Download Rating: Chemical Experiment SimulationPAID Doing chemical experiments on the phone Chemical Experiment Simulation is a software that simulates hands-on chemical experiments on mobile phones. At the same time, it also contains a lot of rich chemical knowledge. It... ...
which can facilitate chemical reactions.For example,the adsorption experiment of Nb2O5nanotubes on CC(Nb2O5@CC)was operated by immersing the samples(containing 10 mg of Nb2O5)into 50 mL of methylene-blue(MB)solution(20 mg L−1).After 2 h,90.5%of MB was adsorbed,implying a high ...

The chemical nature of these superconducting phases and the location of the intercalated metals in the chalcogenide structure is not trivial. For CuxBi2Se3, synthesised at high temperatures from the elements, Cu is reckoned to be inserted in the van der Waals gap between the Bi2Se3 quintuple ...

DRS X-ray photoelectron spectroscopy (XPS) was utilized to analyze the surface chemical states and compositions of the resulting samples. The survey spectrum of IN10 reveals the presence of In, Nb, and O elements in the hybrid nanofibers (Supplementary Fig.3). In the high-resolution In 3dXPS...
of the Na2SO4molten salt [37]. However, some researchers have found that the formation of Nb2O5may not be beneficial for the heat resistance of Nb addition alloys [38,39]. Moreover, the effect of Nb on heat resistant corrosion is closely related to the chemical composition of the ...
Thus, heterovalent doping is considered as a method to change the Fermi level position, and therefore to manipulate the chemical reactivity of the adsorbed molecules. Another approach based on statistical analysis of the large array of experimental data of photocatalytic activity accumulated for various...
Many arguments in favor of chemical experiment, both old and new ones, were put forward. It was demonstrated that chemical experiment is valuable by itself and instrumental in teaching and forms metadomain skills. The idea that chemical experiment should form concepts rather than illustrate them was...
The previous electrochemical results have suggested that T-Nb2O5 possesses a good battery performance owing to its unique properties such as layered structure, high chemical stability and open intrinsic framework [20]. Nonetheless, the poor intrinsic electrical conductivity (3×10−6 S cm−...
