Structural phase transformation of quantum spin liquid herbertsmithite pressure induced enhancement of the cooperative Jahn-Teller effect and antisite disorder.

Herbertsmithite, CuZn(OH)Cl, serves as one of the most promising candidates for quantum spin liquids with a perfect quantum kagome Heisenberg antiferromagnetic system. It can comprise an ideal model system for studying the compression response of the unique structure as well as exotic properties of kagome quantum spin liquid materials, which is of fundamental importance from both scientific and technological viewpoints. In this work, the structural evolution of herbertsmithite was investigated X-ray diffraction and Raman scattering techniques up to 30 GPa.

Interplay between External High Pressure and Intrinsic Jahn-Teller Effect in the Compression Behavior of Clinoatacamite.

Clinoatacamite (γ-Cu(OH)Cl) possesses a geometrically frustrated kagome lattice for the S = 1/2 antiferromagnetic spin system. Thus, it is deemed as the mother compound of many promising quantum spin liquid materials. Here, we synthesized clinoatacamite consisting of homogeneous octahedron-like particles with an average size of 1-2 μm via a hydrothermal strategy.

Interface-Induced Self-Assembly Strategy Toward 2D Ordered Mesoporous Carbon/MXene Heterostructures for High-Performance Supercapacitors.

Two-dimensional transition metal carbonitrides (MXene) have demonstrated great potential in many fields. However, the serious aggregation and poor thermodynamic stability of MXene greatly hinder their applications. Here, an interface-induced self-assembly strategy to synthesize ordered mesoporous carbon/Ti C T heterostructures (OMCTs) was developed.
