Complementary SEM-AFM of Swelling Bi-Fe-O Film on HOPG Substrate

Understanding frictional duality and bi-duality: Sb-nanoparticles on HOPG.

Antimony nanoparticles deposited under UHV conditions on HOPG are found to exhibit an intriguing frictional behavior characterized by a distinct clearly separated double dual behavior of dependence of the frictional force on contact area. We present the first realistic simulations, density functional modeling adapted to accommodate van der Waals interactions, of the (double) dual frictional beh...

AFM, SEM and TEM Studies on Porous Anodic Alumina

Porous anodic alumina (PAA) has been intensively studied in past decade due to its applications for fabricating nanostructured materials. Since PAA's pore diameter, thickness and shape vary too much, a systematical study on the methods of morphology characterization is meaningful and essential for its proper development and utilization. In this paper, we present detailed AFM, SEM and TEM studie...

. bi o - ph ] 1 6 Fe b 20 04 Two complementary representations of a scale - free network

Several experimental studies on different fields as molecular biology, economy, or sociology have shown that real complex networks are following a power-law distribution like P (k) ≈ k −γ. However, many real networks hold two kind of nodes, being able to be projected as two embedded networks, e.g. movie-actor collaboration network (actors network and movies network), metabolic pathways (substra...

Direct electrochemical and AFM detection of amyloid-β peptide aggregation on basal plane HOPG.

Amyloidogenesis is associated with more than 30 human diseases, including Alzheimer's which is related to aggregation of β-amyloid peptide (Aβ). Here, consecutive stages of Aβ42 aggregation and amyloid fibril formation were followed electrochemically via oxidation of tyrosines in Aβ42 adsorbed on the basal plane graphite electrode and directly correlated with Aβ42 morphological changes observed...
