Biocatalytic membrane can be widely described as a state-of-the-art membrane process in
which biological entity (eg, enzyme) and nanoparticles are used. Such a combination is …

Some remarkable examples of alternative cosmological theories are reviewed here, ranging
from a compilation of variations on the Standard Model through the more distant quasi …

The field of experimental positronium physics has advanced significantly in the last few
decades, with new areas of research driven by the development of techniques for trapping …

The main foundations of the standard Λ Λ CDM model of cosmology are that:(1) the redshifts
of the galaxies are due to the expansion of the Universe plus peculiar motions;(2) the cosmic …

Recent independent observations using several different telescope systems and analysis
methods have provided evidence of parity violation between the numbers of galaxies that …

This book examines the world of cosmological research, providing an in-depth critical review
of the research associated with challenges to the standard Big Bang scenario. It includes …

Quantum vacuum and the matter immersed in it interact through electromagnetic, strong and
weak interactions. However, we have zero knowledge of the gravitational properties of the …

We study the charge of the 4D-Einstein-Gauss-Bonnet black hole by a negative charge and
a positive charge of a particle-antiparticle pair on the horizons r− and r+, respectively. We …

Aims. Observational data show that the observed luminous matter is not sufficient to explain
several features of the present universe, from gravitational structure formation to the …

Repulsive gravity is not very popular in physics. However, one comes across it in at least two
main occurrences in general relativity: in the negative‐r region of Kerr spacetime, and as the …
