A 3D new metal-organic framework (MOF) [Cu4Cl(TIPE)3]·3Cl (1) has been synthesized and characterized. Compound 1 exhibits good chemical stability in aqueous solution with the pH ranging from 1 to 11. Interestingly, compound 1 shows high catalytic activities for the degradation of dyes (RhB, MB and MO) under LED and natural light irradiation. The Ea of 1 for RhB, MB and MO degradation is obtaine...
Inorganic membrane science and technology is an attractive field of membrane separation technology, which has been dominated by polymer membranes. Recently, the inorganic membrane has been undergoing rapid development and innovation. Inorganic membranes have the advantage of resisting harsh chemical cleaning, high temperature and wear resistance, high chemical stability, long lifetime, and auto...
Rare-earth tantalates, with high density and monoclinic structure, and niobates with monoclinic structure have been paid great attention as potential optical materials. In the last decade, we focused on the crystal growth technology of rare-earth tantalates and niobates and studied their luminescence and physical properties. A series of rare-earth tantalates and niobates crystals have been grow...
The physicochemical properties of cationic dioxa (1), azaoxa (2), and diaza (3) [6]helicenes demonstrate a much higher chemical stability of the diaza adduct 3 (pKR+ =20.4, Ered1/2 =-0.72 V) compared to its azaoxa 2 (pKR+ =15.2, Ered1/2 =-0.45 V) and dioxa 1 (pKR+ =8.8, Ered1/2 =-0.12 V) analogues. The fluorescence of these cationic chromophores is established, and ranges from the orange to the...
Pickering emulsion, which is an emulsion stabilized by solid particles, offers a wide range of potential applications because it generally provides a more stable system than surfactant-stabilized emulsion. Among various solid stabilizers, nanocellulose may open up new opportunities for future Pickering emulsions owing to its unique nanosizes, amphiphilicity, and other favorable properties (e.g....
Over the last decade, nanopores have emerged as a new and interesting tool for the study of biological macromolecules like proteins and DNA. While biological pores, especially alpha-haemolysin, have been promising for the detection of DNA, their poor chemical stability limits their use. For this reason, researchers are trying to mimic their behaviour using more stable, solid-state nanopores. Th...
T7 early mRNA produced by a gene 1 amber mutant phage, T7 am27, is chemically stable interms of acid insolubility and T7 DNA hybridizability. However, the messenger activity of individual T7 early mRNA species, transcripts of gene 1, gene 0.7, and gene 1.3, decay with a half-life of about 6.5 min at 30 C. An extensive secondary structure is present in all T7 early mRNA species and is probably r...
Porous gold films have attracted increasing interest over the last ten years due to the unique properties of high specific surface area and electrical conductivity combined with chemical stability and ability to alter the surface chemistry. Several methods have been developed to synthesize porous gold films such as de-alloying, templating, electrochemical, and self-assembling. These porous gold...
The objective of this work was to evaluate the solution stability of the EC1 domain of E-cadherin under various conditions. The EC1 domain was incubated at various temperatures (4, 37, and 70 degrees C) and pH values (3.0, 7.0, and 9.0). At pH 9.0 and 37 or 70 degrees C, a significant loss of EC1 was observed due to precipitation and a hydrolysis reaction. The degradation was suppressed upon ad...
IgG subclass-specific differences in biological function and in vitro stability are often referred to variations in the conformational flexibility, while this flexibility has rarely been characterized. Here, small-angle X-ray scattering data from IgG1, IgG2 and IgG4 antibodies, which were designed with identical variable regions, were thoroughly analysed by the ensemble optimization method. The...
