Polymers02:34

Polymers

41.4K
The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Chemistry of the Cell

48.4K
The cell is chemically composed of water, organic molecules and inorganic ions.
Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity...

Chemistry of Carbohydrates

91.2K
Carbohydrates are an essential part of the diet in humans and animals. Grains, fruits, and vegetables are natural sources of carbohydrates that provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. The stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule represents carbohydrates. In other words, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. This...

Introduction to Statistical Process Control

673
Statistical Process Control (SPC) is a method used to monitor and control quality within processes, particularly in manufacturing and service delivery, by employing statistical methods. SPC aims to distinguish between natural (common cause) variation and variation due to specific changes or events (special cause), allowing for timely improvements and sustained quality. The control chart, a pivotal tool in SPC, visually displays data over time alongside a central line of upper and lower control...

Local Anesthetics: Chemistry and Structure-Activity Relationship

6.8K
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...

Cholinergic Antagonists: Chemistry and Structure-Activity Relationship01:29

Cholinergic Antagonists: Chemistry and Structure-Activity Relationship

2.8K
Cholinergic antagonists bind to cholinergic receptors and limit the effects of acetylcholine and other cholinergic agonists. Based on the specific cholinergic receptor affinity, these antagonists are classified as muscarinic or nicotinic. Anticholinergics interrupt parasympathetic innervations while sympathetic innervations remain uninterrupted. Muscarinic antagonists are also called 'muscarinic antagonists', 'antimuscarinics', or 'parasympatholytics'. Nicotinic...

Area of Science:

  • Polymer Chemistry
  • Catalysis
  • Nanotechnology

Background:

  • Controlled catalytic processes are crucial for chemical synthesis.
  • Developing smart materials with tunable properties is an active research area.
  • Hyperbranched polymers offer unique structural characteristics for material design.

Purpose of the Study:

  • To report a novel self-switchable polymer reactor for controlled catalytic chemistry.
  • To investigate the tunable catalytic activity of a polymer reactor based on temperature-responsive domains.

Main Methods:

  • Fabrication of a polymer reactor using silver nanoparticles and a polymer carrier (hyperbranched polyethylenimine and hydroxyethyl acrylate).
  • Investigation of the polymer reactor's catalytic activity at different temperatures.
  • Analysis of the role of hydrophilic and hydrophobic groups in the switchable domains.

Main Results:

  • The polymer reactor exhibited strong catalytic reactivity below a specific transfer temperature due to hydrophilic domains.
  • Catalytic activity significantly decreased at higher temperatures due to increased hydrophobicity of the domains.
  • The system demonstrated controllable and tunable catalytic activity.

Conclusions:

  • A self-switchable polymer reactor with a hyperbranched structure was successfully developed.
  • The reactor's catalytic activity can be controlled by temperature-induced changes in domain hydrophilicity/hydrophobicity.
