Name:a>CMK-3


Product Overview

 

CMK-3 is usually prepared by nano casting using ordered mesoporous silica material SBA-15 as a template. The English name is Ordered Mesoporous Carbon Material CMK-3, and its specific preparation process is roughly as follows: carbon source precursors (such as sucrose, phenolic resin, etc.) are filled into the pores of SBA-15, and under certain conditions, the precursor is transformed into a polymer. After high-temperature hydrolysis treatment, the SBA-15 template is removed to obtain CMK-3 mesoporous carbon material with the opposite topology structure to SBA-15.


Technical Parameter

 

Average Length:μm

Purity:8at.%

BET ≥:800 m2/g

Vtotal:.0-1.5 cm3/g

Pore Size:-7 nm

 

Product Features

 

Good ordered mesopore structure: the arrangement of pores is highly regular. 

High specific surface area: usually the specific surface area is more than 500m2/g, which is conducive to increase the contact area with the reactants.

Good thermal and chemical stability: after optimised synthesis conditions or post-treatment, the ordered mesoporous carbon can have good thermal and chemical stability, and is not easy to be corroded or oxidised.


Application Fields

 

 

Catalyst carrier: Its high specific surface area and adjustable pore size make it an ideal catalyst carrier, which can improve the dispersion and catalytic efficiency of the catalyst. 

Capacitor electrode: In the field of electrochemistry, ordered mesoporous carbon CMK-3 can be used as an electrode material for supercapacitors, providing high energy density and long cycle life. 

Drug loading: Its porous structure can be used to load drug molecules, achieving controlled release and targeted delivery of drugs. Nanoreactor: In the field of nanotechnology, ordered mesoporous carbon CMK-3 can serve as a carrier for nanoreactors, promoting chemical reactions.

 Large molecule adsorption: Its high specific surface area and pore structure make it potentially applicable in the field of large molecule adsorption. 

Biosensors: Ordered mesoporous carbon CMK-3 can also be used for the construction of biosensors to improve their sensitivity and selectivity. 

Energy and hydrogen storage carriers: In the energy field, ordered mesoporous carbon CMK-3 can be used as a carrier for energy and hydrogen storage materials to improve energy storage efficiency and hydrogen storage capacity.

Great watch, flimsy band
Color: Gray/Lilac
I bought this watch to replace a similar model because the band broke. I see this is a recurrent problem in many other reviews. However, I liked the watch enough to buy it again anyway. I found the new model easy to set, being fairly intuitive. So far it keeps perfect time. I use this watch mainly as a travel watch, and loved the dual time zone function. I am pleased that the newer model now has the ability to set 3 times zones instead of 2, which is an added bonus. The only con I see at this point is the flimsy strap. Unfortunately, the strap on this model is even thinner than on the previous one, and I wonder how long it will last. Also I wonder about the battery length. I think these watches may have been sitting around a long time. The setting showed 2012. I am afraid much of the battery life of the original battery may have already been used up and the battery may need replacing early. Only time will tell. The watch fits my small wrist fine and it is a little more attractive than the old model. I give it 4 stars instead of 5 only because of the band problem.

Great fit and quality!
Color: Black/Gray
Always love the quality of a Timex watch. Great fit for smaller wrists.

Fine for a man (with skinny wrists)
Color: Black/Gray, Color: Black/Gray
I have an older mens ironman which has gotten a little beat up and needs replacing. The band is much longer than I need. The metal clasp sits off-center on the underside of my wrist, closer to the part of my wrist which curves around to the front. The too-long strap sometimes flops around and catches on things. I couldn't find a smaller-band mens version, so I tried this "womens" watch (picking the most manly-looking one, of course). I like it better. The band fits my wrist much better, with the metal band in the middle and no flop. I also like that the watch is lighter and the face and band are smaller and less bulky, so it is less noticeable when I'm wearing it (cycling weight weenies will appreciate this). The face is still large enough to be easily legible and contains all of the same great features as my mens ironman watch, plus the newer versions now have an hourly chime, nice! Other info: my wrist is ~17.5cm or ~7.0" around. On this watch, I use the 6th out of 9 slots on the band. On my mens ironman, I use the 3rd out of 9 slots. Weight: this one = 28g, mens = 39g. Pics show comparison of my prior mens ironman with this new "womens" ironman. Photo order is confusing (couldn't figure out how to change that). They are: (1) side-by-side, mens on left, (2) mens band (wider and clasp is off-center on my wrist, end of band hangs over the edge of my wrist -- too long for me -- catches on things), (3) womens band (less wide, clasp is more centered on my wrist and end does hang over edge of my wrist), (3) womens watch (smaller, and looks new), and (5) mens watch, looking a little beat up.

Watch holds up in saltwater!
Color: Black/Gray
I bought this watch to use for my trip to the Galapagos Islands. I read two reviews that the watch does not hold up in salt water. I went snorkeling in the ocean 6 times, about 45 minutes each time. The watch did not leak. I did take precautions by keeping the watch under my rash guard and lowering myself slowly into the water. I also rinsed off my watch each time I snorkeled. I also bought this watch for the multi time zone feature by saving the time on the west coast, east coast and Galapagos time since I cannot change the time on my Fitbit until I land in an airport. I did not use any other features of the watch because I generally use my phone or Fitbit for an alarm or timer. The only complaint I have is that Timex now discourages changing the battery by the consumer. I changed the battery myself on my old Ironman watch. The new Ironman watch is fitted with triangular head screws. So I will have to purchase screwdrivers with triangular heads when it comes time to change the battery.

Reliable and durable, even in harsh conditions
Color: Black/Gray
This watch has served me very well. From Arctic waters to long distance races, it has held up to everything except one task I asked of it, which was my fault. This watch can handle repeated free dives to 12 ft deep. It cannot handle scuba diving at the same depth for an hour straight without needing to have the battery shorted to reset it. It fits well, lights up consistently and brightly enough to read without being blinding, keeps accurate time, and generally does everything I want it to.
