The samples were cooled from 1100°C to room temperature at a rate of 2°C per minute. 2.2. Thermogravimetry Thermogravimetry of ca. 70 mg of each of the Ln1−xSrxCoO3−δ samples was carried out using a SETARAM TAG24 Simultaneous Thermogravimetric and Differential Thermal Analyser. The ...
The FTIR gas-phase spectrum of the decomposition products of a CPC, system B sample measured at 260°C (i.e. after 22 minutes) is shown in Figure 6.16 after subtraction of the dominant ammonia absorptions. The mass spectrum measured at the same time/ temperature is also shown in this fig...
Purple rectangular crystals were collected, washed sequentially with DMF (3 × 10 mL) and acetone (3 × 10 mL), and dried under vacuum at room temperature. 1(S26y51n..04t74h mmesmgi,so0l.o)1wf5 e{mCremom8o(ilPx),eDdHAi2nt)b6au(t2-b0P uTm-ALP...
The Fourier-transform infrared (FT-IR) spectrum of Green ZnO NPs was recorded in Fig.1a in a frequency range of 400–4000 cm−1at room temperature. The peak at 2335 cm–1corresponds to the presence of the O–C–O molecule48, and the peak at 2653 cm–1corresponds to the O–H stre...
By employing Mn powder as a reducing reagent under 1 atm pressure of CO2 at room temperature, diverse alkenyl triflates can be converted to the corresponding α,β-unsaturated carboxylic acids. Moreover, the carboxylation of sterically hindered aryl triflates proceeds smoothly in the presence of a...
Approximately 100% of the cobalt was stripped into the aqueous phase at room temperature and at a contact time of less than 1 minute. It should be noted that the present invention can involve atmosphere controls at two points in the system. The first point is in the extraction circuit. ...
It is therefore an object of the present invention to provide a range of compositions for unidirectionally solidified superalloys which have excellent tensile properties, at room temperature and at temperatures up to 2,000°F. Another object of the invention is to provide cast fiber-strengthened ...
A stable Co3P2O8 structure was developed at 800 °C, although small amounts of Mg2P2O7 were also detected when x ≥ 2.0 at this temperature. This crystalline phase was the only crystalline phase detected in all of the compositions at 1000 °C and when x ≥ 1.5 at 1200 °C. ...
Potentiodynamic polarization tests were performed, at room temperature, on HVOF sprayed coatings in 0.1 N HCl aqueous solution, as corrosive environment. HCl solutions are particularly aggressive towards passivating metals because Cl− ions attack and remove oxide films, causing localized corrosion phenome...
