Small Extracellular Vesicles from Neural Cells: Physiological and Pathological Roles, and Potential in Neurodegenerative Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...

A spectrum measurement system for arc plasma with time and spatial indentification

open access: yesJournal of Measurement Science and Instrumentation, 2015
Spectrum analysis of the plasma has over the years been growing both in methods and instrument,which makes it become a widely used non-contact detection method,without disturbing the arc plasma itself.With noticeable developments in the industry ...

Mechanism and Energy Efficiency Evaluation of Closed-Loop Shock Wave Control Using Arc Plasma

open access: yes气体物理
Plasma actuators have received extensive attention for active flow control due to their advantages of quick response and operational flexibility. The aerodynamic, thermal and chemical effects of the plasma play a dominant role in flow control.

A plasma vortex revisited: The importance of including ionospheric conductivity measurements [PDF]

open access: yes, 2004
In an earlier paper [Kosch et al., 1998], simultaneous all-sky TV imager and Scandinavian Twin Auroral Radar Experiment (STARE) observations of an ionospheric plasma vortex located poleward of an auroral arc were presented.

A New 3D Colon on a Chip to Decipher the Influence of Mechanical Forces on the Physiological Cellular Ecosystem

open access: yesAdvanced Healthcare Materials, EarlyView.
To dissect how mechanical forces influence intestinal physiology, we developed a stretchable 3D colon‐on‐chip that integrates tunable topography, stiffness and peristalsis‐like motion within a physiologically relevant microenvironment. We showed that stretching is a dominant factor governing epithelial behavior, markedly enhancing proliferation and ...

Operating voltage of a W-fuzz cathode arc and the mass/charge composition of the arc plasma depending on the fuzz thickness

open access: yesNuclear Materials and Energy
The arc operating voltage and the mass/charge composition of the arc plasma were measured for W-fuzz samples with different fuzz thicknesses at different numbers of arc pulses.

Droplet Acceleration in the Arc [PDF]

open access: yes, 2006
This paper simulates the acceleration of the droplet in the arc during gas metal arc welding process. After a droplet is detached from the electrode, it is accelerated in the high temperature and high velocity arc to the workpiece.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

open access: yesAdvanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...
