چکیده

It is shown that the antisymmetry of the sphalerite structure is isomorphous to the coloured diamond group Fd'3'm if sites associated with positive and negative charge are regarded as being equivalent except for colour. This methodology enables the multiplicity and polarity of external crystal surfaces to be deduced readily. In addition this analysis is shown to be very useful for the analysis of domain boundaries, grain boundaries and epitaxial interfaces.

Glow Discharge Depth Profiling a Powerful Analytical Technique in Surface Engineering (TECHNICAL NOTE)

A variety of analytical techniques have been developed and employed to characterize the surfaces, subsurfaces and interfaces of surface engineering systems. They provide important information for quality control, process optimization and further development. Since the mid 1980's, glow discharge spectrometry (GDS) has emerged as an important and versatile technique for rapid depth profiling anal...

Insights from the structural analysis of protein heterodimer interfaces

Protein heterodimer complexes are often involved in catalysis, regulation, assembly, immunity and inhibition. This involves the formation of stable interfaces between the interacting partners. Hence, it is of interest to describe heterodimer interfaces using known structural complexes. We use a non-redundant dataset of 192 heterodimer complex structures from the protein databank (PDB) to identi...

Fluoroalkylated silicon-containing surfaces-estimation of solid-surface energy.

The design of robust omniphobic surfaces, which are not wetted by low-surface-tension liquids such as octane (γlv=21.6 mN/m) and methanol (γlv=22.7 mN/m), requires an appropriately chosen surface micro/nanotexture in addition to a low solid-surface energy (γsv). 1H,1H,2H,2H-Heptadecafluorodecyl polyhedral oligomeric silsesquioxane (fluorodecyl POSS) offers one of the lowest solid-surface energy...

Tuning electronic and magnetic properties of wurtzite ZnO nanosheets by surface hydrogenation.

Through density functional theory computations, we systematically investigated the structural, electronic, and magnetic properties as well as the relative stabilities of fully and partially hydrogenated ZnO nanosheets. Unlike bare ZnO nanosheets terminating with polar {0001} surfaces, their hydrogenated counterparts preserve the initial wurtzite configuration. Full hydrogenation is more favorab...

Molecular dynamics simulation of a binary mixture lubricant for use in hard disk interfaces

In Hard Disk Drives (HDD), it is necessary to decrease the Flying Height (FH) between the head and the disk (currently, FH is around 3-5 nm) so as to increase recording densities. Retaining the solid lubricant has become a difficult proposition owing to intermittent contact between the surfaces. ZTMD and Z are used as solid lubricant to lubricate these interfaces. In this paper, the behavior of...
