Abstract: A catalyst adapted for generating hydrogen peroxide induced by a temperature difference and a method for environmental disinfection using the same are provided. The catalyst includes a thermoelectric material distributed on a substrate. The thermoelectric material induces a reaction between water vapor and oxygen contained in the air through a temperature difference to generate hydrogen peroxide, to serve a sterilization function through the hydrogen peroxide generated. The method for environmental disinfection using the catalyst includes the following. The catalyst is placed in an environment with a temperature difference. The catalyst is caused to induce a reaction between water vapor and oxygen contained in air through the temperature difference to generate hydrogen peroxide without applying power, and serve a sterilization function through the hydrogen peroxide generated.

Abstract: Methods of etching a plurality of glass-based sheets comprise sorting a plurality glass-based sheets into a plurality of groups based on an average sheet thickness of a corresponding glass-based sheet. A maximum difference between a first average sheet thickness of a first sheet and a second average sheet thickness of a second sheet of a first group of the plurality of groups is less than or equal to a predefined threshold. Methods can further comprise sorting the first group into a plurality of sub-groups based on a total thickness variation. Methods of etching a glass-based sheet comprise placing the glass-based sheet in a jig, where a second edge is closer to the perimeter support than the first edge is to the perimeter support. Methods of etching a glass-based sheet comprise placing the glass-based sheet in a jig, where a first edge is closest to a top side of the jig.
