Metaphosphate acids cannot be thoroughly studied in aqueous media because their acidity is leveled by the solvent, and the resulting metaphosphates are susceptible to acid-catalyzed hydrolysis. Exploration of metaphosphate acid chemistry has now been made possible with the development of a general s

The structures and intrinsic gas-phase acidities (GA) of some dodecaborane acids, the derivatives of YB12H11H (Y = PF3, NH3, NF3, NMe3), B12H12H2, and B12H12H(-) (HA, H2A, and HA(-), respectively) have been computationally explored with DFT B3LYP method at the 6-311+G** level of theory as new possib

Superacids, defined as acids with a Hammett acidity function H0 ≤ -12, are useful materials, but a need exists for new, designable solid state systems. Here, we report superacidity in a sulfated metal-organic framework (MOF) obtained by treating the microcrystalline form of MOF-808 [MOF-808-P: Zr6
… Poor also in following cases: red cell sedimentation accelerated cases, superacidity cases by gastric base secretion and, in reverse, hypoacidity cases gastric irritated secretion, ptosis and rinder horn forms of stomach, and poor tonicity stomach cases.2) About absorption quantity of staple food, the same tendency was found as appetite.3) About sorts of fat and oil, most of men and women prefer fat, especially butter, Taste for oil is found in patients over 20 years old. …
