Why is the yield of nanocellulose from vetiver root lower than straw and coir fibers?
5 answers
The yield of nanocellulose from vetiver root is lower compared to straw and coir fibers due to the differences in the starting materials and extraction processes. Vetiver root requires specific conditions like enriched rooting medium and precise irrigation levels for optimal growth potential and root character improvement. On the other hand, coir fibers, derived from coconut husks, are rich in cellulose and can be easily processed into nanocellulose, offering a versatile material for various applications. Additionally, coir pith, another by-product of the coir industry, contains cellulose that can be efficiently extracted and converted into nanocellulose, providing a superior platform for new biomaterials. The unique chemical structure of cellulose in coir fibers and pith allows for the production of nanocellulose with enhanced properties, making it a more favorable source for nanocellulose compared to vetiver root.
Does an increase in surface area to volume ration increase cell adhesion and proliferation on scaffolds?
5 answers
Increasing the surface area to volume ratio on scaffolds has been shown to enhance cell adhesion and proliferation. Studies have demonstrated that modifying the surface properties of scaffolds, such as adjusting the surface energy and roughness ratio, can significantly impact cell attachment, growth, and proliferation. Techniques like surface modification with polydopamine or polynorepinephrine have been effective in increasing hydrophilicity and promoting cell adhesion on scaffolds. Additionally, customizing the surface area of 3D printed scaffolds by varying strut diameters has been found to influence cellular proliferation, with smaller diameters leading to increased levels of cell proliferation. Therefore, increasing the surface area to volume ratio through various surface modifications and scaffold designs can indeed enhance cell adhesion and proliferation in tissue engineering applications.
What factors influence the rate of double based propellant decomposition?
5 answers
The rate of double-based propellant decomposition is influenced by various factors. The addition of graphene oxide-copper oxide nanocomposite (GCNC) lowers the activation energy barrier by 18% and reduces the critical ignition temperature, enhancing the decomposition kinetics. Metal complexes of triaminoguanidine-glyoxal polymer (TAGP-Ms) act as energetic burn rate inhibitors, increasing peak temperatures and heat releases, while promoting combustion heat and reducing burning rates. The interaction between double base components and RDX affects thermal stability and decomposition kinetics, with a kinetic compensation effect observed. Aging accelerates decomposition, and the heating rate influences the DSC behavior of propellants. RDX content in double-base propellants affects stability, activation energy, and decomposition mechanism, with 50% RDX content showing optimal performance.

What are reinforcement materials in composites?
5 answers
Reinforcement materials commonly used in composites include high-strength fibers like glass, carbon, aramid, basalt, and others. These fibers are embedded in a matrix, typically a thermoset or thermoplastic polymer, to form composite materials with enhanced properties. The selection of fiber reinforcement type is crucial as it directly impacts the flexural, tensile, and compression strength of the composite material. Unidirectional fiber reinforcement provides strong load resistance in one direction, while randomly oriented fibers offer balanced strength in all directions, albeit at a lower load capacity. Additionally, fiber reinforced polymer (FRP) composites utilize various fibers such as carbon, glass, boron, and aramid, combined with resin matrices to create materials with excellent strength-to-weight ratios and resistance to corrosion.
What are the results of excessive alkali threatment on fibres?
5 answers
Excessive alkali treatment on fibers can lead to detrimental effects on their properties. Studies on various fibers like pineapple leaf, lantung, banana, and sedge have shown that beyond optimal concentrations and immersion times, fibers start to exhibit reductions in mechanical properties, interfacial bonding with matrices, and thermal stability. For instance, in pineapple leaf fibers, concentrations above 6% NaOH resulted in decreased mechanical properties and interlocking with the matrix. Similarly, banana fibers treated with NaOH concentrations beyond 15% showed no further improvement in properties and even exhibited aesthetically unappealing color changes. Additionally, sedge fibers treated with 5% and 10% NaOH damaged the fibers, leading to reductions in crystallinity index and overall fiber integrity.
How can fibres can be classified?
4 answers
Fibers can be classified using various methods such as electrophoresis, dielectrophoresis, chemical treatments, optical microscopy combined with deep learning, spatial similarity, and mesh disc separation. Electrophoresis separates fibers based on diameter and length, while dielectrophoresis efficiently classifies fibers by length due to the dependence of deposition velocity on length. Chemical treatments like fluoropolymer coatings aid in differentiating fibers, enhancing their evidential value. Optical microscopy combined with deep learning automates the detection and classification of wool-fiber mixtures. Spatial similarity-based methods and systems utilizing fiber tracking and clustering contribute to effective fiber classification. Additionally, mesh disc separation techniques with suction and spray nozzles help recover classified content by separating screenings and remnants containing fibers.
Why can radiation be neglected when phase change occurs? give an example for a drying process of organic fibres?
5 answers
Radiation can be neglected during phase change processes due to the specific properties of the materials involved. For instance, in the drying process of organic fibres, the use of a closed vessel with a translucent ceiling allows heat radiation to pass through while blocking ultraviolet rays, aiding in moisture evaporation. Additionally, the impregnation of organic fibres with mineral substances, followed by compaction and drying, results in a structured surface with a durable bond between the coating and fibre surface, enhancing the overall process. Moreover, the incorporation of phase-change composite fibers in building mixes enables the accumulation and release of thermal energy, impacting the heating and cooling rates of hardened plasters under different conditions, showcasing the significance of phase-change materials in thermal regulation.
