Joint bibliometric analysis of patents and scholarly publications from cross-disciplinary projects : implications for development of evaluative metrics

In an attempt to develop comprehensive evidence-based methods for evaluation of the R&D performance of cross-disciplinary projects, a joint bibliometric analysis of patents and publications was performed for two industry-university-government collaborative projects aimed at commercialization: Hokkaido University Research & Business Park Project (2003-2007; 63 inventors;176 patents; 853 papers), and Matching Program for Innovations in Future Drug Discovery and Medical Care–phase I (2006-2010; 46 inventors; 235 patents; 733 papers). Besides the simple output indicators (for five years period), and citations (from the publication date to the end of 2012), science maps based on the network analysis of words and co-authorship relations were generated to identify the prominent research themes and teams. Our joint analysis of publications and patents yields objective and mutually complementing information, which provides better insights on research and commercialization performance of the large-scale projects. Hence, such analysis has potential for use in the industry-university project’s performance evaluation

Fermi surface of the organic superconductor (MDT-ST)(I3)0.417 reconstructed by incommensurate potential

The effect of incommensurate potential on Fermi surface (FS), which loses any translational symmetry in the energy bands, is investigated in the organic superconductor (MDT-ST) (I3) 0.417, where MDT-ST is 5H -2-(1,3-dithiol-2- ylidene)-1,3-diselena-4,6-dithiapentalene. The observed three fundamental Shubnikov–de Haas oscillations are explained by the reconstruction with the three times of the incommensurate anion periodicity. This unambiguously verifies the selection rule of the reconstructing vectors in incommensurate crystals. The angular magnetoresistance oscillations show that the FS has a p -type staggered corrugation with two nodes in the interlayer transfer integral

Charge transfer degree and superconductivity of the incommensurate organic superconductor (MDT-TSF)(I3)0.422

The influence of a small change of carrier number on the superconducting transition temperature Tc in the incommensurate organic superconductors is investigated for (MDT-TSF) (I3) 0.422 (MDT-TSF: methylenedithio- tetraselenafulvalene, Tc =4.9 K) in comparison with (MDT-TSF) (AuI2) 0.436 (Tc =4.5 K). Careful estimation of the degree of charge transfer by means of the Raman spectra as well as the Shubnikov–de Haas (SdH) oscillations indicates that the charge-transfer degree 0.422 for the I3 salt is obviously smaller than 0.436 in the AuI2 salt. According to the band calculation, the former salt has smaller density of states. However, the former salt exhibits higher Tc than the latter compounds, and this disagrees with the naive prediction of the BCS theory. The former salt shows considerably large effective cyclotron mass extracted from the SdH oscillations. These observations demonstrate that the strength of the many-body effect is the major factor that determines Tc in these organic superconductors
