(2013-11-01)
Trials were carried out in Juazeiro, Bahia State, Brazil, aiming to test plant regulators composed by gibberellin, cytokine and auxin effects on chemical quality of Superior Seedless grape berries. The first trial studied ...
Valorisation of soy by-products as substrate for food ingredients containing L. casei through solid state fermentation
(Elsevier Science, 2020-10)
Okara and soybean extruded-expelled meals (EEM) were used for preparation of ingredients containing probiotics applying a sustainable technology as solid state fermentation. The effect of three factors: particle size of ...
Catalytic behavior of the WOx-ZrO2 system in the clean selective oxidation of diphenyl sulfide (DPS)
(Elsevier Science, 2021-07-12)
WOx-ZrO2 (ZWx) based catalysts were prepared by equilibrium adsorption in basic condition (pH 10) with W content of 10.5, 19.7 and 27.0 wt.%, using hydrous zirconia [ZrO2(383)] as support. In order to determine the soluble ...
Influence of carrot fibre powder addition on rheological, microstructure and sensory characteristics of stirred‐type yogurt
(Wiley Blackwell Publishing, Inc, 2019-10)
The incorporation of 1% (E1) and 2% (E2) of the carrot fibre powder obtained from carrot discards to yogurts was studied. The effect of the fibre addition on the physicochemical parameters, waterholding capacity (WHC), ...
XPS studies on the Cu(I,II)-polyampholyte heterogeneous catalyst: An insight into its structure and mechanism
(Elsevier Science, 2011-04-01)
A complex between Cu(II) and a polyampholyte synthesized from methacrylic acid, imidazole and ethyleneglycol diglycidyl ether was used as a heterogeneous catalyst for hydrogen peroxide activation and degradation of ...
Hexavalent chromium removal in contaminated water using reticulated chitosan micro/nanoparticles from seafood processing wastes
(Elsevier, 2015-07)
Chitosan particles (CH) were obtained from seafood processing wastes (shrimp shells) and physicochemically characterized; deacetylation degree of CH was measured by Infrared Spectroscopy (FTIR) and potentiometric titration; ...
Polyphosphate Poly(amine) Nanoparticles: Self-Assembly, Thermodynamics, and Stability Studies
(American Chemical Society, 2019-11)
The interaction of polyamine poly(allylamine hydrochloride) with Na3PO4, Na4P2O7, Na5P3O10, Na6P6O18, and (NaPO3)26 salts and the formation of polyamine phosphate nanoparticles (PANs) are studied here. Dynamic light ...
Using Polymer Hydrogels for Glyphosate Sequestration from Aqueous Solutions: Molecular Theory Study of Adsorption to Polyallylamine Films
(American Chemical Society, 2018-10)
A molecular theory has been applied to study the equilibrium conditions of glyphosate and aminomethylphosphonic acid (AMPA) adsorption from aqueous solutions to hydrogel films of cross-linked polyallylamine (PAH). This ...
Hydrogelsand metallo-hydrogels: characterization,and their environmental and pharmaceutical applications
(Nova Science Publishers, 2017)
The versatility on the applications of hydrogel materials make them veryattractive as adsorbents than can be used for decontamination of pollutants as well for drug-delivery. Adsorption is an efficient option for decontamination ...
Customized design of electronic noses placed on top of air-lift bioreactors for in situ monitoring the off-gas patterns
(Springer, 2012-06)
A specially designed electronic nose was coupled to an air-lift bioreactor in order to perform on-line monitoring of released vapors. The sensor array was placed at the top of the bioreactor sensing the headspace in ...
