Gaseous chemistry for a Titan's atmospheric plasma experimental simulation [PDF]
, 2010 We present the first study of gaseous composition monitoring for the PAMPRE experiment, which simulates Titan's atmospheric chemistry by radio-frequency N 2-CH 4 plasma. Methane consumption is quantified for various N 2-CH 4 gas mixtures.

Ultrafast Laser Synthesis of Zeolites
Advanced Materials, EarlyView.The study presents a novel ultrafast laser‐driven synthesis technique for zeolites directly in liquid. Laser pulses create a microscopic reactor that controls reaction kinetics at femto‐ and picosecond timescales. Nonlinear light‐matter interactions drive nucleation and growth, allowing the process to be paused at any stage of self‐assembly.

Gas-liquid chromatography-mass spectrometry of synthetic ceramides containing phytosphingosine
Journal of Lipid Research, 1970 Ceramides containing phytosphingosine as base and one of the fatty acids 16:0, 18:0, 20:0, 22:0, 23:0, and 24:0, were prepared by direct coupling in the presence of a mixed carbodiimide. The ceramides were analyzed as the 1,3,4-tri-O-trimethylsilyl ether
