Summary: This study overcomes the challenge of loss of spatial resolution in Atomic Force Microscopy (AFM) due to long-range interactions by selectively extracting single metallic nanoclusters grown on graphene. The created nanotips are stable and can be used to explore different surfaces without loss of resolution, opening up possibilities for specific functionalization of AFM tips to sense a variety of interactions.

Summary: A simple and high-yield method for generating atomic force microscopy (AFM) probes with self-sharpened silicon tips is presented. The method involves controlled chemical etching using a cost-effective etchant solution. The fabricated AFM probes show high yield and consistent tip radius, and produce images comparable to commercially available probes.

Summary: In this paper, we validate an experimental model of contact resonance atomic force microscopy designed for sensors with long, massive tips. We develop a new technique and graphical method for identifying unknown system parameters and experimentally validate both the technique and the contact resonance model. Our contact resonance experimental measurements show a minimal error of 1.4%-4.5% compared to values obtained from nanoindentation, demonstrating the accuracy of the new model and parameter identification technique.

Summary: Inspired by TENG, scanning TENG is proposed for local surface charge density measurement using atomic force microscopy. The technique taps a conductive tip above a charged dielectric surface to induce an AC, with Fourier analysis showing a linear relation to surface charge density. Results demonstrate its power in probing nanoscale charge transfer in contact-electrification.

Summary: Investigating internal resonance (IR) mechanisms in micro/nanoresonators reveals that intermodal coupling between second and third flexural modes in asymmetric structures provides an optimal condition for strong IR, with high energy transfer to the resonated mode. This study introduces design strategies that can be easily integrated into typical micro/nanoelectromechanical systems, offering potential for paradigm-shifting applications in micro/nanosystems.

Summary: Controlling the identity of the tip-terminating atom or molecule in low-temperature atomic force microscopy has led to significant advances in surface chemistry and nanotechnology. Comparing four atomically defined tips, it was found that Cu-tips react with surface oxygen, while Xe and CO tips allow for increased resolution due to their chemical inertness. CuOx-tips, with higher rigidity and selectively increased chemical reactivity, prevent tip-bending artifacts and generate a distinct chemical contrast, which holds promise for future studies on metal-oxide surfaces.

Summary: The conventional assumption that the tip of the silicon is infinitely stiffer than the force gradient between it and the test object is not true at short distances in aqueous environments, where the effective tip is an adsorbed water molecule. We introduce a new multifrequency technique to measure the surface force gradient independently from the weak H-bond.

Summary: This study investigates the mechanism of friction at sliding contacts, proposing that friction can be explained by considering the damping of stick-slip pulses. The findings provide a basis for reconciling controversies in literature studies on friction and suggest possible tactics for controlling friction.

Summary: This study utilizes two-photon polymerization to manufacture 3D polymeric atomic force microscopy (AFM) tips, known as 3DTIPs, with flexible design and functionality. By using common AFM modes in air and liquid environments, the 3DTIPs successfully achieve high-resolution and high-speed AFM imaging. The functionality of the 3DTIPs is extended by refining the tip end, allowing for higher-resolution AFM imaging.

Summary: This study investigated the effects of drying temperature, plasticizer type and dosage on the molecular structure of konjac glucomannan (KGM), agar, and curdlan polysaccharides. The results showed that the molecular morphology of different polysaccharides changed at different drying temperatures. Adding a suitable amount of plasticizer can relieve the shrinkage of hydrophilic polysaccharide molecular chains during drying. Glycerol showed better performance in relieving molecular chain shrinkage compared to Tween 20 and Tween 80. Lastly, a new method for preparing polysaccharide samples for atomic force microscopy (AFM) was proposed, which provided a new idea for observing polysaccharide morphology.

Summary: This article introduces a novel method to generate Coulombic force in KPFM, increasing the spatial resolution to approximately 25 nm. By integrating PiFM, high spatial resolution chemical distributions and surface potential maps can be obtained concurrently. This is expected to facilitate characterizations of nanoscale electrical properties of photoactive materials, semiconductors, and ferroelectric materials.

The SC light source was used to demonstrate the first NIR, spectrally resolved s-SNOM measurement and characterize the dispersion curve of surface plasmon polariton (SPP) waves in the NIR, representing a technological breakthrough for potential new applications in near-field studies.

Summary: This study demonstrates a new method to enhance the coupling constant of a single quantum emitter by collectively coupling multiple nearly degenerate transitions of the emitter to the same field mode. The resulting effective Jaynes-Cummings model shows a boosted coupling constant of order root N, retaining quantum optical nonlinearities. The findings closely match recent experiments and will aid in controlling and detecting single-photon nonlinearities at ambient conditions.
