Preparation method of one-dimensional scale limited graphene nano band

The invention discloses a preparation method of a one-dimensional scale limited graphene nano band, which comprises the steps of: providing a transition metal substrate; coating photoresist on the surface of the transition metal substrate to form a photoresist layer; transferring a defined pattern to the photoresist layer through exposure development to form a photoresist graph; with the photoresist layer as a mask, carrying out carbon ion injection in the transition metal substrate to form a carbon ion injection region; figuring out an injection angle for the carbon ion injection according to the graphene width in combination with the thickness of the mask of the photoresist layer and the width of the photoresist graph; and removing the photoresist layer; and carrying out thermal annealing, separating carbon atoms from the carbon ion injection region for reconstruction, and forming the one-dimensional scale limited graphene nano band with a width of close to even less than 10nm on the surface of the transition metal substrate. Compared with the prior art, the preparation method is used for preparing the graphene nano band by carrying out carbon ion injection at a calculated specific injection angle, and has the advantages of accuracy in preparation, simple preparation process and high yield.

Digital method for matching stains

The present invention relates to color matching and, more specifically, an apparatus and method for preparing a stain to match a target color of a selected substrate (e.g., wood species). In one embodiment a system is provided that comprises (i) a computer (e.g., a stand-alone PC or a networked computer), (ii) hardware and / or software to store a database of stain records, (iii) hardware and / or software to create or load spectral data (e.g., a digital image) of a target sample, and (iv) hardware and / or software to display images and / or process spectral data. The system preferably facilitates the selection of a desired stain, and in preferred embodiments may also include hardware and / or software to dispense colorant agents and / or vehicles to create the desired stain. The system of the present invention may be used in a “manual” mode (whereby a human compares database and target images and makes a selection); an “automatic” mode (whereby the computer system uses spectral data to suggest a closest match based on the selected substrate); or a “combination” mode (whereby the computer system uses spectral data to suggest a closest match and the user can then compare the suggested match with various images to achieve a final selection).

Method, cartridge and apparatus for mixing beverages

A method for semi-automatic preparation of a range of standard cocktails and/or long drinks, wherein each cocktail is a mixture of liquid and/or creamy base components, dosed according to official international standards, said method comprising at least the steps of a) providing a plurality of empty stackable capsules (2), b) filling each capsule (2) with one or more standardized doses (D) of individual base components (B) of the cocktail to be prepared, c) sealing said capsules (2) with frangible walls (3, 4) d) arranging said filled capsules (2) one on top of the other to form a stack (5), e) sequentially piercing said capsules (2) to cause the base components (B) contained therein to flow out, f) collecting the base components (B) of all the capsules into a single receptacle (6), g) mixing the base components (B) collected in said receptacle (6) to obtain the cocktail, h) transferring the cocktail into a container for consumption by a user. The empty capsules (2) have identical plan shapes and different heights (h1-5), to define a limited number of capsule sizes (M1-5) having different volumes (V1-5), each capsule size (M1-5) being dimensioned to contain a unit dose (D) of a base component of predetermined value, for preparing all the cocktails of the range, in combination with the other capsules (2) of the stack (5).
