The purpose of this research was to comprehensively evaluate the performance and emission characteristics of a diesel engine using a novel fuel blend comprising a hybrid nano-emulsified JME-Diesel blend (B20). The fuel blend consisted of a mixture of 50 ppm of ferric oxide (Fe2O3) and Silicon Dioxide (SiO2) nanoparticles. The engine's performance and emissions were investigated under different load conditions ranging from 0 to 100%. This study involved conducting a series of experiments on an engine to evaluate the engine's efficiency (BTE) and fuel consumption (BSFC). Additionally, emissions in exhaust including NOx, CO, HC, and excess O2 were measured to assess the environmental impact of the hybrid nano-emulsified JME-Diesel blend (B20). The results obtained from the experimental investigations revealed that the adding of nano Fe2O3 and SiO2 to the JME-Diesel blend improved the engine's performance and reduced emissions. An increase in the proportion of nanoparticles 50 ppm led to a significant improvement in BTE, while simultaneously reducing BSFC. Regarding emissions, the hybrid nano-emulsified JME-Diesel blend (B20) demonstrated a considerable reduction in CO2, CO, and HC emissions than neat diesel . Notably, the emission reductions were more pronounced as the nanoparticle proportion increased. This indicates the potential of the hybrid nano-emulsified fuel blend to contribute towards environmental sustainability and mitigate the adverse effects of diesel engine emissions. In insinuation, the results demonstrate the promising characteristics of an engine fueled with a hybrid nano-emulsified JME-Diesel blend (B20). The findings suggest that the inclusion of nano Fe2O3 and SiO2 in the fuel blend can enhance engine efficiency while reducing harmful exhaust emissions.

The goal of this investigation was to focus on the viability of synchronous aging of natural product waste with Aspergillus Niger TISTR 3063 co-societies producing ethanol. Additionally noted was how the aging temperature affected the yield of ethanol. Peels from pineapple and banana were used as substrates, and they were prepared by being slashed into little rectangular pieces. A 250 ml Erlenmeyer jar containing glucose was used to mature several bundles of natural product waste as a control. Analysis of the factors involved in the production of organic waste included sugar, pH, TS, vs, debris, moisture, COD, and TKN. In my review, bio ethanol was produced from banana strips and pineapple strips using pretreatment techniques, more specifically, soluble and acidic pretreatment. The process of aging interaction is then used to produce bio-ethanol. However, the production of bioethanol from food crops needs to be regulated to ensure food security and requires line-by-line analysis to move potential financial and environmental risks. Utilizing Plan Master Programming version 13, determine whether the nature of the bioethanol has changed after synthesis.Using plan master programming, it is possible to see how the item ethanol is being streamlined. Plot the chart for the item's actual and predicted values, one component diagram, and 3D surface. The fuel qualities of the bioethanol that was given were thought to be comparable to those of diesel fuel, and they also complied with ASTM regulations.

Pozzolanic material and a chemical admixture have been used in the current investigation; Nano Biomass Silica (NBS) and Poly-Carboxylate Ether (PCE). NBS produces 20% of the 590 million tonnes of paddy produced globally. Amorphous silica, a mineral component used in concrete, is present in sizable levels in these by-products (NBS). A binary and ternary of NBS with partial replacement of Ordinary Portland Cement (OPC) and the addition of PCE with varying dosage by weight of cement were used. This study's goal is to determine how they affect paste Setting time (ST) and Standard consistency (SC), and hydration temperature evaluation conducted in hot weather with various percentage at NBS from 6, 12 and 18% and PCE with varying dosage from 0.8, 0.9 and 1%. The chemical bond & structure of pozzolanic and chemical admixture in the FTIR were analysed. While PCE showed very little impact on consistency, higher w/b ratios with higher NBS levels were required for the maintenance of OPC-NBS paste consistency standards. The Initial setting time (IST) & Final setting time (FST) for binary OPC-NBS pastes significantly raise to 6% NBS, followed by a decrease at 12% and 18% NBS. However, for OPC-PCE pastes, the IST increased to 0.8%PCE followed by decrease at 0.9% and 1% PCE. In cement paste, PCE can be added as an additive, but the FST increases with an increase in the PCE percentage. At the same time, the mineral admixtures NBS can be used as a cement paste to decrease the FST and also reduce agricultural waste. NBS will effectively use silica ash as a microstructure filler as an additive in manufacturing to produce a certain form of cement with specific IST and FST, in particular for the sustainability of building materials and in hot weather.

By using a hybrid solar mineral water production setup to turn sea water into mineral water, this research intends to provide a comprehensive solution to the human need for drinking water. Before feeding seawater into the solar still, it also applies the proper pretreatment. In order to increase the rate of evaporation, this research maintains a thin layer of water. It also chooses or optimises the best PCM for night production and supports climatic fluctuations during day production. It chooses and refines the best absorber black coating for the basin in order to improve the quality and longevity of the absorption process. This article adapts the proper post treatment for fresh water to provide mineral water and has the necessary alterations to utilise the hybrid system anywhere there is feed water, if necessary. The computer-integrated data logger is used to properly infer real-time measurements. As a result, the hybrid effort increased both the yield of fresh water and the drinking water's quality. The highest yield was 6.273 kg per square metre per day in the winter and 9.715 kg per square metre per day in the summer. The design of the solar still with multiple trays, solar disc emphasis on the solar still, and cover cooling technique shall be supplemented the additional yield of fresh water from the sea water can further improve the system.
