Electrospinning Machine 30kV | Demonstration
มุมมอง 28Kปีที่แล้ว
@sprucescience You can use the Electrospinning Machine 30kV to make ultra small diameter fibers. You take the polymer solution and use a syringe pump to deliver it to the needle tip where high voltage is applied. Under the intense electric field, polymer fibers are charged and stretched while it travels through the air to the rotating collector. With an apparatus like this, you can conduct a lo...

Sausage making with a vacuum mixer
มุมมอง 4322 ปีที่แล้ว
#sausage #food #foodscience Making home made sausages with the Spruce Science vacuum mixer was exciting. Beef loin New York steak meat was used to make the sausages and the seasoning was mixed using the vacuum mixer. By mixing under vacuum, the seasoning is able to penetrate deeper into the meat for a richer flavor. Because the mixing was in an environment that is free of air, you are able to p...
NeoDen4 Pick and Place Machine Crashes | Part 2
มุมมอง 6272 ปีที่แล้ว
The NeoDen4 pick and place machine crashed because the controlling software failed to move the nozzle up to clearance height. You will see the nozzle slam into the rail feeder twice. After the first crash, the software attempts to move the head again without addressing the underling problem. I pressed the emergency pause button on the machine or else it would keep slamming into the rail. If any...
Motion Sequence Error on NeoDen4 Pick and Place Machine
มุมมอง 1.1K2 ปีที่แล้ว
The NeoDen4 machine software seems broken. Under normal conditions, the nozzle goes down in z depth to pick up part from feeder or place it on the PCB. It then moves back up to the clearance height before proceeding so that it doesn't crash into other things. However, this machine doesn't operate properly and the video captures moments when the machine moves with the nozzle in down position cau...

when you are doing this, how are the fibers forming a sheet or layer without sticking to the bottom layer like if it was a fabric roll? or does it dry up really fast?
I really like this, thanks
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
can you spray glycerol droplets? They will not evaporate and will be easy to clean
Still using the machine? Root cause found? Gave up?
I have a Neoden 3V. It is a buggy machine. Without reason it will corrupt file that was working perfect and make a mess .. That machine is a waste in of time and money
great explanation Electrospraying+ion trap
Amazing! Thanks for sharing.
Was the needle charged at 6kv positive and the grounding plate 30kv negative?
When we making nano coating using PVP as a polymer binder, does it Dissolve after preparing a coating?
Can i construct a high voltage source setup at laboratary
Can you please make a video on Antimony Tin Oxide Oriented Nanofibers using electro spinning method?

EXCELLENT VIDEOO!!!
If you spin horizontally instead of vertically you will not get splatter and drips.
Could this process be applied in an anoxic environment to metal alloys?
Can dripping be avoided by turning the setup upside down?
What is the cost of the power supply?
Amazing bro! it is incredible!! thanks for sharing!
What DC motor did you use to push the syringe? I assume you'd want something that can run pretty slowly
Looks like a dc motor with integrated reduction gear. A worm gear should give you plenty of torque and slow continuous rotation.
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!
It is very unusual to make device first and then think about how to apply it to real-world tasks. Such approach is risky, but I like it for some reason. I hope that your device will make our world better eventually.
why viscosity should be low when we use water as a solvent for pvp
does this work with charcoal? I want to electrospin charcoal fibres to make carbon mats
This video experience was almost fun, ymmv.
Ok bro
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.
Hah, the dramatic music and narration had me on the edge of my seat the whole time!

Hi we have same problems , how we can solve that?
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?
@@sprucescience We had defined two nozzles in the pcb information section, but in the feeder setting section of the aply section, 3 nozzles were ticked, and we apparently solved the problem by removing the extra nozzle.
@@sprucescience We are also having this problem recently where we are having a problem with the "photograph is faild" box, do you have a solution for that?
@@ibrahimmousaviHello İbrahim, I am getting the "photograph failed" error, how did you solve it?
@@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.
Great way to make a small micron filter for cheap?

Thank you for expressing interest in our product. We're always excited to hear about the projects and endeavors our customers are working on. Would you mind sharing a bit more about what you are working on? We'd love to see how our product might be able to support your efforts.
How much? Just filled out your website contact form.
w.tf is this? and what are the uses
It literally tells you if you watch the video.
That's worrying. Is this a new machine or an existing one? Performed any firmware or software updates that may have caused it? Have you reached out to Neoden?
Yes, it is concerning. This machine is new and we were told that the software is the latest and up-to-date. We found a feeder that was not responding so it was unplugged. Removing it seems to by pass the error but we not sure what is wrong with the feeder or software.
@@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.
