Freeze-Drying of Copper-Oxide-Based Porous Bulk Catalysts for Diesel Soot Combustion [PDF]

, 2005
Porous copper oxide particles were prepared by freeze-drying to serve as bulk catalysts for diesel soot combustion. Frozen particles of aqueous copper sulfate solution mixed with other metal sulfate solutions were dried in a vacuum chamber, and the dried

Curvature and Microenvironment Regulation Enable Robust Seawater Electrochemical Hydrogen Peroxide Synthesis for On‐Site Marine Aquaculture

Interdisciplinary Materials, EarlyView.
This work designs pentagon‐defect‐enriched interconnected spherical carbon (PD/IS‐C) via curvature and microenvironment co‐engineering for seawater H2O2 electrosynthesis. Curvature modulates electronic structure to boost reactivity, while local alkaline microenvironment repels Cl− for enhanced stability, endowing PD/IS‐C with exceptional catalytic ...

A study on the influence of inorganic ions, organic carbon and microstructure on the hygroscopic property of soot [PDF]

Atmospheric Chemistry and Physics
Soot is a crucial component of aerosols in the atmosphere. Understanding the hygroscopicity of soot particles is important for studying their role as cloud condensation nuclei (CCN) as well as their chemical behavior and atmospheric lifetime.

Elucidating the polycyclic aromatic hydrocarbons involved in soot inception

Communications Chemistry, 2023
Polycyclic aromatic hydrocarbons are the main precursors to soot particles in combustion systems. A lack of direct experimental evidence has led to controversial theoretical explanations for the transition from gas-phase species to organic soot clusters.

Influence of primary particle density in the morphology of agglomerates [PDF]

, 2012
Agglomeration processes occur in many different realms of science such as colloid and aerosol formation or formation of bacterial colonies. We study the influence of primary particle density in agglomerate structure using diffusion-controlled Monte Carlo

The Illusion of Structural Order: Evaluating the Suppression of Amorphous Carbon Black Pigment Bands in SSE‐Processed Handheld Raman Spectra

Journal of Raman Spectroscopy, EarlyView.
The handheld Raman with SSE system efficiently mitigates fluorescence; however, it may also bias the Raman response towards graphitic domains in carbon‐based black pigments, thereby concealing amorphous carbon contributions that are critical for pigment type identification.
