Electrolyte salts with Mg2+ and Al3+ Lewis acidic cations demonstrate polymerization of 1,3-dioxolane. The speed and extent of the reaction depends on coordination of the anion with the Mg2+ cation catalyst. Weakly coordinating anions such as TFSI- aid faster polymerization while strongly coordinating anions such as ClO4- hinder the polymerization.

The stereoselective ring-opening polymerization (ROP) of O-carboxyanhydrides (OCAs) remains a major challenge due to the easy epimerization of monomers. In this work, using a zinc alkoxide initiator, ...
The lithium sulfur battery is regarded as a potential next-generation high energy battery system. However, polysulfides dissolve and shuttle through the electrolytes, causing rapid capacity decay, ser...
High-voltage polymer electrolytes play important roles in achieving high energy density polymer electrolyte-based batteries, but the pace of progress moves slowly since oxidation-resistant polymer ele...
A new capillary electrophoresis (CE) method with ultraviolet-visible (UV/Vis) detection was developed in this study, to investigate manganese dissolution in lithium ion battery (LIB) electrolytes. The...
Advances in lithium battery technologies necessitate improved energy densities, long cycle lives, fast charging, safe operation, and environment-friendly components. In this study, we investigated lit...
Polymerization shrinkage remains one of the primary disadvantages of composite resin restorative materials (tooth-colored fillings). To minimize the effects of polymerization shrinkage in ...
The aim of this study is to evaluate the quality, acceptance, tolerability and adverse effects of colonoscopy preparations with the different available preparation guidelines.
Adhesive restorative materials are routinely used in operative dentistry to improve tooth tissues with minimal preparation, achieve more esthetic and long term restorations. Despite these ...
Bowel preparation is a crucial step prior to colonoscopy to help with the optimal assessment of the colonic mucosa. Inadequate bowel preparation increases the length of the procedure, and ...
Aim of the present study is to compare the response to furosemide stress test in term of diuresis and electrolytes and of the renal index in mechanically ventilated patients at admission a...
A series of tests designed to assess neuropsychological function. The battery is used to diagnose specific cerebral dysfunction and also to determine lateralization.
Substances that dissociate into two or more ions, to some extent, in water. Solutions of electrolytes thus conduct an electric current and can be decomposed by it (ELECTROLYSIS). (Grant & Hackh's Chemical Dictionary, 5th ed)
A thiazide diuretic often considered the prototypical member of this class. It reduces the reabsorption of electrolytes from the renal tubules. This results in increased excretion of water and electrolytes, including sodium, potassium, chloride, and magnesium. It is used in the treatment of several disorders including edema, hypertension, diabetes insipidus, and hypoparathyroidism.
An ENTEROTOXIN from VIBRIO CHOLERAE. It consists of two major protomers, the heavy (H) or A subunit and the B protomer which consists of 5 light (L) or B subunits. The catalytic A subunit is proteolytically cleaved into fragments A1 and A2. The A1 fragment is a MONO(ADP-RIBOSE) TRANSFERASE. The B protomer binds cholera toxin to intestinal epithelial cells, and facilitates the uptake of the A1 fragment. The A1 catalyzed transfer of ADP-RIBOSE to the alpha subunits of heterotrimeric G PROTEINS activates the production of CYCLIC AMP. Increased levels of cyclic AMP are thought to modulate release of fluid and electrolytes from intestinal crypt cells.
Cements that act through infiltration and polymerization within the dentinal matrix and are used for dental restoration. They can be adhesive resins themselves, adhesion-promoting monomers, or polymerization initiators that act in concert with other agents to form a dentin-bonding system.
