Giant Orbital Rashba–Edelstein Effect in Crystalline Cu2O/Cu Heterostructures
Advanced Materials, EarlyView.An enhanced orbital Rashba–Edelstein effect is demonstrated in a crystalline Cu2O/Cu heterostructure, compared to naturally oxidized CuOx structures, highlighting the critical role of crystallinity and interface control in orbital torque generation. The resulting spin torque conductivity exceeds that of Pt, indicating the potential of orbital torque ...

Evolutionary sequences for red giant stars
The Astrophysical Journal Supplement Series, 1978 A set of 46 evolutionary sequences has been computed for stars ascending the red giant branch for the first time. These red giant sequences, extending from the subgiant branch to the onset of helium burning within the core, cover the following ranges in the helium abundance Y, the heavy-element abundance Z, and the mass M:0.10< or =Y< or =0.40, 0.00001<

Advanced Materials, EarlyView.Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Testing the Breakdown of the Asteroseismic Scaling Relations in Luminous Red Giants
The Astrophysical JournalNearly all cool, evolved stars are solar-like oscillators, and fundamental stellar properties can be inferred from these oscillations with asteroseismology.

Revisiting the Activity–Rotation Relation for Evolved Stars
The Astrophysical JournalThe magnetic dynamo mechanism of giant stars remains an open question, which can be explored by investigating their activity–rotation relations with multiple proxies. By using the data from the LAMOST and Galaxy Evolution Explorer surveys, we carried out

Estimation of Distances to the Red Giant Stars [PDF]
, 1995 [Abstract] Based on the Principal Component Analysis and Oort's Galactic rotation model, the distances to the red giant stars are estimated. The 157 red giant stars are devided into two groups, then the distances are estimated as log d(Kpc)=0.471z_2+0 ...

Advanced Materials, EarlyView.Crystal orientation and domain engineering enable bulk mirror symmetry breaking in Bi1−xSbx, resulting in ultralow current‐induced switching of perpendicular magnetization without an external field. By exploiting single‐domain Bi1−xSbx (012), the authors demonstrate an out‐of‐plane spin Hall conductivity of ∼1.12×105ℏ2eΩ−1m−1$ \sim \!1.12 \ensuremath ...

Metallicity of the Double Red Clump in the Milky Way Bulge
The Astrophysical JournalWe present a reanalysis of the metallicity of the double red clump (RC) stars from the Milky Way bulge. Two leading explanations for the existence of the double RC concern possible differences in chemical composition (multiple populations of stars) or ...
