Electrochemistry of Thin Films and Nanostructured Materials

Abstract

In the last few decades, the development and use of thin films and nanostructured materials to enhance physical and chemical properties of materials has been common practice in the field of materials science and engineering. The progress which has recently been made in tailoring the unique properties of thin films and nanostructured materials, such as a high surface area to volume ratio, surface charge, structure, anisotropic nature, and tunable functionalities, allow expanding the range of their possible applications from mechanical, structural, and protective coatings to electronics, energy storage systems, sensing, optoelectronics, catalysis, and biomedicine. Recent advances have also focused on the importance of electrochemistry in the fabrication and characterization of functional thin films and nanostructured materials, as well as various systems and devices based on these materials. Both cathodic and anodic processes are being extensively developed in order to elaborate new procedures and possibilities for the synthesis and characterization of thin films and nanostructured materials.

Studies of Benzotriazole on and into the Copper Electrodeposited Layer by Cyclic Voltammetry, Time-of-Flight Secondary-Ion Mass Spectrometry, Atomic Force Microscopy, and Surface Enhanced Raman Spectroscopy

“…Parameter a decreases as a function of wire position since the applied cathodic potential decreases. For C BTA ≥ 5 ppm, the parameter c is negligible, and the decrease in C BTA in the bracket of formula (5) is less than 10%. Parameter b is an important factor that plays a role in the correction coefficient for the whole range of applied overpotentials.…”

“…Copper electrodeposition plays an important role in the deposition of copper coatings with varied physicochemical properties that can be controlled by the composition of the electroplating bath, e.g., the applied current densities, the time of the deposition process, etc. [1][2][3][4][5][6]. Due to this reason, copper electrodeposited layers find numerous applications in nano-and micro-electronics [7], as well as as a decorative and protective layer [8].…”

Micro-Spectrometer-Based Interferometric Spectroscopy and Environmental Sensing with Zinc Oxide Thin Film

“…Figure 9b demonstrates the gas introduction device provided by TIRI for testing, which allows users to introduce test gas into the chamber by controlling the gas valve. Thin films are sensitive to environmental changes, with temperature being one of the key environmental factors [34,35]. Variations in temperature can affect the optical transparency and bandgap of zinc oxide films.…”

“…To ascertain the actual impact of environmental temperature on ZnO, this study utilized a heating plate to adjust the temperature of the thin film while measuring its interference spectra. The interference spectra at six different temperatures are presented in Thin films are sensitive to environmental changes, with temperature being one of the key environmental factors [34,35]. Variations in temperature can affect the optical transparency and bandgap of zinc oxide films.…”

Urchin-like Ce(HCOO)3 Synthesized by a Microwave-Assisted Method and Its Application in an Asymmetric Supercapacitor

“…Nanostructured materials have attracted great attention in recent decades due to their active domains on the surface compared to their corresponding bulk materials [ 1 , 2 , 3 ]. The hierarchical self-assembly of nanocrystals typically enhances mass transport, reduces diffusion resistance, and increases the surface area for adsorption and electrochemical reactions.…”
