The Emersion of Low-Profit Limited Liability Companies: A Case Study of the Implementation of Hybrid Organizations in Louisiana and North Carolina
… the low-profit limited liability company (L3C), is a byproduct of the current two options of operating, as a traditional private company or a nonprofit organization, not being an ideal fit for the entities being established by social entrepreneurs.</p> <p>Trying to take advantage of both …

Probing the surface of a heterogeneous catalyst: Double resonance of carbon monoxide chemisorbed on highly dispersed platinum
… observed at 77 K for small Pt particles on which l3CO was chemisorbed. The samples are Pt supported on eta-alumina with Pt dispersions (fraction of the atoms that are on the surface) of 26% and 76%. After cleaning, the samples are exposed to CO enriched to 90% l3C• The l3C NMR is observed …

The characterization of humic substances in seawater
… the acidimetric titration characteristics, the l3C: l2C ratios, and the ultraviolet-visible, fluorescence, and infrared spectra were determined. Molecular weight distributions of coastal and Sargasso Sea fulvic acids were measured by gel permeation chromatography. Structural features were …

Development of novel NMR pulse sequences
… broadband decoupling. Multiple-bond (long-range) l3C-1H scalar coupling correlations can yield important bonding information. When the molecule under scrutiny is devoid of proton spectral crowding, and more sensitive 'inverse' pulse sequence experiments are not available, one may use insensitive …

Synthesis and characterization of fluorinated cellulose derivatives
… ethers. Thermal analysis, solution analysis, and l3C spin-lattice relaxation experiments were used to compare the rod-like and coil-like behavior of the fluorobenzyl cellulose and amylose. Polycaprolactone, PCL, was blended with tri-O-benzylated cellulose with different degrees of fluorination. …
