Thermal atomic layer deposition (TALD) and plasma atomic layer deposition (PALD) were used for producing thin NiO x films from nickel(II) acetylacetonate Ni(acac) 2 , employing different oxidizing agents (deionized water H 2 O, ozone O 3 , and molecular oxygen O 2 ). The films were deposited at 300 °C (TALD) and 220 °C (PALD) over glass substrates; their physical and chemical properties were considerably influenced by the choice of oxidizing agents. In particular, ALD(H 2 O) samples had a low growth per cycle (GPC) and a high concentration of defects. The best NiO x parameters were achieved with PALD(O 2 ), featuring high GPC (0.07 nm/cycle), high optical transparency in the visible region, electrical resistivity (1.18 × 10 4 Ω·cm), good carrier concentration (8.82 × 10 13 cm -3 ), and common mobility (5.98 cm 2 /V·s). The resulting NiO x films are polycrystalline and homogeneous in thickness and composition. According to ultraviolet photoelectron spectroscopy (UPS), work function φ and the valence band maximum E V can be tuned by the choice of the coreactant employed, with variations of up to ∼1 eV between TALD and PALD synthesis. Our results suggest that PALD permits one to achieve a better energy band alignment of NiO x and CsFAMAPbBrI perovskite, which is promising for solar cell applications., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.

Objective: To determine the clinical, diagnostic, and therapeutic profile of patients with left intraventricular thrombus (LVT) in three high-complexity centers in Medellín, Colombia, between January 2000 and January 2022., Materials and Methods: This was an observational and cross-sectional study that included 307 patients with LVT. Hospital records were analyzed to identify the clinical and therapeutic profile, and thrombus resolution and systemic embolism were evaluated. Univariate and bivariate analyses were performed using Fisher's exact test and a logistic regression model., Results: The prevalence of LVT was 9.75%. In 85% of cases, LVT was diagnosed using transthoracic echocardiography; 75.9% of patients were male, and the median age was 62 years. The most frequent comorbidities were heart failure (95.77%) and hypertension (69.7%).LVT occurred in 27% of cases in the context of acute coronary syndrome (ACS). Low molecular weight heparin (LMWH) was administered in 78.5% of cases, and warfarin was the most commonly used anticoagulant (82.7%). Hemorrhagic complications occurred in 19.2%, mainly gastrointestinal, and 35% of patients achieved thrombus resolution. Systemic embolism developed in 30% of cases, primarily affecting the central nervous system. Overall mortality was 15%., Conclusions: The prevalence of LVT was 9.75%. Warfarin remains the standard treatment, although alternative therapies are used in special cases. Apical dysfunction was associated with systemic embolism., Competing Interests: Conflictos de interés: Ninguno por declarar
