Identification of Exhaled Volatile Organic Compounds Biomarkers for Lung Cancer Under Data‐Limited Conditions Using Data Augmentation and Multi‐View Feature Selection

Advanced Intelligent Discovery, EarlyView.
This work introduces a novel framework for identifying non‐small cell lung cancer biomarkers from hundreds of volatile organic compounds in breath, analyzed via gas chromatography‐mass spectrometry. This method integrates generative data augmentation and multi‐view feature selection, providing a stable and accurate solution for biomarker discovery in ...

Enhanced Resolution in EPR Spectroscopy Using para‐Hydrogen Matrices

Angewandte Chemie International Edition, EarlyView.
We demonstrate the advantageous properties of solid para‐hydrogen (p‐H2) matrices for electron paramagnetic resonance (EPR) spectroscopy by investigating the 2,2,6,6‐tetramethylpiperidinyloxyl (TEMPO) radical and an in situ generated P‐centered mono‐radical.

Lipase‐Mediated Synthesis of Biodiesel Using Blended Alcohol in a Packed‐Bed Reactor System

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The use of lipases in biodiesel production has gained attention as a more sustainable and efficient alternative to chemical catalysts, attributed to their operational reusability and minimal environmental impact. As an innovative approach in this study, a blended alcohol composed of 20 mol% methanol and 80 mol% 1‐butanol was employed as the ...

Analytical Investigation of TAR for Enhancing Performance Using Varied Stack configuration and Varied Working Fluid

International Journal of Applied Mechanics and Engineering
Thermoacoustic cooling, which uses sound waves to transfer heat, is an environmentally friendly and simple alternative to conventional refrigeration. Gas mixture adjustment to improve cooling performance is understudied compared to pure gas use. Previous
