Occurrence of bacteria with technological and probiotic potential in Argentinian human breast-milk
(Wageningen Academic Publishers, 2020-03)
Breast milk can be a source of potential probiotic bacteria, but the technological capacity of isolates obtained from this source is not always guaranteed. We aimed at isolating lactobacilli from breast milk samples collected ...
A green single-tube sample preparation method for wear metal determination in lubricating oil by microwave induced plasma with optical emission spectrometry
(Elsevier Science, 2019-04)
A straightforward and rapid single-tube sample pretreatment for wear metals determination in used lubricating oils was developed in this work as an alternative to the reference pretreatment method (ASTM). A D-optimal mixture ...
Tuning the product distribution during the catalytic pyrolysis of waste tires: The effect of the nature of metals and the reaction temperature
(Elsevier Science, 2021-07-15)
Metal catalysts based on Ni, Co, and Pd supported on SiO2 were evaluated in the catalytic pyrolysis of waste tires using pyrolysis experiments coupled to gas chromatography/mass spectrometry (Py–GC/MS) and thermogravimetric ...
Sanitary pads and diapers contain higher phthalate contents than those in common commercial plastic products
(Pergamon-Elsevier Science Ltd, 2019-03)
Sanitary pads and diapers are made of synthetic plastic materials that can potentially be released while being used. This study measured the amounts of volatile organic compounds (VOCs) (methylene chloride, toluene, and ...
Chemical Constituents, Antifungal and Antioxidative Effects of Ajwain Essential Oil and Its Acetone Extract
(American Chemical Society, 2004-06)
GC and GC-MS analysis of ajwain essential oil showed the presence of 26 identified components which account for 96.3% of the total amount. Thymol (39.1%) was found as a major component along with p-cymene (30.8%), γ-terpinene ...
Efecto del catión metálico en zeolitas ZSM-5 como catalizadores en la pirólisis de cáscara de maní
(Instituto Nacional de Tecnología Agropecuaria, 2017-06)
El objetivo de esta investigación fue estudiar el efecto de zeolitas ZSM-5 en la mejora in situ de los vapores pirolíticos de la cáscara de maní. Se sintetizaron dos formas de la zeolita: protónica y metálica, esta última ...
Fractionation process in TREF systems: validation of thermodynamic model and calculation procedure by raman LAM studies
(John Wiley & Sons Inc, 2005-09-21)
In this paper, possible sources for the unexpected distributions of crystalline sequence lengths calculated from temperature rising elution fractionation (TREF) calibration experiments, as reported in a previous work, are ...
Influence of VOC emissions on global warming: mitigation of their impact using ceramic monoliths supported Pt, Mn and Ce catalysts at pilot scale
(Planta Piloto de Ingeniería Química, 2017-03)
The removal of a mixture of volatile organic compounds (CHCl3, methyl ethyl ketone, toluene and xylenes), was evaluated by adapting a commercial exhaust fan with a catalytic system ap-plicable to small and medium enterprises. ...
Kaolin as a Feedstock for a Versatile Synthesis of Composite MFI/MCM-41 with Enhanced Catalytic Properties
