Take part in our reader survey By 2014-11-27T00:00:00+00:00 Simplified synthesis of a known supercapacitor produces a dough-like material with surprising energy-storing abilities Materials scientists at Drexel University have discovered a new method for making the material that is used in the electrodes of energy storage devices like batteries and super capacitors is not only easier and safer to produce than current electrode material A conductive clay made by US researchers might provide a novel way of storing energy that could, one day, surpass batteries safer and simpler method to make supercapacitors tripling the amount of electric energy they can store Production of the material should be easy to scale-up too who is part of the team that developed the new capacitor synthesis In 2011 Gogotsi and colleagues discovered an entirely new family of two-dimensional supercapacitors MXenes – M being a transition metal and X carbon or nitrogen The cheap material can store three times as much energy as standard carbon capacitors MXene synthesis required hydrofluoric acid ‘You don’t need to be a materials chemist to know that HF is pretty nasty stuff,’ says Gogotsi Gogotsi’s team have developed a simpler and safer protocol to make MXenes using only dilute hydrochloric acid and lithium fluoride The team was surprised to find that when the known MXene titanium carbide was synthesised using this method it stored three times as much energy as the same material made by HF etching or six times as much as ordinary carbon capacitors ‘A somewhat unexpected result,’ admits Gogotsi ‘We have two explanations for this: firstly we do less damage to the MXene sheets when we use milder etchants so the quality of the material produced is higher intercalation [of cations and water] during the synthesis opens up the material’s layers so ions can penetrate more easily into the material The improved supercapacitor recipe produces a soft clay that can be rolled out like biscuit dough The improved MXene was surprising in another way: it was soft like clay thanks to water in-between the material’s sheets The team could mould it into different shapes and rolled it into thin sheets like biscuit dough Materials chemist Milo Shaffer from Imperial College London ‘Previously there’s been a lot of work that used aggressive etchants but this is a very attractive process where you end up with a clay-like paste that can be plastically formed in whatever shape you like,’ he says Other supercapacitor materials like ruthenium oxide beat MXenes when it comes to energy storage; however the materials are available in large quantities and can be used on large scale,’ explains Gogotsi His team is now working on MXenes other than titanium carbide which ‘is not necessarily the best performing one’ ‘The new method also allows us to make some MXenes we could not make before and it leads to different properties [in the known materials] We have a large group of materials to explore Shaffer thinks capacitor–battery hybrids might be another option for energy storage ‘Wherever you need to do some power management you may benefit from having a combination of a capacitor and a battery Another question might be if you could ever make a capacitor behave more like a battery People are already working on various hybrid approaches for example supercapatteries,’ he explains M Ghidiu et al, Nature, 2014, DOI: 10.1038/nature13970 Site powered by Webvision Cloud Ahead of tonight’s finale, KBS2’s “Love Song for Illusion” has unveiled new stills previewing the conclusion a fallen royal descendant who becomes an assassin to avenge her family but inadvertently ends up becoming the crown prince’s concubine The newly released stills capture Ak Hee as well as Sajo Hyun and Yeon Wol in the “chamber within the heart.” Yeon Wol is sleeping and unmoving as if she is dead in Ak Hee’s embrace while Sajo Hyun watches the two with an expression of great grief Viewers are curious to find out how Yeon Wol will be able to enter the chamber and what situation will occur between Ak Hee and Sajo Hyun Ak Hee explodes with the desire to win over Yeon Wol’s heart and even though Sajo Hyun has yet to perfectly regain his memories Viewers are particularly intrigued about how the final showdown between the two alter egos will play out we will showcase the conclusion of the grand narrative that encompasses the past episodes and we will simultaneously satisfy viewers with endless twists and development with no room for rest,” asking viewers to tune in to find out the conclusion of the love triangle between Sajo Hyun The finale of “Love Song for Illusion” will air on February 27 at 10:10 p.m Source (1) Yoon Shi Yoon has officially joined the cast of “Work Later “[Yoon Shi Yoon] will appear in season 2 of ‘Work Later Drink Now’ and is currently filming.” Yoon Shi Yoon made a brief cameo as “Mr Nice Paper,” who met up with Kang Ji Goo on Christmas The upcoming season will feature a continued love line between the pair Are you looking forward to seeing Yoon Shi Yoon in the next season of “Work Later Watch Yoon Shi Yoon in “You Raise Me Up” with English subtitles below Source (1) The fate of Prague's Christmas markets for the 2020-21 season remains unknown due to the current COVID-19 epidemic in the Czech Republic but a Christmas tree for Old Town Square has already been selected Prague's Old Town Square will be adorned with a 19-meter-tall Norway Spruce harvested from private land in Jílové The spruce was selected by tips from locals through Trhy Praha's Christmas tree tips competition which awards 10,000 CZK to a lucky winner if a tree they spotted ends up being used as OId Town Square's Christmas tree "The Norway spruce we have selected this year is beautifully grown and easily accessible by heavy machinery," Taiko Chief Operating Officer Petr Hozák states in a press release "Another advantage is that it is located not far from Prague The private owner contacted us with a tip." it's unclear if Prague's Christmas markets will even take place this year New restrictions announced yesterday will close down numerous venues that provide culture and leisure activities while restrictions on both indoor and outdoor events remain in place While the Christmas markets may not be classified as an event Wenceslas markets a week early due to COVID-19 concerns Taiko is currently awaiting further regulations from the Czech government regarding the COVID-19 epidemic and will negotiate on possible outcomes with the city of Prague The company aims to have a final decision on the fate of the markets by the end of October as it will no longer be possible to plan for them after this date Prague's Christmas markets are tentatively slated to operate from about November 26 Your morning coffee deserves a great companion.
