Multimodal imaging of cubic CuO@Au nanocage formation via galvanic replacement using X-ray ptychography and nano diffraction.

Being able to observe the formation of multi-material nanostructures in situ, simultaneously from a morphological and crystallographic perspective, is a challenging task. Yet, this is essential for the fabrication of nanomaterials with well-controlled composition exposing the most active crystallographic surfaces, as required for highly active catalysts in energy applications. To demonstrate how X-ray ptychography can be combined with scanning nanoprobe diffraction to realize multimodal imaging, we study growing CuO nanocubes and their transformation into Au nanocages.

Imaging CuO nanocube hollowing in solution by quantitative in situ X-ray ptychography.

Understanding morphological changes of nanoparticles in solution is essential to tailor the functionality of devices used in energy generation and storage. However, we lack experimental methods that can visualize these processes in solution, or in electrolyte, and provide three-dimensional information. Here, we show how X-ray ptychography enables in situ nano-imaging of the formation and hollowing of nanoparticles in solution at 155 °C.

Optimization of the treatment of rotavirus infection in children by using bacillus clausii.

Objective: Introduction: Rotavirus infection is a leading place in the structure of acute intestinal infections in children. Rotavirus is excreted in 40-60 % of children hospitalized with gastroenteritis all over the world. Every year, 2 million patients are hospitalized with a severe form of RVI, 25 million need medical help from a doctor and 111 million cases are treated at home.

BRAIN INTEGRATED ACTIVITY IN MEDICAL STUDENTS UNDER CONDITIONS OF ADAPTATION TO PSYCHOEMOTIONAL STRESS.

According to the results of the study the development of adaptation to psychoemotional stress, which is considered as an emotional stress in medical students during the first three years of study, has a dynamic and multifactorial character. The degree of adaptation processes' manifestation is analyzed and it is shown that it correlates with the intellectual capacity, which is based on the features of the brain integrative activity. During the study, the brain integrative activity was studied according to the information indicators of the higher (memory, internal time tracking) and central (stabilometric reaction, functional asymmetry degree) levels.
