Rajiv Gandhi Institute of Petroleum Technology (RGIPT), in Jais, Amethi (formerly in Raebareli), Uttar Pradesh, India, is a training and education institute focusing on the petroleum industry. It was formally opened in July 2008.It has been accorded the Institute of National Importance status and a governance structure similar to that available to IITs. It admits undergraduate students from the rank list of students who have qualified Joint Entrance Examination – Advanced (JEE Advanced) Examination.
This paper is based on the results of petrological and geochemical studies carried out on coal samples taken from Lower Gondwana coal-bearing horizons (Barakar Formation) of Sohagpur coalfield of Burhar-Amalai sub-basin of Madhya Pradesh (India). The study also shows that the coals of this basin are striated in nature and are dominated by ‘striated, striated dim’ and ‘striated bright’ components. Moreover, vitrinite (mean 33.1 vol
The Himalayas comprise a wide diversity of rock types with variations in the rock mass’s inherent textural characteristics and structural features. This terrain has been explored frequently for numerous rock engineering projects and is witnessing progressive infrastructure development owing to the potential of tourism and the prospect of producing hydroelectricity. Moreover, the instability of rock masses continues to be a cause of concern in the region. Therefore, the insight into the physico-mechanical properties of the Himalayan rocks has significant implications for determining appropriate support systems and ensuring cost-effective, sustainable and efficient construction of various structures such as dams, bridges, underground openings, or rock excavations and for optimising the drilling and blasting parameters. Over the period, several researchers have evaluated the engineering properties of the Himalayan rocks from different perspectives. However, a brief review of the variation of rock properties for different tectonostratigraphic zones through the available literature is somewhat elusive to date. In line with this, the present study focused on an in-depth analysis of this issue by scrutinising and assessing accessible research articles on the engineering characteristics of Himalayan rocks. Secondly, possible avenues for further investigations have been presented to provide insight to researchers by identifying the scope and potential of future research in the Himalayan region. This review article can serve as a reference for geotechnical practitioners seeking insights into the properties of rock materials across various rock types in the region.
Plastic waste accumulation poses mounting environmental threats globally. Upcycling these materials into valuable nanomaterials, like graphene nanosheets (GNs), provides a promising sustainability solution. This study synthesized GNs from plastic waste and evaluated their efficacy as drilling fluid additives. Various analytical techniques characterized the produced GNs. Experiments examined the impact of 0.05–0.44 wt
Biofuels have gained increased attention in the context of sustainable development and the pursuit of net-zero emission goals amidst the ongoing global energy crisis. Consequently, there is a growing exploration of biobased substitutes for sustainable feedstocks to produce biomass-based bioenergy. The primary focus has been on fourth-generation (4G) biodiesel, which stands out as a promising renewable energy resource with significant potential as a new alternative fuel. This interest is coupled with a focus on various biological processes, including genetic modification and engineering strategies, aimed at enhancing the accumulation of lipids, alcohols, hydrocarbons, polysaccharides, and other energy storage compounds in photosynthetic organisms such as microalgae, yeast, and bacteria. This review comprehensively covers the entire biological process of producing 4G biodiesel, including genetic engineering or stimulation of genes. Additionally, it encompasses various aspects, such as feedstock availability, chemical compositions, market analysis, anticipated demand, and program policy. Furthermore, it examines potential avenues of a biological approach, such as genetic engineering, which can improve the production of 4G biodiesel and different elements that influence product yield and quality, including feedstock-related properties and different system conditions. The review also outlines the future availability of 4G biodiesel and hydrotreated vegetable oil (HVO), emphasizing their potential contributions to meeting the sustainable development goals.
Research on transition metal oxides as alternative anodes for Li-and Na-ion batteries has become increasingly important due to the limitations associated with conventional graphite and hard carbon anodes, respectively In this paper, we explore the impact of TiO2 shell thickness on the electrochemical performance of CuO@TiO2 core-shell nanoparticles. Out of the five different compositions with varied shell thickness, the material synthesized with 1.5 mL TTIP showed the optimum result as anode for Lithium-ion Batteries (LIBs) and Sodium-ion Batteries (SIBs). For optimum sample the charging/discharging capacity after 100 cycles has been found to be 763.2 mAh g-1/775.8 mAh g-1 at 100 mA g-1 current density for LIBs. Similarly, for SIBs, the obtained charging/discharging capacity is 83.6 mAh g-1/85.8 mAh g-1 at current density of 50 mA g-1 after 100 cycles. A tentative working mechanism based on the multi-valency of CuO@TiO2 has also been proposed using X-ray diffraction, electron microscopy, and XPS studies. To the best of our knowledge, this is the first report on effect of variation of shell thickness of core shell CuO@TiO2 which results in improved electrochemical properties of CuO@TiO2.
