Published: November 2020

Density functional theory calculations of atomic and molecular adsorption on (111) and (100) metal surfaces reveal marked surface and structure dependent effects of strain. Adsorption in three-fold hollow sites is found to be destabilized by compressive strain whereas the reversed trend is commonly valid for adsorption in four-fold sites. The effects, which are qualitatively explained using a simple two-orbital model, provide insights on how to modify chemical properties by strain design.

Arabinoxylo-oligosaccharides (AXOS) are non-digestible dietary fibers that potentially confer a health benefit by stimulating beneficial bacteria in the gut. Still, a detailed overview of the diversity of gut bacteria and their specificity to utilize structurally different AXOS has not been provided to date and was aimed for in this study. Moreover, we assessed the genetic information of summarized bacteria, and we extracted genes expected to encode for enzymes that are involved in AXOS hydrolysis (based on the CAZy database).

Article Synopsis
  • Venezuelan equine encephalitis virus (VEEV) is a mosquito-borne virus found in Central and South America, causing disease in horses and humans during epidemics.
  • Different transmission mechanisms exist for endemic VEEV (via Culex mosquitoes and rodents) versus epidemic VEEV (via mosquitoes and horses), with mutations in viral strains leading to epizootic outbreaks.
  • The study reveals that specific RNA structures in the VEEV genome affect its ability to replicate in macrophages, highlighting the importance of genetic mutations and RNA-binding proteins in the virus's emergence and adaptation.

Venezuelan equine encephalitis virus (VEEV) is a mosquito-borne +ssRNA virus belonging to the . VEEV is found throughout Central and South America and is responsible for periodic epidemic/epizootic outbreaks of febrile and encephalitic disease in equines and humans. Endemic/enzootic VEEV is transmitted between Culex mosquitoes and sylvatic rodents, whereas epidemic/epizootic VEEV is transmitted between mosquitoes and equids, which serve as amplification hosts during outbreaks.

The combination of transition-metal (TM) elements with two-dimensional (2D) transition-metal dichalcogenides (TMDs) provides an effective route to realizing a 2D controllable magnetic order, leading to significant applications in multifunctional nanospintronics. However, in most TM atoms@TMDs nanostructures, it is challenging for the magnetic anisotropy energy (MAE) to exceed 30 meV when affected by the crystal field. Hence, the stronger magnetic anisotropy of TMDs has yet to be developed.
