Abstract: The disclosure provides a method of operating a duty-free retail operation at an airport. The airport includes a secure zone and a non-secure zone, which are separated for passengers by a security checkpoint. The duty-free store may be located in the non-secure zone of the airport. The airport may also include a product storage area and a product pickup area, which can be accessible from the duty-free store or remote from the duty-free store. The product storage area may store copies of the products displayed in the duty-free store. A passenger customer can purchase products displayed in the duty-free store, for example, by scanning QR codes associated with products and making a payment using a mobile computing device. Copies of purchased products may then be retrieved from the product storage area and delivered to a designated product pickup area before the customer boards the plane.

Abstract: A volatile copper aminoalkoxide complex of formula (I) can form a copper thin film having an improved quality by metal organic chemical vapor deposition (MOCVD): wherein, R1, R2, R3 and R4 are each independently C1-4 alkyl optionally carrying one or more fluorine substituents; and m is an integer in the range of 1 to 3.

Abstract: An aluminum oxide film is formed on a substrate by a process comprising A) bringing the vapor of a dialkylaluminum alkoxide into contact with the substrate mounted in a deposition reactor so that an aluminum-containing adsorption layer is formed on the substrate; B) removing the unreacted aluminum compound and by-products from the reactor; C) introducing an oxygen source into the reactor so that the oxygen source reacts with the aluminum-containing adsorption layer to form an aluminum oxide layer, and D) removing the unreacted oxygen source and by-products from the reactor.

Abstract: A process for coating the surface of a single crystal with a magnesium oxide film which comprises contacting an organomagnesium compound having an oxygen to magnesium atomic ratio of 1:1 with the crystal heated to a temperature ranging from 300.degree. C. to 450.degree. C. in the absence of oxygen. The magnesium oxide film thus produced has a negligible amount of residual carbon.
