Special Issue Information

Dear Colleagues,

Contemporary enterprises are embracing technological innovations, and emerging ideas in the manufacturing-industry in order to preserve and outperform from the perspective of value-addition, and quality at the affordable price. Manufacturing sectors are continually on the lookout for novel, innovative-materials due to the rapid evolution of technologies, and the desire for exceptional mechanical, thermal, abrasion, and physical-traits at a minimal-price. Composites has suddenly becoming extensively utilized around the entire globe owing to its remarkable characteristics and ease of processing. Since composite materials have been made up of 2 or more constituents, usually surpass matrix-materials. Among three most prevalent forms of composite includes, metal-matrix composites, polymer-matrix composites, and ceramic-matrix composites. Hybrid metallic-matrices or polymer-matrix composites, in particular, were developed to enhance properties via., reinforcing them with two distinct metallic particulates or fibers. Formerly, auto-maker companies including such Mercedes-Benz, Audi, B.M.W., and Volks-wagen had used composites to manufacture internal & external components. Furthermore, such composites are employed throughout the building construction, industrial applications, pharmaceutical, defense, and pharmaceutical industries, as well as the manufacture of suitcases, sport-goods, and protective helmets. The above special-section intends to disseminate innovative conjectural, operational, & methodological breakthroughs, considerable notable technological applications, case analysis, original research articles, and study findings in domains including such as fabrication, analysis, optimization, and experimentation on an advanced hybrid-composites for innumerable engineering and biomedical applications. One such special-issue encourages original articles, critical/comprehensive/mini-reviews, peer - reviewed scholarly case-study articles on hybrid composite materials, which do have numerous applicability in the automobile, building construction, aircraft, military, defense, electronics, aeronautical, pharmaceutical, and biomedical sectors. Amongst some of an emerging theme cluster include, but are not confined to, the following:

  • composite derived from natural fibres
  • techniques for producing bio-based polymer composites and their physicomechanical, structural, biomechanical, thermal, chemical, damping, tribological properties
  • machining behaviour with microstructural, topographic, surface morphological analysis
  • composites with something like a ceramic-matrix
  • hybrid biocompatible functional composites
  • conducting, and non-conducting composites
  • composites with such a hybrid metal-matrix material
  • polymer composites made from naturally occurring fibres that have been functionalized
  • polymer composites made from naturally occurring fibres that have been functionalized
  • reinforced polymers with fibre treatment
  • surfaces characteristics & machinability or processability of composite materials

The increased use of plastics has led to severe environmental pollution, particularly by microplastics—plastic particles 5 mm or less in diameter. These particles are formed by environmental factors such as weathering and ultraviolet irradiation, thereby making environmental pollution worse. This environmental pollution intensifies human exposure to microplastics via food chains. Despite potential negative effects, few toxicity assessments on microplastics are available. In this study, two sizes of polytetrafluoroethylene (PTFE) microplastics, approximately 5 μm and 10–50 μm, were manufactured and used for single and four-week repeated toxicity and pharmacokinetic studies. Toxicological effects were comprehensively evaluated with clinical signs, body weight, food and water consumption, necropsy findings, and histopathological and clinical-pathological examinations. Blood collected at 15, 30 60, and 120 min after a single administration of microplastics were analyzed by Raman spectroscopy. In the toxicity evaluation of single and four-week repeated oral administration of PTFE microplastics, no toxic changes were observed. Therefore, the lethal dose 50 (LD50) and no-observed-adverse-effect-level (NOAEL) of PTFE microplastics in ICR mice were established as 2000 mg/kg or more. PTFE microplastics were not detected in blood, so pharmacokinetic parameters could not be calculated. This study provides new insight into the long-term toxicity and pharmacokinetics of PTFE microplastics. Full article

The interaction of copaiba oil in the polymer matrix of chitosan can produce a favorable synergistic effect and potentiate properties. Indeed, the bioactive principles present in copaiba oil have anti-inflammatory and healing action. In the present work, chitosan membranes containing different contents of copaiba oil copaíba (0.1, 0.5, 1.0 and 5.0% (v/v)) were for the first time investigated. The membranes were developed by the casting method and analyzed for their morphology, degree of intumescence, moisture content, contact angle, Scanning Electron Microscope, and X-ray diffractometry. These chitosan/copaiba oil porous membranes disclosed fluid absorption capacity, hydrophilic surface, and moisture. In addition, the results showed that chitosan membranes with the addition of 1.0% (v/v) of copaiba oil presented oil drops with larger diameters, around 123.78 μm. The highest fluid absorption indexes were observed in chitosan membranes containing 0.1 and 0.5% (v/v) of copaiba oil. In addition, the copaiba oil modified the crystalline structure of chitosan. Such characteristics are expected to favor wound treatment. However, biological studies are necessary for the safe use of chitosan/copaiba oil membrane as a biomaterial. Full article
