Minimally processed pomegranate rapidly loses its overall quality because of high water loss and microbial contamination. Nano-ZnO in combination with carboxymethyl cellulose (CMC) coating was used on pomegranate arils. Arils were dipped for 4min in distilled water (control), 0.1 or 0.2% (w/v) nano-ZnO suspension and then ZnO treated arils were coated with 0.5% (w/v) CMC and stored for 12days a...

nano-zeolite coapo-5 as a member of afi family, was synthesized via a hydrothermal treatment, and structurally characterized using x-ray diffraction (xrd), scanning electron microscope (sem), and energy dispersive x-ray analysis (edax). the effects of crystallization temperature and time on the structure of these powder products were studied. xrd patterns of the synthesized powders revealed a h...

This critical review provides a processing-structure-property perspective on recent advances in cellulose nanoparticles and composites produced from them. It summarizes cellulose nanoparticles in terms of particle morphology, crystal structure, and properties. Also described are the self-assembly and rheological properties of cellulose nanoparticle suspensions. The methodology of composite proc...

The effect of NaOH concentration values was observed on the cellulose structure Cladophora. Cladophora is synthesized from sp., a green alga that lives in aquatic environments (seawater and freshwater) soil surfaces (rocks wetlands). Cellulose synthesis carried out through processes bleaching, alkali hydrolysis, acid hydrolysis. Bleaching uses NaClO 2 , alkaline hydrolysis with varying concentr...

An amorphous complex precursor with uniform Mn/Ni cation distribution is attempted for preparing a nano-structured layered Li-rich oxide (Li1.2Mn0.6Ni0.2O₂)cathode material, using diethylenetriaminepentaacetic acid (DTPA) as a chelating agent. The materials are characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electr...

Dissolution of cellulose is an important but difficult step in biofuel production from lignocellulosic materials. Steam and supercritical carbon dioxide (SC-CO2) explosion are two effective methods for dissolution of some lignocellulosic materials. Loading and explosion are the major processes of these methods. Studies of these processes were performed using grand canonical Monte Carlo and mole...

The effect of bacterial cellulose (BC) on the freeze-thaw stability of rice starch gels during 5 freeze-thaw cycles were investigated, using scanning electron microscopy (SEM), rapid visco analyzer (RVA), X-ray diffractometry (XRD), differential scanning calorimetry (DSC) and textural analyzer (TA). SEM micrographs of freeze-thaw gels showed that smaller pore size and a thicker surrounding matr...

The nano-Fe3O4 particles were prepared by hydrothermal method. Cellulose-based magnetic Fe3O4 was prepared by adding cellulose solution dissolved in sodium hydroxide / thiourea / urea system. The basic protease was used as the catalyst and glutaraldehyde was used as the crosslinking agent, The production of magnetic recyclable immobilized enzyme can greatly reduce the cost of hydrolysis of slud...

The development of nano-scaled photonic crystal structures has resulted in many new devices exhibiting non-classical optical behavior. Typically, in these structures a photonic band gap and associated defect mode are used to create waveguides, resonators, couplers and filters. In this paper we propose that the functionality of these structures can be significantly enhanced by the infiltration o...
