Experimental studies on multi‐scale data‐driven methods within the framework of structural health monitoring

Civil Engineering Design, EarlyView.
Abstract The German Research Foundation has established the priority program SPP 100+. Its subject is monitoring bridge structures in civil engineering. The data‐driven methods cluster deals with the use of measurements and their special global and local analysis methods, which complement each other in an overall multi‐scale concept in order to realize

Photoinduced Dynamics of [N(C3H7)4]2[Cu4Br6] Thin Films with Dual Self‐Trapped Exciton Emission and Negative Thermal Quenching

ChemPhysChem, EarlyView.
Temperature‐dependent time‐resolved photoluminescence (PL) and transient absorption spectroscopy track the generation and decay of two self‐trapped exciton states (STE1 and STE2) in an [N(C3H7)4]2[Cu4Br6] thin film after photoexcitation. This efficient zero‐dimensional halocuprate(I) emitter shows a quite rarely observed increase of the PL intensity ...

Effect of Ion‐Neutral Collisions on the Plasma Sheath in the Presence of Surface‐Produced Negative Ions

Contributions to Plasma Physics, EarlyView.
ABSTRACT The effect of ion‐neutral collisions on the plasma sheath has been investigated for electronegative plasma in the presence of surface‐produced negative ions. Such sheath structures are commonly found in the negative ion sources. It has been found that ion‐neutral collisions reduce the ion velocity towards the sheath and consequently reduce the

Containerless emulsification of acoustically levitated composite drop

Droplet, EarlyView.
Emulsions are inherently thermodynamically unstable dispersions that are widely involved in food processing, cosmetic preparation, and drug delivery. The existing ultrasonic emulsification techniques mainly rely on the direct contact between the sonicator probe and liquids, which caused localized high temperature and pressure within the liquid and ...

A comprehensive review of experimental studies on shear behavior of bolted rock joints with varying rock joint and bolt parameters and normal stress

Deep Underground Science and Engineering, EarlyView.
This study reviews the research findings on the shear behavior of bolted rock joints in deep underground engineering, where they face high stress, high water pressure, and engineering disturbance. This study examines how the shear strength of bolted rock joints is affected by various factors, such as normal stress, rock compressive strength, joint ...
