[Parenthood and cancer: dyadic analysis of psychological distress and -health-related quality of life of cancer parents with minor children].

The purpose of this study was the analysis of psychological distress and health-related quality of life (HRQoL) of parents with minor children during curative resp. palliative treatment.Cross-sectional design with a sample of N=89 parent dyads.

Coping skills and mental health status in adolescents when a parent has cancer: a multicenter and multi-perspective study.

Objective: Parental cancer increases the risk of psychosocial problems in adolescents. We investigated the frequency and efficacy of adolescents' coping strategies and relationships between those strategies and mental health status. Age and gender differences regarding coping and mental health were also investigated.

Parental palliative cancer: psychosocial adjustment and health-related quality of life in adolescents participating in a German family counselling service.

Background: Parental palliative disease is a family affair, however adolescent's well-being and coping are still rarely considered. The objectives of this paper were a) to identify differences in psychosocial adjustment and health-related quality of life (HRQoL) among adolescents and young adults with parents suffering from palliative cancer or cancers in other disease stages, b) to relate psychosocial adjustment and health-related quality of life to adolescent coping, and c) to explore significant mediator and predictor variables.

Methods: Cross-sectional data were derived from a multi-site research study of families before child-centered counselling.

Excitonic fano resonance in free-standing graphene.

We investigate the role of electron-hole correlations in the absorption of free-standing monolayer and bilayer graphene using optical transmission spectroscopy from 1.5 to 5.5 eV.

Graphene on a hydrophobic substrate: doping reduction and hysteresis suppression under ambient conditions.

The intrinsic doping level of graphene prepared by mechanical exfoliation and standard lithography procedures on thermally oxidized silicon varies significantly and seems to depend strongly on processing details and the substrate morphology. Moreover, transport properties of such graphene devices suffer from hysteretic behavior under ambient conditions. The hysteresis presumably originates from dipolar adsorbates on the substrate or graphene surface.

Fabrication of an array of single-electron transistors for a scanning probe microscope sensor.

A technique for the fabrication of single-electron transistors (SETs) on tips for use in scanning probe microscopy is presented. The tips are micromachined out of an MBE-grown AlGaAs-GaAs heterostructure with a trench within each tip. The SETs are produced by aluminum evaporation and oxidation, and natural shadowing by the trench is used to separate the source and drain electrodes.
