AI Article Synopsis
- The study explores how varying the antisolvent temperature during the washing enhanced nucleation (WEN) process affects the properties of CHNHPbI crystalline thin films and the performance of MAPbI photovoltaic cells.
- The characterization techniques used include atomic-force microscopy, X-ray diffractometry, and photoluminescence spectrometry, revealing a shift in the crystalline phase from (110)-(002) complex to a preferred (002) phase as temperature changes.
- The highest power conversion efficiency of the MAPbI photovoltaic cells reaches 19.30% at an antisolvent temperature of 30 °C, attributed to improved carrier collection efficiency and reduced carrier recombination.
Article Abstract
The properties of CHNHPbI(MAPbI) crystalline thin films and the device performance of highly efficient MAPbIphotovoltaic cells are investigated by varying the temperature of the antisolvent from 20 °C to 50 °C during the washing enhanced nucleation (WEN) process. The surface, structural, optoelectronic and defect properties of the perovskite thin films are characterized through atomic-force microscopy, X-ray diffractometry and photoluminescence spectrometry. The experimental results show that changing the temperature of the antisolvent during the WEN process can manipulate the MAPbIcrystalline thin films from the (110)-(002) complex phase to a (002) preferred phase. It is noted that the highest power conversion efficient of the inverted MAPbIphotovoltaic cells is 19.30%, mainly due to the increased carrier collection efficiency and reduced carrier recombination when the temperature of the antisolvent is 30 °C.

A Bioabsorbable Implant Seeded with Adipose-Derived Stem Cells for Adipose Regeneration.

Adipose tissue engineering requires effective strategies for regenerating adipose tissue, with adipose-derived stem cells (ASCs) being favored due to their robust self-renewal capacity and multipotent differentiation potential. In this study, the efficacy of poly-L-lactic acid (PLLA) mesh containing collagen sponge (CS), seeded with ASCs to promote adipose tissue formation, was investigated. PLLA-CS implants seeded with GFP-positive ASCs were inserted at high concentration (1 × 10 cells/implant, H-ASC) and low concentration (1 × 10 cells/implant, L-ASC), as were unseeded controls.

Aluminum is a well-known and widely distributed environmental neurotoxin. This study aimed to investigate the effect of miR-98-5p targeting insulin-like growth factor 2 (IGF2) on aluminum neurotoxicity. Thirty-two Sprague-Dawley rats were randomly divided into four groups and administered 0, 10, 20, and 40 μmol/kg maltol aluminum [Al(mal)], respectively.

Scaffolds made from cartilage extracellular matrix are promising materials for articular cartilage repair, attributed to their intrinsic bioactivity that may promote chondrogenesis. While several cartilage matrix-based scaffolds have supported chondrogenesis and/or , it remains a challenge to balance the biological response (e.g.

In pediatric hematopoietic cell transplantation (HCT) recipients, transplanted donor cells may need to function far beyond normal human lifespan. Here, we investigated the risk of clonal hematopoiesis (CH) in 144 pediatric long-term HCT survivors and 258 non-transplanted controls. CH was detected in 16% of HCT recipients and 8% of controls, at variant allele frequencies (VAFs) of 0.

Single-nucleus RNA sequencing (snRNA-seq), an alternative to single-cell RNA sequencing (scRNA-seq), encounters technical challenges in obtaining high-quality nuclei and RNA, persistently hindering its applications. Here, we present a robust technique for isolating nuclei across various tissue types, remarkably enhancing snRNA-seq data quality. Employing this approach, we comprehensively characterize the depot-dependent cellular dynamics of various cell types underlying mouse adipose tissue remodeling during obesity.
