Since 1951, industry lighting professionals have made Hapco their trusted source for aluminum and steel light poles and accessories.

Sep 16, 2007 · We report a dramatic improvement in the preparation of single-walled carbon nanotube solutions based on the ability of specific aromatic polymers to efficiently disperse certain nanotube species...

HiPco SWCNT represent a benchmark for small diameter nanotubes both in the academic community and for industrial and commercial applications. We offer three grades of purity for this unique material. Raw HiPco SWCNT contain up to 15% of iron, whereas Purified HiPco SWCNT and Superpurified HiPco SWCNT contain less than 10 and 5% iron respectively.

Dec 31, 2020 · To this end, we replaced the parameters determining the peak positions of each chirality (i.e., E 11 and E 22) by the empirical relations, and we simultaneously fitted the EA and HiPco SWCNT PLE maps to provide the required broad diameter distribution.

Jan 1, 2021 · This study is performed on a broad diameter distribution sample, and on two chirality-enriched samples whose chirality distributions are determined by photoluminescence excitation spectroscopy (PLE) and statistical analysis of high resolution TEM (HRTEM) images.

Feb 2, 2015 · Using infrared photoluminescence-excitation (PLE) spectroscopy, which resolves each individual type of semiconducting SWCNT 13 (with their diameters and chiral structures indicated by their...

Figure S2: PLE map of the HiPco 195.2 batch. The white squares indicate the integration regions for the different SWCNTs present in the sample to obtain figure S3. Figure S3: Analysis of the PLE maps, by integrating over well-defined emission-excitation intervals (see figure S2). Intensities are presented as a function of diameter.

These scientific findings contribute to a more comprehensive understanding of the assembly process of inhomogeneous SWCNTs within confined interfaces and lay an important foundation for the optical and electronic applications of small-diameter HiPCO s-SWCNTs.
