Abstract: The present disclosure discloses a method and an apparatus for displaying online transaction information. The method includes: displaying a first transaction information page on a terminal; sending first order information based on the first transaction information display page by a terminal to a server; sending first payment information by a server to the terminal in response to the first order information; and displaying a second transaction information display page including the first order information and the first payment information. The first order information is modifiable on the first and the second transaction information display page. The first payment information includes a plurality of payment platform identifiers from which a user can select to complete the online transaction.

Abstract: The present disclosure discloses a method, a device, and a system for updating authenticating information in the field of Internet technologies. The method comprises: receiving a service processing request containing user information and service object information; extracting according to the user information, first authentication information associated with the service object information from prestored authentication information; authenticating the first authentication information; displaying an information update interface when the first authentication information fails to be authenticated; obtaining second authentication information from the information update interface; replacing the first authentication information with the second authentication information; authenticating the second authentication information; and processing the service processing request if the second authentication information is authenticated.

Abstract: The present invention relates to semiconductor materials that include a silicon-based quantum dot; and a conjugated organic ligand connected to the silicon-based quantum dot to obtain a functionalized quantum dot. An additional aspect of the present invention is to provide methods that include providing a silicon-based quantum dot; and connecting a conjugated organic ligand connected to the silicon-based quantum dot to obtain a functionalized quantum dot.

Abstract: A kind of ascorbic acid derivates 3-O-glyco-L-ascorbic acid, their preparation methods, intermediates and uses in cosmetics. The derivates used as vitamin C precursors have better physiological effect than 2-O-?-D-glucopyranosyl ascorbic acid (AA-2G) and are more stable. Present compounds can be used in many fields, such as in cosmetics, pharmaceuticals, foodstuffs and livestock feed, and especially as whitening agents in cosmetics. The preparation method involves protecting the 5,6-dihydroxyl of ascorbic acid, then coupling with 1-haloacylglycosyl, obtaining the intermediate 3-O-(acylglycosyl)-(5,6-O-isopropylidine)-L-ascorbic acid, removing the isopropylidine and acyl from the intermediates, thereby obtaining the target substance.
