In addition, the Fe2 þ ion in the organic cage is movable perpendicularly to the molecular plane as implied from the structural variation of haem protein molecules in which an Fe2 þ ion in a porphyrin ring moves on the attachment and detachment of an oxygen molecule23,24. Thus, tuning...
The PEDOT:PSS-coated substrates were subjected to an oxygen plasma for 4 min and then transferred to a nitrogen-filled glove box (O2 <1 ppm, H2O <1 ppm) for subsequent processes. Poly-TPD solutions (in chlorobenzene, 8 mg mL−1) were spin-coated at 2000 r.p.m. for 45...
The addition of cholesterol causes a dramatic decrease in the oxygen transport parameter around the nitroxide moiety of 5-SASL in the l o phase, which at 50 mol% cholesterol becomes 5 times smaller than in the pure ESM membrane in the l d phase, and 2 times smaller than in the pure ...

also observed red shift of the emission peaks of CDs from 440 to 625 nm, which was ascribed to a gradual reduction of bandgap with increasing incorporation of oxygen species into the surface functional groups (Fig. 3d) [111]. The oxygen containing functional group-related defect state emission...

Determine each element in the structure by looking at its chemical formula. For example, carbon dioxide's formula is CO2. Therefore it has one carbon atom and two oxygen atoms. Step 2 Look up each element on the Periodic Table. Note each group, or column number. This reflects how many va...
In addition, since PQD is known to be very sensitive to oxygen or moisture in the air17, it is required to improve the atmospheric stability through the composite with a polymer18,19 or encapsulation20. However, the dispersibility issue of the polymer matrix may have an impact on the ...
The reaction solution was degassed under vacuum at room temperature for 30 min and at 90 °C for additional 30 min to completely remove the hexane, water, and oxygen inside the reaction solution. Then the reaction solution was heated up to 310 °C under argon flow and magnetic ...
