Advanced Functional Materials, EarlyView.While host structures are known to enhance the reversibility and safety of lithium metal deposition, their additional volume and weight often decrease the battery's energy density and specific energy. By combining a lightweight and porous scaffold of electrospun polymer with a thinner separator, this article demonstrates a simultaneous improvement of ...

Two-Molecule Force Spectroscopy on Proteins
ACS Nano, 2023Many elastomeric proteins, which play important roles in a wide range of biological processes, exist as parallel/antiparallelly arranged dimers or multimers to perform their mechanobiological functions. For example, in striated muscle sarcomeres, the giant muscle protein titin exists as hexameric bundles to mediate the passive elasticity of muscles ...

New tools for force spectroscopy
Ultramicroscopy, 2005Force curves using atomic force microscopy have been proposed as a new tool to probe the conformation of adsorbed polymers and interactions between molecules through the analysis of the rupture distributions. We describe an algorithm for the computer-assisted detection of ruptures in force curves.

Molecular Force Spectroscopy on Cells
Annual Review of Physical Chemistry, 2015Molecular force spectroscopy has become a powerful tool to study how mechanics regulates biology, especially the mechanical regulation of molecular interactions and its impact on cellular functions. This force-driven methodology has uncovered a wealth of new information of the physical chemistry of molecular bonds for various biological systems.

Two-dimensional histogram technique is used to determine the loading dependence of friction. Multifunctional dependence F F i (F N )is observed, where the index i represents different materials or inequivalent sites. The data are found to be in agreement with simple power laws, corresponding to the single asperity regime with contact radii of 1–4nm (1 ...

Small Amplitude Atomic Force Spectroscopy
2010Over the years atomic force microscopy has developed from a pure imaging technique to a tool that can be employed for measuring quantitative tip–sample interaction forces. In this chapter we provide an overview of various techniques to extract quantitative tip–sample forces focusing on both amplitude modulation and frequency modulation atomic force ...
