1. Smart Products Report 2022: selected insights

Author

Zimmermann, J. L., Görgen, J., De Bellis, E., and Hofstetter, Reto

Abstract

Der Smart Products Report ist eine repräsentative Studie zur Nutzung und Wahrnehmung von smarten Produkten in der Schweiz, die nun in ihrer zweiten Auflage erscheint. Smarte Produkte sind Produkte für den privaten Gebrauch, die Daten sammeln und verarbeiten, um auf ihre Umgebung reagieren zu können. Damit sind sie zunehmend in der Lage, ohne menschliches Zutun zu agieren. Die Studie differenziert zwischen fünf Produktkategorien: Haushalt, Unterhaltung, Gesundheit und Sport, Hausautomation und Mobilität. Das Smartphone wird von den Betrachtungen der gesamten Studie explizit ausgeschlossen. Einer allgemein weiten Verbreitung und positiven Wahrnehmungen smarter Produkte stehen persönliche und gesellschaftliche Bedenken entgegen. Der zukünftige Erfolg smarter Produkte hängt daher auch davon ab, dass alle Akteure sowohl die von den Verbraucherinnen und Verbrauchern wahrgenommenen Vorteile als auch ihre spezifischen Bedenken in Bezug auf smarte Produkte erkennen und berücksichtigen., + ID der Publikation: unilu_59960 + Titel der Reihe: Swiss Consumer Studies + Sprache: Englisch + Letzte Aktualisierung: 2023-02-23 13:02:19

10. Decontamination of Space Equipment Using Cold Atmospheric Plasma

Abstract

Cold atmospheric plasma (CAP) is a very effective technology for the inactivation of microorganisms, which is of crucial interest for extraterrestrial space missions. In our study, a new designed plasma-gas circulation system has been developed and tested. The investigations with bioindicators (Bacillus atrophaeus) show that this technology has a high sterilization effect. Therefore, several treatment volumes were tested to optimize the CAP efficacy. In addition, we plan to perform a series of measurements for chemical composition by using a FTIR spectrometer. This provides an insight into the plasma chemistry including the influence of the humidity on the inactivation of microorganisms. In this contribution, we propose a possible design of decontamination system for larger spacecraft facilities using CAP. Furthermore we will discuss the advantage of CAP technology in comparison with conventional sterilization methods.

43. Plasma medicine: an introductory review.

Author

Kong, M. G., Kroesen, G., Morfill, G., Nosenko, T., Shimizu, T., van Dijk, J., and Zimmermann, J. L.

Subjects
PLASMA gases, ELECTRIC fields, ATMOSPHERIC pressure, EUKARYOTIC cells, PROKARYOTES, PARACRINE mechanisms
Abstract

This introductory review on plasma health care is intended to provide the interested reader with a summary of the current status of this emerging field, its scope, and its broad interdisciplinary approach, ranging from plasma physics, chemistry and technology, to microbiology, biochemistry, biophysics, medicine and hygiene. Apart from the basic plasma processes and the restrictions and requirements set by international health standards, the review focuses on plasma interaction with prokaryotic cells (bacteria), eukaryotic cells (mammalian cells), cell membranes, DNA etc. In so doing, some of the unfamiliar terminology-an unavoidable by-product of interdisciplinary research-is covered and explained. Plasma health care may provide a fast and efficient new path for effective hospital (and other public buildings) hygiene- helping to prevent and contain diseases that are continuously gaining ground as resistance of pathogens to antibiotics grows. The delivery of medically active 'substances' at the molecular or ionic level is another exciting topic of research through effects on cell walls (permeabilization), cell excitation (paracrine action) and the introduction of reactive species into cell cytoplasm. Electric fields, charging of surfaces, current flows etc can also affect tissue in a controlled way. The field is young and hopes are high. It is fitting to cover the beginnings in New Journal of Physics, since it is the physics (and nonequilibrium chemistry) of room temperature atmospheric pressure plasmas that have made this development of plasma health care possible.

44. Focus on Plasma Medicine.

Author

Morfill, G. E., Kong, M. G., and Zimmermann, J. L.

Subjects
PLASMA gases, LIFE sciences, EUKARYOTIC cells, PROKARYOTES, THERAPEUTICS, CELL membranes
Abstract

'Plasma Healthcare' is an emerging interdisciplinary research topic of rapidly growing importance, exploring considerable opportunities at the interface of plasma physics, chemistry and engineering with life sciences. Some of the scientific discoveries reported so far have already demonstrated clear benefits for healthcare in areas of medicine, food safety, environmental hygiene, and cosmetics. Examples include ongoing studies of prion inactivation, chronic wound treatment and plasma-mediated cancer therapy. Current research ranges from basic physical processes, plasma chemical design, to the interaction of plasmas with (i) eukaryotic (mammalian) cells; (ii) prokaryotic (bacteria) cells, viruses, spores and fungi; (iii) DNA, lipids, proteins and cell membranes; and (iv) living human, animal and plant tissues in the presence of biofluids. Of diverse interests in this new field is the need for hospital disinfection, in particular with respect to the alarming increase in bacterial resistance to antibiotics, the concomitant needs in private practices, nursing homes etc, the applications in personal hygiene-and the enticing possibility to 'design' plasmas as possible pharmaceutical products, employing ionic as well as molecular agents for medical treatment. The 'delivery' of the reactive plasma agents occurs at the gaseous level, which means that there is no need for a carrier medium and access to the treatment surface is optimal. This focus issue provides a close look at the current state of the art in Plasma Medicine with a number of forefront research articles as well as an introductory review. [ABSTRACT FROM AUTHOR]
