CO oxidation is used for testing the catalytic activity to design new catalytic materials. However, because of low abundance of precious metals in the earth, it is probably not realistic to use precious metal-based catalysts at an industrial scale for CO oxidation. Therefore, there have been continuous efforts towards searching catalysts made of earth-abundant elements for CO oxidation. In the recently published paper in Journal of Phys. Chem. Chem. Phys., Judith Yang and colleagues have shown CO oxidation on cobalt oxides via ambient pressure X-ray photoelectron spectroscopy (AP-XPS), demonstrating the transition of the active surface phase of a transition metal oxide-based catalyst under catalytic conditions with no change in the bulk phase of the catalyst.
PQI always assists to organize an educational and informative visit in the development of Quantum Science, encouraging the collaborations between various industry and academia.
On March 9th, 2018, four students and one postdoc from University of Pittsburgh were invited to visit Google Quantum-Hardware lab at UC Santa Barbara which was organized by PQI. Eric Ostby and Pedram Roushan, Research Scientists at Google were helped us to arrange this visit.
Google's research team do work hard to build a quantum computer which will be millions of times more powerful than today’s supercomputers. Such visit helps to initiate more academic people to get involved in such projects, playing a hub role for quantum technologies.
Ionic liquids (ILs) have attracted tremendous attention for their potential use as materials for carbon capture and sequestration. The excitement for the use of ILs for carbon capture is motivated by the fact that CO2 has greater solubility in common ionic liquids than other small-molecule gases common in air, such as N2. Recently, S. G. Roe and their colleagues have shown, in the journal of Physical Chemistry Letters, the molecular dynamics simulations of CO2 in an imidazolium-based ionic liquid which reveal new insights into the mechanism of CO2 solvation. They have found that the solvent cage evolution of N2 is similar to that of CO2 with no atomic charges, implying that the weaker quadrupole of N2 is responsible for its higher diffusion and lower absorption in ionic liquids.
Recently in the Journal of ACS Nano, R. M. Feenstra, S. K. Fullerton and colleagues have demonstrated the device-ready synthetic tungsten diselenide (WSe2) via metal−organic chemical vapor deposition. This work is a breakthrough in the knowledge for vapor phase epitaxy of epitaxial 2D films on sapphire or other insulating, crystalline substrates. Further, these findings guide and stimulate research interests in synthesis and transport of 2D epitaxial layers for electronic applications.
The development of doping studies has provided an efficient route to tune and improve the properties of the 2D materials. However, the impact of the doping on the structural, electronic, and photonic properties of in situ-doped monolayers remains unanswered due to challenges including strong film substrate charge transfer and difficulty to achieve doping concentrations greater than 0.3 at%. Recently, Susan Fullerton-Shirey and their colleagues have reported in situ rhenium (Re) doped synthetic monolayer MoS2 with ≈1 at% Re, in the Journal of Advanced Functional Materials. They have also discussed the structural and photonic response of doped monolayer MoS2.
Introduction: In the halls of Congress there is widespread agreement about the role of R&D in the success of the America’s most innovative corporations. However, too often lawmakers view government models of discovery, from NASA to public university research labs, as obsolete and costly superstructures in today’s .com marketplace. What happened to the case for public exploration and discovery and why shouldn’t the private sector be trusted to find the cure for Grandma’s dementia or Johnny’s brain tumor? Long-time Washington political insider, former lobbyist, Administration appointee, and AIMBE’s Executive Director, Milan Yager, will reveal the hidden truth about why Congress doesn’t fund needed biomedical research.
Results and Discussion: This presentation will highlight innovations and achievements made possible from past federal investments in basic research; such as the internet, wireless communications, even mapping the human genome. Today, Congress seems less interested in past accomplishments as they assume new priorities to balance the budget, reduce government, and free the private sector to assume long-standing government responsibilities for innovation and discovery. How did Congress make spending decisions to permit federal R&D spending to be flat for over a decade? Learn about why Congress is no long accountable for reduce investments in basic research. Discover three secrets to making a winning case for federal funding for medical and biological research. Learn practical steps to successfully getting your point across to a Member of Congress. Find out how to brand your research as the Sputnik in the race to cure cancer, manage chronic disease, or Type I diabetes.
Conclusions: Arming yourself with the strategies for the political warfare in the case for innovation is more than just changing public policy; it can provide the key to changing the future landscape of new biomedical materials, products or procedures. Attendees will get insight into America’s next biomedical “moonshot” initiative.
Owing to high surface to volume ratios and chemical potential, nanoparticles possess unique optical, electrical, and thermal properties, which constitute the basis of novel applications in sensing, catalysis, nanoelectronics, bio-tagging etc. Despite the great advances in the synthesis, the total structure determination of nanoclusters still remains to be a major challenge. Recently Hyung J. Kim and their colleagues have reported the synthesis and crystal structure of a nanocluster composed of 23 silver atoms capped by 8 phosphine and 18 phenylethanethiolate ligands in the journal of Nature Communications.
