Soft Colloidal Robots: Magnetically Guided Liquid Crystal Torons for Targeted Micro‐Cargo Delivery

open access: yesSmall, EarlyView.
Torons, topological quasiparticles in liquid crystals, can be propelled using electric fields and precisely steered with magnetic alignment, enabling programmable motion without fluid flow. In microfluidic channels, they transport colloidal cargo and exhibit novel dynamic behavior. Their uniformity, softness, and reconfigurability make torons ideal for

Characteristics of the Wall Pressure in Impacting Zone at the End of Vertical Plug

open access: yes工程科学与技术, 2019
The vertical plug is a new way to dissipate water energy, in which the flow can be regarded as a submerged jet, and the construction leads to the high velocity and pressure on the wall.

Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

open access: yesSmall, EarlyView.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

open access: yessteel research international, EarlyView.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

3D Numerical Modeling of Circulations Associated with Submerged Buoyant Jet in a Shallow Coastal Environment

open access: yes, 2008
: A three-dimensional numerical model was applied to examine the buoyant jet-driven circulation in Port Moody Arm, Canada. The Arm, which has a relatively shallow water environment of 5 30 m depth, receives considerable cooling water from Burrard Thermal

Ocean acidification, more than warming or heatwaves, constrains shoaling behaviour in a range‐extending fish through habitat simplification

open access: yesJournal of Animal Ecology, EarlyView.
We show that ocean acidification, more than warming or marine heatwaves, alters shoaling behaviour indirectly by simplifying reef habitat and reducing population densities and shoal sizes. Because fish behaviour can be strongly mediated by shoal size, climate‐driven habitat change may reshape social dynamics that influence how range‐extending fishes ...
