We develop a self-consistent field theory for salt-doped diblock copolymers, such as polyethylene oxide (PEO)–polystyrene with added lithium salts. We account for the inhomogeneous distribution of Li ions bound to the ion-dissolving block, the preferential solvation energy of anions in the different block domains, the translational entropy of anions, the ion-pair equilibrium between polymer-bou...

Assessing the ability of soil microorganisms to dissolute poorly soluble native calcite to supply Ca2+ is a new area to be explored in reclaiming sodic soils by supplying adequate Ca2+ and reducing the recurrent sodicity. Hence, the present study aimed to isolate a calcite dissolving bacteria (CDB) from calcareous sodic soils and to understand the mechanism of calcite dissolution. Of the 33 CDB...

Bunsen reaction was performed electrochemically using cation exchange membranes prepared by a radiation-induced grafting method for application to the iodine-sulfur thermochemical water-splitting cycle. The reaction experiments using sulfuric acid dissolving sulfur dioxide as the anolyte and hydriodic acid dissolving iodine as the catholyte verified the progress of the aimed reaction. Compared ...

Allergy contact dermatitis is a common occupational disease and the protective ointments are often used by the sensitized subjects. The efficacy of the chelation ability of the barrier creams containing Na2H2EDTA was evaluated. The in vitro test with the diffusion chamber and artificial membrane was performed. The effect of the Na2H2EDTA concentration (3, 5 or 10%), pH of the buffer for Na2H2ED...

Drug delivery system is an efficient tool for enhancing market, extending product life cycles and creating opportunities. Drug delivery system (DDS) makes a significant contribution to global pharmaceutical sales through market segmentation, and is moving rapidly[1]. Despite of tremendous innovations in drug delivery, the oral route remains the preferred route for administration of therapeutic ...

among the causes that give the right to each of the couples to dissolve as a partner of marriage contract is the existence of some certain diseases in one of them. the civil law observing shiite religious jurisprudence has declared some defects of the husband or wife as the cause of dissolving. the comparative study of the mentioned articles and the views of jurisprudents and along with challen...

In recent days the use of fast mouth dissolving tablets are well accepted by elderly, children and the patients having trouble in swallowing and even by the travelling patients who find it convenient to ingest. Cinnarizine is a piperazine derivative and is widely prescribed for the treatment of vestibular disorders and motion sickness. To enhance the anti-emetic and anti-migraine properties of ...

Mouth dissolving tablets (MDTs) have received ever-increasing demand during the last decade, and the field has become a rapidly growing area in the pharmaceutical industry. Upon introduction into the mouth, these tablets dissolve or disintegrate in the mouth in the absence of additional water for easy administration of active pharmaceutical ingredients. The popularity and usefulness of the form...

BACKGROUND The Birch reduction of electron rich pyrroles does not occur readily. However, dissolving metal reduction with zinc under acidic conditions gives 3-pyrrolines (2,5-dihydropyrroles) in reasonable yield. This dissolving metal reduction was first reported by Knorr and Rabe in 1901 but since then has only been reported for the reduction of electron rich pyrroles. RESULTS The partial re...

s: Mouth dissolving tablet is the fast growing and highly accepted drug delivery system. This study was aimed at development of Ketorolac Tromethamine mouth dissolving tablet, which can disintegrate or dissolve rapidly once placed in the oral cavity. Conventional Ketorolac tromethamine tablet require water to swallow it and have disadvantages like low disintegration rate, low solubility etc.Ket...
