Abstract: A method of manufacturing a water-soluble transfer stack comprising multilayer two-dimensional material includes: i. Providing a growth stack comprising a growth substrate and a two-dimensional material layer; ii. Applying an intercalating solution, to the growth stack; iii. Applying a transfer layer comprising a water-soluble polymer film, to the growth stack; iv. Delaminating the water-soluble polymer film together with the two-dimensional material layer, thereby obtaining a delaminated film, from the growth substrate; and v. Repeating steps i.-iv. a number of times, wherein the delaminated film is used as the transfer layer; thereby manufacturing a water-soluble transfer stack comprising multilayer two-dimensional material.

Abstract: The present disclosure relates to a holder for a test object, more specifically to a holder for measuring electrochemical properties of the test object.

Abstract: The present application discloses a method for separating a graphene-support layer laminate from a conducting substrate-graphene-support layer laminate, using a gentle, controllable electrochemical method. In this way, substrates which are fragile, expensive or difficult to manufacture can be used—and even re-used—without damage or destruction of the substrate or the graphene.

Abstract: One or more digital representations of single- (101) and/or few-layer (102) thin-film material are automatically identified robustly and reliably in a digital image (100), the digital image (100) having a predetermined number of color components, by—determining (304) a background color component of the digital image (100) for each color component, and—determining or estimating (306) a color component of thin-film material to be identified in the digital image (100) for each color component by obtaining a pre-determined contrast value (CR; CG; CB) for each color component and multiplying the respective background color component with a numerical difference between the pre-determined contrast value (CR; CG; CB) for a given color component and about 1,—identifying points or parts of the image with all color components being within a predetermined range of the determined or estimated color component.

Abstract: A method of making an article 2 comprising an ultra-thin sheet 26 of material secured at lateral regions to a support member, the method comprises laying the ultra-thin sheet on a substrate 20, forming the support member on the lateral regions of the ultra-thin sheet such that the lateral regions of the ultra-thin sheet are sandwiched between the support member and the substrate and adhered to the support member, and removing the substrate by vaporisation or by a dissolution step using a solvent, to leave the article. The ultra-thin sheet is supported around its periphery and has a central region in which the ultra-thin sheet is free from contact with any other material.
