Digital finance and renewable energy consumption:evidence from China

While digital finance and renewable energy consumption(REC)are two timely issues,it remains unclear whether the former affects the latter,especially in developing economies.This paper examines the impact of digital finance on China’s REC between 2011 and 2018 and explores the underlying mechanisms.Results show that digital finance,along with its coverage breadth and usage depth,significantly improved REC in China and that digital finance in the area of credit has had the most significant impact.Additionally,the results show that loan scale and income level are the main mediation variables,through which digital finance affects REC.The findings also suggest that economic growth and technological progress have increased REC in China,while carbon dioxide emissions have had no meaningful effect on this consumption.The results further indicate that policymakers must pay close attention to the role of digital finance when formulating policies on REC.To promote REC and environmental sustainability,developing economies like China should strengthen the breadth and depth of digital finance development,focus on the influence channels of digital finance,and promote economic growth and technological progress.

Investigation of Breaking Efficiency of N-Glycosidic Bond Between Sulfonamide and Honey

Sulfonamide residue in honey existed in a form bonded to sugar via the N-glycosidic bond.It would result in the possible underestimation of concentration of sulfonamide if it is not decomposed by chemical methods.However,in China's Mainland and Taiwan（P.R.China）,the regulation for sulfonamide residue analysis does not include hydrolysis and has been applied to a very broad range of samples,for example,egg,milk,meat,seafood as well as honey.This paper demonstrates the necessity of hydrolysis of it prior to extracting honey.The breaking efficiencies of N-glycosidic bond were investigated by 2 mol/L hydrochloric acid,pure methanol and 0.5 mol/L hydrochloric acid in methanol,respectively.It was found that acid plays the key role in breaking the N-glycosidic bond,and it was also noticed that the dissolution of liberated sulfonamide in methanol could carry the reaction forward in favor of breaking the N-glycosidic bond.

Recent advances in controlling the crystallization of two-dimensional perovskites for optoelectronic device

Though three-dimensional (3D) organic inorganic halide perovskites (OIHP) is very promising for low cost and distributed PV generation,the stability issue of 3D OIHP is still a problem for its commer-cialization.Two-dimensional (2D) perovskites,protected by periodic organic ligands,is promising due to its excellent optoelectronic property and superior stability.However,2D perovskitc is anisotropic in its crystal structure and optoelectronic properties,and the resulted film is often a mixture of different phase.So,methods to manipulate 2D perovskitc crystal orientation and its phase separation are vital.In this review,the major advances on the composition engineering,crystal orientation,phase separa-tion,and inlerfaeial capping are summarized.Besides,efforts on understanding the formation process of 2D perovskitc crystal arc also discussed,which is important for making full use of 2D perovskitc in functional optoelectronic devices.
