The Diverse Modes of Oxygen Reactivity in Life & Chemistry

open access: yesChemSusChem, Volume 15, Issue 24, December 20, 2022., 2022
Breath of life: Oxygen is the quintessential molecule of life on our planet. Three molecular oxygen species dominate natural and artificial oxygenation reactions: the singlet and triplet spin states of dioxygen and ozone. This Review summarizes key applications of these molecular oxygen species in biology, medicine, technologies, and laboratories ...

Recent advances and challenges in temperature monitoring and control in microfluidic devices

open access: yesELECTROPHORESIS, Volume 44, Issue 1-2, Page 268-297, January 2023., 2023
Abstract Temperature is a critical—yet sometimes overlooked—parameter in microfluidics. Microfluidic devices can experience heating inside their channels during operation due to underlying physicochemical phenomena occurring therein. Such heating, whether required or not, must be monitored to ensure adequate device operation.

Ultrathin Gold for Robust Multi‐Element Surface Plasmon Resonance Biosensing

open access: yesAdvanced Materials Interfaces, EarlyView.
This is a pioneering work where for the first time we applied recently synthesised ultrathin layer of gold for plasmonic biosensing that makes use of multi‐element architectures. This study solves the problem of stability of the multi‐element biosensors as well as demonstrates increased sensitivity achieved by utilising new additions to low‐dimension ...

The local health impacts of natural resource booms

open access: yesHealth Economics, Volume 32, Issue 2, Page 462-500, February 2023., 2023
Abstract This paper uses novel micro‐data on natural resources and administrative health data in Brazil to study how economic booms in minerals affect health at birth. By implementing a reduced‐form estimation of shift‐share research designs, the identification strategy relies on the exogeneity of global commodity prices to municipality‐specific health
