<p>In this study, milk waste water will be extracted, transformed into Lipolytic microorganism’s biodiesel (LMD) using transesterification, and tested for appropriateness as an alternative, sustainable, renewable source for IC engines. The properties of the created blends of biodiesel were investigated and compared to those of conventional diesel. The outcomes demonstrated that the fuel's fundamental characteristics are discussed with neat diesel. Investigated are the operation, combustion, and exhaust gas analysis of a test engine running on LMD. The studies involve running different biodiesel-diesel blends (B10, B20, B30, B40, B50, and B80) at varying loads (0, 25, 50, 75, and 100%) in a single-cylinder direct-injection diesel engine at a constant speed and comparing the results to the benchmark diesel. The values of break thermal efficiency(BTE) was decreased by 0.59, 0.68, 1.30 and 2.98% respectively for the blends of 10, 20, 30 and 50% of biodiesel mixing. The brake specific energy consumption (BSEC) is decreased by 0.1, 0.3, 0.44, and 0.77%. Any biodiesel-diesel combination reduces exhaust gas pollutants. At maximum load, the values of emissions like CO, HC, and smoke opacities of B30 decreased by 12.1%,3.94%, and 11% when compared to standard diesel. However, as per the analysis biodiesel of LMD is a potential alternative fuel that doesn't require significant alterations to be used in I.C engines.</p>

People are using biodiesel in compression ignition engines because it is more environmentally friendly and can be used as a good alternative to diesel. There is a new technology called nanoparticles that can change the way a fuel works. Because waste cooking has a lot of oil in it, it can make biodiesel. To make biodiesel, transesterification was used to turn nonedible oil from waste cooking oil into biodiesel that could be used. Nanoparticles made of titanium oxide were studied by using scanning electron microscopy, transmission electron microscopy, as well as energy dispersive X-ray analysis, among other things. TiO2 nanoparticles are spread out in different amounts in the biodiesel blend. The dosage levels range from 25, 50, 75, and 100 ppm. Tests on how titanium nanoparticles in a waste cooking oil biodiesel blend affect a diesel engine’s performance and how it emits were conducted in this study too. At a steady speed, the engine was used when there was a lot of work to do. Tests show that the WCOME 20 TiO2 100 ppm blend worked well. With the increase in the concentration of nanoparticles, there is an increase in brake thermal efficiency and at the same time, there is a decrease in BSFC. It is also less harmful to the environment than other blends, except for NOx, which does no’t change.

Background: The use of chemical fertilizers and pesticides raises concerns about environmental pollution, health hazards and the destruction of biotic groups that support plant growth. Plant growth-promoting rhizobacteria (PGPR) thrive in the rhizosphere of plants are the auspicious alternative for these chemicals. PGPR plays a critical role in plant growth and development, along with biocontrol activities. Methods: In this present study, two effective microbes, Bradyrhizobium japonicum and Bacillus subtilis were chosen and their ability to produce Indole Acetic acid (IAA) was determined. Optimization of IAA production was carried out in different cultural conditions. Further, in-vitro studies were carried out to analyze the effect of these bacteria on the growth of Vigna radiata. Results: Our investigations showed that both organisms have the potential to produce IAA under standard conditions. IAA production is maximum when using Bradyrhizobium japonicum with the supplement of Carboxymethyl cellulose and yeast extract as C and N source, respectively. L-Tryptophan concentration has a positive effect on production. Further, the application of bacterial cultures has shown more significant improvement in plant growth in terms of root and shoot length and weight of crop material. The current findings recommend that Bradyrhizobium japonicum can be a suitable organism for application as a plant growth promoter.

Countries globally are focusing on alternative fuels to reduce the environmental pollution. An example is biodiesel fuel, which is leading the way to other technologies. In this research, the methyl esters of castor oil were prepared using a two-step transesterification process. The respective properties of the castor oil (Ricinus Communis) biodiesel were estimated using ASTM standards. The effect of performance and emission on diesel engines was noted for four various engine loads (25, 50, 75, and 100%), with two different blends (B5 and B20) and at two different engine speeds (1500 and 2000 rpm). The study determined that B5 and B20 samples at 1500 rpm engine speed obtained the same power, but diesel fuel generated greater control. The power increased at 2000 rpm for B5 samples, but B20 samples, as well as diesel, were almost the same values. In the 40–80% range, load and load values were entirely parallel for each load observed from the engine performance of the brake power in all samples.

The usage of natural fibers has increased recently. They are used to replace synthetic fiber products in aircraft and automobile industries. In this study, natural fibers of bidirectional banyan mat and ramie fabrics are used for reinforcement, and the matrix is an epoxy resin to fabricate composite laminates by traditional hand layup technique at atmospheric temperature mode. Five different sequences of reinforcements are as follows to quantify the effect of thermal stability and mechanical behavior of silane-treated and untreated hybrid composites. The results revealed that silane-treated fabric composite laminates were given enhanced mechanical properties of 7% tensile, 11% flexural, and 9% impact strength compared with untreated fabric composite, and at the same time when the increasing of ramie fabric was given the positive influence of 41% improved tensile strength of 40.7 MPa, 49% improved in flexural strength of 38.9 MPa and negative influence in 57% lower impact strength in sample E and positive value in sample A 21.12 J impact energy absorbed in the hybrid composite. Thermogravimetric analysis (TGA) revealed the thermal stability of the hybrid composite. In sample A, the thermal stability is more than in other samples, and 410°C is required to reduce the mass loss of 25%. The working mass condition of the hybrid composite is up to 3.25 g after it moves to degrade.

Abstract Metal matrix composites are extensively used in aerospace, automobile and other engineering applications as an alternative to a wide range of elements. High strength–weight ratio, durability and high corrosion resistance are benefits of metal matrix composites. The study that exhibits adopts optimal cutting parameters (speed, feed and depth of cut). The initial study is to explore end milling process of alumina (AA6082 with SiC 3% and fly ash 2%) molted metal matrix composite. The technique for order preference by similarity to ideal solution and fuzzy logic for optimizing the cutting parameter values has been utilized in the MMC. The response surface methodology is being used to develop the numerical model between output responses and machining parameters. The second-order regression models are studied through analysis of variance. The experimental investigation exhibits that feed rate is the important factor on response variables.
