Article Synopsis
  • - The development of scalable all-perovskite tandem solar cells aims to improve efficiency compared to smaller models, but current 1-cm-scale versions are less efficient due to inhomogeneity in the materials used.
  • - A significant source of this inhomogeneity is identified at the top interface during the deposition of the electron transport layer (ETL), which affects performance.
  • - By using a mixture of 4-fluorophenethylamine and 4-trifluoromethyl-phenylammonium to create a tailored 2D perovskite layer, researchers enhanced the performance, achieving an impressive efficiency of 28.5% for all-perovskite tandem cells, marking a notable advancement

Controlling the linear growth rate, a critical factor that determines crystal quality, has been a challenge in solution-grown single crystals due to complex crystallization kinetics influenced by multiple parameters. Here we introduce a flux-regulated crystallization (FRC) method to directly monitor and feedback-control the linear growth rate, circumventing the need to control individual growth conditions. When applied to metal halide perovskites, the FRC maintains a stable linear growth rate for over 40 h in synthesizing CHNHPbBr and CsPbBr single crystals, achieving outstanding crystallinity (quantified by a full width at half-maximum of 15.

A 73-year-old woman with lung adenocarcinoma (cT4N3M1a: Stage IVA) was treated with atezolizumab as the eighth line of therapy. Four weeks after the fourth dose of atezolizumab, the prothrombin time (PT) and activated thromboplastin time (APTT) were prolonged. Coagulation factor V (FV) activity was decreased, and FV inhibitors were observed.

Article Synopsis
  • The quality of the surface on lead halide perovskite crystals significantly affects their optoelectronic properties and overall device functionality.
  • Researchers introduced a new technique that involves growing a polycrystalline film on existing bulk single crystals, resulting in crystals that emit bright green light under UV exposure.
  • The engineered crystals show fewer surface defects, leading to X-ray detectors that are nearly five times more sensitive and demonstrate greater stability compared to standard MAPbBr crystals.

Many devices heavily rely on combinatorial material optimization. However, new material alloys are classically developed by studying only a fraction of giant chemical space, while many intermediate compositions remain unmade in light of the lack of methods to synthesize gapless material libraries. Here report a high-throughput all-in-one material platform to obtain and study compositionally-tunable alloys from solution is reported.

Article Synopsis
  • * Researchers analyzed RNA-seq data from 465 blood samples, uncovering 1169 expression quantitative trait loci (eQTLs) and 1549 splice QTLs (sQTLs) linked to COVID-19 severity, including immune-related expressions.
  • * The study highlights the impact of disease severity on gene expression, identifying specific eQTLs that interact with COVID-19 phenotypes, and provides an extensive resource for understanding gene regulation in response to the virus.

Carbon-based all-inorganic CsPbIBr perovskite solar cells offer high stability against heat and humidity and a suitable band gap for tandem and semitransparent photovoltaics. In CsPbIBr perovskite films, the defects at grain boundaries (GBs) cause charge trapping, reducing the efficiency of the cell. Electronic deactivation of GB has been a conventional strategy to suppress the trapping, but at the cost of charge carrier transport through the boundaries.

Article Synopsis
  • Researchers conducted a genome-wide association study (GWAS) with 2,393 COVID-19 patients and 3,289 controls in Japan, identifying a specific genetic variant (rs60200309-A) on chromosome 5 linked to severe cases in individuals under 65.
  • The variant is more common in East Asians and associated with reduced expression of the DOCK2 gene, which was found to be lower in severe COVID-19 cases, particularly in non-classical monocytes.
  • Additionally, inhibiting DOCK2 in hamsters worsened pneumonia symptoms, indicating its potential as a biomarker and therapeutic target for severe COVID-19.

Squamous cell carcinoma of the lung is known to metastasize to the bones, but a presentation similar to bone abscess is rare. We encountered a case with bone metastases that mimicked bone abscess, which delayed the diagnosis of squamous cell lung carcinoma. A 67-year-old man presented with a left upper lung infiltrate and lytic lesions on the left first rib and right fifth rib.

The notch signaling pathway is widely conserved from vertebrates to invertebrates and mediates the specification of numerous cell fates during developmental processes. In the Xenopus gastrula embryo, Xdelta1, one of the Notch ligands, is expressed in the prospective mesoderm prior to Xbra expression. Here, we examined the role of Notch signaling in mesoderm formation.
