The role of chloramine species in NDMA formation
(2018-09)
N-nitrosodimethylamine (NDMA), a probable human carcinogen disinfection by-product, has been
detected in chloraminated drinking water systems. Understanding its formation over time is important
to control NDMA levels in ...
Synthesis and characterization of Cu(II) containing PMMA co-polymer for optical applications
(2007-04-03)
Homogenous, transparent, greenish blue Cu(II)
containing PMMA co-polymer disks were prepared
through the radical polymerization of the Cu(II) methac rylate, MMA and HMA using AIBN as an initiator. The
dependence of the ...
Dye‐sensitized Devices: Photovoltaic and Photoelectrolytic Applications
(2018-11)
Dye‐sensitized approach along with stability and surface robustness in titanium dioxide (TiO2) against photocorrosion and degradation has been widely studied and applied in several important applications. This chapter ...
A Chronoamperometric Screen Printed Carbon Biosensor Based on Alkaline Phosphatase Inhibition for W(VI) Determination in Water, Using 2-Phospho-l-Ascorbic Acid Trisodium Salt as a Substrate
(2015)
This paper presents a chronoamperometric method to determine tungsten in water using screen-printed carbon electrodes modified with gold nanoparticles and cross linked alkaline phosphatase immobilized in the working ...
Estudio quimico de las hojas de tabernaemontana arborea rose
(1986)
From the leaves of Tabernaemontana arborea Rose (Apocynaceae) the triterpenoid lupeyl acetate and the indole alkaloids voacangine, 19 epivoacristine, vobasine and 19R-hydroxiconopharingine have been isolated and identified ...
Electrochemical biosensor for quantitative determination of fentanyl based on immobilized cytochrome c on multi-walled carbon nanotubes modified screen-printed carbon electrodes
(2022)
Fentanyl is a powerful synthetic opioid used to treat severe pain. New administration routes toward its illegal consumption
for recreational purposes pose a growing threat to public health, either due to misuse or abuse ...
N-[3-(Prop-1-yn-1-yl)phenyl]benzenesulfonamide
(2019)
In the title sulfanilamide derivative, C15H13NO2S, which shows significant
activity against Staphylococcus aureus and Escherichia coli, the dihedral angle
between the planes of the aromatic rings is 62.15 (19)° and the ...
1,3-Bis{[(2,6-dimethylphenyl)sulfanyl]methyl}benzene
(2019)
The structure of the title compound, C24H26S2, an example of a pincer ligand with an SCS-chelation motif, illustrates the steric effects of the methyl groups in the thiophenyl rings at the 2- and 6-positions, forcing a ...
Influence of rice field agrochemicals on the ecological status of a tropical stream
(2016-01-15)
Many tropical countries contain a high density of protected ecosystems, and these may often be bordered by intensive agricultural systems. We investigated the chemical and ecological status of a stream connecting an area ...
