Precipitate Formation and Particle Size Control

6.1K
In precipitation gravimetry, the precipitating agent should react specifically or selectively with the analyte. While a specific reagent reacts with the analyte alone, a selective reagent can react with a limited number of chemical species.
The obtained precipitate should be either a pure substance of known composition or easily converted to one by a simple process, such as ignition or drying. In addition, the precipitate should be insoluble and easily filterable. In general, filterability...

Restoring Memory Formation in a Memory-Deficient Mouse Model through Allosteric Modulation

122
Begin with a genetically modified (GM) mouse with disrupted downstream signaling of mGluR5, a neurotransmitter receptor.In the hippocampus of a regular mouse, mGluR5 regulates endocytosis of fast-acting excitatory receptors from existing synapses, weakening them.Internalized receptors are recycled to newly formed synapses, strengthening them for memory formation.In the GM mouse, impaired mGluR5 signaling reduces receptor redistribution, disrupting new memory formation.Expose the mouse to a...

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures. 
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated. 
A mixture is composed of two or...
