- PublicationFormation and characterization of one-dimensional ZnS nanowires for ZnS/P3HT hybrid polymer solar cells with improved efficiency07-08-2023Photovoltaic performance of hybrid devices consisting of zinc sulphide (ZnS) one-dimensional (1D) nanowires and P3HT polymer was studied. As we previously reported, hybrid solar cell architecture based on ZnS, where open circuit voltage reaches high value, deserves special attention. In this work, compared to our previous research, zero-dimensional (0D) ZnS nanoparticles were replaced by one-dimensional (1D) ZnS nanowires synthesized simply with a hot injection method. In order to improve the charge transport in hybrid solar cells, additionally, the initial ligand of octadecylamine (ODA) was partially replaced by the o-phenylenediamine. The as-synthesized products were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), UV–vis spectroscopy, photoluminescence (PL) spectroscopy, energy dispersive spectroscopy (EDS), Fourier transform infrared (FT-IR) and nuclear magnetic resonance (NMR) spectroscopy. The performance of the devices significantly depended on the concentration of one-dimensional ZnS nanowires incorporated in the active layer (optimal 10 wt.%) and their morphology. In the presented work, we showed that devices based on 1D ZnS nanowires were distinguished by the high value of Voc parameter (with the maximum achieved value of 0.634 V). Also we investigated the spatial layout of nanocrystals in the device, depending on its post treatment, using atomic force microscopy (AFM), time-of-flight secondary ion mass spectrometry (TOF-SIMS) and ultraviolet photoelectron spectroscopy (UPS). Our study showed spatial segregation of nanocrystals to both interfaces with electrodes, and also we showed significant changes (0.71 eV at the top) in the PEDOT:PSS work function after mixing with ZnS nanocrystals, which resulted in an increase in the difference in contact potential at respective electrodes, which explained the high value of Voc. In comparison to our previous study, by replacing an active layer of the 0D ZnS nanocrystals with 1D ZnS nanowires, nearly a triple increase of the overall efficiency (maximum of % η of 0.568) of the device was observed.

- PublicationThe joint evaluated fission and fusion nuclear data library, JEFF-3.32020
; AbstractThe joint evaluated fission and fusion nuclear data library 3.3 is described. New evaluations for neutron-induced interactions with the major actinides$$^{235}\hbox {U}$$235U,$$^{238}\hbox {U}$$238Uand$$^{239}\hbox {Pu}$$239Pu, on$$^{241}\hbox {Am}$$241Amand$$^{23}\hbox {Na}$$23Na,$$^{59}\hbox {Ni}$$59Ni, Cr, Cu, Zr, Cd, Hf, W, Au, Pb and Bi are presented. It includes new fission yields, prompt fission neutron spectra and average number of neutrons per fission. In addition, new data for radioactive decay, thermal neutron scattering, gamma-ray emission, neutron activation, delayed neutrons and displacement damage are presented. JEFF-3.3 was complemented by files from the TENDL project. The libraries for photon, proton, deuteron, triton, helion and alpha-particle induced reactions are from TENDL-2017. The demands for uncertainty quantification in modeling led to many new covariance data for the evaluations. A comparison between results from model calculations using the JEFF-3.3 library and those from benchmark experiments for criticality, delayed neutron yields, shielding and decay heat, reveals that JEFF-3.3 performes very well for a wide range of nuclear technology applications, in particular nuclear energy. - PublicationComputational Social Science and Sociology2020
; The integration of social science with computer science and engineering fields has produced a new area of study: computational social science. This field applies computational methods to novel sources of digital data such as social media, administrative records, and historical archives to develop theories of human behavior. We review the evolution of this field within sociology via bibliometric analysis and in-depth analysis of the following subfields where this new work is appearing most rapidly: ( a) social network analysis and group formation; ( b) collective behavior and political sociology; ( c) the sociology of knowledge; ( d) cultural sociology, social psychology, and emotions; ( e) the production of culture; ( f) economic sociology and organizations; and ( g) demography and population studies. Our review reveals that sociologists are not only at the center of cutting-edge research that addresses longstanding questions about human behavior but also developing new lines of inquiry about digital spaces as well. We conclude by discussing challenging new obstacles in the field, calling for increased attention to sociological theory, and identifying new areas where computational social science might be further integrated into mainstream sociology. - PatentSposób kompostowania z funkcjonalnymi odpadami kompostowymi2020-05-06Mar Merino

- PublicationNi2P nanosheets modified N-doped hollow carbon spheres towards enhanced supercapacitor performance2021Matras-Postołek, KatarzynaCarbon materials have been attracted attention because of high supercapacitor activity. In this work, N-doped mesoporous hollow carbon spheres coated with Ni2P nanosheets are prepared by hydrothermal and calcination processes using a SiO2 template. N element doping changes the structure of hollow carbon spheres. Ni2P nanosheets are grown uniformly on the surface of the N-doped carbon spheres (N-CS). Due to the unique atomic arrangement of N-CS, the hollow mesoporous structure, and coupling with the unique composition of Ni2P nanosheets, N–C@Ni2P composites exhibit excellent electrochemical performance as supercapacitor electrodes with high specific capacitance and cycle stability under high current density.
