The present invention is directed to rigid filtration apparatus comprising a filter support and filter membrane. Such filter support is comprised of a central core. Radiating from the central core are a plurality of pleats composed of two angled walls terminating at a contact point. Such longitudinal walls circumscribe a longitudinal channel situated between the walls wherein the longitudinal channel is in communication with the central core. The longitudinal walls are comprised of a plurality of openings along the walls. A filter membrane having biocidal components may be utilized with the filter support to effectively treat contaminated fluid, gas or air. Alternatively, the composition of the rigid central core and the rigid pleats may be composed of different materials to selectively remove chemicals, biological components or pharmaceuticals in a multi-stage treatment process.

A process for use of composite catalysts for oxidation of amines during synthesis of energetic compounds. This method overcomes the safety concerns associated with dangerous reaction conditions for these energetic materials. The process requires exposing phthalocyanine conjugated to an inorganic substrate to the precursor reactant and activating the composite material to light and oxygen to covert amine groups into oxidized nitrogen species.

A method of purifying or sanitizing contaminated water to be potable, by exposing the water in the presence of light, to an electrically neutral metal complex of a perfluoroalkylated fluorinated phthalocyanine photosensitizer, having only external R groups with C&#x2014;F bonds, preferably FPcZn; whereby, a sufficient quantity of singlet oxygen is provided by the chemical reaction of the light and the photosensitizer to destroy the pollutants or pathogens present in the contaminated water.

A reticle which does not emit a retro-reflective signature detectable using standard field detection means at the standard distance of 10 miles, which reticle is formed of a precise series of about 10 micron wide lines etched within a physically light weight, single optical blank or glass lens, using a femtosecond near IR wavelength pulsed laser.
