This paper sets out a quantified scenario for the UK to reach net zero carbon emissions. Wind and solar are the main energy sources and their intermittency is accommodated through hydrogen electrolysis, biogas from anaerobic digesters, and their combination into biomethane. Hydrogen and biomethane stocks are tracked. A daily energy balance model is presented, using the most recent recorded weather data-2017 to 2021. Long periods of low wind in 2021 indicated the necessary energy storage capacities, which were adjus [...]

We describe here the coherent formulation of electromagnetism in the non-relativistic quantum-mechanical many-body theory of interacting charged particles. We use the mathematical frame of the field theory and its quantization in the spirit of the quantum electrodynamics (QED). This is necessary because a manifold of misinterpretations emerged especially regarding the magnetic field and gauge invariance. The situation was determined by the historical development of quantum mechanics, starting from the Schrödinger e [...]

A filtered Poisson process is proposed as a model for river flows. With the help of real-life data, the model parameters are estimated. Mathematical formulae are derived in order to estimate the various return periods of the river. An application to two rivers shows that the point estimates are very close to the corresponding values computed by hydrologists, based on historical data. Moreover, by modifying the values of the parameters in the model, we can see the potential effects of climate change on the return pe [...]

Ozone was reacted with the aromatic membrane polyetheretherketone (PEEK) to form oxidized functional groups on the surface to enhance the attraction and transport of protons in fuel cells. Ozonation of unsaturated C-C sp2 bonds in PEEK formed a primary ozonide which dissociated to primarily produce O=C-O/O=C-OH moieties, and the root mean squared roughness factor (Rq) decreased from 7.4 nm, for the untreated sample, down to 3.1 nm. The oxidation of the surface and decrease in surface roughness made the surface incr [...]

Ultraviolet (UV) and X-ray radiation are the primary causes of ionization that produce electron density in sufficient quantities to promote the propagation of satellite radio signals in the ionosphere. The electron densities suffer from spatio-temporal variations, and this poses different degrees of threats to satellite radio signals propagating through the ionosphere. We aimed to characterize the maximum electron density of the F2 layer (NmF2) in the middle-latitude ionosphere over Grahamstown, South Africa (Geogr [...]

Due to recent global warming and climate change events, about 127 countries have declared themselves carbon neutral since the Paris Agreement was signed. Furthermore, agriculture is directly or indirectly affected by climate change. In particular, the importance of carbon neutrality is very high due to the high carbon absorption potential of forestry biomass. In the global beverage market, green tea is the second most consumed beverage after water, and the potential of tea tree biomass to absorb carbon during culti [...]

Around 1600 AD the carbon dioxide content of the earth’s atmosphere started to rise, even whilst according to the Milankovitch [1] astronomical theory of climate variation it was due to fall. On the natural earth the carbon dioxide count of the atmosphere is a delayed response and an enhancing feedback on the basic cause of the Milankovitch astronomical cycle, the intensity of the June sunshine. If the Milankovitch cycle had continued its natural course, the medevial cold period known as the little ice age. Human i [...]

The most commonly used process for fabricating perovskite solar cells is based on wet chemistry, which greatly limits the choice of materials suitable for optimizing the performance of the device. We developed a new approach for the fabrication of perovskite-based solar cells. In the smart stacking process, the perovskite solar cell was assembled by stacking two pieces of perovskite films prepared separately. A working perovskite solar cell was developed with PCE = 0.78% and the perovskite layer was analyzed with X [...]
