In late April 2021, a helium recovery system was installed for the Chemistry NMR/EPR Facility in Otto Maass and the QANUC high-field NMR facility in Pulp and Paper.  This technology, one of only a few in Canada, allows for up to 90% of the helium used in the facilities to be recycled, thus protecting a valuable, and limited, natural resources, and limited greenhouse gas emissions.  Funding was obtained from the Sustainability Project Fund, the

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.

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. In their recent work, the Ariya’s lab developed a wide range of recyclable nanostructures, which provided promising ultra-trace capabilities for both soluble and insoluble micro- and nano-plastic quantification.

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. Through a clever design, using synthetic articulation of branched miktoarm star polymers, we have developed multi-tasking drug loaded soft nanoparticles, which can sense extra- and intracellular environments.

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).

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.

One of most active research areas nowadays is the use of solar energy to produce hydrogen by so-called “water-splitting” reactions. Dr. Butler has co-authored with colleagues from the U.K. and Pakistan a comprehensive review on this topic entitled “Recent Developments and Perspectives in CdS-based Photocatalysts for Water Splitting”. This review examines recent work in attempts to improve the photocatalytic efficiency and stability of CdS for H2 production from water Journal of Materials A, in press (2020). Dr.
