The effects of critical factors such as Henry's Law constant, atmospheric OH rate constant, initial concentration, H2O2, FeSO4 and tert-butanol on the sonochemical degradation of fumaric acid have been investigated. The pseudo first-order rate constant for the sonochemical degradation of 1mM fumaric
Several microbes were isolated from the contaminated fuel-oil in Taiwan and the microbial corrosion of aluminum alloy A356-T6 was tested by MIL-STD-810E test method. Penicillium sp. AM-F5 and Cladosporium resinac ATCC 22712 had significant adsorption and pitting on the surface of aluminum alloy,
Thirteen buffers were investigated for their effect on the binding of adamantanol to β-cyclodextrin and hydroxypropyl-β-cyclodextrin. Stability constants for the β-cyclodextrin complex ranged from 14,800 to 46,000 M-1, and the binding enthalpies were between -23.2 and -10.4 kJ/mole.
Porphyrins are an extremely valuable class of molecules engaged in a variety of roles spanning from biology to optoelectronics. Manipulation of the chemical and physical properties of the inner cavity of porphyrins has been recognized as crucial for the exploitation of these systems in organic
A series of lanthanide fumarates [Sm2(fum)3(H2fum)(H2O)2] (1, H2fum = fumaric acid), [Ln2(fum)3-(H2O)4]·3H2O {Ln = Tb (2a), Dy (2b)} and [Ln2(fum)3(H2O)4] {Ln = Y (3a), Ho (3b), Er (3c), Tm (3d)} were prepared by the hydrothermal method and their structures were classified into three types. The 3-D
A new host design for an inclusion compound with a preference for large planar aromatic guest molecules has been proposed. Our host design includes a rectangular cavity made using a long and a short building block based on the concept of supramolecular chemistry. The long building block facilitates
