In this era, composite materials made of natural fibers are gaining the attention and interest of researchers, scientists, and engineers due to their impeccable features in contrast to synthetic fibers. Composite materials can be easily modeled and produced in various dissimilar forms as per the need. In this study, four different composite samples were prepared using three distinct fibers; two natural-banana (B) and sisal (S) and one synthetic-glass (G), by varying the weight percentage of banana and sisal. For each sample, the stacking sequence of the fibers are (B-G-S-B), (S-B-G-S), (G-B-B-S), and (B-S-S-G), oriented at (900,+450,−450,900) and put through a uniform point load. So, a total of sixteen composite samples were evaluated for directional deformations, stresses, and rotations using ANSYS Mechanical APDL 15.0. The outcome obtained showed that the arrangement of fibers in the sequence sisal-banana-glass-sisal (S-B-G-S) at different orientations is superior in terms of toughness and distortion resistance in contrast to all the sixteen arrangements.

Green composites made up of natural fibers are being immensely used in the last few decades due to their enhanced properties and environmental aspects. The boon of natural fibers is their uninterrupted supply, non-allergic and decomposable nature. Many types of natural fibers like jute, bamboo, hemp, flax, pineapple, coir, luffa, kenaf, sisal, wood fiber, and many more had been explored for their various uses. Natural fibers are being used over manufactured fibers as strengthening for plastic and polymeric materials owing to their low cost and renewable aspects. Banana fiber is one of the copious available material which had been studied for its physicomechanical and chemical properties. A detailed study of these properties will bring out rational and worthy uses of banana fiber for various applications. This paper discusses in detail the properties, utilization, extraction, limitations, and applications of banana leaf fibers and their composites.

Biodiversity is a boon for reinforcement of sustainability and innovation for betterment of society via transformation of scientific temper. Nature has consciousness and invincible strength to bio diversified plants against protection from unforeseen turbulence is observed by researchers. Natural bamboo is a type of Bio composites found in tropical region has strength to weight ratio and aesthetics valuation more than alloy steels hence it is useful in ultra-luxurious segment of society. The purpose of the paper is to elaborate mechanism and mechanics of natural bamboo materials explicitly for determination of micro/macro rupture of fibre matrix adhesion subjected to severe shearing as efficient natural strength of tensile strength and bending strength inbuilt with bamboo by nature and failure mode is conventional in plane twisting of composite culms. The paper is useful for researchers focusing on innovation and green technology for achievement of sustainable development goals.

During neuronal development, local mRNA translation is required for axon guidance and synaptogenesis, and dysregulation of this process contributes to multiple neurodevelopmental and cognitive disorders. However, regulation of local protein synthesis in developing axons remains poorly understood. Here, we uncover a novel role for the actin-regulatory protein Mena in the formation of a ribonucleoprotein complex that involves the RNA-binding proteins HnrnpK and PCBP1 and regulates local translation of specific mRNAs in developing axons. We find that translation of dyrk1a, a Down syndrome- and autism spectrum disorders-related gene, is dependent on Mena, both in steady-state conditions and upon BDNF stimulation. We identify hundreds of additional mRNAs that associate with the Mena complex, suggesting that it plays broader role(s) in post-transcriptional gene regulation. Our work establishes a dual role for Mena in neurons, providing a potential link between regulation of actin dynamics and local translation.
