Platinum-perovskite nanocomposite-based Exosensor for specific detection of prostate cancer in clinical settings.

Exosomes, extracellular vesicles (EVs) with an average size of 50-150 nm, transfer various biomolecules and exchange signaling molecules between cells in a paracrine manner. Molecular investigations have revealed that EVs can reflect real-time metabolic changes in normal- and cancer-origin cells and thus harbor valid diagnostic biomarkers. Despite these advantages, the detection of low concentrations of cancer cell EVs in biological fluids is still a great challenge.

The effect of partial substitution of noble metal (Pd) at the B site of La0.6Sr0.4FeO3 as a supercapacitor electrode material.

Sol-gel combustion was used to produce the perovskite-type LaSrFeO (LSF) and LaSrFePdO (LSFP) materials and assessed as supercapacitor electrodes. The synthesized materials' crystal structure, morphology, and electrochemical performance were thoroughly analyzed. The partial substitution of Pd in the B site of the LSF structure affected the electrochemical properties of this compound and improved its performance.

Application of response surface methodology for optimization of the test condition of oxygen evolution reaction over LaBaCoO perovskite-active carbon composite.

The Experimental Design was applied to optimize the electrocatalytic activity of LaBaCoO perovskite oxide/Active Carbon composite material in the alkaline solution for the Oxygen Evolution Reaction. After the preparation of LaBaCoO, and structural characterizations, the experimental design was utilized to determine the optimal amount of the composite material and testing conditions. The overpotential was defined as the response variable, and the mass ratio of perovskite/active carbon, Potassium hydroxide (KOH) concentration, and Poly(vinylidene fluoride) (PVDF) amount were considered effective parameters.

Application of SrFeO perovskite as electrode material for supercapacitor and investigation of Co-doping effect on the B-site.

Energy storage by supercapacitors with short charging time and high power density is one of the types of electrochemical storage systems. Perovskite oxides have been significantly investigated as promising materials for energy storage in electrochemical systems. In this study, three perovskites, SrFeO, SrCoO, and SrCoFeO, were prepared using the sol-gel method and used as supercapacitor electrode materials.

Investigating the effect of non-ideal conditions on the performance of a planar CHNHPbI-based perovskite solar cell through SCAPS-1D simulation.

The difference between the simulation and experimental results of solar cells has always been challenging for researchers. Some simplifying assumptions in the simulation programs are the most common reason for this content. However, in some simulation programs, utilizing some nonidealities, the simulated solar cell can approach real conditions.
