Existing transfer technologies in the construction of film-based electronics and devices are deeply established in the framework of native solid substrates. Here, we report a capillary approach that enables a fast, robust, and reliable transfer of soft films from liquid in a defect-free manner. This capillary transfer is underpinned by the transfer front of dynamic contact among receiver substrate, liquid, and film, and can be well controlled by a selectable motion direction of receiver substrates at a high speed. We demonstrate in extensive experiments, together with theoretical models and computational analysis, the robust capabilities of the capillary transfer using a versatile set of soft films with a broad material diversity of both film and liquid, surface-wetting properties, and complex geometric patterns of soft films onto various solid substrates in a deterministic manner.

The wettability of clay roofing tiles as a surface phenomenon plays a key role considering their deterioration process during exploitation. The experimental investigations in this paper were performed combining the data of the material-relevant parameters and the surface wetting properties in order to assess clay roofing tiles biodurability. The fungus Aspergillusniger was used as a model microorganism whose colonization and growth, during a period of 28 days on the tiles fired at two temperatures (900 and 1020?C), was analyzed. The paper confirms that the colonization of the tiles with the fungus goes through two stages: up to the 18th day, based on the surface characteristics, and after the 18th day when the textural characteristics (values of water absorption) are the dominant parameters.

The influence of the surface properties of different solid materials on the process of blood flowing through them is analyzed. Based on the dependence of the blood coagulation rate on the wetting properties of the solid surfaces on which it spreads, the urgency of developing an express method of controlling the process of blood wetting of the artificial vessels surfaces to prevent thrombosis is substantiated. The adhesion work which is consumed of blood drainage is determined. The impedance method was developed, which is based on the relationship between the flow rate and the change in impedance The impedance method was developed, which is based on the relationship between the flow rate and the change in impedance of the flat capacitor, between the plates of which is the investigated system blood – implant. The interelectrode space of the cell (the investigated system) can be considered as a heterogeneous dielectric, which is a collection of blood, air, and implant samples. Each of these layers can be represented by a set of capacitors and resistors in parallel and connected in series. In the course of blood drainage on the inclined surface of the test sample of implant material, which is located on the bottom plate of the condenser, the redistribution of blood layers, air and sample of the implant occurs, that is, the dielectric constant of the electrode medium changes. The design of the device implementing the impedance method and the results of laboratory tests are presented. Graphic dependencies for establishing the wetting degree of blood the most used materials in the creation of artificial vessels, which confirmed the need for special coatings to increase the blood coagulation time.
