This by-product of date processing industries could be regarded as an excellent source of dietary fiber with interesting technological functionality and many beneficial effects on human health.
The dissolution rate constant for a fiber may be extracted from the decrease in long fiber diameter observed in certain intratracheal instillation experiments or from the observed long fiber retention in short-term biopersistence studies.
An evaluation of the recovered samples found that the fibers appear to have retained good properties and characteristics and are suitable for short fiber applications.
The decrease in bond strength after TML suggests that retention of fiber posts may be reduced after clinical function.
The fiber scaffolds also have good biocompatibility, as revealed by in vitro cytotoxicity experiments.
Results show that the excellent characteristics of the raw fiber were still remained after modification although the crystallinity of the modified fiber decreased.

What is the density of a rubber belt?
5 answers
The density of a rubber belt can vary depending on its composition and structure. Different rubber compositions for belts have been studied for various applications. For instance, a rubber composition for an industrial belt includes specific syndiotactic-1,2-polybutadiene crystal fibers with an average fiber length of 200 nm or less. In the context of agricultural tractors, soil compaction studies comparing rubber belt tracks and tires showed that bulk density resulting from the rubber belt track was numerically less than that from the tire, indicating potential differences in compaction levels. Additionally, a rubber composition for a conveyor belt aimed at achieving energy savings and dimensional stability contains carbon black with specific properties in defined proportions. These variations in rubber compositions and applications contribute to different densities in rubber belts.
Which phase of calcium phosphate does show both osteoconductive and osteoinductive properties?
5 answers
The phase of calcium phosphate that exhibits both osteoconductive and osteoinductive properties is biphasic calcium phosphate (BCP). BCP is recognized as a synthetic bone graft material with osteoinductive potential, making it beneficial for bone repair applications. Studies have shown that BCP can enhance bone healing responses and promote bone regeneration by interacting with biological processes such as immune responses, osteoclastogenesis, and osteoblast activity. Additionally, research has highlighted the importance of optimizing the composition of BCP by incorporating trace elements like lithium ions to further enhance its osteogenic properties. Proper doping levels of lithium ions in BCP have been found to improve crystal stabilization and biological responses, making BCP an effective material for bone tissue engineering.

Why increasing the pp fiber content higher than 2% cause decreasing in UCS value?
4 answers
Increasing the polypropylene (PP) fiber content beyond 2% can lead to a decrease in the unconfined compressive strength (UCS) value due to various factors. Research on microcellular wood fiber reinforced polypropylene composites indicates that the mechanical properties, including tensile strength, are influenced by the fiber content. Additionally, in ultra-high-performance concrete (UHPC) studies, it was found that the explosive spalling resistance of the hybrid fiber-reinforced UHPC increases with the increase of the PP fiber content. Therefore, a higher PP fiber content may alter the composite's structure, affecting its mechanical properties and overall strength, leading to a decrease in UCS value.
