  • METHODS OF FORMING ARTICLES HAVING SPINEL-BASED OXIDES CONTAINING MAGNESIUM, ALUMINUM AND TITANIUM
    Publication number: 20240124361
    Abstract: The disclosed technology generally relates dielectric materials and methods of forming the same, and more particularly to a combination of co-fireable dielectric materials that can be attached to each other without the use of adhesives. In an aspect, a composite article comprises a magnetic portion comprising a nickel zinc ferrite. The composite article additionally comprises a non-magnetic portion contacting the magnetic portion, the non-magnetic portion comprising a spinel-structured oxide comprising Mg2-xAl2xTi1-xO4 and having a dielectric constant between about 7 and 14, wherein 0<x?1.

  • Recovery of lignin and water soluble sugars from plant materials
    Patent number: 8822657
    Abstract: In one aspect, a process for treating woody plant material is provided, the process involving contacting the plant material with a continuous flow of an aqueous ethanol solution at elevated temperature and pressure under conditions that promote extraction of ethanol-soluble lignin from the plant material and retention of hemicellulose sugars, xylose and cellulose in the treated plant material solids. In another aspect, a process for extracting hemicellulose sugars from lignin-depleted plant material solids is provided, the process involving contacting lignin-depleted plant material with water at elevated temperature and pressure under conditions that promote extraction of hemicellulose sugars from the plant material; and recovering hemicellulose sugars from the liquid mixture.
