Hot Electrons at the Interface between Silver Nanoparticles and a Graphite Substrate

  • By Aude Marjolin
  • 8 May 2017

The interface between nano-sized precious metal clusters such as Silver (Ag) and a semiconductor such as graphite (Gr) is called a heterojunction (Ag/Gr). Heterojunctions have great promise in enhance solar energy conversion due to their unique and enhanced optical, electronic, and chemical properties. When excited with laser pulses, electrons in the system acquire a mean energy higher than its thermal equilibrium value and are referred to as "hot electrons". In fact, graphitic materials are model systems for the study of hot electron dynamics. An ineffective screening within the layers of graphite allows the hot electrons to reach temperatures comparable to that in the solar photosphere!

In a study supported by the Center for Chemistry at the Space-Time Limit recently published in the Journal of the American Chemical Society, Hrvoje Petek and his group modified the Gr surface with Ag nanoclusters (NC)s to investigate how the excitation of the plasmonic resonance of the Ag/Gr heterojunction affects the generation, spatial distributions, and relaxation processes of hot electrons. Plasmonic resonance is a prominent feature of precious-metal nanoparticles; it is a sharp and intense absorption band in the visible range that arise from a collective resonant oscillation of the free electrons of the conduction band of the metal called plasmon.


Graphane as an Efficient and Water-Free Hydrogen Fuel Cell Membrane

  • 8 May 2017

Hydrogen powered fuel cell cars, developed by almost every major car manufacturer, are ideal zero-emissions vehicles because they produce only water as exhaust. However, their reliability is limited because the fuel cell relies upon a membrane that only functions in when enough water is present, limiting the vehicle’s operating conditions. 

Karl Johnson and his group have found that the unusual properties of graphane – a two-dimensional polymer of carbon and hydrogen – could form a type of anhydrous “bucket brigade” that transports protons without the need for water, potentially leading to the development of more efficient hydrogen fuel cells for vehicles and other energy systems. Graduate research assistant Abhishek Bagusetty is the lead author on their paper “Facile Anhydrous Proton Transport on Hydroxyl Functionalized Graphane”, recently published in Physical Review Letters. Computational modeling techniques coupled with the high performance computational infrastructure at the University’s Center for Research Computing enabled them to design this potentially groundbreaking material.

Paul R. Cohen is the founding dean of the University of Pittsburgh School of Computing and Information. The first new school or college established at Pitt since 1995, the School of Computing and Information is a multidisciplinary environment that supports discovery, innovation and entrepreneurship driven by data and technology. It is a key element in Pitt’s strategy to support research in data and computation-intensive fields across the University. The school will begin operations on July 1 and will enroll its first students in the fall 2017 term.Cohen’s deanship begins on Aug. 1, 2017.

Paul is a visionary leader who will quickly drive our School of Computing and Information to the forefront of academic excellence,” said Pitt Chancellor Patrick Gallagher. “He is also an expert collaborator and a leading authority on utilizing data, technology and information in new ways to solve some of the most challenging and complex issues facing society today.”


APS Topical Group on Quantum Information Becomes Division of Quantum Information

  • 5 May 2017

The Topical Group on Quantum Information has officially become the Division of Quantum Information.

The mission of the Topical Group on Quantum Information is to promote the advancement and diffusion of knowledge concerning the physics of quantum information, computing, fundamental concepts, and foundations. The Topical Group will serve as a focus for theoretical and experimental research in these and related areas. Research topics of direct interest include quantum entanglement, quantum communication, quantum cryptography, quantum algorithms and simulations, physical implementations of qubits, quantum error correction, fault-tolerant quantum computation, quantum measurements, open quantum systems, quantum coherence, control of quantum dynamics, the quantum-classical correspondence, and the conceptual and mathematical foundations of quantum theory.

For more information, visit GQI’s official APS-based website. If you are already a member of the American Physical Society, you can join the Topical Group on Quantum Information here, and find out how to join the American Physical Society here.

  • 3 May 2017

Peng Liu has been selected to participate in the 2017 Mentoring Workshop that will take place in Kansas City, MO, June 6-8, 2017.

The Mentoring Workshop for New Faculty in Organic and Biological Chemistry has been held annually and sponsored by National Institute of General Medical Sciences (NIGMS) since 2005. Currently the workshop has trained around 330 new investigators. The workshop aims to mentor assistant professors at the early stage of their careers in NIH proposal preparation, establishment of unique and productive research programs, and development of skills for success in other academic and professional activities other than classroom teaching.
