A Soft Solution to the Hard Problem of Energy Storage

Recently published research from Drexel University and the University of Pennsylvania, shows a new technique for manipulating two-dimensional materials that allows them to be shaped into films of a practically usable thickness, while maintaining the properties that make them exceptional candidates for use in supercapacitor electrodes.

A High(er)-Definition Nose — Drexel's MXene Material Could Improve Sensors That Sniff

Sensors that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person’s breath. Researchers from Drexel University and the Korea Advanced Institute of Science and Technology have made a discovery that could make our best “chemical noses” even more sensitive.

Drexel Researchers Make a Carbon Nanofiber Supercapacitor (Without The Flammable Ingredients)

A group of Drexel University researchers have created a fabric-like material electrode that could help make energy storage devices — batteries and supercapacitors — faster and less susceptible to leaks or disastrous meltdowns. Their design for a new supercapacitor, which looks something like a furry sponge infused with gelatin, offers a unique alternative to the flammable electrolyte solution that is a common component in these devices.

New Microscope Technology Gives Drexel Researchers a Detailed Look at Structure and Composition of Materials

At their core, electron microscopes work a lot like a movie projectors. A high-powered beam passes through a material and it projects something — usually something we really want to see — onto a screen on the other side. With most electron microscopes, however, capturing data is like trying to project a movie onto a dirty screen that is too small to see the whole projection. But a new camera technology, developed by researchers at Drexel University, is enabling the microscopes to present a clearer, more complete and detailed look at their featured presentation.

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.

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.
