The spatiotemporal heterogeneity of the state of charge (SOC) within battery electrodes significantly impairs the rate capability and cycle life of lithium-ion batteries. However, mapping this heterogeneity is challenging owing to the lack of experimental methods that quantify the SOC at the electrode scale, while also offering nanoscale resolution for in-depth analyses of individual particles. Herein, this work reports an advanced projection X-ray microscopy that combines nanometric resolution, a large field of view, and high chemical sensitivity using spectroscopic imaging.

High temperatures promote kinetic processes that can drive crystal synthesis toward ideal thermodynamic conditions, thereby realizing samples of superior quality. While accessing very high temperatures in thin-film epitaxy is becoming increasingly accessible through laser-based heating methods, demonstrations of such utility are still emerging. The study realizes a novel self-regulated growth mode in the Ti-O system by relying on thermally activated diffusion of oxygen from an oxide substrate.

Article Synopsis
  • Degradable orthopedic implants made from magnesium alloys could reduce the need for surgical removal and associated pain by mimicking bone properties.
  • Previous studies indicated that pure magnesium degrades too quickly for effective bone healing, but applying hydroxyapatite coatings can slow this degradation.
  • Researchers used finite element analysis (FEA) to model and simulate the degradation of both uncoated and HA-coated magnesium over 120 days, confirming that the HA coating leads to reduced corrosion rates compared to pure magnesium.

Human leukocyte antigen (HLA) is a group of glycoproteins encoded by the major histocompatibility complex (MHC) that plays a pivotal role in the host's immune defense. Given that the MHC represents the most polymorphic region in the human genome, HLA typing is crucial in organ transplantation. It significantly influences graft rejection, graft-versus-host disease, and the overall patient outcome by mediating the discrimination between self and nonself.

Introduction: There is some evidence of a dose-response relationship for intravascular brachytherapy (IVBT) of native vessel or first-time in-stent restenosis (ISR). It has also been shown that in-field failure predominates following intravascular brachytherapy-treated lesions. Accordingly, it may be advantageous to increase the radiation dose(s) currently used.

Introduction: The use of hydroxychloroquine (HCQ) during pregnancies complicated by systemic lupus erythematosus or refractory antiphospholipid antibody syndrome has demonstrated a significant ability to prevent pre-eclampsia (PE). As such, the potential for the administration of HCQ to prevent PE in other high-risk pregnancies is an important clinical research agenda among maternal and fetal medicine specialists. Mechanistically, the anti-inflammatory and immunomodulatory effects of HCQ can offer vascular protection and inhibit the placental dysfunction-associated thrombotic changes underlying the pathophysiology of PE, fetal growth restriction (FGR) and fetal death in utero (FDIU).
