Phase Transition of Lipid Nanoparticles for Drug Delivery
Lipid based nanoparticles effectively transport delicate molecules for therapeutic purposes, protecting them from degradation, increasing their stability in the blood circulation and allowing to convey and release the transported substances in specific areas of the body. The formulation of liposomes, cubosomes and hexosomes can be tuned to obtain pH- or temperature responsive nanoparticles. Understanding the response to such external stimuli is of paramount importance for the design and production of efficient drug delivery systems.

Modified Carbon Nanotubes for Oxygen Reduction Reaction
In order to develop highly efficient and stable catalysts for oxygen reduction reaction (ORR) that do not contain precious metals, it is necessary to modify carbon nanotubes (CNT) and define the effect of the modification on their activity in the ORR.

Glucosinolates (GSs)
Glucosinolates, anionic plant secondary metabolites shared in order Brassicales together with Glucosinolates Hydrolysis Products have recently gained much focus due to their biological activities and mechanisms of action. We reviewed from various scientific databases, the health benefits of GSs/GSHPs, approaches to improve plant contents, their bioavailability, and bioactivity. Findings indicate these compounds (natural, pure, synthetic, and derivatives) play an important role in human/animals (disease therapy and prevention), plant health (defense chemicals, biofumigants/biocides), and food industries (preservatives). Overall, much interest focuses on in vitro studies as anti-cancers and antimicrobials. In plant, GSs/GSHPs improvement utilizes mostly biotic/abiotic stresses and short periods of phytohormones application. Their availability and bioactivity are directly proportional to their contents at the source which is affected by methods of food preparation, processing, and extraction. We, conclude that, to a greater extent, there is a need to explore and improve GSs rich sources, and these should be emphasized to obtain natural bioactive compounds/ active ingredients that can be included among synthetic and commercial products for use in maintaining and promoting health. Furthermore, the development of advanced researches on compounds pharmacokinetics, their molecular mode of action, genetics-based on biosynthesis, their uses in promoting the health of living organisms is highlighted.

Amine Type in CO2 Separation
Efficient CO2 capture technologies such as absorption/adsorption of CO2 sorbents, cryogenic separation, and membrane separation, have been developed experimentally and industrially. Among them, membrane technology is attracting growing attention owing to its inherent advantages that include energy-efficiency, ease of operation and scale-up, and a small footprint.

Epitaxial Graphene on 4H-SiC (0001)
Epitaxial graphene on SiC as a hosting substrate for other materials growth is due to its enhanced reactivity compared to chemically inert free-standing exfoliated graphene. Indeed, numerous experimental results by theoretical predictions indicate that by virtue of its physical and structural properties, epitaxial graphene may contain several different highly reactive regions (step edges, charge-unbalanced electron-hole puddles, strained regions, and edges of bilayer inclusions) that may serve as effective nucleation centres.

Two-Dimensional MoS2
 In recent years, great progress has been made for 2D MoS2 in the field of electrocatalysis, and its exposed unsaturated edges are considered to be active sites of electrocatalytic reactions. In this entry, author focus on the latest progress of 2D MoS2 in the oxygen reduction reaction (ORR) that has not received much attention. First, the basic properties of 2D MoS2 and its advantages in the ORR are introduced. Then, the synthesis methods of 2D MoS2 are summarized, and specific strategies for optimizing the performance of 2D MoS2 in ORRs, and the challenges and opportunities faced are discussed. Finally, the future of the 2D MoS2-based ORR catalysts is explored.

Polyetheretherketone (PEEK) Biomaterial
Polyetheretherketone (PEEK) has become a useful polymeric biomaterial due to its superior properties and has been increasingly used in dentistry, especially in prosthetic dentistry and dental implantology. Promising applications of PEEK in dentistry are dental implants, temporary abutment, implant-supported provisional crowns, fixed prosthesis, removable denture framework, and finger prosthesis. PEEK as a long-term provisional implant restoration has not been studied much.

Surface modification of dental implants
Dental implants are widely used in the field of oral restoration, but there are still problems leading to implant failures in clinical application, such as failed osseointegration, marginal bone resorption, and peri-implantitis, which restrict the success rate of dental implants and patient satisfaction. Poor osseointegration and bacterial infection are the most essential reasons resulting in implant failure. To improve the clinical outcomes of implants, many scholars devoted to modifying the surface of implants, especially to preparing different physical and chemical modifications to improve the osseointegration between alveolar bone and implant surface. Besides, the bioactive-coatings to promote the adhesion and colonization of ossteointegration-related proteins and cells also aim to improve the osseointegration. Meanwhile, improving the anti-bacterial performance of the implant surface can obstruct the adhesion and activity of bacteria, avoiding the occurrence of inflammation related to implants.

Modeling/Performance Analysis of Nanocarbon Interconnects
As the interconnect delay exceeds the gate delay, the integrated circuit (IC) technology has evolved from a transistor-centric era to an interconnect-centric era. Conventional metallic interconnects face several serious challenges in aspects of performance and reliability. To address these issues, nanocarbon materials, including carbon nanotube (CNT) and graphene, have been proposed as promising candidates for interconnect applications.
