Go back to the enewsletter Queenstowns popular sk

first_imgGo back to the enewsletterQueenstown’s popular ski field, Coronet Peak, is amping up the snow magic with a new interactive experience called The Ice Slides by Ice Castles.Located next to the main Coronet Express chairlift, the display is within easy walking distance from the base building deck. Guests will be able to race down winding slides encased entirely in ice and perched on a frozen throne. The ice is illuminated at night with colour-changing LED lights which will add to the magic of Coronet Peak’s night skiing on Wednesdays, Fridays and Saturdays.Nigel Kerr, Coronet Peak Ski Area Manager, says the experience is all about sharing the magic of winter, especially with those who don’t ski or snowboard.“The changing country-of-origin mix of New Zealand tourism means more people are attuned to sightseeing all year round, summer or winter. This is part of moving our product mix to appeal to them as well as our regular pass holders who will love the surprise.”Only 20 minutes from downtown, Coronet Peak is one of the most popular sightseeing ski fields in the region, with greater non-ski traffic than nearby Queenstown ski field, The Remarkables, which is 40 minutes from downtown.Ice Castles CEO Ryan Davis said the icy attraction was the first for New Zealand.“We love being able to bring our experience to the Southern Hemisphere. Our team is all about giving more people around the world another way to enjoy the outdoors together, make memories and freeze time with their loved ones.”Utah-based Ice Castles is a seasonal entertainment company that creates elaborate, frozen castles, slides and other structures each winter in six cities across North America.Made entirely of frozen water, the giant structure at Coronet Peak has taken 52 days to build. A crew of six ice artisans from across the United States and Canada have moved to the area to construct the experience.Passes are priced at NZ$35 for 12+ and NZ$29 for 6-11, with 5 and unders admitted for free. Ticket sales are now available to purchase at http://icecastles.com/new-zealand, or with Coronet Peak guest services.It opens at 10am daily, weather permitting.The light display will operate on Coronet Peak’s night ski evenings, running on Wednesdays, Fridays and Saturdays from late July.Go back to the enewsletterlast_img read more

NUST MISIS study demonstrates high toxicity of silver nanoparticles

first_imgJun 6 2018NUST MISIS scientists and their colleagues from the Russian Academy of Sciences (RAS) have proved the high toxicity of silver nanoparticles by conducting an experiment with embryos of Danio fish (Danio rerio). The research results are published in the Journal of Hazardous Materials.Silver is a heavy metal and will have toxic properties in the human body in excessive amounts. The number of silver nanoparticles in commercial products has steadily been growing every year, but scientists around the world are actively exploring their impact on the human body and the environment.Related StoriesInnovative magnetic nanoparticles show potential for PET/MRI bimodal imaging applicationsResearchers exploit nanoparticles to develop test for early detection of different diseasesResearchers develop new nanotheranostic system that solves many problems”The scientific work conducted by the research team from NUST MISIS, led by Professor Leonid Kustov, head of the NUST MISIS Laboratory of Nanochemistry & Ecology, is part of a large international project on the study of models of nanoparticle toxicity. The research of new nanomaterials carried out as part of this project allows scientists to assess their potential toxic effects on living organisms”, — said Alevtina Chernikova, Rector of NUST MISIS.During the study, scientists mixed a solution of silver nanoparticles (water + nanoparticles) with an incubation medium (salt solution for eggs` development), where Danio rerio embryons were put. The scientists then observed the peculiarities of their development and the morphological deviations on a daily basis.According to the authors, both forms of silver nanoparticles demonstrated greater toxicity compared to silver ions (AgNO3). At the same time, the flat silver nanoparticles turned out to be even more toxic than the spherical ones.”The previous studies have explained the toxicity of silver nanoparticles through the presence of silver ions as a result of the partial dissolution of nanoparticles. The results we have obtained allow us to suggest that the toxicity of nanosilver is due to the presence of nanoparticles in samples”, — added Natalia Abramenko.The study’s results expand the existing understanding of the effect of nanoparticle characteristics on their toxicity. According to the scientists, they can be used not only in assessing the risks of the introduction of nanomaterials, but also directly in the preparation of the safest nanoparticles.
