Microwave field: Temperature-dependent dielectric properties and heating characteristics during the synthesis of alpha-tellurium dioxide

Novel synthesis of polyaniline/tellurium (PANI/Te) nanocomposite and its EMI shielding behavior

“…Therefore, the composite material can be considered as a PANI/Te nanocomposite with some impurity of tellurium oxide, which is evident from the XRD pattern showing peaks at 2y = 30.02, 30.89, and 44.29, with respective Miller planes (111), ( 102) and ( 211) that correspond to a-TeO 2 . 42,43 By using the Scherrer formula, the average crystallite size for Te nanoparticles was estimated to be about 35 nm in the sample. Overall analysis confirms the formation of PANI/Te with impurities of TeO 2 .…”

Rutile TiO2 Production: Optimization of Microwave Calcination of Metatitanic Acid Using Response Surface Methodology

“…6) reveal a rutile TiO 2 conversion of 99.44 % under the optimized conditions, which is near-identical to the predicted value. Based on the high thermal efficiency of microwave heating [17], which can accelerate dehydration, desulfurization, and nucleation advantages [40,41], compared with other methods [12,22,24] microwave calcination requires a significantly shorter time. Moreover, in heating to the target temperature, only one step of calcination is required, without additional holding to ensure the removal of water and sulfur.…”

“…Therefore, there is an urgent need to develop a new green calcination method with high efficiency and low consumption. Microwave heating is a new green heating method that can directly transfer the required energy to the reacting molecules or atoms [14], with low energy consumption, body heating, and high efficiency [15][16][17]. Thus, we supposed that, by using the advantages of microwave heating, it is possible to develop a new green calcination process with high efficiency and low consumption.…”

Microwave-Assisted Regioselective Synthesis and 2D-NMR Studies of New 1,2,3-Triazole Compounds Derived from Acridone

“…e microwave-assisted synthesis method has become an interesting tool to preserve the environment by reducing the reaction time, efficient internal heat transfer, as well as increasing the yield of reaction [20]. Numerous reactions have proven to result in selectivity or higher yield under microwave irradiation compared with the conventional method [30][31][32]. Among these reactions, the copper(I) catalyzed azide-alkyne cycloaddition (CuAAC) [33].…”
