Graphene is considered to be a large aromatic molecule, the limiting case of the family of polycyclic aromatic hydrocarbons. This fascinating two-dimensional material has many potential applications, including field effect transistors (FETs). However, the graphene sheets in these devices have irregular shapes and variable sizes, and contain various impurities and defects, which are undesirable ...
This study describes the phenomena involved during regeneration of an aged industrial hydrodesulfurization catalyst (CoMoP/Al2O3) using a non-thermal plasma at low temperature (200 °C). The changes occurring were studied by characterizing spent, partially, and fully regenerated catalysts XRD, Raman, TEM spectroscopy, coke deposited on surface Laser desorption/ionization time-of-flight mass spec...
Closed, laser-induced optical transitions (“optical cycling transitions”) of molecules can be used for state preparation and measurement in quantum information science sensing. Increasingly complex molecular species supporting provide new capabilities science, it is not clear if there a limit on their size or complexity. We explore Ca–O–L constructs to support the center, Ca, with ligands, L, b...
