Diagnostic for the characterization of nanometric structures in high temperature reactive systems

open access: yes, 2008
It is now well know that the fraction of particulate mater in the ambient air defined as ultrafine particles can be considered the most critical for adverse human health effects because of their chemical composition and the ability of these particles to ...

Synthesis of functionalized polyolefins in a new continuous bench‐scale reactor apparatus

open access: yesAIChE Journal, EarlyView.
Abstract In‐reactor functionalized polyolefins (FPOs), produced by molecular catalysts, are a new class of polymer materials with applications ranging from high performance adhesives to bitumen compatibilization. In this work, we disclose a procedure for the synthesis of FPOs in a new Continuous Bench‐scale Reactor Apparatus (COBRA).

Lift-off of non-premixed turbulent CH4 jet flames at elevated pressures

open access: yes, 2017
In this study, the lift-off behavior of non-premixed turbulent jet flames (120 kPa to 500 kPa) is explored at elevated pressures, extending the current knowledge limited to sub-atmospheric and atmospheric pressure conditions. Experiments are conducted in

Novel Non‐Cytotoxic Acylphosphinates and Acylphosphine Oxides Photoinitiators

open access: yesAngewandte Chemie, EarlyView.
Novel acylphosphine oxide (APO) and acylphosphinate photoinitiators based on DPO and DOPO were designed to investigate structure–property relationships including photochemical performance, polymerization efficiency and cytotoxicity. While DPO derivatives showed excellent reactivity, DOPO‐based systems also displayed good efficiency and significantly ...

VALIANT: A Vision‐Authenticity Language Framework Through Integrated Experts and Aligned Numerical‐Textual Descriptors for Citri Reticulatae Pericarpium

open access: yesAdvanced Intelligent Systems, EarlyView.
Visual features, numerical descriptors, and controlled textual attributes extracted from smartphone images of Chenpi are integrated by VALIANT, a tailored multimodal framework for simultaneous storage‐age classification and authenticity verification. The workflow distinguishes genuine products from suspicious standard operating procedure mimics while ...

Laser-induced incandescence in turbulent non-premixed flames at elevated pressure

open access: yes, 2017
There is general interest in understanding sooting behavior in canonical flames at elevated pressures. In this study, a new apparatus is used to evaluate sooting turbulent non-premixed flames at 1 atm and 3 atm, with constant Reynolds number.

The response of premixed flames to pressure oscillations

open access: yes, 2009
International audienceRecent measurements of the direct response of premixed flames to acoustic pressure fluctuations have shed doubt on the validity of analytical models that use irreversible one-step chemistry, and suggest that more realistic chemical ...
