Name: Hollow mesoporous Fe3O4 nanoparticles

Product Overview

 

Hollow mesoporous Fe3O4 nanoparticles are a kind of nanomaterial with a special structure. It combines the characteristics of hollow structure and mesopores (mesoporosity refers to pores with a diameter between 2-50 nanometers). It is mainly composed of Fe3O4. Composed of iron (Fe3O4), its center is hollow. This structure can increase the specific surface area of the material, while reducing its weight and improving its application efficiency in fields such as catalysis and drug delivery.

Technical Parameter

Appearance:Black colloidal dispersion

Diameter:180-250 nm(TEM:/span>

Product Features

 

High specific surface area: The hollow mesoporous structure provides it with a high specific surface area, which is beneficial to improving catalytic activity and reaction efficiency.

Hollow structure: This structure not only reduces the weight of the material, but also increases its porosity, helping to improve the adsorption capacity of substances and its efficiency as a drug delivery system.

Magnetic properties: Fe3O4 nanoparticles are superparamagnetic and can be rapidly magnetized and demagnetized under the action of an external magnetic field without hysteresis. They are suitable for magnetic resonance imaging (MRI), magnetic hyperthermia therapy (MHT) and drug delivery.

Biocompatibility and biodegradability: Fe3O4 generally has good biocompatibility and biodegradability and is suitable for use in the biomedical field.


Application Fields

 

Cancer diagnosis and treatment:Fe3O4 nanoparticles can achieve magnetic resonance imaging (MRI), magnetic hyperthermia therapy (MHT) and drug delivery due to their inherent properties.

Medication Delivery:Hollow mesoporous ferric oxide nanoparticles can be used as drug carriers to achieve targeted release of drugs through an external magnetic field, reducing drug dosage and drug side effects, and improving therapeutic effects.

Magnetic hyperthermia:In an alternating magnetic field, Fe3O4 nanoparticles can generate heat and are used to treat cancer, that is, magnetic hyperthermia. The specific heat absorption rate (SAR) of Fe3O4 nanoparticles can be improved by adjusting the core size, adding ingredients, changing the shape and surface modification, thereby improving the magnetothermal treatment effect.

Environmental governance:Fe3O4 nanoparticles exhibit good adsorption performance, chemical stability, and easy separation and recovery in the field of wastewater treatment. For example, Fe3O4 hollow/helical fibers prepared by organic gel thermal decomposition method show excellent adsorption performance in water treatment.

Biosensor:Due to their high specific surface area and good biocompatibility, hollow mesoporous ferric oxide nanoparticles can be used in the construction of biosensors to improve detection sensitivity and specificity.

Great Fit, Lightweight, and Totally Quiet
Size: 11, Color: New Black05
Great fit and very comfortable once you pick the right size. Lightweight, breathable, and completely silent on hard floors. No squeaks or “suction” sounds like some reviews claimed. Normal packaging, normal opening, no issues at all. Excellent value for the price.

Most comfortable shoes I've ever worn
Size: 11, Color: New Black05
First off, I was not expecting much buying a no-name shoe online, especially for the price. Boy was I in for a surprise... I've owned these for almost a full year, and can confidently say these are the most comfortable shoes I've ever worn. I normally wear a size 11 and these fit me perfectly. Prior to this the most comfortable shoes I had were some Cole Haans with the Nike air technology. These shoes are so lightweight, so comfortable, I can wear them all day long without feeling a thing. Whenever I (rarely) need to wear a different pair of shoes, I am immediately reminded of how much I used to hate wearing shoes and couldn't wait to take them off. Based on the price, I expected them to wear down quickly. However they are still going strong. Running, hiking, long walks, biking, worn to office / casual events. These shoes have been soaked in mud multiple times, but clean up easily by just throwing them in the washing machine and then the dryer. The soles and the insoles have both worn down a bit over the past year; at this rate I expect to get 1.5 to 2 years out of them before needing to be replaced. So far I must have put at least a thousand miles on these shoes based on how much I wear them. They look good too. I have the all-black pair, and they look decent with jeans and a button up shirt for a night out, but also look natural in an athletic setting with shorts and no socks. Very versatile and subtle. Now for the cons, which are minor. The pattern on the bottom of the sole is prone to some squeaking/suction sounds at first. However after about a month some of the ridges wore down just enough that it was no longer a problem. Second: they are not as breathable as I would have liked. For example, when running or biking, you don't feel any air on your feet. Wearing them out in the sun on a hot summer day, your feet will get a bit stuffy. In fact the fabric is woven tight enough that I wear them in the winter and in the rain, and don't get too cold or wet. So I do wish they made a more breathable version for summer time use. All that being said, these are still the best pair of shoes I've ever had. Ultra light weight, comfortable, and can be worn all day long without feeling any fatigue whatsoever. --- UPDATE: It's been 1 year and 9 months, and the soles on these shoes are fully worn out and ready for replacement. Considering I've put between 1,000-2,000 miles of walking in these, that's pretty good. If anyone from Feethit is reading this, here are my top suggestions to perfect this shoe: 1) Easy fix - change the tread pattern. The current pattern causes suction cup effect on hard floors until it starts to wear down. Simply add some gaps in the circle pattern in the tread and it will remedy that issue. 2) Most importantly, put a thin piece of durable rubber on the bottom of the sole. The sole does wear down after some time and lose traction, especially on smooth wet floors (e.g. in the rain, in a kitchen, etc.). A thin piece of durable rubber would add more traction and also extend the life of the cushion-like sole (which is fantastic, don't change it!). This would easily be worth an extra $5-$10 in the price.

Nice shoes, despite the squeak and inconsistent sizing
Size: 12, Color: Black White 05
Excellent shoes at this price point. Quite comfortable. They do tend to have a nasty squeak on tile floors, sort of like a suction cup being engaged and disengaged. I bought the navy blue and went back and bought the black. I have to say that the size varied greatly. With the second pair, I have to be sure to wear thin socks and even then, I struggle to get them on, despite having an extremely narrow foot. I'm not sure that a person with an average width foot could wear them. Buyer beware. You may need to go up a size.

My second pair and what they look like after 2 years
Size: 10.5, Color: New Black05, Size: 10.5, Color: New Black05
I wanted to write a review on these shoes. This is my second purchase. I bought the first pair 2 years ago and the bottoms started wearing out, after all it was 2 years. I read reviews saying that they did not hold up well. My pictures show before and after. The reason I purchased again is because I am impressed with the quality and comfort for the money.
