Synthesis and Characterization of Branched and Hyperbranched Polyetherimides and Selective Chemistry on the Nanolithographically Defined Silicon(100) Surface
… as norbornadiene and metal precursors such as titanium tetrachloride were shown to chemoselectively react with the nanopatterned Si(100) surface. Additional studies of the hydrogen-terminated Si(100) exposed to ambient conditions showed that the UHV prepared hydrogen-terminated silicon surface …

Preparation of Copper-Based Oxygen Carrier Supported on Titanium Dioxide
… the supporting material is either directly from titanium(IV) oxide (anatase 99%) or that prepared from other titanium resources such as titanium tetrachloride and tetrabutyl titanate. Preliminary results showed the prepared oxygen carriers functioned properly in the multi-cycles of oxidization …

Techno-economic evaluation of demilitarized TiCl₄ recycling processes
… potential recycling solutions of demilitarized titanium tetrachloride (TiCl₄), which had been obtained by the preceding demilitarization of smoke mortars. The demilitarized TiCl₄ was quantified to be approximately 42 ton, distributed into smaller batches and processed over a period of six years. …

The synthesis of derivatives of naturally occurring naphthalenes
… of a C-8 brominated dioxolanyl naphthalene with titanium tetrachloride resulted in the formation of two angular naphtho[l,2-c]pyrans with the same relative stereochemistry of the pyran ring. An interesting bromine migration occurred after isomerisation had taken place. However, it is suggested …

Living cationic polymerization of styrene monomers
… ethylchloride (1-PEC) as an initiator and tin tetrachloride (SnCI4) as a catalyst in the presence of tetra-n-Butylammonium chloride (nBu4NCI). Effects of solvent polarity varied by mixing dichloromethane (DCM) and less polar cyclohexane (C.hex), temperature, initial concentrations of SnC14, …

Ionic liquid electrochemical processing of reactive metals
… with increased anode-cathode spacing. Titanium tetrachloride was found to be soluble in [P14,6,6,6]Cl and increases the conductivity of the solution. Attempts to reduce the Ti(IV) included corrosion of titanium metal, corrosion of magnesium metal powder and cathodic polarization. …
