Gallate-Based Metal–Organic Frameworks
Within three decades of fundamental findings in research on metal–organic frameworks (MOFs), a new family of hybrid materials known as gallate-based MOFs, consisting of metal salt and gallic acid, have been of great interest. Due to the fact that gallic acid is acknowledged to display a range of bioactivities, gallate-based MOFs have been initially expended in biomedical applications. Recently, gallate-based MOFs have been gradually acting as new alternative materials in chemical industrial applications, in which they were first reported for the adsorptive separation of light hydrocarbons. These porous materials have a bright future and can be kept in development for variety of applications in order to be applied in real industrial practices.

3D-Printed Satellite Brackets
Brackets are the load-bearing components in a satellite. The current age of satellites comprises specific brackets that set out as a link between the bodies of the satellite, reflector parts, and feeder facilities mounted at its upper end. Brackets are used to carry loads of the satellite body frame, supporting elements, batteries, and electronic goods. Additive Manufacturing (AM) is a process in which a 3D solid object is built by adding the material layer-over-layer. The success of making the product using AM technology requires greater experience in Design for Additive Manufacturing (DFAM) which makes use of the design of freedom of AM. Owing to the various advantages of AM and DFAM, it is easy to create high strength-to-weight ratio products. This is an important contribution to aerospace industries in meeting the unabated demand for lightweight and strong structural applications.

Antifoaming Agent for Lubricating Oil
In the process of using lubricating oil, it is inevitable that bubbles will be produced, which can not only accelerate the oil’s oxidation and shorten the oil change cycle but also reduce its fluidity and lubricity, aggravate the wear of mechanical parts and produce an air lock that interrupts the oil pump supply and causes an oil shortage accident.

Steel for Nuclear Pressure Vessels
The nuclear reactor pressure vessel is an important component of a nuclear power plant. It has been used in harsh environments such as high temperature, high pressure, neutron irradiation, thermal aging, corrosion and fatigue for a long time, which puts forward higher standards for the performance requirements for nuclear pressure vessel steel.

Nanoparticles-Loaded Hydrogel System
Hydrogels are three-dimensional porous structures produced with hydrophilic polymers through physical or chemical cross-linking methods and can be prepared from a wide range of natural and synthetic polymers. Nanoparticles (NPs) are colloidal structures designed and produced to transport drugs across biological barriers. Their optimal size range is approximately between 100 and 200 nm. They protect drugs from degradation, increasing their half-life, improving drugs’ bioavailability, and providing a sustained and localized release.

PbS Quantum Dots
Quantum dots are very interesting materials for different opto-electronic applications.  Among the different quantum dots available, semiconductor quantum dots of PbS became very popular and are extensively studied. This chapter focuses on the current understanding of the superlattice formation process induced via self-assembly of PbS quantum dots as probed by the Grazing incidence small angle X-ray scattering techniques (GISAXS/GIWAXS).

Zeolite/Pharmaceuticals System
Zeolites belong to aluminosilicate microporous solids, with strong and diverse catalytic activity, which makes them applicable in almost every kind of industrial process, particularly thanks to their eco-friendly profile. Another crucial characteristic of zeolites is their tremendous adsorption capability. Therefore, it is self-evident that the widespread use of zeolites is in environmental protection, based primarily on the adsorption capacity of substances potentially harmful to the environment, such as pharmaceuticals, pesticides, or other industry pollutants. On the other hand, zeolites are also recognized as drug delivery systems (DDS) carriers for numerous pharmacologically active agents. The enhanced bioactive ability of DDS zeolite as a drug carrying nanoplatform is confirmed, making this system more specific and efficient, compared to the drug itself. These two applications of zeolite, in fact, illustrate the importance of (ir)reversibility of the adsorption process.

Carbon Dots
Carbon dots (CDs) are part of the nanocarbon family including quasi-spherical nanoparticles with sizes around 10 nm. They consist of amorphous and crystalline parts, mainly composed of carbon with a fringe spacing of 0.34 nm, which corresponds to the (002) interlayer spacing of graphite. Since their first discovery in 2006, CDs have gained ever-increasing attention due to their fascinating properties like distinctive optical behaviour, tunable emission, different functional groups, good biocompatibility, chemical and photo-stability, low toxicity, and low-cost production. More importantly, CDs properties can be changed by controlling their size, shape, and heteroatom doping and by modifying the surfaces. They are considered promising Green alternatives to traditional fluorescent dyes and have been proposed for different optoelectronic applications such as sensing, bioimaging, fingerprint detection, gene delivery, solar cells, or printing inks
