A New Twist on Receptor Signaling

January 4, 2016

Researchers at Johns Hopkins University have found a direct, significant correlation between structure and activation for FGF receptors in response to FGF ligands. Their findings have been reported in the January 2016 issue of Nature Communications.

An n-type pyromellitic diimide polymer composite with in situ microstructure growth of the common element compound SnCl2 reaches the highest purely n-type polymer composite power factor yet reported.

Enhancing Polymer Thermoelectric Efficiency

May 29, 2015

Johns Hopkins University engineers have demonstrated a record increase in efficiency for an n-type polymer semiconductor through the combination of a new polymer electron-transporting semiconductor and a solid additive.

Viewing Cancer on the Move

October 31, 2014

Johns Hopkins engineers have invented a lab device to give cancer researchers an unprecedented microscopic look at metastasis, the complex way that tumor cells spread through the body, causing more than 90 percent of cancer-related deaths

Configurations of five different (A) Cu-centered and (B) Zr-centered polyhedra, in which the center atoms are the top five atoms with the highest participation fractions for each constituent species. These are representatives of GUMs in this MG. Orange spheres are for Cu atoms and silver ones for Zr atoms.

Soft Spots and Their Structural Signature in a Metallic Glass

September 26, 2014

Jun Ding, a PhD student working with Prof. Evan Ma, has demonstrated a structure-property correlation in metallic amorphous solids. This was achieved in collaboration with Prof. Michael Falk’s group in our department. Their findings were recently published in the Proceedings for the National Academy of Sciences (PNAS).

How Static Charge Affects Organic Transistor Switching Voltages

June 9, 2014

A sideways transistor geometry correlated static charge quantitatively to changes in threshold voltage (VT) without disturbing transistor materials or interfaces, and also showed striking differences among different polymer gate materials. This will indicate more effective gate insulator choices for printed transistors with stabilized, defined VT, and inspire new material structures for other applications.
