    Description: The reaction of GeBr with LiSi(SiMe(3))(3) leads to the metalloid cluster compound [(THF)(2)Li](3)Ge(14)[Si(SiMe(3))(3)](5) (1). After the introduction of a first cluster of this type, in which 14 germanium atoms form an empty polyhedron, [(THF)(2)Li](3)Ge(14)[Ge(SiMe(3))(3)](5) (2), we present here further investigations on 1 to obtain preliminary insight into its chemical and bonding properties. The molecular structure of 1 is determined via X-ray crystal structure solution using synchrotron radiation. The electronic structure of the Ge(14) polyhedron is further examined by quantum chemical calculations, which indicate that three singlet biradicaloid entities formally combine to yield the singlet hexaradicaloid character of 1. Moreover, the initial reactions of 1 after elimination of the [Li(THF)(2)](+) groups by chelating ligands (e.g., TMEDA or 12-crown-4) are presented. Collision induced dissociation experiments in the gas phase, employing FT-ICR mass spectrometry, lead to the elimination of the singlet biradicaloid Ge(5)H(2)[Si(SiMe(3))(3)](2) cluster. The unique multiradicaloid bonding character of the metalloid cluster 1 might be used as a model for reactions and properties in the field of surface science and nanotechnology.

    Description: The use of drone in aerial photography in Martha Stewart's "Amazing Aerial Photos of My Farm" and Vogue's "Here's Looking at You" is examined. These collections fantasize image worlds in which women of privilege invite the drone's penetrating eye into their private spaces. However, these are in contrast to the conditions of those who live in regions under the flight path of militarized drones.

    Description: Abstract:In recent years, photographs featuring drones at home have appeared in women's mass-media publications such as The Martha Blog and Vogue. This essay explores how such images introduce the War on Terror to the US domestic sphere through fantasies of imperialist nostalgia.

    Description: The reaction of a metastable SiCl solution with the sterically less‐demanding carbene ,‐diisopropylimidazo‐2‐ylidene (IPr) yields the salt [(IPrSiCl)]Cl (‐Cl), containing a silyl cation with a Si backbone. Salt is highly reactive, but it can be used as a reagent in deuterated dichloromethane, whereby dehalogenation with MeSiOTf (OTf=OSCF) gives the dicationic silyl halide [(IPrSiCl)] . Quantum chemical calculations show that the HOMO is localized at the negatively charged central silicon atom of and , and thus although both compounds are cations they are better described as silanides, which was also corroborated by NMR investigations. : The salt [(IPrSiCl)]Cl (IPr=,‐diisopropylimidazo‐2‐ylidene), containing a silyl cation with a Si backbone, was synthesized. Dehalogenation with MeSiOSCF gives the di‐cationic silyl halide [(IPrSiCl)]. Quantum chemical calculations show that although both compounds are cations they are better described as silanides, as also corroborated by NMR investigations.

Schnepf Abstract: Does the association between household characteristics and household CO.sub.2 emissions differ for areas such as home energy, transport and indirect emissions? This question is policy relevant because distributional implications of mitigation policies may vary depending on the area of emissions that is targeted if specific types of households are likely to have higher emissions in some areas than in others. So far, this issue has not been examined in depth in the literature on household CO.sub.2 emissions. Using a representative UK expenditure survey, this paper compares how household characteristics like income, household size, education, gender, worklessness and rural or urban location differ in their association with all three areas as well as total emissions. We find that these associations vary considerably across emission domains. In particular, whilst all types of emissions rise with income, low income, workless and elderly households are more likely to have high emissions from home energy than from other domains, suggesting that they may be less affected by carbon taxes on transport or total emissions. This demonstrates that fairness implications related to mitigation policies need to be examined for separate emission domains.
