We calculate the strength of effective onsite Coulomb interaction (Hubbard $U$) in two-dimensional (2D) transition-metal (TM) dihalides MX$_2$ and trihalides MX$_3$ (M=Ti, V, Cr, Mn, Fe, Co, Ni; X=Cl, Br, I) from first principles using constrained random-phase approximation. The correlated subspaces are formed $t_{2g}$ or $e_g$ bands at Fermi energy. Elimination efficient screening taking place...

Pixel by pixel TI mapping of MR images has been used in conjunction with image analysis techniques to study the lumbar vertebral bone marrow of 20 patients with refractory or relapsed Hodgkin's disease prior to salvage chemotherapy, or high dose chemotherapy with autologous bone marrow rescue. Compared to 18 age matched controls, seven patients had significantly abnormal lumbar vertebral marrow...

First-principles thermodynamic models based on the cluster expansion formalism, monte-carlo simulations and quantum-mechanical total energy calculations are employed to compute short-range-order parameters and diffuse-antiphase-boundary energies in hcp-based α-Ti-Al alloys. Our calculations unambiguously reveal a substantial amount of SRO is present in α-Ti-6 Al and that, at typical processing ...

We demonstrate, for the first time, the growth of metastable single-phase NaCl-structure high-AlN-content Ti1-xAlxN alloys (x ≤ 0.64) which simultaneously possess high hardness and low residual stress. The films are grown using a hybrid approach combining high-power pulsed magnetron (HPPMS/HIPIMS) and dc magnetron sputtering of opposing metal targets. With HIPIMS applied to the Al target, Al n+...
