The journal aims to provide a forum for the disseminations and exchanges of scientific and technological knowledge based on original research works among those linked to advanced coatings study, development and/or production, focusing in different areas such as wear-resistant coatings, corrosion protective coatings, optical protective coatings, films for biomedical and energy purposes, decorative coatings, and others, produced by advanced techniques such as PVD, CVD, thermal projection, etc.</span></span></span></p> en-US <h4>Policy for Journals/Articles with Open Access</h4> <p>Authors who publish with this journal agree to the following terms:</p> <ul> <li>Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank" rel="noopener">Creative Commons Attribution License</a> that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.<br /><br /></li> <li>Authors are permitted and encouraged to post links to their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work</li> </ul> <h4>Policy for Journals / Manuscript with Paid Access</h4> <p>Authors who publish with this journal agree to the following terms:</p> <ul> <li>Publisher retain copyright .<br /><br /></li> <li>Authors are permitted and encouraged to post links to their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work .</li> </ul> support@lifescienceglobal.com (Support Manager) support@lifescienceglobal.com (Technical Support Staff) Wed, 30 Aug 2023 14:44:45 +0000 OJS 3.3.0.10 http://blogs.law.harvard.edu/tech/rss 60 Simulation and Experiment Analysis of Driveshaft https://lifescienceglobalca.com/index.php/jcst/article/view/9233 <p>A driveshaft is a small spring coil less than 1mm in diameter, composed of several stainless-steel wire filaments. In intervention, the driveshaft is used to transmit force and motion to the inside body through the existing micro channels (such as arteries, veins, and gastrointestinal tract). The performance of the driveshaft determines the efficiency, stability, and accuracy of force and motion transitions, the ability to pass through tortuous microchannels, and the damage to healthy tissues. To determine the influence of fabrication parameters (filament, wire diameter, and outer diameter) on the mechanical properties (such as bending stiffness and natural frequency) of the driveshaft, a simulation was established in ABAQUS to calculate the deformation displacement under 0.0098N and first-order natural frequency. Then, the bending stiffness is calculated. The results show that the bending stiffness and the first-order natural frequency of the driveshaft increase with the increase of the filament number and wire diameter, and with the outer diameter of the driveshaft increases, the bending stiffness increases, while the first-order natural frequency decreases. Finally, the simulation model is verified by measuring the deformation displacement in the experiment. This study provides a methodology for designing and selecting the driveshaft in Interventional therapy.</p> Jia Hao Li, Yao Liu, Yang Zhou, You Zhe Wang, Zhan Ling Guo, Bin Shen Copyright (c) 2023 https://lifescienceglobalca.com/index.php/jcst/article/view/9233 Wed, 30 Aug 2023 00:00:00 +0000 Pycnometric-Additive Determining of the Degree of Coating of High-Strength Synthetic Diamond Grinding Powders using the Actual 3D Morphology of their Grains https://lifescienceglobalca.com/index.php/jcst/article/view/9413 <p>The methodological components of direct and indirect analytical determining of the degree of coating of synthetic diamond grinding powders are analyzed. It has been established that the weight method most used in practice for determining this technological property of grinding powder is not universal for different methods of applying the coating. More universal in this regard, as the review of publications showed, is the well-known indirect-analytical method based on the pycnometric-additive approach. An improved variant of this method is proposed, aimed at application to high-strength synthetic diamond grinding powders. The method takes into account the peculiarities of the 3D morphology of the grains of such powders. Using the example of grinding powder AC300 500/400, the grains of which were coated with a solution of a mixture of boron oxide, sodium silicate, and titanium carbide, the advantages of using the proposed method are illustrated. The results of a comparison of determining the degree of coating by a known method and its improved variant are presented.</p> G.A. Petasyuk, O.O. Bochechka, V.I. Lavrinenko, V.G. Poltoratskyi, Yu.V.
