Additive Manufacturing for Antimicrobial Materials
3D Printing, also known as fused filament fabrication (FFF), continues to open new routes to the production of high-performance and complex structures with enhanced properties and dynamic shapes that are unattainable via conventional fabrication methods.

Allosteric GABAA Receptor Modulators
Among the mammalian ligand-gated ion channels, the GABAA receptor family comprises the largest family with subunits encoded by 19 different genes. Some of these undergo alternative splicing, and, thereby, increase the variety. Their endogenous ligand known as the gamma-aminobutyric acid (GABA) has been established as the main inhibitory neurotransmitter in the central nervous system.

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.

Phenolic Compounds of Hop Strobile Extracts
Hop (Humulus lupulus Linnaeus), a perennial plant belonging to the Cannabaceae family, has become a widely grown agricultural plant because it is used for providing bitterness and aroma to beer. Hop originated in Europe and west Asia, and are cultivated in the United States, Germany, Czech Republic, and England. Historically, the flower extracts of hop, commonly known as hops, have been used in traditional medicine for treating human health because of their sedative, anti-inflammatory, antiseptic, and antidiuretic properties. Hops are a dioecious species and unfertilized female inflorescence are commonly called cones (or strobiles). These cones are rich in unique phenolic compounds such as prenylated flavonoids, humulones (α-acids) and lupulones (β-acids).

Pd Nanoparticles
Among transition metal nanoparticles, palladium nanoparticles (PdNPs) are recognized for their high catalytic activity in a wide range of organic transformations that are of academic and industrial importance. The increased interest in environmental issues has led to the development of various green approaches for the preparation of efficient, low-cost and environmentally sustainable Pd-nanocatalysts.

Polyurethanes and Green Chemistry
Polyurethanes are most often called “green” when they contain natural, renewable additives in their network or chemical structure, such as mono- and polysaccharides, vegetable oils, polyphenols, or various compounds derived from agro-waste white biotechnology. The use of these natural substrates is in line with the principles of green chemistry. However, other principles among all 12 can also be used in the production of polyurethanes.

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.

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.

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
