Abstract: A method of cleaning equipment such as heat exchangers, evaporators, tanks and other industrial equipment using clean-in-place procedures and a pre-treatment solution prior to the conventional CIP cleaning process. The pre-treatment step improves the degree of softening of the soil, and thus facilitates its removal. The pre-treatment solution can be a strong acidic solution, a strong alkaline solution, or comprise a penetrant. A preferred strong acidic solution is an acid peroxide solution. In some embodiments, the pre-treatment may include no strong alkali or acid ingredient; rather, the penetrant provides acceptable levels of pre-treatment.
Abstract: A method and composition for removing bulk and ion-implanted photoresist and/or post-etch residue material from densely patterned microelectronic devices is described. The composition includes a co-solvent, a chelating agent, optionally an ion pairing reagent, and optionally a surfactant. The composition may further include dense fluid. The compositions effectively remove the photoresist and/or post-etch residue material from the microelectronic device without substantially over-etching the underlying silicon-containing layer(s) and metallic interconnect materials.

Abstract: The production of bleaching agent granulates, wherein a particulate peroxide compound and a water soluble polymer which can be ionotropically cross-linked are granulated into a primary granulate using a liquid binding agent containing water, and the primary granulate is brought into contact with a cross-linking agent for the water soluble polymer which can be ionotropically cross-linked. A particle so obtained can be worked into liquid detergents and cleaning agents containing water and remain stable.

Abstract: A series of crosslinkable sulfonated poly(ether ketone)s containing cycloalkenyl groups were synthesized by aromatic nucleophilic substitution reaction. To decrease the swelling of fuel cell membranes, crosslinking of theses polymers by radical polymerization has been explored. These polymeric films exhibit good thermal and oxidative stability, and good dimensional stability in hot water. The proton conductivity of one example at room temperature is 7.52*10?2 S/cm. The results showed that these materials containing cycloalkenyl groups are possible inexpensive candidate materials for proton exchange membranes in fuel cell applications.
