Enhanced spin-orbit coupling in hydrogenated and fluorinated graphenes studied from first principles
, 2009 The spin-orbit couplings (SOCs) of hydrogenated and fluorinated graphenes are calculated from the first principles method. It is found that the SOC-induced band splittings near their Fermi energies can be significantly enhanced to the order of 10$^{-2 ...

Deformation and Degradation in 18650 Li‐Ion Cells Under Freeze‐Thaw Cycling
Advanced Functional Materials, EarlyView.This study investigates the impact of freezethaw degradation of 18650 cells via combined electrochemical and x‐ray imaging studies. High‐resolution synchrotron X‐ray tomography reveals deformation of the jelly‐roll structure and delamination of electrode active materials in cells cycled at 1C and 4C. These structural changes are quantitatively assessed

Sampling soil organic carbon to detect change over time [PDF]
This research describes a generic monitoring design that could be widely applied to detect temporal changes in soil organic carbon stocks (SOC) across a carbon estimation area (CEA) with no prior knowledge of the spatial or temporal variance of SOC ...

Advanced Functional Materials, EarlyView.Electrochemical abuse transforms thermal runaway behavior in lithium‐ion batteries. Through systematic decoupling of degradation mechanisms, this study reveals that lithium plating lowers the onset temperature by 10 °C, electrolyte consumption delays high‐temperature reactions, and capacity fade reduces total heat generation. These mechanistic insights

Advanced Functional Materials, EarlyView.Circular photogalvanic effect measurements and first‐principles calculations reveal spin‐splitting states in solution‐processed bournonite films (CuPbSbS3) due to structural and bulk inversion asymmetry. The results provide experimental confirmation of coexisting Rashba and Dresselhaus spin‐splitting states in this non‐centrosymmetric chalcogenide ...

The Effect of Purcell Cavities on the Lifetime of Thermally Activated Delayed Fluorescent Emitters
Advanced Functional Materials, EarlyView.A pressing challenge to OLED displays and lighting is to balance high efficiency and long operational lifetime in the deep blue spectrum. The Purcell effect can reduce the triplet density and hence the probability for destructive energy‐driven triplet annihilation events that limit the OLED lifetime. Here we study of the Purcell effect on two different
