Antibiotics-Coated Gold Nanoparticles to Combat Antimicrobial Resistance
Antimicrobial resistance (AMR) has become an alarming threat to the successful treatment of rapidly growing bacterial infections because of the abuse and misuse of antibiotics. Traditional antibiotics bear many limitations including restricted bioavailability, inadequate penetration and the emergence of antimicrobial-resistant microorganisms. Recent advances in nanotechnology for the introduction of nanoparticles with fascinating physicochemical characteristics have been predicted as an innovative means of defence against antimicrobial-resistant diseases. The use of nanoparticles renders several benefits including improved tissue targeting, better solubility, improved stability, enhanced epithelial permeability and minimal side effects.

Application of Nanosheets in Nanomedicine
The term “nanosheets” has been coined recently to describe supported and free-standing “ultrathin film” materials, with thicknesses ranging from a single atomic layer to a few tens of nanometers. Owing to their physicochemical properties and their large surface area with abundant accessible active sites, nanosheets (NSHs) of inorganic materials such as Au, amorphous carbon, graphene, and boron nitride (BN) are considered ideal building blocks or scaffolds for a wide range of applications encompassing electronic and optical devices, membranes, drug delivery systems, and multimodal contrast agents, among others. In the specific case of nanomaterials applied to medicine (nanomedicine), this multidisciplinary field has captured the interest of researchers and engineers from different disciplines.

Application of Plant Waxes in Edible Coatings
Natural waxes are of plant or animal origin. They are resistant to moisture, oxidation, and microbiological decomposition. Plant waxes of commercial and industrial importance are obtained from various plant species and are used to produce cosmetic products, ink, varnishes, luster, candles, pastels, etc. Some of them are used in the composition of some edible coatings applied to various foodstuffs. By using them, the properties and quality of food products are preserved during storage.

Application of Polysaccharides in Biodegradable Films
Biodegradable films emerge as alternative biomaterials to conventional packaging from fossil sources, which, in addition to offering protection and increasing the shelf life of food products, are ecologically sustainable. The materials mostly used in their formulation are based on natural polysaccharides, plasticizing agents, and bioactive components (e.g., antimicrobial agents or antioxidants). The formulation of biodegradable films from polysaccharides and various plasticizers represents an alternative for primary packaging that can be assigned to specific food products, which opens the possibility of having multiple options of biodegradable films for the same product.

Application of Stretchable Superhydrophobic Surfaces
Superhydrophobic surfaces find extensive applications in various fields, including self-cleaning, liquid manipulation, anti-icing, and water harvesting. To achieve superhydrophobicity, the surfaces are designed with hierarchical nano- and/or microscale protrusions. These structures result in a static contact angle above 150° and a sliding/rolling-off angle below 10° when water droplets deposit on the surface. The combination of hierarchical structures and low-surface energy materials contributes to this unique liquid-repellent property. In addition to liquid repellency, the durability of these surfaces is crucial for practical applications, which has prompted the exploration of stretchable superhydrophobic surfaces as a viable solution. The flexibility of these surfaces means that they are effectively safeguarded against mechanical damage and can withstand daily wear and tear.

Applications of Magnetic Hydrogels
Magnetic hydrogels (MHGs) are a special class of hydrogel that contain at least one magnetic component in their composition. Generally, MNPs are dispersed in a polymer gel matrix to form MHGs. These hydrogels are special because they are prone to show fluctuations in their physical properties in the presence of an externally applied magnetic field.

Applications of Surface Modified by Electrical Discharge Coating
Electrical discharge coating (EDC) process is used to deposit material on workpiece surface from sacrificial or green compact tool electrode in an electrical discharge machine.  Electrical discharge coating is an advanced and simple coating process that is applied for conductive materials due to the certain advantages, i.e., good adhesion among the parent material and coating, high efficiency to achieve thick coating, and ability to balance the composition of coated layer by using proper tool electrode material and dielectric fluid.

Band Gap Engineering
Crystalline TiO2 (as rutile, anatase or brookite) can absorb only about 4% of the solar energy due to its large band gap in the range of 3.0–3.2 eV. As a consequence, the true incident photon conversion yield of most sun-light and semiconductor-assisted photoreactions is low. The aim of exploiting visible light can be achieved by applying various techniques such as doping or modification with metals and non-metals, coupling of semiconductors, or dye sensitization. Since only the former technique seems to allow cost-efficient and robust synthesis routes for realistic applications of titania coatings, this chapter will concentrate on metal and non-metal doping.

Benzil
Benzil (BZ) can be converted almost quantitatively to benzoyl peroxide (BP) in aerated polymer films upon irradiation at >400 nm (i.e., the long-wavelength edge of the n→π* absorption band of BZ, where BP does not absorb).
