TL;DR: In this paper, density-functional theory calculations show that an adsorbed H atom induces a spin density on the surrounding orbitals whose symmetry and degree of localization depends on the distance to the edges of the nanoribbon.
Abstract: We show how hydrogenation of graphene nanoribbons at small concentrations can open venues toward carbon-based spintronics applications regardless of any specific edge termination or passivation of the nanoribbons. Density-functional theory calculations show that an adsorbed H atom induces a spin density on the surrounding orbitals whose symmetry and degree of localization depends on the distance to the edges of the nanoribbon. As expected for graphene-based systems, these induced magnetic moments interact ferromagnetically or antiferromagnetically depending on the relative adsorption graphene sublattice, but the magnitude of the interactions are found to strongly vary with the position of the H atoms relative to the edges. We also calculate, with the help of the Hubbard model, the transport properties of hydrogenated armchair semiconducting graphene nanoribbons in the diluted regime and show how the exchange coupling between H atoms can be exploited in the design of novel magnetoresistive devices.

TL;DR: In this paper, the authors report new precise optical radial velocity measurements for these planet hosts and test the overall capabilities of CARMENES, which is an instrument that is up to the challenge of discovering rocky planets around low-mass stars.
Abstract: Context. The main goal of the CARMENES survey is to find Earth-mass planets around nearby M-dwarf stars. Seven M dwarfs included in the CARMENES sample had been observed before with HIRES and HARPS and either were reported to have one short period planetary companion (GJ 15 A, GJ 176, GJ 436, GJ 536 and GJ 1148) or are multiple planetary systems (GJ 581 and GJ 876). Aims. We aim to report new precise optical radial velocity measurements for these planet hosts and test the overall capabilities of CARMENES. Methods. We combined our CARMENES precise Doppler measurements with those available from HIRES and HARPS and derived new orbital parameters for the systems. Bona-fide single planet systems were fitted with a Keplerian model. The multiple planet systems were analyzed using a self-consistent dynamical model and their best fit orbits were tested for long-term stability. Results. We confirm or provide supportive arguments for planets around all the investigated stars except for GJ 15 A, for which we find that the post-discovery HIRES data and our CARMENES data do not show a signal at 11.4 days. Although we cannot confirm the super-Earth planet GJ 15 Ab, we show evidence for a possible long-period (P-c = 7030(-630)(+970) d) Saturn-mass (m(c) sin i = 51.8(-5.8)(+5.5) M-circle plus) planet around GJ 15 A. In addition, based on our CARMENES and HIRES data we discover a second planet around GJ 1148, for which we estimate a period P-c = 532.6(-2.5)(+4.1) days, eccentricity e(c) = 0.342(-0.062)(+0.050) and minimum mass m(c) sin i = 68.1(-2.2)(+4.9) M-circle plus. Conclusions. The CARMENES optical radial velocities have similar precision and overall scatter when compared to the Doppler measurements conducted with HARPS and HIRES. We conclude that CARMENES is an instrument that is up to the challenge of discovering rocky planets around low-mass stars.

TL;DR: In this paper, the reaction of dimethyl or diethylzinc with ketones in the presence of a stoichiometric amount of titanium tetraisopropoxide and a catalytic amount (20 mol %) of camphorsulfonamide derivatives as chiral ligands leads to the formation of the corresponding enantioenriched alcohols with enantiomeric ratios up to 94.5:5.
