In this study, graphene oxide was electrochemically deposited and reduced on a graphite sheet. The electrode surface morphology was studied by scanning electron microscopy. The performance of the modified electrode in detecting dopamine was investigated. The results indicate that the electrodeposition of reduced graphene oxide onto the electrode surface increases the dopamine oxidation current, decreases the overpotential, and reduces the charge transfer resistance. The efficiency of dopamine detection ...

Any nanotechnologist here, I need to ask a few questions relating to application of nanoparticles on insects. I am very new to this field and have zero exposure to it, I know the method to synthesize nanoparticles but don't know how to apply them. Preffered nanoparticles are siilver, silica and zinc. My questions are;

1. After synthesis , is it necessary to centrifuge the obtained stock solution or the solution can be applied directly.
2. If centrifugation is necessary, how to make different concentrations of nanoparticles in water. (Any other solvent, please suggest).
3. What is the best method of application of nanoparticles on insects?

Thanks (any help will be appreciated).

Hi , If anyone here knows about AFM and would tell me the significance of steps for data analysing in AFM , I would really appreciate. I am a student and have been assigned a project based on AFM. Now when I do the tests , I am asked to do calibration of tip and rest of the stuff . I am also asked to check Pull of curves for adhesion etc . I just get average friction and set point from the device and am to convert them to friction forces in N. I Dont understand the significant of knowing various spring constants . Why do we calibrate lateral forces and why do we need pull off tests. What do these actually mean .

Any help would be helpful.

I am interested in hearing how experimentalists in the field get theoretical data to support their experimental work? And what struggles do you experience in the process?

Lg channels take minimum 1 minutes to load? Also changing channels is slow , 5-20sec! Even toggling one channel up or down. Or previous channel toggling. Video quality and refresh is great once channel loads. This happens after several software, firmware updates. This happens when wired or wireless network connections. All other network are working properly speed. Not a local network issue.

Hello there,

I've launched my first open-source project, NanoRender! 🌟 NanoRender is a Python package for generating 3D models of atomic systems (molecules, materials etc). The code generates a HTML file that showcases the model, which can be used independently or added to a website.

The code is literally in its infancy, barely a hundred lines long, but I am excited to see how it will grow as an open-source project.

Collaborations, contributions and comments are all welcome! Join me as we revolutionize scientific visualization with Nanorender. 🌍💻🔬

Hi, I am a freshman at The University of Warsaw, studying nanoengineering. I am very intrested in the subject and am seeking book recommendations to learn more about the subject, outside of my courses in Uni. Can anyone here recommend some? Thanks in advance!

I am making a review about liposomes and I found out some papers about niosomes. Can I just ignore the different names and go ahead?

Hello,

I want to learn about the topics listed in the title. I'm an EE student and have some knowledge in electromagnetics and nanoelectronics. If someone could help me by giving me some literature where i could study about these topics i would greatly appreciate it.

Earth's magnetic field was always interesting to me and when one of my teachers mentioned that they measure its intensity to determine ores in the Earths crust it was fascinating to me. And looking into it i saw that the largest silver deposit was discovered using a SQID magnetometer.

I would really like to learn what phenomenon Josephson effect describes and the math behind it and also how that is used to measure magnetic field with great accuracy.

Any help would be appreciated.

I made the decision to buy an evo nano + at 2 am and ordered from autopilot.com... how screwed am I? Are these guys legit? Had anyone here had good or bad experiences with them?
