Gentiana kurroo Royle is an endangered bitter medicinal plant of the Indian subcontinent region. This medicinal plant mainly grows in Kashmir, Himachal Pradesh, and North-west Himalayas. Native people frequently use the medicinal plant’s root and rhizome for various local remedies. The leaf and root samples of the plant were studied for their phytochemicals screening and antibacterial and antioxidant properties. The methanolic root extract as a comparison to methanolic leaf extract was detected with high concentration of phytochemicals like alkaloids, flavonoids, saponins, phenol, glycosides whereas, other phytochemicals like carbohydrates, tannins, and terpenoids showed equal concentration in methanolic root and leaf extracts. In antibacterial study, the methanolic root extract was found to exhibit a maximum zone of inhibition (33 ± 1) against E.fecalis and minimum zone (17 ± 2) against E. coli. The methanolic leaf extract showed a maximum zone of inhibition (31 ± 1) against E. fecalis and a minimum zone (18 ± 2) against K. pneumonia. The antioxidant activity of G.kurroo revealed that the methanolic extracts of root as compared to the methanolic extract of leaves showed comparatively high antioxidant activity and this is due to the presence of high phenol and flavonoid content.

It is critical to increase the value of life in rural areas by developing power from renewable sources or expanding the grid. The extension of the national grid or off-grid systems depends on location, geography, population, distance from grid point, and land size. Since grid connections are not always available or feasible, off-grid rural electrification systems using renewable energy sources (RES) have become unavoidable. An alternative to costly grid extensions in remote areas of the world is a hybrid combination of renewable energy technologies. This review paper discusses renewable energy sources that can generate electricity for residential and commercial.

Using various Sodium hydroxide (NaOH) concentrations (0, 1, 2, and 3%), we studied the alkaline pretreatment of microalgal biomass from the blue-green alga Nostochopsis lobatus in this work. In this pretreatment stage, the entrapped polysaccharides found within the microalgae cell walls are broken down to form fermentable subunits. The selected pretreatment procedure (2% NaOH) was then followed by enzymatic saccharification for the generation of bioethanol. This pretreatment step aims to release and break down entrapped polysaccharides in the microalgae cell walls into fermentable subunits. The best result of sugars after enzyme hydrolysis was obtained in total and reducing sugars 210.22 and 98.54 g/L, respectively. In addition, Saccharomyces cerevisiae was used to ferment the hydrolysate; the highest ethanol yield was 14 g/L by 48 hours of fermentation. The alkaline pretreatment method was a promising option for pretreating microalgal biomass for bioethanol production.

For many years, dye-sensitized sunlight cells (DSSC), which are feasible and have significant potential to harvest and convert light into renewable energy, have been the subject of serious research. DSSC is a great alternative for low-cost solar panels due to its simplicity in fabrication and acceptable efficiency. While synthetic dyes can produce higher efficiency, their production costs and complexity in synthesizing toxic chemicals that are harmful to the environment, people, and the environment present another problem. Therefore, several studies have focused on natural dyes extracted from plants (chlorophyll-anthocyanin, flavonoid and carotenoid) because of their advantages such as high absorption, low cost, no toxicity, eco-friendly and easy extraction. This review also highlights the development of dye-sensitized sun cells by using natural dyes as photosensitizers.

The new urbanization policy emphasizes ecosystem friendliness. However, there is little research on new urbanization's effect on the ecological environment. This paper builds the LMDI model to decompose the ecological environment into three aspects: green area, wastewater discharge, and industrial solid waste production, to analyze the urbanization driving effect of Fujian Province in 2011-2018. The results show that the green area will increase due to economic-driven and urbanization-driven influences. Land-use-driven will cut down Wastewater discharge and waste generation. Among them, the economic-driven and land-use-driven have opposite effects.

A successful drilling operation is heavily dependent on the effectiveness of the drilling fluid's design in use. This study attempts to evaluate the rheological and filtration properties of water-based drilling mud (WBDM) upon the addition of Stearyl Acrylate-Behenyl Acrylate (SABA) copolymer, silicon dioxide (SiO2), and nickel (III) oxide (Ni2O3) nanoparticles. This SABA copolymer-nanofluid was prepared by dissolving the nanofluid in a SABA polymer solution and homogenizing it using ultrasonication. The properties were studied using mud balance, viscometer, and low-pressure low-temperature (LPLT) filter press. The rheological and filtration properties of SABA copolymer were found to imply that it could improve drilling fluid performance. However, the addition of nanoparticles gave a better performance of rheological and filtration properties on WBDM. SABA copolymer with 5000 ppm concentration shows the best performance due to showing the highest viscosity compared to basic drilling fluid. Also, the addition of 800 ppm of Ni2O3 concentration into 5000 ppm of SABA shows the lowest fluid losses. The experimental results indicate that SABA copolymer shows a great potential application and the addition of nanoparticles shows that nanotechnology has a lot of potentials to improve WBM performance

The mushroom cultivation industry in Malaysia is one of the fastest growing agricultural sectors due to its high return value and low production cost. With the Malaysian government forecasting an RM300 million worth of mushroom exporting by 2020, demand for high-quality mushrooms would rise. Commercially grown mushrooms in Malaysia include Pleurotus ostreatus, Pleurotus djamor, Pleurotus eryngii, and Schizophyllum commune. The mushroom cultivating technique is critical to achieving large yields. More mushrooms can be harvested in less time by employing Effective Microbes (EM) as a yield performance booster. However, EM is not yet commercially accessible, despite the fact that numerous potential EM exist, including dominant bacteria from mushroom production, bacteria bioinoculant, and anti-listerial agent. Furthermore, the EM activator found inside the substrate represents another yet-to-be-commercialized yield performance booster. Several possible EM activators, including as dairy wastewater, rice husk biochar, and tea compost, can be transformed from industrial waste with a steady increase in industrial waste. This paper reviewed the potential of EM in the mushroom cultivation industry. Additionally, the potential EM activator and how it enhances the mushroom yield performance is as well summarized.

Due to low-temperature circumstances, precipitation and paraffin wax deposition in manufacturing pipes and transportation tubes from offshore to onshore are significant challenges in the oil and gas sector. It may cause a reduction in output, a shutdown, pipeline blockage, and increased fluid viscosity. The most often used method for resolving this problem is to inject a wax inhibitor into the channel. Most current studies about paraffin wax are disseminated in literary works or exist as tacit knowledge in professional crania. This review research aims to exchange information and fulfil the deficits caused by providing a complete overview of the chemistry of paraffin wax precipitation and accumulation and causes, processes, and detection. It also discusses the overall impacts of paraffin wax deposition, how to deal with it, and several cleaning options. It also includes a conclusion and beneficial tips.

Palm oil is one of the important raw materials in the oleochemical industry for downstream expansion and sustainability. The built-in functionality and availability of oil worldwide make palm oil more attractive. It can be further modified using the cross-metathesis process for the production of bio-based polyol. In this study the cross metathesised palm oil was pre-treated with different types of pre-treatment methods namely transesterification, silylation, methylation and dilution to find the best pre-treatment method. Moreover, the pre-treated samples were analysed using two different Gas chromatography columns installed to the Gas chromatography flame ionisation detector (GC-FID). The best pre-treatment method was then used to prepare the samples taken from the palm oil octenolysis at different molar ratio of palm oil to 1-octene. According to the findings of this research, dilution method outperformed other pre-treatment methods.
