A series of poly(pentadecafluorooctyl methacrylate)-block-polyhydroxystyrene (PPDFMA-b-PHS) block copolymers (BCPs) were synthesized via reversible addition-fragmentation chain-transfer polymerization and subsequent deprotection. Because the high incompatibility between hydroxyl groups fluoro groups, interaction parameter (χ) these BCPs, determined by temperature-resolved small-angle X-ray scattering (SAXS), was extremely high. The χ value PPDFMA-b-PHS 0.48 at 150 °C, 16× larger than...
Objectives This study aimed to investigate the relationship between albumin-corrected anion gap (ACAG) and lumbar spine bone mineral density (BMD) in a diverse population, assessing how variations ACAG levels correlate with changes BMD potential implications for osteoporosis risk. Methods A cross-sectional analysis was conducted involving 3,057 participants (1,555 males 1,502 females). Participants were stratified into quartiles based on baseline levels. Demographic clinical characteristics...

Block copolymers with perfluoroalkyl side-chains can self-assemble rapidly at moderate temperatures to yield sub-5 nm domains.
To improve methane storage capacity of porous organic materials, this work demonstrates that a rigid ladder-type backbone is more entropically favorable for gas adsorption and leads to high uptake per unit surface area. A ladder polymer network was designed synthesized as the model material via cross-coupling polymerization subsequent ring-closing olefin metathesis, followed by characterization solid-state nuclear magnetic resonance (NMR) spectroscopy. This exhibited remarkable area, which...
Abstract Supercapacitors have been widely studied as a typical representative of new energy storage systems. As type novel crystalline porous material, covalent triazine frameworks (CTFs) attracted enormous attention owing to their high nitrogen content and unique ring structure, which give them chemical thermal stability. In this paper, 2,4,6‐tris(4‐aldophenyl)‐1,3,5‐triazine (TFPT) 2,4,6‐tris(4‐aminophenyl)‐1,3,5‐triazine (TAPT) were used synthesize TPT‐CTFs by Schiff base reaction....
Global intramolecular hydrogen bonds were installed and manipulated in a rigid artificial synthetic polymer order to actively control its conformation for synthesis processing. The solubility was switched on off by chemically inhibiting regenerating these preorganized bonds. Such active manipulation made it possible synthesize this highly with elevated molecular weights. A well-solubilized, noncoplanar precursor thermally cleavable Boc groups synthesized (Mn = 32.4 kg/mol). After processing...
Conjugated ladder polymers possess multiple-stranded bonds which impart rigidity into their backbones. This can promote π-orbital delocalization for improved electronic and optical properties, or preserve interchain void space to render microporosity. Limited solution processability, however, often impedes practical applications. To address this challenge, nanoparticulated, cross-linked polymer networks were synthesized through miniemulsion polymerization followed by ring-closing olefin...
