We theoretically study the broadening of optical absorption spectra of monodisperse ensembles of randomly oriented nanorods and nanoplatelets exposed to a static electric field. It is found that the weaker quantum confinement inside nanoplatelets results in a much stronger field impact on their absorption than on the absorption of nanorods. The most notable manifestation of this impact is that the widths of the absorption lines in the nanoplatelets’ spectra peak as functions of the electric field strength. Both the maximal widths and the corresponding optimal field strengths are found to decrease with the largest dimensions of the nanoplatelets. In sharp contrast to this, the broadening of the nanorods’ absorption grows monotonously and saturates with the field strength. The high tunability of electroabsorption and the possibility to maximize its efficiency, revealed by our study, suggest semiconductor nanoplatelets as a promising material base for the next-generation electro-optic devices.

Although the theory of the socio‐cultural approach to creativity is gaining steam, empirical studies with advanced statistical tools are lagging behind. To address the gap of empirical studies integrating individual, social environmental, and cultural factors, we examined how motivational factors and environmental responsiveness were jointly related to college students’ creative achievement in different nations. Participants were university students from eight culturally and geographically diverse regions: Argentina, Austria, Chile, China, Kosovo, Russia, Saudi Arabia, and Turkey. Overall, the results painted a generally positive picture of the relationship between environmental responsiveness, motivational factors, and creative achievement. By employing structural equation modeling (SEM) and multiple‐group SEM (MGSEM) methods, results partially supported the mediation role of motivational factors between environmental responsiveness and creative achievement. In addition, we observed more consistent relationships between parental responsiveness and motivational factors or creative achievement, than lecturer. This held in common across all seven countries which fulfilled the requirements for the SEM process, indicating that parents play a potential vital role in supporting students’ motivational aspects and creative achievements, whereas lecturers supporting role is relative to the cultural organizational circumstances. As the first large‐scale empirical study with a socio‐cultural approach, we invited further discussion and proposed future cross‐cultural research of this kind. Research implications and practical suggestions were addressed.

The size dependence of the quantized energies of elementary excitations is an essential feature of quantum nanostructures, underlying most of their applications in science and technology. Here we report on a fundamental property of impurity states in semiconductor nanocrystals that appears to have been overlooked—the anticrossing of energy levels exhibiting different size dependencies. We show that this property is inherent to the energy spectra of charge carriers whose spatial motion is simultaneously affected by the Coulomb potential of the impurity ion and the confining potential of the nanocrystal. The coupling of impurity states, which leads to the anticrossing, can be induced by interactions with elementary excitations residing inside the nanocrystal or an external electromagnetic field. We formulate physical conditions that allow a straightforward interpretation of level anticrossings in the nanocrystal energy spectrum and an accurate estimation of the states' coupling strength.

Introduction: The relevance of the research is on the one hand associated with improvement of medical technologies for oncological diseases treatment contributing to increasing the patients' life expectancy, which leads to an increase of the actual quantity of oncological patients. On the other hand, it is due to worsening of the quality of life of patients having malignant tumors depending both on treatment methods and the patients' mental and emotional condition. Objective: This paper is aimed at finding psychological personal determinants that create scientific bases to allow using subjective psychological factors alongside with medical practice in working with cancer patients for improving their quality of life. Methods: The leading approach to studying this problem is the systemic and subject-based approach that allows taking an integral view of subject and personal characteristics of oncological patients. Various questionnaires focused on the coping behavior, viability and control were used as psychodiagnostic techniques for assessing the subject and personal characteristics. Results: In the paper, a review of studies is presented that deal with psychological particularities of women having breast cancer, and psychological features women with breast cancer distinguishing them from healthy women are described. As a result of the research conducted, it has been found there are personal and subjective particularities of self-control, subjective control and viability in women having breast cancer distinguishing them from healthy women. Conclusion: The materials of the paper are of practical importance for practicing psychologists who monitor and adjust the treatment process both in terms of oncologists and of psychological support, which gives the opportunity to adjust treatment methods up to the patient's mental and emotional condition.
