Recent Advances in Methane Pyrolysis: Turquoise Hydrogen with Solid Carbon Production

open access: yesEnergies, 2022
Beside steam reforming, methane pyrolysis is an alternative method for hydrogen production. ‘Turquoise’ hydrogen with solid carbon is formed in the pyrolysis process, contrary to ‘grey’ or ‘blue’ hydrogen via steam methane reforming, where waste carbon ...

Energy Conservation as Security [PDF]

open access: yes, 2006
"Energy security" is usually defined as the guarantee of a stable and reliable supply of energy at reasonable prices. However, this definition is often misleading because it equates oil supply as the primary focus of a country's energy security ...

ENERGY EFFICIENCY AS PRECONDITION OF ENERGY SECURITY

open access: yesJournal of Security and Sustainability Issues, 2015
Increase of energy efficiency remains as one of the major strategic objectives in Lithuania. Effective use of existing energy saving potential increases energy security and reduces emissions of greenhouse gas and other pollutants. In order to meet the growing energy demand and to reduce the negative impact of the energy sector on environment, increase ...

Lived and care experiences of chronic musculoskeletal shoulder pain in Australian adults: A qualitative study

open access: yesArthritis Care &Research, Accepted Article.
Objectives Australian evidence on lived and care experiences of chronic musculoskeletal shoulder pain (CMSP), irrespective of disorder classification or disease, is limited. However, such evidence is important for person‐centred care and informing local service pathways and care guidelines or standards.

Energy Security and Geopolitics [PDF]

open access: yesConnections: The Quarterly Journal, 2007
According to a number of geopolitical strategists, investment bankers, geologists, and physicists, much of humankind will radically change their way of existence in the next twenty to thirty years. The reason? The supplies of cheap energy sources, which are the basis of the modern economy, will be exhausted.

Modelling Atherosclerotic Plaque Cap Mechanics: Microcalcifications Reduce Mechanical Properties in Mesenchymal Stromal Cell‐Based Model

open access: yesAdvanced Biology, EarlyView.
This study develops a tissue‐engineered model of the atherosclerotic cap using human mesenchymal stromal cells (MSCs). After 2 weeks of culture to produce a collagenous matrix, a mineralizing medium induces microcalcifications over 4 weeks. These constructs, imaged with second harmonic generation microscopy, lead to reduced ultimate stress at rupture ...
