After the 17th-century introduction by ... | https://en.wikipedia.org/wiki/Synthetic_geometry |
Synthetic immunology is the rational design and construction of synthetic systems that perform complex immunological functions. [ 1 ] Functions include using specific cell markers to target cells for destruction and or interfering with immune reactions.

Synthetic ion channels are de novo chemical compounds that insert into lipid bilayers , form pores, and allow ions to flow from one side to the other. [ 1 ] They are man-made analogues of natural ion channels , and are thus also known as artificial ion channels . Compared to biological channels, they usually allow flu... | https://en.wikipedia.org/wiki/Synthetic_ion_channels |
In fluid dynamics , a synthetic jet flow—is a type of jet flow , which is made up of the surrounding fluid . [ 1 ] Synthetic jets are produced by periodic ejection and suction of fluid from an opening. This oscillatory motion may be driven by a piston or diaphragm inside a cavity among other ways.

Synthetic lethality is defined as a type of genetic interaction where the combination of two genetic events results in cell death or death of an organism. [ 1 ] Although the foregoing explanation is wider than this, it is common when referring to synthetic lethality to mean the situation arising by virtue of a combinat... | https://en.wikipedia.org/wiki/Synthetic_lethality |
An artificial membrane , or synthetic membrane , is a synthetically created membrane which is usually intended for separation purposes in laboratory or in industry. Synthetic membranes have been successfully used for small and large-scale industrial processes since the middle of the twentieth century.
