A red-emitting BODIPY-based fluorescent-resonance-energy-transfer (FRET) molecular probe 1 for selective detection of cysteine and homocysteine was designed. The fluorescence OFF–ON switch is triggered by cleavage the 2,4-dinitrobenzensulfonyl (DNBS) unit from fluorophore thiols. FRET energy donor (λabs = 498 nm, λem 511 nm) a parent BODIPY moiety acceptor based on 4-hydroxylstyryl 568 586 nm). unique C–C linker between established using Suzuki cross-coupling reaction. polyether chain also...
An OFF-ON red-emitting phosphorescent thiol probe is designed by using the 3MLCT photophysics of Ru(II) complexes, i.e., with as electron donor. The non-luminescent because MLCT corrupted transfer from to an intramolecular sink (2,4-dinitrobenzenesulfonyl). Thiols cleave sink, and re-established. Phosphorescence at 598 nm was enhanced 90-fold, a 143 (5256 cm−1) Stokes shift 1.1 μs luminescent lifetime.
Two highly selective OFF–ON green emitting fluorescent thiol probes (1 and 2) with intense absorption in the visible spectrum (molar extinction coefficient ε is up to 73 800 M−1 cm−1 at 509 nm) based on dyads of BODIPY (as electron donor photo-induced transfer, i.e.PET) 2,4-dinitrobenzenesulfonyl (DNBS) acceptor PET process) were devised. The single crystal structures two determined. distance between (BODIPY fluorophore) probe 2 larger than that 1, as a result contrast ratio (or efficiency)...

Free-standing MoS<sub>2</sub>/NiCoS heterostructure nanosheets act as a bifunctional electrocatalyst for overall water splitting in 1.0 M KOH.
Construction of an efficient bifunctional electrocatalyst through a rational interface-engineering strategy to optimize the adsorption energy H* and OH* species at atomic/molecular level is great importance for water splitting. Although conventional NiFe layered double hydroxide (LDH) shows excellent performance alkaline oxygen evolution reactions (OERs), it extremely poor activity toward hydrogen (HERs) due weak sluggish kinetics. In this work, integration sub-nanoscale Ru with LDH can...

Increasing the density in a tokamak is limited by so-called limit, which generally performed as an appearance of disruption causing loss plasma confinement, or degradation high confinement mode could further lead to H → L transition. The L-mode and H-mode limit has been investigated EAST tokamak. Experimental results suggest that limits be triggered either edge cooling excessive central radiation. cooling, leads current profile shrinkage then destabilizes 2/1 tearing mode, ultimately...
