Published: April 2023

Objective: In this report, photo sensitive materials with enhanced charge carriers have been prepared using dip coating technique. Methods: Cadmium sulphide (CdS) is N-type semiconductor compound belonging to II-VI group. CdS nanoparticles were synthesized using non-aqueous chemical method and characterized by ultraviolet-visible (UV-Vis) absorption spectroscopy, photoluminescence (PL) and transmission electron microscopy. CdS films were deposited on fluorine doped tin oxide (FTO) glass slides using dip coating method at different dip times and heat treated in air and analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive analysis by X-rays (EDAX), mapping and atomic force microscopy (AFM). Results: Quantum confinement effect was observed in UV-Vis absorption spectra of CdS nanoparticles. Quenching of luminescence intensity and blue shift at smaller wavelengths were observed in PL spectra. Presence of highly dense rectangular shaped grains in CdS films and increment in particle sizes with increase in dip time were shown by AFM images. Selected area electron diffraction images showed ring patterns indicating polycrystalline nature of CdS nanoparticles. Increase in crystallite size and decrease in crystal defects by heat treatment in air and increment in grain size with increase in dip time were shown by SEM images. XRD analysis of CdS films showed polycrystalline nature. Conclusion: In previous work, preparation of dip coating deposited CdS films on FTO glass substrates for optoelectronic device applications such as photo sensors has not been reported. In this study, I-V characteristics of heterojunctions under dark and illumination conditions were discussed. Experimental results obtained in our study and their comparison with previous reports were also discussed.

Schoch Effect in Topological Phononic Crystals
Authors: Cao Yafei , Yao Yuanwei , Feng Huiping
Published: April 2023

This article investigates the Schoch negative displacement phenomenon at the interface between two-dimensional topological acoustic materials and traditional materials. The results show that a negative Schoch displacement occurs at the frequency of the Dirac point in the phononic crystal. At this point, the reciprocal of the effective bulk modulus of the phononic crystal tends to zero, making it an acoustic metamaterial with a refractive index close to zero. At the same time, the maximum value of the effective impedance of the phononic crystal and the real part of the reflection coefficient undergo a 2π phase transition at the corresponding frequency. When the phononic crystal is spliced into a topological supercell structure, a larger negative Schoch displacement is observed. This study demonstrates that topological phononic crystals can achieve negative Schoch displacement. The negative Schoch displacement realized in this article provides a new theoretical reference for designing acoustic devices based on interface waves.

The Reconstruction of Social Stratification in Post-Reform China A Study on the Formation and Impact of Social Solidification
Authors: Lao Baiqing
Published: April 2023

Drawing on past research, this essay briefly outlines the trajectory of social stratification and its structure in post-reform China, which has long been a social issue of concern. This research discusses the structure and fabric of social stratification from historical and empirical perspectives by combining government documents and historical scholarly materials. Previous studies have proved the objective fact of social solidification. This paper further discusses the features and impacts of social solidification in conjunction with Bourdieu’s capital and field theory and Pareto’s elite theory. In the post-reform era, the economic capital-centered pluralistic criteria have replaced the old political one. Nihilism in solidified China’s society can be divided into three types, escapism, hedonism, and cynicism. Social solidification and a series of social phenomena such as the second-generation phenomenon and inequality can be attributed to the relative lag and asymmetry in the interconversion of cultural and economic capital. The economic problem is a trigger that reveals social issues to some degree. This research formally analyses the relevance of social and subcultural phenomena to social stratification in post-reform China and further interprets the formation of solidification in post-reform China within different domains of capital.
Analysis of the Rules of “Necessary Measures” in Internet Service Provider’s Tort Liability
Authors: Li Jingxue
Published: April 2023

Due to the rapid development of the Internet, a large number of infringing acts occur frequently on online platforms. The traditional "necessary measures" in the form of "positioning and removal" can no longer meet the large-scale and repeated infringement of the network world today. And China's law for the "necessary measures" provisions is limited, but its extension in judicial practice and the trend of expansion for the rule has generated more controversy. This paper adopts the literature case analysis method, comparative study method and induction method to study and analyze the rule of "necessary measures" in the tort liability of network service providers. Considering that the rule originally originated from the United States of America's safe harbor principle, it is reasonable to draw on extraterritorial experience in the application. However, the improvement of the rule of necessary measures should still be combined with the characteristics of the local industry. In China, the necessary measures should be divided into types and defined in terms of form and content, which can also be judiciously determined according to the relevant definition criteria of the proportionality principle. At the same time, under general circumstances, the theoretical and judicial circles should adhere to the separation of "forwarding notice" and "necessary measures". According to the characteristics of the platform itself and the specificity of the type of services provided, the forwarding notice should be exceptionally considered as one of the necessary measures.
Reflection on the Inversion of the Burden of Proof in Environmental Infringement——Pollution Analysis by Noise and Electromagnetic Radiation
Authors: Deng Weiyi
Published: April 2023

Since the 21st century, industrialization has entered a new process, and at the same time, it has brought more environmental infringement. The traditional allocation of the burden of proof follows the principle of "who advocates who provides evidence". Due to the difficulty and complexity of proving causality, the burden of proof is reversed in environmental tort. In order to protect the vulnerable infringees in environmental tort cases, relevant laws and regulations emphasize that infringers need to bear no-fault liability. However, in practice, the inversion of the burden of proof makes most tortfeasors rely heavily on the expert opinions of professional organizations, and sometimes even become "vulnerable groups" in the evidential relationship, which leads to a large number of controversial penalties with different standards. In environmental infringement involving pollution such as sound waves and electromagnetic radiation, there are still a lot of unknowns in related research fields, which further intensifies the internal contradiction of the design of inversion of the burden of proof. Aiming at the practical problems of the inversion of the burden of proof in practice, this paper studies practical problems such as cognitive limitations, fuzzy responsibility distribution, lack of diversity, etc. Studying the environmental tort of noise and electromagnetic radiation and analyzing the application of inversion of the burden of proof will help to further improve the rules of proof of environmental tort and provide a reference for the design of subdivided laws and regulations.

Authors: Yi Xinyue
Published: April 2023

The Renaissance was an intellectual and cultural movement that took place in Europe from the mid-14th century to the 16th century, and profoundly influenced European intellectual life in the early modern period. Beginning in Italy and spreading to the rest of Europe in the 16th century, its influence is reflected in art, architecture, philosophy, literature, music, anatomy, etc. The Creation of Adam is one of the important works of this period. Michelangelo's rigorous judgment of the body on the basis of anatomy, coupled with the use of clairvoyance skills, paints a unique human beauty with a sense of power. Renaissance scholars adopted a humanistic approach in their studies and looked for realism and human emotions in art. Based on The Creation of Adam, this article provides a case study and literature analysis of the connection between art and science, especially the embodiment of anatomy in The Creation of Adam. This article offers contemporary historians and artists some thoughts on the visual language of science, including how to understand science as a craft or even as an art, understand which works are both scientific and artistic, and how to develop a new visual language for science.

As an important prerequisite for the formulation and entry into force of insurance contracts, the principle of utmost good faith is a compulsory principle that both parties should abide by. Among them, the obligation to inform is the basic obligation of the insurer to evaluate whether the subject matter of insurance is insurable and whether the policyholder chooses to sign the contract. However, in recent years, legal litigation cases caused by the insured 's obligation to inform against the principle of utmost good faith have been common. Even if the moral hazard cases of the insured 's deliberate fraud are excluded, the number of legal disputes caused by negligence should not be underestimated. Based on the analysis of the typical cases, it is undeniable that there is a " double victim "[1] phenomenon that the insurer exercises the right of rescission due to the unclear provisions of the relevant documents. Therefore, this paper hopes to summarize some incomplete explanatory loopholes in legal documents from many cases, and put forward some suggestions for improving the above loopholes and judgment methods in combination with most cases [2], so as to provide reference opinions for reducing relevant litigation cases.
