Study on turbulence drag reduction of riblet plate in hypersonic turbulent flows

open access: yes, 2020
This paper focuses on turbulence drag reduction of riblet plate in hypersonic turbulent flows. We use direct numerical simulation (DNS) and large eddy simulation (LES) to simulate three-dimensional spatially-developing boundary layer over the flat plate ...

Micropatterned Surfaces with Unidirectional Wetting Properties for Liquid Transport

open access: yesSmall Structures, Volume 7, Issue 2, February 2026.
Micropatterned surfaces that guide droplets in a single direction are gaining attention for their role in liquid transport. This review explores how surface designs enable such behavior, from gravity‐driven flow to stimulus‐responsive movement. It also discusses fabrication techniques, design challenges, and emerging strategies to advance directional ...

Strategies for achieving real‐world robustness in topologically engineered surfaces with special wettability

open access: yesDroplet, Volume 5, Issue 1, January 2026.
Engineered topologies surfaces with special wettability are promising for their ability to precisely customize wetting behaviors and incorporate versatile functionalities, setting them apart from randomly structured surfaces. However, robustness and durability have been hurdles to their broad application.

Caenogastropods and heterobranch gastropods from the Hettangian deposits of Luxembourg: palaeobiogeography and Early Jurassic faunal recovery in the western Tethys

open access: yesPapers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract We describe the Hettangian Caenogastropoda and Heterobranchia of the Luxembourg Sandstone Formation, a wedge of clastic sediments deposited along the eastern margin of Paris Basin during the Early Jurassic. Five new genera and 11 new species are erected: Bourguetia bipartita sp. nov., Globularia delsatei sp. nov., Oonia feidtorum sp.
