We report definitive evidence for an effective interfacial tension between two types of miscible fluids using spinning-drop tensiometry (SDT). Isobutyric acid (IBA) and water have upper critical solution temperature (UCST) 26.3 degrees C. created a drop the IBA-rich phase in water-rich below UCST then increased above it. Long after reached thermal equilibrium, persists. By plotting inverse radius cubed (r(-)(3)) vs rotation rate squared (omega(2)), we confirmed that exists estimated its...
Poly(dimethyltin glutarate) is presented as the first organometallic polymer, a high dielectric constant, and low loss material. Theoretical results correspond well in terms of constant. More importantly, constant can be tuned depending on solvent film polymer cast from. The breakdown strength increased through blending with second polymer.
Astaxanthin (ASX) is a xanthophyll pigment considered as nutraceutical with high antioxidant activity. Several clinical trials have shown the multiple health benefits of this molecule; therefore, it has various pharmaceutical industry applications. Commercial astaxanthin can be produced by chemical synthesis or through biosynthesis within different microorganisms. The molecule microorganisms highly preferred due to its zero toxicity and superior therapeutic properties. However,...
Capsaicinoids obtained from lyophilized serrano chili by sorbitan monooleate solutions were investigated. Sorbitan was as effective methanol in extracting capsaicin and dihydrocapsaicin (DHC). Subsequently, a Box–Behnken design used to optimize capsaicin, DHC, polyphenol extraction, well evaluate the antioxidant capacity of dehydrated chili. Particle size (PS) (20–60 mesh), processing temperature (55–75 °C), concentration (1.5–2.5%) selected independent variables. The statistical analysis...
The application of green methods in the synthesis nanoparticles using plants is a cost-effective and eco-friendly approach. Zinc oxide are great importance due to their versatile properties. conditions strongly influence characteristics functionality nanoparticles. present work studied biological, zinc (ZnONPs) presence different concentrations ethanolic extract Larrea tridentata (10, 20, 30 mg/mL). time formation was evaluated at temperatures pH values reaction medium. ZnONPs confirmed by...
New and improved approaches are urgently needed to fight the increasing number of multi-drug resistant bacteria. The antibacterial effect silver nanoparticles (AgNPs) prepared by standardized chemical biological syntheses is compered here. Biological systems included extracts Opuntia ficus-indica mucilage extracellular growth broth Aspergillus niger Bacillus megaterium. were characterized infrared spectroscopy, IR, transmission electron microscopy. All AgNPs shared characteristic IR peaks...
Small-angle and ultrasmall-angle neutron scattering (SANS/USANS) measurements were used to determine the structural changes induced by photopolymerization of AOT/D2O/(dodecyl acrylate) inverse microemulsion systems. Scattering profiles collected for initial microemulsions films resulting from oil phase. The SANS data modeled as spherical, core−shell droplets. Upon polymerization, clear mircoemulsions formed opaque films. From SANS/USANS films, it was apparent that this morphology not...
Zinc oxide nanoparticles have gained attention in the last decades due to their versatile applications; agriculture, they been used for multiple benefits. In this study, effects of zinc nanoparticles, obtained via chemical and biological synthesis 70–80 nm size, on germination seedling growth Capsicum annuum Solanum lycopersicum seed were determined. The physiological parameters, photosynthetic pigments, content total phenols, flavonoids, as well antioxidant capacity...
Abstract All‐trans retinoic acid (ATRA) has been extensively studied as an integrating component of endocrine functions in the pancreas. The aim this study was to evaluate effects ATRA on physiopathological biomarkers experimental model rat with type 1 diabetes induced by alloxan (T1D). Twenty Wistar rats were divided equally into five groups, each receiving a different treatment: control group (CG), diabetic without T1D treatment, treated ATRA, supplemented vitamin E (VIT E), and that given...
Abstract Previously, we used 2D films to identify an annealed PCL‐PDLLA phase‐separated blend morphology which provided nanoscale surface texture and patterning that stimulated osteoblast differentiation. In order translate these nanopatterning effects the walls of 3D salt‐leached scaffolds, phase scaffold must be characterized. For NaCl is as a porogen, may affect separation in blends. However, it not possible characterize using standard approaches such AFM or optical microscopy, since...
The objective of this study was to evaluate the effect an edible coating based on alginate and acemannan commercial quality concentration bioactive compounds guava pieces stored in refrigeration. Pieces were coated with film enriched (A-Ac), samples without cover used as a control. fruit A-Ac for 12 days at 6 ± 2 °C. Analyses colour, firmness, ethylene production, ascorbic acid, total polyphenols, antioxidant potential, polyphenol profile performed 0, 3, 6, 9, storage. In addition, sensory...
Abstract Hydrophobic polymer films, having an aqueous phase distributed throughout the matrix, were formed by polymerizing a solution of dodecyl acrylate and 1,6 hexanediol diacrylate containing nanometer‐sized drops water stabilized sodium bis(2‐ethylhexyl) sulfosuccinate (AOT). Photopolymerization‐induced aggregation and/or separation occurred, as initially clear solutions became opaque films. The polymerized films clear, relative humidity was reduced. Clear still contained 20–50% initial...
Lactose-free dairy products are a valued consumer option for lactose intolerant individuals. Short-term ultra-high pasteurization (UHT) allows the preparation of sterile milk products. Manufactures define useful shelf life UHT as 120 days. This study analyses lactose-free with low-fat content over days storage. Milk composition, microbial presence, structure (micellar size and zeta potential), color, pH, protein hydrolysis were examined. At storage pH decrease, change in particle...
