Heat Engines

3.6K
A heat engine is a device used to extract heat from a source and then convert it into mechanical work used for various applications. For example, a steam engine on an old-style train can produce the work needed for driving the train.
Whenever we consider heat engines (and associated devices such as refrigerators and heat pumps), we do not use the standard sign convention for heat and work. For convenience, we assume that the symbols Qh, Qc, and W represent only the amounts of heat transferred...

Internal Combustion Engine01:20

Internal Combustion Engine

2.7K
The internal combustion engine is a heat engine that uses the byproducts of combustion as the working fluid instead of using a heat transfer medium to transfer heat. The combustion is done in a way that produces high-pressure combustion products that can be expanded through a turbine or piston to create work. Internal combustion engines can again be categorized into three kinds: (1) spark ignition gasoline engines, most commonly used in automobiles, (2) compression ignition diesel engines that...

Active versus Passive Immunity01:31

Active versus Passive Immunity

10.8K
Immunity, along with the ability to limit pathogen growth to prevent significant body tissue damage, can be gained either by (1) actively developing an immune response within the individual after exposure to a pathogen or after getting vaccinated or (2) passively transferring immune components from an immune individual to one who is nonimmune. Both these forms of immunity can be found naturally and in medical practices.
Active Immunity
Active immunity refers to the resistance one develops...

Purpose of the Study:

  • To review the use of engineered biomaterials for modulating immune responses.
  • To highlight advancements in leveraging biomaterials for immunological tolerance.
  • To explore biomaterials as carriers, depots, scaffolds, and immunomodulatory agents.

Main Methods:

  • Review of current literature on biomaterials in immunology.
  • Analysis of engineered materials (polymeric, lipid, inorganic) for immune regulation.
  • Discussion of biomaterials' roles as carriers, depots, scaffolds, and active agents.

Main Results:

  • Engineered materials offer precise control over immune interactions.
  • Biomaterials can selectively regulate immune function during disease.
  • Materials can be designed with intrinsic immunomodulatory properties.

Conclusions:

  • Biomaterials represent a promising strategy for promoting immunological tolerance.
