Abstract Applications of organic–inorganic formamidinium (FA) lead triiodide (FAPbI 3 ) perovskites in high-efficiency solar cells often suffer from spontaneous ?-to-? phase transitions. However, current efforts to inhibit this phenomenon based on simple cation and anion alloying strategies continue unintended consequences, such as unfavorable shifts the bandgap energy unwanted separation durin...

Native solium and potassium adenosine triphosphatase from guinea pig kidney accepted a phosphate group from radioactive inorganic phosphate to form an acyl phosphate bond at the active site in the presence or absence of sodium ion. Magnesium ion was always required. In the presence of sodium ion and absence of adenosine triphosphate, there was no phosphorylation by inorganic phosphate. Addition...

The effects of heterogeneous reactions between river-borne particles and the carbonate system were studied in plumes Mississippi Brazos rivers. Measurements within these revealed significant removal dissolved inorganic carbon (DIC) total alkalinity (TA). After accounting for all known DIC TA sinks sources, (i.e., CaCO3 precipitation cation exchange adsorbed ions) found to be responsible a fract...

Selenium (Se) is an essential element for animals, including fish. Due to changes in feed composition for Atlantic salmon (Salmo salar), it may be necessary to supplement feeds with Se. In the present work, the transfer of Se and Se species from feed to muscle of Atlantic salmon fed Se supplemented diets was studied. Salmon were fed basal fish feed (0.35 mg Se/kg and 0.89 mg Se/kg feed), or fee...
