Nano Technology Makes Aluminum More Applicable! (2018/11/12)
Aluminum and its alloys have been commonly used in many engineering applications because of high strength to weight ratio and good malleability and ductility. In the case of coating the aluminum surface, the resistance to corrosion, abrasion, and hardness will rise sharply extending its...News Visited Count : (61)
Nanotechnology fights mice this time! (2018/09/29)
It is no longer surprising to see mice in canals. Although different decisions have been planned and performed by municipalities to fight this phenomenon, the mice do not seem to be going anywhere!

Take the harmful impacts of sunlight seriously
Sunlight; harmless or harmful?
The skin of the human body naturally lacks the ability to deal with the harmful effects of the sunlight. Ultraviolet radiation has shorter wavelengths but more energy than the visible light, which makes the radiation more permeable into the skin.
The most well-known types of ultraviolet rays are divided into three UVA, UVB and UVC wavelength ranges. Passing through the atmosphere, all UVC and 90% of UVB are absorbed by the ozone layer, water vapor, oxygen, and carbon dioxide. UVA is less absorbed by the atmosphere though. Therefore, the ultraviolet radiation that reaches the ground involves the entire UVA and the remaining UVB.
These two types of radiation might damage the skin, cause wrinkles, early aging, and increased risk of skin cancer. Harms of UVA rays often appear to be wrinkles, skin dislocation and aging, and UVB rays also contribute to the skin cancer.
Sunscreen products as a protective shield against harmful rays
Despite the proven impact of sunlight on the skin cancer (which is more prevalent in the world than other cancers), the use of sunscreens, which play an important role in protecting ultraviolet radiation, has been doubled. Sunscreens prevent the skin from getting UVA and UVB rays. Ultraviolet radiation protection is applied through two factors (bandgap absorption and UV light diffusion); however, the smaller and Nano-sized particles, the more protection against UVA and UVB rays making uniform spreading on the skin. This uniform expansion helps more particles to protect against ultraviolet rays and absorb them.
More complete protection with Nanotechnology
Nowadays, the issue of nanotechnology in the production of various health and beauty products such as skin-cares, anti-wrinkles, and sunscreens is more considered, and the use of nanoparticles has affected the industry of sunscreens. This type of sunscreen has a number of special features due to the use of nanotechnology that can prevent the harmful effects of ultraviolet rays.
In the meantime, Pars Hayan Company has managed to produce and market a variety of sunscreen products using nanotechnology to protect the skin from adverse effects of sunlight. Ardene colored sunscreen cream SPF 46, Ardene sunscreen cream SPF 35 skin shine and anti-wrinkles, Hydroderms children sunscreen cream SPF 30, Hydroderm sunscreen cream SPF 30 with no chemical absorbents are some of the products offered by this company.
High resistance to ultraviolet rays, longer lifetime and more protection against radiation, higher quality and higher efficiency than chemical products are among the important advantages of using this type of sunscreen creams. Due to its type of structure, the price of this product is only 5 to 10 percent more expensive than chemical samples. In addition, the use of chemical absorbents in the composition of sunscreen cream may cause allergies in some people. On top of that, products containing chemical absorbents are not recommended for pregnant women as well as the children.
One of the current concerns in the use of nanoparticles in cosmetic products is the high absorption of these particles into the skin. However, the nanoparticles used in this product do not enter the cell and remain on the dead-cell layers of the skin.
There are also any sunscreens available on the market to have their own instruction. These creams should be used fifteen to twenty minutes before sun exposure and renewed every two hours, but Nano sunscreens instantly create a protective effect after use, so that they can make a protective layer on the skin immediately after use to form a defensive barrier against ultraviolet rays of the sun.
Does this product have any approvals and permissions?
Pars Hayan Co. is one of the largest manufacturers of personal care and skin care, hair and dental care, and cosmetics products in the Middle East. The portfolio of products for this company includes 300 products (under 11 brands).
The company is one of the manufacturers of health and beauty products that have been using nanotechnology in its products over the past few years and has been successful in producing sunscreens with this technology. The company has been able to obtain international approvals in addition to obtaining a nanoscale certificate from the Nanotechnology Development Organization and approval of the Ministry of Health, Treatment and Medical Education.
Crystal structures of titanium dioxide are used in two forms of rutile and anatase. While the EU has banned the use of the anatase structure in cosmetic products and accepts the structure of the rutile, so Pars Hayan Co. manufactures its products in the rutile structure.

Pars Hayan Co. has used two materials of TiO2 (Titanium Dioxide) and ZnO (Zinc Oxide) to produce these products. However, the share of titanium oxide compounds is higher than that of zinc oxide due to the type of control and easier mechanism of production, and the better protection role.
These two materials have been effective in reducing the UV-damaging effects for a long time and were used in a micro-size that their manufacturing process was accompanied by a lot of complexities and hardships. Now converting them to a size in the Nano-sized, some of the previous problems, such as excessive whiteness when using sunscreens, has now been eliminated. However, the smaller the size of these molecules, the better they can protect against ultraviolet rays.
