Synthesis, purification and characterization of carbon dots from pyrolytic carbon black recovered from waste tires
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-11-06)
Pyrolysis is a feasible solution for environmental problems related to the inadequate disposal of waste tires, as it leads to the recovery of pyrolytic products such as carbon black, liquid fuels and gases. The characteristics ...
Do changes in carbon allocation account for the growth response to potassium and sodium applications in tropical Eucalyptus plantations?
(OXFORD UNIV PRESSOXFORD, 2012)
Understanding the underlying mechanisms that account for the impact of potassium (K) fertilization and its replacement by sodium (Na) on tree growth is key to improving the management of forest plantations that are expanding ...
Highly sensitive sensing of food additives based on fluorescent carbon quantum dots
(Elsevier B.V., 2021-04-15)
A robust fluorescence-based sensing strategy was designed considering relevance of analyzing chemical additives in industrialized food. In this study, a sensing approach was developed using fluorescent carbon quantum dots ...
Screen-printed carbon electrode modified with poly-L-histidine applied to voltammetric determination of chromium (VI)
(2006-12-01)
The present work reports the use of a screen-printed carbon electrode (SPCE) modified by poly-L-histidine film to determine chromium (VI). Stable films can be formed by direct addition of PH solution 1 % (w/v) on the ...

Reactivity of the carbon-carbon double bond towards nucleophilic additions. A DFT analysis
(PERGAMON-ELSEVIER SCIENCE LTD, 2004-07-26)
The global and local electrophilicity indexes have been used to characterize the reactivity pattern of the C=C double bond towards nucleophilic addition reactions. A wide family of molecules including ketones, esters, ...
