Analysis and test of superplastically formed titanium hat-stiffened panels under compression [PDF]

Four hat-stiffened titanium panels with two different stiffener configurations were fabricated by superplastic forming/weld brazing and tested under a moderately heavy compressive load. The panels had the same overall dimensions but differed in the shape

Label‐Free Sensing of Coronaviral Sequences via Kretschmann‐Configuration Reflectance Spectroscopic Ellipsometry: Sensitivity, Specificity, and Interfacial Effects

Advanced Materials Interfaces, EarlyView.
Spectroscopic ellipsometry in the Kretschmann‐Raether configuration (KRSE) is employed to characterize a DNA‐functionalized platform for viral sequence recognition. By merging SE with surface plasmon resonance, KRSE outperforms conventional SE, achieving nanomolar targeting through resonance wavelength shifts (δλ) measurements. Its enhanced interfacial

Fabrication Method of Directional Microstructure for High Energy Density, High Power Battery Cathodes

Advanced Materials Interfaces, EarlyView.
Aqueous directional ice templating (DIT) is developed for making NMC811 cathodes containing vertically aligned pore arrays through electrode thickness. The effects of calendering are studied for the DIT electrodes to find optimal calendering and simultaneously achieve high gravimetric and volumetric energy densities and rate capability for lithium ion ...

Volume-controlled buckling of thin elastic shells: Application to crusts formed on evaporating partially-wetted droplets

, 2006
Motivated by the buckling of glassy crusts formed on evaporating droplets of polymer and colloid solutions, we numerically model the deformation and buckling of spherical elastic caps controlled by varying the volume between the shell and the substrate ...

Selected Problems of Determining Critical Loads in Sructures with Stable Post-Critical Behaviour. [PDF]

, 2016
This paper presents selected cases of inapplicability of theory based methods of determining critical loads in thin – walled, composite tubes. 8th layered composite tubes with square cross-section were being subjected to static compression and in order ...
