“…The sessile-drop method was used for CA measurements of doubly distilled water droplets of 5 μl under ambient conditions. The CA was calculated automatically after stabilization for 60 s of the deposited drop on the foil surface using a specially designed program "Angle" [15]. The results of water CA tests were determined as averages of the values measured at 5 different spots for each foil composition.…”

The wettability of rapidly solidified foils of Al-In alloys containing up to 4.7 at.% of In was investigated by means of sessile-drop method and atomic force microscopy. It was found that In significantly changes wetting properties of pure Al from a hydrophobic behaviour to a hydrophilic one. The effect of topography on the wetting properties of nano-rough foils demonstrates that an increase in In content up to 0.7 at.% resulted in a transition from a homogeneous to a heterogeneous wetting behaviour when decreasing the roughness of the surface makes it more hydrophilic. Streszczenie. Zwilżalność szybko skrystalizowanych foli stopu Al-In zawierających In do 4,7 at.% została zbadana za pomocą metody "siedzącej kropli" oraz mikroskopii sił atomowych. Określono, że dodatek In znacząco zmienia właściwości zwilżające czystego Al z hydrofobowych na hydrofilowe. Wpływ topografii na właściwości zwilżające nano-chropowatych folii przedstawia, że wzrost zawartości In do 0,7 at.% skutkuje w zmianie właściwości zwilżających z homogenicznych na heterogeniczne oraz zwiększająca się chropowatość powierzchni powoduje, że stają się one hydrofilowe.

Vertically aligned MoS nanosheets (NSs) with exposed edges were successfully synthesized over a large area (∼2 cm). The NSs were grown using an ambient pressure chemical vapor deposition technique via rapid sulfurization of sputter deposited thick molybdenum films. Extensive characterization of the grown MoS NSs has been carried out using high resolution scanning and transmission electron microscopy (SEM & TEM). A special care was given to the TEM lamella preparation process by means of a focused ion beam to preserve the NS growth direction. The cross-section TEM measurements revealed the growth of densely packed, vertically aligned and straight MoS NSs. Additional characterization techniques such as atomic force microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, and photoluminescence (PL) were used to evaluate the MoS NSs. These studies revealed the high crystallinity and quality of the synthesized NSs. The MoS NSs show visible light emission similar to mechanically exfoliated monolayer MoS NSs. The striking PL signal comes from the exposed edges as shown by experimental and theoretical calculations. The vertical MoS NSs also exhibit a hydrophobic character with a contact angle of 114°. The as-grown MoS NSs would be highly useful in the development of catalysis, nano-optoelectronics, gas-sensing and bio-sensing device applications.
