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

Abstract
Pressure-sensitive adhesives (PSAs) made from norbornene-functionalized terpenoid-based monomers are reported as a possible alternative to the conventional petrochemically based PSAs. For this, tetrahydrogeranyl, menthyl, and isobornyl norbornenate monomers, with a renewable carbon content up to 72%, are synthesized and copolymerized via ring-opening metathesis polymerization (ROMP) with cyclooctadiene and 5-norbornene-2-carboxylic acid. ROMP enables a much faster and controlled polymerization process in comparison to free radical polymerization techniques when targeting high molecular weights and therefore unlocks a potential to design a unique class of PSA materials. The moduli at bonding and debonding frequencies of the obtained PSAs are plotted in the Chang classification system and are used to predict their adhesive performance. Tack and peel measurements indicate that the terpenoid-based norbornenate formulations show similar adhesive properties in comparison to the previously investigated acrylic counterparts.

Abstract
The conversion of lignocellulosic biomass into various high-value chemicals has been a rapid expanding research topic in industry and agriculture. Among them, alkaline removal and utilization of lignin are important for the accelerated degradation of biomass. Modern biorefinery has been focusing the vision on the advancement of economical, green, and environmentally friendly processes. Therefore, it is indispensable to develop cost-effective and simple biomass conversion technologies to obtain high-value products. In this study, the black liquor (BL) obtained from the alkaline pretreatment of biomass was added to polyvinyl alcohol (PVA) solution and used to prepare degradable ultraviolet (UV) shielding films, achieving direct and efficient utilization of the aqueous phase from alkaline pretreatment. This method avoids the extraction step of lignin fraction from black liquor, which can be directly utilized as the raw materials of films preparation. In addition, the direct use of alkaline BL results in films with similar UV-shielding properties, higher physical strength, and similar thermal stability compared with films made by commercial alkaline lignin. Therefore, this strategy is proposed for alkaline-pretreated biorefineries as a simple way to convert waste BL into valuable products and partially recover unconsumed sodium hydroxide to achieve as much integration of biomass and near zero-waste biorefineries as possible.
