Nodeless Superconductivity in Kagome Metal CsVSb with and without Time Reversal Symmetry Breaking.

The kagome metal CsVSb features an unusual competition between the charge-density-wave (CDW) order and superconductivity. Evidence for time reversal symmetry breaking (TRSB) inside the CDW phase has been accumulating. Hence, the superconductivity in CsVSb emerges from a TRSB normal state, potentially resulting in an exotic superconducting state.

Patterned diamond anvils prepared via laser writing for electrical transport measurements of thin quantum materials under pressure.

Quantum materials exhibit intriguing properties with important scientific values and huge technological potential. Electrical transport measurements under hydrostatic pressure have been influential in unraveling the underlying physics of many quantum materials in bulk form. However, such measurements have not been applied widely to samples in the form of thin flakes, in which new phenomena can emerge, due to the difficulty in attaching fine wires to a thin sample suitable for high-pressure devices.

Synthesis, characterisation and photophysical study of alkynylrhenium(I) tricarbonyl diimine complexes and their metal-ion coordination-assisted metallogelation properties.

A series of alkynylrhenium(I) tricarbonyl diimine complexes has been synthesized and characterized. A blue shift of the intense low-energy MLCT absorption band in the visible region was observed upon coordination of Cu(I) or Ag(I). This class of complexes has been found to show rich thermotropic gelation behaviour upon Cu(I) or Ag(I) coordination with their morphology characterized by SEM.

Synthesis and characterization of luminescent rhenium(I) tricarbonyl diimine complexes with a triarylboron moiety and the study of their fluoride ion-binding properties.

A series of alkynylrhenium(I) tricarbonyl diimine complexes with a triarylboron moiety has been synthesized and characterized. The binding properties of the complex toward fluoride ions have been studied using electronic absorption and emission spectroscopy and were further supported by (19)F NMR binding experiments.
