Abstract: Novel non-linear optical, piezoelectric, pyroelectric, waveguide, and other materials are presented together with processes for their employment and articles formed thereby. Such materials, processes and articles comprise diacetylenes and polymers formed from diacetylenic species, which polymers are amenable to close geometric, steric, structural, and electronic control. Accordingly, it is now possible to design, formulate and employ new diacetylenic species and polymers formed therefrom to provide non-linear optic, waveguide, piezoelectric, and pyroelectric materials and devices having surprising efficiencies and degrees of effect. 
<??>According to a preferred embodiment of the invention, diacetylenes which are crystallizable into crystals having a non-centrosymmetric unit cell may form single crystals or may be elaborated into a thin film upon a substrate by the Langmuir-Blodgett technique. Such films may, optionally, be polymerized either thermally or by irradiation for use in non-linear optical and other systems. According to other prefered embodiments, diacetylenes are covalently bonded to substrates through the employment of silane species and subsequently polymerized to yield non-linear optic and other devices having high structural integrity in addition to high efficiencies and effects.

Abstract: A photovoltaic cell is formed by combining a spray process, forming a crystalline layer containing cadmium and sulfur, and an evaporation process, depositing copper chloride for converting to Cu x S. The crystals containing cadmium and sulfur are heated in an atmosphere of cadmium and chlorides to obtain crystals having at least one dimension greater than 0.5 micron and a planar layer of Cu x S is formed on the large crystals. A layer of Cu x S having a thickness of 0.5-1.0 micron is obtained. Electrodes are formed from evaporated gold or chromium or a metallic paste including silver or copper. Zn x Cd 1-x S may be substituted for CdS through at least part of the crystalline layer for improved Voc.

Abstract: In electron beam testing systems wherein high energy, 'high resolution electron beams 14 are used to test litho- tgraphic masks 16, a technique and apparatus is described for discharging electrons which are left on the surface of the mask. The materials used in these masks e.g. for substrate are such that induced photoconductivity and photoemissivity are extremely low and are incapable of providing sufficient eletron discharge. The electrons are discharged by using a thin, low work function (e.g. between 1 and 3eV) coating 20 which is applied over the entire mask surface, the coating 20 being transparent to the radiation which will later be incident upon the mask when it is used in a fabrication process. Due to induced photoemission in the thin coating layer, enough photoemitted electrons will be produced to balance the buildup of electrons from the electron beam, thereby discharging the surface of the mask. The electron beam is a high energy beam, having energies greater than about 5000 eV, and a resolution less than about 1 micrometer. Cesium telluride (CsTe) is a suitable coating material.

Abstract: A vaccine comprising as active ingredient living cells of a Human mutant strain of Streptococcus mutans is effective to specifically inhibit the growth of cariogenic wild strains of Streptococcus mutans and may be used for preventing or inhibiting Streptococcus mutans induced dental caries. The mutant strain is substantially deficient in cariogenic potential and may be isolated from human oral flora or may be artificially induced from cariogenic wild strains of S. mutans. The non-cariogenic mutant strain may be administered in the form of a food composition such as a drink, comprising living cells, of the mutant strain in association with a liquid carrier conventionally used for preparing drinks containing the living cells of edible lactic acid-producing bacilli. When the living cells of the non-cariogenic mutant strain of this invention and the living cells of edible lactic acid-producing bacilli are mixed, for example, in the form of yogurt, the cariogenic potentials of both the cariogenic S. mutans and the edible lactic acid-producing bacilli may be prevented or inhibited effectively.
