Special Issue Information

Dear Colleagues,

The art of nano-manipulation organically penetrates into many advanced fields of science and technology, such as nanoelectronics, nanobiology, nanophotonics, etc. In recent decades, many new nanomaterials have been discovered and new revolutionary fields of research and applications have appeared, but the handling of an individual nano-object often remains a difficult task, especially in cases where 3D nanomanipulation is needed. Despite the fact that dual-beam scanning electron/ion microscopes, usually equipped with nano-manipulation systems, are currently widespread in scientific laboratories, it takes a lot of time to select, capture, transport, and install a separate nanoscale object in a new location, especially when working with an insulator, soft matter or a biological nanoobject.

In general, we can define nano-manipulation as the art of the controlled moving of nanoobjects sized at least in one dimension less than 100 nm, or the moving of an object by a nanosized tool, or the controlled moving of an object with a precision within the nanometer range. Recent admired achievements in these fields are the design, by bottom-up nanofabrication, of semiconductor nanowire-based ultrasensitive biosensors for the direct detection of protein markers of such infections as Chagas disease or coronavirus, the bottom-up nanointegration of the first carbon nanotube computer, the demonstration of mechanical 3D nanomanipulation using nanosized thermally controlled shape memory nanotweezers, etc.

This Special Issue of Nanomaterials devoted to nanomanipulation is intended to attract researchers and engineers in a wide variety of emerging fields, including smart nanomaterial development, mechanical nanotools and nano-manipulation system design and new approaches to the study of nanomaterials and nanomanufacturing based on 3D nano-manipulation and bottom-up nanointegration. The Special Issue also hopes to attract studies on the current progress in the development of practical nanorobotic systems which have recently succeeded in the demonstration of automatic processes of 3D nano-manipulation, nanointegration and nanomanufacturing.

Recently, Ti-Ni based intermetallic alloys with shape memory effect (SME) have attracted much attention as promising functional materials for the development of record small nanomechanical tools, such as nanotweezers, for 3D manipulation of the real nano-objects. The problem of the fundamental restrictions on the minimal size of the nanomechanical device with SME for manipulation is connected with size effects which are observed in small samples of Ti-Ni based intermetallic alloys with thermoplastic structural phase transition from austenitic high symmetrical phase to low symmetrical martensitic phase. In the present work, by combining density functional theory and molecular dynamics modelling, austenite has been shown to be more stable than martensite in nanometer-sized TiNi wafers. In this case, the temperature of the martensitic transition asymptotically decreases with a decrease in the plate thickness h, and the complete suppression of the phase transition occurs for a plate with a thickness of 2 nm, which is in qualitative agreement with the experimental data. Moreover, the theoretical values obtained indicate the potential for even greater minimization of nanomechanical devices based on SME in TiNi. Full article

Despite considerable research efforts, the influence of contact line tension during wetting at the nanoscale and its experimental determination remain challenging tasks. So far, molecular dynamics simulations and atomic force microscope measurements have contributed to the understanding of these phenomena. However, a direct measurement of the size dependence of the contact angle and the magnitude of the apparent line tension has not been realized so far. Here, we show that the contact angle is indeed dependent on the drop size for small drop diameters and determine the magnitude of the apparent line tension via liquid-metal based measurements of advancing and receding contact angle inside a scanning electron microscope. For this purpose, a robotic setup inside an electron microscope chamber and oxide-free Galinstan droplets—produced via an electromigration-based and focused ion beam irradiation-assisted process—are employed. Using the first-order correction of Young’s equation, we find an apparent line tension value of 4.02 × 10−7 J/m for Galinstan© on stainless steel. Full article
