We report a Raman characterization of the α borophene polymorph by scanning tunneling microscopy combined with tip-enhanced Raman spectroscopy. A series of Raman peaks were discovered, which can be well related with the phonon modes calculated based on an asymmetric buckled α structure. The unusual enhancement of high-frequency Raman peaks in TERS spectra of α borophene is found and associated with its unique buckling when landed on the Ag(111) surface. Our paper demonstrates the advantages of TERS, namely high spatial resolution and selective enhancement rule, in studying the local vibrational properties of materials in nanoscale.

People might think eating disorders are far away from them. However, eating disorders are second only to opioid addiction among the deadliest mental disorders, leading to approximately 10, 200 deaths each year. Facing such crazy data, people must pay attention to eating disorders. One of their friends might have such conditions, or even they might get eating disorders in the future. Here comes the problem: Why have eating disorders been rising recently? Carrying with such curiosity, four of us decided to write this article to figure out the cause of eating disorders. We found four factors, including sexism, abuse, social media, and discrimination, by doing research. In the following paragraphs, we will use certain logic and connections between each factor to expand the article. At the end of the article, we will discuss the future implications of our research to shed light on the psychological understanding of eating disorders and their reasons.

The transport and magnetic properties of LaAlO3/SrTiO3 (LAO/STO) heterostructure have been studied during cooling and warming.
