Efficient crystal structure materials as reactive sorbent for the CO and CH adsorption and storage.

The efficient dirubidium cobalt bis(dihydrogendiphosphate) dihydrate compound is successfully synthesized in a solution and used as a reactive sorbent for the CO and CH gases adsorption and storage. A crystal of this RbCo(HPO)·2HO compound has been isolated and characterized by single X-ray diffraction analysis and was found to crystallize in the triclinic system ( ) with the cell parameters (Å): 6.980(1), 7.

Piezo inkjet formation of Ag nanoparticles from microdots arrays for surface plasmonic resonance.

The study aims to explore a novel approach for fabricating plasmonic nanostructures to enhance the optical properties and performance of various optoelectronic devices. The research begins by employing a piezo-inkjet printing technique to deposit drops containing Ag nanoparticles (NPs) onto a glass substrate at a predefined equidistance, with the goal of obtaining arrays of Ag microdots (Ag-µdots) on the glass substrate. This process is followed by a thermal annealing treatment.

An additive manufacturing approach based on electrohydrodynamic printing to fabricate P3HT:PCBM thin films.

Additive manufacturing (AM) enables the production of high value and high performance components with applications from aerospace to biomedical fields. We report here on the fabrication of poly(3-hexylthiophene): phenyl-C-butyric acid methyl ester (P3HT:PCBM) thin films through the electrohydrodynamic atomization (EHDA) process and its integration as absorber layer for organic solar cells. Prior to the film fabrication, the optimization of the process was carried out by developing the operating envelope for the P3HT:PCBM ink to determine the optimal flow rate and the appropriate applied voltage to achieve a stable-cone deposition mode.

Moderate temperature deposition of RF magnetron sputtered SnO-based electron transporting layer for triple cation perovskite solar cells.

The perovskite solar cells (PSCs) are still facing the two main challenges of stability and scalability to meet the requirements for their potential commercialization. Therefore, developing a uniform, efficient, high quality and cost-effective electron transport layer (ETL) thin film to achieve a stable PSC is one of the key factors to address these main issues. Magnetron sputtering deposition has been widely used for its high quality thin film deposition as well as its ability to deposit films uniformly on large area at the industrial scale.
