On-surface synthesis is a powerful method that has emerged recently to fabricate a large variety of atomically precise nanomaterials on surfaces based on polymerization. It is very successful for thermally activated reactions within the framework of heterogeneous catalysis. As a result, it often lacks selectivity. We propose to use selective activation of specific bonds as … Read more

We have synthesized Pt1Zn3/ZnO, also termed 0.01 wt %Pt/ZnO-O2–H2, as a catalyst containing singly dispersed single-atom bimetallic sites, also called a catalyst of singly dispersed bimetallic sites or a catalyst of isolated single-atom bimetallic sites. Its catalytic activity in partial oxidation of methanol to hydrogen at 290 °C is found to be 2–3 orders of … Read more
Dr. Jia Shi, Bushra Ashraf, and Syeda Faiza Rubab Sherazi were selected to attend the School on Electron-Phonon Physics, Many-Body Perturbation Theory, and Computational Workflows. The school will be held June 10-16, 2024 at The University of Texas at Austin. The goal of this school is to introduce participants to first-principles calculations for electron-phonon physics … Read more

Isotope effects have received increasing attention in materials science and engineering because altering isotopes directly affects phonons, which can affect both thermal properties and optoelectronic properties of conventional semiconductors. However, how isotopic mass affects the optoelectronic properties in 2D semiconductors remains unclear because of measurement uncertainties resulting from sample heterogeneities. Here, we report an anomalous … Read more

We investigate the transport properties of a quantum dot coupled to leads interacting with a multispin system using the generalized master equation within the Coulomb blockade regime. We find that if two states for each scattering region electron manifold are included, several signatures of the interacting spin system appear in steady-state transport properties. We provide a … Read more
