Pellicle (mycology)
Pellicle may refer to: *Pellicle (biology), a thin layer supporting the cell membrane in various protozoa *Pellicle mirror, a thin plastic membrane which may be used as a beam splitter or protective cover in optical systems * Pellicle (dental), the thin layer of salivary glycoproteins deposited on the teeth of many species through normal biologic processes *Pellicle, the protective cover which can be applied to a photomask used in semiconductor device fabrication. The pellicle protects the photomask from damage and dirt *Pellicle (cooking) A pellicle is a skin or coating of proteins or cellulose on the surface of meat (e.g. smoked salmon) or fermented beverages (e.g. Kombucha). Pellicles of protein that form prior to smoking meat (including fish and poultry) allow smoke to better ..., a growth on the surface of fermenting liquids (e.g. SCOBY), or skin of proteins on the surface of meat, fish or poultry, which allow smoke to better adhere the surface of the meat during the smok ...

Pellicle (biology)
Protozoa (: protozoan or protozoon; alternative plural: protozoans) are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris. Historically, protozoans were regarded as "one-celled animals". When first introduced by Georg Goldfuss, in 1818, the taxon Protozoa was erected as a class within the Animalia, with the word 'protozoa' meaning "first animals", because they often possess animal-like behaviours, such as motility and predation, and lack a cell wall, as found in plants and many algae. This classification remained widespread in the 19th and early 20th century, and even became elevated to a variety of higher ranks, including phylum, subkingdom, kingdom, and then sometimes included within the paraphyletic Protoctista or Protista. By the 1970s, it became usual to require that all taxa be monophyletic (derived from a common ancestor that would also be regarded as protozo ...

Pellicle Mirror
A pellicle mirror is an ultra-thin, ultra-lightweight Transparency (optics), semi-transparent mirror employed in the light path of an optical instrument, splitting the light beam into two separate beams, both of reduced light intensity. Splitting the beam allows its use for multiple purposes simultaneously. The thinness of the mirror practically eliminates beam or image doubling due to a non-coincident weak second reflection from the nominally non-reflecting surface, a problem with mirror-type beam splitters. The name ''pellicle'' is a diminutive of ''pellis'', a skin or film. In photography In photography, the pellicle mirror has been employed in SLR camera, single-lens reflex (SLR) cameras, at first to enable through-the-lens exposure measurement and possibly to reduce camera shake, but later most successfully to enable fast series photography, which otherwise would be slowed down by the movement of the reflex mirror, while maintaining constant finder vision. The first use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Photomask
A photomask (also simply called a mask) is an opaque plate with transparent areas that allow light to shine through in a defined pattern. Photomasks are commonly used in photolithography for the production of integrated circuits (ICs or "chips") to produce a pattern on a thin wafer of material (usually silicon). In semiconductor manufacturing, a mask is sometimes called a reticle. In photolithography, several masks are used in turn, each one reproducing a layer of the completed design, and together known as a mask set. A curvilinear photomask has patterns with curves, which is a departure from conventional photomasks which only have patterns that are completely vertical or horizontal, known as manhattan geometry. These photomasks require special equipment to manufacture. History For IC production in the 1960s and early 1970s, an opaque rubylith film laminated onto a transparent mylar sheet was used. The design of one layer was cut into the rubylith, initially by hand on an i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pellicle (cooking)
A pellicle is a skin or coating of proteins or cellulose on the surface of meat (e.g. smoked salmon) or fermented beverages (e.g. Kombucha). Pellicles of protein that form prior to smoking meat (including fish and poultry) allow smoke to better adhere to the surface of the meat during the smoking process. Useful in all smoking applications and with any kind of animal protein, it is best used with fish where the flesh of a fish such as salmon forms a pellicle that will attract more smoke to adhere to it than would be the case if it had not been used. Pellicles of cellulose that form in fermenting beverages, such as SCOBYs, are biofilms that are produced as fermentation takes place. Pellicle formation on meat and seafood Before cured foods are cold smoked, they can be allowed to air-dry to form a tacky outer layer, known as a pellicle. The pellicle plays a role in producing better smoked products as it acts as a protective barrier for the food and also plays a role in enhanci ...
