The Carbon Mineral Challenge is a worldwide hunt to find new carbon-bearing minerals by 2019. An estimated 145 such minerals remain undiscovered. Both professional and amateur geologists can get involved. This poster shows some recent discoveries:
Listed in the poster are:
- Abellaite, NaPb2(CO3)2(OH), reported this year (photo below)
- Tinnunculite, C5H4N4O3 · 2 H2O
- Marklite, Cu5(CO3)2(OH)6 · 6 H2O
- Middlebackite, Cu2C2O4(OH)2
- Leószilárdite, Na6Mg(UO2)2(CO3)6 · 6 H2O
- Ewingite, Mg8Ca8(UO2)24(CO3)30O4(OH)12 · 138 H2O
- Braunerite, K2Ca(UO2)(CO3)3 · 6 H2O
- Parisite-(La), CaLa2(CO3)3F2

Wash bottles, in one form or another, have been a long-term feature of the chemistry lab. Once they were made of glass, and were operated by blowing. In more recent times, plastic squeeze bottles have been used.

I will be offline for a few weeks. A variety of science-related posts are queued during my absence, but solar-race coverage will be on hold until I return (my WSC team list is up to date as at 23 June). See you all later!
June 21 was an eventful day in solar-car racing. The Belgian team revealed their zippy new car:
Nuon Solar Team set a world record, clocking up 882 km in a 12-hour track session.
Eindhoven have also unveiled their new car, and it’s gorgeous! It lacks the “tunnel” of their previous vehicle, and this allows them to seat a family of five:
The botanist Joseph Dalton Hooker was born 200 years ago, on 30 June 1817. Kew Gardens, of which he was the director, has a special event to commemorate him. Hooker travelled on expeditions to Antarctica, India, Palestine, Morocco, and the Western United States. The pictures below are from his The botany of the Antarctic voyage of H.M. discovery ships Erebus and Terror in the years 1839–1843, under the command of Captain Sir James Clark Ross. He also published several volumes on the botany of India.
The open road is calling teams for the 2017 World Solar Challenge, and JU Solar Team (battery box ready for shipping), Lodz Solar Team (battery box), Nuon Solar Team (world record attempt), Solar Team BE (unveiling Punch 2), and Singapore (dashboard design) are hearing that call.
