Revealing Structure–Property Coupling During Thermal Conversion of Metal–Organic Frameworks
Small, EarlyView.Multifrequency atomic force microscopy (AFM) combined with hybrid density functional theory (DFT) and complementary spectroscopic techniques uncovers transient nanoscale states during Cu‐BTC MOF conversion. Intermediate Cu2O/CuO‐carbon nanocomposites maximize mechanical robustness and functionality, while fully oxidized porous CuO enhances light ...

Small, EarlyView.The study demonstrates a dual‐level modification of titania nanotube surfaces through the covalent grafting of Fmoc‐FF dipeptides, followed by a secondary self‐assembled layer of FF dipeptide. This hierarchical strategy significantly enhances coating density and structural integrity without compromising the nano‐topographical and biochemical cues ...

Nanomechanics of advanced polymer fibres [PDF]
Composites Science and Technology, 2009 The micro/nano-structural evolution before and after tensile/compressive loading, fatigue and ultimately, failure has been studied by Raman (and IR) microspectroscopy for PBO, PET, PA66, PP, silk and hair using three probes: low wavenumber collective modes at <150cm-1 as representative of the crystalline/ordered and amorphous chains, stretching and ...

Conformations and cryo-force spectroscopy of spray-deposited single-strand DNA on gold
Nature Communications, 2019 Cryo-electron microscopy can determine the structure but not the nanomechanics of biological matter. Here the authors combine force spectroscopy in cryogenic conditions with computer simulations to characterize the properties of DNA simultaneously down ...

Small Methods, EarlyView.A multimodal imaging approach combines AFM micro‐indentation and MALDI mass spectrometry imaging on the same fresh‐frozen human meniscus section to directly associate microscale mechanics with molecular composition. Collagen‐rich regions exhibit increased stiffness, whereas zones enriched in other extracellular matrix proteins are mechanically less ...

steel research international, EarlyView.To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.This work establishes a laterally homogeneous organic–inorganic hybrid interphase for soft‐short‐free anode‐free sodium metal batteries under extended cycling at high current density and high plating capacity. In contrast to conventional strategies that evolve into laterally heterogeneous interphases and induce localized Na filament growth, the pDFHA ...
