Development of a Lignin-Based Carrier - Citronella Oil Nanoemulsion and Its Utilization as an Herbicide against Specific Weed Species.

This research aims to create an emulsion formulation utilizing lignin as a carrier and citronella oil for its application as a herbicide. The formulation composition includes lignin solution 55-62 %v/v, Tween 80 25 %w/v, propylene glycol 10 %w/v, and citronella oil 3-10 %w/v. The preparation steps involve preparing the oil phase by mixing tween 80 surfactant, propylene glycol, and citronella oil; preparing the aqueous phase by mixing lignin into distilled water at pH 12 with stirring; mixing the oil phase and the water phase accompanied by stirring at 5000-10000 rpm for 1-5 minutes until a stable solution is formed as a natural herbicide.

Preparation and characterization of Arenga pinnata thermoplastic starch/bacterial cellulose nanofiber biocomposites via in-situ twin screw extrusion.

Thermoplastic starch (TPS) is considered as alternative material for substitute petroleum-based materials for single-use packaging material applications. The main weakness of TPS is sensitive to water and humidity which causes low mechanical properties and low thermal resistance. To address this limitation, one can enhance the strength is by incorporating cellulose nanofiber as a reinforcing agent.

Fluid Mechanics of Droplet Spreading of Chitosan/PVA-Based Spray Coating Solution on Banana Peels with Different Wettability.

The spreading behavior of a coating solution is an important factor in determining the effectiveness of spraying applications. It determines how evenly the droplets spread on the substrate surface and how quickly they form a uniform film. Fluid mechanics principles govern it, including surface tension, viscosity, and the interaction between the liquid and the solid surface.

Modification of Physio-Mechanical Properties of Chitosan-Based Films via Physical Treatment Approach.

The premise of this work is the modification of the properties of chitosan-based film for possible use in food packaging applications. The biofilm was prepared via thermal and mechanical treatment through blending polymers with chitosan using Polyvinyl Alcohol (PVA) and loading different types of chemical agents, i.e.

Novel In Situ Modification for Thermoplastic Starch Preparation based on Palm Starch.

Thermoplastic starch (TPS) has three main disadvantages, i.e., poor mechanical properties, low thermal stability and water sensibility.
