Just Squeeze In — Drexel Researchers Discover When Spaces Are Tight, Nature Loosens Its Laws

It turns out that when they’re in a hurry and space is limited, ions, like people, will find a way to cram in — even if that means defying nature’s norms. Recently published research from an international team of scientists, including Drexel University’s Yury Gogotsi, PhD, shows that the charged particles will actually forgo their “opposites attract” behavior, called Coulombic ordering, when confined in the tiny pores of a nanomaterial. This discovery could be a pivotal development for energy storage, water treatment and alternative energy production technologies, which all involve ions packing into nanoporous materials.

In their paper, which was recently published in the journal Nature Materials, the researchers explain how Coulombic ordering in liquid salts starts to break down when ions are confined in small spaces — specifically carbon pores less than a nanometer in diameter. And the narrower the pore, the less the ions adhere to Coulombic ordering. Read the full press release here.

Recipe for Safer Batteries — Just Add Diamonds

Recipe for Safer Batteries — Just Add Diamonds

While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due to short-circuiting in mobile devices. In hopes of preventing more of these hazardous malfunctions researchers at Drexel University have developed a recipe that can turn electrolyte solution — a key component of most batteries — into a safeguard against the chemical process that leads to battery-related disasters.

Read the full article here.

Drexel researchers have reported that adding nanodiamonds to the electrolyte solution in lithium batteries can prevent the formation of dendrites, the tendril-like deposits of ions that can grow inside a battery over time and cause hazardous malfunctions.
