TL;DR: In this article, the authors discuss the geodynamical and geophysical environments which are necessary for planets where plate tectonics remain active over geological time scales and for planets which evolve to one-plate planets.
Abstract: This work reviews factors which are important for the evolution of habitable Earth-like planets such as the effects of the host star dependent radiation and particle fluxes on the evolution of atmospheres and initial water inventories. We discuss the geodynamical and geophysical environments which are necessary for planets where plate tectonics remain active over geological time scales and for planets which evolve to one-plate planets. The discoveries of methane–ethane surface lakes on Saturn’s large moon Titan, subsurface water oceans or reservoirs inside the moons of Solar System gas giants such as Europa, Ganymede, Titan and Enceladus and more than 335 exoplanets, indicate that the classical definition of the habitable zone concept neglects more exotic habitats and may fail to be adequate for stars which are different from our Sun. A classification of four habitat types is proposed. Class I habitats represent bodies on which stellar and geophysical conditions allow Earth-analog planets to evolve so that complex multi-cellular life forms may originate. Class II habitats includes bodies on which life may evolve but due to stellar and geophysical conditions that are different from the class I habitats, the planets rather evolve toward Venus- or Mars-type worlds where complex life-forms may not develop. Class III habitats are planetary bodies where subsurface water oceans exist which interact directly with a silicate-rich core, while class IV habitats have liquid water layers between two ice layers, or liquids above ice. Furthermore, we discuss from the present viewpoint how life may have originated on early Earth, the possibilities that life may evolve on such Earth-like bodies and how future space missions may discover manifestations of extraterrestrial life.

TL;DR: This essay seeks to identify the contributions that strategy and organizational researchers have made, and continue to make, in enhancing the authors' understanding of a wide variety of important corporate governance questions.
Abstract: In this essay, we seek to identify the contributions that strategy and organizational researchers have made, and continue to make, in enhancing our understanding of a wide variety of important corporate governance questions. We begin by discussing how these research contributions stem from a willingness to draw from and contribute to different streams of intellectual thought, and we provide an orienting framework to situate this work.

TL;DR: In this article, photoactive condensed carbon nitride nanorods (CNRs) can be obtained via confined thermal condensation of cyanamide inside the nanochannels of an anodic alumni oxide (AAO) membrane template.
Abstract: Photoactive, condensed carbon nitride nanorods (CNRs) can be obtained via confined thermal condensation of cyanamide inside the nanochannels of an anodic alumni oxide (AAO) membrane template. The promotion of a more condensed network of CNRs with lowered HOMO in water splitting (including both H2 and O2 revolution) and photocurrent output was demonstrated.

Journal ArticleDOI
TL;DR: In this article, the authors measured the concentration profiles of oxygen in the liquid phase and obtained the kLa data of the various liquid phases which only depend on the gas velocity, adjusting the experimental profiles with the predictions of the axial dispersed plug flow model.
