Abstract: The present invention discloses a bone void filler and a method for manufacturing the same by natural calcium-containing waste, which comprises steps of mixing 5-20 wt % of a calcium-containing waste powder, 5-20 wt % of acetic acid and a remaining weight percentage of water uniformly to obtain a mixing solution; adding 5-20 vol % of a diammonium hydrogen phosphate solution to the mixing solution to obtain a suspension; controlling a pH value of the suspension to obtain an alkaline solution; leaving the alkaline solution at room temperature for precipitation for 0.1 to 72 hours, centrifuging or suction filtrating the alkaline solution to obtain a precipitate, drying and grinding the precipitate to obtain hydroxyapatite; and mixing 30-60 wt % of a pore former and 30-60 wt % of the hydroxyapatite and a remaining weight percentage of a binder uniformly to form a mixture, compression molding the mixture in a mold and sintering the compression-molded mixture.
Abstract: A digital data transmission system includes an identity-masking mechanism, a transmitter device provided with the identity-masking mechanism, and a receiver device having an identification data. The identity-masking mechanism is provided to convert a source or destination data into a source or destination identity-masking mark which is combined with a predetermined data, thereby forming a source-marked or destination-marked data with the source identity-masking mark. The source-marked or destination-marked data is transmitted from the transmitter device to the receiver device for verifying with the identification data. The receiver device cannot access the source-marked or destination-marked data if the verification is failed. The receiver device can access the source-marked or destination-marked data if the verification is passed.
Abstract: A Myrmecridium flexuosum NUK-21, a novel lactose oxidase isolated from the Myrmecridium flexuosum NUK-21 and a method for conversion of lactose into lactobionic acid (LBA) by the novel lactose oxidase are disclosed herein. The Myrmecridium flexuosum NUK-21 produces high yields of the novel lactose oxidase and the novel lactose oxidase has higher reactivity and specificity of converting lactose into lactobionic acid.
Abstract: A method for forming nanoscale microstructures by solvent etching comprises steps of preparing nanospheres and placing the nanospheres onto a surface of a liquid and allowing the nanospheres to be regularly arranged to form a template. The template is transferred to the photocurable adhesive of the substrate to form a photocured adhesive layer. After photocuring the photocurable adhesive to form a photocured adhesive layer, the substrate is removed and the template and the photocured adhesive layer are placed into a solvent with insignificant polarity to perform etching by dissolving the template with the solvent to form the nanoscale microstructure on the photocured adhesive layer. The method does not require large-scale machines, expensive equipments, and long processing time of molecular self-assembly. In addition to the above advantages, this method is not limited by size of substrates.
Abstract: A method for producing polyploid plants of orchids includes the steps of: providing a protocorm or protocom-like body (PLB) of an orchid, the protocorm or PLB having an upper portion with a growing point and a lower portion without any growing point; cutting the protocorm or PLB approximately at a point of half height to separate the upper portion; subculturing the lower portion of the protocorm or PLB in an inducing medium, and putting a cut surface of the lower portion of the protocorm or PLB to face upward so that one or more next-generation PLBs grow from the cut surface of the lower portion. The method characterized in using no antimicrotubule agent can simplify the entire process of orchid polyploidy breeding, and can be used in mass-production of the stable polyploid plants.
