Abstract: The invention describes a set of cooking utensils for steaming food, essentially a casserole or main part and another casserole or secondary part which is inserted into the main part, with the novelty that the secondary part remains suspended on some notches provided on the inner walls or sides of the main part. With this system of engagement, the secondary part can have a smaller size than in traditional designs, thereby reducing the cost and the complexity of its manufacturing and simplifying its cleaning and storage.

Abstract: A chemical vapor deposition process for the in-situ preparation of conformal copper-doped aluminum coatings on a substrate comprises the steps of generating a first flow of a first reactant vapor directed to the substrate in the reactor, the first reactant vapor including a copper source precursor; heating the substrate to a temperature sufficient to decompose the first reactant vapor and form an ultrathin copper seed layer; generating a second flow of a second reactant vapor directed to the substrate in the reactor, the second reactant vapor including an aluminum source precursor; and heating the substrate to a temperature higher than 185° C. to decompose the second reactant vapor and form a copper-doped aluminum film.
