Abstract: Various methods of reshaping and recycling thermoset polymers and composites containing thermoset polymers are provided. The methods involve the bond exchange reaction of exchangeable covalent bonds in the polymer matrix with a suitable small molecule solvent in the presence of a catalyst. In some aspects, the methods are applied to a carbon fiber reinforced polymer or a thermoset polymer where the thermoset polymer matrix includes a plurality of ester bonds. Using a small molecule alcohol, the methods provide for recycling one or both of the carbon fiber and the polymer, for welding two surfaces, or for repairing a damaged surface in the materials.

Abstract: Described herein are techniques and systems for online ad campaign pacing. The techniques described herein use budget allocation along with the estimations of bids and response rates. With use of budget allocation, the techniques can use budget pacing to enhance impressions and maximize desired responses, such as desired click-through rates. These techniques focus on enhancing pacing and performance of ad campaigns, such as enhancing performance across distinct and/or unified online ad marketplaces. These techniques are especially useful in the context of a demand-side platform (DSP). In some examples, the techniques assume that impression supply is much larger than advertiser demand for impressions of their ads, so such techniques focus on selecting high performing inventory of ad space. Yet, with such a focus, a smooth or consistent delivery of ads over time is used.

Abstract: Few-walled carbon nanotubes (FWNTs) can be synthesized in a simple chemical vapor deposition (CVD) system using a mixture of methanol and ethanol as the carbon source. In preferred embodiments, the present invention uses an ethanol/methanol mixture as the carbon source so that few walled nanotubes (FWNTs) with high purity can be prepared following a simplified purification process. Under the growth conditions of the present invention, ethanol is believed to act as the carbon source while methanol is believed to act as a “carbonaceous impurity remover” to remove the impurities deposited on a support (e.g., MgO) and thereby hinder the formation of such impurities.
