The reaction of nanoscale diamond (ND) powder with an elemental fluorine/hydrogen mixture at temperatures varying from 150 to 470 °C resulted in the high degree of ND surface fluorination yielding a fluoro-nanodiamond with up to 8.6 at. % fluorine content. The fluoro-nanodiamond was used as a precursor for preparation of the series of functionalized nanodiamonds by subsequent reactions with alkyllithium reagents, diamines, and amino acids. The fluoro-nanodiamond and corresponding alkyl-, amino-, and amino acid-nanodiamond derivatives were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transformed infrared (FTIR) and X-ray photoelectron spectroscopy (XPS), and thermal gravimetry-mass spectrometry (TG-MS) measurements. In comparison with the pristine nanodiamond, all functionalized nanodiamonds show an improved solubility in polar organic solvents, e.g., alcohols and THF, and a reduced particle agglomeration. The developed methodology provides an efficient method for the chemical modification of nanodiamond powder, which enables a variety of engineering and biomedical applications of ND derivatives.

Aluminum (Al) atomic and molecular weight, atomic number and elemental symbolAluminum, also known as Aluminium, (atomic symbol: Al, atomic number: 13) is a Block P, Group 13, Period 3 element with an atomic weight of 26.9815386. It is the third most abundant element in the earth’s crust and the most abundant metallic element.Aluminum Bohr ModelAluminum’s name is derived from alumina, the mineral from which Sir Humphrey Davy attempted to refine it from in 1812. It wasn’t until 1825 that Aluminum was first isolated by Hans Christian Oersted. Aluminum is a silvery gray metal that possesses many desirable characteristics. It is light, nonmagnetic and non-sparking. It stands second among metals in the scale of malleability, and sixth in ductility. It is extensively used in many industrial applications where a strong, light, easily constructed material is needed. Elemental Aluminum Although it has only 60% of the electrical conductivity of copper, it is used in electrical transmission lines because of its light weight. Pure aluminum is soft and lacks strength, but alloyed with small amounts of copper, magnesium, silicon, manganese, or other elements it imparts a variety of useful properties. Aluminum was first predicted by Antoine Lavoisierin 1787 and first isolated by Friedrich Wöhler in 1827. For more information on aluminum, including properties, safety data, research, and American Elements’ catalog of aluminum products, visit the Aluminum element page.

Comparisons of Mineral Makeup

Mineral foundations have increased in popularity over the years as people have been drawn to the idea that it’s more natural, therefore kinder to and more comfortable on your skin. Though many people think this just includes powder foundations, liquid formulas can be mineral foundation too.

They call them mineral make up. They call them pure. They say they have only “good things” in them. Is this true? And how do they compare in price? Let’s compare apples to apples. I’ve listed all the well know brands of mineral cosmetics, compared their ingredients, their cost, and their actual cost per gram. Although each company offers several products such as foundations, blushes, eye shadows, etc, I’ve chosen the most popular – foundations – as a basis of comparison. I’ve stacked them against Purely Cosmetics to see how each holds up against the other.

Any ingredient marked in bold contains a non-pure, non-earth mineral. Some even worse: parabens are preservatives that are thought to be linked to breast cancer and early aging of the skin. Bismuth oxychloride is a filler that is a by-product of lead and copper processing and is irritating to the skin.Copper Oxide Nanoparticles is good for you!

This is lengthy, but you’ll find some real eye openers. Your favorite mineral makeup is most likely listed here, as I’ve compared Bare Escentuals, Jane Iredale, GLO Minerals, Sheer Cover, Laura Mercier, Youngblood, PUR Minerals, L’Oreal, and Neutragena to Purely Cosmetics.

Note about micronized particles: The use of micronized titanium dioxide is controversial. Some research indicates that micro-size particles do stay on the surface of the skin and do not enter the bloodstream, while others question the long-term safety of using nanoparticles. Studies have shown that it is possible for micronized titanium dioxide particles to penetrate cells and eventually lead to DNA damage following sun exposure. Asthmatics and others with repiratory problems should be cautioned about using loose powders with micronized ingredients as they are easily airborne. Micronized particles are liked by some mineral makeup companies because they provide a smooth coverage and adhere easily. The smaller the particle, the more sheer and natural looking the application. On the flip side, micronized particles cannot provide medium to full coverage for those who need to cover life’s imperfections.
