A Fluorescent Rotaxane: Molecular Shuttle and Sensor Gel
The fluorescent rotaxane is a molecular shuttle sensitive to temperature, pH, and solvent polarity changes. It forms a gel which changes its fluorescence properties upon acidic/basic gas exposure and can be turned into a liquid by shaking, heating, and by adding anions.
Grain boundary segregation energy of phosphorus in 12Cr1MoV steel
Equilibrium grain boundary segregation of P in 12Cr1MoV steel after aging of 15 h under elastic stress of 30 MPa equals nearly to that after thermal aging.
