  • Hollow microneedle array
    Publication number: 20070023386
    Abstract: An inexpensive and rapid method for fabricating arrays of hollow microneedles uses a photoetchable glass. Furthermore, the glass hollow microneedle array can be used to form a negative mold for replicating microneedles in biocompatible polymers or metals. These microneedle arrays can be used to extract fluids from plants or animals. Glucose transport through these hollow microneedles arrays has been found to be orders of magnitude more rapid than natural diffusion.

  • Crystalline aluminosilicate percursor
    Patent number: 4160011
    Abstract: An amorphous powder useful as a precursor for the preparation of crystalline aluminosilicates is prepared by forming a sodium aluminum silicate water mixture whose composition falls within specified ranges for forming sodium zeolite A. By dehydrating the mixture with a water miscible solvent prior to aging and crystal formation, an amorphous powder is recovered for future use. Upon subsequent treatment the amorphous powder can be converted to crystalline aluminosilicates including type 3A, 4A, 5A, X and Y.

  • Method of preparing a reaction chamber
    Patent number: 4108218
    Abstract: A novel reaction chamber includes a gravity-packed bed formed of an attenuated support medium bearing solidified fused-solid whereby the bed is formed into a matrix which is particularly useful as a catalytic conversion chamber, a muffler, etc.
