Abstract General equations to correlate and predict the thermodynamic properties of hydrated borates were developed based on the experimental results according to their structural types The thermodynamic properties ΔHf0 and ΔGf0 of a hydrated borate phase are the sum of the contributions of the cations in aqueous solution the borate polyanions and the
Engineering thermochemistry is the science and technology that studies innovates and engineers heat induced or heat driven thermochemical reactions and can potentially lead to reductions of five
Chlorite is an important diagenetic mineral in sedimentary basins often found cementing mineral grains and filling pore space in formations that may serve as reservoirs for storing carbon dioxide

The term nanoparticle or nanomaterial is somewhat difficult to define rigorously A nanoparticle has dimensions somewhere in the nanometer regime that is a diameter of 1 to 100 nm Thus nanoparticles span the range from clusters of atoms in solution at the small end to colloidal particles at the large end Nanoparticles may be amorphous or consist of only a few unit cells

Opaque minerals of common granitic rocks were studied microscopically The granitoids were divided into i a magnetite bearing magnetite series and ii a magnetite free ilmenite series Thermochemistry of some pyroxenes and related compounds A Navrotsky W E Coons Chemistry Materials Science 1976; 123 Save
Photosynthesis liberatesO2 from a mixture ofCO2 and H20 in forming biologicalsubstances Formation of fossil fuels is also associated with progressive depletion of oxygen from biological substances The two processes are thus sequential in terms of deoxygenation To evaluate thermochemical relations of the deoxygenation processes in a simple manner the concept of

Chlorites are petrogenetically important minerals exercise controls on petroleum reservoir qualities are common in alteration zones during hydrothermal ore mineralization and may form during carbon sequestration in sedimentary formations Chlorite thermochemistry and structure have been investigated in the present study to facilitate an improved understanding
Advanced Gibbs free energy minimization was applied for modeling physical and chemical processes in various industrial rotary kilns The method is the core of a generic computer program KilnSimu
Vivianite shows a major differential thermal response spanning 65 to 315°C attributable to an endothermal loss of structural water combined with the oxidation of Fe 2 which results in exothermic peak s being described within the endothermal record and consequential breakdown of the original a gradual sintering of the amorphous
