Supercritical carbon dioxide extraction (scCO2) is chosen to a treatment to remove lignin and to peel off outer cell wall layers to expose S2 layer of aspen wood fibres. The aim is to find an effective and environmentally friendly method to advance the fibrillation of the BCTMP pulp. The effects of the treatment are analysed by using scanning electron microscopy (SEM). The chemicals used togeth...

Bicontinuous interfacially jammed emulsion gels (bijels) comprise networks of interpenetrating domains two immiscible liquids stabilized by nanoparticles at the fluid–fluid interface. Bijels were first reported in simulation, which subsequently spurred experimentalists to develop fabrication approaches including thermal quenching, cosolvent removal, and direct mixing explore bijels applications...

Equilibrium constants of Cadmium Oxide (CdO) nanoparticles complexes in human cancer cells with DNA/RNA ligands have been studied with biospectroscopic methods such as 1HNMR, 13CNMR, 31PNMR, Attenuated Total Reflectance Fourier Transform Infrared (ATR–FTIR) and FT–Raman spectroscopies in cosolvent systems at 10, 20, 30°C ± 0.5 and 1 mol.dm–3 ionic strength, was maintained using Sodium Chloride ...

Introduction Dense non-aqueous phase liquids (or DNAPLs) are liquids that are water immiscible and at the same time are heavier than water. When a spill occurs, these liquids can migrate into aquifers and become trapped in the pores. Some techniques proved to be efficient for the recovery of DNAPLs from the aquifers. One method is the injection of fluids through injection wells, for example, co...

Electrospinning is a versatile process used to prepare micro- and nano- sized fibers from various polymers dissolved in volatile solvents. In this report, cellulose and cellulose-heparin composite fibers are prepared from nonvolatile room temperature ionic liquid (RTIL) solvents by electrospinning. RTILs are extracted from the biopolymer fiber after the fiber formation using a cosolvent. Micron...

We carried out the mechanochemical polymerization of methacryloyl derivatives of acetoaminophen and 5-fluorouracil in the presence of lactose. The reaction proceeded readily and the polymeric prodrugs were quantitatively produced. This method produces powdered polymeric prodrugs in which fine particles of lactose are homogeneously dispersed, since the reaction proceeds quantitatively through a ...

in this research, mesoporous silica was applied as the host of corrosion inhibitor (molybdate). the loaded mesoporous silica was dispersed in an epoxy matrix. the composite was then coated on the mild steel plate. results showed that the corrosion resistance of the scratched epoxy/mesoporous silica loaded by molybdate was better than the one without molybdate or neat epoxy. on the other hand, e...

Preparation and uses of quinaldinium dichromate and its polymeric analogue poly (2- vinylquinolinium) dichromate as the new monomeric and polymeric oxochromium-amine complex reagents for oxidizing variousorganic compounds, with emphasis on the latter, are described

nowadays, developements in nanotechnology have leeds an increased application of this newborn technology in cancer treatment. in this study, a stabilized micelle was developed to load hpd in order to be used in photodynamic treatment of cancer in an animal model. to construct micelles, pluronic p-105 was used and stabilized to encapsulate hpd . this process includes a 24 h polymerization in whi...
