Amide additives improve RDC measurements in polyacrylamide.

Residual dipolar couplings (RDCs) provide valuable NMR parameters that can be used for structural calculation and verification. Measuring RDCs requires aligning macromolecules using one of various types of alignment media. Of different alignment media options, stretched or compressed polyacrylamide gels are advantageous due to their chemical stability.

Millimeter wave direct-current transmission and reflection spectral data of some organic photo-responsive materials.

Voltage data acquired after probe signal transmitted through the organic film and reflected off the film surface as a function of 0.36 mW millimeter wave signal frequency in the range 110-160 GHz. Five different organic photovoltaic (OPV) materials and one 95:5 blend produced at 2 spin rates are used.
