Research describing how an optical field can modify the electronic properties of a solid was recently published in Nature Communications titled "
A research team led by professors from the University of Pittsburgh 
New research from the Giannis (Yanni) Mpourmpakis and his team introduces the first universal adsorption model that accounts for detailed nanoparticle structural characteristics, metal composition and different adsorbates, making it possible to not only predict adsorption behavior on any metal nanoparticles but screen their stability, as well. The research combines computational chemistry modeling with machine learning to fit a large number of data and accurately predict adsorption trends on nanoparticles that have not previously been seen. By connecting adsorption with the stability of nanoparticles, nanoparticles can now be optimized in terms of their synthetic accessibility and application property behavior. This improvement will significantly accelerate nanomaterials design and avoid trial and error experimentation in the lab. Their work was published in Science Advances on Sept. 13, 2019.
The ability to combine continuously tunable narrow-band terahertz (THz) generation that can access both the far-infrared and mid-infrared regimes with nanometer-scale spatial resolution is highly promising for identifying underlying light-matter interactions and realizing selective control of rotational or vibrational resonances in nanoparticles or molecules. Here, we report selective difference frequency generation with over 100 THz bandwidth via femtosecond optical pulse shaping. The THz emission is generated at nanoscale junctions at the interface of LaAlO3/SrTiO3 (LAO/STO) that is defined by conductive atomic force microscope lithography, with the potential to perform THz spectroscopy on individual nanoparticles or molecules. Numerical simulation of the time-domain signal facilitates the identification of components that contribute to the THz generation. This ultra-wide-bandwidth tunable nanoscale coherent THz source transforms the LAO/STO interface into a promising platform for integrated lab-on-chip optoelectronic devices with various functionalities.
The recently published paper in journal of ACS NANO on Ultrafast Microscopy of Spin-Momentum Locked Surface Plasmon Polaritons is an essential research for designing optical elements to control spin-polarized SPP (surface plasmon polaritons) fields on the nano femto scale. Hrvoje Petek and his colleagues have shown two-photon photoemission electron microscopy images formed by coupling and propagation of longitudinal and transverse components of SPP fields of light. Further, they have also shown the spin-momentum locked SPP wave packets launched with circularly polarized excitation propagate at the same phase and group velocities as for the linearly polarized excitation using time-resolved experiments.
Mostafa Bedewy Receives Frontiers of Materials Award
Dr. Mostafa Bedewy was recently selected for the 2022 Frontiers of Materials Award from the Minerals, Metals, and Materials Society.
The award recognizes top-performing early career professionals who are able to organize a Frontiers of Materials symposium on a hot or emerging technical topic at the TMS Annual Meeting & Exhibition.
Dr. Bedewy is an outstanding researcher, and his work in the fabrication of graphene and related carbon nanomaterials directly on polymers enables the development of flexible, wearable electronic devices such as implantable biomedical sensors and bendable batteries. He has won several awards including the 2020 Outstanding Young Investigator Award from the Institute of Industrial and Systems Engineers’ Manufacturing and Design (IISE M&D) Division and the 2018 Outstanding Young Manufacturing Engineer Award from the Society of Manufacturing Engineers (SME).
Congrats Mostafa!
