WebCrystal structures of most HTSCs can be obtained by stacking perovskite, rock salt and/or fluorite structure along the c-axis.As an example, Figure 1 shows the orthorhombic YBa 2 Cu 3 O 7−δ unit cell. Other families of HTSCs can be constructed in a similar way. The CuO chains are unique to YBa 2 Cu 3 O 7−δ; however, the most important features of the … Web2 days ago · By David Nield. A time and light illustration designed by one of the researchers. (Viktar Asadchy) Scientists are still getting to grips with the ins and outs of strange materials known as time crystals; structures that buzz with movement for eternity. Now a new variety might help deepen our understanding of the perplexing state of matter.
