  • Patent number: 11970415
    Abstract: The present invention discloses a sludge anaerobic fermentation treatment method with simultaneously enhanced acid production and phosphorus removal. The method includes steps of: (1) adding waste activated sludge into an anaerobic reaction system, with a concentration of a total suspended solid (TSS) of 10000-15000 mg/L; (2) maintaining a pH value of the waste activated sludge at 10±0.1; adding powdery magnetite of 0.3-0.9 g/gVS S. Compared with simple alkaline conditions, in the method of the present invention, an accumulation amount of short chain fatty acids (SCFAs) in a fermentation broth is increased by 20%, and a content of orthophosphoric acid is reduced by 10%. The method can further improve the enhancing effect by using sulfuric acid to modify the magnetite, the accumulation amount of SCFAs can be increased by 36.7% at most, and the content of phosphorus and refractory organic substances can be reduced by 32.4% and 40.4% at most, respectively.

  • Patent number: 8475811
    Abstract: A premixed cement paste for use in medical or dental applications. The premixed cement paste remains fluid when stored in a hermetically sealed condition, but hydrates and hardens to set when placed in a physiological environment. The cement paste includes at least one calcium silicate compound and at least one substantially water-free liquid carrier mixed with the at least one calcium silicate compound; the substantially water-free liquid carrier avoids hydration of the mixture during storage, but undergoes exchange with aqueous physiological solutions so that the cement past hydrates and hardens to set when placed in a physiological environment. The paste may be placed in the physiological environment by injection, for example. The at least one calcium silicate compound may be, for example, calcium silicate, dicalcium silicate, tricalcium silicate, or mixtures thereof.

  • Patent number: 8343271
    Abstract: A hydraulic cement comprising a calcium silicate and at least one phosphate compound. The phosphate compound is included in an amount sufficient to react a major portion of the calcium hydroxide that is produced during hydration of the cement to hydroxyapatite or other calcium phosphates. The phosphate compound is preferably a mono-calcium phosphate. The cement is useful in both bio-medical/dental and engineering applications. The calcium hydroxide is reacted by the phosphate to form hydroxiapatite or other calcium phosphate that is co-precipitated with the calcium silicate hydrate to form a composite-like structure on a nano-scale level. The reduced calcium hydroxide content in the set cement increases its strength and reduces its pH. The hydroxiapatite content and the reduced pH render the cement bio-active and suitable for use in medical and dental implants, for example, for replacement bone and tooth material. Due to its high strength, the cement may also be used for structural/engineering applications.

  • Publication number: 20110003083
    Abstract: A method for forming functional ceramic films on ceramic materials, to enhance mechanical properties, chemical stability, and/or biological properties of the materials. The functional ceramic film comprises at least about 10 weight percent pure zirconia, with phase transformation at tetragonal/cubic phases at high temperature to monoclinic phase at room temperature, leading to volume expansion and compressive stress. The compressive stress enhances mechanical strength, wear resistance, hardness and other properties, and also tends to eliminate cracks and flaws in the ceramic material. The functional film may also include bioactive materials, and may include a structure for eluting drugs so as to serve as a drug delivery vehicle. The functional ceramic films may be centered on the base ceramic, or the materials may be co-centered. Devices having the ceramic materials with functional films may be used, for various medical or dental purposes.

  • Patent number: 7553362
    Abstract: A hydraulic cement for biomedical applications. The cement sets in-situ, hardening when exposed to water to produce nano-dispersed composite of calcium-silicate-hydrate gel mixed with hydroxyapatite. In comparison with prior cements, the composition provides high biocompatibility, high bioactivity and high biomechanical strength, due to the composite structure of the calcium silicate hydrate reinforced with co-precipitated particles of hydroxyapatite. Biocompatibility is also increased due to an absence of aluminum and magnesium in the composition. The cement is suitable for variety of applications, including dental implants, bone fixation, and bone repair.

The insulating layer and its aperture may be conformally coated with a conductive material that ultimately acts as a planarization stop. The conductive material may then be covered with another insulator that fills the remainder of the aperture. Thereafter, the structure may be planarized down to the conductive layer that acts as a planarization stop.
