Silicates characterization as potential bacteriocin-carriers
(Elsevier, 2010-01)
Two different silicates, zeosil and expanded perlite, were characterized as potential carriers of a bacteriocin with anti-Listeria monocytogenes activity, produced by Enterococcus faecium CRL1385. Specific surface areas ...
N-(Phosphonomethyl)Glycine Interactions With Soils
(Asociación Química Argentina, 2005-08)
Glyphosate is a non selective, broad spectrum, postemergent herbicide widely used in weed control. The adsorption isotherms and surface coverage of glyphosate (NPhosphonomethylglycine,PMG) in aqueous suspensions of Argentine ...
Self-aggregation behaviour of novel thiosemicarbazone drug candidates with potential antiviral activity
(Royal Society of Chemistry, 2010-06)
The present work aimed to gain further insight into the mechanisms governing the aggregation process of 1-indanone thiosemicarbazone drug candidates. Regardless of the relatively low lipophilicity predicted by theoretical ...
Montmorillonite- hydrothermal carbon nanocomposites: synthesis, characterization and evaluation of pesticides retention for potential treatment of agricultural wastewater
(Elsevier Science, 2020-02-05)
Montmorillonite (M) was modified by addition of hydrothermal carbon (HC) in order to obtain pesticideadsorbent materials. Carbohydrates were used as carbon source, and in some cases, also phosphoric acid wasapplied as ...
Toxicity evaluation of nanocrystalline silver-impregnated coated dressing on the life cycle of worm Caenorhabditis elegans
(Academic Press Inc Elsevier Science, 2020-07-01)
In recent times, however, due to the emergence of bacterial strains with resistance to conventional antibiotics, silver has again gained attention as an alternative for developing new efficient bactericides, including the ...

(Frontiers Media, 2021-12-10)
The emergence of SARS-CoV-2 variants with concerning characteristics to public health has attracted the attention of the scientific community and governments both regionally and globally since the end of 2020. The most ...
Critical Water Activity for the Preservation of Lactobacillus bulgaricus by Vacuum Drying
(Elsevier Science, 2008-12)
Lactobacillus delbrueckkii subsp. bulgaricus was dried under vacuum at different temperatures and its preservation evaluated following three parameters: lag time, percentage of membrane damage and z potential). Microorganisms ...
Interrelations of structure, electric surface charge, and hydrophobicity of organo-mica and –montmorillonite, tailored with quaternary or primary amine cations. Preliminary study of pyrimethanil adsorption
(Elsevier Science SA, 2019-02)
In this work, organo-montmorillonite (organo-Mt) and organo-synthetic mica (organo-mica), obtained by quaternary or primary amine cations (octadecyltrimethylammonium (ODTMA) or octadecyl-amine (ODA), respectively) exchanged ...
A simple and “green” technique to synthesize long-term stability colloidal Ag nanoparticles: Fs laser ablation in a biocompatible aqueous medium
(Elsevier Science Inc, 2018-06)
A comparative study of spectral characteristics, size distribution, composition, morphology and long-term stability of colloidal Ag NPs synthesized by ultrashort pulse laser ablation of a solid target and by chemical salt ...
