Microplastics could make other pollutants more harmful

Microplastics — small plastic pieces less than five millimeters in length — are becoming a ubiquitous ecological contaminant. Studies suggest that on their own, these tiny bits are potentially harmful, and it’s unclear what effect they could have on pollutants that latch onto them. Now, res ... more

Putting the brakes on lithium-ion batteries to prevent fires

Lithium-ion (Li-ion) batteries are used to power everything from smart watches to electric vehicles, thanks to the large amounts of energy they can store in small spaces. When overheated, however, they’re prone to catching fire or even exploding. But recent research published in ACS’ Nano L ... more

Storing hydrogen fuel in salts — a step toward ‘cleaner’ energy production

Hydrogen gas could someday replace fossil fuels as a “clean” energy source, producing only water and energy. However, handling large quantities of gaseous hydrogen is cumbersome, and converting it to a liquid requires vessels that can withstand extremely high pressures. Now, researchers rep ... more

Why is Olive Oil Awesome?

Whether you sop it up with bread or use it to boost your cooking, olive oil is awesome. But a lot of chemistry goes on in that bottle that can make or break a product. Take the “extra virgin” standard: Chemistry tells us that a higher free-fatty-acid content leads to a lower grade, less tas ... more

Detecting nerve agents with the touch of a finger

There’s a reason why farmers wear protective gear when applying organophosphate pesticides. The substances are nerve agents that are very effective at getting rid of unwanted bugs, but they can also make humans sick. Even more potent, related compounds -- organophophate nerve agents -- are ... more
