“…Superhydrophobicity is a feature of the surface morphology rather than surface chemistry. It has been shown that a hierarchical structure can produce a superhydrophobic phenomenon [21]. This type of topography is characterized by the pyramid-like structure.…”

Superhydrophobic anticorrosion layers of various thicknesses were deposited onto low carbon steel. The layer is comprised of MnO2/Polystyrene nanocomposite with a hierarchical structure. AFM imaging of the nanocomposite illustrated a very rough surface with rms roughness of 109 nm. A polarization method was applied to measure the corrosion potential and corrosion current by using a potentiostat device. Two corrosive solutions were utilized in this study (NaCl & HCl). Strong concentrations of 1M HCl and 5000ppm NaCl were used in this work. The results revealed that the nanocomposite exhibits better corrosion inhibition after 24h immersion time in NaCl compared to HCl, where the corrosion current density is 0.56 μA/cm2 in NaCl against 24.3 μA/cm2 in HCl. The uncoated sample presented a higher corrosion current density after 24h immersion time with values of 14.4 μA/cm2 and 83.6 μA/cm2 in NaCl and HCl, respectively. Moreover, the ultrathin layers of the nanocomposite demonstrated better corrosion inhibition than the relatively thicker layers. This result was elucidated by the peeling effect of the thick samples. Immersion time was also considered in this study by leaving the samples over a course of 30 days in the solution and performing the measurements for every 10 days’ span. The activation energy of the surface was determined using Arrhenius method by varying the solution temperature during measurements. Corrosion protection efficiency showed excellent results with up to 96.1% in NaCl solution. Pitting potential was also determined in this work.

“…One of the pre-calibrating colour correction techniques is taking three separate images with each different colour channel. Boult et.al [6] managed to use only single image by wrapping the red and green channel to the blue channel and then fitting the edge displacement with cubic splines and blue edge is used as reference. The trade off with this method is the extracted map will be dependent on the relative density and distribution of the edge.…”

With the advent of computing power and higher resolution CMOS sensor, imaging camera for mobile phone application has become very common in consumer portable product such as mobile phone, tablet or even wearable devices and head mount devices . Higher resolution image sensor, on the other hand, will suffer chromatic aberration (CA) where the colour channel appears shifted. Better lens design with more lens elements may be required. However, this will add more cost and manufacturing challenges. Many studies and methods have been proposed for CA correction through post image processing and those methods required calibration or post image process before correction factor can be applied. In this paper, we propose a new algorithm that will pre-defined the CA correction factor through lens design simulation.

“…Due to a decrease in carrier concentration caused by carrier traps at the grain boundaries, the resistivity and band gap of doped films increase with increasing dopant concentration [10]. Tin-doped ZnO structures obtained by different methods such as Successive Ionic Layer Adsorption and Re-action (SILAR), spray pyrolysis and sol-gel methods have been reported [9,11,12]. However, there is no study about tin-doped ZnO films derived by the chemical bath deposition (CBD) method.…”

In this paper, undoped and tin-doped ZnO nanostructures were grown onto non-conductive substrates by a simple solution method. Structural, morphological, optical and electrical properties of the structures were investigated with respect to tin concentration. From XRD studies, all the ZnO nanostructures were found as hexagonal wurtzite type structures growing preponderantly oriented with c-axis nor- mal to the substrate. An increase in tin content resulted in a decrease in grain size, whereas the dislocation density in- creases. SEM observations indicated that all the structures were textured throughout the substrates without any cracks or pores. The influence of incorporation of tin on surface morphology of the samples was clearly seen. Average diameter of the nanostructures decreased with increasing tin content. Absorption spectra of the structures revealed that the band gap of the films increases with increasing tin concentration. It is found that the tin-doped samples have higher average transmittance than the undoped one. The 1 % tin-doped sample exhibited ∼80 % average transparency, which was the best transparency among the doped samples. Electrical measurements showed that resistivity of the structures increased with increasing dopant concentration. This increasing was attributed due to a decrease in carrier con- centration caused by carrier traps at the grain boundaries.
