Cell Phone Use and Social Alienation of Young Teenagers

Abstract: Introduction: The aim of the study was to survey the degree of cell phone use with their dependence to it and the social alienation of young teenagers. Methods: It was a review, a survey type and in terms of application it was an observatory research on correlation between cell phone usages with student alienation in 2020. Results: The results of the research showed that there is a relationship between the degree of cell phone dependence with social alienation among users and mostly young teenagers. Conclusion: Young teenagers use cell phone much and incorrectly in some ways and times. This form of using with no more programs and freely can be called misuse of technology application and also it showed that there was a relationship between the degrees of cell phone use with the amount of feeling powerless, anomalous, senseless, social isolation or other items of social alienation. This cannot be true and correct, then a way should be found out of it

A DFT Perspective on Organometallic Lanthanide Chemistry

Computational studies of the coordination chemistry and bonding of lanthanides have grown in recent decades as the need for understanding the distinct physical, optical, and magnetic properties of these compounds increased. Density functional theory (DFT) methods offer a favorable balance of computational cost and accuracy in lanthanide chemistry and have helped to advance the discovery of novel oxidation states and electronic configurations. This Frontier article examines the scope and limitations of DFT in interpreting structural and spectroscopic data of low-valent lanthanide complexes, elucidating periodic trends, and predicting their properties and reactivity, presented through selected examples

TURBOMOLE:Today and Tomorrow

TURBOMOLE is a highly optimized software suite for large-scale quantum-chemical and materials science simulations of molecules, clusters, extended systems, and periodic solids. TURBOMOLE uses Gaussian basis sets and has been designed with robust and fast quantum-chemical applications in mind, ranging from homogeneous and heterogeneous catalysis to inorganic and organic chemistry and various types of spectroscopy, light-matter interactions, and biochemistry. This Perspective briefly surveys TURBOMOLE's functionality and highlights recent developments that have taken place between 2020 and 2023, comprising new electronic structure methods for molecules and solids, previously unavailable molecular properties, embedding, and molecular dynamics approaches. Select features under development are reviewed to illustrate the continuous growth of the program suite, including nuclear electronic orbital methods, Hartree-Fock-based adiabatic connection models, simplified time-dependent density functional theory, relativistic effects and magnetic properties, and multiscale modeling of optical properties
