First-principles calculations to investigate structural, elastic, electronic, thermodynamic, and thermoelectric properties of CaPd3B4O12 (B = Ti, V) perovskites

Results in Physics, 2022
This study has explored numerous physical properties of CaPd3Ti4O12 (CPTO) and CaPd3V4O12 (CPVO) quadruple perovskites employing the density functional theory (DFT) method. The calculated lattice constants show inclinable compliance with the experimental

DESIGN AND PARAMETER OPTIMIZATION OF A DOUBLE-CONE WHEAT PLOT SEED-METERING DEVICE BASED ON EDEM [PDF]

Engenharia Agrícola
The traditional wheat plot seed-metering device is hampered by poor seed dispersion uniformity and a long seed falling time. To improve upon these characteristics, in this paper, we designed a double-cone combined seed-metering device.

Application of Biosurfactant Obtained from Eichhornia Crassipes in the Removal of Petroderivate in Sand and Water from the Sea

Chemical Engineering Transactions, 2020
Oil spills and oil products destroy terrestrial and marine ecosystems. One solution to this is the use of biosurfactants. Biosurfactants are able to solubilize oil stains in soil and water. The intense reproduction of Eichhornia crassipes leads to a high

Attempt to fabricate a high thermal conductivity, transparent oxide glass by dispersing MgO crystals and refractive index matching

AIP Advances, 2018
Oxide glasses generally have low thermal conductivity due to their disordered structures. Here, a fabrication method to provide them with high thermal conductivity while retaining their optical transparency is proposed.

New method to identify optimal discontinuity set number of rock tunnel excavation face orientation based on Fisher mixed evaluation

Underground Space
Discontinuity is critical for strength, deformability, and permeability of rock mass. Set information is one of the essential discontinuity characteristics and is usually accessed by orientation grouping.
