Heavy metal contamination has contaminated the world, particularly in developing countries. This research was designed to determine the performance of starch/eggshell/orange peel-activated carbon-based composite films in removing cadmium ions from water samples. The composite film removed 100% and 99. 7% of the Cd 2+ ions in 0. 5 mg L u22121 and 1. 0 mg L u22121 Cd 2+ ions, respectively, although the maximum removal rate for methylene blue was 93. 7 percent. According to the current report, starch/eggshell/orange peel activated carbon film has a high likelihood for commercial activated carbon as a low-cost adsorbent.

This report is focusing on the study of carbon film morphology and characteristics obtained by thermal chemical vapor deposition of various substrates during the manufacture of carbon nanotubes. The wear resistance index and nanoindentation were compared together with nanoindentation, hardness, and elastic modulus. According to this report, it may be remarked that the retrieved film is described as an amorphous carbon film.

Ionic liquids have particulars that make them suitable candidates for either new base oils or additives. Lubricating characteristics of cyano-based ionic liquids have been investigated on particular tetrahedral amorphous carbon films. After lubrication, the ta-C film/ta-C film contact interface exhibits remarkable low friction. The new research investigated the lubrication mechanism of cyano-based ionic liquids against ta-C films. Lubricants were used as lubricants by 1-Butyl-3-methylimidazolium dicyanamide and 1-butyl-3-methylimidazolium tricyanomethane, the former having a low friction coefficient of 0. 03. The ta-C film at high temperatures may have contributed to the decrease in friction between the films. Similarly, anion adsorption on the worn surface at elevated temperatures resulted in reduced friction. However, the TGA results revealed a different trend than the sliding test's. Our findings reveal that the cyano-based ionic liquids underwent tribo-decomposition at low temperatures. A minimum temperature was also required for anions adsorption onto the sliding surface.

A hydraulic servo-actuator is a vital aircraft control device whose sealing job directly impacts the aircraft flight attitude's sensitivity and accuracy. Foreign insecure particles in hydraulic oil can cause the fragile friction pair wear and the leak; they may even lead to oil spill accidents. A collection of Ag-DLC films was deposited in Then, Utah; the Ag-DLC films' structure and combined tribological results were investigated. The intensity of the Ag crystal face in the films increases as a result of Ag content, as shown by the results. Both soft Ag particles and a graphitized top layer act as solid lubricants, as the film's toughness increase. Ag doping makes the film toughness increase; the film's toughness improves; both soft Ag particles and a graphitized top layer act as solid lubricants. Our results may lead to a novel way to make DLC film usable for improving hydraulic servoactuator seal performance. Based on the experimental findings, a mechanism behind Ag-DLC film conversion is also shown.

SPANI was electrodeposited on the CNP-film by electropolymerization of aniline and o-aminobenzene sulfonic acid comonomers in solution by electropolymerization. The success of SPANIu2212CNP-based supercapacitors is highly dependent on the granular ratio of AN/SAN. At the charging current density of 0. 5 Ag22121, the optimal results of SPANI/SAN ratio of 1. 0 exists, with the specific capacitance of 273. 3 Fg/u22121 at the charging current density of 0. 5 Ag22121.

With a different proportion of hydrogen supply in deposition, the evolution of hydrogenated amorphous carbon films with fullerene-like microstructure was investigated. The deposited films showed a reduced compressive strain, increased elastic recovery, and higher hardness than films that were not deposited without hydrogen introduction. The results revealed a hydrogen flow rate of 50 sccm.

The aim of this research was to investigate the effects of the elemental elements in a DLC film on its biomedical applications. Using a surface roughness tester, the average surface roughness of films was found. Film hardness and elastic modulus of films were determined by using a nanoindentation hardness tester. By a contact angle measurement, the surface contact angle was determined. The MTT assay cytotoxicity test was used to determine film biocompatibility of films. The results reveal that the Si-N-DLC film has the highest hardness and friction coefficient with a nitrogen content of 0. 5 at. %N, while the Si-DLC film with silicon content of 14. 2 at. %Si has the highest contact angle and corrosion potential. This is a substantial improvement over the uncoated AISI 316L's average cell viability percentage of 81. 9 percent, which is lower than the uncoated AISI 316L.

Utilizing our newly invented molecular dynamics technique, we theoretically investigated the implications of film deposition condition on a friction of diamond-like carbon film. Due to friction-induced structural change, the friction coefficient for the deposited film with kinetic energy of 1 eV was much smaller than that of ten and 30 ev cases. Simulations gave us a crucial insight into DLC film preparation for a low friction regime.
