“…The fluctuation in the graph might be due to more formation of resin tags, voids and dimples that reduce the ductility due to the poor adhesive forces between resin and fillers. This type of fluctuation in the strength is seen in other neem constituents used in composites [17,18].…”

Natural fillers have received great attention among researchers due their its light weight, high strength, degradability, and eco-friendly behavior. This work is focused on developing a laminate of date palm seed powder and neem gum powder reinforced epoxy resin. Epoxy resin is an excellent thermoset polymer with anoutstanding cost to performance ratio. Date palm seeds have highly competitive properties in improving the mechanical and thermal properties of composites by their good adherence to polymer matrix. Neem gum powder is used as a binder in increasing ratios of 0 %, 10 %, 15 %, 20 %, 25 %, and 30 % to test their strength in different compositions. Date seed powder has been reinforced in decreasing weight percent as 30 %, 25 %, 20 %, 15 %, 10 %, 5 %, and 0 %. The specimens prepared through the compression moulding technique were subjected to various mechanical tests like a tensile test, flexural test, and impact test as per the ASTM standards. Fractography analysis using FESEM (Field Emission Scanning Electron Microscopy) and FT-IR(Fourier Transform Infrared spectroscopy) test have determined the surface characteristics and chemical composition of the samples. The result shows that, by adding neem gum powder in increasing quantities the mechanical properties like tensile and flexural decreases. However, it does not affect the impact strength of the material. A detailed study of their behavior is discussed in this work.

“…The Ch NFRCS and Cp NFRCS showed less percentage of thrombogenicity than the Cs scaffold, which confirms the non-thrombogenic nature of the developed NFRCS. Other factors include hydrophilicity, chemical composition, surface topology, and morphology that influence the surgical sealants' hemolytic potency 57 , 58 .…”

Unmanageable bleeding is one of the significant causes of mortality. Attaining rapid hemostasis ensures subject survivability as a first aid during combats, road accidents, surgeries that reduce mortality. Nanoporous fibers reinforced composite scaffold (NFRCS) developed by a simple hemostatic film-forming composition (HFFC) (as a continuous phase) can trigger and intensify hemostasis. NFRCS developed was based on the dragonfly wing structure's structural design. Dragonfly wing structure consists of cross-veins and longitudinal wing veins inter-connected with wing membrane to maintain the microstructural integrity. The HFFC uniformly surface coats the fibers with nano thickness film and interconnects the randomly distributed cotton gauge (Ct) (dispersed phase), resulting in the formation of a nanoporous structure. Integrating continuous and dispersed phases reduce the product cost by ten times that of marketed products. The modified NFRCS (tampon or wrist band) can be used for various biomedical applications. The in vivo studies conclude that the developed Cp NFRCS triggers and intensifies the coagulation process at the application site. The NFRCS could regulate the microenvironment and act at the cellular level due to its nanoporous structure, which resulted in better wound healing in the excision wound model.
