Abstract: A method for manufacturing bioactive glass includes the steps below. A precursor and a polar solvent are mixed to form a mixed solution, in which the precursor includes a silicon precursor, a calcium precursor and a phosphorus precursor. The mixed solution is atomized to form a mixture droplet. The mixture droplet is oxidized in an environment of 500° C. to 900° C. to form the bioactive glass.

Abstract: A nanomaterial with a core-shell structure is provided. The nanomaterial comprises a shell and a core, wherein the shell is located on at least a portion of the surface of the core. The shell is substantially composed of a first metal oxide. The core is substantially composed of a second metal oxide, while the second metal oxide is a non-stoichiometric compound. The inventive nanomaterial exhibits excellent properties, such as good gas sensitivity and better field emission property, and has a high applicability.

Abstract: Process for thin-film electroless-plated deposition onto the substrate, which is either hydrophilic or hydrophobic silicon based dielectric material (e.g., silicon dioxide, silicate glass, or polysiloxanes), is a substitute for the conventional sensitization/activation route by pre-treating the surface of the dielectric substrate by plasma (H2/N2, N2, H2, or O2), immersing the substrate in a basic aqueous solution for removing hydrogen, immersing the substrate in a basic aqueous solution of metal ions for adsorbing the metal ions thereon, reducing the metal ions on the surface of the substrate, and immersing the substrate in an electroless-plating solution to deposit an electroless-plated metal film. The substrate formed of hydrophobic polysiloxanes which is properly pretreated by gaseous plasma can be immersed in a basic solution with strong oxidizing capability and/or performing a selective pattern by plasma treatment.
