Growing interests have been devoted to the design of polymer acceptors as potential replacement for fullerene derivatives for high-performance all polymer solar cells (all-PSCs). One key factor that is limiting the efficiency of all-PSCs is the low fill factor (FF) (normally <0.65), which is strongly correlated with the mobility and film morphology of polymer:polymer blends. In this work, we find

Density dependent growth and optical properties of periodic arrays of GaAs nanowires (NWs) by fast selective area growth MOVPE are investigated. As the period of the arrays is decreased from 500 nm down to 100 nm, a volume growth enhancement by a factor of up to four compared with the growth of a planar layer is observed. This increase is explained as resulting from increased collection of precurs

Background: Chemoattractant receptor-homologous molecule expressed on T helper type 2 (Th2) cell (CRTh2) receptor antagonists is being investigated for asthma. Objectives: The aim of this study was to assess the effects of the CRTh2 receptor antagonist, AZD1981 (with/without inhaled corticosteroids [ICSs]), on lung function and asthma control. Patients and methods: Adults aged 18–60 years were enr

We address H-infinity state feedback and give a simple form for an optimal control law applicable to linear time invariant systems with symmetric and Hurwitz state matrix. More specifically, the control law as well as the minimal value of the norm can be expressed in the matrices of the system's state space representation, given separate cost on state and control input. Thus, the control law is tr

Among truthmaker theorists it is generally thought that we are not able to use the entailment principle (i.e. the principle according to which truthmaking distributes across entailment) to ground negative truths. But these theorists usually only discuss truthmakers for truth-functional complexes, thereby overlooking the fact that there are non-truth-functional complexes whose truth values are not

In this article, we briefly identify three main challenges/issues that should be taken into consideration in the institutionalization of entrepreneurship research: (1) recognizing the complexity of the phenomenon under study; (2) producing interesting, relevant and useful research results for all stakeholders; and (3) developing a critical posture in research. Following the discussion of these cha

This book synthesizes 30 years of research on business angels by charting the significant role they play in the financing of entrepreneurial businesses in both developed and emerging economies. The expert group of contributors examine business angels themselves, the evolution of the market and the role of public policy in influencing angel investment. Finally, the editors provide an agenda for fut

In the chapter the authors revisit one of the original topics in business angel research: to measure the scope of the business angel market and evaluate its impact on the economy, especially the financial contributions of business angels at the macro (market) level. This is an issue that has considerable policy relevance. Most policy initiatives to support business angel activities have been intro

We used temperature programmed reaction spectroscopy (TPRS) and synchrotron-radiation based photoelectron spectroscopy (PES) to investigate the adsorption and oxidation of methanol (CH3OH) on Tb2O3(111) and TbO2(111) thin films grown on Pt(111). We find that methanol mainly desorbs from the Tb2O3 surface through both molecular and recombinative processes, and that a relatively small amount of adso

The growth, morphology, structure, and stoichiometry of ultrathin praseodymium oxide layers on Ru(0001) were studied using low-energy electron microscopy and diffraction, photoemission electron microscopy, atomic force microscopy, and X-ray photoelectron spectroscopy. At a growth temperature of 760 [degree]C, the oxide is shown to form hexagonally close-packed (A-type) Pr2O3(0001) islands that are

Small leucine-rich proteoglycans interact with other extracellular matrix proteins and are important regulators of matrix assembly. Fibromodulin has a key role in connective tissues, binding collagen through two identified binding sites in its leucine-rich repeat domain and regulating collagen fibril formation in vitro and in vivo Some nine tyrosine residues in the fibromodulin N-terminal domain a

As animals move through their environments they are subjected to an endless barrage of sensory signals. Of these, some will be of utmost importance, such as the tell-tale aroma of a potential mate, the distinctive appearance of a vital food source or the unmistakable sound of an approaching predator. Others will be less important. Indeed some will not be important at all. There are, for instance,

A quick guide to the diverse and unusual eyes of polychaete fan worms, by Michael Bok and Dan-Eric Nilsson.

Feces is an abundant, rich source of energy, utilized by a myriad of organisms, not least by members of the order Diptera, i.e., flies. How Drosophila melanogaster reacts to fecal matter remains unclear. Here, we examined oviposition behavior toward a range of fecal samples from mammals native to the putative Southeast African homeland of the fly. We show that D. melanogaster display a strong ovip
