“…First of all, the Kikuchi patterns obtained by the electron backscatter diffraction (EBSD) of the individual NWs taken at different positions of the sample showed that they are single crystalline and have the same crystallographic orientation, even azimuthally [47,48]. Further, the obtained nanostructures exhibit extremely high aspect ratios (>1000) [46], unreachable by most other techniques. It is important to emphasize that the wire length can be easily controlled by the etching duration [49].…”

“…For larger structures such as nanowires of Re or W formed from directional solidification of a eutectic alloy it was possible to isolate single wires with diameters of down to 100 nm [29][30][31]. For preparing isolated Au nanostructures from the processed material a selective dissolution process must be employed that allows a simultaneous stabilisation of the Au nanoparticles and to prevent irreversible coagulation of these particles.…”

“…Исследования фазообразования в тройной системе Ni-Al-W [1,2] показали, что эвтектические сплавы NiAl-W могут использоваться в качестве основы для по-лучения NiAl нанопористых фольг, вольфрамовых на-норазмерных нитей и проволок [3 -6]. Метод направ-ленной кристаллизации Бриджмена для получения эвтектических сплавов NiAl-W с последующим электро-химическим селективным вытравливанием либо воль-фрамовых монокристаллических нанонитей, либо ин-терметаллидной матрицы применялся в работах [1 -6].…”
