Multifunctional Edged-Satellite AuAg Nanoparticles-Based Integration Platform for Screening, Validation, and Elimination of Vibrio Bacteria. [PDF]

Adv Sci (Weinh)
A simple method is developed to synthesize multifunctional nanoparticles (NPs), AuAgNPs with edged satellites (ES‐AuAgNPs). These NPs demonstrate peroxidase‐like (POD‐like) activity, SERS ability, and antibacterial properties. Utilizing these multifunctional capabilities, a portable, syringe‐sized biosensor is created that integrates screening ...

Development and Characterization of Microsatellite Genetic Markers for <i>Hyalomma rufipes</i>, a Tick Vector of Crimean-Congo Hemorrhagic Fever Virus. [PDF]

Ecol Evol
This study developed and validated 14 polymorphic microsatellite markers to investigate the population genetics of Hyalomma rufipes, a tick species that transmits Crimean‐Congo Hemorrhagic Fever Virus (CCHFV) in East Africa. Ticks collected from livestock in northern Kenya were morphologically and genetically identified, followed by genome sequencing ...

Selection of a nanosatellite group separation program for cluster launching from the «Soyuz» launch vehicle orbiter

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016
The problem of selecting the parameters of nanosatellite separation from the launch vehicle orbital stage is formulated. The possibility of hazardous proximity of the nanosatellites to each other and to the orbiter of the Soyuz launch vehicle is analyzed.
