Diabetes mellitus, a widespread chronic illness categorized by elevated blood sugar levels, poses a significant health burden. This study aimed to synthesize an optimal oleogel formula and investigate its impact on accelerating diabetic wound healing through a multidimensional approach. The evaluation spanned in vitro examination utilizing bacterial cultures, and in vivo assessments on mice, involving a meticulous 9‐day observation of wound healing percentages. The successful synthesis and characterization of AgNPs and Na‐CMC laid the foundation for further exploration. Oleogel formulation optimization using Response Surface Methodology (RSM) revealed the most effective composition featuring Na‐CMC at 4.5 %, beeswax at 12.5 %, and a stirring temperature of 80 °C. Manufacturing success was affirmed through comprehensive testing encompassing pH, organoleptic properties, dispersion, gelation time, and FTIR analyses. Characteristics of extracted nanoparticles were scrutinized through SEM‐EDX, PSA, and Zetapotential tests. In vitro evaluations showcased the commendable antibacterial activity of AgNPs. Notably, in vivo observations highlighted the superior wound healing capabilities of oleogel ointment enriched with AgNPs. These findings collectively underscore the promising potential of the synthesized oleogel in promoting the healing process for diabetic wounds, validated through diverse analytical approaches, marking a significant stride toward effective therapeutic interventions in diabetes‐related wound management.

“…A broad band observed at 3400 cm −1 is attributed to the hydroxyl groups in phenolic and aliphatic structures [ 26 ]. The C-H stretching appeared at 2900 cm −1 , indicating the present of aromatic methoxyl groups, methyl, and methylene groups [ 19 ]. In the carbonyl/carboxyl region, weak to medium bands were found near 1722 cm −1 .…”

“…Alkaline Lignin was prepared using black liquor, which is a byproduct of the paper manufacturing process, and agricultural residues, by being treated with 1.5 M NaOH at a ratio of 1:10 (residue: NaOH solution) at 70 °C for 120 min according to the kraft method [ 18 , 19 , 20 ]. Organsolv lignin was extracted from four agricultural residues—Alf Alfa, hard date palm fibrillum (HDPF), soft date palm fibrillum (SDPF), and saw dust (S. dust)—by treating them with formic and acetic acids using the Organosolv solution [ 21 ].…”

Modification of Fabrication Process for Prolonged Nitrogen Release of Lignin–Montmorillonite Biocomposite Encapsulated Urea

Crop production faces challenges in achieving high fertilizer use efficiency. To address this issue, slow-release fertilizers (SRFs) have emerged as effective solutions to minimize nutrient losses caused by leaching, runoff, and volatilization. In addition, replacing petroleum-based synthetic polymers with biopolymers for SRFs offers substantial benefits in terms of sustainability of crop production and soil quality preservation, as biopolymers are biodegradable and environmentally friendly. This study focuses on modifying a fabrication process to develop a bio-composite comprising biowaste lignin and low-cost montmorillonite clay mineral for encapsulating urea to create a controllable release fertilizer (CRU) with a prolonged nitrogen release function. CRUs containing high N contents of 20 to 30 wt.% were successfully and extensively characterized using X-Ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). The results showed that the releases of N from CRUs in water and soil extended to considerably long periods of 20 and 32 days, respectively. The significance of this research is the production of CRU beads that contain high N percentages and have a high soil residence period. These beads can enhance plant nitrogen utilization efficiency, reduce fertilizer consumption, and ultimately contribute to agricultural production.

“…In plants, lignin bridges the gap between cellulose and hemicellulose, keeps the lignocellulose matrix together, and functions as an adhesive to provide cell wall strength and rigidity. Herbaceous plants, hardwood, and softwood typically contain 15 to 20%, 20–25%, and 20–30% percent lignin, respectively [ 57 , 58 ]. Wei et al [ 59 ] studied the preparation of a fully degradable flame retardant wood/poly(lactic acid) (PLA) biocomposite (FPW) with low cost and excellent mechanical properties.…”

Research and Application of Biomass-Based Wood Flame Retardants: A Review

Wood is widely used as a construction material due to its many advantages, such as good mechanical properties, low production costs, and renewability. However, its flammability limits its use in construction. To solve the problem of wood flammability, the most common method to improve the fire safety of wood is to modify the wood by deep impregnation or surface coating with flame retardants. Therefore, many researchers have found that environmentally friendly and low-cost biomass materials can be used as a source of green flame retardants. Two aspects of biomass-based intumescent flame retardants are summarized in this paper. On the one hand, biomass is used as one of the three sources or as a flame-retardant synergist in combination with other flame retardants, which are called composite biomass intumescent flame retardants. On the other hand, biomass is used alone as a feedstock to produce all-biomass intumescent flame retardants. In addition, the potential of biomass-based materials as an environmentally friendly and low-cost FR source to produce high-performance biomass-based flame retardants with improved technology was also discussed in detail. The development of biomass-based intumescent flame retardants represents a viable and promising approach for the efficient and environmentally friendly production of biomass-based flame retardants.
