Nicknames of English-Speaking Adolescent Users of Social Networks (on the Example of Twitter)

The features of the self-nomination of English-speaking adolescents in Internet communication - in a social network such as Twitter microblogging are discussed in the article. The focus of the article is the anthroponymic units of Internet communication - nicknames belonging to Internet users of the age group of 12-17 years. The relevance of the study is determined by the need to fill up research gaps in socio-, psycho- and ontolinguistics, as well as the unflagging attention of philologists to the anthropocentric aspects of Internet communication. The novelty lies in an integrated approach to the consideration of the features, methods and means of naming teenagers on Twitter. The nominative potential of nicknames is analyzed. In accordance with the nature of the constitutive token, self-nomination groups of autonomous, pseudonymous, and transitional types are distinguished. Conclusions are drawn about the characteristics of the anonymity of teenage names on Twitter (the degree of anonymity and its expressiveness). The authors also dwell on the structural aspect of virtual individual names, identifying the most productive models of property creation in virtual space. The results of a graphical analysis of the research material are presented, accompanied by a quantitative characteristic of paraverbal means. The analysis has established a correlation between the psychological new formations of adolescents and the characteristics of their nicknames on Twitter. It is shown that the inconsistency and originality of the considered stage of the ontogenetic development of users is projected onto their self-nomination

Laser synthesis of ruby for photo-conversion of solar spectrum

Ruby grains are synthesized by laser heating of the dry mixture of Al$_2$O$_3$ and Cr$_2$O$_3$. Quasi-continuous radiation of a Nd:YAG laser was used for this purpose with average power of 15 W. Synthesized ruby grains demonstrate strong photo-luminescence in the vicinity of 700 nm. Synthesized ruby grains were integrated into a matrix made of flouro-polymer. Luminescene map acquired with the help of a photo-fluorimeter confirms efficient photo-conversion of green-blue radiation of the synthesize ruby into red region. Ruby grans can further be fragmented to smaller particles using the technique of laser fragmentation in liquids
