Germanium was deposited onto highly oriented pyrolytic graphite (HOPG) with and without antimony in ultra-high vacuum. The surface morphology was analyzed using in situ scanning tunneling microscopy (STM) at room temperature (RT). The film grows exclusively in 3D island mode and was affected...

Growth of Ge, Al and Sb on highly oriented pyrolytic graphite (HOPG) was systematically investigated using in situ scanning tunneling microscopy (STM). At room temperature (RT), three dimensional (3D) clusters of all three elements nucleate and grow at the step edges and defect sites of HOPG....

Electronic band structures and phonon bands of bulk, bilayer and monolayer MoS2 are studied by DFT and GW methods and discussed in the framework of applicability of the 2D model for layered systems. The MoS2 monolayer is found to be a direct gap semiconductor with the top of the valence band and...

A new skeletal mechanism of toluene reference fuels with nitric oxide (TRF-NO) in homogeneous charge compression ignition (HCCI) combustion is presented to investigate the effects of NO in exhaust gas recirculation (EGR) on combustion. The skeletal mechanism of TRF-NO, consisting of 80 species...

A study of the surface structure and electronic properties of (010) KGd<Subscript>0.95</Subscript>Nd<Subscript>0.05</Subscript>(WO<Subscript>4 </Subscript>)<Subscript>2</Subscript> (Nd:KGW) using RHEED analysis and XPS is presented. It is shown that Nd doping has a negligible effect on the core levels of the basic elements. A bombardment of the Nd:KGW crystal with 3-keV Ar ions results...</subscript></subscript></subscript></subscript>

Control of transient emissions from turbocharged diesel engines is an important objective for automotive manufacturers, since stringent criteria for exhaust emission levels must be met as dictated by the legislated transient cycles. On the other hand, bio-fuels are getting impetus today as...

The adsorption of oxygen and potassium on the two-phase system: carbide-modified stepped-W(100) surface (CMT) in contact with the solid solution of carbon in bulk tungsten, was investigated by AES and WF measurements. The CMT surface shows metallic behavior judging from its interaction with K....
