The paper addresses the methodology for obtaining biocomposite structures from waste, with sound-absorbing properties, such as: thuja shells, walnut pistachio beech sawdust, pumpkin seeds shells and sunflower shells. experimental analysis carried out considers study of properties held by proposed new materials, determining value sound absorption coefficient, reflection impedance ratio, using Ku...

Abstract Robust and affordable technology capabilities are needed before a sustained human presence on the lunar Martian surfaces can be established. A key challenge is production of high-strength structural materials from in situ resources to provide spacious habitats with adequate radiation shielding. Ideally, such will achieved through relatively simple, low-energy processes that support oth...

Calcium carbonate has the potential to be used in development of medical materials, including biomaterials. Biocomposite is composed CaCO3 as matrix material and bioplastic from combination corn starch cassava reinforcement. This study aims determine mechanical properties such tensile strength bending/flexural with varying compositions bioplastic. Characterization biocomposite uses Scanning Ele...

nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (pva), poly (ε-caprolactone) (pcl) and nanohydroxyapatite  (nha) were fabricated by electrospinning method in this study. the composite nanofibrous scaffolds were subjected to detailed analysis. morphological investigations revealed that the...

Abstract Microalgae and cyanobacteria are effective platforms for environmental remediation (phycoremediation), particularly of air water. There is limited scope to deploy suspension cultures due space, cost maintenance challenges—driving an imperative towards biofilm-based treatment systems; however, these systems ill-equipped rapid mobile deployment. In this study we explored the main technic...
