Inspired by the naturally occurring mineral merelaniite, this paper studies a vdW heterostructure composed of a MoS2 monolayer and a PbS bilayer, using density functional theory. A commensurate 2D heterostructure film and the corresponding 3D periodic bulk structure are compared. The results find such a heterostructure to be stable and possess p-type semiconducting characteristics. Due to the heterostructure’s weak interlayer bonding, its carrier mobility is essentially governed by the constituent layers; the hole mobility is governed by the PbS bilayer, whereas the electron mobility is governed by the MoS2 monolayer. Furthermore, we estimate the hole mobility to be relatively high (~106 cm2V−1s−1), which can be useful for ultra-fast devices at the nanoscale.

Nitrogen (N 2) is known to dissociate on iron surfaces, a precursor for ammonia production in the Haber-Bosch process, where the dissociation of N 2 is the limiting step in the reaction at equilibrium conditions. However, little is known about N 2 adsorption on other iron-based materials, such as iron oxide surfaces that are ubiquitous in soils, steel pipelines and other industrial materials. An atomistic description is reported of the binding of N 2 on the Fe 3 O 4 (001) surface using first principle calculations with ambient pressure X-ray photoelectron spectroscopy (AP-XPS). Two primary adsorption sites are experimentally identified from N 2 dissociation on Fe 3 O 4 (001). The electronic signatures associated with the valence band region unambiguously show how the electronic structure of magnetite transforms near ambient pressures due to the binding of atomic nitrogen to different surface sites. Overall, the experimental and theoretical results of our study bridge the gap between ultra-high vacuum studies and reaction conditions to provide insight into other nitrogen-based chemistry on iron oxide surfaces that impact the agriculture and energy industries.

God through others who are themselves becoming Christians.
The issue is not doctrine to be believed. Indeed, one must make a
leap of faith into the fearful and unknown. While it supposedly has little
to do with intellectual conviction and even less with outward evidence of
moral purity and perfection, yet the way one becomes a Christian is experiencing
the truth and being compelled to obey it.

The purpose of this study is to assess the impact of Internet banking on customer retention in CBE. Out of fifteen districts Nekemte District which has 64 branches up to March 31, 2015 was selected purposively, and from these branches seven branches were selected through lottery method.
Moreover, internet banking allows that doing banking transaction even after the regular banking hour. Internet banking is reliable, secure, trust, responsive and privacy maintained. As finding obtained from managers, since internet banking is on introduction stage some transactions such as top up and bill payments are not permitted.
Finally, there is positive relationship between internet banking and customer satisfaction, the factors affect internet banking services are reliability, security, responsiveness and privacy.
The bank should promote internet banking aggressively in order to aware the customer and permit top up, and bill payment accessibility. And also the bank reduces the gap that neutral, disagree and strongly disagree perception of customer. The industry should use fast enough system as compared to customers’ number. The capacity of network infrastructure should be increased.
Regarding to the delayed of transaction the bank should find solution by communicating with telecommunication corporation by maximizing the ADSL capacity.
