Modeling of Refractive Indices for Binary Aqueous Solutions of Some Alkane Polyols at Constant Temperature and Pressure

In this research, a theoretical study has been undertaken on the density and also on the relationship between refractive index and density for aqueous solutions. A simple linear equation is suggested to show this relationship. Also, a semi-empirical equation has been developed for estimating the constant of this linear equation. By using our suggested equations, the refractive indices of aq...

Low-temperature olivine rheology at high pressure

San-Carlos olivine rheology was investigated at pressure (P) up to 9 GPa and temperature (T) lower than 890 ◦C. Six powder specimens were cold compressed and sintered into dense and compact materials, then deformed during relaxation experiments carried out at constant pressure and temperature in DIA-type cubic-anvil apparatus. Sample elastic strain was monitored during relaxation by in situ X-r...

Aqueous Catalytic Polymerization of Olefins

Aqueous catalytic polymerization may seem like a contradiction at first sight. The high water sensitivity of Ziegler or Phillips catalysts applied commercially for the production of polyolefins is well known. However, water offers a unique combination of properties as a medium for polymerization reactions: A high heat capacity, which enables an effective transfer of the heat of polymerization. ...

Copolymerization of polar monomers with olefins using transition-metal complexes.

Transition-metal catalysts long ago made it from the laboratory bench to the polymerization reactor. Indeed, they are being used around the world to make more than 70 million tons of polyethylene and polypropylene a year. Transition-metal catalysts give polyolefin producers unprecedented flexibility in process and polymer design. However, there are still new worlds for catalysts to conquer. One...

Synthesis of MgB2 at Low Temperature and Autogenous Pressure

High quality, micron-sized interpenetrating grains of MgB₂, with high density, are produced at low temperatures (~420 °C < T < ~500 °C) under autogenous pressure by pre-mixing Mg powder and NaBH₄ and heating in an Inconel 601 alloy reactor for 5-15 h. Optimum production of MgB₂, with yields greater than 75%, occurs for autogenous pressure in the range 1.0 MPa to 2.0 MPa, with the reactor at ~50...
