Theoretical Study of the Bis-Silylation Reaction of Ethylene Catalyzed by Titanium Dichloride Abstract Titanium dichloride was investigated as a potential catalyst for the bis-silylation reaction of ethylene with hexachlorodisilane. Ab initio electronic structure calculations at the restricted Hartree−Fock (RHF), density functional (DFT), second-order perturbation (MP2), and couple cluster (CCSD) levels of theory were used to find optimized structures, saddle points, and minimum-energy paths that connect them. The er action was found to have a net zero barrier at the DFT, MP2, and CCSD levels of theory. Dynamic correlation is found to be important for this reaction.

Lithium Hydride Powered PEM Fuel Cells for Long-Duration Small Mobile Robotic Missions
Lithium Hydride Powered PEM Fuel Cells for Long-Duration Small Mobile Robotic Missions Jekanthan Thangavelautham, Daniel Strawser, Mei Yi Cheung Steven Dubowsky Abstract— This paper reports on a study to develop power supplies for small mobile robots performing long duration missions. It investigates the use of fuel cells to achieve this objective, and in particular Proton Exchange Membrane (PEM) fuel cells. It is shown through a representative case study that, in theory, fuel cell based power supplies will provide much longer range than the best current rechargeable battery technology. It also briefly discusses an important limitation that prevents fuel cells from achieving their ideal performance, namely a practical method to store their fuel (hydrogen) in a form that is compatible with small mobile field robots. A very efficient Fig. 1. Example of small robots (Left) A ball shaped hopping robot concept fuel storage concept based on water activated lithium hydride for exploration of extreme terrains and caves developed for NASA. (Right) (LiH) is proposed that releases hydrogen on demand. This iRobot 110 Firstlook used for observation, security and search and rescue. concept is very attractive because water vapor from the air is passively extracted or waste water from the fuel cell is recycled and transferred to the lithium hydride where the hydrogen is the near future. Hence, new means for powering field robots “stripped” from water and is returned to the fuel cell to form more water. This results in higher hydrogen storage efficiencies need to be considered. than conventional storage methods. Experimental results are This paper explores the use of fuel cells, and in particular presented that demonstrate the effectiveness of the approach. -
A Novel Series of Titanocene Dichloride Derivatives: Synthesis, Characterization and Assessment of Their
A novel series of titanocene dichloride derivatives: synthesis, characterization and assessment of their cytotoxic properties by Gregory David Potter A thesis submitted to the Department of Chemistry in conformity with the requirements for the degree of Doctor of Philosophy Queen’s University Kingston, Ontario, Canada May, 2008 Copyright © Gregory David Potter, 2008 Abstract Although cis-PtCl2(NH3)2 (cisplatin) has been widely used as a chemotherapeutic agent, its use can be accompanied by toxic side effects and the development of drug resistance. Consequently, much research has been focused on the discovery of novel transition metal compounds which elicit elevated cytotoxicities coupled with reduced toxic side effects and non-cross resistance. Recently, research in this lab has focused on preparing derivatives of titanocene dichloride (TDC), a highly active chemotherapeutic agent, with pendant alkylammonium groups on one or both rings. Earlier results have demonstrated that derivatives containing either cyclic or chiral alkylammonium groups had increased cytotoxic activities. This research therefore investigated a new series of TDC complexes focusing specifically on derivatives bearing cyclic and chiral alkylammonium groups. A library of ten cyclic derivatives and six chiral derivatives were synthesized and fully characterized. These derivatives have undergone in vitro testing as anti-tumour agents using human lung, ovarian, and cervical carcinoma cell lines (A549, H209, H69, H69/CP, A2780, A2780/CP and HeLa). These standard cell lines represent solid tumour types for which new drugs are urgently needed. The potencies of all of the Ti (IV) derivatives varied greatly (range from 10.8 μM - >1000 μM), although some trends were observed. In general, the dicationic analogues exhibited greater potency than the corresponding monocationic derivatives. -
