Time-of-Flight Measurements in the Jet of a High-Current Vacuum Arc Thruster

open access: yesAerospace, 2023
Measurements of ion speed in the plume of a pulsed high-current vacuum arc thruster were performed by means of electrostatic probes. The probes were designed to provide direct speed measurements with minimum disturbance on the plasma jet.

Carbon Recycling Through CO2-Conversion for Stepping Toward a Cyclic-C Economy. A Perspective

open access: yesFrontiers in Energy Research, 2020
The conversion of CO2 into added value chemicals, materials and fuels is a case of transition from the linear to the cyclic-C economy, a necessary change for stopping the putative negative effect of CO2 on climate and the environment.

Melatonin Reduces Oxidative Stress in the Right Ventricle of Newborn Sheep Gestated under Chronic Hypoxia

open access: yesAntioxidants, 2021
Pulmonary arterial hypertension of newborns (PAHN) constitutes a critical condition involving both severe cardiac remodeling and right ventricle dysfunction. One main cause of this condition is perinatal hypoxia and oxidative stress. Thus, it is a public

Partial Oxidation of Methane to Syngas Over Nickel-Based Catalysts: Influence of Support Type, Addition of Rhodium, and Preparation Method

open access: yesFrontiers in Chemistry, 2019
There is great economic incentive in developing efficient catalysts to produce hydrogen or syngas by catalytic partial oxidation of methane (CPOM) since this is a much less energy-intensive reaction than the highly endothermic methane steam reforming ...

The role of personality in the assessment of subjective and physiological emotional reactivity : a comparison between younger and older adults [PDF]

open access: yes, 2017
This study brings more clarity on the inconsistent findings on emotional reactivity differences between older (OA) and younger (YA) adults, by examining the influence of (mal)adaptive personality traits on emotional reactivity and by applying several ...

Neuroimaging assessment of cerebrovascular reactivity in concussion: current concepts, methodological considerations and review of the literature

open access: yesFrontiers in Neurology, 2016
Concussion is a form of traumatic brain injury (TBI) that presents with a wide spectrum of subjective symptoms and few objective clinical findings. Emerging research suggests that one of the processes that may contribute to concussion pathophysiology is ...

Seasonal measurements of total OH reactivity fluxes, total ozone loss rates and missing emissions from Norway spruce in 2011 [Discussion paper] [PDF]

open access: yes, 2012
Numerous reactive volatile organic compounds (VOCs) are emitted into the atmosphere by vegetation. Most biogenic VOCs are highly reactive towards the atmosphere's most important oxidant, the hydroxyl (OH) radical.
