Experimental Investigation on Flow-Induced Vibration of Fuel Rods in Supercritical Water Loop

Science and Technology of Nuclear Installations, 2014
The supercritical water-cooled reactor (SCWR) is one of the most promising Generation IV reactors. In order to make the fuel qualification test for SCWR, a research plan is proposed to test a small scale fuel assembly in a supercritical water loop.

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

Advanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Flow Induced Vibrations in Engineering Systems and the Control of Flow Induced Vibrations. Chaotic Vibration in Poppet Valve Circuit.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1995
In the previous paper we pointed out that chaotic vibrations can occur in poppet valve circuits due to nonlinearities. The chaotic motions in the poppet valve circuits include (a) period-doubling-type chaos, (b) Lorenz-type chaos and (c) intermittent-type chaos. In this paper, period-doubling-type chaos has been investigated in detail.

Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Prediction of the Flow-Induced Vibration Response of the Chenderoh Dam Left Bank Section

MATEC Web of Conferences, 2018
Flow-induced vibration is a common phenomenon that happened in any of dam structures during the operational condition. This includes the effect of water spilling from the upstream to the downstream of the dam due to high water volume at the upstream side.
