Aiming at the low luminous-efficiency of two-dimensional (2D) perovskite, its quantum yield (QY) and stability are effectively improved by a fluorinated second insulator layer 3,4-difluoroaniline (F2PA) outside first 2-(2,4-difluorophenyl) ethylamine (FPEA). The QY perovskite with two layers is 3.4-time in contrast counterpart one insulator, which originates from defect suppression reduction ex...

The Warm Plasma Dispersion Relation, for waves in the electron cyclotron resonance range of frequencies, can be cast into form a bi-quadratic equation $N_\perp$, where coefficients are function $N_\perp^2$ and an iterative procedure is required to obtain solution. However, this not well understood fails converge towards solution at second harmonic layer. In particular higher densities wave coup...

The surface finish is critical for applications such as micro-fluid mixing and self-assembly that requires smooth fluidic flow and mechanical rotation respectively. However, in layer-based additive manufacturing processes, it is well known that the stair-stepping effect exists in the fabricated surfaces since a three-dimensional model is approximated by a set of two-dimensional layers. The fabr...

Today, a 34m global equivalent water layer (GEL) lies in the Martian polar-layered deposits and shallow ground ice. During the Amazonian, 3m was outgassed, and 31m was lost to space and to the surface, leaving 62m at the end of Hesperian. During the Hesperian, volcanic outgassing added 5m, 7m was lost, and 40m GEL of groundwater was added to form outflow channels, leaving 24m carryover of surfa...

This paper presents CFD simulations of natural displacement ventilation airflows in which the buoyancy force produced by a heat source is opposed by a wind force. Cases investigated focus on windbuoyancy force relationships for which a two-layer stratification is maintained. CFD predictions of the position of the interface separating the two layers and the change in reduced gravity (temperature...
