There is growing interest in the use of bio-based materials as viable alternatives to petrochemical-based packaging. However, practical application films often hampered by their poor barrier and mechanical properties. In this context, cellulose nanofibers (CNFs) have attracted considerable attention owing exceptional biodegradability, high aspect ratio, large surface area. The extraction CNFs from agricultural waste or non-food biomass represents a sustainable approach that can effectively balance cost environmental impacts. functionalization improves economics raw production processes while expanding applications. This paper reviews recent advances nanofibers, including sources, modification, characterization techniques. Furthermore, we systematically discuss interactions with different composites development functional food films. Finally, highlight nanofiber preservation. Due environmentally friendly properties, are promising alternative petroleum-based plastics. aim present latest discoveries exploring future prospects for edible films, thereby encouraging further research field active

Development of Tetramycin-loaded Core-Shell Balls with Hot/Wet-Response Releasing Property for the Control of Bacterial Wilt Disease

Published: Feb. 15, 2024

Ralstonia solanacearum is the pathogen responsible for solanacearum, which soil-borne, infests plant conduits to cause disease.They are not easy control and harmful.Therefore development of a controlled-release agent responsive pathogen's soil temperature moisture conditions could aid in its control. Corn kernel powder used as carrier Tetramycin biopesticide, with various compounds tested bonding.They were then made by extrusion moulding.Temperature wetness components, including Pentaerythritol Tetrastearate, Tetraoleate, Polyethylene Glycol Stearate, Monooleate,are compounded coated onto cores form an intermediate shell layer. Finally, Ethyl cellulose(EC)and Hydroxypropyl methyl cellulose(HPMC) dissolved sprayed outermost layer complete pellet's layer.After evaluation texture performance test,DSC analysis,TG test,temperature humidity response test, well pellet cross-section SEM observation, field effectiveness etc., preferred formulations screened.The results showed that Core formulation:Corn powder:Tetramycin aqueous:Xanthan gum mass ratio=13.5:23:2; Intermediate Shell layer:PETS: PETO: PEG400MO ratio=10:30:10; Outer layer: cellulose (EC):Hydroxypropyl (HPMC) ratio=5:1.Under high incidence i.e., sustained warmth (30-35℃) (30% content), formulated pills release rate 95.18% 96.24% over period 35 days. Moreover, they stepwise cyclic process under alternating warm humid-dry cold conditions.In tests on tobacco, relative preventive efficacy 54.74% was achieved 106 days post-transplanting. Soil bacterial community structure analysis revealed significant decrease (2.28-2.84 times) abundance Solanaceae Raelia treatment compared Additionally, fungal highter consistency initially across depths, diversity differences between layers reestablished later (106 days), while predominant categories bacteria fungi remained unchanged.In this study, we successfully developed nucleoshell-type slow-controlled pill embedded Tetramycin. This effectively responded changes, resulting disease prevention.This holds promise improving drug utilization easing application challenges, offering broad prospects prevention agriculture.

Poor management of plastic waste leads to environmental pollution, a problem that has been tackled by introducing biodegradable containing bioactive compounds, as an alternative traditional plastics. This research investigated the effects different solvents (water or ethanol) and ultrasonic extraction conditions (ultrasonic power: 30 %, 60 90 %; times: 15 min) on physical functional properties dechlorophylled Cha-Kram leaf extract powder (DCKLEP). The highest antioxidant activities were extracted using % power min time (60 DCKLEP-alc min). In addition, concentrations (0, 0.375, 0.75, 1.5, 3 %) attributes gelatin films evaluated. results indicated increasing concentration significantly (p < 0.05) enhanced thickness, mechanical thermal properties, light barrier film. structure film was modified due interactions between min, confirmed FTIR analysis. UV–visible property improved in Thus, could potentially serve environmental-friendly, active

Investigation of the antimicrobial properties of temperature-sensitive hydrogel containing silver sulfadiazine against various bacterial strains

International Journal of Nanoelectronics and Materials (IJNeaM), Journal Year: 2025, Volume and Issue: 18(1), P. 54 - 61

Published: Jan. 14, 2025

In burn wound management, infection poses a significant challenge, accounting for 75% of deaths in patients. Silver sulfadiazine is broadly used as an effective antibacterial agent treating burns. Numerous researchers have explored various dosage forms silver sulfadiazine, such cream, ointment, topical spray, and hydrogel, antimicrobial applications. Hydrogels offer appealing advantages over conventional drug delivery systems due to their sensitivity responsiveness stimuli, particularly temperature. Nevertheless, the comprehensive investigation properties temperature-sensitive hydrogel containing against different bacterial strains remains lacking. Thus, main objective current study explore incorporating colonized wounds. To assess activity inhibition zone diameters were measured types Gram-positive (Staphylococcus aureus, Enterococcus faecalis, faecium, Streptococcus pyogenes) Gram-negative (Escherichia coli Klebsiella pneumoniae). The synthesized sulfadiazine-loaded exhibited remarkable efficacy these bacteria. Notably, there was no difference diameter between positive control (p>0.05). These findings affirm that holds promise medium, demonstrating excellent
