NANOSTRUCTURES (Cu,Zn)/h-BN FOR HETEROGENEOUS CATALYSIS

(Cu,Zn)/h-BN heterogeneous nanostructures were successfully synthesized by wet chem-istry reaction. Metal nanopartciles, 10-20 nm in dimension, were homogeneously distributed over the BN support. Nanocatalysts showed high catalytic activity in CO oxidation reaction.Работа выполнена при финансовой поддержке Российского Научного Фонда (соглашение № 20-79-10286)

PT/H-BN NANOSTRUCTURES DEVELOPMENT FOR HETEROGENEOUS CATALYSIS

Pt/h-BN hybrid nanostructures were successfully synthesized by the impregnation method. Pt nanopartciles, 3-10 nm in size, were homogeneously distributed on over the BN support. Nanocatalysts showed high catalytic activity in CO oxidation, full conversion was achieved at 184 °С.Работа выполнена при финансовой поддержке Российского научного фонда (проект № 20-79-10286)

Advances in the use of terminal restriction fragment length polymorphism (T-RFLP) analysis of 16S rRNA genes to characterize microbial communities

Terminal restriction fragment length polymorphism (T-RFLP) analysis is a popular high-throughput fingerprinting technique used to monitor changes in the structure and composition of microbial communities. This approach is widely used because it offers a compromise between the information gained and labor intensity. In this review, we discuss the progress made in T-RFLP analysis of 16S rRNA genes and functional genes over the last 10 years and evaluate the performance of this technique when used in conjunction with different statistical methods. Web-based tools designed to perform virtual polymerase chain reaction and restriction enzyme digests greatly facilitate the choice of primers and restriction enzymes for T-RFLP analysis. Significant improvements have also been made in the statistical analysis of T-RFLP profiles such as the introduction of objective procedures to distinguish between signal and noise, the alignment of T-RFLP peaks between profiles, and the use of multivariate statistical methods to detect changes in the structure and composition of microbial communities due to spatial and temporal variation or treatment effects. The progress made in T-RFLP analysis of 16S rRNA and genes allows researchers to make methodological and statistical choices appropriate for the hypotheses of their studies.Ursel M. E.
