Association between prophylactic aspirin use and hypertension using data from NHANES 2011-2018.

Aspirin may be necessary for some patients with cardiovascular disease, but previous studies on the use and dosage of aspirin and the association with hypertension have been inadequate. The results of existing studies have been somewhat inconsistent. Our study was designed to assess the association between prophylactic aspirin use and hypertension in U.

Surface Matrix-Mediated Cation Exchange of Perovskite Quantum Dots for Efficient Solar Cells.

Cesium-formamidinium lead triiodide perovskite quantum dot (CsFAPbI PQD) is very promising for photovoltaic applications due to its good phase stability and outstanding optoelectronic properties. However, achieving the CsFAPbI PQDs with tunable compositions and robust surface matrix remains a challenge. Here, the surface matrix-mediated cation exchange of PQDs is proposed, in which a bi-functional molecule, tetrafluoroborate methylammonium (FABF), is applied for the cation exchange and stabilizing surface matrix of PQDs.

Dipolar Chemical Bridge Induced CsPbI Perovskite Solar Cells with 21.86 % Efficiency.

CsPbI perovskite receives tremendous attention for photovoltaic applications due to its ideal band gap and good thermal stability. However, CsPbI perovskite solar cells (PSCs) significantly suffer from photovoltage deficits because of serious interfacial energy losses within the PSCs, which to a large extent affects the photovoltaic performance of PSCs. Herein, a dipolar chemical bridge (DCB) is constructed between the perovskite and TiO layers to lower interfacial energy losses and thus improve the charge extraction of PSCs.

Ligand exchange engineering of FAPbI perovskite quantum dots for solar cells.

Formamidinium lead triiodide (FAPbI) perovskite quantum dots (PQDs) show great advantages in photovoltaic applications due to their ideal bandgap energy, high stability and solution processability. The anti-solvent used for the post-treatment of FAPbI PQD solid films significantly affects the surface chemistry of the PQDs, and thus the vacancies caused by surface ligand removal inhibit the optoelectronic properties and stability of PQDs. Here, we study the effects of different anti-solvents with different polarities on FAPbI PQDs and select a series of organic molecules for surface passivation of PQDs.

Longitudinal Association Between Depressive Symptoms and Cognitive Function Among Older Adults: A Latent Growth Curve Modeling Approach.

Although the evidence from numerous longitudinal studies has indicated a remarkable change in cognitive function (CF) and depressive symptoms (DS) over time, the parallel latent growth curve model (LGCM) has seldom been used to simultaneously investigate the relationship between their change trajectories. This study aimed to examine whether a change in DS was associated with CF over time using an LGCM. Data were collected from the Chinese Longitudinal Healthy Longevity Survey's 2011, 2014, and 2018 waves.

Insight into the Interface Engineering of a SnO/FAPbI Perovskite Using Lead Halide as an Interlayer: A First-Principles Study.

The interfacial properties of the perovskite photovoltaic layer and electron transport layer (ETL) are critical to minimize energy losses of perovskite solar cells (PSCs) induced by interfacial recombination. Herein, the interface engineering of the SnO/FAPbI perovskite using PbX (X = Cl, Br, or I) as an interlayer is extensively studied using first-principles calculations. The results reveal that the thickness of the PbI interlayer needs to be finely controlled, which may limit charge transport if there is a large amount of PbI precipitation at the interface.
