This text was initially revealed on the College of Science web site.

Dr. Janusz Pawliszyn acquired the Chemical Institute of Canada Medal for his excellent contribution to the science of chemistry in Canada. Sponsored by the Chemical Institute of Chemistry, the CIC Medal is their prime award.

Pawliszyn is a professor within the Division of Chemistry. His analysis focuses on the event and utility of state-of-the-art, built-in and automatic analytical strategies and instrumentation, for on-site evaluation and monitoring. 

He invented the Strong Part Microextraction (SPME) know-how in 1990, a game-changer within the area of analytical chemistry. The outcomes of his analysis result in the elimination of natural solvents from the pattern preparation step and the miniaturization of the sampling units to facilitate on-site monitoring and in-vivo evaluation. SPME is a inexperienced analytical device and initiated scientific curiosity in microextractions. The versatile format of SPME know-how permits the design of units exceeding the efficiency of conventional analytical instruments whereas assembly the targets of worldwide sustainable growth. 

SPME-based applied sciences are used worldwide for the detection of chemical compounds each within the lab and numerous on-site and area functions. When paired with different strategies, SPME know-how can also be used as a well being and security device, enabling fast danger evaluation. Pawliszyn has used SPME to detect pesticides in honey, life within the ocean, doping in sport. SPME can analyze samples on-site, cost-effectively, and with out the usage of polluting solvents or costly labs. SPME can also be versatile, with human well being functions in most cancers detection and drug screening.

“Janusz Pawliszyn’s impact on modern analytical chemistry can be described as truly foundational, with central contributions to detection technologies used around the globe in the chemical, environmental and medical arenas,” stated John Corrigan, Chemistry Chair.

He’s a Canada Analysis Chair and NSERC Industrial Analysis Chair New Analytical Strategies and Applied sciences. He’s a Fellow of the Royal Society of Canada, College Professor and Editor-in-Chief of Traits in Analytical Chemistry and Inexperienced Analytical Chemistry. Earlier this 12 months, he was ranked the second chemist in Canada among the many prime 100 worldwide in Analysis.com’s Rankings of Extremely-Cited Chemists.

He’ll give a plenary lecture on the Canadian Chemistry Convention and Exhibition (CSC 2023) in June.

Pawliszyn is the second Waterloo chemist to obtain this award. Canada Analysis Chair and Waterloo chemist Linda Nazar gained the award in 2019.

OneButtonPIN will increase safety for blind and low-vision tech customers

A smartphone in a woman's hands.

Working carefully with blind and low-vision (BLV) customers, researchers on the College of Waterloo and the Rochester Institute of Expertise have developed a brand new authentication methodology that would assist BLV know-how customers extra securely entry their units. The brand new methodology, OneButtonPIN, permits customers to enter PIN codes utilizing a single giant button and a collection of haptic vibrations.

Folks with BLV often specific frustrations with present authentication strategies corresponding to drawing patterns, fingerprint and face scans, and PIN codes. Some strategies are tough to make use of successfully with out visible information. Others are susceptible to privateness assaults.

OneButtonPIN addresses these safety points through the use of haptic vibrations imperceptible to outsiders. When prompted to enter a PIN code, the person presses and holds a big button on their smartphone display screen. This prompts a collection of vibrations separated by pauses; the person counts the variety of vibrations comparable to the quantity they want to enter, then releases the button and repeats the method till the specified numbers are entered.

Whereas biometrics corresponding to fingerprints and face scans are distinctive and simple to make use of, an individual’s biometrics can’t be modified or reset, explains Stacey Watson, a lecturer in pc science and one of many researchers on the research.

“More traditional forms of entry are vulnerable due to many BLV people’s use of screen reader technology,” stated Watson. “PIN users are vulnerable both to eavesdropping and shoulder surfing attacks, which is where someone nearby can observe a user’s device without their knowledge.”

In a analysis research, 9 BLV members put in OneButtonPIN apps on their telephones. They have been first tasked with getting into randomly generated PINs utilizing the OneButtonPIN methodology a number of occasions, then instructed to make use of the app at the very least as soon as a day for per week as a part of a diary research. The research revealed that OneButtonPIN allowed customers to enter codes with a median of 83.6 per cent accuracy or above, versus 78.1 per cent accuracy utilizing conventional strategies.

The tactic additionally proved to be extremely safe. Within the second stage of the research, 10 sighted members watched movies of individuals utilizing each conventional PIN entry strategies and OneButtonPIN, then tried to guess their PIN codes. Each participant was in a position to efficiently guess customers’ PINs utilizing conventional strategies, however nobody may efficiently guess code enter utilizing OneButtonPIN.

“While OneButtonPIN was designed for BLV people, many users will appreciate the added security,” Watson stated. “When we make things more accessible, we make things more usable for the average user as well.”

The research was revealed within the Proceedings of the ACM on Human-Pc Interplay.

Centre for Educating Excellence to host tutorial abilities workshop

A message from the Centre for Educating Excellence (CTE).

The Tutorial Abilities Workshop (ISW) is an intensive, collaborative studying mannequin that makes use of video-recorded micro-teaching and peer suggestions classes to assist members’ educating reflection and progress.

Get able to sweat it out at UWAG this week

Women sit in a sauna and watch a flatscreen TV screen.

The College of Waterloo Artwork Gallery (UWAG) is inviting members of the neighborhood to point out up and sweat within the identify of artwork and tradition.

“Mobile Sweat is a customized utility trailer that has been converted into a fully-functioning sauna heated by a wood burning stove, and can comfortably seat 6 to 8 people,” says a observe from UWAG. “It is a hybrid sauna inspired by diverse sweat practices found around the world with the goal of promoting social connection and wellness.”

The sauna is provided with a video monitor and can display screen a collection of quick efficiency movies by Norwegian artist Stein Henningsen together with Habitat, Timeline II, and The Boat, in addition to You’ll be able to inform me extra a brand new video by Waterloo-based UWaterloo MFA alumni Lauren Prousky.

Sauna and screenings are free and open to the general public Thursday, February 2 and Friday, February 3 from 12 midday to five:00 p.m. each day.

Individuals are invited to check-in on the College of Waterloo Artwork Gallery between 12 midday and 4:30 p.m. Bathing fits are really useful, however members may expertise the sauna carrying gentle clothes. Sneakers can’t be worn contained in the sauna so think about bringing a pair of flip-flops and a towel. A restricted variety of towels might be obtainable. Coats, clothes, footwear, and different private gadgets can safely be saved on the gallery. Accessible public loos in East Campus Corridor can be found to be used as impromptu change rooms.

Cell Sweat is introduced at UWAG as a lead as much as Artwork Spin’s Public Sweat pageant, going down in March and April 2023.

Artwork Spin is led by the collaborative curatorial duo of Layne Hinton and Rui Pimenta. Since 2009, Artwork Spin has produced a lot of distinctive festivals, group exhibitions, and bicycle-led artwork excursions with the target of exploring artwork in public areas. Notable initiatives embrace in/future, an 11-day multidisciplinary arts pageant on the West Island of Ontario Place in 2016, and Creation:Destruction a part of the Metropolis of Toronto’s 2019 Nuit Blanche all-night artwork occasion. Artwork Spin has been featured within the New York Instances, Globe and Mail, Toronto Star, VICE, and CBC.

“Please join us for an inspirational sweat!” says UWAG.
