In poly(vinylidene fluoride) (PVDF)-based electrolytes, residual solvents play a crucial role in determining the electrolyte performance. Herein, the influence of various residual solvents on electrolyte properties is investigated through atomistic modeling. It is found that fluorination and reduced molecular volume can facilitate fast ionic diffusion and enhanced cycling stability.

Helical structures are ubiquitous in nature and exhibit fascinating properties. They are inherently chiral, and many rely on hydrogen bonds to stabilize their conformation. Homopolypeptides of the glutamate type form α-helical secondary structures and are considered rigid-rod polymers.

Photopolymerization-based 3D printing is widely used in dental manufacturing due to its precision and customizability. However, printed resin specimens require effective post-washing to remove unpolymerized resin, which is a critical step that affects both their mechanical properties and biocompatibility. A conventional ultrasonic bath may fail to achieve effective post-washing due to solvent contamination by the residual resin, resulting in incomplete cleaning and possible redeposition.

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.

In-situ microemulsion has shown great potential for remediation of dense non-aqueous phase liquids (DNAPLs) contaminated aquifers due to the capacity to enhance DNAPL solubility and mobility. Understanding the pore-scale removal behavior of DNAPL and quantifying proportions of mobilization/solubilization in flushing process are essential to improve remediation efficiency. However, owing to the opacity of aquifer medium, the sand columns commonly used in flushing experiments are hard to reveal the dynamic behaviors and removal mechanism of DNAPLs in aquifer by in-situ microemulsion.

Current methods for evaluating the photostability of pharmaceutical drugs typically separate the irradiation step from the analytical process, making it challenging to observe real-time photodegradation during irradiation. The use of HPLC equipped with UV and/or MS detectors, which are commonly used for quantitative analysis, requires considerable time to establish optimal conditions, and employs organic solvents, which are harmful to both the environment and the analyst. The aim of this study is to investigate the effectiveness of isothermal differential scanning calorimetry (DSC) equipped with a UV probe (photo-DSC) for evaluating the photostability of pharmaceutical drugs in the solid state.
