period, and changes in the ratio of the difference of the period of positive and period of negative half cycles over the sum of the period positive and the period of negative half cycles is related to detection of subsynchronous resonance.
