This report provides an overview of the use of phosphaalkenes (CP) in syntheses of various complexes. Going through successive complexes containing the d-block metals, we sought how this area of chemistry was formed over the years. Additionally, this work contains information on the possible coordination types and means of constructing the complexes. In addition, this review reveals the reactivities of phosphaalkene complexes with a strong emphasis on catalytic properties.

“…TiO 2 NPs are of considerable interest because of their low cost, high stability, photocatalytic activity, and reusability. − Therefore, TiO 2 NPs have been adapted for nearly a century in various industrial and consumer products, including paints, adhesives, rubbers, plastics, sunscreens, and catalysts. − The FDA has approved the safety of TiO 2 as a color additive in food, drug cosmetics, and personal care items, such as toothpaste. TiO 2 NPs are commercially used as coloring agents to produce toothpaste with a white color .…”

Whitening agents, such as hydrogen peroxide and carbamide peroxide, are currently used in clinical applications for dental esthetic and dental care. However, the free radicals generated by whitening agents cause pathological damage; therefore, their safety issues remain controversial. Furthermore, whitening agents are known to be unstable and short-lived. Since 2001, nanoparticles (NPs) have been researched for use in tooth whitening. Importantly, nanoparticles not only function as abrasives but also release reactive oxygen species and help remineralization. This review outlines the historical development of several NPs based on their whitening effects and side effects. NPs can be categorized into metals or metal oxides, ceramic particles, graphene oxide, and piezoelectric particles. Moreover, the status quo and future prospects are discussed, and recent progress in the development of NPs and their applications in various fields requiring tooth whitening is examined. This review promotes the research and development of next-generation NPs for use in tooth whitening.

“…143,191 In addition, the ripening effect significantly lowers an electrode's active area which leads to degradation, which is unfavourable to catalytic performance and device durability. 192 As a result, an effort such as nano-scaled/atomic engineered topcoat has been made to slow the ripening of high surface area catalysts and maintain high catalytic activity 193 which also may (i) alter the kinetics of dissociative adsorption of reactants, catalytic activity, ion incorporation kinetics, and/or atomic/ionic transport kinetics; (ii) may thermodynamically stabilize spatial chemistry, suppressing common electrode degradation mechanism; and (iii) hinder both Ostwald ripening and agglomeration of nanoparticles. 143 Oxides interfaces may improve the kinetics of catalysis, 194,195 which also applies to SOFC and SSOFC.…”

Summary Solid oxide fuel cells (SOFCs) are eco‐friendly and yet highly efficient power generation devices. However, SOFCs face some commercial issues with durability, reliability, sustainability, and fabrication costs. In recent years, a unique design idea of symmetrical cell configuration of SOFCs with similar anode and cathode materials, commonly known as SSOFC or SFC has piqued the interest among researchers. The present review article attempts to comprehensive reported research related to the current development of new and promising advances in SSOFCs. Until now, most research on SSOFCs has focused on identifying appropriate materials for the system configuration electrodes. The progress and advances in structures and electrode materials for SSOFCs are summarised here. The electrical and electrochemical behaviours of SSOFCs as well as the performance comparisons with the common conventional SOFCs, in the aspect of electrode materials, are analysed and discussed. This review article provides a comprehensive data source for further investigation and exploration related to this topic towards sustainable, low‐cost, and viable commercialisation of this green fuel cell, especially by utilising local minerals from one's country.
