The high methanol crossover and high cost of Nafion® membrane are the major challenges for direct methanol fuel cell application. With the aim of solving these problems, a non-Nafion polymer electrolyte membrane with low methanol permeability and high proton conductivity based on the sodium alginate (SA) polymer as the matrix and sulfonated graphene oxide (SGO) as an inorganic filler (0.02-0.2 ...

p-Cresol is an environmental pollutant due to its vast use, toxicity and persistence, nevertheless, its degradation in an enzyme is unclear. In this study, we used Pleurotus sp. isolate VLECK02 polyphenol oxidase (PPO) for the determination of p-cresol degradation. On the basis of UV, FT-IR and chromatographic (HPLC and GC-MS) analysis, 4-methylcatechol was identified as the main metabolite of ...

Multiple shoots were achieved through axillary bud explant of Spilanthes acmella on MS medium supplemented with 0.5mg/l BA. In vitro developed axillary buds and tiny shoots isolated from the multiple shoots were encapsulated in different strength of sodium alginate. The present work explains the role of components of culture medium on morphogenic response of encapsulated shoot tips to various t...

The aim of this research was to investigate the influence of hydrocolloid pre-treatment, i.e. pectin, carboxymethyl cellulose (CMC), gum arabic and sodium alginate on the quality of vacuum fried jackfruit (JF) chips. The control JF samples (no hydrocolloid treatment) showed higher absorption of oil whereas the oil absorption was less in the hydrocolloid pre-treated samples. The retention of moi...

The objectives of this study were to use soybean cake as the raw material for the production of isoflavone powder and compare the effects of different carriers as well as drying methods on the powder quality. Results showed that with spray drying, a level of 40% maltodextrin as carrier produced the highest yield (mass) of isoflavone powder, followed by 10% gelatin and 1% sodium alginate. Howeve...

3D printing technology has great potential for the reconstruction of human skin. However, reconstructed skin some differences from natural skin, largely because hydrogel used does not have appropriate biological and physical properties to allow healing regeneration. This study examines swelling, degradability, microstructure Collagen/Sodium Alginate (Col/SA) hydrogels differing compositions pur...

A study was conducted to develop banana flour based edible film using Response Surface Methodology. A Central Composite Design was adopted in the optimization of banana flour and sodium alginate level for the development of edible film with 13 different runs and 5 trials of two similar centre points. Effects of banana flour (2-4% w/v) and sodium alginate (0.5-1.0% w/v) level on the thickness, m...

PURPOSE To examine the CT and MR appearances of four packing materials commonly used in otolaryngologic surgery. METHODS The CT and MR appearances of bismuth and iodoform paraffin paste, aqueous betadine gauze, calcium sodium alginate, and triadocortyl cream were examined. CT attenuation values were measured using phantoms containing packing materials. MR characteristics were examined by pack...

The purpose of this work was to develop a multiparticulate system exploiting the pH-sensitive property and biodegradability of calcium alginate beads for intestinal delivery of ceftriaxone sodium (CS). CS was entrapped in beads made of sodium alginate and sodium carboxymethylcellulose (CMC), acacia, HPMC K4M and HPMC K15M as drug release modifiers. Beads were prepared using calcium chloride as ...
