In this study, chitosan and alginate were selected to prepare alginate/chitosan nanoparticles load the drug lovastatin by ionic gelation method. The synthesized loaded with characterized Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), laser scattering differential calorimetry (DSC) methods. FTIR spectrum of alginate/chitosan/lovastatin showed that interacted through hydrogen bonding dipolar-dipolar interactions between C-O, C=O, OH groups in lovastatin,...
Collagen from fish scale waste is currently being studied as a promising biological material to replace collagen animals because of advantages such safe, fat-free, not suffering communicable diseases, and easy absorption in human body solutions. Finding the suitable process extracting necessary scales by chemical methods often requires long time. Therefore, this paper, some bases acids at different concentrations were chosen find most condition for wastage fishes belonging familiar Cyprinus...
Three different kinds of plastic bags HL, VHL, and VN1 with chemical nature were degraded by a novel thermophilic bacterial strain isolated from composting agricultural residual in Vietnam shaking liquid medium at 55 °C after 30 d. The new was classified the Bacillus genus morphological property sequence partial 16Sr RNA coding gene named as sp. BCBT21. This could produce extracellular hydrolase enzymes including lipase, CMCase, xylanase, chitinase, protease level activity same media. After...
This paper presents some characteristics, properties, and morphology of TiO2 nanoparticles (nano-TiO2) modified with various contents 3-(trimethoxysilyl)propyl methacrylate (TMSPM) coupling agent. The treatment process was carried out in ethanol solvent at 50oC using ammonia as a catalyst for hydrolysis reaction silane to silanol. Infrared spectroscopy, thermogravimetric analysis, transmission electron microscopy, field emission scanning dynamic light scattering, ultraviolet-visible X-ray...
The purpose of this study is to fabricate composites based on poly(lactic acid) (PLA), thermoplastic starch (TPS) and TiO2 nanoparticles (n-TiO2), investigate the effects interface compatibility TPS PLA. FTIR spectra confirmed that interfacial interaction between components formation hydrogen bonding PLA/TPS matrix (Ti-O-C bond). results indicated tensile properties blends were strongly influenced by ratio which decreased with increasing content. Besides, strength was improved in presence...
Hydrotalcite-Ag nanoparticles (HT-Ag NPs) have garnered significant attention in research due to their remarkable antibacterial activity and excellent photocatalytic properties. Consequently, they been utilized various fields, such as pharmaceuticals, medicine, electronics, environmental treatment. However, the synthesis of HT-Ag often involves use NaBH4, a chemical reducing agent, reduce Ag (I) ions form NPs on HT. Nevertheless, residue agents can lead pollution above mentioned. The...
Metal corrosion is a challenge for the world with heavy impacts on economy. Study development of effectiveness anticorrosion additives promising strategery protection industry. This research focuses modification hydrotalcite Mg-Al (HT) loading tannic acid (TA) 3-(trimethoxy silyl) propyl methacrylate organo-silane (TMSPM) applicating as an anti-corrosion additive epoxy coating steel substrate. The suitable ratio HT and modifiers was investigated content modified in matrix found based...
Polypyrrole (PPy) films doped with molybdate and salicylate have been successfully electropolymerized on low carbon steel in aqueous solutions containing both a one-step process that did not require any pre-treatment of the substrate. Salicylate-doped PPy were synthesized same way for comparison. The surface was rapidly inhibited PPy-based formed it easily. characterized by Fourier transform infrared, scanning electron microscopy, energy dispersive X-ray, thermal gravimetric analysis...
Abstract This article focuses on comparing the characteristics of cotton fabric dyed with Diospyros mollis extract (DME) solution and that reactive dye. The parameters after dyeing both types dyes were assessed, including color strength (K/S), structural morphology, infrared spectrum, antibacterial properties, UV resistance, fastness to washing, rubbing, light, moisture absorption, breathability, wastewater indices. obtained results show K/S value DME is slightly lower than dye, 18.52 19.36,...
