Hexagonal ZnO microdisks are grown and then selectively dissolved to form microstadiums. Analysis of the growth and dissolution of the microdisks revealed that they follow a reversed crystal growth mechanism, i.e. aggregation of precursors followed by surface crystallization and extension of ...

This contribution reports new methodology we have developed for the disassembly of 3-D UTL framework into 2-D lamellae followed by structure modification including pillaring. This may be widely applicable, particularly to other zeolites that have D4R units present, and so should have great ...

Atomic-scale molecular dynamics computer simulations are used to probe the structure, dynamics, and energetics of alkylamine self-assembled monolayer (SAM) films on graphene and to model the formation of molecular bilayers and protein complexes on the films. Routes toward the development and ...

We report the synthesis, mechanical properties, and deformation mechanisms of polycrystalline, platinum nanocylinders of grain size d = 12 nm. The number of grains across the diameter, D/d, was varied from 5 to 80 and 1.5 to 5 in the experiments and molecular dynamics simulations, ...

PEGylated chlorin e6 photosensitizers were synthesized with tri(ethylene glycol) attached at the ester bond(s) for a 1:1 conjugate at the 173-position, a 2:1 conjugate at the 152- and 173-positions, and a 3:1 conjugate at the 131-, 152-, and 173-positions. These chlorin sensitizers were ...

A fabrication methodology for 120 nm‐diameter, ‐oriented single crystalline Cu nanopillars which are uniformly implanted with helium is described. Uniaxial compression experiments reveal that their yield strength is 30% higher than that of their unimplanted counterparts. This study sheds ...

A microphotoreactor device was developed to generate bubbles (1.4 mm diameter, 90 μL) containing singlet oxygen at levels toxic to bacteria and fungus. As singlet oxygen decays rapidly to triplet oxygen, the bubbles leave behind no waste or byproducts other than O2. From a comparative study ...
