The cement industry is carbon-intensive, and the valorisation of industrial side-streams/residuals for use as alternative raw materials can enable to reduce its carbon footprint well promote resource efficiency. Apart from key clinker ingredients such CaO, Al2O3, SiO2, residues also contain MgO, CaCl2, SO3. Therefore, this study investigates formation assemblages in system CaO-SiO2-Al2O3-SO3-Ca...

Sorbitol is one of the platform chemicals and can be produced from various renewable sustainable sources via different processes. Hydrothermal liquefaction an effective promising approach to produce sorbitol, since subcritical reaction media appropriate catalysts provide a selective production chemicals. In this study, sorbitol was (cellulose glucose) in presence Ru-based (Ru/SiO2, Ru/AC, Ru/SB...

The water soluble tris-aqua complex [Gd(dhqN-SO3)(H2O)3](3-) based on a hexadentate hydroxyquinoline ligand shows high thermodynamic stability and high relaxivity (12.54 mM(-1) s(-1) at 1.2 T). Its non-covalent confinement in 25 nm silica nanoparticles prevents transmetallation and endogenous anion binding and leads to higher relaxivity over a wide range of magnetic fields.

Cement is produced by co-grinding clinker, gypsum and other components defined in the Cement Standards like limestone, pozzolans, fly ash and slag. The grinding is usually performed in horizontal ball mills. Gypsum is typically the basic source of sulphates (SO3) in the cement. The effect of gypsum on the cement quality is critical and twofold. It affects two of the main properties of this prod...

The free-radical chemistry of sulfite oxidation is reviewed. Chemical transformations of organic and biological molecules induced by sulfite oxidation are summarized. The kinetics of the free-radical oxidations of sulfite are discussed, as are the kinetics of the reactions of the sulfite-derived radicals SO3 and the peroxy derivative SO5 with organic compounds.

The colloid silver sols with defined average particle size were prepared by means of chemical reduction of silver compound [Ag(SO3)2] 3– by several organic redox systems used as development agents in photography. The average size of the particles varied from 700 to 150 nm in dependence on sulphite concentration in reaction system and reduction compound type.

Thermogalvanic hydrogel, an environmentally friendly power source, enable the conversion of low-grade thermal energy to electrical and powers microelectronic devices in a variety scenarios without need for additional batteries. Its toxicity, mechanical fragility low output performance are hindrance its wide application. Here, we demonstrate thermoelectric gels with safe non-toxic, recyclable, h...

In this paper, we study the motion of rigid bodies in a perfect incompressible fluid. The rigid-fluid system fils a bounded domain in R3. Adapting the strategy from Bourguignon and Brezis [1], we use the stream lines of the fluid and we eliminate the pressure by solving a Neumann problem. In this way, the system is reduced to an ordinary differential equation on a closed infinite dimensional ma...
