Organometal perovskite single crystals have been recognized as a promising platform for high-performance optoelectronic devices, featuring high crystallinity and stability. However, a high trap density and structural nonuniformity at the surface have been major barriers to the progress of single crystal-based optoelectronic devices. Here, the formation of a unique nanoisland structure is reported at the surface of the facet-controlled cuboid MAPbI(3) (MA = CH3NH3+) single crystals through a cati...

Abstract null null This study reports the first experimental research of Ecklonia radiata macroalga as novel precursor material for the synthesis of one-dimensional Silicon carbide (1D-SiC) Nanoceramics. High-temperature carbothermic reduction of Biosilica (Bio-SiO2) at 1550 °C under controlled Argon purge is proposed as means of facile scalable bulk manufacturing method. The synthesis, characterization, and potential applications of the reaction products are discussed. The experimental results ...

A direct thin film approach to fabricate large surface MoS 2 nanosheet thin film supercapacitors using the solution-based diffusion of thiourea into an anodized MoO 3 thin film is investigated. A dense MoS 2 nanosheet thin film electrode (D-MoS 2 ) was obtained when the anodized MoO 3 thin film was processed in a low thiourea solution concentration whereas a highly porous MoS 2 nanosheet thin film electrode (P-MoS 2 ) was formed at a higher thiourea solution concentration. The charge storage per...

Abstract Lithium carbonate and lithium hydroxide are two compounds used for producing battery cathodes, however, lithium hydroxide is favoured in producing battery compounds as it possesses very high electrochemical potential and low density. As a result, there is substantial demand for development of anion-selective membranes capable of selecting hydroxide over carbonate. Although single-layer nanosheets of Layered Double Hydroxides (LDHs) have shown anion conductivity, the reassembling of the ...

Surfactants are frequently employed in the fabrication of polymer/graphene-based nanocomposites via emulsion techniques. However, the impact of surfactants on the electrical and mechanical properties of such nanocomposite films remains to be explored. We have systematically studied the impact of two anionic surfactants [sodium dodecyl sulfate (SDS) and sodium dodecyl benzene sulfonate (SDBS)] on intrinsic properties of the nanocomposite films comprising reduced graphene oxide in a matrix of poly...

We present a subnanometer scale study of the interface between crystalline silicon (c-Si) and aluminum oxide (AlO _{x}) deposited by an industrial type, remotely plasma-enhanced chemical vapor deposition (PECVD) system. We investigate the origin of the negative charge density within the AlO _{x}layer and the interface defect density. In order to elucidate the source of the negative charge in subnanoscale, we study various AlO _{x}layers with different properties, such as total charge (Q...
