Abstract

Nanomaterials have various unique properties and characteristics so that they can apply in many sectors. One of the most popular nanoparticles today is magnetite nanoparticles. Magnetite particles have several properties such as being super magnetic, having a high saturation field, chemical stability, biocompatibility, and low production costs. The purpose of this article is to review the synthesis of magnetite nanoparticles and their application to Glassy Carbon Electrode (GCE) modification. This modified GCE can applied as an electrochemical sensor to detect various organic and inorganic substances. In this study, type synthesis methods of magnetite nanoparticles which taken from kind literature well investigation include coprecipitation, sol-gel, microemulsion, hydrothermal, and thermal decomposition. The five routes have their respective advantages and disadvantages. Then the nano magnetite made can applied to modify the GCE as an electrochemical sensor that can detect uric acid, bacteria, and even metals dissolved in water.

Abstract

Fe3O4 nanoparticles are magnetic materials that can use in various fields. Fe3O4 particles have several properties such as being super magnetic, having a high saturation field, being chemically stable, biocompatibility, and low production costs. The purpose of this study was to conduct a bibliometric analysis of the research on the production of Fe3O4 nanoparticles by using mapping analysis with VOSviewer software. The data used in the study were obtained and collected using the Publish or Perish software. The data obtained were obtained based on the keywords "magnetite, nanomaterial, Fe3O4 nanoparticle, production". Based on the analysis conducted, it was found that 994 articles relevant to the keywords used were obtained in the 2017-2021 range. The results show that the production of Fe3O4 nanoparticles increased from 2017-2019 and decreased after that. This research is expected to help and become a reference for other researchers as consideration for determining the research theme to be taken.

Abstract

Shell and tube heat exchangers are one of the most widely used types of heat exchangers in industry. The low cost of manufacture and use is one of the reasons this heat exchanger is widely used. The purpose of this research is to design a shell and tube heat exchanger (two-pass) type for application in the production of magnetite particles on an industrial scale. To design a heat exchanger, the method used is mathematical calculations using more than 20 equations that are used which are derived based on the influence of dimensional and fluid specifications. In the production of magnetite particles, two heat exchangers are used, namely the reaction process and the crystallization process. The results of this study indicate the effectiveness of the two heat exchangers designed to have a high enough value and exceed 70%. This high effectiveness value indicates that both heat exchangers have good performance. Therefore, this design has the potential to be applied to the magnetite particle synthesis process on an industrial scale.
