Air pollution: The silent killer called PM2.5

Millions of people die prematurely every year from diseases and cancer caused by air pollution. The first line of defence against this carnage is ambient air quality standards. Yet, according to researchers from McGill University, over half of the world’s population lives without the protection of adequate air quality standards.

A Sustainable Technology for Quantification of Micro- and Nano-plastics in the Environment

Global plastic productions have increased remarkably over the past few decades. Unwanted plastic inputs, specifically, micro- and nano-plastics, into the environment become emerging concerns across the world. However, the quantitative analysis of micro/nano-plastics still remains a major challenge, especially in the complex environmental matrices.

Intelligent polymeric nanoformulations sense and deliver at precise locations

Delivering active pharmaceutical agents to target sites continues to pose tremendous challenges. Much effort has been devoted to formulating endogenous stimuli-sensitive nanocarriers that could load sufficient cargo, stay intact during their passage to desired locations, and provide controlled release pathways.

Resolution of the Passing of Emeritus Professor Mario Onyszchuk (1930–2021)

With heavy hearts we announce the passing of Professor Mario Onyszchuk on January 1, 2021. Mario was born in 1930 near Lviv in Poland, now a part of Ukraine. He grew up in Montreal, earned a BSc in Chemistry from McGill University in 1951, an MSc from U Western Ontario (1952; C. Sivertz) and a PhD from McGill under Carl Winkler (1954). He then moved to England where he received a second PhD from the University of Cambridge in 1956 (H.J. Emeléus).

New Synthetic Strategies to Mimic Biosynthetic Oxidative Bond-Formation

Cytochrome P450, and related iron-containing oxygenases, catalyze a broad range of oxidative bond-forming processes that create complex natural products. Well-known examples include ‘canonical oxidations’, which convert C-H bonds into their corresponding alcohol derivatives (C-OH) via a classical mechanism of rebound. In these well-known cases, C-H abstraction affords a substrate radical that recombines with the enzyme’s Fe-(III)-OH center to form the new C-OH bond.

NMR facilities managers trying to solve helium problem

Department members Tara Sprules, manager of the national high-field NMR facility QANUC, and Robin Stein, chemistry department (MC2) NMR/EPR manager, have just had an article published in the CIC newsletter about helium. Together, they use about 2900 L of helium annually to make their eight NMR spectrometers function, and recent cost increases have left them feeling nervous about the future.
