TL;DR: Modern methods of graphene production and functionalization are surveyed with an emphasis on the development of chemical sensors and fuel cell electrodes with brief comparisons to state-of-the-art carbon nanotube-based systems.
Abstract: Graphene, an atomically thin layer of sp2 hybridized carbon, has emerged as a promising new nanomaterial for a variety of exciting applications including chemical sensors and catalyst supports. In this article, we survey modern methods of graphene production and functionalization with an emphasis on the development of chemical sensors and fuel cell electrodes with brief comparisons to state-of-the-art carbon nanotube-based systems.

TL;DR: The aerodynamic and acoustic performance of an anechoic wind tunnel test section with walls made from thin Kevlar cloth have been measured and analyzed as discussed by the authors, where the cloth contains the bulk of the flow but permits the transmission of sound with little loss.

TL;DR: In this paper, the ability of n-alkanethiolates chemisorbed at Au(111) to function as boundary lubricants at microscopic length scales as probed by scanning force microscopy (SFM) was explored.
Abstract: This paper explores the ability of n-alkanethiolates chemisorbed at Au(111) to function as boundary lubricants at microscopic length scales as probed by scanning force microscopy (SFM). Through an examination of the influence of alkyl chain length, we show that the macroscopic structure of this system, as developed from insights into the chain-packing density via infrared reflection spectroscopy, greatly influences the observed friction and wear. That is, the longer chain monolayers exhibit a markedly lower friction and a reduced propensity to wear than the shorter chain monolayers, a situation that reflects the more extensive cohesive interactions between chains. From the combined weight of these findings, we examine the frictional process within the context of an activation mechanism that involves pressure and shear activation volumes. The ability of longer chain alkanethiolate monolayers to lubricate features that arise from changes in substrate topography is also presented, and the resulting mechanist...

TL;DR: In this paper, a steady state PQ-diagram for a variable speed wind turbine equipped with a Doubly Fed Induction Generator was derived, and the authors concluded that the limiting factor regarding reactive power production will typically be the rotor current limit and that the limit for reactive power absorption will be the stator current limit.
Abstract: The aim of the work is to derive a steady state PQ-diagram for a variable speed wind turbine equipped with a Doubly Fed Induction Generator. Firstly, the dependency between optimal rotor speed and wind speed is presented. Secondly, the limitations in reactive power production, caused by the rotor current, the rotor voltage and the stator current are derived. Thirdly, the influence of switching from Δ to Y coupling of the stator is investigated. Finally, a complete PQ diagram for a wind turbine is plotted. It is concluded that the limiting factor regarding reactive power production will typically be the rotor current limit, and that the limit for reactive power absorption will be the stator current limit. Further, it is concluded that the rotor voltage will only have a limiting effect at high positive and negative slips, but near the limitation, the reactive power capability is very sensitive to small changes in the slip.
