Color charge

Perovskite solar cells are known to belong to the third generation of solar cells. Owing to the ability to change the band gap energy when changing the material composition, it has a high absorption coefficient that reduces manufacturing costs and carrier mobility. and the diffusion length of large charged particles leads to higher efficiency, so compared to other types of solar cells of the same generation such as color sensitive batteries and quantum dot batteries, perovskite batteries have the most application prospects.

Soluble flaxseed gum (SFG) extracted at different temperatures (25, 40, and 60 °C) was analyzed in relation to the yield, polysaccharides and phenolics composition, surface charge, color, and rheological properties. The yield of SFG extract increased as the extraction temperature increased.

In this paper, we study the motion of a color charge in spherically symmetric SU(2) non-Abelian static gauge field configuration, based on the Wong equation system. The expressions of field intensities and the dynamic equations of the color charge motion are identified in the general forms.

Simple and accurate spectrophotometric methods are presented for the determination of five 3-hydroxy-3- methylglutaryl coenzyme-A (HMG-CoA) reductase inhibitors (statins), namely atorvastatin, fluvastatin, pitavastatin, rosuvastatin, and simvastatin, in pharmaceutical preparations. The methods are based on the reaction of drugs as n-electron donor with 7,7,8,8-tetracyanoquinodimethane as π-acceptors to give highly colored complex species. All variables were studied in order to optimize the reaction conditions.

In the present study, two new donor–acceptor–donor-type molecules were synthesized and the electro-optical properties of the resulting monomers and their corresponding polymers were investigated. Thiophene was selected as the donor unit and cycloheptyl- and cyclooctyl- substituted benzimidazoles were used as the acceptor units. The synthesized monomers and their electrochemically obtained polymers were characterized using cyclic voltammetry and UV-Vis spectrometry. The optical band gap values of the polymers were 1.

Visualization of multiple sequence alignments often includes colored symbols, usually characters encoding amino acids, according to some (physical) properties, such as hydrophobicity or charge. Typically, color schemes are created manually, so that equal or similar colors are assigned to amino acids that share similar properties.

Online sorting of tomatoes according to their features is an important postharvest procedure. The purpose of this research was to develop an efficient machine vision-based experimental sorting system for tomatoes. Relevant sorting parameters included shape (oblong and circular), size (small and large), maturity (color), and defects.

The modular producer cell lines present several advantages: they are safer since integration of the vector within the packaging cell line was identified, the duration of the entire development process is much reduced as there is no need for screening and, in addition, production conditions are favorable due to the possibility of pre-adaptation of the master cell line to culture conditions and media. Thus, therapeutic virus production from bench to bedside becomes safer, faster, and cheaper (Coroadinha et al. 2010)....

Drug-Receptor Interaction partial charges. When a hydrogen atom bearing a partial positive charge bridges two atoms bearing a partial negative charge, a hydrogen bond is created. A van der Waals’ bond (B) is formed between apolar molecular groups that have come into close proximity. Spontaneous transient distortion of electron clouds (momentary faint dipole, !!) may induce an opposite dipole in the neighboring molecule. The van der Waals’ bond, therefore, is a form of electrostatic attraction, albeit of very low strength (inversely proportional to the seventh power of the distance).
