On the nature and limits of alkaline earth-triel bonding.

The synthesis of a series of isostructural organometallic complexes featuring Ae-Tr bonds (Ae = Be, Mg; Tr = Al, Ga, In) has been investigated, and their electronic structures probed by quantum chemical calculations. This systematic study allows for comparison, not only of the metal-metal bonding chemistries of the two lightest alkaline earth (Ae) elements, beryllium and magnesium, but also of the three triel (Tr) elements, aluminium, gallium, and indium. Computational analyses (NBO, QTAIM, EDA-NOCV) reveal that Be-Tr bonding is more covalent than Mg-Tr bonding.

Diberyllocene, a stable compound of Be(I) with a Be-Be bond.

The complex diberyllocene, CpBeBeCp (Cp, cyclopentadienyl anion), has been the subject of numerous chemical investigations over the past five decades yet has eluded experimental characterization. We report the preparation and isolation of the compound by the reduction of beryllocene (BeCp) with a dimeric magnesium(I) complex and determination of its structure in the solid state by means of x-ray crystallography. Diberyllocene acts as a reductant in reactions that form beryllium-aluminum and beryllium-zinc bonds.

Conceptual framework of the recovery of self-awareness following a severe traumatic brain injury in childhood.

Introduction: Self-awareness following a TBI in childhood is an under-represented area of research in the pediatric literature. The issue is well described in the adult literature but the theories and practice recommendations in this body of literature are not easily transferable to pediatric neurorehabilitation. Children and young people sustain a TBI at a time when the brain is yet to fully develop.

Young People's Experiences of Returning to Physical Leisure Activities after a Severe Acquired Brain Injury.

Aims: To understand the experiences of young people returning to physical leisure activities following a severe acquired brain injury (ABI).

Methods: Seven young people (5 male; 14-19 years) participated. Semi-structured interviews were conducted with young people who sustained a severe ABI 1-3 years prior to the study.

In-line measurements of the physical and thermodynamic properties of single and multicomponent liquids.

Microfluidic devices are becoming increasingly important in various fields of pharmacy, flow chemistry and healthcare. In the embedded microchannel, the flow rates, the dynamic viscosity of the transported liquids and the fluid dynamic properties play an important role. Various functional auxiliary components of microfluidic devices such as flow restrictors, valves and flow meters need to be characterised with liquids used in several microfluidic applications.
