One hundred years of teaching, research, and innovation in chemical engineering at the Faculty of Chemistry, National Autonomous University of Mexico (UNAM): Birthplace and enduring leadership of the discipline in Mexico

The Canadian Journal of Chemical Engineering, EarlyView.
The teaching of chemical engineering in Mexico started in 1925 at the Faculty of Chemistry (FQ) of the National Autonomous University of Mexico (UNAM). Academic institutions, research centres, chemical companies, technological developments, highly trained personnel, and scientific contributions are part of the legacy from FQ‐UNAM.

DEVELOPMENT AND VALIDATION OF ANALYTICAL METHODOLOGY BY HPLC-IR FOR EVALUATION OF ARTEMISININ ON Artemisa annua L.

, 2015
The aim of this work was to develop and validate an analytical methodology for determination of artemisinin used as antimalaric. The method was based on high performace liquid chromatography, using a CN column with mobile phase composed of methanol : H(2)

Coupled heat and mass transfer in reactive parallel‐plate flow: A perturbative Graetz model with modal symmetry and Arrhenius kinetics

The Canadian Journal of Chemical Engineering, EarlyView.
A perturbative Graetz model describes coupled heat and mass transfer in reactive Couette–Poiseuille flow between parallel plates. Viscous dissipation and heat of reaction produce a small temperature rise, which enhances Arrhenius reaction rates and modestly accelerates axial species conversion in the small‐Brinkman‐number regime.

Synthesis and characterization of polymer networks obtained by conventional radical and RAFT copolymerization processes in supercritical carbon dioxide

The Canadian Journal of Chemical Engineering, EarlyView.
Conventional and RAFT dispersion copolymerizations of HEMA and EGDMA in supercritical CO2 are compared in terms of swelling index (crosslink density), morphology, particle size distribution, and modular differential scanning calorimetry. Abstract The syntheses of net‐poly((2‐hydroxyethylene methacrylate)‐co‐(ethylene glycol dimethacrylate ...

Experimental methods in chemical engineering: Temperature‐programmed desorption—TPD

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed desorption (TPD) characterizes the surface active sites of functional materials, such as adsorbents (metal hydrides, porous carbons, zeolites, metal–organic frameworks, for example) and catalysts. Solids surfaces are pre‐treated to remove moisture, contaminants, and previously adsorbed species, then a probe molecule (NH3$
