Abstract: A dual fumigation homogeneous charge compression ignition (DF-HCCI) engine runs on low volatility internal combustion (IC) engine fuel such as diesel in combination with another IC engine fuel, both simultaneously fumigated in engine intake air stream. Both fumigated fuels mix with engine intake air and they are inducted together, at the same time, into engine combustion chamber where homogeneous charge compression ignition combustion takes place. Fumigation of two fuels, in which one fuel has low volatility, is done by a novel dual fuel fumigation system comprising of at least one ultrasonic atomizer. Combustion phasing control is done by varying proportions of fumigated fuels, EGR rate, and EGR temperature and additionally by controlling engine intake air temperature. Engine intake air is controlled to a desirable temperature by heat exchanger utilizing heat from engine and/or exhaust gas.

Abstract: We claim a simple strategy for the synthesis of a collection of C(3?)-spirodihydroisobenzo-furannulated and C(3?)-spirodihydroisobenzo-furannulated nucleosides featuring a [2+2+2]-cyclotrimerization as the key reaction. The cyclotrimerization reactions are facile with the unprotected nucleosides having a diyne unit. When both alkynes of the diyne are terminal, the regioselectivity is poor. However, when one of the terminal alkynes is additionally substituted, the cyclotrimerizations are highly diastereoselective. Since the key bicycloannulation is the final step, this strategy provides flexibility in terms of the alkynes and is thus amenable for the synthesis of a focussed small molecule library.

Abstract: Semiconductor-oxide nanotubes-based composite particles are useful for dye-removal. A method involves an ion-exchange mechanism operating under a dark-condition in an aqueous solution, for the processing of products consisting of the nanotubes of semiconductor-oxides deposited on, anchored to or attached to the surface of fly ash particles and metal-oxide (magnetic and non-magnetic) nanoparticles. The resulting micro-nano and nano-nano integrated composite particles can be used in the removal of an organic synthetic-dye from an aqueous solution and industry effluent via a surface-adsorption process, involving ion-exchange and electrostatic-attraction mechanisms. The composite particles can be recycled for the next cycle of dye-adsorption by decomposing the previously adsorbed dye on their surfaces via the use of either noble-metal-deposited or magnetically separable magnetic photocatalysts and exposure to ultraviolet (UV) or solar-radiation.
