Abstract

PbSe thin films were grown onto glass substrates by chemical bath deposition method. Structure and surfacemorphology of thin films were characterized by X-ray diffraction and scanning electron microscopy. The band gapenergy and type of optical transition were determined from optical absorbance data. The deposition parameters wereoptimized to obtain good quality of thin films. X-ray diffraction indicates that the films have cubic structure. TheSEM micrograph showed the films do not cover the glass substrate completely and consisted of irregular shapedgrains. The films show good optical properties with high absorption in the visible region and the band gap value wasestimated to be 1.3 eV.

Abstract

Lead selenide thin films were prepared by chemical bath deposition method using aqueous of lead nitrate, sodium selenate and sodium tartrate. The influence of bath temperature towards the properties of the thin films was studied. The films were characterized by X-ray diffraction, scanning electron microscopy and UV-Vis spectrophotometer. The XRD results confirmed the polycrystalline cubic structure of PbSe films. The intensity of major peak at 2ϴ = 25.1° which belonged to (111) plane of PbSe, increased with bath temperature from 40 to 80 °C. The SEM micrographs showed that the most homogeneous surface and larger grain sizes could be seen for the films deposited at 80 °C as compared with other bath temperatures.

Abstract

Corrosion represents a major challenge in industrial systems due to its detrimental impact on the performance, safety, and durability of metallic materials, particularly carbon steel in acidic environments. This study evaluated the effectiveness of sikkam bark extract (Bischofia javanica Blume) as an eco-friendly corrosion inhibitor for carbon steel in sulfuric acid (H2SO4) solution. The extract, obtained via maceration using 96% ethanol, was applied in various concentrations to 15% HSO media, with specimens immersed for 24 hours at 30C. The corrosion behavior was analyzed through gravimetric measurements, pH monitoring, and surface morphology characterization using scanning electron microscopy (SEM). The highest inhibition efficiency of 95.56% was achieved at 5% inhibitor concentration in 5% H2SO4, accompanied by a significant reduction in mass loss and corrosion rate. The increase in solution pH after immersion confirmed the neutralization of H ions and the formation of a stable passive film composed of tanninFe complexes on the steel surface. SEM analysis further revealed a compact and continuous organic layer responsible for suppressing ion diffusion and electron transfer. These results demonstrate that sikkam bark extract functions as a highly efficient and sustainable green inhibitor, offering strong potential for corrosion mitigation in acidic environments relevant to petrochemical and industrial applications
