Isomeric Ag14 Nanoclusters With Distinct Photophysical and Nanomechanical Properties

Advanced Science, EarlyView.
Ligand‐shell isomerism in atomically precise Ag14 nanoclusters is demonstrated to regulate core distortion, photoluminescence, and mechanical properties. Subtle changes in phosphine ligand arrangement drive a pronounced emission shift from green to red and alter crystal rigidity, revealing a direct structure‐property correlation that offers new design ...

Unveiling the Influence of natural weathering on the nanomechanical properties of magnetorheological elastomers

Results in Engineering
Examining the physical aging of materials is essential for assessing their long-term performance and determining their suitability for specific applications. Material aging involves changes from their initial state, including deterioration or degradation.

Ductile B2 Intermetallics‐Driven Strength‐Ductility Synergy in Heterolaminated Multi‐Principal Element Alloys

Advanced Science, EarlyView.
Intrinsic phase toughening transforms a brittle B2 intermetallic into a plastically deformable, load‐bearing phase, while a heterogeneous laminated architecture suppresses strain localization and interface cracking. The synergy between ductile intermetallics and mesoscale heterogeneity establishes a general design strategy for breaking the long ...

Thermodynamic, Structural, and Nanomechanical Properties of a Fluorous Biphasic Material

The Journal of Physical Chemistry B, 2008
The dynamics of the amphiphilic semifluorinated F(CF2)12(CH2)12H (F12H12) alkane that undergoes two condensed phase transitions have been investigated by Brillouin light spectroscopy, shear rheometry, small- (SAXS) and wide-angle (WAXS) X-ray scattering, and thermodynamic PVT measurements.

Generalized Hertz model for bimodal nanomechanical mapping

Beilstein Journal of Nanotechnology, 2016
Bimodal atomic force microscopy uses a cantilever that is simultaneously driven at two of its eigenmodes (resonant modes). Parameters associated with both resonances can be measured and used to extract quantitative nanomechanical information about the ...

Nanomechanical properties of neutron-irradiated concrete

Acta Polytechnica CTU Proceedings
Concrete exposed to irradiation from nuclear reactor undergoes atomic-level degradation due to the influence of neutrons, secondary gamma rays, and associated gamma heating. The radiationinduced damage decreases the mechanical properties of the concrete
