“…Therefore, the development of composite MH alloys, which contain two or more hydrogen storage materials/intermetallic compounds/elements, can potentially combine the advantages of constituted alloys. Recent composite alloy studies include BCC related alloys modified by AB 2 (Section 2.6), AB 5 [227], LaNi 5 [213,214], ZrV 2 [220], A 2 B 7 -type [217], LaNi 3 [212], or other BCC [218], A 2 B 7 -type alloy modified by AB 5 [228], MgNi alloy modified by Ti(NiCo) [229], Mg 2 Ni alloys modified by TiNi, TiFe [230], (MgMn) 2 Ni [231], (MgAl) 2 Ni [232], Co, or Ti [233], and are summarized in Table 8.…”

In this review article, the fundamentals of electrochemical reactions involving metal hydrides are explained, followed by a report of recent progress in hydrogen storage alloys for electrochemical applications. The status of various alloy systems, including AB5, AB2, A2B7-type, Ti-Ni-based, Mg-Ni-based, BCC, and Zr-Ni-based metal hydride alloys, for their most important electrochemical application, the nickel metal hydride battery, is summarized. Other electrochemical applications, such as Ni-hydrogen, fuel cell, Li-ion battery, air-metal hydride, and hybrid battery systems, also have been mentioned.

“…As a result, these functional properties are closely linked to phase transformation temperatures. [4,5] The high sensitivity of transformation temperatures to alloy composition and processing history [6][7][8][9] has made efforts to create application-specific alloys problematic. Furthermore, traditional SMA fabrication technologies are performance limiting since monolithic components consist of only a single set of phase transformation characteristics.…”

Until now, shape memory alloys (SMAs) have been largely limited to “remembering” a single memory. In other words, monolithic components only possess a single set of functional properties. The current work describes how theorized change to local chemical composition induced through laser processing enables controlled augmentation of transformation temperatures. Proof of concept was demonstrated by locally embedding multiple shape memories into a monolithic NiTi component. This novel technique overcomes traditional fabrication challenges and promises to enhance SMA functionality and facilitate novel applications through producing a new class of smart materials; namely multiple memory materials (MMMs).

“…The ideal polymeric support should satisfy several features: good adhesion with the photocatalyst; a large specific surface area; high adsorption capability toward the reaction species; high chemical inertness; and good mechanical stability. Several methods have been developed to immobilize photocatalysts on polymeric supports, including electrospinning, sol–gel methods, atomic layer deposition, solvent‐casting process, hydrothermal methods, solvothermal methods, solution polymerization, ion exchange, and impregnation . Most of these methods can be performed at relatively low temperature to avoid damage to the polymeric supports.…”

Conjugated polymer/nanocrystal composites have attracted much attention for use in renewable energy applications because of their versatile and synergistic optical and electronic properties. Upon absorbing photons, charge separation occurs in the nanocrystals, generating electrons and holes for photocurrent flow or reduction/oxidation (redox) reactions under proper conditions. Incorporating these nanocrystals into conjugated polymers can complement the visible light absorption range of the polymers for photovoltaics applications or allow the polymers to sensitize or immobilize the nanocrystals for photocatalysis. Here, the current developments of conjugated polymer/nanocrystal nanocomposites for bulk heterojunction-type photovoltaics incorporating Cd- and Pb-based nanocrystals or quantum dots are reviewed. The effects of manipulating the organic ligands and the concentration of the nanocrystal precursor, critical factors that affect the shape and aggregation of the nanocrystals, are also discussed. In the conclusion, the mechanisms through which conjugated polymers can sensitize semiconductor nanocrystals (TiO2 , ZnO) to ensure efficient charge separation, as well as how they can support immobilized nanocrystals for use in photocatalysis, are addressed.
