The purpose of this review article is to characterize all of the parameters regarding the types, polymers used, and release kinetics of matrix tablets. Matrix system was the earliest oral extended release platform for medicinal use. Matrix tablets are most commonly used methods to modulate the release profile of drugs. They are much desirable and preferred for such therapy because they o...

The self-preservation property of CH4 hydrates is beneficial for the transportation and storage natural gas in form hydrates. Few studies have been conducted on effects chemicals (kinetic thermodynamic promoters) properties hydrates, most available literature limited to pure water. novelty this work that we studied compared kinetics hydrate formation presence amino acids (hydrophobic hydrophili...

Short title: Transitions of a periodic hydrophilic hydrophobic chain 1 We study a single self avoiding hydrophilic hydrophobic polymer chain, through Monte Carlo lattice simulations. The affinity of monomer i for water is characterized by a (scalar) charge λ i , and the monomer-water interaction is short-ranged. Assuming incompressibility yields an effective short ranged interaction between mon...

Contact electrochemical replication (CER) is a novel pattern replication methodology advanced in this laboratory that offers the unprecedented capability of direct one-step reproduction of monolayer surface patterns consisting of hydrophilic domains surrounded by a hydrophobic monolayer background (hydrophilic @ hydrophobic monolayer patterns), regardless of how the initial "master" pattern was...
