A tímida participação da área de química em importantes programas nacionais como o Plano Setorial para Recursos do Mar (PSRM), coordenado pela Comissão Interministerial

Paradoxically, when one considers the sea chemistry knowledge itself, though the Brazilian participation in the generation of original knowledge still lags behind

In order to develop a synthetic approach to gain both eficiency and diversity around the isocoumarin scaffold, it was recently established a parallel solid-phase

An analytical method using solid-phase extraction and liquid chromatography coupled to electrospray ionization tandem mass spectrometry (LC-ESI-MS-MS) was developed

These compounds were characterized on their spectral data basis, mainly one- ( 1 H, 13 C, APT) and two-dimensional ( 1 H- 1 H-COSY, 1 H- 1 H- NOESY, HMQC and HMBC) NMR, and

A transition metal/microwave irradiation (or base) free synthesis of aminopyridines has been accomplished via C-N bond forming reaction between chloropyridine and a variety

The corrosion behavior of polypyrrole on aluminium in sodium chloride medium has been investigated by open circuit potential and electrochemical impedance spectroscopy.. A
