TL;DR: In this article, the authors set out the contours of Marxian urban political ecology and call for greater research attention to a neglected field of critical research that, given its political importance, requires urgent attention Notwithstanding the important contributions of other critical perspectives on urban ecology, Maoist urban political ecologists provide an integrated and relational approach that helps untangle the interconnected economic, political, social and ecological processes that together go to form highly uneven and deeply unjust urban landscapes.
Abstract: This and the subsequent papers in this special issue set out the contours of Marxian urban political ecology and call for greater research attention to a neglected field of critical research that, given its political importance, requires urgent attention Notwithstanding the important contributions of other critical perspectives on urban ecology, Marxist urban political ecology provides an integrated and relational approach that helps untangle the interconnected economic, political, social and ecological processes that together go to form highly uneven and deeply unjust urban landscapes Because the power-laden socioecological relations that shape the formation of urban environments constantly shift between groups of actors and scales, historical-geographical insights into these ever-changing urban configurations are necessary for the sake of considering the future of radical political-ecological urban strategies The social production of urban environments is gaining recognition within radical and historical-materialist geography The political programme, then, of urban political ecology is to enhance the democratic content of socioenvironmental construction by identifying the strategies through which a more equitable distribution of social power and a more inclusive mode of environmental production can be achieved

TL;DR: In this paper, a consumer benefit experienced viewpoint on value creation complements the value capture orientations of the firm positioning, transaction cost, and resource-based approaches and offers an additional tool for addressing intractable issues in strategic management.
Abstract: I show how company strategies that focus on improving consumer benefits can create value by increasing consumer payments to an entire value system. This “consumer benefit experienced” viewpoint on value creation complements the value capture orientations of the firm positioning, transaction cost, and resource-based approaches. It helps to clarify often-blurred distinctions between value creation and value capture and offers an additional tool for addressing intractable issues in strategic management.

TL;DR: The thermally-reduced GO showed p-type semiconducting behavior in ambient conditions and was responsive to low-concentration NO2 and NH3 gases diluted in air at room temperature and can be attributed mainly to the electron transfer between the reduced GO and adsorbed gaseous molecules.
Abstract: We demonstrated high-performance gas sensors based on graphene oxide (GO) sheets partially reduced via low-temperature thermal treatments. Hydrophilic graphene oxide sheets uniformly suspended in water were first dispersed onto gold interdigitated electrodes. The partial reduction of the GO sheets was then achieved through low-temperature, multi-step annealing (100, 200, and 300 ◦ C) or one-step heating (200 ◦ C) of the device in argon flow at atmospheric pressure. The electrical conductance of GO was measured after each heating cycle to interpret the level of reduction. The thermally-reduced GO showed p-type semiconducting behavior in ambient conditions and was responsive to low-concentration NO2 and NH3 gases diluted in air at room temperature. The sensitivity can be attributed mainly to the electron transfer between the reduced GO and adsorbed gaseous molecules (NO2/NH3). Additionally, the contact between GO and the Au electrode is likely to contribute to the overall sensing response because of the adsorbates-induced Schottky barrier variation. A simplified model is used to explain the experimental observations. (Some figures in this article are in colour only in the electronic version)

TL;DR: In this article, the authors compute the Galactic merger rates for NS-NS, BH-BH, and BH -BH mergers with the StarTrack code and show that the binding energy of the envelope plays a pivotal role in determining whether a binary merges within a Hubble time.
Abstract: The last decade of observational and theoretical developments in stellar and binary evolution provides an opportunity to incorporate major improvements to the predictions from population synthesis models. We compute the Galactic merger rates for NS-NS, BH-NS, and BH-BH mergers with the StarTrack code. The most important revisions include updated wind mass-loss rates (allowing for stellar-mass black holes up to 80 M {sub Sun }), a realistic treatment of the common envelope phase (a process that can affect merger rates by 2-3 orders of magnitude), and a qualitatively new neutron star/black hole mass distribution (consistent with the observed {sup m}ass gap{sup )}. Our findings include the following. (1) The binding energy of the envelope plays a pivotal role in determining whether a binary merges within a Hubble time. (2) Our description of natal kicks from supernovae plays an important role, especially for the formation of BH-BH systems. (3) The masses of BH-BH systems can be substantially increased in the case of low metallicities or weak winds. (4) Certain combinations of parameters underpredict the Galactic NS-NS merger rate and can be ruled out. (5) Models incorporating delayed supernovae do not agree with the observed NS/BH 'mass gap', in accordance with our previousmore » work. This is the first in a series of three papers. The second paper will study the merger rates of double compact objects as a function of redshift, star formation rate, and metallicity. In the third paper, we will present the detection rates for gravitational-wave observatories, using up-to-date signal waveforms and sensitivity curves.« less

TL;DR: In this paper, the authors focus on the recent development in mechanical and tribological behavior of self-lubricating metallic nanocomposites reinforced by carbonous nanomaterials such as CNT and graphene.
Abstract: Rapid innovation in nanotechnology in recent years enabled development of advanced metal matrix nanocomposites for structural engineering and functional devices. Carbonous materials, such as graphite, carbon nanotubes (CNT's), and graphene possess unique electrical, mechanical, and thermal properties. Owe to their lubricious nature, these carbonous materials have attracted researchers to synthesize lightweight self-lubricating metal matrix nanocomposites with superior mechanical and tribological properties for several applications in automotive and aerospace industries. This review focuses on the recent development in mechanical and tribological behavior of self-lubricating metallic nanocomposites reinforced by carbonous nanomaterials such as CNT and graphene. The review includes development of self-lubricating nanocomposites, related issues in their processing, their characterization, and investigation of their tribological behavior. The results reveal that adding CNT and graphene to metals decreases both coefficient of friction and wear rate as well as increases the tensile strength. The mechanisms involved for the improved mechanical and tribological behavior is discussed.
