Polystyrene sulfonate. Polystyrene sulfonates are a group of medications used to treat high blood potassium. [1] Effects generally take hours to days. [1] They are also used to remove potassium, calcium, and sodium from solutions in technical applications. Common side effects include loss of appetite, gastrointestinal upset, constipation, and ...
Photothermal therapy (PTT) refers to efforts to use electromagnetic radiation (most often in infrared wavelengths) for the treatment of various medical conditions, including cancer. This approach is an extension of photodynamic therapy, in which a photosensitizer is excited with specific band light. This activation brings the sensitizer to an ...
Poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is a polymer mixture of two ionomers. One component in this mixture is made up of polystyrene sulfonate which is a sulfonated polystyrene. Part of the sulfonyl groups are deprotonated and carry a negative charge.
Carbon nanotubes in photovoltaics. Organic photovoltaic devices (OPVs) are fabricated from thin films of organic semiconductors, such as polymers and small-molecule compounds, and are typically on the order of 100 nm thick. Because polymer based OPVs can be made using a coating process such as spin coating or inkjet printing, they are an ...
Lenthionine is an organic polysulfide found in shiitake mushrooms. In commerce, the term "polysulfide" usually refers to a class of polymers with alternating chains of several sulfur atoms and hydrocarbons. They have the formula R1SnR2. In this formula n indicates the number of sulfur atoms (or "rank"). Polysulfide polymers can be synthesized ...
The process begins with production of the radical cation of EDOT monomer, [C 2 H 4 O 2 C 4 H 2 S] +. This cation adds to a neutral EDOT followed by deprotonation. The idealized conversion using peroxydisulfate is shown: n C 2 H 4 O 2 C 4 H 2 S + n (OSO 3) 2 2− → [C 2 H 4 O 2 C 4 S] n + 2n HOSO 3 −
Solid-state battery. A solid-state battery is an electrical battery that uses a solid electrolyte for ionic conductions between the electrodes, instead of the liquid or gel polymer electrolytes found in conventional batteries. [1] Solid-state batteries theoretically offer much higher energy density than the typical lithium-ion or lithium ...
(Reuters) -The U.S. Food and Drug Administration on Wednesday approved Gilead Sciences' liver disease treatment, Livdelzi, which it gained through a $4.3 billion buyout of CymaBay Therapeutics ...
