The combination of porosity parameters that allows mesoporous silicates to be competitive with organoclays for the reinforcement of engineering polymers include an average mesopore size of at least 2 nm, a surface are of more than about 50 square meters per gram, a total pore volume of more than about 0.33 cubic centimeters per gram, wherein at least 20% of the total pore volume is due to mesopores about 2 to about 50 nm.

Abstract: The object of this invention is to provide a hybrid composite journal bearing which is constructed so that a composite liner is positioned on an inner surface of a metal housing having a circular cross-section, thus preventing a journal from being broken or damaged or seized to the bearing, due to friction between the metal or composite journal and the journal bearing. The hybrid composite journal bearing (210) includes a metal housing (211) which is secured on an outer surface thereof to a bearing system and has a circular cross-section. A composite liner (212) is laminated to an inner surface of the metal housing (211) with a uniform thickness so as to minimize friction between the journal bearing and a journal.

Abstract: In a metal membrane for a low-temperature-fluid storage tank wherein longitudinal and transverse corrugations are formed and both corrugations intersect each other, a bidirectional expandable member connected to each corrugation is formed in the intersection of the corrugations so that the bidirectional expandable member is longitudinally and transversely expandable. The bidirectional expandable member is protruded and is shaped like a pyramid, a dome or a cross. Each metal membrane is welded into a unit panel and the edge of each metal membrane is welded with the common edge of another adjacent metal membrane.

Abstract: A process is described for the synthesis of metal oxides in a nanometric particle form that cannot be easily obtained by conventional bulk synthesis techniques. The method makes use of Colloid Occluded Carbons (COC) and Colloid Imprinted Carbons (CIC) as reagents and as templating agents for the preparation of metal oxides in nanometric particle form. The nanometric particles are suitable useful in the field of chemical catalysis, particularly for petroleum refining when in porous form, and as sensors, optical wave guides, and coatings.
