The applications of photophoresis expand into the various divisions of science, thus physics, chemistry as well as in biology. Photophoresis is applied in particle trapping and levitation, [3] in the field flow fractionation of particles, [4] in the determination of thermal conductivity and temperature of microscopic grains [5] and also in the transport of soot particles in the atmosphere.

Vector art is ideal for printing since the art is made from a series of mathematical curves; it will print very crisply even when resized. [11] For instance, one can print a vector logo on a small sheet of copy paper, and then enlarge the same vector logo to billboard size and keep the same crisp quality.
A larger number of mRNAs would express a greater amount of protein, and how many copies of mRNA are generated depends on the promoter used in the vector. [12] The expression may be constitutive, meaning that the protein is produced constantly in the background, or it may be inducible whereby the protein is expressed only under certain condition ...
The image processing is carried out using specialized software programs, often run on multi-processor computer clusters. Depending on the sample or the desired results, various steps of two- or three-dimensional processing can be done. In addition, single particle analysis can also be performed in an individual particle mode using an ICP-MS unit.
Some refer to microspheres or protein protocells as small spherical units postulated by some scientists as a key stage in the origin of life. In 1953, Stanley Miller and Harold Urey demonstrated that many simple biomolecules could be formed spontaneously from inorganic precursor compounds under laboratory conditions designed to mimic those ...
It has been found that the combination of emulsifiers might prevent particle agglomeration more efficiently. [10] [11] An SLN is generally spherical and consists of a solid lipid core stabilized by a surfactant. The core lipids can be fatty acids, acylglycerols, waxes, and mixtures of these surfactants.
Photosystem I (PSI, or plastocyanin–ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem I [ 1 ] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ...
A cloning vector is a small piece of DNA that can be stably maintained in an organism, and into which a foreign DNA fragment can be inserted for cloning purposes. [1] The cloning vector may be DNA taken from a virus , the cell of a higher organism, or it may be the plasmid of a bacterium.
