Application in Wound Healing
Wound healing requires careful, directed, and effective therapies to prevent infections and accelerate tissue regeneration. In light of these demands, active biomolecules with antibacterial properties and/or healing capacities have been functionalized onto nanostructured polymeric dressings and their synergistic effect examined. In this work, various antibiotics, nanoparticles, and natural extract-derived products that were used in association with electrospun nanocomposites containing cellulose, cellulose acetate and different types of nanocellulose (cellulose nanocrystals, cellulose nanofibrils, and bacterial cellulose) have been reviewed. The impact of these combinations in wound healing are here examined and explored.

Euclidean Graphs as Curvilinear Feature Descriptors
Euclidean graphs are an ideal data structure for the functional description of line-shaped features in digital images such as cracks as they convey both geometrical and topological information about the object path in a compact and integrated format, enabling the development of autonomous, highly tuned algorithms for identification, selection, analysis, comparison and archiving of the identified objects.

Effect of Nanoparticles on Plant Physiological Activity
Due to their unique characteristics, nanoparticles are increasingly used in agricultural production through foliage spraying and soil application. The use of nanoparticles can improve the efficiency of agricultural chemicals and reduce the pollution caused by the use of agricultural chemicals.

Friction Stir Welding of Polymers
Friction Stir Welding (FSW) is one of the welding methods within the category of friction welding, as it uses the friction between the base material and the tool to generate the heat necessary to soften the material of the joint. The FSW process was developed, demonstrated and patented by “The Welding Institute (TWI)” in England for the first time by Thomas et al.. The principle of the conventional process is illustrated in, as well as its main variables.

Methods for Reducing Water Absorption of Composite Materials
Plant fiber reinforced polymer matrix composites have attracted much attention in many industries due to their abundant resources, low cost, biodegradability, and lightweight properties. Compared with synthetic fibers, various plant fibers are easy to obtain and have different characteristics, making them a substitute for synthetic fiber composite materials. In order to address the adverse effects of natural fiber moisture absorption on the mechanical properties and dimensional stability of composite materials, researchers have modified fibers through various chemical and physical methods. The various methods to reduce the water absorption of composite materials such as fiber surface chemical treatment, the use of compatibilizers, fiber mixing, nanofillers, and polymer coatings.

Vitreous Substitute
The ideal vitreous substitute should mimic the native vitreous in terms of both structure and function such as transparency, biocom-patibility, elasticity, easy injectability, except for its liquefication and biodegradability with age. Current vitreous substitutes are used in order to maintain certain criterias such as optical and biomechanical properties and intraocular pressure. Therefore, extensive research with biomaterials is underway taking into consideration its composition, structure and physiological properties as well to overcome the downside of the currently used tamponades.

Properties and Biomedical Application of Chitosan-Based Hydrogels
The prospective applications of chitosan-based hydrogels (CBHs), a category of biocompatible and biodegradable materials, in biomedical disciplines such as tissue engineering, wound healing, drug delivery, and biosensing have garnered great interest. The synthesis and characterization processes used to create CBHs play a significant role in determining their characteristics and effectiveness.

Polymer–Lipid Pharmaceutical Nanocarriers
Some issues in pharmaceutical therapies such as instability, poor membrane permeability, and bi-oavailability of drugs can be solved by the design of suitable delivery systems based on the com-bination of two pillar classes of ingredients: polymers and lipids. At the same time, modern tech-nologies are required to overcome production limitations (low productivity, high energy con-sumption, expensive setup, long process times) to pass at the industrial level.

The Rheological Phase Reaction Method
The term “rheology” stands for the study of a material’s flow behavior under applied deformation forces or stress. The Rheological Phase Reaction (RPR) method is considered a “pollution-less method” to prepare any metal oxides with high crystallinity, phase purity, and fewer agglomerations depending on the proper raw materials and the right temperature conditions are being chosen.

Expanding Monomers
Expanding Monomers are monomers which are increasing in volume (expanding) during polymerization. They can be added to monomer formulations to counteract the usual volume shrinking (during polymerization) to manufacture products with higher quality and durability. Volume Shrinkage is in first line for the unmeltable thermosets a problem, since those are of fixed shape after polymerization completed.:2
