Pulsed coaxial plasma jets for CO2 dissociation at Martian pressures: Magnetic confinement for modeling local supercritical conditions

Results in Physics
This study explores the use of high-density plasma jets, generated by a coaxial plasma gun, for efficient CO2 dissociation into oxygen under Martian pressure conditions (1–5 Torr).

Effect of the Laser Wave Front in a Laser-Plasma Accelerator [PDF]

Physical Review X, 2015
A high repetition rate electron source was generated by tightly focusing kHz, few-mJ laser pulses into an underdense plasma. This high intensity laser-plasma interaction led to stable electron beams over several hours but with strikingly complex transverse distributions even for good quality laser focal spots.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

FEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly

Beam size dependency of a laser-induced plasma in confined regime: Shortening of the plasma release. Influence on pressure and thermal loading [PDF]

, 2021
Processes using laser-shock applications, such as Laser Shock Peening or Laser Stripping require a deep understanding of both mechanical and thermal loading applied. We hereby present new experimental measurements of the plasma pressure release regarding

Effect of electropolishing on vacuum furnace design

Journal of Electrochemical Science and Engineering, 2015
The use of thermal shields of materials having low emissivity in vacuum furnaces is well-known. However, the surface condition of the heat shields is one of the most important factors governing their efficiency as radiation resistances. The emissivity of

Ultra-rapid direct dissociation of CO₂ with dense pulsed plasma jets for Martian oxygen production

Journal of CO2 Utilization
Intense pulsed plasma jets with electron densities of in excess of 10²¹ m⁻³ and temperatures of ∼13 eV were used to dissociate CO₂ under Martian pressure conditions at 1–5 Torr for in-situ oxygen production.

Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA

FEBS Open Bio, EarlyView.
Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.

Backward scattering of laser plasma interactions from hundreds-of-joules broadband laser on thick target

Matter and Radiation at Extremes
The use of broadband laser technology is a novel approach for inhibiting processes related to laser plasma interactions (LPIs). In this study, several preliminary experiments into broadband-laser-driven LPIs are carried out using a newly established ...
