Effects of leading-edge separation on the vortex-induced vibration of an elongated bluff body

Wind-tunnel experiments were conducted to investigate the effects of leading-edge separation on the vortex-induced vibration (VIV) of an elastically-supported elongated bluff body. Solid wind barriers of various heights were fixed in the leading edge to ad ...

Transmission Microsphere-Assisted Dark-Field Microscopy

Stéphane Perrin, Giorgio Quaranta, Hongyu Li

Microsphere-assisted microscopy allows the limit of the diffraction of light to overcome while being non-invasive, full-field, label-free, and easy-to-implement. However, the observation of translucent samples remains difficult using a classical bright-fie ...

MMKG: Multi-modal Knowledge Graphs

Hongyu Li, Alberto Garcia Duran, Ye Liu

We present Mmkg, a collection of three knowledge graphs that contain both numerical features and (links to) images for all entities as well as entity alignments between pairs of KGs. Therefore, multi-relational link prediction and entity matching communiti ...

Benzo[1,2-b:4,5-b ']difuran-based sensitizers for dye-sensitized solar cells

Michael Graetzel, Chenyi Yi, Hongyu Li

Two BDF-based organic sensitizers, as first examples for their use in dye-sensitized solar cells, are prepared and characterized. They yield promising power conversion efficiencies of up to 5.5% and high open circuit voltages up to 0.82 V. This work demons ...
