Previous studies provide substantial evidence that catechins, polyphenol bioactive compounds, exhibit medicinal benefits. These polyphenols are found in abundance in green teas, including a combination of the four major types of catechins: (-)-Epicatechin (EC), (-)-Epicatechin-3-gallate (ECG), (-)- Epigallocatechin (EGC), and (-)- Epigallocatechin-3-gallate (EGCG). Although all four exhibit medicinal benefits, the catechin cited in t Read More

Aims: Oxidation of p-anisaldehyde by Quinolinium dichromate (QDC) in the aqueous acetic acid medium in the presence of sulphuric acid using surfactants. Background: The oxidation studies of anisaldehyde is very important as the oxidized products are used as a synthetic intermediate for the preparation of a variety of drugs. Quinolinium dichromate (QDC) has emerged as a very useful and versatile oxidant. Micellar mediu Read More

Introduction: Two key features of an emulsion, stability and viscosity, are not only considered dependent on ingredient quantities but also delicately affected by emulsification conditions, such as pH, temperature, and mixing conditions. Methods: In the laboratory, we formulated an O/W emulsion made up of 41% water, 9.8% silicon (polydimethylsiloxane), 22.1% liquid sucrose (700 mg/ml), 22.1% light liquid paraffin, and 1.5 to 5% Read More

Background: Historically, the coincidence of classical thermodynamic entropy and statistical entropy is based on an assumption (the so-called Boltzmann-Planck relation). The study shows that the Boltzmann-Planck relation is not valid in general. Aims: The study demonstrates that thermodynamic entropy is a physical entity distinct from statistical entropy. Methods: Initially, the entropy of ideal gases is examined an Read More

Background: Organic synthesis, under environment-friendly circumstances, has a great impact on sustainable development. In this perspective, visible light photocatalysis has emerged as a green model, as this offers an energy-efficient pathway towards organic conversion. Light has been used as an energy source in this study, which is also a green approach to a sustainable environment. Methods: An investigation of the ef Read More
