While coal is mainly phased out by 2035 in Europe, miniscule shares of oil and gas remain in the energy mix of 2050. This is due to a small number of fossil heating systems that have not reached their end of life by 2050, but they will be phased out shortly thereafter. The shares ...
The liquid–liquid two-phase flow and size prediction of slug droplets in flow-focusing microchannels with different downstream orifice sizes were investigated experimentally. Aqueous solution of 50%-glycerol and mineral oil with 4 wt.% surfactant sorbitanlauric acid ester (Span 20) were used as the...
governments are displaying contrasting behaviors. In the EU, most of the measures that have been rolled out are aimed at lowering the cost of access to energy. As a result, some Member States are delaying or restraining the use of more expensive renewable energies. In contrast, in the USA ...
Abstract The behavior of critical energies E 0, E 1 and E 1 + Δ1 for strained Si, Ge, GaAs and InP is studied using an empirical tight-binding method, with an orthogonal sp3 set of orbitals in the three-center representation. Spin–orbit coupling is taken into account for all four ...
it is mainly the oil companies Repsol (in Spain), TotalEnergies (in France), ENI (in Italy), BP (in Spain and Germany) and soon Shell (in Rotterdam) that have the largest HVO production capacities capable of meeting potential HEFA demand. Asia also has a plant in China, and the United...
Article: Daily Inspiration — High energy from the sun - Now there's a new mystery. There are gamma rays coming from the sun, and some of them have really high energies. With energies like that, you could make cosmic rays out of them without too much tro

We investigate the effect of gas/oil markets (spot/futures) on herding in stock markets in BRICS over 15 years (2007–2022). We consider the effect(s) of crises (Global financial, European debt, COVID-19, and Russia–Ukraine war), bull/bearish energy markets, volatility, and speculation....
