TL;DR: The preparation of the dual composite resulting from the ordered combination of both tubular motifs is reported, envisaged that a broad range of exploitable properties may be achieved and/or controlled by varying the cyclic peptide components of similar SWCNT/SCPN hybrids.
Abstract: Two of the main types of nanotubular architectures are the single-walled carbon nanotubes (SWCNTs) and the self-assembling cyclic peptide nanotubes (SCPNs). We here report the preparation of the dual composite resulting from the ordered combination of both tubular motifs. In the resulting architecture, the SWCNTs can act as templates for the assembly of SCPNs that engage the carbon nanotubes noncovalently via pyrene “paddles”, each member of the resulting hybrid stabilizing the other in aqueous solution. The particular hybrids obtained in the present study formed highly ordered oriented arrays and display complementary properties such as electrical conductivity. Furthermore, a self-sorting of the cyclic peptides toward semiconducting rather than metallic SWCNTs is also observed in the aqueous dispersions. It is envisaged that a broad range of exploitable properties may be achieved and/or controlled by varying the cyclic peptide components of similar SWCNT/SCPN hybrids.

TL;DR: In this paper, measurements of spin correlation in top quark pair production are presented using data collected with the ATLAS detector at the LHC with proton-proton collisions at a center-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 4.6 fb(-1).
Abstract: Measurements of spin correlation in top quark pair production are presented using data collected with the ATLAS detector at the LHC with proton-proton collisions at a center-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 4.6 fb(-1). Events are selected in final states with two charged leptons and at least two jets and in final states with one charged lepton and at least four jets. Four different observables sensitive to different properties of the top quark pair production mechanism are used to extract the correlation between the top and antitop quark spins. Some of these observables are measured for the first time. The measurements are in good agreement with the Standard Model prediction at next-to-leading-order accuracy.

Abstract: We present measurements of absolute branching fractions of hadronic and lep-tonic $ D_s^{+} $ decays to K − K + π +, $ {{\overline{K}}^0} $ K +, ηπ +, μ + ν μ and τ + ν τ and report a search for the leptonic $ D_s^{+} $ → e + ν e decays The results are obtained from a data sample of 913 fb−1 collected at or near the $ \varUpsilon $ (4S) and $ \varUpsilon $ (5S) resonances with the Belle detector at the KEKB asymmetric-energy e + e − collider The branching fractions of hadronic decays are measured to be $ \begin{array}{*{20}{c}} {\mathcal{B}\left( {D_s^{+}\ \to\ {K^{-}}{K^{+}}{\pi^{+}}} \right) = \left( {506\pm 015\pm 021} \right)\%,} \\ {\mathcal{B}\left( {D_s^{+}\ \to\ {{\overline{K}}^0}{K^{+}}} \right) = \left( {295\pm 011\pm 009} \right)\%,} \\ {\mathcal{B}\left( {D_s^{+}\ \to\ \eta {\pi^{+}}} \right) = \left( {182\pm 014\pm 007} \right)\%,} \\ \end{array} $ where the first and second uncertainties are statistical and systematic, respectively The branching fractions of leptonic decays are measured to be $ \begin{array}{*{20}{c}} {\mathcal{B}\left( {D_s^{+}\ \to\ {\mu^{+}}{ u_{\mu }}} \right)=\left( {0531\pm 0028\pm 0020} \right)\%,} \\ {\mathcal{B}\left( {D_s^{+}\to {\tau^{+}}{ u_{\tau }}} \right)=\left( {570\pm 021_{-030}^{-031 }} \right)\%,} \\ \end{array} $ which are combined to determine the $ D_s^{+} $ meson decay constant $ {f_{{{D_s}}}}=\left( {2555\pm 42\pm 51} \right)\ \mathrm{MeV} $ We find no significant signal for $ D_s^{+} $ → e + ν e decays and set an upper limit of $ \mathcal{B}\left( {D_s^{+}\ \to\ {e^{+}}{ u_e}} \right) $ < 10(083) × 10−4 at 95% (90%) confidence level

TL;DR: In this paper, the authors reported the results of a study of a pulsed Fe:ZnSe laser for temperatures ranging from 85 to 295 K. The optical-to-optical efficiency of the laser was 35% at maximum energy while the maximum absorbed energy slope efficiency was as high as 51%.
Abstract: We report the results of a study of a pulsed Fe:ZnSe laser for temperatures ranging from 85 to 295 K. With a free-running Er:YAG laser, operating at 2.94 μm, as a pump source, a maximum output energy of 2.1 J at 85 K was produced at a wavelength of 4.1 μm. The optical-to-optical efficiency of the laser was 35% at maximum energy while the maximum absorbed energy slope efficiency was as high as 51%. By operating at 245 K (a temperature which can be easily reached using thermoelectric coolers) we achieved 1.3 J of output energy from an Fe:ZnSe laser, with a slope efficiency of 29% (23% optical-to-optical efficiency). The maximum output energy reached 42 mJ at room temperature (295 K). The temperature dependence of the lifetime of the 5T2 energy level of Fe2+ in ZnSe was studied in the 275–365 K temperature range. The activation energy for nonradiative relaxation was found to be 2235 cm−1.
