US7118611B2 Nanoparticle mixtures for hydrogen storage
This invention uses nanoparticle mixtures to broaden the range of economic materials, improve performance across this broader range, and thereby lower costs of hydride and other storage systems. Nanoparticles can have dramatically different mechanical, chemical, electrical, thermodynamic, and/or other properties than their parent (precursor) materials.
Fast separation: 2 D: Method with short analysis times (e.g., <1 min) H: High‐resolution separation: 1 D, 2 D: Method capable of high peak capacity. I: Isocratic: 1 D, 2

Furthermore, wider 2 D columns can be operated at higher flow rates, reducing the delay of gradient delivery caused by system dwell volumes. However, the combination of (i) a high 2 d
- What are the primary antioxidants for polymers?
- The majority of primary antioxidants for polymers are sterically hindered phenols. Part of primary antioxidants, are aromatic amines, mainly used in carbon-black filled rubbers and some polyurethane applications. Irganox ® 5057 is such an aromatic amine for polyol and rubber stabilization.
- What is Irganox ® 245?
- Irganox ® 245 is a hindered phenolic antioxidant designed to protect the substrates against thermo-oxidative degradation during manufacturing, processing and end use. It is suitable for styrene polymers and other polymer applications.
- How do antioxidants protect polymers from oxidation?
- Antioxidants protect polymers against oxidation by controlling molecular weight changes that lead to a loss of physical, mechanical, and optical properties. Among other factors heat, light and mechanical stress can result in the degradation of the polymer.
- What is the difference between antioxidant 168 and antioxidant 1010?
- Antioxidant 168 is a white crystalline powder, melting point 181-184℃,soluble in benzene, toluene, gasoline, insoluble in water ... Antioxidant 1010 is an odourless white crystalline powder. At 20 ℃g/100ml solvent : acetone 47, benzene, 56, chloroform 71, ethy... Compound with antioxidant 215 by antioxidant 1010 and antioxidant 168 distribution.
