This review provides a comprehensive analysis of techno-economic and life-cycle assessments (TEA and LCA) for biomass thermochemical conversion processes that yield gaseous fuels such as syngas, hydrogen, and methane. The study analyzes core issues, including the influence of feedstock diversity, technological maturity, major cost factors, carbon reduction potential, and environmental outcomes of thermochemical conversion approaches.

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). [...]
