PAYMENT OF THE CAPITAL CONTRIBUTION OF A COMPANY LIMITED BY SHARES IN A CRYPTOCURRENCY
The paper examines whether cryptocurrencies, such as Bitcoin, may be contributed to the share capital of a company limited by shares. The issue is discussed from the point of view of Swiss and Croatian law. In Switzerland, it is an already established practice that cryptocurrencies are accepted as a contribution in kind. On the other hand, in Croatian practice, there have been no registered cases of such attempts. The paper therefore analyses whether such contributions would even be possible under the current regulatory framework and, irrespective of the answer, if some legislative changes would be necessary and/or beneficial
Boosting VOCs elimination by coupling different techniques
International audienceVolatile Organic Compounds (VOCs) are known to be hazardous and harmful to human health and the environment. In mixtures or during repeated exposures, significant toxicity of these compounds in trace amounts has been revealed. In vitro air-liquid interface approaches underlined the interest in evaluating the impact of repeated VOC exposure and the importance of carrying out a toxicological validation of the techniques in addition to the standard chemical analyses. The difficulties in sampling and measuring VOCs in stationary source emissions are due to both the complexity of the mixture present and the wide range of concentrations. The coupling of VOC treatment techniques results in efficient systems with lower operating energy consumption. Three main couplings are outlined in this review, highlighting their advantages and relevance. First, adsorption-catalysis coupling is particularly valuable by using adsorption and catalytic oxidation regeneration initiated, for example, by selective dielectric heating. Then, several key aspects of the plasma catalysis process, such as the choice of catalysts suitable for the non-thermal plasma (NTP) environment, the simultaneous removal of different VOCs, and the in situ regeneration of the catalyst by NTP exposure, are discussed. The adsorption-photocatalysis coupling technology is also one of the effective and promising methods for VOC removal. The VOC molecules strongly adsorbed on the surface of the photocatalyst can be directly oxidized by the photogenerated hole on the photocatalyst (e.g., TiO2).Les composĂ©s organiques volatils (COV) sont connus pour ĂȘtre dangereux et nocifs pour la santĂ© humaine et l'environnement. Dans des mĂ©langes ou lors d'expositions rĂ©pĂ©tĂ©es, une toxicitĂ© significative de ces composĂ©s Ă l'Ă©tat de traces a Ă©tĂ© rĂ©vĂ©lĂ©e. Les approches in vitro de l'interface air-liquide ont soulignĂ© l'intĂ©rĂȘt d'Ă©valuer l'impact d'une exposition rĂ©pĂ©tĂ©e aux COV et l'importance de procĂ©der Ă une validation toxicologique des techniques en plus des analyses chimiques standard. Les difficultĂ©s d'Ă©chantillonnage et de mesure des COV dans les Ă©missions de sources fixes sont dues Ă la fois Ă la complexitĂ© du mĂ©lange prĂ©sent et Ă la large gamme de concentrations. Le couplage des techniques de traitement des COV permet d'obtenir des systĂšmes efficaces dont la consommation d'Ă©nergie est rĂ©duite. Trois couplages principaux sont prĂ©sentĂ©s dans cette revue, en soulignant leurs avantages et leurs pertinences. Tout d'abord, le couplage adsorption-catalyse est particuliĂšrement intĂ©ressant en utilisant l'adsorption et la rĂ©gĂ©nĂ©ration de l'oxydation catalytique initiĂ©e, par exemple, par un chauffage diĂ©lectrique sĂ©lectif. Ensuite, plusieurs aspects clĂ©s du procĂ©dĂ© de catalyse par plasma, tels que le choix de catalyseurs adaptĂ©s Ă l'environnement du plasma non thermique (NTP), l'Ă©limination simultanĂ©e de diffĂ©rents COV et la rĂ©gĂ©nĂ©ration in situ du catalyseur par exposition au NTP, sont discutĂ©s. La technologie de couplage adsorption-photocatalyse est Ă©galement l'une des mĂ©thodes efficaces et prometteuses pour l'Ă©limination des COV. Les molĂ©cules de COV fortement adsorbĂ©es sur la surface du photocatalyseur peuvent ĂȘtre directement oxydĂ©es par le trou photogĂ©nĂ©rĂ© sur le photocatalyseur (par exemple, TiO2)
