space charge storage in composites thermodynamics
Physical Chemistry Chemical Physics, 2017Co-Authors: C H Chen, Joachim MaierAbstract:Contacts of two phases, which allow for synergistic dissociative storage of a component in two space charge zones (“Job-Sharing storage”), are considered from the viewpoint of point defect thermodynamics. The respective relations between charge and component activity (chemical potential of the component) are derived, or – for more complex cases – the recipes for their derivation are given. These relations describe – according to different experimental conditions – the connection between mass storage and outer partial pressure or between mass storage and the cell voltage in a coulometric titration cell. They also reflect theoretical charge/discharge curves in battery cells when Job-Sharing storage predominates, and thus are also significant for supercapacitors. In addition to explicitly worked-out cases, it is pointed out how more general situations, such as simultaneous storage in bulk and in boundaries, specific adsorption or size effects, are to be treated.

"Job-Sharing" storage of hydrogen in Ru/Li2O nanocomposites
Nano letters, 2015Co-Authors: Kun Tang, Kandavel Manickam, Thomas Bräuniger, C. Vinod Chandran, Alexander Menzel, Michael Hirscher, Dominik Samuelis, Joachim MaierAbstract:A “Job-Sharing” hydrogen storage mechanism is proposed and experimentally investigated in Ru/Li2O nanocomposites in which H+ is accommodated on the Li2O side, while H– or e– is stored on the side of Ru. Thermal desorption-mass spectroscopy results show that after loading with D2, Ru/Li2O exhibits an extra desorption peak, which is in contrast to Ru nanoparticles or ball-milled Li2O alone, indicating a synergistic hydrogen storage effect due to the presence of both phases. By varying the ratio of the two phases, it is shown that the effect increases monotonically with the area of the heterojunctions, indicating interface related hydrogen storage. X-ray diffraction, Fourier transform infrared spectroscopy, and nuclear magnetic resonance results show that a weak LiO···D bond is formed after loading in Ru/Li2O nanocomposites with D2. The storage–pressure curve seems to favor H+/H– over H+/e– mechanism.

Job-Sharing in paediatric training in Australia: availability and trainee perceptions.
The Medical journal of Australia, 2001Co-Authors: Charlotte M. Whitelaw, Margot C. NashAbstract:Objective: To examine the current availability of Job-Sharing in paediatric training hospitals in Australia and to evaluate Job-Sharing from the trainees' perspective. Design: National survey with structured telephone interviews and postal questionnaires. Setting: The eight major paediatric training hospitals in Australia. Participants: Directors of Paediatric Physician Training (DPPTs) at each hospital (or a staff member nominated by them) provided information by phone interview regarding Job-Sharing. All paediatric trainees who Job-shared in 1998 (n=34) were sent written questionnaires, of which 25 were returned. Results: Hospitals differed in terms of whether a trainee was required to give a reason for wishing to Job-share, and what reasons were acceptable. One hospital stated that two specialty units (Intensive Care and Neonatal Intensive Care) were excluded from Job-Sharing, and another stated that certain units were unlikely to be allocated Job-sharers. The remaining six hospitals said that all units were available for Job-Sharing, but the majority of their trainees disagreed. Only one hospital had a cap on the number of Job-share positions available yearly. Trainees perceived benefits of Job-Sharing to include decreased tiredness, increased enthusiasm for work, and the ability to strike a balance between training and other aspects of life. Trainees believed Job-Sharing did not adversely affect the quality of service provided to patients, and that part-time training was not of lower quality than full-time training. Conclusions: Job-Sharing in Australian paediatric training hospitals varies in terms of the number of positions available, eligibility criteria, and which units are available for Job-Sharing. In our survey, trainees' experience of Job-Sharing was overwhelminalv positive.

dual control of mitochondrial biogenesis by sirtuin 1 and sirtuin 3
Mitochondrion, 2013Co-Authors: Julia Brenmoehl, Andreas HoeflichAbstract:In this review, we discuss the dual control of mitochondrial biogenesis and energy metabolism by silent information regulator-1 and -3 (SIRT1 and SIRT3). SIRT1 activates the peroxisome proliferator activated receptor γ co-activator 1α (PGC-1α)-mediated transcription of nuclear and mitochondrial genes encoding for proteins promoting mitochondria proliferation, oxidative phosphorylation and energy production, whereas SIRT3 directly acts as an activator of proteins important for oxidative phosphorylation, tricarboxylic acid (TCA) cycle and fatty-acid oxidation and indirectly of PGC-1α and AMP-activated protein kinase (AMPK). The complex network involves different cellular compartments, transcriptional activation, post-translational modification and a plethora of secondary effectors. Overall, the mode of interaction between both sirtuin family members may be considered as a prominent case of molecular Job-Sharing.

Job Sharing for women pharmacists in academia.
American journal of pharmaceutical education, 2009Co-Authors: Kelly C. Rogers, Shannon W. FinksAbstract:The pharmacist shortage, increasing numbers of female pharmacy graduates, more pharmacy schools requiring faculty members, and a lower percentage of female faculty in academia are reasons to develop unique arrangements for female academic pharmacists who wish to work part-time. Job Sharing is an example of a flexible alternative work arrangement that can be successful for academic pharmacists who wish to continue in a part-time capacity. Such partnerships have worked for other professionals but have not been widely adopted in pharmacy academia. Job Sharing can benefit the employer through retention of experienced employees who collectively offer a wider range of skills than a single employee. Benefits to the employee include balanced work and family lives with the ability to maintain their knowledge and skills by remaining in the workforce. We discuss the additional benefits of Job-Sharing as well as our experience in a non-tenure track Job-Sharing position at the University of Tennessee College of Pharmacy.
