Our planet’s lower atmosphere is one very busy place, chemically speaking, as climate researchers have discovered. They are developing a new appreciation of complex processes such as cloud formation and radiative forcing, which determines how much light from the sun can reach the earth’s surface and how much heat can escape. More specifically, the latest research is beginning to take stock of the many constituents that contribute to these processes.
Rubber polymers have been capturing the attention of chemists and the wider public since at least 1770, when pioneering chemist Joseph Priestley coined the term for a material that could remove lead pencil marks from paper.
Which is cleaner, diesel or gasoline? It’s a complex question. While diesel emits more greenhouse gases per gallon, it is also more energy dense and can result in greater fuel economy, lowering emissions...
Naturally occurring complex molecules make attractive research targets, especially if they have some compelling property like antibiotic behaviour. University of British Columbia chemistry professor Katherine Ryan...
Computer models based on molecular energy budgets have made it easier than ever to imagine the myriad ways a protein structure could be folded. Yet it has still been difficult to determine which of those patterns are stable enough to exist in nature, so that their properties could be studied formally.
Apoisonous plant’s value is in the eye of the beholder and Thapsia garganica has become highly prized by cancer specialists. In the wake of a recently published development by investigators at Queen’s University, many cancer patients could become downright fond of these noxious yellow Mediterranean perennials.
Chemical engineers rely on a wide range of numerical methods to make sense of an otherwise messy physical world. But when these methods are taught to students, they are often presented in an already simplified format, without formal proofs and perhaps even embedded in the complex code of modelling software.
Over the past two decades we have become surrounded by lithium battery technology, some of it almost invisible but nevertheless essential to providing portable power storage that we now take for granted. But turning raw lithium into an appropriate medium for retaining and transferring an electrical charge is a complicated process.
