Determination of Paraquat in Real Samples Using a Printed PET‐Based Electrode Modified With Molecularly Imprinted Polymer and Carbonaceous Material

open access: yesElectroanalysis, Volume 37, Issue 12, December 2025.
This study reports the development of an electrochemical sensor printed with graphite‐based ink on a recycled PET substrate. The device was functionalized with a molecularly imprinted polymer (MIP) and multiwalled carbon nanotubes (MWCNTs) for the selective detection of paraquat in water, apple juice, and acerola juice samples, highlighting its ...

Implications of Tobacco Use on Pathogen‐Driven Diseases: A Public Health and Policy Perspective

open access: yesWorld Medical &Health Policy, Volume 17, Issue 3, Page 468-474, September 2025.
ABSTRACT The tobacco epidemic remains one of the most significant global public health challenges, responsible for over 8 million deaths annually, with a substantial portion occurring among non‐smokers exposed to second‐hand smoke. While cigarette smoking remains the most prevalent form of tobacco use worldwide, the rise of electronic nicotine delivery

Environmental racism and air pollution: Pre and post the COVID‐19 economic shutdown

open access: yesReview of Policy Research, Volume 42, Issue 4, Page 949-981, July 2025.
Abstract Decades of research demonstrates that minoritized groups are disproportionately affected by swathes of harmful pollutants, including air pollution, even controlling for low income. Would significantly reducing individual car traffic help reduce the EJ gap?
