A Review of Breath Sensing for Disease Monitoring and Diagnosis: Breathomics, Artificial Intelligence, and Nanomaterials for the Future of Medicine

open access: yesAdvanced Sensor Research, Volume 5, Issue 7, July 2026.
Breathomics is established as a non‐invasive diagnostic strategy by combining volatile organic compound biomarkers, nanomaterial‐based sensor arrays, and AI‐driven classification. Key diseases, sensing materials, and analytical challenges are critically compared, revealing how portable, data‐enabled breath platforms are moving toward clinically useful ...

Soot Emission Analysis in Combustion of Biogas Diesel Dual Fuel Engine

open access: yesEnvironmental Science and Sustainable Development, 2017
Soot emission in bio-gas diesel dual fuel engine has been analyzed by numerical simulation with 2-stape soot formation model of Magnussen. The result shows that soot formation mainly occurred in diffusion combustion phase of diesel pilot jet.

Filtered density functions from direct numerical simulation of a reactive jet in cross-flow

open access: yes, 2010
Direct numerical simulation (DNS) with multi-step hydrogen-air chemical kinetics is used to investigate the nearfield of a flame stabilized above a reactive jet in cross-flow (JICF). JICF configurations are typically used where rapid mixing is desirable;

Coming out(side): Challenges and supports experienced by LGBTQ+ undergraduates in field‐based courses

open access: yesEcosphere, Volume 17, Issue 7, July 2026.
Abstract Field‐based education can be an important educational experience for undergraduate students interested in field‐based careers or the natural environment. However, field courses introduce a wide array of variables not found in the traditional classroom that must be considered in terms of student access and inclusion.
