In this study Tetranitro Zinc (II) Phthalocyanine is synthesized via base catalysis before the product is characterized via IR, 1H NMR &amp; UV-Vis analysis. Assessing the desirability of the Tetranitro Zinc (II) Phthalocyanine as a solar organic semiconducting dye in DSSCs and LSCs. The desirability is assessed by novel computational DFT calculations, of the aggregation binding mode to deduce if Aggregation-Caused Quenching (ACQ) is occurring in the aggregated sample. ACQ is known to reduce DSSCs and LSCs generation of useful photo-active current. Aggregation-Caused Quenching (ACQ) is mathematically indicated in Phthalocyanine aggregation and Tetranitro Zinc (II) Phthalocyanine’s desirability is assessed for further use in DSSCs and LSCs. </span></p> 2022-01-12T00:00:00+00:00 Copyright (c) 2022 Connor Atkinson (Author) Weight Reduction in Aluminum Metal Matrix Composite by Adding Copper Slag as A Reinforcement 2022-02-12T05:17:14+00:00 Rakesh G <p>The aim of this paper is to fabricate aluminum metal matrix composite which should have less weight than aluminum and better mechanical property. Copper slag (waste from copper extraction) is taken as a reinforcement and the metal matrix composite of aluminum 95% and copper slag 5% was fabricated using the stir casting method. The particle distribution is verified by an optical microscope. Mechanical properties of the composite were calculated by conducting the tensile test, impact test, and hardness test, and the calculated values are compared with the theoretical value and aluminum. The chemical composition of the copper slag is tested and checked with literature values. The tensile strength, hardness, and impact strength of the composite is increased when compared with base metal aluminum but the weight of the composite is less.</p> 2022-06-01T00:00:00+00:00 Copyright (c) 2022 Rakesh G (Author) Comparative Study on the Mechanical Properties of Weft Knitted and Warp Fabric Reinforced Composites 2021-10-10T10:23:20+00:00 Alhayat Getu TEMESGEN Omprakash Sahu <p>Knitted fabric composites occupy a special interest in the field of engineering and materials science because of their easy to form complex component and high impact energy absorption. Mechanical tests were carried out in the course, wale and slanting directions of the knitted fabric reinforced composites. The stress-strain curves and failure modes of warp and weft knitted fabrics were investigated and compared. The test results revealed from the composite structure fabricated from warp knitted fabric shown better mechanical properties than weft knitted fabric because of the warp knitted fabric distinct by the process of overlap between the stitches that gave better resistance.</p> 2022-06-02T00:00:00+00:00 Copyright (c) 2022 Alhayat Getu TEMESGEN, Omprakash Sahu (Author) Analytical and Experimental Study on Flexural Behavior of Beam-column Joint with Addition of Polypropylene Fibers 2021-05-05T17:50:03+00:00 P Dhanabal P Narendra Reddy K S Sushmitha <p class="Abstract"><span lang="EN-US">Key scope of this research is evaluation of actions of beam to column joints under the impact load acting on it. The beam-column joints, a common area between frame beams and columns. It is the most critical zone to ensure the global response of such momentary resistance structures. Several approaches have been attempted over the years by many civil engineers and practitioners to improve the deficiently thorough joint in between beam and column. The highest bending moment and shear forces in the framed structures are at the junction area. As a result, that joint between beam and column is one of a collapse zone. Joint in outer is more important among the beam-column joints. The effect may be caused by a weight falling on the design object or possibly falling off the design object and hitting the hard surface. In this work, an emphasis has been made to understand the joint vulnerability against impact loads and its behavior is analyzed using the ANSYS software. From this experimental program observed that, impact resistance in RCC beam to column joints can be improved by improving stiffness by added polypropylene fibers and energy absorption can also be improved.</span></p> 2022-06-02T00:00:00+00:00 Copyright (c) 2022 P Dhanabal (Author); P Narendra Reddy; K S Sushmitha (Author)
