Comprehensive Theoretical Studies on Fluorine Oxide Species

Juliandri Juliandri, Rustaman Rustaman

World Scientific News > 2023 > 177 > 68-78

The development of Density Functional Theory (DFT) has created a new era in approaches to theoretical chemistry. High accuracy combined with computational economy are most important aspects in the success of the DFT. The reactions of halogens with ozone in the atmosphere have been discovered as a potential source of ozone depletion. As experimental studies are difficult to perform, theoretical approaches...

Theoretical Studies on Chlorine and Bromine Oxides

Juliandri Juliandri, Haryono Haryono

World Scientific News > 2023 > 178 > 44-55

The existence of the ClO radical was first suggested in the 1920s, following studies of the photosensitized decomposition of gaseous Cl2O. It was one of the first indirect evidences that a transient species, namely ClO, was involved in the chemistry of this decomposition. The chlorofluorocarbon (CFC) example became a classic example of how man-made materials and our widespread use of them can dramatically...

VUV Radiation and Protons cannot produce the Shroud Body Image

Giovanni Fazio

World Scientific News > 2023 > 178 > 1-11

In this paper we investigate the radiative hypothesis, already proposed by other scientists, as being the mechanism that may have produced the Shroud Body Image. We are critics of the above process, because it is incomprehensible to both Physics and Theology. Moreover, due to the presence of air in addition to linen, it is impossible to penetrate to the same depth all the points of the region where...
