Block copolymers containing thermoresponsive polyN-isopropyl acrylamide (PNIPAM) and a persistently hydrophobic block, like polystyrene (PS), form micellar gels in water when triblock (PS-PNIPAM-PS) are added as they interconnect micelles. Neutron scattering methods utilizing specific deuteration strategies allow one to address the structure and dynamics with a focus on PNIPAM bridging blocks. [...]

The Voigt function is the convolution of a Gaussian and a Lorentzian.We rederive power series for its half width at half maximum for the limitingcases of near-Gaussian and near-Lorentzian line shapes. We thereby provideindependent verification and slight corrections of the expansion coefficients re-ported by Wang et al (2022). [...]
