Summary: Forming a fundamental understanding of tribological processes on the atomic scale has the potential to revolutionize the control of friction and wear in macroscopic mechanical systems. However, current methods for studying tribology at the nanoscale, such as atomic force microscopy, are limited in scanning speed compared to macroscopic mechanical processes. In this study, a new method combining atomic force microscopy with quartz crystal microbalance measurements is proposed for high-speed nanoscale tribology.

Summary: This article introduces a novel scanning trajectory smoothing method for atomic force microscopes (AFMs), which replaces the backward path of the triangular trajectory with an acceleration-continuous B-spline for the fast axis, and utilizes hysteresis compensation to improve the tracking performance of the scanner. Experiments on a commercial piezoelectric tube scanner demonstrate a significant performance improvement with the proposed method, enabling a five-fold increase in achievable scanning rate from 10 to 50 Hz.

Summary: In this study, we investigated the cargo retention of individual human picobirnavirus virus-like particles with different N-terminal topologies of the capsid protein. Our results show that these different topologies result in distinct cargo release dynamics during mechanical disassembly experiments due to their different interaction with RNA.

Summary: This paper develops an integrated approach to characterize the anisotropic elasticity of endothelium under physiological-level fluid shear stress. The results show that the transverse elasticity of the endothelium in the direction parallel to the flow direction is about 70% higher than that in the perpendicular direction, and the transverse elasticities are estimated to be approximately 120 times larger than the vertical one. These results provide insights into the effects of fluid shear stress on the endothelium's elasticity and anisotropy.

Summary: FtsZ is a key protein in bacterial cell division, and high-speed AFM allows visualization of its filament formation and dissociation process. Analysis shows that FtsZt filaments have different growth and dissociation rates under different conditions, and prefer straight shapes compared to FtsZf filaments.

Summary: The structural dynamics of amyloid protein aggregation process play a role in neurodegenerative diseases. High-speed atomic force microscopy (HS-AFM) is a useful tool to visualize individual aggregate species. Correction of stage drift in HS-AFM images can be done using free software like ImageJ, allowing for easier analysis of structural dynamics.

Summary: Contact-mode high-speed atomic force microscopy (HS-AFM) was used to study in situ stress corrosion cracking (SCC) on AISI Type 304 stainless steel in a salt solution. The findings revealed that grain boundary uplift, oxide formation, and local stress at oxide-weakened boundaries play crucial roles in the SCC process. The study demonstrates the importance of using in situ HS-AFM observations in combination with complementary techniques to gain insights into the mechanisms of SCC.
