The rate coefficient of the reaction of OH with CF3CH2F at six temperatures in the range 255-424 K was determined by means of the discharge-flow/resonance-fluorescence technique. The resonance fluorescence of OH, excited by emission from a gaseous mixture of H2O and He subjected to a ...
Since the content of carbon in the medium significantly exceeds that of the nitrogen the Ti–C reaction is a prevailing one. The known experiments support these estimates demonstrating the crystallization of diamond in Fe–C system highly enrich with nitrogen in the form of NaN3. It was found ...
The reaction equation Fe₂O₃ + CO → Fe + CO₂. What is the correct coefficient for CO?
ChemInform Abstract: Room Temperature Rate Coefficient for the Reaction Between CH3O2 and NO3 We have measured temperature dependencies of the rate constants for CO-3 and O-3 reacting with NO and NO2. In addition, the temperature dependence of the C... JN Crowley,JP Burrows,GK Moortgat,......
Fig. 1. Reaction mechanism, morphology, elemental mapping, and crystal lattice of the [Dmei]Cl perovskite films. (A) Proposed mechanism for the in situ formation of the [MTTZ]+ and [DMA]+ cations. (B) Secondary electron image of the [Dmei]Cl film obtained using HIM. The red circle hi...
MgO-impregnated clay of 97.04% is observed at pH 9.0, 60 min contact time, 0.7 g/L adsorbent dosage, and 50 mg/L initial MG concentration. The Malachite green (MG) adsorption isotherm on MgO-impregnated clay corresponded with the Freundlich isotherm, with a correlation coefficient (R2) of ...
The temperature dependence of some three-body association reaction rate coefficients for some rare-gas atomic ion-rare-gas atom reactions of the type A+ 2B → AB+ B have been investigated in the temperature range 100-300 K using a selected ion flow tube technique. The experimental method consi...
Dislocations are linear defects in crystals and their motion controls crystals’ mechanical behavior. The dissipative nature of dislocation propagation is generally accepted although the specific mechanisms are still not fully understood. The inertia, wh
Entropy optimization in convective viscous fluids flow due to a rotating cone is explored. Heat expression with heat source/sink and dissipation is considered. Irreversibility with binary chemical reaction is also deliberated. Nonlinear system is reduced
