The role of aromaticity in the cyclization and polymerization of alkyne-substituted porphyrins on Au(111)
(2023)Aromaticity is an established and widely used concept for the prediction of the reactivity of organic molecules. However, its role remains largely unexplored in on-surface chemistry, where the interaction with the substrate ... -
Current Chemistry Investigators (CCI): Development and Evaluation of a Scientist in a Classroom Electrochemistry Workshop
(2023)Over the course of the COVID-19 pandemic, school students suffered from a reduction in opportunities to connect with higher education institutions, meet scientific role models in person, discuss scientific career options, ... -
Two-dimensional material inks.

Alcohol Pre-treatment to Eliminate the Interference of Micro Additive Particles in the Identification of Microplastics Using Raman Spectroscopy
(2022)Raman spectroscopy is an indispensable tool in the analysis of microplastics smaller than 20 μm. However, due to its limitation, Raman spectroscopy may be incapable of effectively distinguishing microplastics from micro ... -
Restructuring of emergent grain boundaries at free surfaces – An interplay between core stabilization and elastic stress generation
(2022)Emergent grain boundaries at free surface impact a wide range of material properties but little is known about their atomic-scale behavior. Using scanning tunneling microscopy and calculations, we studied the structure of ... -
Electrochemical Detection of Isolated Nanoscale Defects in 2D Transition Metal Dichalcogenides
