Theoretical analysis reveals a complex oscillatory decay in the diffusivity of {100}-epitaxially supported fcc metal nanoclusters (NCs) with increasing size. NCs have a 3D structure for weak adhesion to oxide or other supports.
Results contrast traditional assumptions of monotonic decay with increasing size.
Results contrast traditional assumptions of monotonic decay with increasing size.
Applications are accepted through Friday, May 29 for a growth opportunity specifically for women* who are Iowa State University Faculty & Staff.
The process for requesting off-site equipment approval has moved to ServiceNow.
A new catalyst that allows using water instead of organic solvents in C-C bond forming reactions is presented. A simple method is developed for regulating the dielectric properties of solid-liquid interfaces. This approach can decrease the environmental impact of catalytic conversions.
We have proved that polyethylene (PE) threads into silica pores, demonstrated that pores induce all-anti conformation of PE, and described in-and-out polymer motion and its energetics.
Selective catalytic hydrogenolysis provides high-quality, value-added liquid products from polyethylene, enabling upcycling of an untapped feedstock
Developed a boron-alkylated BODIPY single-molecule-localization-microscopy (SMLM) probe that is photoactivated with a single low-power visible laser. Nucleophile-containing compounds can be bound to the probe for super-resolution imaging of cellular structures.
Theoretical analysis of the stability of M3S3 complexes on various metal M surfaces, and development of a framework to systematically compare this with the gas-phase behavior.
Understanding the atomic-scale distribution of surface-bound sites is of fundamental importance for rational design of catalysts and other functional materials, yet remained a challenge for spectroscopists.
Metal acetate compounds mediate methane activation; this together with the new oxidative carbonylation suggests new approaches for CH4 utilization in chemical synthesis.
