Interest in the boron nitride nanotube (BNNT) composites has grown exponentially because of BNNTs’ unique properties. The vast majority of papers have used a BNNT material without identifying its p...

Boron nitride nanotubes (BNNTs) are highly interesting for structural, thermal, and biomedical applications but have, thus, far been limited due to a lack of high-yield methods to produce a purifie...

The effects of crystallinity and molecular weight on the ductile-brittle transition of a semi-crystalline polyamide were de-coupled. Low molecular weight organic acid solutions were used to accelerate the molecular weight degradation of polyamide-11

Graphene oxide (GO) was incorporated into polyamide-11 (PA11) via in-situ polymerization. The GO-PA11 nano-composite had elevated resistance to hydrolytic degradation. At a loading of 1 mg/g, GO to PA11, the accelerated aging equilibrium molecular we

Graphene oxide produced by Tour's method (GO) and GO functionalized with 4-4′ oxydianiline (ODAGO) are incorporated at 0.01 to 0.10 weight percent (wt%) into a polyimide (PI) made from 3,3′-benzophenonetetracarboxylic dianhydride (BTDA) and 4-4

It is well known that acidity, pH, of a solution accelerates the hydrolysis of soluble amides. Here we describe the unexpected result that weak small organic acids at low concentrations hydrolyze a polyamide at rates approximately twice that of a wat

In situ reduction of graphene oxide (GO) at moderate temperatures within a polymer was observed using differential scanning calorimetry (DSC). Comparison of heats of reduction from DSC data in poly(vinylpyrrolidone), poly(vinyl acetate), and poly(vin

The objective of this work was to character- ize and, thereby, achieve a fundamental scientific under- standing at the molecular level of the relationship of the intermolecular forces measured at the nanoscale between an individual nanoparticle and a

Nanocomposites consisting of spherical particles of Ag were prepared using a single step in situ method whereby Ag is introduced into the dissolved polymer via dissolution as the organometallic complex Ag TFA in the same solvent as the polymer. The k

The UV cure kinetics of thick samples composed of a dimethacrylate oligomer, a photobleaching initiator, and in the presence of oxygen are modeled and measured. First, the temporal and spatial variation of initiator concentration and the resulting va
