What is the speed of #electron-transfer reaction in biological cells, systems/Processes? Nature has decided the optimal speed of electron-transfer reaction in biological cells, systems/Processes to achieve optimal speed of cationic/anionic electron reaction, speed of DNA replication, speed of transcription Speed of Cell division, Speed of cell proliferation, etc. We also know that if speed of electron-transfer reaction,  speed of #DNA replication, speed of transcription, Speed of Cell division, Speed of cell proliferation become abnormal/more than desired, then diseases such as Cancer is a proof of concept. At organism level, another proof of concept on the speed of electron-transfer reaction,  speed of DNA replication, speed of transcription, Speed of Cell division, Speed of cell proliferation is Rabbit with more speed than Turtle, life of Rabbit is 15 Years and of Turtle is more than 300 Years.  In philosophical and biological contexts, abnormal speed/more than desired over speed set by Nature will lead to loss of survival/loss of dynamics/loss of equilibrium etc. In the same analogy, #Artificial systems, #AI-things/Machines etc. are known for reducing time/increased efficiency/achieve amplified action with the help of high speed of electron-transfer reaction in the forms of data processing, input/output, performance, action etc. so what would be influence of Artificial systems, AI-things/Machines etc. in the future convergence/equilibrium/Optimal/Balanced/sustainable world?

Check out this interesting video from the American Chemical Society. A recent study investigated the deformation behaviors of gallium-based liquid metals in acidified cupric sulfate or cupric chloride solutions. The findings provide valuable information into the deformable behavior of these liquid metals and their potential applications in soft machines and electronics. Key takeaways: - The deformation rate of the liquid metal increases with higher concentrations of chloride ions and decreases with higher concentrations of sulfate ions. - The formation of hydrated cupric cations and cupric-chloro complexes plays an important role in the deformation process. - The addition of sulfate ions enhances the ionic strength of the medium, leading to the dissociation of cupric-chloro complexes. Looking into this study, I was struck by the complexity and nuance of the deformation process. The interplay between the different anions and the liquid metal is fun to watch, and it's clear that further research is needed to fully understand the underlying mechanisms. My look-in: - The study highlights the importance of considering the role of anions in the deformation process of liquid metals. This has significant implications for the design and optimization of soft machines and electronics. - The findings also underscore the need for further research into the properties and behavior of gallium-based liquid metals. As we continue to push the boundaries of materials science, it's good that we develop a deeper understanding of these materials. - Finally, I believe that this study demonstrates the power of interdisciplinary research. By combining materials science, chemistry, and physics, we can gain a deeper understanding of complex phenomena and develop innovative solutions to real-world problems.

Happy to introduce our latest work published in ACS Nano 🎉 In this work our research focuses on improving a technique called graphene-enhanced Raman scattering (GERS) for better optical sensing. GERS works by transferring charges between molecules and graphene. We found a way to precisely adjust this charge transfer by using atomically thin metal layer called as the two-dimensional (2D) metal. By tweaking the Fermi level of graphene, we enhanced the signal and selectivity of GERS, especially for molecules like copper phthalocyanine (CuPc). We used DFT calculations to understand the mechanism and validated it with other molecules like rhodamine 6G and crystal violet, showing promising results. Our study highlights the potential of using 2D metals to make GERS sensors more sensitive and accurate.
