This paper presents the results of provenience analysis siliceous artefacts from Neolithic lakeshore settlements studied in scope SNSF-project MET (“Mobilities, entanglements and transformations societies on Swiss Plateau (3900-3500 BCE) supported by National Science Foundation (Project No 100011 156205). The aim this is to compare cultural as defined pottery studies with regions origins knappa...

Lithofacies identification and classification are critical for characterizing the hydrocarbon potential of unconventional resources. Although extensive applications machine learning models in predicting lithofacies have been applied to conventional reservoir systems, effectiveness clay-rich, lacustrine shale has yet be tackled. Here, we apply well log data automatically identify Gulong Shale So...

A significant reduction in the CO2 emission associated with cement production is obtained by partially replacing Portland supplementary cementing materials (SCM’s): e.g., siliceous fly ash or granulated blast furnace slag. In near future, limited availability of these will do more attractive to use ashes from combustion fluidized bed boilers, which currently are mainly deposited various landfil...

The present contribution provides a study of calcareous nannofossils and siliceous microfossils from the Sawai Bay Formation on Car Nicobar Island, northern Indian Ocean. Two stratigraphically short sediment intervals near have been examined. Qualitative quantitative microfossil analyses show ‘A’ Section to be devoid microfossils, while 24 well-preserved nannofossil taxa are identified. ‘B’ yie...

Adsorption of methanol and ethanol over mesoporous siliceous material are studied in the current paper. The pure mesoporous silica is prepared using tetraethylorthosilicate (TEOS) as silica source and dodecylamine as template at low pH. The prepared material was characterized using nitrogen adsorption,nX-ray diffraction (XRD) and scanning electron microscopy (SEM). The adsorption kinetics of me...

We have investigated the dynamics of water molecules in zeolites NaA and NaX by high-resolution quasielastic neutron scattering methods. Between 260 and 310 K, the local translational diffusive motion of water in the zeolites is one to two orders of magnitude slower than in bulk water. The Q dependence of the scattering shows effects of confinement and the presence of both relatively mobile and...
