Product Overview 

Cerium (Ce) is one of the most abundant and cheap rare earth elements. Due to its unique 4f electronic structure, CE has been widely used in many fields such as alloy, fluorescence, magnetism and catalysis in recent years. Accordingly, its cerium oxide (light yellow powder) has also attracted great attention. The CeO2 crystal structure is cubic fluorite structure, in which the metal cation (Ce4+) is arranged according to the face-centered cubic lattice, while the anion (O2-) is located in the tetrahedron center. Ce elements usually contain two oxidation states, Ce4+ and Ce3+. When the temperature is very high or in a reducing environment, it can be reduced to CeO2-x (0<x¡ãC.5), resulting in the two valence states can be quickly and reversibly converted to each other, so oxygen vacancy defects are very easy to appear in the lattice of CeO2-x. Due to their inherent oxide defects and excellent REDOX properties and oxygen storage capacity, CeO2 nanoparticles are commonly used as heterogeneous catalysts or active oxide carriers of catalysts.

Mesoporous Ceria Nanoparticles (CeO¡ãCNPs) are nanomaterials with mesoporous structures with pore sizes between 2 and 6 nm. The mesoporous structure provides a large specific surface area and more active sites for various reactions.

Product Features

Mesoporous structure: mesoporous pores can not only be used as a material transport channel to promote the diffusion and release of drugs, catalysts or other active substances, but also improve the specific surface area of the material.

High specific surface area: Due to the presence of mesoporous structure, mesoporous cerium dioxide nanoparticles usually have a very high specific surface area, which helps to increase the contact area with the reactants, improve catalytic efficiency or drug loading.

Chemical stability: Cerium dioxide itself is a chemically stable material that can maintain its structure and properties under a variety of environmental conditions.

Biocompatibility: In the field of biomedicine, mesoporous cerium dioxide nanoparticles show good biocompatibility and are suitable for use as drug carriers.

Application Fields

In the field of catalysis: mesoporous cerium dioxide nanoparticles have a wide range of applications in the field of catalysis, such as catalytic reduction of nitrobenzene compounds, automotive exhaust purification. Its high specific surface area and mesoporous structure enable the catalytic reaction to be carried out efficiently on the surface of nanoparticles.

Biomedical field: As a drug carrier or bioimaging agent, mesoporous cerium dioxide nanoparticles also show great potential in the biomedical field. Its good biocompatibility and easy surface functionalization enable the drug to be more efficiently encapsulated and released to the target location.

Energy field: In energy storage and conversion equipment such as fuel cells and lithium-ion batteries, mesoporous cerium dioxide nanoparticles can also be used as electrode materials to improve the energy density and cycle stability of the equipment.

Environmental protection field: Using the catalytic performance of mesoporous cerium dioxide nanoparticles, it can be applied to environmental protection fields such as wastewater treatment and air purification to effectively remove harmful substances and improve environmental quality.

This sunscreen body lotion is quite nice.
Style: Piña Colada
This sunscreen body lotion seems to work well. SPF 30 is the highest I could find with moisturizing capabilities. The smell is a bit overwhelming when you first put it on but it then goes away... so why the added scent. I wish it were SPF 50 and unscented. Otherwise I would have given it 5 stars.

So refreshing, you’ll forget it’s sunscreen.
This stuff is fantastic. I love the super fine mist and how easily the pump works. It is soo refreshing and smells like fresh coconut. Ot doesn’t sting or burn my sensitive eyes, and it leaves my skin feeling revitalized and moisturized, not sticky or tacky. It feels amazing when it’s hot outside and you need a quick refresh and it won’t disturb my makeup. Coola is becoming one of my favorite sunscreen brands.

Wonderful hot weather spritz
Size: 1.7 Fl Oz (Pack of 1)
I used this on a recent cruise to the Mediterranean. A lovely spritz on a hot day really was so refreshing! I highly recommend it! And it smells so good!
