New microfluidic device delivers mRNA nanoparticles a hundred times faster
An etched silicon and glass wafer on a surface with a quarter beside it for scale.

The researchers’ new platform technology, called Very Large Scale Microfluidic Integration, allows tens of thousands of microfluidic units to be incorporated into a single three-dimensionally etched silicon-and-glass wafer. (Image: Penn Engineering Today)

New microfluidic device delivers mRNA nanoparticles a hundred times faster

With a “liquid assembly line,” Penn researchers have produced mRNA-delivering-nanoparticles significantly faster than standard microfluidic technologies.

Growing ‘metallic wood’ to new heights
A metallic arch on a surface reflecting a rainbow prism.

This strip of metallic wood, about an inch long and one-third inch wide, is thinner than household aluminum foil but is supporting more than 50 times its own weight without buckling. If the weight was suspended from it, the same strip could support more than six pounds without breaking. (Image: Penn Engineering Today)

Growing ‘metallic wood’ to new heights

“Metallic wood” is full of regularly spaced cell-sized pores that radically decrease its density without sacrificing the material’s strength, which not only gives metallic wood the strength of titanium at a fraction of the weight, but unique optical properties.

Paving the way for ‘next-generation’ lithium-ion batteries

A new study from Penn Engineering details the complex electrochemical process that causes certain types of batteries to degrade, insights that could aid in the design of longer lasting, more efficient batteries in the future.

For early amphibians, a new lifestyle meant a new spine

Moving from water to land and back again corresponded with distinct changes in animals’ spinal morphology, according to a new study led by paleontologist Aja Carter.

Engineers pave way for chip components that could serve as both RAM and ROM

The hurdle for making individual chip component devices has always been in manufacturing high-temperature ferroelectric materials. Now a team of researchers at the School of Engineering and Applied Science has shown a potential way around this problem.

A blueprint for designing and synthesizing new, multifunctional materials

By combining theory, computational simulations, chemical synthesis, and assembly, researchers demonstrate how an “inverse design” strategy can create unique materials using difficult-to-mix nanocrystals.
