A Theoretical Study of the Electron-Surface Optical Phonon Interaction in Monolayer Transition Metal Dichalcogenides Deposited on SiC and hexagonal BN Dielectric Substrates in the Vicinity of the Points () of the Brillouin Zone.

We theoretically investigated the electron-surface optical phonon interaction across the long-range Fröhlich coupling in monolayer transition metal dichalcogenides, such as WS, WSe, MoS, and MoSe monolayers, on SiC and hexagonal BN dielectric substrates. We employed the effective Hamiltonian in the K+(K-) valley of the hexagonal Brillouin zone to assess the electronic energy shifts induced by the interaction between electronic states and surface polar optical phonons. Our results indicate that the interaction between electrons and surface optical phonons depends upon the polar nature of the substrate.

Analysis of Entropy Generation for Mass and Thermal Mixing Behaviors in Non-Newtonian Nano-Fluids of a Crossing Micromixer.

This work's objective is to investigate the laminar steady flow characteristics of non-Newtonian nano-fluids in a developed chaotic microdevice known as a two-layer crossing channels micromixer (TLCCM). The continuity equation, the 3D momentum equations, and the species transport equations have been solved numerically at low Reynolds numbers with the commercial CFD software Fluent. A procedure has been verified for non-Newtonian flow in studied geometry that is continuously heated.

Assessment of pesticide contamination in hill reservoirs: combination of a rainfed farming survey and water multiresidue monitoring (Lebna watershed, Cap Bon, Tunisia).

Due to Mediterranean climatic conditions, traditional pluvial agrosystems are widespread along the southern Mediterranean shore and were previously thought to have minimal impact on surface water resources due to low agricultural input levels. However, current pesticide applications are now considered to contribute significantly to the contamination of surface water resources, which may result in severe impacts on biodiversity and the environment. This study examined the presence and mobility risk of pesticides in the surface waters of the Lebna watershed in northeastern Tunisia, a rainfed Mediterranean agricultural region.

Interactions Between [PdX] (X=Cl, Br) Dianions in Presence of Counterions.

The interaction between two square palladium (II) dianions PdX (X=Cl, Br) is evaluated by crystal study and analyzed by quantum chemical means. The arrangement within the crystal between each pair of PdX neighbors is suggestive of a Pd⋅⋅⋅X noncovalent bond, which is verified by a battery of computational protocols. While the potential between these two bare dianions is computed to be highly repulsive, the introduction of even just two counterions makes this interaction attractive, as does the presence of a constellation of point charges.

Synergistic Effects of BaTiO and MFeO (M = Mn, Ni, Cu, Zn, and Co) Nanoparticles as Artificial Pinning Centers on the Performance of YBaCuO Superconductor.

Large-scale superconductor applications necessitate a superconducting matrix with pinning sites (PSs) that immobilize vortices at elevated temperatures and magnetic fields. While previous works focused on the single addition of nanoparticles, the simultaneous inclusion of different nanoparticles into a superconducting matrix can be an effective way to achieve an improved flux pinning capacity. The purpose of this study is to explore the influence of mixed-nanoparticle pinning, with the co-addition of non-magnetic (BaTiO; BT) and various types of magnetic spinel ferrite (MFeO, abbreviated as MFO, where M = Mn, Co, Cu, Zn, and Ni) nanoparticles, on the superconductivity and flux pinning performances of the high-temperature superconductor YBaCuO (YBCO).
