using low-dose imaging technique by direct-detection electron-counting camera in a transmission electron microscope, we investigate the atomic structure and decomposition pathway of CH3NH3PbI3(
ICP/SIFT tandem mass spectrometer measurements of room-temperature kinetics have revealed a substantial variation in rates and product distributions across the Periodic Table of Elements. The main features of the observed primary chemistry include H-atom elimination, ammonia addition and a cation-assisted...

Similarly, in side-on N2 adsorption, one of the N atoms is first hydrogenated to form the first NH3 molecule in the consecutive pathway, and two N atoms are simultaneously hydrogenated in the enzymatic pathway. In the determination of the potential-limiting step (PLS) and the maximum ...
1.51 moles of aluminum Moles: One Mole of a substance is always equal to the molar mass of the substance and the number of molecules in one mole of the substance is equal to the Avogadro number. The relation between molar mass and given mass can be ...
Draw the electron shell diagram of an atom with a mass number of 13 and an atomic number of 7. Draw an electron dot diagram for beryllium, showing the correct number of valence electrons. (a) Write the full orbital diagram for Be. (b) Indicate the...
The ultrathin Al2O3 layer deposited at room temperature significantly increases the lifetime of the perovskite solar cells, and we hope this may be a step toward the mass production of stable devices. Graphical Abstract Download: Download high-res image (209KB) Download: Download full-size ...
Undoped and doped tetrahedrally bonded amorphous carbon films (ta-C) were grown in UHV by alternating deposition of low energy mass separated 12C+ ions and dopant ions. For undoped ta-C the fraction of sp3-bonded carbon atoms was determined by EELS as a function of ion energy. The observed...
That is, the amount of the first and second precursors in certain embodiments, provides excess mass in the reactor. The excess mass is provided to ensure an adequate reaction at the surface of the wafer. In this embodiment, the ratio of first precursor and the second precursor components in ...
The amounts of the first precursor gas and the second precursor gas meets or exceeds the amount of material required by the stoichiometry of the particular reaction. That is, the amount of the first and second precursors in certain embodiments, provides excess mass in the reactor. The excess ...
