Turbulence for (and by) amateurs

open access: yes, 2000
Series of lectures on statistical turbulence written for amateurs but not experts. Elementary aspects and problems of turbulence in two and three dimensional Navier-Stokes equation are introduced.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

open access: yesAdvanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Lattice Structures for Bone Replacement: The Intersection of Bone Biomechanics, Lattice Design, and Additive Manufacturing

open access: yesAdvanced Materials Technologies, EarlyView.
This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...

Extreme‐Temperature Resistant, Flexible, and Sensitive Strain Sensor for Aerospace Parachute Deployment

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, we report a resistive‐type strain sensor fabricated using single‐walled CNTs, are used layer using the pray technique to deposit as conductive, and UV‐resin was spin‐coated as a protection layer. The sensor functioned in harsh temperature variation conditions from −50°C to 125°C without deterioration.

Adaptive Carbon Nanotube Patches for Versatile Electronic Textiles and Wind‐Harvesting Applications

open access: yesAdvanced Materials Technologies, EarlyView.
An adhesion‐tunable electronic textile patch based on a carbon nanotube/paraffin composite is presented, enabling direct, adhesive‐free integration with fabrics. Pressure‐responsive bonding allows reversible or permanent attachment on demand.

Experimental and Numerical Study of Shock Waves in Contractions [PDF]

open access: yesعلوم و مهندسی آبیاری, 2014
Shock waves are often occurring during passage of supercritical flow in the non-prismatic channels. In the present study, values of height and instantaneous velocities were measured in various points of shock waves observed in two contractions with fixed

Kolmogorov-Burgers Model for Star Forming Turbulence

open access: yes, 2001
The process of star formation in interstellar molecular clouds is believed to be controlled by driven supersonic magnetohydrodynamic turbulence. We suggest that in the inertial range such turbulence obeys the Kolmogorov law, while in the dissipative ...

Two‐Photon Polymerized Microvascular Environments for Multicellular Modeling of the Blood–Brain Tumor Barrier

open access: yesAdvanced Materials Technologies, EarlyView.
Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.

Numerical Simulation of Atmospheric Turbulence for Assessment of Wind Turbine

open access: yesJournal of Fluid Science and Technology, 2011
To obtain basic understanding for the development of atmospheric turbulence assessment technique for wind-energy application, we examine the performance of turbulence simulation using the large-eddy simulation technique, focusing on grid dependency of ...

Stochastic inviscid shell models: well-posedness and anomalous dissipation

open access: yes, 2012
In this paper we study a stochastic version of an inviscid shell model of turbulence with multiplicative noise. The deterministic counterpart of this model is quite general and includes inviscid GOY and Sabra shell models of turbulence.
