The next technology talent shortage predicted to be in the area of Quantum Computing

The New York Times featured a story that predict the next tech talent shortage to be in the area of Quantum Computing. A growing concern among American businesses and universities is that unless policies and priorities change, they will have trouble attracting the talent needed to build quantum technology. Last month, the White House Office of Science and Technology Policy invited experts from government, industry and academia to Washington for a daylong policy meeting dedicated to quantum technologies. Several attendees expressed concern that the current administration’s immigration policies could affect quantum research in academia and corporations.


Randall Feenstra receives 2019 Davisson-Germer Prize for pioneering developments of spectroscopic scanning tunneling microscopy

Randall Feenstra receives 2019 Davisson-Germer Prize, which recognizes outstanding work in atomic physics or surface physics. Randy was awarded for pioneering developments of the techniques and concepts of spectroscopic scanning tunneling microscopy. The prize consists of $5,000 and a certificate citing the contributions made by the recipient or recipients. This Prize was established in 1965 by AT&T Bell Laboratories (now Bell Laboratories, Alcatel-Lucent Technologies) and with additional support from the Chope Family Trust.

Karl Johnson and his team discovered a new material that remove carbon dioxide from the air and convert it into useful chemicals

  • 12 October 2018

Karl Johnson and his team worked with a class of nanomaterials called metal-organic frameworks or “MOFs,” which can be used to take carbon dioxide out of the atmosphere and combine it with hydrogen atoms to convert it into valuable chemicals and fuels.

Their findings were published in the Royal Society of Chemistry (RSC) journal Catalysis Science & Technology. The journal featured their work on its cover, illustrating the process of carbon dioxide and hydrogen molecules entering the MOF and exiting as CH2O2 or formic acid—a chemical precursor to methanol. 


John Keith and collaborators discovered a liquid polymer capable of freezing water at room temperature

John Keith and collaborators discovered the unique behavior of a liquid polymer capable of freezing water at room temperature. When a particular polymer—known as polyoxacyclobutane (POCB)— is mixed with water, it raises the mixture’s freezing point from 32 degrees Fahrenheit to about 100 degrees Fahrenheit. Keith and colleagues used computer modeling to find a stable hydrate structure where water molecules thread themselves throughout the polymer to form hydrogen bonds that hold the material together like tiny zippers. Their findings are published in the American Chemical Society (ACS) journal Macromolecules.

Kenneth Jordan will be honored for his contributions to Computational and Theoretical Chemistry in a two-day symposium titled "Electron-Molecule & Molecule-Molecule Interactions". The symposium is co-sponsored by the COMP and PHYS divisions of ACS and will be held during the Spring 2019 ACS meeting in Orlando, FL. The symposium will be for two full days from March 31 to April 1, 2019.


Zachary Ulissi developed a machine learning system to discover new materials for electrocatalysis

Zachary Ulissi and his team developed a machine learning system to search through millions of intermetallics to discover new materials for electrocatalysis.

Typically, catalysts are discovered through trial and error coupled with chemical intuition. Now, an automatic machine-learning framework has been developed that can guide itself to fnd intermetallic surfaces with desired catalytic properties.

Through their study, published in Nature Catalysis, they have a list of materials and intermetallic combinations that experimentalists should try, both for hydrogen evolution and carbon dioxide reduction. The experiments will then determine what will make good electrocatalysts for the large scale.

Single-shot condensation of exciton polaritons and the hole burning effect

  • By Leena Aggarwal
  • 10 September 2018

The single-shot measurements offer a unique opportunity to study fundamental properties of non-equilibrium condensation in the presence of a reservoir. David Snoke and his colleagues have recently reported an insight into spontaneous condensation by imaging long-lifetime exciton polaritons in a high-quality inorganic microcavity in a single-shot optical excitation regime, without averaging over multiple condensate realisations. The results are published in the Journal of Nature Communications. They have demonstrated that how condensation is strongly influenced by an incoherent reservoir and that the reservoir depletion, the so-called spatial hole burning, is critical for the transition to the ground state.
