Biopolymer Materials
Biopolymers are an emerging class of novel materials with diverse applications and properties such as superior sustainability and tunability. Biopolymers pose another option for novel energy material applications. Biopolymers are biodegradable macromolecules composed of repeating units. Natural biopolymers are derived from living matter, such as proteins, polysaccharides, and nucleic acids.

Hydraulic Powered Soft Actuators
Soft actuators have received extensive attention in robotics and smart device applications due to their distinctive dexterity and compliance. Among them, hydraulic soft actuators play an important role in the area because they have much higher specific power and power density than other types such as pneumatic soft actuators. Nevertheless, the deformation of flexible materials in soft actuators brings about inherent hysteresis and nonlinearity, which severely hinders them from producing the desired movement in the presence of advanced control strategies.

Dissociation
Dissociation in chemistry and biochemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner. For instance, when an acid dissolves in water, a covalent bond between an electronegative atom and a hydrogen atom is broken by heterolytic fission, which gives a proton (H+) and a negative ion. Dissociation is the opposite of association or recombination.

Metal (Mo, W, Ti) Carbides for Dry Reforming
Dry reforming of hydrocarbons (DRH) is a pro-environmental method for syngas production. It owes its pro-environmental character to the use of carbon dioxide, which is one of the main greenhouse gases. Transition metal carbides (TMCs) can potentially replace traditional nickel catalysts due to their stability and activity in DR processes.

Safe Nanoparticles
The field of nanotechnology has grown over the last two decades and made the transition from the benchtop to applied technologies. Nanoscale-sized particles, or nanoparticles, have emerged as promising tools with broad applications in drug delivery, diagnostics, cosmetics and several other biological and non-biological areas. These advances lead to questions about nanoparticle safety. Despite considerable efforts to understand the toxicity and safety of these nanoparticles, many of these questions are not yet fully answered. Nevertheless, these efforts have identified several approaches to minimize and prevent nanoparticle toxicity to promote safer nanotechnology.

Periodontitis Treatment
Fabrication of biomaterial that mimics a suitable biological microenvironment is still a major challenge in the field of periodontitis treatment. Hence, in this report, we presented for the first time the fabrication of a novel biomaterial 3D matrix using collagen combined with sodium alginate and titanium oxide (TiO2) to recreate the in-vivo microenvironment and to act as a platform for the culture of human periodontal ligament fibroblasts (HPLF) towards osteogenic differentiation.

The Perovskite Solar Cell
Perovskite, an organic–inorganic hybrid material, tends to be a promising light-harvesting material. PSCs (organic-inorganic perovskite solar cells) are considered a significant breakthrough in photovoltaics and have received great attention. Due to the inherent advantage of perovskite thin films that can be fabricated using simple solution techniques at low temperatures, PSCs are regarded as one of the most important low-cost and mass-production prospects.

Skin Photoprotection by Polyphenols
Polyphenols are phytochemicals with proven antioxidant and antiinflammatory properties. Premature aging and UV-induced skin conditions could be better overcome by topical polyphenols nanoformulations. Further, polyphenols nanoformulations can be of great interest for the cosmetic industries and any individuals who want to improve their skin appearance. Examples in this regard are provided and the potential toxicity issues related to the use of nanomaterials are highlighted.

Antimony/Bismuth Chalcohalides
Despite their comparable performance to commercial solar systems, lead-based perovskite (Pb-perovskite) solar cells exhibit limitations including Pb toxicity and instability for industrial applications. To address these issues, two types of Pb-free materials have been proposed as alternatives to Pb-perovskite: perovskite-based and non-perovskite-based materials. In this entry, we briefly introduce the crystal, energy band structures and theoretical insights of Sb/Bi chalcohalides as solar abosrbers.
