Accurate correction for the matrix interference on laser ablation MC-ICPMS boron isotope measurements in CaCO3 and silicate matrices

Knowledge of the boron isotopic composition of natural samples has found wide ranging application in both low and high temperature geochemistry. More recently, the development of boron isotope measurements using...

Radiogenic and stable Ce isotope measurements by thermal ionisation mass spectrometry

Techniques for the separation of Cerium (Ce) from silicate matrices and for the analysis of radiogenic (ε138Ce) and mass dependent (δ142Ce) Ce isotope variations by Thermal Ionisation Mass Spectrometry (TIMS) are presented in this study.

Nano-dispersed platinum(0) in organically modified silicate matrices as sustainable catalysts for a regioselective hydrosilylation of alkenes and alkynes

Comparative analysis of the catalytic effect of Pt(0) nano-dispersed in siloxane matrices on the hydrosilylation of alkenes and alkynes.

Crystallographic characterization of fluorapatite glass-ceramics synthesized from industrial waste

A series of phase transformations of a novel fluoroaluminosilicate glass forming a range of fluorapatite glass-ceramics on sintering are reported. The sintering process induces formation of fluorapatite, mullite, and anorthite phases within the amorphous silicate matrices of the glass-ceramics. The fluoroaluminosilicate glass, SiO2–Al2O3–P2O5–CaO–CaF2, is prepared from waste materials, such as rice husk ash, pacific oyster shells, and disposable aluminium cans. The thermally induced crystallographic and microstructure evolution of the fluoroaluminosilicate glass towards the fluorapatite glass-ceramics, with applications in dental and bone restoration, are investigated by powder X-ray diffraction and small-angle neutron-scattering techniques.

Properties and Practical Application of Nanoporous Silicate Matrices, Filled with Mixture of NaNO2 and BaTiO3 Ferroelectrics. influence of Co-Encapsulation

Results of research the characteristics of MCM-41 porous silica matrix, encapsulated into her pores by sodium nitrite and its mix with barium titanate were presented. Nature of changes the impedance frequency dispersion, electric loss tangent and dielectric permittivity of intercalates, synthesized under heating, lighting and magnetic field were identified. The conditions, under which the synthesized nanohibrydes can be interesting in terms of formation the structures of electric energy quantum battery and capacitive apexes for reading information from magnetic media, were found.
