Article Synopsis
- Biotechnologists are developing new methods for creating transgenic plants to address challenges like climate change and pesticide resistance, focusing on using green metallic nanoparticles for DNA delivery.
- In this study, iron nanoparticles were synthesized from green tea leaf extract and Iron Chloride, and their effectiveness was tested for gene transformation in okra plants, achieving optimal results with a specific DNA to nanoparticle ratio.
- This gene transformation method, which successfully introduced the GFP gene into okra, is noted for being economical, adaptable, and environmentally friendly, potentially improving crop yield and resistance to diseases.
Electrochemical carbon dioxide reduction is a mild and eco-friendly approach for CO mitigation and producing value-added products. For selective electrochemical CO reduction, single-crystalline Au particles (octahedron, truncated-octahedron, and sphere) are synthesized by consecutive growth and chemical etching using a polydiallyldimethylammonium chloride (polyDDA) surfactant, and are surface-functionalized. Monodisperse, single-crystalline Au nanoparticles provide an ideal platform for evaluating the Au surface as a CO reduction catalyst.

Here we report catalysts comprising Pt on Ni single crystalline spines (Pt/Ni-SP) with high activity and stability for HER in alkaline solution with proposed mechanism. The Pt/Ni-SP catalysts are prepared by dispersing platinum nanoparticles (1.

Cross-sectional survey is carried out on a sample of one hundred survivors, rescuers and witness of terrorist attacks using structured interviews to assess the severity of posttraumatic stress, five months after the attacks. The study period extended from January 24, 2014 to March 24, 2014 which constitutes a total of period of 8 weeks.
