In considering the demands of the body for nourishment and the purposes which foods serve in the body, it was natural that experimenters should direct their attention for a time largely to those questions which were most readily studied, such as the amounts of food eaten and their relation to growth, health, and other physical conditions. The chemical composition of different foods and the purp...

Supersulfated cement, with higher waste utilization and less cement clinker is the inevitable trend of the development of green material in the rapid developed industrial era. For the wide use of supersulfated cement in our country, the hydration heat is analyzed in this paper. The hydration kinetic parameters are obtained from the hydration heat and hydration heat rate curves measured by the i...

BACKGROUND Isothermal calorimetry allows monitoring of reaction rates via direct measurement of the rate of heat produced by the reaction. Calorimetry is one of very few techniques that can be used to measure rates without taking a derivative of the primary data. Because heat is a universal indicator of chemical reactions, calorimetry can be used to measure kinetics in opaque solutions, suspens...

In this paper we present amorphous chromium(III) hydride gels that show promise as reversible room temperature hydrogen storage materials with potential for exploitation in mobile applications. The material uses hydride ligands as a light weight structural feature to link chromium(III) metal centres together which act as binding sites for further dihydrogen molecules via the Kubas interaction, ...

The regulation of the interaction between H2O2 and its catalysts is a promising route to achieve high productivity and selectivity towards H2O2. Herein, mesoporous anatase/TiO2(B) whisker (mb-TiO2) modified with heterogeneous carbon was prepared as the support of Pd-based catalysts for the direct synthesis of H2O2. The morphology and structure of the catalyst were investigated by transmission e...

Crystallization of undercooled Pd43Ni10Cu27P20 melts is studied in a differential scanning calorimeter. Isothermal experiments allow us for the first time to determine the entire crystallization kinetics of a metallic liquid as a function of time from the liquidus temperature to the glass transition temperature. The results are summarized in a time–temperature-transformation (TTT) diagram that ...
