Preparation and Performance Evaluation of LDPE/Rice Starch Blend Composites by Extrusion Method
Abstract: Discarding synthetic polymers such as low-density polyethylene (LDPE) used in food packaging ingredients is today considered a serious ecological threat because they are non-decomposable. The goal of this article is to create a decomposable polymer by incorporating a bio-polymer (starch) into its polymeric matrix. This article focuses on the preparation and characterization of rice starch (RS)-mixed LDPE decomposable polymer. In the first study, the effect of variability of RS content …

Physico-Mechanical Performance of Waste Plant Fiber Reinforced Thermoplastic Composites for Automotive Applications
Abstract: To maximize the interfacial bond strength, it is necessary to investigate the direct relationship between the degree of fiber-matrix adhesion and the mechanical and fracture behavior of composites. In this work, the strength of the interfacial bond between polypropylene (PP) and waste plant fiber (Dharose plant fiber, DF) that have been subjected to ultraviolet radiation (UV) was established. By using hot press molding, unidirectional composites of PP with dharose plant …

UNIT OPERATIONS IN CHEMICAL INDUSTRIES
Abstract: The unit operation like distillation, absorption, evaporation, filtration, drying, etc. are most important factors. Distillation is a purification method for liquids and can separate components of a mixture if they have significantly different boiling points. Absorption is a physical or chemical phenomenon. Evaporation can be defined as the process where liquid is transformed into a gaseous state. Evaporation can occur only when water is available. Drying is an important unit …

Deforestation: Causes and Consequences of the Global Crisis
Abstract: Climate change is unavoidable due to the dynamic character of global ecosystems. The reasons of these environmental changes are both man-made and natural. Human activities have always had an impact on the environment. As economic activity and population expansion have risen to the point that they can no longer be disregarded or seen in isolation, the consequences of mankind just on environment could no longer be ignored or examined in …

Pitaya Cactus Endophytic Bacteria a Sustainable Option to Reduce and Optimize NH4NO3 in Phaseolus vulgaris
Abstract: The Phaseolus vulgaris crop demands nitrogen fertilizer as NH4NO3 for healthy growth. However, the application of NH4NO3 not uptaken by plant roots, generates N2O, a gas that contributes to the greenhouse effect besides loss of soil fertility; a sustainable option is to reduce up to 50% and to optimize it by inoculating P. vulgaris seeds with genera and species of plant growth promoting endophytic bacteria isolated from a desert xerophyte …

Chemical Synthesis and Industrial Applications of Catechu
Abstract: Kattha is acquired by crystallization in cold from the water extractives of the heartwood of Acacia catechu. The main constituents of the red heartwood are catechin and catechu tannic acid along with small proportion of brown coloring matter. It also contains tannin, flavotannin, gallotannin, hloratannin etc. (+)-Catechin is a constituent, which decreases the action of some hormones; hence “tyronorman” injected with thyroxin terminates the upsurge in basal metabolism. It has …

The Improvement of Polyvinyl Chloride Synthesis Using Different Approaches
Abstract: Polyvinyl chloride (PVC) is produced by the polymerization of the vinyl chloride monomer either by direct chlorination of olefins or by addition of hydrogen chloride to acetylene. The polymerization conditions are: heat, peroxides or oxidizing agents with basic structure as -CH2CHCl.CHCl-CH2.CHCl-. Polyvinyl chloride is a thermoplastic and its plasticity can be increased by incorporating ‘plasticizers’ of relatively low molecular weight organic materials during molding or extrusion. PVC has high hardness …

Several Phases of Binary Liquid Mixture
Abstract: The system’s overall composition, heat, and stress can all be changed independently. Instead of using parameters like the coordinates of a three-dimensional phase diagram, we often generate a twodimensional phase transformation that is either a thermal diagram at a specified pressure or its composition graph at a fixed temperature. The location of the system points on one of these diagrams correlates to a certain heat, stress, and normal phenomenon. As …
