Direct Synthesis of Semiconductive AgBiS NC Inks toward High-Efficiency, Low-Cost and Environmental-Friendly Solar Cells.

Silver bismuth sulfide nanocrystals (AgBiS NCs) embody a pioneering heavy-metal-free photovoltaic material renowned for its ultrahigh absorption coefficient, offering promising opportunities for advancing the field of ultra-thin and biocompatible solar cells. Currently, the fabrication of AgBiS NC photovoltaic devices relies on hot-injection synthesis and subsequent tedious ligand exchange, leading to high production cost, complex processes and environmental pollution. Here, we developed a direct-synthesis (DS) method without ligand-exchange for AgBiS NC semiconductive inks, significantly simplifying the material preparation and device fabrication processes.

Clinical characteristics and risk factors of connective tissue disease complicated with bronchiectasis and pulmonary infection.

The clinical data from 118 CTD patients with bronchiectasis were collected and categorized into two groups: pulmonary infection present (n = 67) and absent (n = 51), for comparative analysis of characteristics and risk factors. Then, we analyzed and compared their demographics, disease characteristics, and risk factors for infection. Among the whole cohort (n = 118), the incidence of pulmonary infections was 56.
