In addition, although the structure distribution is not known, nanotubes with diameters of 8–25 nm have been obtained by this approach 24. Recently, several studies have attempted to reduce their diameter and narrow their diameter distribution by modifying the synthesis of oxide nanowires as a result, nanotubes with diameters of 70 nm 27 and 20 nm 28, 29 have been fabricated from oxide nanowires synthesized from chemical vapor-deposition (CVD) and solvothermal methods, respectively. Therefore, to synthesize small-diameter nanotubes with few walls, it is necessary to synthesize small-diameter oxide nanowires. In this process, the oxide nanowires are synthesized and then converted into nanotubes by sulfurization. One approach to synthesize TMDC nanotubes is the chalcogenization of transition metal oxide nanowires, which has been used for large-scale synthesis 22. Although the synthesis of MoS 2 nanotubes with small diameters outside carbon nanotubes and inside boron nitride nanotubes has been reported 25, 26, the structure–property relationship in small-diameter WS 2 nanotubes has not been experimentally investigated to date. In contrast, very few studies 24 have investigated the properties of small-diameter WS 2 nanotubes because of their challenging synthesis (owing to the high folding energy of WS 2 sheets). Most of the studies to date have been performed on relatively large-diameter multiwall nanotubes (~ 100 nm) 21, 22, 23 and have revealed structure-dependent properties, such as size-dependent exciton-polaritons 17, structure sorting optical properties 16, and light-matter interactions 14. Thus, an important goal in this field is to clarify the correlation between the properties and nanotube structures experimentally. In particular, WS 2 nanotubes with small diameters are expected to exhibit significant band structure modulation due to curvature effects 15, 19, 20, leading to unique properties different from those of WS 2 sheets and WS 2 nanotubes with large diameters. It has been theoretically predicted that the electronic structure of WS 2 nanotubes depends on the nanotube structure, which is characterized by the nanotube diameter 14, 15, 16, 17 and wall number 18. Owing to their chiral nanotube structures, WS 2 nanotubes exhibit several interesting properties, such as nonreciprocal conduction 8, 12 and bulk photovoltaic properties 12, 13. Unlike carbon nanotubes, WS 2 nanotubes exhibit solely semiconducting properties regardless of how they are rolled 4 and show advantages for applications such as sensors 5, field effect transistors 6, 7, 8, optoelectronic devices 9, 10, and thermoelectric devices 11. Therefore, by using it you can find an answer to the question, what is the time now in the time zone you're interested in.Tungsten disulfide (WS 2) nanotubes 1 are cylindrical nanotubes composed of WS 2 sheets, which are semiconducting transition metal dichalcogenides (TMDCs), and have attracted significant attention over the past few decades owing to their unique electronic, optical, and optoelectronic properties 2, 3. It is a unique online tool to help our users convert UTC time into the current time in a certain time zone. Those who plan a trip or an online meeting with their overseas business partners, those who have friends on the other continents and want to make a call at a convenient time can use this fast and effective UTC time zone converter. In addition, you can also see a few types of UTC time format, with some being very widespread, and some being less commonly used. In order to learn the current time in UTC, it is enough for you just to open the main page of our website. Since the 1970s, this time standard has been globally used as the most precise time standard, instead of formerly used GMT standard, which has turned now into a regular time zone. UTC, or Universal Time Coordinated, is the most precise and commonly referred to time standard. Here, you can learn what time is it in UTC time now and what the most accurate time now is, use our UTC time zone converter designed to easily convert time from current time in UTC to one of over a hundred presently existing time zones, as well as use some useful links at the bottom of the page collected for you by the experts of our team.
