Photoexcitation of C₆₀-WSe₂ hybrids for optical sensing

Description: Article discusses a study on synthesizing 0D-2D vdW heterostructure by spin coating C60 molecules on halide-assisted-low-pressure chemical-vapor-deposition (HA-LPCVD) produced monolayer WSe2 flakes. The study reveals that WSe2-C60 hybrid system is an appealing choice for next generation optical sensing devices.

Stability and degradation in triple cation and methyl ammonium lead iodide perovskite solar cells mediated via Au and Ag electrodes

Description: Article focuses on the fact that there are no clear mechanisms for the interaction of electrode-induced absorber degradation pathways. Furthermore, the authors hypothesize that the formation of AgI in the PSCs, leads to corrosion of the perovskite absorber, as opposed to the benign AuI when Au electrodes are used in the solar cell stack.

A Phosphonic Functionalized Biopolymer for the Sorption of Lanthanum (III) and Application in the Recovery of Rare Earth Elements

Description: Authors of the article state that in the first step of their experiment, the sorption was investigated using La(III) ions before testing for the recovery of rare earth elements (REEs) from pretreated industrial acidic leachate. They infer that phosphonate groups participate in the sorption, and that the most effective sorption is at pH = 4.
