What is the best way to make an aerogel blanket?4 answersThe best way to make an aerogel blanket is by impregnating a catalyzed sol into a blanket substrate and allowing it to remain in the impregnation tank for a specific time to control flowability and achieve a viscosity that enables easy injection into the blanket. This method ensures uniform formation of aerogel inside the blanket, improving the uniformity of pore structure and insulation performance. It also reduces the loss of raw material, minimizes processing problems, and decreases dust generation. Another approach involves using a bobbin on which the blanket is wound, a gelation tank, a drive member to rotate the bobbin, and a silica sol supply member to inject silica sol into the gelation tank and impregnate it into the blanket. This method simplifies manufacturing equipment, improves efficiency, and enhances thermal conductivity by uniformly forming aerogel in the blanket substrate.
How to calculate the graphene oxide sheet size using TEM?5 answersThe size of graphene oxide (GO) sheets can be calculated using transmission electron microscopy (TEM) by following a few steps.

4 answers
Fibers can reduce strength but enhance modulus in polymers due to various factors. The increase in modulus is attributed to improved stress transfer between load-bearing elements in the fibers after polymer infiltration, leading to up to a 50% increase in specific modulus. On the other hand, the reduction in strength can be linked to defects at the ends of microfibrils, which act as mechanically weak areas in the fibrous material, drastically depressing the strength as they fail when strain concentration reaches their limit, leading to microcrack growth and bulk fracture. Additionally, the presence of short fibers in polymer composites can increase tensile strain and strength due to increased microcracking, fiber debonding, and energy absorption mechanisms, ultimately enhancing fracture strain in the composite material.Why does D'peak appear in multi wall cnt's raman?
5 answers
The appearance of the D' peak in multi-walled carbon nanotubes (MWCNTs) in Raman spectroscopy can be attributed to the modification induced by acid treatments, such as HCl, HNO3, and H2SO4, commonly used in purification processes. These treatments lead to surface functionalization and intercalation of the walls, altering the electronic properties of MWCNTs. The acid treatments increase the number of defects in the graphitic structure of MWCNTs, resulting in the modification of typical Raman bands like the disorder band (D band), graphite band (G band), and two-phonon second-order Raman band (G' band). The broadening effect on the G' band's line shape and the emergence of an additional peak are indicative of the enhanced defect presence in the MWCNTs due to the acid treatments.Does the surface morphology of the scaffold directly affect cell morphology?
9 answers
The surface morphology of scaffolds plays a crucial role in influencing cell morphology, as evidenced by a comprehensive analysis of recent studies. Research has shown that the physical and chemical properties of scaffold surfaces, including their topography and roughness, significantly impact cell adhesion, proliferation, differentiation, and migration. For instance, modifications in scaffold surface morphology through treatments such as phosphate buffered saline (PBS) and polyethyleneimine (PEI) coatings have been observed to affect cellular responses, including cell attachment and elongation. Similarly, the creation of 3D scaffolds with tunable surface morphology has been linked to enhanced cell activity, such as increased alkaline phosphatase activity in preosteoblasts, suggesting a potential role in early cell differentiation. Moreover, the introduction of nanopores and roughness on fiber surfaces of electrospun scaffolds has been associated with improved proliferation and adhesion of cells, indicating that topographical features can significantly influence cell-scaffold interactions. The geometry of scaffolds, such as those based on triply periodic minimal surfaces, has also been found to favor cell attachment and proliferation, further underscoring the importance of scaffold design in cellular behavior. Additionally, the mimicry of anatomical features in scaffold design has been shown to induce specific migratory and morphological responses in neural stem cells, highlighting the dependency of cell biological responses on topographical context. Research into macro-patterns on scaffold surfaces has revealed that even larger structures, exceeding cell diameters, can influence cell morphology and function, such as osteogenic differentiation in dental pulp stem cells. The development of 3D printed polymer scaffolds with micro-/nanosurface pores has demonstrated the potential of topography to direct stem cell differentiation. Furthermore, the design of scaffold structures, including pore sizes and the presence of hydrogels, has been found to impact cellular morphology and the formation of spheroids in glioblastoma models. This body of evidence collectively supports the conclusion that the surface morphology of scaffolds directly affects cell morphology, offering pathways to tailor scaffold designs for specific tissue engineering applications.How to make efficient cell for PEFC.?
