Drexel Research Helps Bacteria-Powered Microrobots Plot a Course

A team of engineers at Drexel University recently published research on a method for using electric fields to help tiny bio-robots propelled by flagellated bacteria navigate around obstacles in a fluid environment. These microrobots could one day be used for building microscopic devices or even delivering medication at the cellular level.

Bioprinting Stem Cell 'Building Blocks'

Using a special designed extrusion printer he created to squeeze out a mixture of hydrogel and stem cells, Wei Sun, PhD, Albert Soffa chair professor in Drexel’s College of Engineering, is making strides toward rapid prototyping the building blocks of life. His process, which was recently published in Biofabrication gives scientists a head start at growing living three-dimensional tissues and could one day be used to create micro-organs for research purposes.

Drexel Icarus Interstellar Sets Sights on Local Starship Congress—and Interstellar Travel

The members of Drexel's Icarus Interstellar chapter are making their way towards travel in outer space. But first, they want to reach other national universities.

Microscale 'Transformer' Robots Joining Forces to Clear Blocked Arteries

Swarms of microscopic, magnetic, robotic beads could be scrubbing in next to the world’s top vascular surgeons—all taking aim at blocked arteries.

DoE Taps Drexel to Reduce Water Use in Power Plant Cooling

Recent drought conditions in California have focused attention on the nation’s need to protect its water supply. As a result, the U.S. Department of Energy is looking for a better way to cool off some of the country’s 7,304 power plants—99 percent of which are water-cooled. With DoE support, researchers from the College of Engineer are developing technology that can cool plants with wax instead of water.

Using Viruses To Help Water Blow Off Steam

Legions of viruses that infect the leaves of tobacco plants could be the key to making power plants safer, heating and cooling of buildings more efficient, and electronics more powerful. These tiny protein bundles, which were once a threat to a staple cash crop of the nascent United States in the 1800s, are now helping researchers like Drexel University’s Matthew McCarthy, PhD, better understand and enhance the processes of boiling and condensation.

Researchers Take a Closer Look at How a Material’s Behavior Changes as it Gets Smaller

To fully understand how nanomaterials behave, one must also understand the atomic-scale deformation mechanisms that determine their structure and, therefore, their strength and function. Researchers at the University of Pittsburgh, Drexel University and Georgia Tech have engineered a new way to observe and study these mechanisms and, in doing so, have revealed an interesting phenomenon in a well-known material, tungsten. The group is the first to observe atomic-level deformation twinning in body-centered cubic (BCC) tungsten nanocrystals.
A multi-nozzle 3D printer, invented by Sun's lab, allows researchers to grow living, 3D models of cancer tumors.

Engineering Breakthrough Will Allow Cancer Researchers to Create Living Tumors With a 3D Printer

Drexel’s Wei Sun, PhD, Albert Soffa chair professor in the College of Engineering, has devised a method for 3D printing tumors that could soon be taking cancer research out of the petri dish.

This Drexel Student Group Wants to Go on a Field Trip, and You Won't Believe How Far

Damien Turchi and his colleagues aim to boldly go way, way farther than anyone has gone before — no matter that they're still students at Drexel.

Graphic Design Students Help Solve Farming Challenges in Thailand

Graphic design alumna Krissy Beck traveled to Thailand to help design agricultural tools and techniques for Thai farmers as part of the Drexel Thai Harvest Initiative. Each year, the graphic design program chooses one student to participate in the initiative. Beck, who graduated this past June, said her initial interest in the program came from her friendship with last year's graphic designer for the team, Hannah Olin.

Q&A with Ibrahim Bakir: The Co-op Interrupted by a Coup

Ibrahim Bakir is a mechanical engineering student at Drexel University and an Egyptian national. For the past four months, he has been living with his parents in Cairo while completing a six-month co-op as a trainee in a Johnson & Johnson factory in 6th of October City, a suburb of Cairo.

Sandy damage imaging

Images of the destruction caused by Hurricane Sandy have captured the immense power of what many experts have termed a “superstorm.” These snapshots and videos might not tell the whole story, however. A group of Drexel University engineers are now trying to give rescue and recovery workers a better picture of the storm’s damages that can’t be seen by the naked eye.
