Abstract: Embodiments of the present disclosure relate to a device having a display component that protects displayed information. In an example, a system includes a user interface of a device comprising a display module, wherein the user interface receives information entered by a user of the device. The system also includes a detector that detects surroundings around the device or the user of the device. The system further includes at least one hardware processor in communication with the user interface and the detector that automatically protects some or all of the information based on the detected surroundings and causes the automatically protected information to be displayed on the display module.

Abstract: Embodiments of the present disclosure relate to a device having a display component that displays encrypted information. In an embodiment, a system includes a user interface of a device comprising a display module, wherein the user interface receives information entered by a user of the device. The system also includes a detector that detects surroundings around the device or the user of the device. The system further includes at least one hardware processor in communication with the user interface and the detector that automatically encrypts all or portions of the information based on the detected surroundings and causes the automatically encrypted information to be displayed on the display module.

Abstract: A process for the oxidation of alkylaromatic compounds is provided. The process comprises oxidizing a substrate alkylaromatic compound with a peroxygen compound in the presence of a source of cerium (III) or (IV), a source of bromide and a carboxylic acid or anhydride solvent. Preferably, the source of cerium is cerium (III) acetate, the source of bromide is sodium bromide and the solvent is acetic or propionic acid. The process is particularly suited to the selective oxidation of methylaromatic compounds to the corresponding aldehydes.

Abstract: A process for the catalysed oxidation of ketones to esters or lactones with hydrogen peroxide in the presence of a carboxylic acid or anhydride is provided. The process employs gamma alumina as a heterogeneous catalyst. In certain preferred embodiments the catalyst also contains a tungsten-containing heteropolyacid. Preferably, the heteropolyacid contains phosphorus. In a related process, the catalyst accelerates the formation of percarboxylic acid solutions.
