"Time-of-Flight Small-Angle Neutron Scattering instrument Bilby: capabilities and performance"

Dr Anna Sokolova (Instrument scientist, Small-Angle Neutron Scattering Australian Centre for Neutron Scattering, ANSTO, Australia)

 

Bilby is a ToF Small-Angle Neutron Scattering machine at Australian Centre for Neutron Scattering (ACNS) at ANSTO, Sydney, Australia. The instrument is in operation from 2015, with more than 50 papers published. The talk will consist of several parts: SANS instruments at ACNS; Bilby main design features and mono- ToF options; scientific highlights, soft and hard matter.

"The main research directions of paleoecology"

A.V. Pakhnevich

 

Alexey Valentinovich Pakhnevich PhD in Biology, Senior Researcher Paleontological Institute, named after A.A., Borisyak, RAS

Paleoecology is the science that studies the interactions of extinct organisms with each other and with the environment. The report will be devoted to the analysis of the relationship of ancient organisms in populations and communities (= biocenoses). Examples of trophic connections, reconstruction of habitat conditions by finding characteristic species of plants and animals, the content of various minerals, chemical elements and their isotopes in the skeletons will be considered. The study of these issues is associated with the use of modern research techniques. Examples of their use will be demonstrated in the report.

"Application of neutron activation analysis and other methods in materials science"

Aleksiayenak Y.V.

 

The report will present the results of work carried out jointly with the Scientific-Practical Materials Research Centre of the National Academy of Sciences of Belarus (SSPA "Scientific-Practical Materials Research Centre"), Minsk, Belarus. Currently, the fields of application of composite materials (composites) are very wide, ranging from mechanical engineering to electronics. Composites based on copper disulfide, which serves as the basis for solar energy converters; composites based on cubic boron nitride, Ti, and Al, which can be used in high-energy and high-temperature electronics, solid-state dosimetry, have been investigated. The obtained composites were analyzed by X-ray diffraction and scanning electron microscopy. Neutron activation analysis was used to determine impurities in composite materials synthesized at the Scientific-Practical Materials Research Centre, to determine the optimal conditions for synthesis, and to identify sources of impurities, for that purpose the elemental composition of the synthesis equipment and burden materials was studied.
