    摘要： Provided with a novel ascorbic acid derivative represented by the formula (I) and a method for preparing the same: wherein R1 and R2 are different from each other and, independently H or —CH2CH2—(O—CH2—CH2)n—OR3, wherein n is an integer from 2 to 400; and R3 is a lower alkyl group having 1 to 10 carbon atoms. The novel ascorbic acid derivatives of this invention have excellent characteristics such as long-lasting anti-oxidation effect, high solubility in both water and organic solvents, and high stability in an aqueous solution. Furthermore, the novel ascorbic acid derivatives are useful for feed, food, cosmetic and pharmaceutical products due to their low toxicity and high thermal stability.

    摘要： A process for making a magnetic head including the steps of forming a first pole piece comprising magnetic material and depositing a gap-forming layer comprising nonmagnetic material over the first pole piece. A first patterned layer of uncrosslinked polymer is formed on the gap-forming layer. The first patterned layer is cured by electron irradiation at a temperature less than about 175 C. to crosslink the polymer. A conductive coil is formed on the cured first patterned layer and a second patterned layer of uncrosslinked polymer is formed over the conductive coil. The second patterned layer is cured by electron irradiation at a temperature less than about 175 C. to crosslink the polymer. A second pole piece layer of magnetic material is formed to complete the magnetic head.

    摘要： The present invention relates to a magnetic nanoparticle having a Curie temperature which is within a biocompatible temperature range, a method for preparing same, and a nanocomposite and a target substance detection composition comprising the magnetic nanoparticle. As the magnetic nanoparticle of the present invention has a Curie temperature within the temperature range of 0 degrees centigrade to 41 degrees centigrade, the ferromagnetic and paramagnetic properties of the magnetic nanoparticle may be controlled within a biocompatible temperature range at a temperature at which a biological control agent is not destroyed, and the temperature of the magnetic nanoparticle is adjusted to control the magnetic properties thereof such that the properties of the magnetic nanoparticle may be used only when ferromagnetic properties are required, such as in the case of signal amplification in detecting, separating, and delivering biological control agents. Accordingly, the magnetic nanoparticle of the present invention can minimize adverse effects of ferromagnetic properties thereof, and can be used in the effective detection and separation of biological control agents.
