    • A method for the production of nano- or microscaled ID, 2D and/or 3D depositions from an solution (6), by means of a liquid reservoir (2) for holding the ink with an outer diameter (3,D) of at least 50 nm, is proposed, wherein there is provided an electrode (7,8 or 9) in contact with said ink (6) in said capillary (2), and wherein there is a counter electrode in and/or on and/or below and/or above a substrate (15) onto which the depositions are to be produced, including the steps of: i) keeping the electrode (7, 8, 9) and the counter electrode (15, 18) on an essentially equal potential; ii) establishing a potential difference between the electrode (7, 8, 9) and the counter electrode (15, 18) leading to the growth of an ink meniscus (1) at the nozzle (3) and to the ejection of droplets (13) at this meniscus with a homogeneous size smaller than the meniscus size (11) at a homogenous ejection frequency; keeping the voltage applied while the continuously dried droplets leave behind the dispersed material which leads a structure to emerge with essentially the same diameter as a single droplet, wherein the distance between the substrate (1) and the nozzle (3) is smaller than or equal to 20 times the meniscus diameter at least at the moment of nano-droplet ejection (12); wherein the conductivity of the ink (6) is high enough to stabilize the liquid meniscus during droplet ejection;
    • 一种用于通过液体储存器(2)从溶液(6)生产纳米或微观ID,2D和/或3D沉积物的方法,用于将油墨保持至少至少具有外径(3,D) 50nm,其中提供了与所述毛细管(2)中的所述油墨(6)接触的电极(7,8或9),并且其中在和/或之上和/或下方存在对电极 和/或在其上要生成沉积物的衬底(15)上方,包括以下步骤:i)保持电极(7,8,9)和对电极(15,18)的电位基本相等; ii)建立电极(7,8,9)和相对电极(15,18)之间的电位差,导致在喷嘴(3)处生成墨水弯液面(1)和喷射液滴(13) )在均匀喷射频率下具有小于弯月面尺寸(11)的均匀尺寸的弯月面; 保持施加的电压,而连续干燥的液滴留下分散的材料,导致结构以与单个液滴基本相同的直径出现,其中基板(1)和喷嘴(3)之间的距离小于或等于 至少在纳米液滴喷射时(12)的弯液面直径的20倍; 其中所述油墨(6)的电导率足够高以在液滴喷射期间稳定所述液体弯液面;
