Delafossite is a copper iron oxide mineral with formula CuFeO 2 or Cu 1+ Fe 3+ O 2.It is a member of the delafossite mineral group, which has the general formula ABO 2, a group characterized by sheets of linearly coordinated A cations stacked between edge-shared octahedral layers (BO 6). [5]
An accessory bile duct is a conduit that transports bile and is considered to be supernumerary or auxiliary to the biliary tree. [ 1 ] It may be described by its location relative to the gallbladder as supravesicular [ 2 ] [ 3 ] (superior to the gallbladder body) or subvesicular [ 4 ] [ 5 ] (inferior to the gallbladder body).
Male accessory gland infection (MAGI) is a condition with signs of inflammation involving one or more sites in the male genital tract. Diagnosis is made according to parameters defined by the World Health Organization , and it is particularly made in relation to infectious or inflammatory causes of male infertility .
The male accessory glands are the ampullary gland, seminal vesicle, prostate, bulbourethral gland, and urethral gland. [5]The products of these glands serve to nourish and activate the spermatozoa, to clear the urethral tract prior to ejaculation, serve as the vehicle of transport of the spermatozoa in the female tract, and to plug the female tract after placement of spermatozoa to help ensure ...
As a significant product of copper mining, copper(II) oxide is the starting point for the production of many other copper salts. For example, many wood preservatives are produced from copper oxide. [3] Cupric oxide is used as a pigment in ceramics to produce blue, red, and green, and sometimes gray, pink, or black glazes. [3]
Iron(III) oxide is a product of the oxidation of iron. It can be prepared in the laboratory by electrolyzing a solution of sodium bicarbonate, an inert electrolyte, with an iron anode: 4 Fe + 3 O 2 + 2 H 2 O → 4 FeO(OH) The resulting hydrated iron(III) oxide, written here as FeO(OH), dehydrates around 200 °C. [18] [19] 2 FeO(OH) → Fe 2 O 3 ...
Crystal structure of iron(II) oxalate dihydrate, showing iron (gray), oxygen (red), carbon (black), and hydrogen (white) atoms. Blood-red positive thiocyanate test for iron(III) Iron(III) complexes are quite similar to those of chromium(III) with the exception of iron(III)'s preference for O-donor instead of N-donor ligands. The latter tend to ...
Copper oxide is any of several binary compounds composed of the elements copper and oxygen. Two oxides are well known, Cu 2 O and CuO, corresponding to the minerals cuprite and tenorite, respectively. Paramelaconite (Cu 4 O 3) is less well characterized. [1] Copper oxide may refer to: Copper(I) oxide (cuprous oxide, Cu 2 O) Copper(II) oxide ...
