Research ArticleOpen accessEvery word in the titleNanomodified Adhesive Composition for Aeronautical Structures Based on Polymer Composite MaterialsVladimir Dmitrievich Vermel, Sergei Anatol’evich Titov, Yuriy Vital’evich Kornev et al.Computer simulation of the properties of Nanomodified Adhesive Compositions (NMC) based on ED-20 epoxide resin doped with carbon nanomaterials was carried out. It is shown that open carbon nanotubes are an efficient additive to increase mechanical shearing properties of adhesive compositions based on epoxide matrix. Using the nanoindentation method it was found that introduction of carbon nanotubes into adhesive compositions … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 14 Mar 2016 · 7,295 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparative Analysis of Surface Microhardness and Antimicrobial Activity of Conventional and Bioactive Composite Materials for Dental RestorationsBruno Fongaro Dalbosco, Rafael da Silva Vanolli, Poliana Maria de Faveri Cardoso et al.This study evaluated the fluoride release capability, antimicrobial activity, and surface microhardness of bioactive composite resins, critical properties for the effectiveness and durability of dental materials in restorative procedures. Conventional and bioactive composite resins with varying viscosities were tested. Specimens of each resin type were prepared and stored in physiological saline solution for 24 hours to simulate oral conditions. Surface … …Current Research in Dentistry, Vol. 16, Issue 1 · 29 Jan 2026 · 2,809 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExploring the Impact of Incorporating Fine-Grained Materials on the Resistance Characteristics of Cement-Reinforced ClaySayed Amirhossein Hosseini Chaleshtori, Mohammad Alibabaei ShahrakiThis study, conducted with meticulous attention to detail, examined the influence of fine-grained materials on the resistance components of clay, with and without cement reinforcement. Micro-silica, perlite, crystal barite, gypsum, silica and talc were added to investigate this matter and samples were created and modeled under standard laboratory conditions. The current study aimed to examine the effectiveness of organic granules … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 13 Aug 2024 · 5,579 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleBio-Inspired Materials: Exhibited Characteristics and Integration Degree in Bio-Printing OperationsAntreas KantarosIn the last decade, additive manufacturing techniques, commonly known under the term "3d printing" have seen constantly increasing use in various scientific fields. The nature of these fabrication techniques that operate under a layer-by-layer material deposition principle features several de facto advantages, compared to traditional manufacturing techniques. These advantages range from the precise attribution of pre-designed complex shapes to the … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 29 Nov 2022 · 7,180 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCollection and Processing of Medicinal Raw Materials from Some Rare Plants in the Forest-Steppe Zone of Northern KazakhstanMarat Tynykulov, Svetlana Derbush, Marina Kuznetsova et al.Rare endemic plants of the forest-steppe zone of Northern Kazakhstan, including Adonis vernalis, Adonis wolgensis, Pulsatilla patens, and Pulsatilla multifida, represent valuable medicinal resources whose sustainable utilization requires optimized harvesting, processing, and conservation strategies. This study evaluated the effects of drying conditions, environmental factors, extraction techniques, and biotechnological approaches on the yield and quality of bioactive compounds from these species. … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 1 Apr 2026 · 1,595 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Influence of Trichoderma viride Cellulase Enzyme Concentration on Saccharification of Waste Paper MaterialsKhomotso M. P. Mokatse, M. Alfred Mogale, J. Pieter H. Van WykEnzymatic hydrolysis of lignocellulosic materials is one of the major steps in the commercialization process of converting cellulosic substrates into bio-products. The saccharification of lignocellulosic materials is usually achieved by a synergistic action of an enzyme mixture consisting of multiple cellulase enzymes such as endo-and exo-glucanase, cellobiohydrolase and β-glucosidase with different mode of actions. During the enzymatic hydrolysis of the … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 28 Oct 2021 · 6,456 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleA Systematic Study of the Novel Materials used in Solar Cell Technologies, Opportunities and ChallengesAayush Kumar Choudhary, Godwin Glivin, N. Kalaiselvan et al.This study aims to review the present progress of integrating the PV cell with other prominent mainstream photovoltaic cell materials. The combination of the materials in a thin film electric cell is advantageous due to the reduction within the material usage and therefore the rise in efficiency. Amorphous Silicon (α-Si), Cadmium Telluride (CdTe) and Copper Indium Gallium Selenide (CIGS) are … …Energy Research Journal, Vol. 11, Issue 1 · 2 Nov 2020 · 7,356 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Various Combustible Materials on Insulating Properties of Refractory BricksIsiaka Olajide Odewale, Ebere Monica Ameh, Victor Tyonenge Dhave Amaakaven et al.The effect of various combustible materials on insulating properties of refractory bricks produced from Enugu fire clay and Ekebedi clay has been studied.
