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

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

Advanced Materials, EarlyView.We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Resonant snubber based soft-switching inverters for electric propulsion drives [PDF]
, 1996 This paper summarizes recently developed soft-switching inverters and proposes two alternative options for electric propulsion drives. The newly developed soft-switching inverter employs an auxiliary switch and a resonant inductor per phase to produce a ...

Experimental verification of an improved soft-switching cascade boost converter
, 2017 A soft switching cascade DC-DC boost converter is proposed in this paper. The proposed cascade single switch converter has a higher step-up voltage gain and a wider turn-of period compared to classical boost converters, which tend to have a problem of ...

Parallel soft switching converter with fewer switch counts
Electronics Letters, 2018 A parallel direct current (DC) to DC converter is presented for medium power applications. The studied converter includes three half‐bridge circuits with sharing two power switches at high‐voltage side to reduce switch counts. Three half‐bridge circuits are connected by primary‐parallel and secondary‐parallel to reduce the current stress of power ...
