Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

The scale free and scale - bound properties of land surfaces: fractal analysis and specific geomorphometry from digital terrain models [PDF]

, 1990
The scale-bound view of landsurfaces, being an assemblage of certain landforms, occurring within limited scale ranges, has been challenged by the scale-free characteristics of fractal geometry.

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

Advanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

Advanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Responses of runoff and sediment yield to rainfall regimes in a typical slope–gully system on the Loess Plateau: A 24-year field monitoring study

Geoderma
Slope–gully system serves as a critical erosion unit on the Loess Plateau, and its slope and gully refer to summit and ridge, and steeper gully wall, respectively.

Energetics of Mode-1 Internal Waves Interacting with Topographic Ridges of Varying Height and Slope

Energetics of mode-1 internal waves interacting with topographic ridges are investigated using high-resolution two-dimensional simulations at spatial scales of m that span between classical laboratory-scale (m) and field-scale simulations (m). This paper

Numerical Investigation of Highway Slope Topographic Effects on Wind Loads of Slope-Mounted Photovoltaic Systems

Applied Sciences
Highway slope-mounted photovoltaic (HSPV) systems are increasingly deployed along expressways, yet wind loads on panel arrays can be strongly modified by slope-induced topographic effects. This study establishes a full-scale CFD framework (ANSYS Fluent, RANS with the SST k–ω model) to quantify the evolution of roadside wind profiles over embankments ...

Correlation between shear-wave velocity and topographic slope

, 2011
The method of using topography as a proxy for average shear wave velocity of upper 30 meters has become an increasingly interesting topic for seismic research mainly because of the advantages it offers such as low cost, simplicity, automation, and its ...
