LiPo batteries dataset: Capacity, electrochemical impedance spectra, and fit of equivalent circuit model at various states-of-charge and states-of-health.

This dataset contains experimental data of capacity and electrochemical impedance of five Lithium Polymer (LiPo) batteries (model LP-503562-IS-3 manufactured by BAK Technology). All batteries have been subjected to hundreds of charge-discharge cycles to obtain their characteristics at different states-of-health. Capacities have been measured under both standard and stress conditions. At fixed intervals (45 cycles in most cases) batteries have been subjected to partial discharge cycles to measure impedance spectra at different values of the state-of-charge. Impedance spectra have been fitted by using an equivalent circuit model; estimated circuit parameters are included in the dataset.

Push-pull amino succinimidyl ester thiophene-based fluorescent dyes: synthesis and optical characterization.

The design and synthesis of new fluorescent dyes with emission range at 490-650 nm are described. Their structural and electronic properties have been characterized by both experimental techniques and quantum-chemical calculations. The chromophores are donor-π-bridge-acceptor push-pull compounds with a π bridge of phenyl and thiophene rings and their combination. Compared with previous thiophene fluorophores, these dyes show significant redshift in the absorption and emission spectra and offer compact, red-emitting fluorophores. The dyes have amino succinimidyl active ester and can be readily conjugated to proteins, polymers and other amino-group-containing materials.

Testing oligothiophene fluorophores under physiological conditions. Preparation and optical characterization of the conjugates of bovine serum albumin with oligothiophene N-hydroxysuccinimidyl esters.

Bovine serum albumin (BSA) was reacted with linear and newly synthesized branched oligothiophene N-hydroxysuccinimidyl ester fluorophores (TSEs) in moderately basic carbonate buffer solution. Optically stable BSA-TSE conjugates were obtained with a degree of labeling depending on experimental conditions. Conjugates with high fluorophore to BSA ratios (F/BSA = 8) displayed fluorescence quantum yields in the range of 10-30% in water at pH = 7.2, comparable to the quantum yield (25%) of the BSA-FITC conjugate prepared under the same conditions and with the same degree of labeling.
