Development of an in operando uniaxial fatigue testing regime for the linear plasma device Magnum-PSI

open access: yesNuclear Materials and Energy
Tokamak divertors may be exposed to cyclic thermomechanical loads during service, giving rise to the fatigue cracking of plasma-facing monoblocks. Fatigue is a surface-sensitive dislocation-mediated degradation phenomenon, and monoblock fatigue life may ...

Investigating Fatigue Performance on the Foamed Asphalt Specimens Generated Using Different Foam Properties [PDF]

open access: yes, 2012
An evaluation of fatigue resistance for foamed asphalt mixture is very demanding since the binder is not continuously distributed on the aggregate surface and this mixtures contains water, the content of which dramatically affects the mechanical ...

Exploring the Potential of Zero‐Dimensional Carbon Nanomaterials in Photoluminescent, Electrochemiluminescent and Electrochemical Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
Zero‐dimensional carbon nanomaterials are presented as multifunctional platforms linking structure, property, and sensing performance. Surface engineering and heteroatom doping modulate electron‐transfer and luminescent behavior, enabling electrochemical, photoluminescent, and electrochemiluminescent detection. Fundamental design principles, analytical

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

open access: yesAdvanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Very high cycle fatigue resistance improvement of Mg-Gd-Zn-Zr alloy by introducing curved long-period stacking ordered lamellae

open access: yesJournal of Magnesium and Alloys
Magnesium alloys with long-period stacking ordered (LPSO) structures are known for their impressive static mechanical strength, but the consistent occurrence of slip-cracking along the LPSO lamellae, which do not effectively impede the movement of basal ...

Performance of TenCate Paving Interlayers in Asphalt Concrete Pavements [PDF]

open access: yes, 2017
As a continued effort of a previously completed project entitled “Performance of TenCate Mirafi PGM-G4 Interlayer-Reinforced Asphalt Pavements in Alaska,” this project evaluated two newly modified paving interlayers (TruPave and Mirapave) through overlay,

Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor

open access: yesAdvanced Materials Technologies, EarlyView.
We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into

Estimating the fatigue law of asphalt mixtures using a strain sweep test (EBADE test) [PDF]

open access: yes, 2013
Fatigue characterization of asphalt mixtures is a very important issue. However, existing techniques to that end are expensive and time consuming. For that reason the asphalt technicians have been studying several different methods to reduce the testing ...
