Nanostructured lipid carriers (NLCs) have emerged as a promising approach to enhance the stability and bioavailability of volatile bioactive compounds. This study introduces a novel pea protein isolate (PPI)‐stabilized NLC using beeswax as a solid lipid for limonene encapsulation, providing a plant‐based alternative to synthetic emulsifiers. The nanocarriers were prepared via melt emulsification, with an optimized ratio of beeswax‐to‐oleic acid to enhance stability and encapsulation efficiency (EE). Pea protein isolate acted as an emulsifier, enabling precise control over the particle size. The optimal formulation used a beeswax‐to‐oleic acid ratio of 3:1, with 3% pea protein isolate, a hydrodynamic diameter ranging from 120 nm to 155 nm, and a zeta potential below −40 mV, successfully encapsulating more than 70% of limonene. DSC analysis indicated alterations in the crystallinity of beeswax upon the addition of oleic acid, facilitating the incorporation of active compounds as nanostructured carriers. In vitro release studies demonstrated a controlled release profile, suggesting prolonged bioactive retention. These findings underscore the potential of pea protein isolate‐stabilized beeswax‐based NLCs as an innovative and sustainable platform for essential oil encapsulation. Additionally, these findings have promising applications in food preservation, pharmaceuticals, and nutraceuticals, offering a new avenue for enhancing the stability and bioavailability of the bioactive compounds.

Solid polymer electrolyte (SPE) nowadays becomes the key enablers in building structural framework of better electrolytes for all‐solid‐sate lithium‐ion batteries (ASS LIBs). A main question remains how to wisely improve the conductivity of polysaccharides, thus promoting today's transition from fossil fuels to green energy. Herein, development of conductive carboxymethyl chitosan (CMCh) complex involving the synergistic impact of lithium acetate (LiCH₃COO) is proposed. Changes in the surface chemistry of CMCh appear, suggesting a successful functionalization to this chitosan derivative in the presence of LiCH₃COO. Following this, SPE containing 20 wt% lithium acetate optimally demonstrates the highest ionic conductivity equivalent to 5.37 × 10⁻³ S. cm⁻¹. However, salt‐added CMCh has a crystallinity index (Cr.I) of 64.57% and a tensile strength of 4.74 MPa, which is lower than the neat CMCh SPE membrane. The success loading of lithium acetate also results in a rougher surface of CMCh membrane than of its reference. Further, salt‐incorporated CMCh membrane exhibits a reduction in the thermal stability. In addition, eventually, these presented findings underpin potential application of this chitosan derivative for future ASS LIBs.
