詳細

アプリケーション

• Coupling of gene regulation and carrier modification manipulates bacterial biofilms as robust living catalysts: This research explores the application of potassium dichromate as a catalyst in biotechnological processes, particularly in the modification of bacterial biofilms. These developments show significant promise for bioengineering, where robust living catalysts can play critical roles in industrial bioprocessing and environmental remediation (Yan CH et al., 2024).


• Exploring the synergistic effect of chromium (Cr) tolerant Pseudomonas aeruginosa and nano zero valent iron (nZVI) for suppressing Cr uptake in Aloe Vera: This study uses potassium dichromate to investigate the effects of chromium exposure on plants and the potential mitigating actions of bioremediation techniques. It highlights the importance of using potassium dichromate in environmental science to assess and develop strategies for managing heavy metal contamination in agriculture (Komal et al., 2024).


• Preparation and properties of oxidized multi-walled carbon nanotube superhydrophobic composites modified by bio-fatty acids: Potassium dichromate is used here as an oxidizing agent in the synthesis of advanced nanocomposite materials. These materials are significant for their applications in creating superhydrophobic surfaces, which have broad implications in material science and industrial manufacturing, particularly for coatings and environmental applications (Hao X et al., 2024).


• An internal filtration effect-based "off-on" probe for fluorescent and visual sensing of formaldehyde: In this research, potassium dichromate′s role as a chemical reagent in analytical methods is highlighted. It is used to develop sensitive and specific sensors for detecting hazardous substances like formaldehyde, underscoring its critical role in enhancing public health and safety protocols within laboratory and industrial settings (Fan W et al., 2024).
