Article Synopsis
- The power conversion efficiency (PCE) of dye-sensitized solar cells (DSSCs) significantly relies on the semiconductor properties of titanium dioxide (TiO), which varies based on its synthesis method.
- Traditional TiO synthesis methods can be hazardous to the environment, while green synthesis using ecological solvents offers a safer alternative that minimizes toxic waste and energy use.
- In this study, tropical almond extract was utilized to control TiO growth, and doping with graphene oxide (GO) enhanced the PCE of DSSCs from 0.85% to 1.72%, indicating a promising low-cost and eco-friendly approach for improving solar cell efficiency.
Article Synopsis
- Rapid advancements in technology have enabled the production of patient-specific induced pluripotent stem cells (iPSCs), which are crucial for drug discovery and regenerative medicine.
- The diversity and volume of iPSCs created present challenges in standardizing characterization methods, as traditional assays are not suitable for high-throughput analyses.
- A new molecular assay called the TaqMan(®) hPSC Scorecard™ Panel offers a rapid and standardized approach to assess pluripotency through gene expression profiling, utilizing cloud-based analysis for comparison against validated stem cell lines.
Degradation mechanisms such as lithium plating, growth of the passivated surface film layer on the electrodes and loss of both recyclable lithium ions and electrode material adversely affect the longevity of the lithium ion battery. The anode electrode is very vulnerable to these degradation mechanisms. In this paper, the most common aging mechanisms occurring at the anode during the operation of the lithium battery, as well as some approaches for minimizing the degradation are reviewed.
View Article and Find Full Text PDFAustenitic stainless steels, widely used in food processing, undergo microstructural changes during welding, resulting in three distinctive zones: weld metal, heat-affected zone, and base metal. This research was conducted to determine the attachment of Listeria monocytogenes in these three zones before and after exposure to a corrosive environment. All experiments were done with tungsten inert gas welding of type 304 stainless steel.
