We demonstrate the growth of ultra-thin (~5 nm) indium ytterbium oxide (In-Yb-O) thin film using a simple vacuum-free aqueous solution approach for the first time. The influences of Yb addition on the microstructural, chemical, optical, and electrical properties of In2O3 are well investigated. The analyses indicate that Yb dopant could suppress oxygen vacancy defects effectively owing to the lower standard electrode potential, lower electronegativity, and stronger metal-oxide bond strength than that of In. The optimized In-Yb-O thin-film transistors (TFTs) exhibit excellent electrical performance (mobility of 8 cm2/Vs and on/off ratio of ~108) and enhanced stability. The triumph of In-Yb-O TFTs is owing to the high quality In2O3 matrix, the remarkable suppressor of Yb, and the nanometer-thin and atomically smooth nature (RMS: ~0.26 nm) of channel layer. Therefore, the eco-friendly water-induced ultra-thin In-Yb-O channel provides an excellent opportunity for future large-scale and cost-effective electronic applications.
Chronic pancreatitis (CP) is a common digestive system disease in clinic, manifested as in flammatory injury of pancreatic parenchyma and pancreatic fibrosis, and there is lack of specific treatment. However, traditional Chinese medicine can effectively improve clinical symptoms. Based on the main syndrome characteristics of CP, Chaihu Formula have been widely used in the treatment of CP with positive effect. Chaihu Formulae belong to the formula group of "Chaihu Decoction". The formulae of this class are based on Xiaochaihu Decoction, with refined drug selection, rigorous formulation and accurate drug dosage. This paper reviews the application, efficacy and research progress of Chaihu Decoction (Xiaochaihu Decoction, Dachaihu Decoction, Chaihu Shugan Powder and Chaihu Guizhi Decoction) in the treatment of CP in recent years.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
