This Special Issue on carboranes is dedicated to Prof. Alan Welch on the occasion of his retirement and his outstanding contributions to the field of carborane chemistry. Polyhedral carboranes lie at the interface of organic and inorganic chemistry. One of their most attractive and important features is the variety and beauty of their chemical structures. They have found applications as diverse as catalysis, in Boron Neutron Capture Therapy, as liquid crystals and as semiconductors. This Special Issue illustrates the very comprehensive world of heteroborane chemistry, from liquid crystals to BNCT agents, di-halogen bonding to quantum chemical calculations of tetrel complexes of the carbonium ylide CB11H11, nickellacarboranes as potential acid–base sensors to revealing how the selective formations of metallacarborane diastereomers can arise and metallacarboranes as function as radical cation salts with dielectric or semiconductor properties.

Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis (MTB) and it represents a persistent public health threat for a number of complex biological and sociological reasons. According to the most recent Global Tuberculosis Report (2019) edited by the World Health Organization (WHO), TB is considered the ninth cause of death worldwide and the leading cause of mortality by a single infectious agent, with the highest rate of infections and death toll rate mostly concentrated in developing and low-income countries. We present here the editorial section to the Special Issue entitled “Mycobacterium tuberculosis Pathogenesis, Infection Prevention and Treatment” that includes 7 research articles and a review. The scientific contributions included in the Special Issue mainly focus on the characterization of MTB strains emerging in TB endemic countries as well as on multiple mechanisms adopted by the bacteria to resist and to adapt to antitubercular therapies.

Clay minerals are inexpensive and available materials with a wide range of applications (adsorbent, ion exchanger, support, catalyst, paper coating, ceramic, and pharmaceutical applications, among others). Clay minerals can be easily modified through acid/basic treatments, the insertion of bulky ions or pillars into the interlayer spacing, and acid treatment, improving their physicochemical properties.Considering their low cost and high availability, clay minerals display a relatively high specific surface area in such a way that they have a great potential to be used as catalytic supports, since they can disperse expensive active phases as noble metals on the porous structures of their surfaces. In addition, the low cost of these supports allows their implementation on an industrial scale more easily than other supports, which are only feasible at the laboratory scale. Hydrotalcites (considered as anionic or basic clays) are also inexpensive materials with a great potential to be used as catalysts, since their textural properties could also be modified easily through the insertion of anions in their interlayer spacing. In the same way, these hydrotalcites, formed by layered double hydroxides, can lead to their respective mixed oxides after thermal treatment. These mixed oxides are considered basic catalysts with a high surface area, so they can also be used as catalytic support.

Cet ouvrage ouvre une fenêtre sur la transmission des lettres de Paul en arabe. Il s’interroge sur le manque d’intérêt depuis le début du 20ème siècle pour les manuscrits arabes du Nouveau Testament et apporte une contribution à la récente reprise scientifique de ce champ, en étudiant le corpus largement inexploré des manuscrits arabes des lettres de Paul. Après un état des lieux établi à l’aide d’un répertoire de manuscrits, l’étude se concentre sur un manuscrit, le Vaticanus Arabicus 13. L’édition de la Première lettre aux Corinthiens de ce document du 9ème siècle est suivie d’une analyse linguistique et philologique pointue ; elle permet de dégager des éléments exégétiques qui mettent en lumière l’intérêt théologique du texte. This work provides an insight into the transmission of the Letters of Paul into Arabic. It aims to understand the lack of interest since the beginning of the 20th century for the Arabic manuscripts of the New Testament and to contribute to the current scholarly rediscovery for this field by studying the largely unexplored corpus of the Arabic manuscripts of the Letters of Paul. After a broad overview with the help of a list of witnesses, the study focuses on a specific manuscript: Vaticanus Arabicus 13. The edition of First Corinthians of this 9th century document is followed by a close analysis of linguistic and philological aspects, while the underlining of interesting exegetical points reveals the theological interest of the text.

The increased international transportation and trade over the last few decades have increased the risk of the introduction of pathogens into new areas. Global climate change has influenced environmental conditions and the ability of pathogens to survive, and has changed the habitats of certain vectors and hosts. These processes have led to the emergence or re-emergence of various pathogens in different parts of the world, including those affecting horses. This Special Issue features some aspects regarding several well recognized as well as some new and emerging equine viral pathogens, highlighting the need for updated epidemiological data. Such surveillance is crucial for proper decision making by clinicians and by regulatory authorities. Also demonstrated by the recent global emergence of SARS-CoV-2, the development of an effective infrastructure for the rapid and effective detection and control of novel viral pathogens, as well as re-emerging ones, is essential. Horses should play an important role in such surveillance systems, not only for equine pathogens but also as sentinels to other viruses and arboviruses. As was demonstrated in several examples in this Special Issue, it is important to remember, both as clinicians and as researchers, that when facing clinical cases, even when those are common, we should remain alert to the possibility of the intrusion of unknown pathogens and, therefore, should seek a definitive diagnosis. This may allow for the early detection of emerging or re-emerging pathogens.

Molecular magnets show many properties not met in conventional metallic magnetic materials, i.e. low density, transparency to electromagnetic radiation, sensitivity to external stimuli such as light, pressure, temperature, chemical modification or magnetic/electric fields, and others. They can serve as “functional” materials in sensors of different types or be applied in high-density magnetic storage or nanoscale devices. Research into molecule-based materials became more intense at the end of the 20th century and is now an important branch of modern science. The articles in this Special Issue, written by physicists and chemists, reflect the current work on molecular magnets being carried out in several research centers. Theoretical papers in the issue concern the influence of spin anisotropy in the low dimensional lattice of the resulting type of magnet, as well as thermodynamics and magnetic excitations in spin trimers. The impact of external pressure on structural and magnetic properties and its underlying mechanisms is described using the example of Prussian blue analogue data. The other functionality discussed is the magnetocaloric effect, investigated in coordination polymers and high spin clusters. In this issue, new molecular magnets are presented: (i) ferromagnetic high-spin [Mn6] single-molecule magnets, (ii) solvatomagnetic compounds changing their structure and magnetism dependent on water content, and (iii) a family of purely organic magnetic materials. Finally, an advanced calorimetric study of anisotropy in magnetic molecular superconductors is reviewed.
