Chitosan-silica- polyethylene Glycol (Ch/Si/P) Solid Membrane for Removal of Cu(II), Zn(II) and Cd(II) Ions from Aqueous Solutions

Chitosan is thought to be an interesting raw material for membrane production because it has functional groups of –NH2 and –OH that are easily modified. The chitosan membrane has flaws such as low…

Exploration of Newer Possibilities to the Synthesis of Diazepine and Quinoline Carboxylic Acid Substituted Analogues of Benzothiazolo Condensed Oxocarbazoles and Oxoazacarbazoles of Medicinal Interest

Chemists have been drawn to heterocyclic systems containing benzothiazoles, carbazole (and azacarbazole) moieties because these nuclei have been identified in the literature as the most promising pharmacophores in drug design and synthesis. Based…

Time Dependent Aspects of Adsorption: Evaluating the Lifetimes within the Hysteresis Loop

When fluids adsorb in mesoporous material in contact with a vapour reservoir, the phenomenon of hysteresis occurs frequently. It piques my interest because it appears to contradict thermodynamics, which states that a system’s…

A New Theory and Its Applications: Fluids in Mesopores

Despite the fact that hysteresis in fluid adsorption in porous material has been known for over a century, the thermodynamic treatment of this phenomenon is still unknown. We propose that we recognize that…
