Bitter vetch protein films containing positively charged spermidine, alone or with low amounts of glycerol, showed high tensile strength that progressively decreased by increasing the plasticizer concentration. Accordingly, lower film elongation at break and higher Young's module values were detected in the presence of the polyamine without or with small amounts of glycerol. These data suggest ...

The aim of our research was to investigate theeffect of the length of the polymer chain and the concen-tration of triethyl citrate used as a plasticizer on the thermalstability of the film structure in the case of two ethyl cel-lulose films (EC 10 and EC 45) used for preparing MRdosage forms. The influence of storage time was studied bymonitoring the changes in the therm...

Jude K. Coompson, B.S. Marquette University, 2014 Benzene is a constituent component of crude oil that has been classified as a carcinogen by the EPA with a maximum contamination level (MCL) of 5ppb in drinking water. However, of the aromatic compounds, benzene has one of the lowest polymer-water partition coefficients using commercially available polymers as sensor coatings, resulting in poor ...

Objective(s): A Box-Behnken design was used for evaluation of Eudragit coated diclofenac pellets. The purpose of this work was to optimize diclofenac pellets to improve the physicochemical properties using experimental design. Materials and Methods: Diclofenac was loaded onto the non-pareil beads using conventional coating pan. Film coating of pellets was done at the same pan. The effect of pla...

The use of Acetyl Salicylic Acid (ASA) in the secondary prevention of cardio vascular diseases is well known. Orally administered ASA is rapidly metabolized to its principal metabolite Salicylic Acid (SA) in the gastrointestinal fluids, during absorption in the intestine and liver. ASA, and not its hydrolysis product SA, which exhibits antithrombotic activity. Transdermal delivery of acetylsali...

The article presents a comparative analysis of the methods introducing fine perlite into cement systems. first method is dry mixing additive with cement, followed by water polycarboxylate plasticizer. second based on powder stabilized suspension finely dispersed instead water. Before introduction studies its aggregation and sedimentation stability were carried out. It was found that suspensions...

Sphingobium sp. strain TCM1 and Sphingomonas sp. strain TDK1 are haloalkyl phosphate flame retardant- and plasticizer-degrading bacteria. We report here the draft genome sequences of these strains to provide insights into the molecular mechanism underlying their degradation ability.

The plasticizer di(2-ethylhexyl) phthalate (DEHP) is widely used in building materials. DEHP is identified as the major plasticizer exposure in dwellings. We provide evidence that inhalation exposure to DEHP as aerosols adsorbed to particulate matter is as important, or more important, than vapor phase exposure. The particulate inhalation exposure to DEHP is considered to be significant due to ...

The development of polymers that can spontaneously repair themselves after mechanical damage would significantly improve the safety, lifetime, energy efficiency and environmental impact of man-made materials. Most approaches to self-healing materials require the input of external energy, healing agents, solvent or plasticizer. Despite intense research in this area, the synthesis of a stiff mate...

Plasticizers are usually added to polymers to give them the desired flexibility and processability by changing the dynamical properties of the polymer chains. It is therefore important to give a quantitative description about how the dynamic behavior of a given polymer is modified by the incorporation of a second component. We analyze in this work, by means of dielectric spectroscopy, the dynam...
