The production of these types of structures utilizes the superior properties of each layer contained within the structure. This study addresses the acoustic performance of nonwoven surface structures fabricated in different thicknesses and densities using chicken feather fibres in different constructions. An impedance tube was used to determine the sound absorption and sound transmission loss values of two-layer structures of different densities and thicknesses. The results show that the influence of the layer in front or behind on the values of sound transmission losses is very limited in two-layer structures with varying densities and thicknesses. However, for the degree of sound absorption, it is important which layer is closer to the sound source. These findings are based on an analysis of multifactorial experimental data. Accordingly, the sound absorption coefficients and sound transmission loss values of all two-layer structures decrease slightly with increasing sound frequency in the frequency range of 63–200 Hz and then increase. The low-density layer on the front of the combined structure ensures better sound absorption at low and medium frequencies. As the density of the front layer increases, its ability to absorb sound decreases. It has been found that the sound absorption capacity of structures with a low density on the front and a thick layer on the back is highest.</p></div>","PeriodicalId":502,"journal":{"name":"Bulletin of Materials Science","volume":"49 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145930015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of ultrasonic energy, leading to shear forces, reducing the lateral size of GO flakes, thus producing more uniform nanosheets, is clearly discernible. Characterizations including XRD, Raman, FTIR, TEM and UV-vis are shown to support the control influenced by sonication vis-à-vis reduction of particle size and control of flake morphology. Maximum gas sensing response characteristics were observed for GO sample that has been sonicated for 90 min.

Due to its superior high-temperature properties and eco-friendliness, it has gained importance as a refractory material for use in steel-teeming ladles, cement rotary kilns and glass tank furnaces. Apart from refractory, polycrystalline MAS is extensively used in optically transparent windows, armours and domes, owing to its high transparency with acceptable pyro-chemical properties. MAS formation from alumina and magnesia involves a volume expansion of 5–8%, which prohibits the formation of dense MAS bodies through a single-stage sintering process. As a result, a more expensive double-stage firing process is required to produce dense MAS ceramics. However, various additives play a significant role in the formation and sintering of MAS through the reaction sintering process. Research has shown that halide doping can lower the spinel formation temperature, enhance densification during sintering and modify the microstructure of MAS, resulting in a notable improvement in its thermo-mechanical properties.
