“…The FE-SEM images of bare SiC particles and the EDX spectrum analysis are shown in the Fig. 3(a, b and c) which was already published elsewhere [36]. The FE-SEM examination indicate that the SiC particles are coated with Al 2 O 3 and ZnAl 2 O 4 nano-particles as shown in Fig.…”

“…However, as similar PXRD pattern were not available in the literature, so it was difficult for us to exactly compare the PXRD pattern . But it matches well with recently reported PXRD pattern of Cu(II) Schiff base complex in nanodimension . So it can be concluded that probably the nanostructured Cu(II)‐SB‐NR material is formed via extension of linkage in the co‐ordination sphere of Cu‐Schiff base complex leading to nano‐rod like structure.…”

Simultaneous transformation of structural morphology, material dimension and oxidation state of Cu (II)‐nanorod was achieved with 3‐(Triethoxysilyl)propylamine, (APTS) and 4‐nitrobenzaldehyde (4‐NB) under non‐hydrothermal condition. Morphology of the modified Cu(I) material was found to resemble with the leaf of colocasea. Conversion of a Cu(II) based nono‐material to a Cu(I)‐based micro‐material was confirmed from EPR, MAS‐ NMR and cyclic voltametric (CV) study. BET‐surface area, Raman signal intensity and thermal stability of the Cu(I)‐microleaf was greatly enhanced due to presence of Cu‐O−Si linkage. Both the Cu(II) and Cu(I) material were found to be effective catalyst systems for nitro‐aldol reaction as well as catalytic oxidation of methylene blue (MB) dye in presence of H2O2. High %yield (>90 %) of nitro‐aldol product was obtained with both the catalyst. Catalytic reaction under microwave irradiation was found to bring substantial decrease in reaction time. Cu (II)‐material was however not recyclable because of its soft nature. While the Cu(I)‐microleaf was recycled upto four consecutive cycles. These materials were found to degrade methylene blue dye within 20 min in presence of H2O2 but in absence of light. Dark phase catalytic oxidation of MB was monitored both via UV‐vis and cyclic voltametric study.

In order to solve the problem of dust accumulation on the fin surface of a mine air cooler, a method of preparing super-hydrophobic polyurethane (SPU) coating based on waste cooking oil (WCO) was proposed. Firstly, the polyurethane prepolymer was synthesized with WCO as a raw material, and then the polyurethane prepolymer was modified with amino-terminated polydimethylsiloxane (ATP) to obtain SPU emulsion. The chemical structure and thermal stability of SPU were characterized by infrared spectrum and thermogravimetric analysis. A series of nanocomposites were prepared by combining modified silicon carbide (APT-SiC) particles and SPU emulsions. According to the parameters of pull-off strength, contact angle, sliding angle and thermal conductivity, the filler ratio of nanocomposites was optimized. The test results show that when the content of APT-SiC particles is 20 wt %, super-hydrophobic polyurethane coating can be obtained. The coating has good pull- off strength and thermal conductivity, and the contact angle and sliding angle are 161° and 3°, respectively. In addition, the practical application of the super-hydrophobic polyurethane coating was tested by related experiments. The experimental results show that the coating has good self-cleaning, wear resistance and anti-corrosion performance, can meet the requirements of air coolers in special environments, and has great application prospects.
