ASACUSA 超流体氦 物质-反物质原子 混合
2023/5/26
A hybrid matter--–antimatter helium atom containing an antiproton, the proton’s antimatter equivalent, in place of an electron has an unexpected response to laser light when immersed in superfluid hel...
Up,Up and Away:USU Chemists say 'Yes,'Helium Can Form Compounds
USU Chemists Helium Can Form Compounds
2017/2/16
Can helium bond with other elements to form a stable compound? Students attentive to Utah State University professor Alex Boldyrev’s introductory chemistry lectures would immediately respond “no.” And...
Although helium is the second most-abundant element (after hydrogen) in the universe, it doesn’t play well with others. It is a member of a family of seven elements called the noble gases, which are c...
The US must stop selling off its helium reserves so that the country has enough of the gas to meet the needs of researchers and medical programmes. That is the view of a new report, Selling the Nation...
To the adrenaline junkie midway through a bungee jump, gravity must feel like it can accelerate matter at a spectacular rate. At the atomic scale, however, when it comes to shifting around neutral par...
