I was just interested to see if you were using toothpaste cuz you had toothpaste sitting on your counter last time and if so maybe the active ingredient of peppermint is what's giving you the ability to make this work.
I'm glad you were showing this video without any secrecy. You say water is the most thermally conductive of liquids but what about gasoline... gasoline is kind of like peppermint oil maybe it's not the purpose to find something that's naturally cooler maybe these liquids don't conduct thermally as well... Either way super fun video thanks 💯
I was fortunate enough to have someone of similar ability to clearly explain for chemistry one year. He was considered a bit of a "hottie" by the girls too, so that kept them quietly shy so we could learn, which no doubt helped.
I’ve always loved your videos. You’ve genuinely helped me think, scientifically, about everything around me. I’m listening to this video on my own DML speakers that have phenomenal performance for pennies. And the best part about them is that I know exactly how they were made and how they can be improved upon. Please don’t let anyone or anything stop you. You are helping my children learn how to think and process and create the world around them for the better.
Спасибо большое, что делитесь информацией и даже помогаете советами, хотя, по сути, это продукт ваших трудов, интеллектуальных терзаний и огромного количества потраченного времени. Я поражён вашим умением объяснять технически сложные термины даже для такого человека как я, я не очень хорошо знаю английский и изучал язык по сериалам и кино. В общем, удивительно, что вы распространяете полученные знания, за это вам моё уважение!
You are absolutely the best expository teacher I've ever encountered. I believe that Prof. Richard Feynman would highly approve of your style. Bravo on your most excellent work. How I wish I had had such teachers when I was in school. Perhaps I would not have been so thoroughly bored with school by the time I graduated.
@@TechIngredients My opinion is based on my years in the field of Chemistry, polymer science and Material science. Your channel clearly is a upgrade on presentations of complex topics and you nail each one of these topics with more than one would expect. You have my attention and that takes effort to keep me listening these days. Well done!!
How is this channel so consistently amazing? There are SO MANY well researched, well produced, and entertaining videos on so many interesting and diverse topics. On top of that, the regularity and frequency of uploads is insane for the quality of content. Can't believe all this is made available for free without the typical and pervasive sponsor spots for xyz vpn. Keep up the incredible work Tech Ingredients!
Thanks for the rerun of basic school physics. Also you answered questions just as i was asking them myself which really impressed me. After the basics you went on with doing stuff, skipping boring parts and showing almost everything interesting. I'd have loved to see a vacuum timelapse of escaping air (or maybe nothing to see but i'd like to see myself). Only thing i dislike nowadays are the "please subscribe" messages. I think channels should get subscriptions because they earned it and not because they asked for them.
Thanks. It's the uncomfortable part of running a channel, but as I said, without a large footprint we don't get the interest of businesses or institutions for tours, interviews or collaborations.
For the last incorporation step, would you consider using paint mulling techniques? The equipment is relatively low cost and the technique is specifically designed for incorporating fine powders very evenly into a liquid. Usually the pigments are on the order of 0.05-several micron, depending on the exact pigment, and of course the liquid is linseed oil, so I think the technique is potentially applicable to this situation. I think it' s worth trying; it would certainly be faster and more effective than the mortar.
that's a very good question that I do not know the answer to, doesn't look to be that different from the mortar and pestle. I imagine major manufacturers must have some method to mix up large quantities of the stuff that is cost effective. I think the biggest concern is 'folding' air into a thick mix of something that air is not easily deaerated from. Hmmm.
I've come across your channel after the LTT video, and I'm very impressed ! Really appeals to my physics education in the presentation and explanations. Subscribed!
You guys are hands down one of the best channels on RU-vid (if not the best). Really great content and I really appreciate the way you take time to explain the principles and do a very thorough explanation on the subject, so that even people with no background can understand why this works the way it does. Anxiously waiting for the guys from LTT to test your findings :)
WAIT! You’re about to do Ultra High Performance Concrete???? I’m working on a Rammed Earth “3D printer” that will automate the tamping process. I’ve been looking at Dr. Tyler Ley’s research that he posts on RU-vid about modern concrete, as well as other additives like India’s LC3 initiative to increase the performance of Modern Rammed Earth into the UHPC ranges. I would absolutely LOVE to see all the details on what you’re doing with UHPC and how it could apply to the Rammed Earth space. It will genuinely impact the world. Thank you so much for all the work you do.
Cheap, smaller sized drill presses from Harbor Freight make great mixing machines! And, with a little ingenuity, you may also be able to rig up a rather stout attachment to use as a centrifuge.
Great video, liked your sound in material explanation. Please make a working "was scepter", the Egyptian staff that was supposedly just ornamental, but in fact it was probably a sonic tool, it was a tuning fork in one end, a long rod and another shape in the other end, if the tuning fork vibration is same as the second harmonic of the longitudinal vibration of the rod it could be held by the middle with one hand (by the node of the second harmonic) and since the tuning fork shape redirects the prongs vibrations to the rod as longitudinal waves the energy could be used in the other end without slowing down the prongs vibration, so it would be a 8-10 seconds of free work in the other end of the rod while the tuning fork is vibrating.
Could you possibly do a segment with peltier heat pumps. I find them fascinating and I'm certain you could really broaden the conceptual application of these devices with your approach and insight .
Great video! I won't be doing this any time soon, but very interesting nonetheless! Came over from Linus Tech after watching their review on it, amazing job! Yes, please send some of this to Gamer's Nexus as well, as they have all the equipment to do further testing of your paste. You get credit from the crew over there and you'll most likely sky-rocket in sales, especially seeing you're an independent and not a large company =)
Definitely going to try at least the simple version and compare with what I use now. Also I would love to see a video about the high performance concrete speakers you made they look awesome.
hi I don't know if you have tough of it or if someone else has suggested it but instead of the Mortar & Pestles you could use a wet grinder there relatively inexpensive and are made to grind thick past for long period of time like for making chocolate
Best scientific channel on RU-vid. GREAT teacher, although I still don't know what his first name is. Whoever you are, just excellent work. Thanks Dude!
A very interesting video. Especially the proportions and the sizes of the powder particles. Congrats on the discovery. Also, a nicely done presentation. The effort is appreciated. :) Cheers! :)
I came across this video, absolutely fell in love with your teaching skills, and wanted to subscribe but.. there was an issue. I'm already subscribed haha!
I want to see the second rod cut also - at the same point - and a sheet of aluminium as thick as the plastic one in between, to see what difference the surface layers make. ..Compared to no surface layers in the second rod..
I once watched a video about LED bulbs/lights and how ,for planned obsolescence, the factory used too little thermal paste. The person went on to say that he would disassemble each LED he bought to remedy this by replacing the old paste. Saying that they would now last "forever" or a long time. Is there any simpler paste we can make at home that would suit such a need? Thank you for the great content and inspiration
You are mislead if you think that is the main/only issue with the life of commercial LED bulbs. Most of them don't have any thermal paste, cannot be disassembled to add any, and will not benefit from doing so. Compromises of the design on manufacture of LED lamps are not for "planned obsolescence", it's simply to reduce manufacturing cost.
The 2 questions I have are 1- what is the electrical conductivity? 2- what considerations are needed or I guess were taken into account for galvanic reactions? Otherwise very interesting. I get criticized for building a "lab" in my basement for brewing but I don't even have an ultrasonic horn, I do have an ultrasonic bath but that's as ritzy as I get... For now.
Jeez, his first 5 minutes would take a regular teacher one week to explain. Good stuff. People, this is MIT level teaching. I like watching his channel because I always go, "Oh yeah I remember that." Its like I re-remembering info. But children really should also watch (it is the best education). For future parents: You gotta find packs of teachers who roam these streets and live that lifestyle. The teachers all know each other and they hire like minded friends and individuals with similar attitudes and education practices. I just lucked up and took AP classes. They are located in the AP classes. Good teachers do not like teaching knuckle heads. I had one AP physics teacher, one AP chemistry teacher, and one AP female math teacher in high school. They also hung out with the history teacher too (but I never took AP history). They were friends and also gigged as college professors. They introduced alot of info in the same manner which probably made me unnaturally smart due to their exposure of correct science methods and mnemonics and correlative thinking. My brain was bored at school until AP physics and AP chemistry. I would read the books during class and finish the homework during class and only ask questions when I did not comprehend the book. It allowed me to go to sleep after athletic sport practices when I got home. Good memories. It also let me know that my brain was not normal. I had another athlete student in the AP classes with me. Most of the AP students were not athletes. I would tell him my test scores and it become a competition. We would discuss why he and I got wrong answers. We always had As and Bs but could care less because we had a big game coming up and needed to workout and sleep. But it suprised the h311 out of all our teachers when we got highest 5's on the end of year AP credit tests. We were racking up college credits. We did not get the high semester test scores but he and I would always score the highest college credit scores or end of the year. Today he's my dentist. When I went to college, I already knew all the education and I almost skipped freshman year due to credits. My high school education was better than my college education. So what I am saying is that I know good teachers. This guy is one of the greats. When I was like ~30, I was interested in why I had so many good AP teachers at one high school. So I went back to my music and chorus teacher and he gave me the low down on everything. All those teachers were college classmates and ex-athletes. The Principal was the main guy and athlete. He hired all of them. And they still work together at a different high school. They go from school to school changing the curriculum and making the district better. They all liked each other so much, that they decided to always work together. I let them all know they made a huge difference to alot of us students and my sibling and cousins too. There are good teachers still doing their thing. But I do recognize that my high education was better than my college and post college educations. My AP classes were so chill. We could negotiate the number of problems for homework if we convinced them that we got what they were trying to teach. And we long term learned it. I am still friends with alot of my peers from high school and college (and church). But it blew my mind that like 12 of the teachers there were all smart friends. It made sense once I looked over it. The AP classes would have casual parties during school hours with the other AP classes. We had to apply what we learned to real world problems. These guys ran under the radar too. They did not want medals and accolades. Man, all of my gym teachers and coaches were once NFL, NBA, and minor league players. My AP math teacher was a swimmer who was the wife of an olympian swimmer. Very rare area. After I gathered info, I thought it was some type of secret campaign or something. But nah, they were just cool like that. P.S. If you read through all that, I never took AP English but I probably should have. I saw English as a waste of time that I replaced with computer programming. I found out she was also a friend of the pack. I also learned that they owned patents under|with boeing and ibm and other companies in the area. Which explains why some of them were so well off. I think they were doing the high school gig just for fun and to pass the time. But I do recognize guys that know what they are doing. This guy is good.
This is absolutely incredible! My only concern is the mixing of copper and aluminum, as its a common concern when it comes to corrosion. Some heat sinks use a copper transfer plate. Would the aluminum paste cause corrosion with a copper transfer plate, or does the glycerin insulate it enough to not cause any corrosion?
Fascinating as always. I always learn a lot when I watch your videos. I'm curious to see what LTT and others come back with as far as results. Great and thorough presentation!
Idea for another video: aluminium air batteries. I came across them some weeks ago and you handling the aluminium powder brought back the idea of them. The principle sounds simple and I ask if it would be possible to create one. The more pressing question is: what would be necessary to "recharge" / refurbish them? Don't we just have to scrape off the oxygen and it works again? Do we really have to melt them down? Hope that's an interesting enough area to investigate. Loooooove the stuff you make. Thought about building a speaker myself.
Ok this might be a bit too crazy of an idea but how about synthesizing Boron Arsenid as use for the powder? Maybe synthesis is a lot easier because you don't need big crystals. It would obviously be absolutely impracticle but interesting nonetheless.
Does your thermal paste shear-thicken much? Demolition Ranch recently tested the ballistic properties of non-newtonian fluids, but only using aqueous corn starch "oobleck". The most recent research papers I could find on non-newtonian fluid armor used silica nanoparticles and kevlar fibers. That could make an interesting video collaboration.
The glycerin version does have a narrow range of mixing where thickening occurs. Almost all non-newtonian fluids have a range beyond which (below AND above) they operate as Newtonian fluids. That is the problem with thinking that materials like oobleck do not work well as ballistic barriers.
@@TechIngredients I'd be curious to test that in the orders of magnitude higher range for ballistic impacts. Even if the effects don't turn out to be unique, the collaboration with Demolition Ranch would be good.
Tech Ingredients please make more of rocket videos. I have watched all of them and was sincerely waiting for you to experiment further in hybrid rocket engines or maybe assemble it to static test a 1 stage rocket?
What about a tilt stone wet grinder for the final step. You have to make larger batches but if you are actually selling this as a main product you'd probably want to make larger batches. Because there's small ones for doing small batches of chocolate they're only a couple hundred bucks.
@@TechIngredients That would be awesome. Also Gallium liquid cooled v water cooled loop and any corrosion or other issues with using Gallium. I think Gallium can dry or solidify like glue as it's somewhat open to air and with months of heating and cooling cycles and leaves some kind of pitting on the metal surfaces, as I saw a little last time I took off the huge Macho 2 Bravo heatsink with its nickel plated copper plate, from 9900k cpu copper IHS and another from gpu EVGA 1080TI Kingpin with just copper plate (gpu silicon die wasn't pitted and perfect mirror looking). That's over 2 years ago to experiment with fresh application and clean all dust out versus 1 or 2 years old application with same pc overclocking settings. So I mirror polished the metal surfaces, reapplied gallium TIM on both sides whilst careful to not get it on the tiny capacitors nearby by covering them with tape just whilst applying. It is still working great and cool. I want to experiment again with fresh polish and application of Gallium based TIM. I've just googled Gallium thermal conductivity at 29 W/(m K) compared to almost 400 for copper and just 0.6 for water
great stuff! i cant imagine taking the time to create and test all these formulations including the nearly 1hr worth of processing required for each iteration. thank you. I'd like to see your thoughts on a chilled water setup using a cheap tec and temperature sensor to create an ambient temperature loop. I feel that this would make an efficient cooling product suitable for 24/7 operation and eliminate condensation. perfect for intermittent type loads normal for most gamers or small processes etc. the electronic control portion could even be marketable....
I suggest why in our later video on graphene. In addition, its extremely large surface area prevents you from adding enough of it to be competitively conductive.
@@TechIngredients And it raises another question about utilizing "copper powder" copper has much more thermal conductivity in comparison to aluminium, why you (and many commercial products on market) don't use copper instead of aluminium???? It is very big question!!!!
Now the next step gets a bit tricky. The liquid is to viscous for the morter and pestle. What you need to do is put it in an old fashion butter churner. Then you need to mix it for an honest 16-32 hours. Oh when will it end in mixing hell!!!!!
How much would the "adequate" paste improve through continued mixing, followed by vacuum degassing - possibly using a vibrating plate of ultrasonic emitter to aid in the outgassing. Would a moderate level of pre heat of the material increase the efficiency of the vacuum degassing?
Im confused, was that you using EEG heterodyning? So was it you who suggests me on how to hack into their systems? I thought it was my own idea, as if someone told me
gave this experiment yet another try using different mortar and pestels since I assumed the shape to be an issue making the glycerin stick to korners I wouldn\t rech but I just haven\t been able to replicate it mostly it felt like the issue was no enough glycerin so when I went up the g for that ingredient it started to look somehow similiar to your at around 9 grams but it never performed as well I guess I am just doing something wrong that I am unaware to notice
Given that you are stuck with that powder and have to hope that in fact that it is spherical, the key is to reduce the glycerin fraction. Try blending it at an elevated temperature. Don't heat it so much that you can't touch it, otherwise when it cools it will become too viscous to work with, but it can facilitate the blending process.
I can't see it being cost effective to make it on your own. Take the cost of all the materials and take away the percentage of the materials you actually use to make the amount of paste you need. I imagine it'll work out at $30-$40 for the application and you'll have loads of material left over sat there doing nothing. Meanwhile you can buy thermal paste for about $5. It would only make sense IF you have all the materials AND all the equipment to hand. And even then, you'd need to work in a computer shop where you spend a lot of time redoing CPU installs to make it worth while. Still, it is very interesting from a purely academic stand point. Thanks for taking the time to show us. :)
When substituting the 300nm al power for cu powder, would you also substitute the 5 micron al powder for cu instead as well to avoid the galvanic corrosive effects between the al and cu? Short term, no noticeable effects would be seen using both in the compound, but theoretically overtime the performance would degrade as corrosion built up. Also, with the same reasoning, would you only use the cu compound on cu heatsinks and the al with al heatsinks? I believe the IHS on cpu is galvanized, so the effect is lessened, but most al heatsinks are not galvanized nor a good number of cu heatsinks either. For the heatsinks that are galvanized, if you decided to do a few lapping passes to further increase thermal conduction, you would be removing the coating and essentially destroying any benefits from the galvanization process. (Yes it is odd that you use galvanization to prevent galvanic corrosion)
@@TechIngredients Zinc is the first that came up in a quick google search, but I think for computers Nickel is the coating of choice yes. The compound may be non conductive as a whole, but on the micro scale wouldn't some particles still make contact and gradually spread the reaction as it displaces more particles?
@@TechIngredients hey, on a serious note, may I suggest an episode. I have obnoxious neighbors that blast their music from outdoor speakers mounted around their poolside, they do this because they have money and no consideration. The property fence line is 70 feet from my kitchen side door, reading on average around 75 - 80 dba, from my door. Could you develop an episode on the best way to soundproof outdoors. E.g Materials, Plants, Phase Cancellation, LRAD 😄 Also, in consideration to 6 ft. height limit on fencing; weather; durability, and visual appeal. Thanks for your hardwork
Would it be possible to mix the high performance thermal paste less laboriously by including a volatile solvent that then evaporates away after the mixing is completed?
