Energy conversion by surface-tension driven charge separation / Pini, Cesare ; Baier, Tobias ; Dietzel, Mathias
In this work, the shear-induced electrokinetic streaming potential present in free-surface electrolytic flows subjected to a gradient in surface tension is assessed. Firstly, for a Couette flow with fully resolved electric double layer (EDL), the streaming potential per surface stress as a function of the Debye parameter and surface potential is analyzed. [...]

Dynamics of fragmentation and multiple vacancy generation in irradiated single-walled carbon nanotubes / Javeed, Sumera ; Zeeshan, Sumaira ; Ahmad, Shoaib
The results from mass spectrometry of clusters sputtered from Cs+ irradiated single-walled carbon nano-tubes (SWCNTs) as a function of energy and dose identify the nature of the resulting damage in the form of multiple vacancy generation. For pristine SWCNTs at all Cs+ energies, C2 is the most dominant species, followed by C3, C4 and C1. [...]

Qualitative comparisons of experimental results on deterministic freak wave generation based on modulational instability / Karjanto, N ; van Groesen, E
A number of qualitative comparisons of experimental results on unidirectional freak wave generation in a hydrodynamic laboratory are presented in this paper. A nonlinear dispersive type of wave equation, the nonlinear Schr\"{o}dinger equation, is chosen as the theoretical model. [...]

Effect of surface roughness on the Goos-H\"anchen shift / Tahmasebi, Z ; Amiri, M
By considering an optically denser medium with a flat surface, but with natural roughness instead of abstract geometrical boundary which leads to mathematical discontinuity on the boundary of two adjacent stratified media, we have thus established the importance of considering physical surfaces; and thus we studied the Goos-H\"{a}nchen (GH) effect by ray-optics description to shed light on parts of this effect which have remained ambiguous. We replaced the very thin region of surface roughness by a continuous inhomogeneous intermediary medium. [...]

Excitation functions for(d,x)reactions on $^{133}$Cs up to $E_d = 40$ MeV / Tárkányi, F ; Ditrói, F ; Takács, S ; Hermanne, A ; Baba, M ; Ignatyuk, A V
In the frame of a systematic study of excitation functions of deuteron induced reactions the excitation functions of the $^{133}$Cs(d,x)$^{133m,133mg,131mg}$Ba, ${134,132}$Cs and $^{129m}$Xe nuclear reactions were measured up to 40 MeV deuteron energies by using the stacked foil irradiation technique and $\gamma$-ray spectroscopy of activated samples. The results were compared with calculations performed with the theoretical nuclear reaction codes ALICE-IPPE-D, EMPIRE II-D and TALYS calculation listed in the TENDL-2014 library. [...]

Supercritical instability of Dirac electrons in the field of two oppositely charged nuclei / Sobol, O O
The Dirac equation for an electron in a finite dipole potential has been studied within the method of linear combination of atomic orbitals (LCAO). The Coulomb potential of the nuclei that compose a dipole is regularized, by considering the finite nuclear size. [...]

A Brief History of Gravitational Waves / Cervantes-Cota, Jorge L ; Galindo-Uribarri, Salvador ; Smoot, George F
This review describes the discovery of gravitational waves. We recount the journey of predicting and finding those waves, since its beginning in the early twentieth century, their prediction by Einstein in 1916, theoretical and experimental blunders, efforts towards their detection, and finally the subsequent successful discovery..

Microscopic Processes in Global Relativistic Jets Containing Helical Magnetic Fields / Nishikawa, Ken-Ichi ; Mizuno, Yosuke ; Niemiec, Jacek ; Kobzar, Oleh ; Pohl, Martin ; Gomez, Jose L ; Dutan, Ioana ; Pe'er, Asaf ; Frederiksen, Jacob Trier ; Nordlund, AAke et al.
In the study of relativistic jets one of the key open questions is their interaction with the environment on the microscopic level. Here, we study the initial evolution of both electron$-$proton ($e^{-}-p^{+}$) and electron$-$positron ($e^{\pm}$) relativistic jets containing helical magnetic fields, focusing on their interaction with an ambient plasma.

Hydrogen in hot subdwarfs formed by double helium white dwarf mergers / Hall, Philip D ; Jeffery, C Simon
Isolated hot subdwarfs might be formed by the merging of two helium-core white dwarfs. Before merging, helium-core white dwarfs have hydrogen-rich envelopes and some of this hydrogen may survive the merger. [...]

Second ROSAT all-sky survey (2RXS) source catalogue / Boller, Th ; Freyberg, M J ; Truemper, J ; Haberl, F ; Voges, W ; Nandra, K
We present the second ROSAT all-sky survey source catalogue, hereafter referred to as the 2RXS catalogue. This is the second publicly released ROSAT catalogue of point-like sources obtained from the ROSAT all-sky survey (RASS) observations performed with the PSPC between June 1990 and August 1991, and is an extended and revised version of the bright and faint source catalogues.
