2023-10-29T11:23:41+0530

Objective: The current work focuses on the role of surfactant in photogalvanic cells and how photons from sunshine can be exploited as a driving factor for energy conversion and storage.

Methods: An H-shaped pg unit was created to investigate electrical output in solar changes. Dye, reductant, surfactant, NaOH, double distilled water (DDW), multi-meter, calomel electrode, 250 k roistered, saturated calomel electrode, platinum electrode, carbon pot, resistance key, digital pH meter, microammeter, and 200 W tungsten bulb were used in the suggested electrical circuit. The proposed solar cell's reaction mechanism for generating photocurrent and photocurrent has been thoroughly investigated. For the sunlight-powered transition system, PG Cells were investigated.

Findings: Photocurrent, photo potential, efficiency of conversion, fill factor, and cell performance were all examined in PG cells. The values mentioned above are as follows: 388.0 A, 1141.0 mV, 0.7995%, 0.5389, and 129.0 minutes were measured. The cell's electrical output has also been seen for tetrazine, D-Fructose, and lauryl glucoside systems. Potential at power point, open circuit potential, power point of cell (pp), and current at short circuit were also investigated. The values obtained are as follows: 1133 mV, 1523 mV, 435.321, and 544A are the values.

Novelty: There seems to have a lot of study done on photogalvanics, but no one has concentrated on green dye-based work for a more sustainable future. As a result, an actual research work plan for comprehensive investigation in the field of photogalvanic devices for solar energy transformation was developed. The photo galvanic is an expanding area of research, and the manuscript contains significant electrical output, conversion efficiency, and storage capacity of developed photogalvanic cells, with particular focus on to better performance (t_1/2) and decreasing the expense of the photogalvanic cell to enhance business viability

Synthesis and in vitro antimicrobial, antiprotozoal and antitumor evaluation of phenothiazine linked 1,2,4-triazoles

2023-10-23T09:37:19+0530

Aim: The purpose of this study is to create compounds containing phenothiazine triazoles and test them against various bacterial, fungal, protozoan, and M. tuberculosis H37Rv species. Anti-tumor efficacy is also included.

Background: Phenothiazine comprises two separate hetero atoms, Sulphur and nitrogen, and the 1,2,4-triazoles nucleus has been identified as an antifungal agent with three nitrogen-containing heterocyclic rings. In medicinal chemistry, the nucleus is significant on both counts. Both of these heterocycles are associated in this study with enhancing the therapeutic value.

Objective: Phenothiazine is widely known for its antibacterial, antihistamine, sedative, spasmolytic, and anticancer activities. 1,2,4-triazoles nucleus is the active component of antifungal medications. When these two heterocycles are joined, the biological profile may be improved. The primary goal of this study is to assess the various biological activities of freshly synthesized 1,2,4-triazoles including phenothiazine.

Method: Condensation of 2-chloro-5-(4-hydroxyphenyl)-1-(phenothiazin-10-yl)-ethanone-1 is the method. -2-amino-1,3,4-oxadiazole-2 is then used to create a range of phenothiazine-linked triazoles (5a–m) by reacting with different acid hydrazides. All recently synthesized substances have their structural integrity confirmed using data from IR, ¹H-NMR, ¹³C-NMR, and mass spectrometry. All synthesized substances were evaluated for their antimicrobial, antiprotozoal, and anticancer activities. By connecting the nitrogen of phenothiazine to monocyclic heterocycles like oxadiazole and triazole via the alkyl chain showed significant biological activity of the newly synthesized compounds 5a–m.

Result: Biochemical testing revealed that compounds 1, 2, 3, 5a, 5d, 5e, 5f, 5k, and 5l had antibacterial activity. The antifungal activity of vitamins 5b, 5c, 5d, 5f, and 5k is active. Active against M. tuberculosis are 5d and 5k. In comparison to normal medications, 5a, 5i, 5j, 5k, and 5l showed higher percentages of lysis on T. Cruzi. The anti-tumor effects of 5a, 5j, and 5l were present.

Conclusion: Antibacterial, antifungal, antiprotozoal, and antitumor activities have all been assessed in this study. The majority of recently created compounds have been shown to be biologically active agents. The primary emphasis of this research is the novel compounds' anti-protozoal action

2023-10-23T11:03:04+0530

India is the world’s third-largest energy consuming country. Due to expanding economy, population, urbanization and industrialization energy demand is increasing continuously. Conventional energy sources such as coal, natural gas, oil or nuclear are exhaustible and have harmful environmental impacts such as air pollution, climate change, and natural resources decay. Therefore, there is a need of alternative sources of energy such as wind energy, solar energy. hydro energy. biomass energy and geothermal energy etc. These energies are renewable and ecofriendly. Solar energy is one of the renewable energy resources with significant potential to resolve the existing energy challenges. For the generation of this energy solar photovoltaic cells are being used which are reliable, clean, scalable, provide affordable energy, and are cost-effective in the long term.
