We present an Auger electron spectroscopy (AES) study of the adsorption of nitric oxide (NO) on a dean Si(100)2 × 1 surface at 300 and 550 K. Accurate measurements reveal wall resolved fine structure at Auger Si L2.3 w transitions at 62 and 83 eV. These peaks can be attributed to Si-O and Si-N bonds. Furthermore, it is argued that the broadening in the SiLi2,~W Auger transition at 83 eV at 300 ...

A significant improvement in the dehydrogenation kinetics of the (LiNH(2) + LiH) system was obtained upon doping with elemental Si. Whilst, complete dehydrogenation of the (LiNH(2) + LiH) system requires more than 2 h, the time required for full dehydrogenation was reduced to less than 30 min by doping with elemental Si. It is observed that Si thermodynamically destabilises the system through t...

In this work, we have calculated ab initio the structural and electronic properties of both the Cand Si-terminated SiC (100) surfaces in the c(2!2) and (2!1) reconstruction patterns, respectively. Based on our results, we found that the Si-terminated surfaces is dominated by weak bonded Si-dimers, which is stabilized only at Si-rich conditions, leading to a (3!2) or more complex reconstruction ...

The five-coordinate carbene complexes [Ru{κP,P,Si-Si(Me)(C6H4-2-PiPr2)2}Cl(═CHR)] (2, R = Ph; 3, R = SiMe3), analogues of the Grubbs catalyst, were prepared from the dimer [Ru(μ-Cl){κP,P,Si-Si(Me)(C6H4-2-PiPr2)2}]2 (1) and the corresponding diazoalkane N2CHR. The particular structural features that result from the presence of a strongly trans directing silyl group at the pincer ligand of these ...

Delayed cytoprotection (preconditioning) occurs 24 h after sublethal simulated ischaemia and reperfusion (SI/R) in neonatal rat ventricular cardiomyocytes. SI/R was used to investigate the role of activation of mitogen-activated protein kinases (MAPKs), stress-activated protein kinases (SAPKs) and phosphoinositide 3-kinase-dependent protein kinase B (PKB)/Akt in cytoprotection. SI resulted in t...

In the course of our studies of silicon-containing anti-cancer compounds, the title compound, C(18)H(19)NO(3)Si, was synthesized. The mol-ecular geometry including bond distances and angles involving the Si atoms are typical. Torsion angles associated with the isoindoline ring and the silyl group [C-N-C(methyl-ene)-Si = 90.5 (2) and -93.1 (2)°] indicate that there is no inter-action between the...

We report on the synthesis of novel coinage metal NHC (N-heterocyclic carbene) compounds of the germanium-rich metalloid clusters [Ge9R3] and [Ge9R2] with R = Si(Pr)3 and RI = Si(TMS)3. NHCCu{η-Ge9R3} with R = Si(Pr)3 (1) represents a less bulky silyl group-substituted derivative of the known analogous compounds with R = Si(Bu)3 or Si(TMS)3. The coordination of the [NHCDippCu]+ moiety to the cl...
