Hi, great video! I noticed that you mentioned mixing 0.431 g of PVP with 0.569 g of ethanol. Considering the solubility of PVP, especially with a high molecular weight, wouldn't this result in a very viscous solution or possibly incomplete dissolution? Could you clarify if you used any specific conditions, like heating or prolonged stirring, to achieve this mixture? Thanks!

Can you make Antimoney Tin Oxide Nanofibes using Electrospun and the polymer should be PVP ( Mw =360kW). ALSO What if use different Mw of PVP?

I tried electrospraying starch in alcohol. It charged my quartz glass enclosure electrostatically and nothing could be trapped at all. Needle produces ion eind which blows away everything. I like your setup with metal surounding the trap to prevent from charging up. Will continue to tweak my setup

@tt7762 Жыл бұрын
Very clear demonstration But why you didn't mix the two solutions in one syringe from the first step? Why use separate syringes and then use coaxial spinneret if what I desire is mixing them into one nanofiber at the end?? What difference would it make? And if so could you please design an experiment please? Electrospinning is my thesis subject!

How about mounting the spray need assembly inside a large torus/short cylinder, and spinning that around the collector? Direct application of the fibers to an unmoving wound would be possible. A cheap(ish) testbed could be made from a toroid core transformer winding machine, perhaps.

We tested each feeder and peeler individually by manually advancing them several times under the "Manual Test" tab with the "Feed Peel Synchronous" box unchecked. During the test, we discovered that one of the feeders was not responding. We unplugged the malfunctioning feeder and noticed that the feed-box feed error disappeared. After removing the problematic feeder, we retested all the feeders with the "Feed Peel Synchronous" box checked and found that they were functioning properly without any errors. We tested multiple times on each feeder and did not encounter any issues. It seems that the malfunctioning feeder was causing severe problems and causing the software to hang. Removing it appears to have resolved the issue, but we are unsure of the cause of the problem, whether it is with the feeder itself or the software. What are you currently working on?

@@lovesick3933 Hello, I have a 3V-Adv and that error (Photograph error) appeared when the cables of the camera (USB) where loose so the computer doesn't recognize it anymore. Additionally, random miss placing error where produced because of a faulty connector on the stepper motor that rotates the nozzle. In summary: Whe soldered the cables directly to the cammera (down looking), changed the USB port of the uplooking camera (inside the machine), replaced the faulty connector on the stepper motor. I know its a little bit older the question, but I believe someone will found it useful.

@@sprucescience Very odd fix. Picked up one new recently, it works but it's a bit disappointing for the price for a 6 year old machine, a bit slow, one camera, x/y misalignment (a few mm out over 200mm). I wouldn't buy a Neoden if I could avoid it. You can buy a higher precision machine (but weighs 200-300kg) for the same price. Some people have modded their Neoden to use OpenPNP but it's quite the time investment

Although its been a year now .. but i still wuld suggest to chk ur pick n place file. The Software developer are not good to chk long names and buffer over flows .. So long names of components in pnp file cause such probs on some pnp machines. U can manage ur cad software to produce shorter names or just do tht manually in xls sheet before loading to pnp machine.
