Gradient soft magnetic materials produced by additive manufacturing from non-magnetic powders

The changes in the magnetic properties have been attributed to the formation of the BCC phase after mixing two FCC-dominated powders. Moreover, the phase composition of the obtained gradient materials can be predicted with reasonable accuracy by the CALPHAD approach, thus providing efficient optimization of the performance. The obtained results provide new prospects for printing gradient magnetic alloy

Effect of scanning strategy on mechanical properties of Ti-6Al-4V alloy manufactured by laser direct energy deposition

In this work, we investigated the effect of DED thermal history on the obtained structural and mechanical properties of Ti-6Al-4V using a thermocouple. As a result of the study, the specific DED process parameters allow the same mechanical characteristics for as-built titanium alloy and the alloy after heat treatmen

Phase and structural changes during heat treatment of additive manufactured CrFeCoNi high-entropy alloy

In the current study, the effect of a post-printing heat treatment at 400-1000 ℃ for 24 h and for 21 days on the changes in structures and phase compositions of an AM CrFeCoNi alloy prepared by the laser powder bed fusion AM technique is presented to better understand a heat treatment-microstructure-property relationship of the AM HE

BIOINFORMATION SEARCH AND ANALYSIS OF STRUCTURES OF CRISPR/CAS SYSTEMS IN PHAGE STAPHYLOCOCUS AUREUS GENOME AND ESTIMATION OF PROFILES OF PHAGE DETECTED THROUGH CRISPR-CASSETTE BACTERIA

The emergence of resistance among the most important bacterial pathogens is generally recognized as one of the major public health problems. The most important of these organisms are penicillin-resistant Streptococcus pneumoniae, vancomycin-resistant enterococci and methicillin- and vancomycin-resistant Staphylococcus aureus. These antibiotic resistance in common pathogens have made antimicrobial therapy of many infections. Scientists need to look for new ways of treating bacterial infections in the work, using the developed algorithm from the methods of search software in the genomic structure of Staphylococcus aureus subsp. aureus ST228, the CRISPR/Cas locus and the division structures of its CRISPR cassette. The results of the bacteriophage search through the decoded spacer sequences of CRISPR-cassettes of this strain were also obtained using the developed algorithm of the software methods of bioinformatics. It was determined that the CRISPR/Cas system of strain of ST228 of S. aureus was of type IIIA. It is shown that cas-genes are in the immediate vicinity of CRISPR cassettes. The spacer structures in the detected CRISPR cassette are the Staphylococcus, Mycobacterium, Streptococcus, Bacillus, Gordonia, Arthrobacter, Streptomyces. The implementation of the algorithm of program methods for locating CRISPR/Cas-loci can be applied to many other decoded bacterial genomes to return bacteriophage therapy
