Reaction kinetics and thermodynamics are discussed,and surface reactions...
Besides, the kinetic friction of physisorbed molecules on graphene is significantly low, which is desirable for efficient and high speed molecular transportation7–9. Hence, graphene-based materials are promising for constructing mass conveyer systems by applying a temperature gradient or external electric...
The main benefit of using the MBE growth technique compared with others resides in the possibility to use a wide range of in situ diagnostic tools such as ion gauge, quartz crystal microbalance, mass spectrometer and characterization techniques like pyrometry (surface temperature), ellipsometry spectr...
The m/z values of 1 and 2 in matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (Fig. 1 and Supplementary Fig. 3) were 4216.3 and 3784.3 Da, respectively, which precisely match the theoretical molecular mass of the corresponding bilayer structures. The experimental ...
[177]. Yan et al. also generated a similar domain to show that heat generation in a Li-ion battery at the continuum-scale can be affected by the inhomogeneous microstructure of graphite particles and poor contact between particles [178]. As discussed earlier, mechanical stress models typically ...
In addition to the reflection,we also find that the absorption ratio in the positive z side of the graphenebecomes larger, as the mass of the incident isotope becomes larger. On theother hand, the absorption ratio in the negative z side of the graphene becomessmaller. Last, it is found ...

The authors found that smectite with the interlayer cations considered in their investigation was efficient in capturing almost the same mass of carbon dioxide (0.23 ton CO2/m3 of the sample) as in comparison to the zeolite minerals (0.29 ton CO2/m3 of the sample) or metal-organic frameworks ...
The reentrant nematic (n sub re) phase was discovered in 1975 in low molar mass liquid crystals. Since then it received substantial theoretical and experim... Percec, V,M Lee 被引量: 630发表: 1991年 Molecular engineering of liquid-crystal polymers by living polymerization. 3. Influence of m...
Membranes act as selective barriers and play an important role in processes such as cellular compartmentalization and industrial-scale chemical and gas purification. The ideal membrane should be as thin as possible to maximize flux, mechanically robust t
