Plasma, the fourth state of matter, is a distinct processing medium for surface treatment and surface modification. This note discusses the nature of plasma and how plasma is formed, its unique advantages, and the types of surface interactions that are possible during plasma treatment. ...
However, it is a relatively simple and low-cost process, making it suitable for certain applications. Dry etching, on the other hand, uses a reactive gas or plasma to remove material from the semiconductor surface. There are several dry etching techniques, including reactive ion...
A plasma cutting machine, or plasma cutter, uses a plasma stream to transfer energy to a conductive work material. The plasma stream is typically formed by forcing a gas such as nitrogen, oxygen, argon — or even air — through a narrow nozzle. An electric current produced by an external ...
A plasmodesma (the singular of plasmodesmata) is made of two components: the membrane and membrane spaces. The membrane part is an extension of the outer covering of the plant cell, the plasma membrane or the cell membrane. The membrane spaces are formed by the endoplasmic reticulum (a cell ...

@gardenturtle: There is a condition called plasma cell myeloma (also known as multiple myeloma, Kahler disease, and myelomatosis). It is a type of cancer that begins in the plasma cells. It occurs when abnormal plasma cells multiply uncontrollably in the bone marrow. ...
Plasma electrolytic oxidation (PEO), also known as micro-arc oxidation (MAO), is a surface coating technology that produces multiple ceramic layers on the surface of light metals, valve metals and their alloys. Uniquely, the porous outer layer enables materials scientists and engineers to impregnate...
CNC Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, aluminum, brass and copper, although other conductive metals may be cut as well. CNC Plasma cutter is often...
What Defines a Cell? Figure 1: Transport proteins in the cell membrane A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment. Each transport protein is specific ...
