Rigid polyurethane foams (RPUFs) were synthesized using exclusively lignin-based polyol (LBP) obtained via the oxyalkylation of kraft lignin with propylene carbonate (PC). Using design experiments methodology combined statistical analysis, formulations optimized to obtain a bio-based RPUF low thermal conductivity and apparent density be used as lightweight insulating material. The thermo-mechanical properties ensuing compared those commercial (RPUF-conv) produced conventional polyol. formulation exhibited (0.0289 W/m·K), (33.2 kg/m3), reasonable cell morphology. Although has slightly lower thermo-oxidative stability mechanical than RPUF-conv, it is still suitable for insulation applications. In addition, fire resistance this foam been improved, its average heat release rate (HRR) reduced by 18.5% burn time extended 25% RPUF-conv. Overall, shown potential replace petroleum-based an This first report regarding use 100% unpurified LBP LignoBoost in production RPUFs.

This study introduces a dendronized pressure-sensitive adhesive, TMPE@Rha, addressing Food and Drug Administration (FDA) concerns about traditional adhesives (PSAs) in transdermal drug delivery systems. The unique formulation, composed of rhamnose, trihydroxypropane, poly(ethylene glycol), significantly enhances cohesion tissue adhesion. Leveraging rhamnose improves intermolecular interactions surface chain mobility, boosting Compared to acrylic adhesive 87-DT-4098, TMPE@Rha shows substantial advantages, with up 5 6 times higher peel strength on porcine wood substrates. Importantly, it maintains strong human skin adhesion beyond 7 days without the typical "dark ring" phenomenon. When loaded diclofenac, exhibits 3.12 greater peeling than commercial alternatives, sustaining for days. Rigorous analyses confirm rhamnose's role increasing interaction strength. In vitro studies microscopy demonstrate polymer's ability enhance loading distribution skin, improving permeability. Biocompatibility tests affirm as nonirritating. summary, establishes new standard PSAs systems, offering exceptional adhesion, robustness, biocompatibility. pioneering work provides blueprint next-generation, highly drug-loaded that meet exceed FDA criteria.
