Heat Engines01:10

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...

Reaction Yield02:22

Reaction Yield

59.7K
The theoretical yield of a reaction is the amount of product estimated to form based on the stoichiometry of the balanced chemical equation. The theoretical yield assumes the complete conversion of the limiting reactant into the desired product. The amount of product that is obtained by performing the reaction is called the actual yield, and it may be less than or (very rarely) equal to the theoretical yield.

Self-Discrepancy Theory02:45

Self-Discrepancy Theory

18.9K
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Formal Charges02:42

Formal Charges

40.3K
In some cases, there are seemingly more than one valid Lewis structures for molecules and polyatomic ions. The concept of formal charges can be used to help predict the most appropriate Lewis structure when more than one reasonable structure exists.

Background:

  • Lectins are diverse sugar-binding proteins found across all life forms.
  • Over 50 lectin scaffolds are known, with more expected to be discovered or evolve.

Purpose of the Study:

  • To review methods for engineering lectin specificity and stability.
  • To explore approaches for conferring sugar-binding properties on non-lectin protein scaffolds.

Main Methods:

  • Literature review of existing lectin engineering techniques.
  • Discussion of potential strategies for de novo design of sugar-binding proteins.

Main Results:

  • Current methods allow modification of known lectin scaffolds.
  • The potential exists to engineer non-lectin proteins to bind sugars.

Conclusions:

  • Protein engineering offers avenues to create novel lectins.
  • Future research may focus on experimentally generating new lectin domains and conferring sugar-binding functions on diverse protein scaffolds.
