Pickering emulsions stabilized by ethyl cellulose nanoparticles have recently received –great attention for their remarkable stability and numerous industrial applications. De- spite this, the exact stabilization mechanism of such is still not fully understood. Both emulsion particle adsorption at inter- face through network formation in continuous phase (leading to a yield stress) been suggest...

Various cellulose-ionic liquid solutions were measured with a rotational plate-andplate rheometer and a Capillary Break-up Extensional Rheometer (CaBER). Comparison of the shear and extensional rheological properties showed good agreement in some cases. The CaBER, however, seems to be more sensitive to small variations in solute composition. INTRODUCTION Since almost a decade now, nonderivatizi...

Enabling technologies for efficient use of the bio-based feedstock are crucial to the replacement of oil-based products. We investigated the feasibility of luminescent conjugated oligothiophenes (LCOs) for non-destructive, rapid detection and quality assessment of lignocellulosic components in complex biomass matrices. A cationic pentameric oligothiophene denoted p-HTEA (pentamer hydrogen thiop...

This study aimed to improve the surface properties of lignocellulosic cellulose fiber using oxidative grafting method. Various acrylic monomers were used, including methyl methacrylate, acrylate, ethyl and varying monomer concentrations. In addition, effect ceric ammonium nitrate (CAN) as an initiator on efficiency modification was investigated. The experimental results showed that kind concent...

The investigation is to study the effect of polymers on compressibility and release of Metoprolol Tartarate from tablet through direct compression. Tablets were prepared by direct compression by mixing with commonly used polymers, Eudragit RL-100, Chitosan, Ethyl cellulose, Hydroxyethyl cellulose and hydroxypropylmethyl cellulose K-100 in 1:1 ratio. The compressibility parameters were estimated...
