This research creates a non-fluorinated, superhydrophobic coating inspired by the hierarchical structure of the Taro leaf, utilizing an emulsion of alkyl ketene dimer (AKD, as secondary roughness) encapsulated within cellulose nanofibres (CNFs), assembling with cellulose microparticles (CMPs, as primary roughness) and TiO2 nanoparticles (as tertiary roughness). The post-recrystallization of AKD plays a vital role in the formation of multi-level surface roughness. Attributing to the driving force generated by water evaporation, the orientation of recrystallized AKD can be regulated either parallel or perpendicular to the substrate. The coated paper exhibited a water contact angle (WCA) of 166.7 ± 3.2° on unsized paper and up to 173 ± 2.0° on filter paper. Cooling temperature and cooling rate play a crucial role on the formation of uniform and stable platelet structures according to the morphology analysis of AKD's recrystallization. Due to the strong superhydrophobicity and the incorporation of TiO2 nanoparticles, the coating possesses self-cleaning and anti-fungal qualities, successfully preventing tomatoes from rotting. In short, this research presents a sustainable approach for the production of aqueous-phase coatings, with potential applications in waterproof surfaces and food packaging.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"358 ","pages":"Article 123493"},"PeriodicalIF":10.7,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143687927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, detailed structural and functional insights into THPs remain limited. Here, a novel pectic polysaccharide (STHP4) with an average molecular weight (Mw) of 119 kDa was extracted and purified from the aboveground part of <em>T. hemsleyanum</em>. Structurally, STHP4 was mainly composed of galacturonic acid, glucuronic acid, and galactose, with minor glucose, rhamnose, arabinose, and mannose, and its primary backbone was 1,4-GalA. Pectinase treatment of STHP4 yields two distinct fractions: STHP4-1 and STHP4-2. STHP4-1 shared the same types of monosaccharides with STHP4, except for the absence of glucose, but had a broad Mw distribution (9.9 to 251 kDa). Another product, STHP4-2, a mixture of oligosaccharides and free monosaccharides, has a Mw of 1.387 kDa. Their structures were further elucidated via methylation analysis and NMR spectra. Furthermore, STHP4-1 exhibited superior immune regulatory effects on macrophages, including increased nitric oxide release and elevated interleukin-6, interleukin-1β, and tumor necrosis factor α expression. These findings suggest that STHP4-1 might be the core active domain of STHP4, and both STHP4 and STHP4-1 are potential immune enhancers.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"357 ","pages":"Article 123502"},"PeriodicalIF":10.7,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143628647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chitosan, valued for its biocompatibility and biodegradability, is widely used in hydrogel preparation. However, chitosan derived from <em>Periostracum Cicadae</em> (“Chantui”) has not been explored for creating antibacterial-oriented hydrogels. In this study, we successfully developed a <em>Periostracum Cicadae</em> chitosan-based oriented hydrogel (O-CH) using an electro-assembly method. The O-CH hydrogel exhibited superior hemostatic performance and mechanical strength, with stress levels 7.6 times higher than those of traditional alkali-neutralized hydrogels. Subsequently, silver nanoparticles (AgNPs) were formed <em>in situ</em> on the O-CH hydrogel without the need for additional reducing agents or stabilizers, yielding O-CH@Ag20, which exhibited excellent biocompatibility and enhanced antibacterial properties. In an <em>S. aureus</em>-infected full-thickness rat skin defect model, O-CH@Ag20 reduced bacterial counts at the wound site by 6-fold compared to the gauze group on day 3 and achieved a 97 % wound healing rate by day 10, <em>versus</em> 75 % in the gauze group. Histological analysis revealed that O-CH@Ag20 regulated angiogenesis, collagen deposition, and fibroblast differentiation into myofibroblasts, thereby accelerating wound contraction during remodeling.

Moreover, the presence of low concentrations of NaCl (15 mM and 30 mM) was found to enhance complex formation within these regions, while higher concentrations (50 mM) inhibited complexation. Additionally, when the mass ratio of WPI to Glu was 1:2, the binding sites between the two molecules became fully saturated. Any deviation from this ratio, resulted in a reduction in the number of complexes formed within the defined phase regions. Finally, the composition of the upper and bottom phases in the insoluble complex region (phase separation region) was studied. At pH 4.5, when the ratio of WPI to Glu was 1:4, it was found that 77 % of β-Lg and 76 % of α-La were partitioned into the bottom and upper phases, respectively.
