DSMC simulation of the vertical structure of planetary rings [PDF]
Astronomy & Astrophysics, 2001 A statistical Monte Carlo method (DSMC) is developed to simulate granular flows occurring in dense planetary rings. The accuracy of the method is assessed through a comparison with existing molecular dynamics simulations of the vertical structure of planetary rings with and without self-gravity eects.

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications
Advanced Materials Technologies, EarlyView.Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...
