Summary of "Surface charging by the cold plasma discharge of lentil and pepper seeds in comparison with polymers."

Cold plasma treatment charges organic surfaces. Surface density of the electrical charge supplied by cold radiofrequency plasma to the pepper and lentil seeds and various polymers: polyethylene, polystyrene, polycarbonate and poly(methyl methacrylate) was established experimentally. The surface charge density for all of studied interfaces, with one exception of polycarbonate was estimated as σ≈0.75-3.7μC/m; for the polycarbonate it was almost an order of magnitude larger, namely σ≈7-9μC/m. The kinetics of the surface charge leakage was studied. The characteristic time of temporal change in the surface density of the electrical charge gained by the seeds is markedly larger than that of synthetic polymers.

A common spice from fruit of PIPER NIGRUM. Black pepper is picked unripe and heaped for a few days to ferment. White Pepper is the ripe fruit dehulled by maceration in water. Piperine is a key component used medicinally to increase gastrointestinal assimilation of other supplements and drugs.

A plant species in the PIPERACEAE plant family. It is a common spice on foods and is used medicinally to increase gastrointestinal assimilation of other supplements and drugs. Piperine is a key component. Black pepper is picked unripe and heaped for a few days to ferment. White Pepper is the ripe fruit dehulled by maceration in water.

Ionized gases, consisting of free electrons and ionized atoms or molecules which collectively behave differently than gas, solid, or liquid. Plasma gases are used in biomedical fields in surface modification; biological decontamination; dentistry (e.g., PLASMA ARC DENTAL CURING LIGHTS); and in other treatments (e.g., ARGON PLASMA COAGULATION).
