The further development of economy research is discussed from the viewpoint of methodology. On the basis of detailed discussion of three methods. a correlation is established between the macroocopic level (the leed of the overall system) and the microscopic level (the level of the molecule)in statistical Physics. Analysis is conducted of the application of these methods to economics. The concept of economic entropy is proposed into the economic system.

Developing a bridge capping layer between perovskite and hole transport layer materials(HTMs) in the n-i-p perovskite solar cells(pero-SCs) is an effective approach to modify the morphology of HTMs and passivate the perovskite ***, we select the quinoxaline-based bifunctional passivation agent, quinoxalin-6-yl-methylamine hydrochloride(QxMACl),as the bridging layer, and a D-A copolymer PBQ12.containing the same quinoxaline unit as an HTM for the n-i-p pero-SCs. Due to the π-π stacking among the common quinoxaline units in the bridge layer and HTM, QxMACl induces the π-π stacking of the PBQ12.film and improves the film morphology of HTMs with better conductivity. Additionally, QxMACl can effectively passivate the perovskite surface, and PBQ12.possesses appropriate energy levels and high hole mobility. The pero-SCs based on FAPbI3with PBQ12.QxMACl treatment showed a higher power conversion efficiency(PCE) of 2..05% and outstanding stability, maintaining 95.4% and 92.1% of its initial PCE after 750 h of storage and after over 800 h of thermal annealing at85 °C, respectively. To further enhance the PCE of the PBQ12.QxMACl-based devices, we developed a non-metal ion dopant for the PBQ12.HTM. Through trace doping of PBQ12.HTM by the non-metal ion dopant, the PCE of the PBQ12.QxMACl-based devices reached 2..2.%(the calibrated PCE of 2..55% by the National Institute of Metrology, china).

Free cholesterol has been considered to be a critical risk factor of nonalcoholic fatty liver disease(NAFLD).It remains unknown whether dietary intake of condensed tannins(CTs)have distinguishable effects to alleviate liver damage caused by a high cholesterol *** C57BL/6 mice were fed a high cholesterol diet for 6 weeks,and given CTs treatment at a dosage of 2.0 mg/(kg·day)at the same *** results indicated that compared with mice fed a {1. diet,a high cholesterol diet group resulted in significant weight loss,dysregulation of lipid metabolism in blood and liver,and oxidative stress in the liver,but CTs treatment dramatically reversed these negative *** and eosin(H&E)staining and frozen section observation manifested that CTs treatment could effectively reduce the deposition of liver cholesterol and tissue necrosis caused by high cholesterol *** alleviated liver injury mainly by regulating the expression of related genes in cholesterol metabolism pathway and AMPK *** results confirmed that CTs have remarkable cholesterol lowering and anti-liver injury effects in vivo.
