Templated growth of platinum nanostructures
… were synthesized by templating the growth of platinum on treated polymer surfaces and within disk-like aqueous bicellar assemblies. The growth mechanisms of all structures were examined in detail. Platinum hollow nanospheres with uniform shell thickness were prepared by the seeded …

The precipitation of uniform silica particles through the controlled hydrolysis of silicon alkoxides
… are reported and linked to particle growth rates. Seeded growth experiments indicate that reactions between soluble species occur at rates that are independent of the size and number density of the seed particles. Estimates of hydrolyzed alkoxide concentrations based on solution …

Growth and characterization of centimeter-sized crystals of pyridine dodecasil-3C
Hydrothermal seeded growth was used to grow centimeter-sized crystals of the all-silica zeolite ZSM-39, also known as the clathrasil dodecasil-3C (D3C). Through careful optimization of reaction conditions coupled with judicious choice of silica sources, conditions were found that minimize the …

Self-seeded II-V semiconductor nanowire growth by metal-organic chemical vapor deposition (MOCVD)
… building blocks in a range of different devices, growth of nanowire arrays with controlled density, morphology, composition and alignment is necessary. In this thesis, we demonstrate controlled growth of self-seeded III-V binary and ternary nanowires by MOCVD. First, self-seeded binary III-V …

Synthesis and characterization of electronic materials for photovoltaic applications
… to fabricate bulk heterojunction materials via a seeded growth process. Electropolymerizable Schiff base complexes have been designed, synthesized, and utilized as precursors for conducting metallopolymers. The embedded metal centers are used as seed points for direct growth of size-controllable …

Bioenabled Synthesis of Anisotropic Gold and Silver Nanoparticles
… gold nanoparticles. Since the underlying growth mechanism for the biomimetic synthesis of APMNs remains elusive and controversial, the other objective is to elucidate the molecular interactions between inorganic species and biopolymers during the course of NP evolution. Fluorescent …

New thin shell silica particles and HILIC phases for liquid chromatography: synthesis, characterisation and functionalisation
For the past decade, there has been a steady growth of interest in the use of superficially porous particles with a solid core and a porous shell (also known as fused core, core-shell or porous shell) for fast and highly efficient separation of low molecular weight solutes to large and complex …

Cucurbit[n]uril-engineered Nano-constructs for Molecular Sensing
… magnetic nanoraspberry NPs using a one-pot seeded growth method. The obtained nanoraspberry NPs show excellent colloidal stability and high SERS enhancement factors (on the order of 10$^{10}$). By immobilising a dense layer of CB[n]s onto the surface of nanoraspberry NPs, a new type of CB/Au …
