Two-dimensional (2D) ternary chalcogenides have attracted great attentions because of their novel chemical and physical properties arising from the synergistic effect stoichiometric variation with additional third element compared binary counterparts. Here, high-quality 2D tantalum nickel selenide (Ta2NiSe5) nanosheets are successfully fabricated by a liquid-phase exfoliation (LPE) method. The ...

Abstract In this research, a diode‐pumped SnS 2 passively Q‐switched (PQS) V‐type Tm‐doped pulsed laser was demonstrated. The continuous‐wave (CW) condition without saturable absorber (SA) investigated first. A maximum output power of 1.26W with slope efficiency 24.28% derived at an absorbed pump 7.11W under coupling 5%. With the as‐prepared SA employed, series stable (QS) pulse trains were suc...

Quorum sensing (QS) is a cell density-dependent system of bacterial communication used by several species for triggering a coordinated response when the population reaches a given cell density threshold. Basically, the QS regulatory circuits are formed by two elements, one signal molecule that is constantly produced, and a transcriptional regulator, which activity depends on the presence of a g...
