13 Jun 2016TL;DR: This work proposes a novel context aware Android smart phone based mobile adhoc sensing system that senses various data from indoor environment around the user and analyses it in real time, thereby helping to maintain good health and better work productivity.
Abstract: As humans generally spend most of their time indoors, having good indoor air quality and its real time information is critical for maintaining human health and productivity. According to EPA, indoor air even in centrally air-conditioned buildings is several times more polluted than outdoor air, primarily due to change in occupancy pattern, poor, old or ill maintained ventilation systems, dust, and presence of volatile organic compounds. Hence, it is necessary for humans to pervasively and ubiquitously measure air quality information in real time, specially whose health is sensitive to poor indoor air. In this work, we propose a novel context aware Android smart phone based mobile adhoc sensing system that senses various data from indoor environment around the user and analyses it in real time, thereby helping to maintain good health and better work productivity.

TL;DR: It is found that planar as well as buckled structure is stable for Ni-doped silicene, but the buckled sheet has slightly lower total energy and the planar silicenes sheet has unstable phonon modes.
Abstract: Silicene, a graphene analogue of silicon, has been generating immense interest due to its potential for applications in miniaturized devices. Unlike planar graphene, silicene prefers a buckled structure. Here we explore the possibility of stabilizing the planar form of silicene by Ni doping using first principles density functional theory based calculations. It is found that planar as well as buckled structure is stable for Ni-doped silicene, but the buckled sheet has slightly lower total energy. The planar silicene sheet has unstable phonon modes. A comparative study of the mechanical properties reveals that the in-plane stiffness of both the pristine and the doped planar silicene is higher compared to that of the buckled silicene. This suggests that planar silicene is mechanically more robust. Electronic structure calculations of the planar and buckled Ni-doped silicene show that the energy bands at the Dirac point transform from linear behavior to parabolic dispersion. Furthermore, we extend our study to Ge and Sn sheets that are also stable and the trends of comparable mechanical stability of the planar and buckled phases remain the same.

TL;DR: In this paper, the authors examined the relationship between bi-directional work, family enrichment, psychological capital, and supervisor support in promoting innovative work behavior and suggested interventions for facilitating innovative work behaviour.
Abstract: This paper examines the relationship between bi-directional work–family enrichment, psychological capital, and supervisor support in promoting innovative work behavior. We hypothesized that work-to-family enrichment and family-to-work enrichment would have a positive relation with psychological capital. Further, we examined that psychological capital would mediate the relationship between (i) work-to-family enrichment and innovative work behavior, and (ii) family-to-work enrichment and innovative work behavior. We also studied the role of supervisor support as a predictor or moderator for catalyzing innovative work behavior. Data were collected through questionnaire survey from 398 service-sector employees. We analyzed the data using structural equation modeling. Building on the theoretical foundation of broaden-and-build theory, we establish that both work-to-family enrichment and family-to-work enrichment were positively related to psychological capital. Psychological capital fully mediated between bi-directional enrichment and innovative work behavior. Supervisor support was directly related to innovative work behavior. We also suggest interventions for facilitating innovative work behavior.

TL;DR: A detailed electrochemical investigation of a series of iron complexes (biuret-modified tetraamido iron macrocycles FeIII -bTAML), including the first electrochemical generation of FeV (O), and demonstration of their efficacy as homogeneous catalysts for electrochemical water oxidation (WO) in aqueous medium are reported.
Abstract: A detailed electrochemical investigation of a series of iron complexes (biuret-modified tetraamido iron macrocycles FeIII -bTAML), including the first electrochemical generation of FeV (O), and demonstration of their efficacy as homogeneous catalysts for electrochemical water oxidation (WO) in aqueous medium are reported. Spectroelectrochemical and mass spectral studies indicated FeV (O) as the active oxidant, formed due to two redox transitions, which were assigned as FeIV (O)/FeIII (OH2 ) and FeV (O)/FeIV (O). The spectral properties of both of these high-valent iron oxo species perfectly match those of their chemically synthesised versions, which were thoroughly characterised by several spectroscopic techniques. The O-O bond-formation step occurs by nucleophilic attack of H2 O on FeV (O). A kinetic isotope effect of 3.2 indicates an atom-proton transfer (APT) mechanism. The reaction of chemically synthesised FeV (O) in CH3 CN and water was directly probed by electrochemistry and was found to be first-order in water. The pKa value of the buffer base plays a critical role in the rate-determining step by increasing the reaction rate several-fold. The electronic effect on redox potential, WO rates, and onset overpotential was studied by employing a series of iron complexes. The catalytic activity was enhanced by the presence of electron-withdrawing groups on the bTAML framework. Changing the substituents from OMe to NO2 resulted in an eightfold increase in reaction rate, while the overpotential increased threefold.
