91滴滴

, 91滴滴鈥檚 Climate Change Artist-in-Residence, will curate the Faculty of Science鈥檚 Bicentennial Science/Art Exposition, billed as a 鈥渃elebration of science in all its forms鈥�.

The art show organizers are calling on all members of the 91滴滴 community to submit works in any medium, expressing what science means to them.

The deadline for submissions is October 31, 2021.

It is with great sadness that we share the news of the passing of Dr. James M. Fresco, a former Associate Professor in the Department of Chemistry, 91滴滴, on Sunday, May 23, 2021, just a few months short of his 95^th birthday.

In late April 2021, a helium recovery system was installed for the in Otto Maass and the in Pulp and Paper.聽 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.聽 Funding was obtained from the Sustainability Project Fund, the

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鈥檚 lab developed a wide range of recyclable nanostructures, which provided promising ultra-trace capabilities for both soluble and insoluble micro- and nano-plastic quantification.

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 91滴滴 in 1951, an MSc from U Western Ontario (1952; C. Sivertz) and a PhD from 91滴滴 under Carl Winkler (1954). He then moved to England where he received a second PhD from the University of Cambridge in 1956 (H.J. Emel茅us).

The Faculty of Science is celebrating 91滴滴鈥檚 200^th anniversary with a student art exhibition on the theme of 鈥淪cience!鈥�. 91滴滴 students at all levels and all faculties are invited to submit works in any medium, expressing what science means to them.

Faculty of Science bicentennial committee member, Torsten Bernhard, says the aim of the exhibition is to celebrate science in all its forms.

One of most active research areas nowadays is the use of solar energy to produce hydrogen by so-called 鈥渨ater-splitting鈥� reactions. Dr. Butler has co-authored with colleagues from the U.K. and Pakistan a comprehensive review on this topic entitled 鈥淩ecent Developments and Perspectives in CdS-based Photocatalysts for Water Splitting鈥�. This review examines recent work in attempts to improve the photocatalytic efficiency and stability of CdS for H₂ production from water . Dr.
