Nitrogen‐Stitched rGO/Graphite Bilayer Anodes for Accelerated Li‐Ion Transport and Interfacial Charge Regulation

Carbon Energy, EarlyView.
Nitrogen‐stitched rGO forms an active charge‐regulating bilayer on graphite that pre‐adsorbs, guides, and delivers Li+ into the lattice. This adsorption–migration–diffusion pathway accelerates Li+ transport, stabilizes the interface, and enables fast‐charging performance beyond conventional graphite limits.

Atomic‐Scale Structurally Locked 1T/2H‐MoS2/ZnS Z‐Scheme Heterojunctions for Prolonged Charge Kinetics and Dual‐Functional Photocatalysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Atomic‐scale structurally locked 1T/2H‐MoS2/ZnS direct Z‐scheme heterojunction enabling dual‐functional photocatalysis. The metallic 1T‐MoS2 phase serves as an electronic actuator that bridges charge transfer across the heterointerface, resulting in prolonged charge kinetics, efficient hydrogen evolution, and complete degradation of Malachite Green ...

Influence of porosity and architecture on the mechanical and acoustic properties of FFF‐printed PLA structures

Polymer International, EarlyView.
The influence of porosity and infill pattern (architecture) on the mechanical and acoustic properties of FFF‐printed PLA is investigated. Ultrasonic analysis highlights the dominant role of interlayer porosity, revealing anisotropic behavior and a transition in elastic properties with increasing porosity.

Electrostatic force spectroscopy revealing the degree of reduction of individual graphene oxide sheets

Beilstein Journal of Nanotechnology, 2018
Electrostatic force spectroscopy (EFS) is a method for monitoring the electrostatic force microscopy (EFM) phase with high resolution as a function of the electrical direct current bias applied either to the probe or sample.

40 years of measuring properties with atomic force microscopy

Journal of Microscopy, EarlyView.
Abstract This paper gives a short personal retrospective of some of the AFM methods developed in the Grutter group. It gives an overview of methods developed with the aim of measuring properties with high spatial and temporal resolution. Frequency mode AFM has over the past 40 years developed into a spatially resolving technique allowing spectroscopy ...

Imaging of stored charges in Si quantum dots by tapping and electrostatic force microscopy

, 2002
We studied the charge storage and subsequent imaging of silicon quantum dots (SiQD) embedded in a $\chem{SiO_2}$ film by using atomic-force microscopy (AFM) in tapping and electrostatic force microscopy (EFM) modes.

Regression Model for a Sensor‐Integrating Jaw Coupling—Compensation for the Viscoelastic Material Behavior

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT In recent years, there has been an increasing demand to digitize production processes. In order to obtain the necessary data for these processes, numerous sensors must be installed on or in the machines. This can be difficult, especially when done retroactively, as the existing installation space must be able to accommodate the sensors.

Nanodielectric mapping of a model polystyrene-poly(vinyl acetate) blend by electrostatic force microscopy [PDF]

, 2010
We present a simple method to quantitatively image the dielectric permittivity of soft materials at nanoscale using electrostatic force microscopy (EFM) by means of the double pass method. The EFM experiments are based on the measurement of the frequency
