Ting Zhu an associate professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech, is shown with a model of the graphene structure. Georgia Tech's calculations and physical experiments at Rice University led to the conclusion that graphene, the one-atom layer of carbon, is only as strong as its weakest link.

As Strong as its Weakest Link: Experiments Determine Real-world Limits of Graphene

April 29, 2014 Atlanta, GA

Researchers have measured the fracture toughness of imperfect graphene for the first time and found it to be somewhat brittle.

Professor Jennifer Hasler displays a field programmable analog array (FPAA) board that includes an integrated circuit with biological-based neuron structures for power-efficient calculation. Hasler’s research indicates that this type of board, which is programmable but has low power requirements, could play an important role in advancing neuromorphic computing.

Seeing Double: New Study Explains Evolution of Duplicate Genes

April 07, 2014 Atlanta, GA

Researchers have shown that a process called DNA methylation can shield duplicate genes from being removed from the genome during natural selection. The redundant genes survive and are shaped by evolution over time, giving birth to new cellular funct

Figure shows the arrangement of nanoparticles in two neighboring layers of the superlattice, with configurations on the left corresponding to the equilibrium state of the superlattice at ambient conditions, and the ones on the right recorded at the end of the volume compression process. Comparison of the configurations reveals flexure of the ligands and gear-like rotations of the nanoparticles, with the hydrogen-bonds between ligands anchored to adjacent nanoparticles serving as “molecular hinges.” (Ima

Self-Assembled Silver Superlattices Create Molecular Machines with Hydrogen-Bond “Hinges” and Moving “Gears”

April 06, 2014 Atlanta, GA

A new study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied.

Georgia Tech researchers have developed a polymer material that can reliably conduct heat from electronic devices. Shown (l-r) are Thomas Bougher, a Ph.D. student in the George W. Woodruff School of Mechanical Engineering, Virendra Singh, a research scientist in the Woodruff School, and Baratunde Cola, an assistant professor. (Georgia Tech Photo: Candler Hobbs)

Heat-Conducting Polymer Cools Hot Electronic Devices at 200 Degrees C

March 30, 2014 Atlanta, GA

Using nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer.

The scientists programmed the robotic arm to poke the sample with an acupuncture needle.

Robotic Arm Probes Chemistry of 3-D Objects by Mass Spectrometry

March 25, 2014 Atlanta, GA

A new robotic system at Georgia Tech’s Center for Chemical Evolution could soon let scientists better simulate and analyze the chemical reactions of early Earth on the surface of real rocks.
