The vibrational properties of sub micrometer size Fe-based oxides were investigated by Raman mapping along with chemometric analysis with the aim of probing their chemical composition. Highly contrasted Raman spectra were recorded from several inclusions embedded at different spatial locations.

A field study was performed to examine the environmental problems caused by Bio Waste Material that is made up of Perna Viridis (PV) shells, the latter of which is a common type of mussel found in Bang Ja Kreng Community, Samut Songkhram Province. This area is a fishery location and experiences vast quantities of shell waste, which ultimately impacts community pollution. It is not possible to dispose of this waste in a traditional manner and there are no specific locations where the shells can be dumped. Consequently, most people secretly dispose of them in mangrove forests or along public roadsides. Thus, in order to facilitate future use, the researcher conducted an analytical investigation to examine material performance. The temperatures at which mussel shells were burned were 400, 800, and 1200 °C. An X-ray diffractometer (XRD), a device that examines X-ray diffraction through layers of atoms or molecules in materials or sample substances, was Utilised to Analyse their elements. Furthermore, this analytical investigation also included X-ray fluorescence (XRF) as a tool to examine the elemental compositions. It was discovered that burning altered the chemical structure at different temperatures. Portland cement contained the same components. It was revealed that CaO constituted as much as 80.14 % of the weight below 1200 °C. In general, CaO was discovered to constitute up to 64.73 % of the weight when comparing cement. It is a substance that is used to research cement reduction when manufacturing Bio-Responsive Blocks. In order to compare lower costs and larger profits, the compound was divided into different ratios. An ANSYS simulation was used to Analyse the material properties and create three models: one for a single concrete Block and another for an 80 × 80 cm wall. The experiments did not involve the use of columns or beams. Instead of using the wall as a load-bearing wall, the goal was to add value to the product processing of mussel shell waste and determine how it can be recycled and reused beneficially (i.e., to improve sustainability or create a pleasant community environment.</p></div>","PeriodicalId":101087,"journal":{"name":"Results in Materials","volume":"23 ","pages":"Article 100589"},"PeriodicalIF":0.0,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590048X24000633/pdfft?md5=5af0b120c0537325876b8de3ec14d680&pid=1-s2.0-S2590048X24000633-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141435123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The breakdown voltage of epoxy resin modified by silicate ester is up to 181 MV/m, which is increased by 50 % compared to pure epoxy resin. The silicate ester curing agent can react with both epoxy resin and silica fillers and can thus improve the dispersion of the fillers in the matrix and enhance the interaction between fillers and the resin.
