Abstract. Although natural CO2-rich groundwaters of eastern Belgium have been known for centuries, the exact origin their gas is still unclear. This paper presents results a sampling campaign in (Spa, Stoumont, Malmedy): 30 samples both carbogaseous and non-carbogaseous were analyzed major elements, CO2 content carbon isotopic composition. Among them, 13 also 3He/4He 4He/20Ne ratios. The combin...

Abstract. The isotopic composition of nitrogen and oxygen in dioxide (NO2) potentially carries a wealth information about the dynamics oxides (NOx = nitric oxide (NO) + NO2) chemistry atmosphere. While isotopes NO2 are subtle indicators NOx emissions chemistry, believed to reflect only O3 / VOC chemical regime different atmospheric environments. In order access this potential tracer tropospheri...

Two organic-inorganic hybrid materials, C6H4(NH3)2∙Cl2 (I) and β-[C6H10N2]2ZnCl4 (II), have been synthesized by hydrothermal method. These two materials are one of the emerged as most brilliant components classes. extraordinary compounds synergistically combine desired physical properties both organic inorganic into a single compound offering possibility to achieve great improvement over time i...

Alkanolamine solutions such as 2-amino-2-methyl-1-propanol (AMP) are widely used in chemical industries for the removal of acid gases such as CO2 and H2S. In this work, the density of CO2, AMP, water, and AMP solutions using the Goharshadi–Morsali–Abbaspour Equation of State “GMA EoS” in the extended 50-degree range of temperatures (313.06-362.65 K) and pressures (0.5-40 MPa) was calculated. Th...

Abstract. A reinvestigation of the type angastonite specimen from Penrice marble quarry, South Australia, shows that published powder X-ray diffraction pattern for mineral corresponds to a mixture crystalline phases plus an amorphous phase. The formula mineral, CaMgAl2(PO4)2(OH)4⋅7H2O, has been found correspond proposal redefinition as phase approved by IMA CNMNC. Amorphous is isotropic with in...

Surface coating of cathodes is an essential process for all-solid-state batteries (ASSBs) based on sulfide electrolytes as it efficiently suppresses interfacial reactions between oxide and electrolytes. Based computational calculations, Li3PO4 has been suggested a promising material because its higher stability with sulfides optimal ionic conductivity. However, hardly applied to the ASSBs due a...

One-dimensional photonic crystals (1D PhCs) have a unique ability to control the propagation of light waves, however certain classes 1D oxides remain relatively unexplored for use as PhCs. Specifically, there has not been comparative study three different PhC structures compare influence layer thickness, number, and refractive index on PhCs transmission. Herein, we transfer matrix method (TMM) ...
