Fe Atoms Accelerator Coupled With Oxygen Vacancies Channel Synergistically Boost OER Performance of Fe‐CoMoO4‐Ov Nanosheets

open access: yesCarbon Energy, EarlyView.
Fe‐CoMoO4‐Ov/NF demonstrates significantly improved OER catalytic performance compared to CoMoO4. Specifically, the introduced Fe atoms act as a promoter for surface reconstruction, significantly reducing the energy required for surface reconstruction to generate FeCoOOH. The oxygen vacancies serve as electron channels between the core Fe‐CoMoO4‐Ov and

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

open access: yesChemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

Release of multicomponent pheromones from porous fibres

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Surface engineering empowers a polymer exclusion net to serve dual functions: physical exclusion and pheromonal release, allowing for pest control in agricultural crops. In previous work, a net woven from porous fibres releasing simple, single‐component alarm pheromones showed promising results in field tests.

Meteorological constraints on oceanic halocarbons above the Peruvian Upwelling [PDF]

open access: yes, 2015
During a cruise of R/V METEOR in December 2012 the oceanic sources and emissions of various halogenated trace gases and their mixing ratios in the marine atmospheric boundary layer (MABL) were investigated above the Peruvian upwelling.

Clathrate hydrate crystallization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.

Contamination of Finescale Strain Estimates of Turbulent Kinetic Energy Dissipation by Frontal Physics

open access: yes, 2022
Finescale strain parameterization (FSP) of turbulent kinetic energy dissipation rate has become a widely used method for observing ocean mixing, solving a coverage problem where direct turbulence measurements are absent but CTD profiles are available ...

The Relative Roles of Different Physical Processes in Unstable Midlatitude Ocean–Atmosphere Interactions

open access: yesJournal of Climate, 2011
Abstract Following Goodman and Marshall (hereinafter GM), an improved intermediate midlatitude coupled ocean–atmosphere model linearized around a basic state is developed. The model assumes a two-layer quasigeostrophic atmosphere overlying a quasigeostrophic upper ocean that consists of a constant-depth mixed layer, a thin entrainment ...

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

On the role of the Southern Ocean in the global carbon cycle and atmospheric CO2 change

open access: yes, 2010
Uncertainty about the causes of glacial-interglacial CO2 variations demonstrates our incomplete grasp of fundamental processes that govern our climate and thus one of the foremost problems in palaeoceanography and Earth System Science regards the ...

Chemical cycling and deposition of atmospheric mercury in polar regions: review of recent measurements and comparison with models

open access: yes, 2018
Mercury (Hg) is a worldwide contaminant that can cause adverse health effects to wildlife and humans. While atmospheric modeling traces the link from emissions to deposition of Hg onto environmental surfaces, large uncertainties arise from our incomplete
