The substitution of oxygen by fluorine in borate group offers a brand new materials platform from which intriguing structure and functionality may arise. Here, we report a new fluorooxoborate, BaB2O3F2, synthesized by introducing the F atoms into the BaO-B2O3 system. BaB2O3F2 exhibits a unique oxyfluoride layer (_"∞" ^"2" )"[B2O3F]-" and a deep-ultraviolet cutoff edge below 180 nm. The effect of the introduction of F atoms on the structure and optical property has been investigated which should be useful to further expand the borate chemistry and materials.

Tears play a vital role in vision. A thin layer of tears is always present to cover the surface of the eye for optimal comfort and vision. There are several layers to the tear film, and th...
X-RAY examination of LOWER GASTROINTESTINAL TRACT. Imaging is done while a BARIUM COMPOUND (e.g., BARIUM SULFATE) fills the large intestine via the rectum as a CONTRAST MATERIAL.
Unstable isotopes of barium that decay or disintegrate emitting radiation. Ba atoms with atomic weights 126-129, 131, 133, and 139-143 are radioactive barium isotopes.
Inorganic compounds that contain barium as an integral part of the molecule.
The external, nonvascular layer of the skin. It is made up, from within outward, of five layers of EPITHELIUM: (1) basal layer (stratum basale epidermidis); (2) spinous layer (stratum spinosum epidermidis); (3) granular layer (stratum granulosum epidermidis); (4) clear layer (stratum lucidum epidermidis); and (5) horny layer (stratum corneum epidermidis).
Synthetic material used for the treatment of burns and other conditions involving large-scale loss of skin. It often consists of an outer (epidermal) layer of silicone and an inner (dermal) layer of collagen and chondroitin 6-sulfate. The dermal layer elicits new growth and vascular invasion and the outer layer is later removed and replaced by a graft.
