Quantum Chemical Methods to Elucidate the Mechanism of a Diastereoselective Insertion-Addition Reaction of a Chiral Titanium (IV)-Schiff Base-Benzyl Complex with Hydroxyketones

Ramos B., Castriciones E.V., University of the Philippines, PH

We present our preliminary results on the quantum chemical studies carried out to elucidate the diastereoselective insertion-addition reaction of a chiral titanium(IV)-Schiff base-benzyl complex (I) with hydroxyketones (II) to form the diastereoselective insertion product (III) [...]

Biphenyl-functionalized Ethane-silica Hybrid Materials with Ordered Hexagonal Mesoporous Structure

Virtudazo R., Magdaluyo Jr E., dela Cruz L., Castriciones E., Mendoza H., University of the Philippines, PH

A biphenyl-containing hybrid organic-inorganic mesoporous materials have been synthesized and characteized. The synthesis was done via surfactant-templated polymerization of 4,4’-bis(triethoxysilyl)biphenyl and 1,2-bis(triethoxysilyl)ethane under basic condition. The composition, structure and morphology of the mesoporous materials were [...]

A Fluid Dynamics Model for a Plasma Ion Acceleration System

Domingo F.S., Ramos H.J., University of the Philippines, PH

We present preliminary results of some simulations for a plasma ion acceleration system, which we plan to construct. This system tires to model the complex interactions between the multiple species of ions (about 5) used [...]
