"Poly(lactic acid)/bacterial cellulose nanocomposites were prepared by solvent casting. Aiming to reduce the incompatibility between polar bacterial cellulose (BC) and the nonpolar poly(lactic acid) (PLA) matrix which in...

"We provide a direct quantitative comparison of molecular transport of three similarly sized but chemically different fluorescent indicators of membrane permeabilization — two cationic molecules (YO-PRO-1 and propidium...

In order to find an upper theoretical limit for the efficiency of p-n junction solar energy converters, a limiting efficiency, called the detailed balance limit of efficiency, has been calculated for an ideal case in whi...

Rifabutin loaded floating gellan gum beads were prepared by Ca++ induced ionotropic gelation in acidic medium by drop wise addition of gellan gum dispersion containing drug and gas-generating agent. The prepared beads we...

Nimesulide was formulated as novel dual coated microparticles using chitosan (CTN) and ethyl cellulose (EC) as encapsulating materials for its improved delivery to the intestine and to prevent gastric irritation and incr...

El objetivo del presente trabajo ha sido el de evaluar el efecto del peso molecular de acetobutirato de celulosa (ABC) (PM 30000 y 70000) y la presencia de polietilenglicol 1500 (PEG 1500) en el tamaño de microesferas p...

This work is focused on the development of a new particulate drug delivery system using sodium alginate (SA) and modified hydrophobic hydroxyl propyl methyl cellulose (HPMC, 60L grade) containing diclofenac as a model dr...

A biphasic gastroretentive drug delivery system of acyclovir consisted of loading dose tablet and floating multiple matrix tablets was prepared by direct compression process. The delivery system was designed by hydroxy...

In order to increase the flexibility of renewable energies and improve their integration into existing energy grids, efficient intermediate storage is necessary. High-purity hydrogen produced in a water electrolysis cell...

The present investigation aims at feasibility assessment of ethyl cellulose (EC) and polyvinylpyrrolidone (PVP) based ondansetron hydrochloride matrix type transdermal systems. The effects of polymeric concentration, its...

The aim of the study was to formulate and evaluate controlled release microspheres. Ciprofloxacin HCl, belonging to the class of fluroquinolones, was chosen as the model drug. The drugloaded microspheres were prepared wi...

A new Lagrangian formulation is introduced. It can be used to make molecular dynamics (MD) calculations on systems under the most general, externally applied, conditions of stress. In this formulation the MD cell shape a...
