Lithium superoxide is extremely reactive because of the odd number of electrons present in the π* molecular orbital of the superoxide anion. [4] Matrix isolation techniques can produce pure samples of the compound, but they are only stable at 15-40 K. [3] At higher (but still cryogenic) temperatures, lithium superoxide can be produced by ...
Urinalysis, a portmanteau of the words urine and analysis, [1] is a panel of medical tests that includes physical (macroscopic) examination of the urine, chemical evaluation using urine test strips, and microscopic examination.
In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula O − 2. [1] The systematic name of the anion is dioxide(1−).The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O 2, which occurs widely in nature.

Naturally occurring lithium (3 Li) is composed of two stable isotopes, lithium-6 (6 Li) and lithium-7 (7 Li), with the latter being far more abundant on Earth. Both of the natural isotopes have an unexpectedly low nuclear binding energy per nucleon (5 332.3312(3) keV for 6 Li and 5 606.4401(6) keV for 7 Li) when compared with the adjacent lighter and heavier elements, helium (7 073.9156(4) keV ...
An Indiana pouch is a surgically-created urinary diversion used to create a way for the body to store and eliminate urine for patients who have had their urinary bladders removed as a result of bladder cancer, pelvic exenteration, bladder exstrophy or who are not continent due to a congenital, neurogenic bladder.
Burning lithium metal produces lithium oxide. Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen at temperatures above 100 °C: [3] 4Li + O 2 → 2 Li 2 O. Pure Li 2 O can be produced by the thermal decomposition of lithium peroxide, Li 2 O 2, at 450 °C [3] [2] 2 Li ...
Diabetes insipidus (DI) is a condition characterized by large amounts of dilute urine and increased thirst. [1] The amount of urine produced can be nearly 20 liters per day. [1] Reduction of fluid has little effect on the concentration of the urine. [1] Complications may include dehydration or seizures. [1]
