Interaction of silicate rocks with acid-cut clay muds under pt conditions in the reservoir. Part 2. The mechanism of formation component dissolution

It was established that in case of excess rock to acid-cut clay mud at increase of interaction pressure the selectiveness of dissolution of oxides within Bentonite Clay disappears. In case of excess rock the mechanism of dissolution of these oxides at high pressures is unchanged. Increasing pressure from 0.1 to 15 MPa leads to decreasing Horodyshche gel powder dissolution at higher specific consumption of acid for its dissolution, which is associated with the occurrence of secondary reactions of newly produced neutralizing products

Interaction of silicate rocks with clay-cut acid muds in thermobaric conditions of bed.P.I. Influence of pressure on the solubility of rock

The paper examines dissolution properties of each component of oxides (silicon, aluminum, iron, calcium and magnesium) of Alta-Mud by acid-cut clay mud with increasing pressure. Dissolution of clay mineral sample by acids depending on pressure is an amount of dissolution of each metal oxide. In this case, dissolution of silicon and aluminum oxides with raising pressure increases and concerning other oxides it decreases

Quantum dots desorption via high-power Nd:YAG laser pulses

In the present work, we investigated the mechanism behind the desorption of quantum dots (QDs) CdSe/ZnS (core/shell) aggregates via Q-switched Nd:YAG pulsed laser. After desorption, we trapped the aggregates in a linear quadrupole Paul trap and analyzed their dynamics using machine vision methods. We found that the number of desorbed aggregates is proportional to the laser radiation energy. The injection efficiency was 13.6% for all values of the laser pulse energy greater than 200 mJ. However, even thoughthe desorption process was also observed at lower values (<200 mJ), we did not register particles trapping in this case. This effect might be caused by the different nature of desorption at low powers (LIAD) and at high powers (desorption as a result of substrate ablation)
