Effect of Amino Functionality on the Uptake of Cationic Dye by Titanium-Based Metal Organic Frameworks
Titanium-based metalorganic frameworks (MOFs), named MIL-125 and NH2-MIL-125, have been successfully synthesized by the hydrothermal method. They were specially designed for the application of methylene blue (MB) removal from aqueous solution. The maximum adsorption capacityof MB was found to be 321.39 mg/g and 405.61 mg/g. The amount of dye
that has been adsorbed 99.9% was 300 ppm within 20 ...

Titanium Complex Bearing 8-Anilino-1-naphthalenesulfonate Ligand: Synthesis and Catalytic Behavior Toward Ethylene (co-)Polymerization
A novel titanium complex bearing 8-anilino-1-naphthalenesulfonic acid was synthesized. The effects of cocatalyst and reaction conditions on ethylene polymerization were studied. The synthesized titanium complex exhibited high polymerization activity in the presence of MAO cocatalyst. The synthesized titanium complex/MAO catalyst system showed a uniform active site and was very stable at high pol...

Concentration-driven phase control for low temperature synthesis of phase-pure anatase and rutile titanium oxide
It is highly desirable to develop controlled synthetic methods at low temperature (<100 °C) for defined phases of titanium oxide nanoparticle. We present here a simple low temperature approach which is based on the peroxide route. This approach allows the preparation of phase-pure rutile and anatase without the use of any additives or surfactants or external acids. The formation of crystalline...

A Bioorthogonal Approach for the Preparation of a Titanium-Binding Insulin-like Growth-Factor-1 Derivative by using Tyrosinase
Enhanced cell growth occurs on a titanium surface modified with insulin-like growth-factor-1 prepared by a bioorthogonal approach combining protein engineering and enzyme modification, as shown by Y. Ito and co-workers in their Communication (10.1002/anie.201603155). The picture shows a peptide sequence (center), which is inspired by an underwater adhesion protein (represented as a strong man) s...
