From clarifying muddy water to controlling body odour and treating minor shaving cuts, fitkari has many traditional uses.

Physicists have discovered a strange new state of quantum matter in which ultracold atoms defy familiar organizational rules, forming a highly excited yet surprisingly orderly configuration called a ...

Laboratory experiments at 200 MPa show that hydrothermal tourmaline begins forming when fluid B₂O₃ exceeds ...

量子材料中的集体行为可以产生仅携带其组成单元部分量子数的激发。一个显著的例子出现在自旋为1的单元链中，其中拓扑能隙保护链的内部，而自旋为1/2的态——即构成链的单元自旋的一半——出现在末端。在短链中，这些分数化边缘自旋相互耦合，其拓扑保护使其对于混合自旋—超导器件具有吸引力。然而，这种分数化能否在超导凝聚体附近存活，仍是一个未决问题。 研究者在近邻化的Au（111）/Nb（110）衬底上生长了由反 ...
