A comprehensive study on carrier mobility and artificial photosynthetic properties in group VI B transition metal dichalcogenide monolayers
TL;DR: In this paper, the authors compared the room temperature carrier mobilities calculated in group-VI B TMDC (i.e., MX2) monolayers via a systematic comparison of reliable models used within the framework of density functional theory and incorporated piezoelectric effects on carrier mobility.

Group-IV(A) Janus dichalcogenide monolayers and their interfaces straddle gigantic shear and in-plane piezoelectricity.
TL;DR: Inversion symmetry in the 1T-phase of pristine dichalcogenide monolayer MX2 (M = Ge, Sn; X = S, Se) is broken in their Janus structures, which induces an in-plane piezoelectric coefficient, d22 = 4.09 (2.15) pm V−1 and a shear piezo-lectric coefficients, d15 = 7.90 (13.68) pmV−1 in the GeSSe (SnSSe) monolayers as mentioned in this paper.

Solar Energy Harvesting in Type II van der Waals Heterostructures of Semiconducting Group III Monochalcogenide Monolayers
TL;DR: In this paper, the type II van der Waals (vdW) heterobilayers of six group III chalcogenide monolayers (MX, M = Ga, In; X = S, Se, Te) have been systematically investigated and compared with the pristine v...

Superhigh out-of-plane piezoelectricity, low thermal conductivity and photocatalytic abilities in ultrathin 2D van der Waals heterostructures of boron monophosphide and gallium nitride
TL;DR: The emergence of high piezoelectricity, high carrier mobility, low lattice thermal conductivity and photocatalytic water splitting abilities in the proposed vdW heterobilayer signifies enormous potential for its versatile applications in nanoscale energy harvesting, e.g., nano-sensors in medical devices, future nanopiezotronics, 2D thermoelectrics and solar energy conversion.

Nano-hives for plant stimuli controlled targeted iron fertilizer application
TL;DR: In this article, the chitosan coating on iron powder loaded mesoporous silica has been found to control the above undesired soil reaction, which closed the pores in the presence of carbonate ions to keep the iron in phyto-available forms, whereas open the pores for the uptake proton signal from the roots.
