Zero and ultralow-field nuclear magnetic resonance (ZULF NMR) is an NMR modality where experiments are performed in fields at which spin-spin interactions within molecules and materials are stronger than Zeeman interactions. This typically occurs at external fields of microtesla strength or below, considerably smaller than Earth's field. In ZULF NMR, the measurement of spin-spin couplings and spin relaxation rates provides a nondestructive means for identifying chemicals and chemical fragments, and for conducting sample or process analyses.

Self-assembled poly(2-dimethylaminoethyl methacrylate)-poly(2-(diisopropylamino)ethyl methacrylate) (PDMA-PDPA) diblock copolymer nanoparticles are widely employed in biological applications, driving the need for a robust and scalable production method. Although polymerization-induced self-assembly (PISA) enables efficient nanoparticle synthesis at high solids content, its research and application to PDMA-PDPA are limited, likely due to kinetic trapping. Leveraging our recently developed generic time-resolved small-angle X-ray scattering (TR-SAXS) approach for PISA in non-polar media, a reversible addition-fragmentation chain transfer-mediated PDMA-PDPA PISA process in polar solvent that produces spherical micelles is examined.

Modeling membrane interactions with arbitrarily shaped colloidal particles, such as environmental micro- and nanoplastics, at the cell scale remains particularly challenging, owing to the complexity of particle geometries and the need to resolve fully coupled translational and rotational dynamics. Here, we present a force-based computational framework capable of capturing dynamic interactions between deformable lipid vesicles and rigid particles of irregular shapes. Both vesicle and particle surfaces are represented using triangulated meshes, and Langevin dynamics resolves membrane deformation alongside rigid-body particle motion.

Emission factor data for existing heating appliances are being used to estimate achievable emission reductions with emerging heating technologies. However, the emission factors currently being used for modeling were developed prior to low-sulfur fuel standards and rely on a small number of studies, mostly focusing on steady-state operation. In this work, detailed emission measurements of typical heating equipment fired with natural gas and No.

Background: Tackling climate change, together with improving indoor air quality, offers a significant opportunity to improve residents' health and well-being. This requires the evidence base to inform an energy-efficient retrofit design.
Objectives: (i) To develop a protocol that could be implemented by local authorities across a range of housing typologies and (ii) to deploy this protocol to establish baseline conditions in = 30 homes ahead of energy-efficient retrofitting.
