One century of teaching, research, and innovation in chemical engineering in Mexico: The role of chemical engineering in the background and future of polymer science and industrial production in Mexico

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Timeline of key academic milestones and individuals that shaped chemical engineering at FQ‐UNAM and in Mexico. Abstract One hundred years after the beginning of the teaching of Chemical Engineering in Mexico, which started in 1925 in the former National School of Chemical Sciences, currently Faculty of Chemistry (FQ) at National Autonomous University ...

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

Computational modeling of the rectangular non-aligned multi-injector for efficient fuel mixing in a supersonic combustion chamber

open access: yesScientific Reports
The present investigation examines the usage of rectangular multi-injectors for fuel injection in a supersonic combustion chamber. To evaluate the fuel jet penetration and distribution, a computational method is applied to model the supersonic ...

Captivated by Kinesin

open access: yesCytoskeleton, EarlyView.
ABSTRACT Few proteins have inspired as much curiosity as kinesin. Since its discovery 40 years ago, kinesin has become one of the best understood molecular machines in biology, yet it continues to reveal new questions about how cells organize and move their contents.

A feasibility study on using inkjet technology, micropumps, and MEMs as fuel injectors for bipropellant rocket engines

open access: yes, 2008
Control over drop size distributions, injection rates, and geometrical distribution of fuel and oxidizer sprays in bi-propellant rocket engines has the potential to produce more efficient, more stable, less polluting rocket engines.

Innovation and Growth Investment Through Capital Expenditure as a Channel and Boundary Condition Between Financial Performance and Corporate Reputation

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the role of capital expenditure in the relationship between financial performance and corporate reputation. Using moderation and mediation analyses based on multiple regressions with bootstrapping, we examined data from 121 airlines from 46 countries during 2007–2023.

Large droplet release

open access: yesDroplet, EarlyView.
Curved hydrophobic mesh surfaces enable stable release of large droplets exceeding the capillary length. By tuning surface curvature, porosity, and acceleration, oscillatory breakup is suppressed, producing near‐spherical droplets ideal for high‐precision fluid applications and multiphase flow control.

Carbon emission assessment of tunnel infrastructures: From construction to operation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Direct synthesis of aromatics of jet fuel by integrating CO2-FTS and toluene alkylation reaction [PDF]

open access: yes
Although considerable efforts have been made in CO2 hydrogenation to produce long-chain hydrocarbons through the CO2 Fischer-Tropsch (CO2-FTS) pathway, the selectivity of C8+ hydrocarbons is still low. This work reported a new strategy for the production
