“…Figure 4 shows the FTIR spectrum obtained for the superhydrophobic copper surface. A broad peak around 3411 cm −1 along with the peak around 1606 cm −1 accounts for OH stretching vibration [23][24][25][26]. A sharp peak at 614 cm −1 is accounted by the presence of halogens such as chlorine and fluorine [23,26].…”

Artificial superhydrophobic copper surfaces play an important role in modern applications such as self-cleaning and dropwise condensation; however, corrosion resistance and durability often present as major concerns in such applications. In this study, the anti-corrosion properties and mechanical durability of superhydrophobic copper surface have been investigated. The superhydrophobic copper surfaces were achieved with wet chemical etching and an immersion method to reduce the complexity of the fabrication process. The surface structures and materials were characterized using scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectrometer (FTIR). The corrosion resistance and mechanical properties of the superhydrophobic copper surface were characterized after immersing surfaces in a 3.5 wt % NaCl solution. The chemical stability of the superhydrophobic copper surface in the NaCl solution for a short period of time was also evaluated. An abrasion test and an ultrasound oscillation were conducted to confirm that the copper surface contained durable superhydrophobic properties. In addition, an atomic force microscope was employed to study the surface mechanical property in the corrosion conditions. The present study shows that the resulting superhydrophobic copper surface exhibit enhanced corrosion resistance and durability.

“…The main aim of the present investigation is fabrication of low-cost S.H Cu and Al nanoparticles and extending their application towards the catalysis field. For the synthesis of S.H Cu or Al metal plates, a standard literature procedure was followed [35]. The Cu or Al plate with the area of 12 cm 2 was taken as a source material.…”

Cu and Al nanoparticles were prepared using a simple chemical etching method followed by a chemical reduction method. The synthesized metal nanoparticles were characterized by Fourier transform infrared (FTIR) spectroscopy, UV-visible spectroscopy, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (HRTEM), electron-dispersive (EDX) spectrum and water contact angle (WCA) measurements. The application of Cu and Al nanoparticles was tested towards the catalytic reduction of 4-nitrophenol (NiP), hexavalent chromium {Cr(VI)} and rhodamine 6G (R6G) dye in the presence sodiumborohydride (NaBH 4) as a reducing agent. From the UV-visible spectrum, the reduction rate constant (k app) and the induction time (T i) were determined and compared critically. The HRTEM analysis confirmed the nanosize of Cu and Al prepared by a simple chemical etching process followed by the chemical reduction method.

The Mn 2+ and Mo 6+ based Metal-mercaptoacetate (Metal-MA) hybrids were prepared by a simple acidbase titration method. The prepared Metal-MA hybrids were analysed by FT-IR spectroscopy, UV-visible spectroscopy, SEM, particle size analyser (PSA), XRD and EDX. The prepared Metal-MA hybrids were investigated to assess their catalytic activity for ring-opening polymerization (ROP) of ε-caprolactone (CL) in the absence of an initiator at 160 o C in N 2 atmosphere by varying the catalyst concentration and temperature. The catalytic activity of the Metal-MA hybrid towards the ROP of CL was concluded by the FTIR-RI method. The % yield, degradation temperature (T d ), melting temperature (T m ) and molecular weight (M w ) of poly(ε-caprolactone) (PCL) were also investigated. The structure of PCL was comprehended by analysing its NMR spectrum. The activation energy (E a ) for the ROP of CL was determined as 10,363 Kcal/mol. A linear increase in M w of PCL with the increasing [M 0 /I 0 ] ratio was also noticed.
