BioMed Research International, Volume 2019, Issue 1, 2019., 2019 Over 1,000 compounds, including ecteinascidin‐743 and didemnin B, have been isolated from ascidians, with most having bioactive properties such as antimicrobial, antitumor, and enzyme‐inhibiting activities. In recent years, direct and indirect evidence has shown that some bioactive compounds isolated from ascidians are not produced by ascidians ...

Titanium Dioxide as a Catalyst Support in Heterogeneous Catalysis
The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 The lack of stability is a challenge for most heterogeneous catalysts. During operations, the agglomeration of particles may block the active sites of the catalyst, which is believed to contribute to its instability. Recently, titanium oxide (TiO2) was introduced as an alternative support material for heterogeneous catalyst due to the effect of its ...

Journal of Applied Chemistry, Volume 2013, Issue 1, 2013., 2013 A novel process was developed for oxidative desulfurization (ODS) in the absence of a phase transfer catalyst (PTC) using only Keggin heteropolyacids and their aluminum salts as catalysts. Reactions were performed in biphasic mixtures of isooctane/acetonitrile, with dibenzothiophene (DBT) as a model sulfur compound and hydrogen peroxide as the oxidant.

Biodesulfurization of the mixture of dibenzothiophene and its alkylated derivatives by Sphingomonas subarctica T7b [PDF]
, 2021 Organosulfur compounds classified as dibenzothiophenes (DBTs) and their derivatives are contained in petroleum. When used as fuel, these substances release SOx emissions, thus contributing to air pollution, acid rain, and climate change. Therefore, it is

Hydrodesulfurization of Dibenzothiophene: A Machine Learning Approach
ChemistryOpen, Volume 13, Issue 9, September 2024.This work analyzes the hydrodesulfurization (HDS) process by compiling data on catalysts derived from MoS2, including their composition, structure, and experimental conditions. Using supervised machine learning methods such as regularized regression and random forest, the study estimates the conversion of DBT and the reaction selectivity.
