Previous studies suggest pronounced health inequalities during this period but little is known about the determinants at the individual, meso- and macro-levels. We aim to further elucidate possible health inequalities during school-to-work transitions with a focus on multilevel determinants, e.g. evidence on potential effects of contextual and compositional factors of specific institutions involved. Methods We are currently conducting a scoping review (funded by the German Research Foundation) to map the evidence on the above mentioned topic among young adults (aged 16-24 years), following the methodological framework proposed by Arksey and {\´O}Malley and PRISMA. The literature search was performed in Ovid MEDLINE, Web of Science, ILO and NIOSH, using sensitive search strategy developed by text-analysis. Only articles published between January 2000 - February 2020 and written in English or German are considered. The selection process is conducted following a two-step approach:1) screening of titles and abstracts 2) screening of full-texts by two independent reviewers. Any discrepancies in the selection process are resolved by a third researcher. Preliminary Results Following the five stages of the methodological framework, the scoping review is currently in stage 3 (study selection-screening phase). We found 25,069 potentially relevant articles in our primary search. 15,508 articles remained after the duplicates were removed. Up to now, 8,825 papers were screened of which 7,629 were excluded and 1,176 included which qualified for full-text reading. Complete results of the scoping review will be presented at the conference. Conclusions This scoping review will improve our knowledge about the emergence and development of health inequalities during school-to-work transitions by examining health of individuals in different institutional contexts. Key messages - Improving our knowledge of health inequalities during school-to-work transitions. - the role of determinants at the individual, meso- and macro-levels during this stage will also be examined.}, language = {en} } @misc{LangeErnstTeubneretal., author = {Lange, Felix and Ernst, Owen C. and Teubner, Thomas and Richter, Carsten and Schmidbauer, Martin and Skibitzki, Oliver and Schroeder, Thomas and Schmidt, Peer and Boeck, Torsten}, title = {In-plane growth of germanium nanowires on nanostructured Si(001)/SiO2 substrates}, series = {Nano Futures}, volume = {4}, journal = {Nano Futures}, number = {3}, issn = {2399-1984}, doi = {10.1088/2399-1984/ab82a0}, pages = {1 -- 8}, abstract = {Germanium (Ge) nanowires (NWs) were grown in-plane on nano-structured Si(001)/SiO2 substrates by molecular beam epitaxy using gold (Au) as the solvent.

The initial growth of Ge NWs starting from Si-Au droplets with SixGe1-x nucleation from ternary alloy is discussed from a thermodynamic point of view.

Compositional and contextual characteristics of institutional contexts (e.g. kindergartens, schools) are likely to shape health inequalities among young people and may have an impact above and beyond individual-level determinants. The general research objectives of the research unit are to empirically study if characteristics of different institutional contexts are associated with the emergence of individual-level inequalities in health and c) to integrate findings from different life stages into a comprehensive theoretical model about the key mechanisms at individual and contextual levels. Methods and analysis: Building upon reviews of the existing evidence, each of the five subprojects of the research unit will analyse secondary data (cross-sectional and longitudinal surveys). The subprojects will focus on institutional contexts that serve as major socialization agents in society, such as the family, kindergarten, school, tertiary education/work, as well as the health care system. Linear or logistic multilevel modelling will be applied in order to examine the role of institutional characteristics for young people's health and health inequalities at the individual level. Ethics and dissemination: The dissemination activities include the publication of results in peer-reviewed journals, at international and national scientific conferences, as well as press releases in written and broadcast media to inform relevant stakeholders and the lay public. In the first funding stage, the research unit only uses secondary data of existing datasets. Therefore, ethical approval is not required.}, language = {en} } @misc{WachtlerHoffmannBlumeetal., author = {Wachtler, Benjamin and Hoffmann, Stephanie and Blume, Miriam and Rattay, Petra and Herr, Raphael and Deindl, Christian and Sundmacher, Leonie and Richter, Matthias and Spallek, Jacob and Lampert, Thomas}, title = {The impact of the family on health inequalities in children - A systematic scoping review}, series = {European Journal of Public Health}, volume = {30}, journal = {European Journal of Public Health}, number = {Supplement_5}, publisher = {Univ.

In this systematic scoping review we aim to provide a comprehensive overview of the available international literature on the mediating and moderating influence of the family on health inequalities in children and adolescents in Europe and North America. Methods This review follows the PRISMA guidelines for scoping reviews. After defining the research question a search strategy was developed in cooperation with a scientific librarian and the study protocol was registered. A search of three databases (Pubmed, Scopus, PsycINFO) was conducted to identify relevant literature in English or German published between the year 2000 and 2019. A qualitative data charting process was used to extract the relevant data. Results In total 11.838 records were identified through the multi database search (Pubmed n = 6370, PsycINFO n = 3505, Scopus n = 1963). After elimination of duplicates and records from excluded countries, 8862 abstracts were screened by two researchers independently. Different cluster of evidence of family influences on health inequalities were identified: Parental behaviors and children's obesity, parents' smoking and drinking habits and adolescents' risk behaviors, parenting style and children's common mental disorders, parental resources and children's quality of life. Conclusions There are different aspects of family's contextual and compositional characteristics on health inequalities identifiable in the international literature. These characteristics might be new targets for family-focused health promotion strategies.

The device is called graphene-base heterojunction transistor (GBHT). The base-voltage controls the current of the device flowing from the emitter via graphene to the collector. The transit time for electrons passing by the ultrathin graphene layer is extremely short which makes the device very promising for high frequency RF-electronics. The output current of the device is saturated and clearly modulated by the base voltage. Further, the silicon collector of the GBHT is replaced by germanium to improve the device performance. This enabled the collector current to be increased by almost three orders of magnitude. Also, the common-emitter current gain (Ic/Ib) increased from 10-3 to approximately 0.3 for the newly designed device. However, the ON-OFF ratio of the improved germanium based GBHT has so far been rather low.

In this study, we fabricated and analyzed a novel graphene-based transistor, which resembles the structure of the barristor but uses a different operating condition. This new device, termed graphene adjustable-barriers transistor (GABT), utilizes a semiconductor-based gate rather than a metal-insulator gate structure to modulate the device currents. The key feature of the device is the two graphene-semiconductor Schottky barriers with different heights that are controlled simultaneously by the gate voltage. Due to the asymmetry of the barriers, the drain current exceeds the gate current by several orders of magnitude. Thus, the GABT can be considered an amplifier with an alterable current gain. In this work, a silicon-graphene-germanium GABT with an ultra-high current gain (ID/IG up to 8 × 106) was fabricated, and the device functionality was demonstrated. Additionally, a capacitance model is applied to predict the theoretical device performance resulting in an on-off ratio above 106, a swing of 87 mV/dec, and a drivecurrent of about 1 × 106 A/cm2.}, language = {en} }
