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

open access: yesJournal 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.

Predictions of soot formation in burner-stabilized stagnation flames using various reaction mechanisms

open access: yesJournal of Thermal Science and Technology
To clarify the effects of reaction mechanisms on soot formation, a two-dimensional numerical simulation was performed for a burner-stabilized stagnation flame.

Carbon deposition model for oxygen-hydrocarbon combustion. Task 6: Data analysis and formulation of an empirical model [PDF]

open access: yes
The formation and deposition of carbon (soot) was studied in the Carbon Deposition Model for Oxygen-Hydrocarbon Combustion Program. An empirical, 1-D model for predicting soot formation and deposition in LO2/hydrocarbon gas generators/preburners was ...

Ten‐year outcomes of combined ACLR and lateral extra‐articular tenodesis: A systematic review

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This systematic review evaluates long‐term outcomes after anterior cruciate ligament reconstruction (ACLR) with lateral extra‐articular tenodesis (LET), including patient‐reported outcome measures (PROMs), failure rates, objective knee scores and radiographic osteoarthritis (OA).

Shock-tube measurements of carbon to oxygen atom ratios for incipient soot formation with C2H2, C2H4 and C2H6 fuels [PDF]

open access: yes
The critical atomic carbon to oxygen ratios, Phi sub C, for incipient soot formation in shock heated acetylene, ethylene, ethane/oxygen/ argon mixtures was measured over the temperature range 2000 K to 2500 K for reactant partial pressures between 0.1 ...

In cylinder visualization of stratified combustion of E85 and main sources of soot formation [PDF]

open access: yes, 2015
The combustion process and soot formation in spark ignited spray guided stratified combustion of E85 was investigated in a single cylinder optical engine with direct injection of fuel using an outward opening piezo actuated injector. The effect of engine

Flame‐Assisted Modification of Glass Wettability: Preliminary Results

open access: yesMacromolecular Symposia, EarlyView.
ABSTRACT Fog formation and moisture condensation limit the performance of glass surfaces in optical, microfluidic, and sensing applications, where stable transparency under humid conditions is essential. Enhancing surface wettability represents an effective strategy to mitigate these effects; therefore, the development of methods to tailor glass ...

Detailed kinetic modeling of soot formation at lightly sooting conditions

open access: yes, 2017
Soot particles formed in combustion processes are well-known for their negative effects, but their formation is still elusive and challenging. In particular, the main chemical and physical pathways are not fully understood. It is important to characterize soot not only in terms of mass yield but also to accurately characterize number density and ...
