Recent Advances on the Role of Cu-Nanoparticles in the Organic Transformations
Abstract: Copper nanoparticles explored the most useful class of heterogeneous catalyst in various chemical transformations. Copper nanoparticles has attracted much more attention because of its promising activity, high atom economy, better yield, shorter reaction times, inexpensive, recyclability, low catalyst loading. These approaches open new possibilities in, click reactions, C-N and C-S cross coupling reaction, fixation of CO2, KA3 and A3 coupling, aziridine ring opening reactions. This review covers some useful organic …

Recent advances in utilization of wide band gap metal oxides for photocatalysis of organic waste
Abstract: Water cleaning has become a major challenge in the current scenario with huge amounts of industrial wastes being accumulated in the water bodies over the years. Traditional chemical, physical and biological processes for treating wastewater containing textile dye have disadvantages such as high cost, high energy requirement and generates secondary pollution during treatment process. The progressive oxidation processes technology has been appealing growing attention for the decomposition of organic dyes. …

Plant-drive Waste Fiber Reinforced Thermoplastic Composites: Modification of Fiber Surface Treatment
Abstract: Plant fibers are being utilized more frequently to create polymer composite parts for the aerospace, construction, and automotive industries. The increased awareness of the toxicity of synthetic fibers is what has caused a rise in the use of plant fibers across a variety of industries. It is crucial to emphasize that "Earth needs humans, not humans need earth," hence decision-makers and researchers are working to replace conventional materials with eco-friendly …

Analyzing the Effect of Rice Husk Ash & Quartz Powder on Mechanical Properties of Polypropylene Fiber Based Concrete Using Regression Analysis
Abstract: Several works were identified with sustainable development have uplifted the improvement of composite binders incorporating Portland cement, industrial, agricultural by- products and partial substitutions to aggregates. One of the most adverse effects of using cement is the emission of CO2 into atmosphere during production and it can be reduced with the effective use of cementitious materials. Several efforts were attempted to make use of supplementary cementitious materials to enhance the …

A Review on Layer Formation Studies in Selective Laser Melting of Steel Powders and Thin Wall Parts Using Pulse Shaping
Abstract: This paper advances the conclusions of the selective laser melting (SLM) of tool steel and stainless steel powders. The characteristic feature is the melting of single layers in deep powder beds by a continuous CO2 laser. First, effect of development parameters on the surface roughness for each material is examined. Based on these results combined with visual observation of the solidified tracks, the question is then discussed as how the …

The Influence of Hexanol and Methyl Acetate as Oxygenated Additives with Diesel Fuel in a Diesel Engine Generator
Abstract: Diesel engines play a vital role in all the major sectors (such as transportation and industrial) due to their high efficiency, durability, reliability and low operating cost. At the same time, they are considered as one of the biggest contributors of environmental pollution by releasing enormous amount of toxic gases to atmosphere (such as NOx, HC, CO2 and PM). Emissions from transport, especially motor vehicles, increase the level of gases …

Production of Composite Biodiesel from Pongamia & Simarouba oil and Comparison of Performance of Composite Biodiesel with Diesel
Abstract: Pongamia oil and simarouba oil are mixed in equal volume to prepare the composite oil. The composite oil is processed through two stage transesterification process to produce composite biodiesel. The composite biodiesel blends are prepared by mixing neat biodiesel with diesel by 5%, 10% and 20% volume respectively. The engine control factors viz., injection pressure, injection timing and fuel preheating temperature are considered for evaluating the performance of composite biodiesel …

Methods of Cardiac Output Monitoring
Abstract: Cardiac output is the primary compensatory mechanism that responds to an oxygenation challenge. The determination of blood flow, i.e. cardiac output, is an integral part of hemodynamic monitoring. This is a review on methods of cardiac output monitoring. Minimally invasive cardiac output monitors have varying degrees of ‘invasiveness’ with some being totally non-invasive and others only marginally less invasive than a pulmonary artery catheter (PAC). All minimally invasive cardiac output …
