Characterizing ozone production in the Mexico City Metropolitan Area: a case study using a chemical transport model [PDF]

Atmospheric Chemistry and Physics, 2007
An episodic simulation is conducted to characterize midday (12:00–17:00 CDT) ozone (O3) photochemical production and to investigate its sensitivity to emission changes of ozone precursors in the Mexico City Metropolitan Area (MCMA) during an " ...

Sustainable Phosphorylated Cellulose Nanocrystals: A Dual‐Affinity Platform for High‐Efficiency Enrichment of Intact Glycopeptides and Phosphopeptides

Advanced Science, EarlyView.
AAA ABSTRACT Protein glycosylation and phosphorylation are critical post‐translational modifications (PTMs) governing nearly all cellular functions, yet their analysis remains challenging due to reliance on costly and unsustainable enrichment materials.

Ozone/Thiosulfate-Assisted Leaching of Cu and Au from Old Flotation Tailings

Molecules
The growing demand for metal production promotes the search for alternative sources and novel modalities in metallurgy. Flotation tailings are an important secondary mineral resource; however, they might pose a potential environmental threat due to ...

Radiation‐Resistant Kr‐Selective MOF With Record Kr/Xe Selectivity at Elevated Pressure

Advanced Science, EarlyView.
ABSTRACT The separation of Kr/Xe from spent nuclear fuel off‐gas is critical, yet most current adsorbents exhibit Xe‐Kr co‐adsorption under elevated pressures, posing challenges for industrial pressure swing adsorption processes. Herein, we present and evaluate a metal‐organic framework, CALF‐20M‐w, engineered for molecular sieving separation of Kr/Xe ...

In Situ Elucidations of the Mechanism for Inert Molecular N2O Decomposition at Low Temperature Catalyzed by High‐Index Interfacial Exposed Co3O4

Advanced Science, EarlyView.
This study develops a co‐precipitation followed by hydrothermal synthesis strategy for synthesizing Co3O4 catalyst with multiple high‐index facets. Experiments and density functional theory calculations demonstrate that Co3+ on the (400–400) facet can form a novel active Co3+‐O* motif during the reaction.

Life cycle analysis for the cultivation and combustion of miscanthus for biofuel compared with natural gas [PDF]

, 2008
As negative environmental and economic impacts of fossil fuels have escalated, so has the importance of renewable bioenergy crops whose feedstocks are noncompetitive with food supplies. Compared with fossil fuels, use of lignocellulosic feedstocks offers

Oxidation of clofibric acid in aqueous solution using a non-thermal plasma discharge or gamma radiation

, 2017
In this work, we study degradation of clofibric acid (CFA) in aqueous solution using either ionizing radiation from a $^{60}$Co source or a non-thermal plasma produced by discharges in the air above the solution.

High‐Performance Recycling Biobased Photopolymers for 3D Printing

Advanced Science, EarlyView.
By using biobased phenols like eugenol, novel biobased photopolymers containing dissociative phenol‐carbamate bonds are designed for 3D printing. Meanwhile, a “mixed‐monomer assisted recycling” strategy is proposed to recycle the materials. The resulting materials not only achieve high‐performance and excellent chemical recyclability simultaneously ...
