Authors: Yu Wenkai
Published: December 2024

In recent years, stock prices have risen and fallen sharply, so that investors cannot be expected to accurately determine when to buy shares, thus greatly reducing the number of people participating in the stock market. Based on some data and the description of pictures, this paper draws some conclusions. The Internet can help the stock market further expand its influence and create conditions for solving the imbalance between supply and demand in China's structural finance. On the other hand, for new energy companies, resources such as international oil prices will have a negative relationship with their stock prices, leading to the inability to achieve real profits. Establish a carbon emission trading market that focuses on the relationship between climate change and financial risk, corporate governance and policy making to meet emission reduction targets and promote sustainable development. International oil prices have a positive relationship with the share prices of traditional fossil energy companies, while those of new energy companies have a negative relationship. It can be seen that the stock price of new energy companies is usually accompanied by varying degrees of volatility, which makes investors feel anxious every day.

As the world shifts toward a more sustainable society, the advancement of high-performance lithium-ion battery (LIB) technology becomes increasingly vital in addressing rising CO2 levels. The necessity for higher energy density, propelled by the progression of electric vehicles, hybrid electric vehicles, and portable electronics, has highlighted the limitations of traditional graphite anodes. Silicon-based anodes, with their superior theoretical capacity, present a promising alternative. This paper explores the working mechanisms of LIBs and delves into why silicon is an ideal material for anodes. It also delivers an exhaustive overview of Si-based electrodes, emphasizing the significant challenges they face, such as extreme volume expansion and unstable solid electrolyte interface (SEI) formation, which contribute to a shortened battery lifespan. Potential solutions, including nanostructured designs and novel binder formulations, are discussed, highlighting their advantages and current limitations. The benefits and challenges of Si-based materials as LIB anodes are summarized to guide future research and development in this critical area.
A Systematic Analysis of The Current 2D Perovskite Engineering Approach and Future Prospects

Perovskite solar cells (PSCs) have become a hot topic in the photovoltaic studies. Although perovskite has excellent photoelectric properties including adjustable bandgap, high power conversion efficiency (PCE) performance, high electron transport, the three-dimensional perovskite commonly studied is often unstable, short life, and subject to environmental interference especially heat and humidity. So two-dimensional perovskites have been studied and studied. This paper introduces the 2D materials and 2D perovskite solar cells. And then several new works of surface engineering on 2D perovskite solar cells including passivation strategies, interface engineering and orientation of crystallization on perovskite films are mentioned and concluded, thereby providing a future understanding to improve and balance the efficiency and stability of 2D PSCs. Even though the existing strategies for optimizing two-dimensional perovskite are abundant and have certain rules, more essential two-dimensional perovskite properties to improve efficiency and stability need to be studied, so that two-dimensional perovskite will have more possibilities in industrial production.

In this study, the vulnerability of foreigners to crime in India is examined, with a particular emphasis on the article, which offers an account of a research project that looks at the many crimes committed against Indian expats and investigates their root reasons. The t-test is used to identify significant variations in instances over two years, and the ANOVA statistical tool is used to identify significant overall changes in the victimization rate. The National Crime Records Bureau of India's official website (https://ncrb.gov.in/en/crime-india) served as the study's data source. The data show that the most common crimes committed against Indian foreigners are theft, robbery, and assault. Most of these incidents take place in well-known tourist locations and big cities. The survey also underlines the difficulties foreigners encounter when reporting crimes to the Indian police, such as language hurdles and a lack of legal knowledge. This study intends to contribute to the development of effective solutions to reduce victimization risks and improve the overall experience of foreign tourists in India by addressing the causes and effects of crimes against Indian foreigners.
