The present specification provides a NOx responsive element suitable for directly sensing NOx. The NOx responsive element an oxygen ion conductive layer has a first electrode layer having a nitrogen oxide decomposition catalyst phase composed of perovskite-type oxide, being in contact with the oxygen ion conductive layer, and being exposed to NOx, and a second electrode layer opposing the first electrode layer across the oxygen ion conductive layer. The nitrogen oxide decomposition catalyst phase has a nitrogen oxide adsorption stabilizing surface on its surface exposed to nitrogen oxide.

Nitrogen oxide responsive element and method for producing same

Artificial marble is produced by laminating a plurality of prepreg sheets formed by impregnating a porous substrate with a melamine resin composition which is composed of melamine resin and a modifier. The melamine resin is an unmodified melamine resin or an alcohol-etherified melamine resin in which formaldehyde-to-melamine molar ratio is between 1.2 to 3.0. The modifier is selected from alcohol, glycol, acrylic monomer, acrylic oligomer and vinyl acetate monomer. The artificial marble has a good stability in dimensions and it is suitable to apply the artificial marble to a composite panel or a decorative laminate panel which is free from tearing even after long time use.
