Fucoidans from brown macroalgae (brown seaweeds) have different structures and many interesting bioactivities. are classically extracted seaweeds by hot acidic extraction. Here, we report a new targeted enzyme-assisted methodology for fucoidan extraction seaweeds. This protocol involves one-step combined use of commercial cellulase preparation (Cellic®CTec2) an alginate lyase Sphingomonas sp. (SALy), reaction at pH 6.0, 40 °C, removal non-fucoidan polysaccharides Ca2+ precipitation,...
ZnO nanomaterials are some of the most excellent candidates for low-cost but high-performance photodetectors, particularly in UV region. Besides doping, architecting to extend their application is still attractive developing optoelectronic devices. Thereby, this study introduces innovation nanorod-based photodetectors by combining two techniques, which Cu doping and core/shell structuring. Particularly, active material (ZnO/(Cu-doped ZnO) nanorods) was synthesized a easy fabrication process....
Rice husk is one of the most abundant biomass resources in world, yet it not effectively used. This study focuses on sustainably rice-husk-extracted lignin, nano-lignin (n-Lignin), lignin-capped silver nanoparticles (LCSN), n-Lignin-capped (n-LCSN), and silica-silver (LCSSN), using them for antibacterial activities. The final n-Lignin-based products had a sphere-like structure, which size varied between 50 80 nm. We found that while n-Lignin lignin were less effective against Escherichia...
These days, photodetectors are a crucial part of optoelectronic devices, ranging from environmental monitoring to international communication systems. Therefore, fabricating these devices at low cost but obtaining high sensitivity in wide range wavelengths is great interest. This report introduces simple solution-processed hybrid 2D structure CuO and rGO for broadband photodetector applications. Particularly, acts as the active material, absorbing light generate electron-hole pairs, while...
The fabrication of a hybrid UCMPs/RGO based photodetector with enhanced device performance under infrared light illumination.
For the vulcanized natural rubber (NR), incorporation of silver nanoparticles (AgNPs) into NR matrix did not exhibit bactericidal property against Escherichia coli ( E. ). However, AgNPs polyethylene (PE) showed good antibacterial activities to both Gram-negative and Gram-positive bacteria. In present work, NR/PE (85/15) blends have been prepared by melt blending with presence compatibilizer in an internal mixer. To possess property, (5–10 nm) or Fe 3 O 4 –Ag hybrid (FAgNPs, 8 nm/16 were...
Nanohybrids of zinc oxide/cellulose nanocrystals (ZnO/CNCs) were successfully prepared by using a low cost and green method for adsorption photocatalytic degradation methylene blue (MB). CNCs have been derived through the hydrolysis reaction citric/hydrochloric acid from pure cellulose isolated Vietnamese Nypa fruticans trunk. The influence Zn 2+ ion concentration on morphology, microstructure, thermal properties as well activity ZnO/CNC nanohybrids was investigated in detail. Analyses FTIR...
Endo-fucoidanases, including EC 3.2.1.211 endo-α-1,3-L-fucanase and 3.2.1.212 endo-α-1,4-L-fucanase activities, catalyze depolymerization of fucoidans - a group bioactive, sulfated fucosyl-polysaccharides found primarily in brown macroalgae (brown seaweeds). Quantitative assessment endo-fucoidanase activity is critical for characterizing kinetics comparing the action different endo-fucoidanases on types fucoidans. However, current state-of-the-art assay consists qualitative based...
