High-performance ultraviolet detector based on self-assembled 3D/2D perovskite heterostructure.

Heterogeneous assembly of metal halide perovskites (MHPs) structures offers convenience for promoting the interfacial properties of perovskite heterojunctions, which have been widely used in the new generation of photoelectric devices. In this study, three-dimensional (3D) CsPbBr quantum dots (CPB QDs) were epitaxially grown on two-dimensional (2D) (BA)PbBr nanoplates (BPB NPs) self-assembly in a toluene mixing solution. The morphological, structural, and optical properties of the synthesized structure reveal that a highly-qualified interface and coherence were formed between the two different perovskites.

Synthesis of centimeter-size two-dimensional hybrid perovskite single crystals with tunable, pure, and stable luminescence.

The environment-friendly synthesis and property modulation of two-dimensional organic-inorganic halide perovskite (2D OHP) single crystals with large sizes and high quality are important for the fabrication of optoelectric devices. In this work, plate-like and centimeter-size (BA)Pb(BrI) (BA = -butylammonium, : 0-1) single crystals with high crystallinity were synthesized the cooling crystallization method in a mixed HX (X: I, Br) acid aqueous solution. The synthesized samples were single-phase with homogenously distributed Br and I ions.

Large Disparity between Prevalence and Treatment Rates for Hepatitis C in Western China.

Recently, the World Health Organization adopted the first-ever global hepatitis strategy with the dream of eliminating viral hepatitis as a public health threat by 2030. However, the epidemiology and treatment rates of hepatitis C virus (HCV) infection in Western China are still unknown. A total of 111,916 adult individuals (15-96 years) who underwent the HCV-antibody (HCV-Ab) test in the Second Affiliated Hospital of Chongqing Medical University between 2013 and 2015 were included in this study.

Upgrade Combination Response Is Limited by Prolonged Nucelos(t)ide Analogue Therapy in HBeAg-positive Chronic Hepatitis B: A Real-life Study.

Few previous studies have reported on a combination response (hepatitis B virus (HBV) DNA undetected, alanine aminotransferase normalization and hepatitis B e antigen (HBeAg) seroconversion) following nucleos(t)ide analogue (NAs) long-term therapy in patients with chronic hepatitis B (CHB). This study aimed to investigate the combination response on long-term NAs therapy in patients with HBeAg-positive CHB and to determine whether prolonged therapy is beneficial for combination response, particularly in optimal patients (baseline alanine aminotransferase level ≥5 upper limit of normal and HBV DNA level <10 copies/mL). In total, 280 HBeAg-positive CHB patients were enrolled in this study.
