Nano Element Particles For Cosmetics

Most of the company’s cosmetics are manufacturing nanotechnology products. They are usually used in the brand-name products such as sunscreen and anti aging products. But what is nanotechnology? In fact, this is a scientific field, control aims to molecular and atomic level of substance. It can make the product more clean, more powerful, more light, the most important thing is cheap. It also can make compound is too small, so it provides a faster and more effective results. However, you should understand that this technology has not been thoroughly tested, which means that it is uncertain whether really safe, especially if you put it in your body as you face the most vulnerable part of.

The FDA has not yet made a lot of research about this. It seems that there have been no reported cases of adverse effects yet. However, there are some experts which are wondering about the safety of these products since when particles will become smaller, new chemical properties will emerge. Since these nanoparticles are very small then they can quickly slip through your skin layers. This means that it will have an interaction with your bloodstream and immune system. The result can be toxic and it can possible damage your tissues. All major cosmetics companies which are producing nano products are always testing their products and they make sure that they are following all laws in order to insure the safeness of their products. However, the FDA will only investigate the safeness of a particular product once it is already in the market. The testing for cosmetics which are using nanoparticles still continues.

Of most concern to a consumer’s problem is that it is toxic. Cosmetics manufacturers of nanotechnology products, because they are cheaper, at the same time provide faster results and many benefits. Cosmetics company selling these skin care products, because they claim they can provide more effective results. Most people choose a skin care products, free of parabens as natural or organic products. Choose cosmetics you should know that these products contain some chemicals can enter the bloodstream, may harm your body and when. In the purchase of a product is best to consult your doctor working in the Department of dermatology. Look before you leap, avoid everything that is said by the sales staff. Perhaps these benefits may be short-lived. The best thing about nano products is that it can provide fast results. But in the application to your face, you have to read the label carefully. Know all the ingredients, and each ingredient to understand everything.

The idea behind this new technology is that if the particle is too small then it can provide better results , about nanotechnology is it can reduce the ingredients of the cosmetics into a nano size form. It is usually too tiny which can be 1/1000 of a human hair. These Nano Element Particles will be absorbed by the skin and it will directly go to the lower levels of your skin where it can provide the needed benefits.

The cells are examined in tiny liquid chambers using the electron microscope

Hongwu International Group Ltd, with HWNANO brand, is a high-tech enterprise focusing on manufacturing, research, development and processing of nanoparticles,nanopowders, micron powders.

With the new analytical technique, the scientists employ electron microscopy to examine protein complexes in whole cells in their natural aqueous environment. The protein in question, the TRPV6 calcium channel forming protein, is first provided with an “anchor” to which a gold Nitrides Nanoparticles can bind. Each Nitrides Nanoparticles thus shows the position of a protein subunit so that the composition of the channels from a multiple of proteins and their locations become visible as they are in the living cell.

The cells are examined in tiny liquid chambers using the electron microscope. “Liquid specimens cannot be studied with traditional electron microscopy”, explains Professor Niels de Jonge, head of the Innovative Electron Microscopy group at the INM. Cells are typically studied in dry state via thin sectioning of solid dried plastic embedded or frozen material, which means that the proteins are no longer in their intact and natural environment. Using tiny liquid chambers the whole cells can now be examined in an aqueous environment. The chambers are made from silicon microchips and have very thin, electron transparent silicon nitride windows.

Research by the electron microscopy experts at the INM is focussing on two aims: “We are keen to perfect our new technology and demonstrate that its application is useful for biological and pharmaceutical research.” Researchers at the INM are therefore working closely with scientists from the Clinical and Experimental Pharmacology and Toxicology Department at the Saarland University..

Prior to this new research nanograined diamond grain structures were limited to between 10 and 30nm

Hongwu International Group Ltd, with HWNANO brand, is a high-tech enterprise focusing on manufacturing, research, development and processing of nanoparticles,nanopowders, micron powders.

Scientists have created synthetic diamonds that are harder and more durable than natural diamonds.

At the Yanshan University, researchers have enhanced fake diamonds by creating nanotwinned diamonds (nt-diamonds)”, according to Nature magazine.

The team explained that previous attempts at creating harder synthetic diamonds using the nanotwinned method failed, as the carbon precursors such as graphite, amorphous carbon, and glassy carbon had not worked.

However recent success in synthesizing nanotwinned cubic boron nitride (nt-cBN) with a twin thickness down to ~3.8?nm makes it feasible to simultaneously achieve smaller nanosize, ultrahardness and superior thermal stability,” the researchers stated.

Prior to this new research nanograined diamond grain structures were limited to between 10 and 30nm, and had degraded thermal stability compared to natural diamonds.

Now the researchers have created the direct synthesis of nt-diamond with an average twin thickness of ~5nm, using a precursor of onion carbon Nitrides Nanoparticles at high pressure and high temperature, and the observation of a new monoclinic crystalline form of diamond coexisting with nt-diamond.

While platinum-group metals (PGMs) make the most stable and active catalysts

Hongwu International Group Ltd, with HWNANO brand, is a high-tech enterprise focusing on manufacturing, research, development and processing of nanoparticles,nanopowders, micron powders. 

In a paper published recently in the journal Angewandte Chemie, an MIT team has explained a process of synthesizing catalysts made using modified tungsten carbide (WC) Nitrides Nanoparticles as an alternative to platinum.

While platinum-group metals (PGMs) make the most stable and active catalysts, they are unsustainable resources.

In this way, tungsten, with six valence electrons, can be electronically modified to mimic platinum, which has 10 valence electrons, by reacting it with carbon (four valence electrons) to give the ceramic material tungsten carbide. Numerous studies have shown that WC is indeed platinum-like, and able to catalyze important thermo and electrocatalytic reactions that tungsten metal cannot such as biomass conversion, hydrogen evolution, oxygen reduction, and alcohol electrooxidation. Importantly, tungsten is more than three orders of magnitude more abundant than platinum in the Earth’s crust, making it a viable material for a global renewable-energy economy. 

The team’s next steps include the synthesis of other bimetallic TMCs, as well as transition metal nitride (TMN) Nitrides Nanoparticles. The team is investigating these materials for other electrocatalytic reactions as well as thermal catalytic reactions, such as hydrodeoxygenation for biomass reforming.

This new method unlocks a broad range of monometallic and heterometallic transition metal carbide and nitride Nitrides Nanoparticles that researchers previously have been unable to synthesize or study,” said Yuriy Rom¨¢n, an assistant professor of chemical engineering who worked on the technology. “While our research focuses mainly on the sustainable replacement of PGMs in thermal and electrocatalytic applications, we also anticipate broader impacts of our new TMC and TMN technologies outside catalysis. Because of their unique chemical, mechanical, and electronic properites, carbides and nitrides have garnered much attention for use in applications as diverse as supercapacitors, medical implants, optoelectronics, coatings, and high-temperature materials for the aerospace and nuclear sectors.”

These high temperatures cause Nitrides Nanoparticles to sinter into large microparticles with low surface areas

Hongwu International Group Ltd, with HWNANO brand, is a high-tech enterprise focusing on manufacturing, research, development and processing of nanoparticles,nanopowders, micron powders.

However, both WC and platinum are heterogeneous catalysts, meaning that they require nanoparticle formulations to create high surface areas and invoke quantum confinement effects to maximize the rates of chemical reactions. While platinum Nitrides Nanoparticles are relatively easy to synthesize, until now, there have been no known methods to synthesize WC Nitrides Nanoparticles less than 5 nanometers and devoid of surface impurities. Tungsten carbide forms at very high temperatures, typically over 800¡ãC (1500¡ãF). These high temperatures cause Nitrides Nanoparticles to sinter into large microparticles with low surface areas. Methods to date that alleviate this agglomeration instead result in Nitrides Nanoparticles
that are covered with excess surface carbon. These surface impurities greatly reduce, or completely eliminate, the catalytic activity of WC.

To solve this problem, the MIT team developed a ¡°removable ceramic coating method¡± by coating colloidally dispersed transition-metal oxide Nitrides Nanoparticles with microporous silica shells. At high temperatures, they show that reactant gases, such as hydrogen and methane, are able to diffuse through these silica shells and intercalate into the encapsulated metal oxide Nitrides Nanoparticles. This transforms the oxide Nitrides Nanoparticles into transition metal carbide (TMC) Nitrides Nanoparticles, while the silica shells prevent both sintering and excess carbon deposition. The silica shells can then be easily removed at room temperature, allowing the dispersal of nonsintered, metal-terminated TMC Nitrides Nanoparticles onto any high-surface-area catalyst support. This is the first method capable of this result.

The team has also been successful in synthesizing the first nonsintered, metal-terminated bimetallic TMC Nitrides Nanoparticles. Electrocatalytic studies have shown that these materials are able to perform hydrogen evolution and methanol electrooxidation at rates similar to commercial PGM-based catalysts, while maintaining activity over thousands of cycles. The catalytic activities obtained were more than two orders of magnitude better than commercial WC powders and WC Nitrides Nanoparticles made by current state-of-the-art synthesis methods that do not prevent sintering or surface carbon deposition..

Such “nanotwinned” crystals are much harder than ordinary diamonds, by a factor of two

Hongwu International Group Ltd, with HWNANO brand, is a high-tech enterprise focusing on manufacturing, research, development and processing of nanoparticles,nanopowders, micron powders.

Diamonds are the hardest naturally occurring minerals known to man. Even so, scientists are working to make them even tougher, in order to use the sparkling gems as tools for cutting.
Now, a team of researchers, led by Yongjun Tian and Quan Huang at Yanshan University in China, has created synthetic diamonds that are harder, meaning they are less prone to deformation and breaking, than both natural and other man-made diamonds.
To create these tougher-than-steel diamonds, the researchers used tiny particles of carbon, layered like onions, and subjected them to high temperatures and pressures. The resulting diamonds had a unique structure that makes them more resistant to pressure and allows them to tolerate more heat before they oxidize and turn to either gas (carbon dioxide and monoxide) or ordinary carbon, losing many of their unique diamond properties.
First, a bit about diamonds: Gem-quality diamonds are single crystals, and they are quite hard. But artificial diamonds used on tools are harder still. That’s because they are polycrystalline diamonds, or aggregates of diamond grains called domains, that measure a few micrometers or nanometers across. The grains help to prevent the diamond from breaking, as the boundaries act like small walls that keep chunks of diamond in place. The smaller the domains are, the stronger the diamond.
Tian’s team used the onionlike carbon Nitrides Nanoparticles to make diamonds with domains that are a few nanometers in size and are mirror images of each other. Such “nanotwinned” crystals are much harder than ordinary diamonds, by a factor of two.
The team tested the artificial diamond’s hardness by pressing a pyramid-shaped piece of diamond into the nanotwinned diamond. Tian’s group made a small indentation in their artificial diamond, applying pressures equivalent to nearly 200 gigapascals (GPa) about 1.9 million atmospheres. An ordinary natural diamond would crush under just half that pressure.
The team also tested how hot the nanotwinned diamond could get before oxidizing. In two different tests, they found that the ordinary diamond began to oxidize at about 1,418 and 1,481 degrees Fahrenheit (770 and 805 degrees Celsius), depending on the testing method. The nanotwinned diamonds didn’t oxidize until they reached 1,796 or 1,932 F (980 or 1,056C).
