Here, it is reported direct atomic scale evidence that oxygen vacancies formed in the GBs can modify the local surface oxygen dynamics in CeO2, a key material for fuel cells. The atomic structures and oxygen vacancy concentrations in individual GBs are obtained by electron microscopy and ...
Synthesis and characterization of Li(Ni1/3Co1/3Mn1/3)0.96Si0.04O1.96F0.04 as a cathode material for lithium-ion battery The layered cathode materials of LiNi 1/3Co 1/3Mn 1/3O 2 were prepared at 770 °C under oxygen atmosphere using the precursor of (Ni 1/3Co 1/3Mn 1/3)(OH) ...
oxygen as an example: Firstly, 1152 oxides with a first-principles-calculated bulk modulus in MP database were extracted. Then, we determined the atomic stiffness of oxygen (7.52 eV) by minimizing the difference between the predicted bulk moduli from our formula and first-principles-calculated...

.oxygen in water, carbon in methane, or both atoms in cellulose. Asmolecular hydrogenhas to be produced, the relative greenness of the production processes merits analysis; we do this here qualitatively. The analysis is notably based on the 12principlesof green chemistry. After an overview of ...
Afterwards, unwanted graphene is removed using oxygen (O) reactive ion etching (RIE) to fabricate a defined channel. Finally, the whole device was loaded into a helium ion beam lithography (HIBL) machine to create the desired graphene nanoribbon (GNR) patterns. The GNRs showed exceptional ...
Adsorption of oxygen on a Pd(111) surface studied by high resolution electron energy loss spectroscopy (EELS) Oxygen adsorption on a Pd(111) surface has been studied in the temperature range from 30 K to 300 K by high resolution electron energy loss spectroscopy (EELS) and by low energy ele...
The use of UV radiation sources while monitoring ozone holes from space is discussed. The method is based on the ability of ozone to absorb UV radiation in a wide wavelength range (λ < 310 nm), thus providing intense pumping of the atomic and molecular oxygen excited states. The ozone con...
