EDUCATION
You would not think of touring a foreign country without a decent phrase book in your hip pocket or, better yet, a good grasp of the local language. Yet many chemistry students stumble into the distinctly foreign territory of organic chemistry with no such preparation.

ANALYTICAL CHEMISTRY
After decades of deliberation and debate, humanity’s efforts to confront climate change remain tangled with a familiar business maxim: you can’t manage what you can’t measure. Although rising levels of greenhouse gases (GHGs) within the Earth’s atmosphere have been repeatedly linked to changing weather...

MATERIALS CHEMISTRY
Daan Maijer points to the wheel mounted behind glass outside his University of British Columbia office and tells me why, exactly, it looks the way it does. All those cutouts and bevels and shapes have practically nothing to do with function and everything to do with looks. “About 20 percent of a person’s reaction to...

It was a steel plant operator’s worst nightmare — a blast furnace that could not be shut down properly. The resulting damage throughout the plant was significant, although its full extent has not been made public. The details were withheld by Germany’s federal office for information security: Bundesamt für Sicherheit in der Informationstechnik (BSI), which...

PETROCHEMISTRY
Fossil carbons — coal, oil, and natural gas — have become a mainstay of modern life. Their principal advantage is they are readily converted into energy (heat and electricity), transportation fuels (gasoline, diesel, etc.) and chemicals (principally fertilizers and petrochemicals). They occur in highly concentrated form but typically in remote and environmentally sensitive regions. With...

Annicia Phu sports a cauliflower ear, a souvenir from her years as a competitive wrestler in high school in Calgary. Jammed fingers and bruises were also commonplace — not only in wrestling but rugby, another full-contact sport she embraced as a student. Besides being “a great way to relieve stress,” the competitions also forced Phu...

INTELLECTUAL MATTERS
In my previous column, I wrote that inventors are generally free to exploit their invention as a result of the state-granted monopoly that patents guarantee. In the field of medicine, however, many jurisdictions have laws or regulations that either limit the price for which the inventor can charge for the medicine or, in some cases,...

CHEMFUSION
A rotten apple spoils the whole barrel. That’s not just an old adage, it’s a scientific fact. And it all has to do with ethylene, a gas produced internally by a fruit to stimulate ripening. Basically, ethylene is a plant hormone. Our word “hormone” derives from the Greek “hormon” meaning “to set in motion” and...
