TL;DR: It has been established that a postannealing of N-graphene after gold intercalation causes a conversion of the N environment from pyridinic to graphitic, allowing to obtain more than 80% of all embedded nitrogen in graphitic form, which is essential for the electron doping in graphene.
Abstract: A novel strategy for efficient growth of nitrogen-doped graphene (N-graphene) on a large scale from s-triazine molecules is presented. The growth process has been unveiled in situ using time-dependent photoemission. It has been established that a postannealing of N-graphene after gold intercalation causes a conversion of the N environment from pyridinic to graphitic, allowing to obtain more than 80% of all embedded nitrogen in graphitic form, which is essential for the electron doping in graphene. A band gap, a doping level of 300 meV, and a charge-carrier concentration of ∼8 × 1012 electrons per cm2, induced by 0.4 atom % of graphitic nitrogen, have been detected by angle-resolved photoemission spectroscopy, which offers great promise for implementation of this system in next generation electronic devices.

TL;DR: In this article, the authors show the results of spectral analyses of treering data from northern Sweden and show that only a few peaks in the spectra are consistently significant when the data are analyzed over a number of sub-periods.
Abstract: Quantitative estimates of 1480 years of summer temperatures in northern Fennoscandia have previously been derived from continuous treering records from northern Sweden. Here we show the results of spectral analyses of these data. Only a few peaks in the spectra are consistently significant when the data are analyzed over a number of sub-periods. Relatively timestable peaks are apparent at periods of 2.1, 2.5, 3.1, 3.6, 4.8, ∼ 32–33 and for a range between ∼ 55–100 years. These results offer no strong evidence for solar-related forcing of summer temperatures in these regions. Our previously published reconstruction was limited in its ability to represent long-timescale temperature change because of the method used to standardize the original tree-ring data. Here we employ an alternative standardization technique which enables us to capture temperature change on longer timescales. Considerable variance is now reconstructed on timescales of several centuries. In comparison with modern normals (1951–70) generally extended periods when cool conditions prevailed, prior to the start of the instrumental record, include 500–700, 790–870, 1110–1150, 1190–1360, 1570–1750 (A.D.) with the most significant cold troughs centred on about 660, 800, 1140, 1580–1620 and 1640. Predominantly warm conditions occurred in 720–790, 870–1110 and 1360–1570 with peaks of warmth around 750, 930, 990, 1060, 1090, 1160, 1410, 1430, 1760 and 1820.

TL;DR: It is argued that in a biological fluid, proteins associate with nanoparticles, and it is the amount and presentation of the proteins on the surface rather than the particles themselves that are the cause of numerous biological responses.

TL;DR: It is reported that ALK5 is important for TGFbeta/ALK1 signaling; endothelial cells lacking AlK5 are deficient in TGF beta/ALK 1-induced responses and that theALK5 kinase activity is required for optimal ALK1 activation.

TL;DR: It is found that the differences are only minor, and it is concluded that software engineering students may be used instead of professional software developers under certain conditions.
Abstract: In many studies in software engineering students are used instead of professional software developers, although the objective is to draw conclusions valid for professional software developers. This paper presents a study where the difference between the two groups is evaluated. People from the two groups have individually carried out a non-trivial software engineering judgement task involving the assessment of how ten different factors affect the lead-time of software development projects. It is found that the differences are only minor, and it is concluded that software engineering students may be used instead of professional software developers under certain conditions. These conditions are identified and described based on generally accepted criteria for validity evaluation of empirical studies.
