In this paper, we present a method of generating nearly superhydrophobic surfaces from Femtosecond Laser Surface Processed (FLSP) metallic substrates and the study of their thermal stability at high temperatures. Using an FLSP process, hierarchical micro/nano structures were fabricated on stainless steel 316 after which a 200 nm Cerium Oxide (CeO2) film was sputtered onto the surface. Before Ce...

Ordered nanoporous silicas containing various binary copper-manganese oxides were prepared as catalytic systems for effective carbon monoxide elimination. The carbon monoxide elimination efficiency was demonstrated as a function of the [Mn]/[Cu] ratio and reaction time. The prepared catalysts were characterized by Brunauer-Emmett-Teller (BET) method, small- and wide-angle X-ray diffraction (XRD...

Structural macromolecular parameters of normal and treated (acid & alkali) polyester fibers have been investigated using Small Angle X-ray Scattering (SAXS) technique. Average diameters were calculated from Scanning electron microscope (SEM) micrographs and mechanical parameters were estimated using Instron. Further, crystallinity parameters of the same fibers have been determined using X-ray d...

The aim of this work was to make biodegradable plastics from renewable resources. Paper-based biodegradable plastics were produced via a sol-gel process by using zinc chloride solution. The optimum conditions were a zinc chloride concentration of 65%, reaction temperature of 70 °C, reaction time of 5 s, aging time of 3 h, and glycerol concentration of 10%. Fourier transform infrared spectroscop...

Mesoporous hydroxyapatites were syntesized by self-assembly method using Cetyltrimethylammonium bromide (CTAB) as cationic surfactant and 1-dodecanethiol as pore expander with pore expander/surfactant mass ratio of 4.22 and synthesis temperature of 80 °C in different micellization pH. The field emission-scanning electron microscopy (FESEM), x-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) ...

Nickel oxide thin film of various preferred orientations was deposited using sol-gel method using solvents including methanol. The resulting film was analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), contact angle measurement, and ultraviolet spectroscopy (UV-vis). Antibacterial activities of nickel oxide-based film against gram-negative bacteria (Escherichia coli) has...

The stability behavior of low immersion helical end milling processes is investigated in this paper. Low radial immersion milling operations involve interrupted cutting which induces chatter vibration under certain cutting conditions. Time Finite Element Analysis (TFEA) is suggested for an approximate solution for delayed differential equations encountered during interrupted milling. An improve...

Beeswax is used on wood furniture surfaces in China. expensive and has a low melting temperature, the wax film easily softened destroyed. To overcome these problems, modified polypropylene grafted with maleic anhydride, high temperature price, was hot-waxed wood. The adhesion, hardness, hydrophobic properties, heat resistance, color, gloss of woods were also examined. surface interfacial proper...

The high-pressure effect on valence fluctuation of the ThCr2Si2-type intermetallic compound EuNi2P2 has been investigated using in situ synchrotron Mössbauer spectroscopy (SMS). The isomer shift of Eu in EuNi2P2 increases monotonically with increasing pressure up to 50 GPa, suggesting a valence transition of the Eu from mixed toward trivalent. The synchrotron angle-dispersive X-ray diffraction ...
