Name :Low purity single-walled carbon nanotubes (long)


Product Overview

Carbon nanotubes, also known as buckytubes, can be viewed as seamless hollow circular tubes formed by winding a single layer of graphite hexagonal grid plane along chiral vectors, with carbon atoms typically capped at both ends in pentagons. Therefore, the carbon atoms in carbon nanotubes are mainly sp2 hybridized, and once the hexagonal network structure forms a spatial topology, a certain sp3 hybridization can be formed. The diameter of SWCNT is generally between 1-2 nm. Single walled carbon nanotubes can reach lengths of micrometers, even millimeters and centimeters, with a large aspect ratio and superior electrical, mechanical, and thermal properties.

Product Features

Excellent conductivity: It has excellent conductivity, high conductivity, low resistance, and can efficiently transmit current. For example, its conductivity can be comparable to excellent conductors such as silver and copper.

High thermal conductivity: It has excellent thermal conductivity and can quickly transfer heat. It has potential application value in electronic devices and thermal management systems that require efficient heat dissipation.

Unique mechanical properties: possessing high strength and toughness. The tensile strength can reach 100-200 GPa, and the Young's modulus can reach about 1 TPa, which makes them have great potential for enhancing the mechanical properties of composite materials.

Nanoscale effect: The diameter of the tube is generally around 1-2 nm, which has unique properties brought by small size. For example, due to quantum confinement and surface effects, they exhibit different characteristics from macroscopic materials in terms of interactions with other substances and electron transport.

High chemical stability: It has good stability in general chemical environments and is not easily reacted with acids, bases, oxidants, etc., which enables them to maintain stable performance in various complex application environments.

Diversified forms: Different forms such as bundles, films, and networks can be formed to meet different application needs.

Optical performance: It has absorption and scattering effects on specific wavelengths of light, and can emit light under certain conditions, which has potential applications in optoelectronic devices.

High flexibility: It can bend and fold without breaking, which has advantages in the manufacturing of flexible electronic devices.


Application Fields

In the field of electronics: Due to their unique electrical properties, single-walled carbon nanotubes can be used to manufacture smaller and more efficient integrated circuits, field-effect transistors, and flexible electronic devices.

In the field of energy, single-walled carbon nanotubes can be used as electrode materials in lithium-ion batteries, which can increase the battery's charge and discharge performance and cycle life; It can also be used to manufacture supercapacitors, improving the energy density and power density of capacitors.

Composite materials: Adding single-walled carbon nanotubes to polymers and other materials can significantly improve their strength, stiffness, and toughness.

Sensors: Utilizing their high sensitivity and selectivity towards gases and chemicals, they can be used to detect biomolecules and cells, among others.

Nanomachinery: Single walled carbon nanotubes can serve as key components for constructing micro machines, such as nanomotors.

Aerospace: Used for manufacturing lighter and stronger aircraft and spacecraft components.

Other fields: It also has applications in catalysts, field emitters, conductive films, and biological nanomaterials.

Solidly constructed and has a premium, hefty weight
Size: 58.5mm
Works exactly as described. Can be a bit heavy but otherwise it is a premium built product. If you have too much coffee in your basket and they're near the rim of it, coffee can get stuck to the sides of the distributor. A little annoying but easily remedied by brushing the grounds back into the basket or by "flattening" the coffee grounds in the basket first prior to distributing.

Would purchase again
Size: 58.5mm Flat Base
Fits my Gemilai portafilter perfectly. Works as expected, but can be slightly unlevel in tamping. Has a tendency to push the coffee down more on the handle side of the basket. I try to make sure I apply pressure in the middle of the tamper and it seems to make all the difference.

used product, but works
Size: 58.5mm, Size: 58.5mm
The product is good, I was sent a was clearly looks to be a used product with scuffs on it and some rust, I can clean that up and for what it does, it'll do, just weird to receive a used product.

Great scale that needs some improvements to be perfect
Color: White, Color: White
Very accurate scale, looks good in white, timer works nicely and I do like the concept of the ratio conversion. Shown in photos with 0 measurement drift over time, even without the silicone mat. To make this the best scale in the price range, I would change: - The auto timer function. Timing currently stops if you pick up the brew to swirl; you must completely restart the process if you do happen to pick it up. I would change that to only stop on user input (pressing a button). - The ratio conversion. Why offer XX.0 precision if you can only change the ratio in whole amounts? I'd suggest offering 0.1 increments, selectable with +/- buttons instead of cycling through. - The silicone mat is not well affixed and slides around. Kind of useless as-is and I just keep it off. I would wrap the whole thing around the measurement platform, similar to how the Greater Goods scale does it, to really keep it secure. It's not perfect, but for the price, it's a 4.5/5 for me. Rounding up to 5 since a 4 is considered "bad" by today's online rating standards.

IMO, a filter coffee lovers best scale option on a budget. Solid grade A choice.
Color: Black
I have two other .1mg "coffee" or food scales that I used regular for pour overs. I saw this has 4x display on real time flow rate, g/mg weight, timer, and grounds to water ratio for a solid price and purchased this after reading some reviews. One of my scales has these features, but the workflow on this scale just clicked a ton better for me. The beep isn't super loud annoying which is a major relief, as I just couldn't keep sound on on my other scale due to that trigger honestly. I tried brew mode immediately and will now only use that when making a pour over. Loved the beep alerting when I finally hit the proper ratio and I like it keeps my final info on screen after the brew for my study. I can actually practice my technique now and not have split attention as much. This is still compact, but fits a larger carafe well whereas my other scale is a better fit for the espresso machine. The display is clear and buttons have a slight tactile sensation from the print, but are still the capacitive touch based style. I tested it with weights and it is my most accurate scale, it hit the .1g accurately every time or at worst would fluctuate back and forth quickly from the true value (more than enough for me to trust it). It updates and tares from power on fairly fast, it reacts fast enough to touch to not make me pause much. My nitpicks are that the front clear matte plastic isn't quite uniform flat viewed at an off angle giving it a cheaper look, but that doesn't affect functionality at all and truth is, it really was very affordable for the feature set I feel. The second nitpick was that the scale's mat does not grip well or fit securely over prompting it to move around easily. For this I had to modify using some rubberized grip tape on the surface of scale underneath the mat itself. Now it doesn't slide from vibration and if any pressure down it doesn't slip. I could have removed it totally, but it is attractive and useful once stabilized. With that modification done, I can fully recommend this scale for filter coffee lovers at any price. Great product, hopefully lasts me a long time.
