TL;DR: Oligochitosan samples varying in molecular weight (M w ) and having narrow polydispersities were prepared by means of depolymerization of chitosans in hydrochloric acid, and their antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA) was measured at pH values 5.5-8.0 as mentioned in this paper.
Journal ArticleDOI

Vladimir G. Sevastyanov,Elizaveta P. Simonenko,Nikolay P. Simonenko,Valentina L. Stolyarova,Sergey I. Lopatin,Nikolay T. Kuznetsov +5 more
TL;DR: In this article, the vaporization behavior of neodymium and gadolinium hafnates with pyrochlore structure was examined in the temperature range 2100-2750 K.
Journal ArticleDOI
Obtaining chitin, chitosan and their melanin complexes from insects
TL;DR: Insects serve as an alternative source of chitin, which forms up to 40% of their exoskeleton, and can enhance each other's biological activity, providing a wide range of potential applications.
Journal ArticleDOI
Mass spectrometric study of thermodynamic properties in the Yb2O3‐ZrO2 system at high temperatures
TL;DR: The thermodynamic functions found in the Yb2O3-ZrO2 system at 2400 K, such as the activities of components and the Gibbs energy of formation, displayed negative deviation from ideality.
Journal ArticleDOI
High-temperature thermodynamic properties of the Al2O3-SiO2 system
TL;DR: In this article, high-temperature mass spectrometry is used to investigate vaporization processes and determine SiO2 activity in the Al2O3-SiO2 system between 1850 and 1970 K. The results are consistent with the known phase equilibria in this system.
