“…Using this method, they were able to obtain full shape recovery of their polymers upon irradiation with solar light at lower thresholds than previously reported with intensities between 130 and 160 mW cm –2 while no recovery was observed for the same polymer without the nanoparticles added. [ 166 ] Leng et al made use of carbon nanoparticles in combination with a shape‐memory polymer to show the possibility of a precisely localized trigger allowing for precise control over the location of the shape recovery.

One of the most promising fields for shape-memory polymers is the biomedical field. Shape-memory polymers that can be triggered by various (physiological) conditions such as temperature and moisture have been reported, as well as remotely triggerable shape-memory polymers that make use of electromagnetic fields, ultrasound, etc. These polymers have shown great promise in in vitro studies as well as in early in vivo studies. Their biocompatibility, and in some cases biodegradability, renders them excellent candidates for minimal invasive surgery and for the design of triggerable biomedical devices. The current review provides a nonexhaustive overview of recent developments realized throughout the last decade in the field of shapememory polymers serving specific biomedical applications while considering relevant triggers and biocompatible chemistries.

“…Making use of these superior properties, Li et al developed a TiN-SiO 2 -TiN broad band solar absorber, which can absorb 95% of light over the range of 400-800 nm with 240 nm thick device [35]. Similarly, Ishii et al fabricated TiN-ZnO-TiN structure, which showed superior performance in comparison to gold in visible region [36]. Both these devices were chemically robust, stable at high temperature and can be used in several emerging technologies such as solar-thermophotovoltaics (STPV), heat-assisted magnetic recording (HAMR).…”

Epitaxial nitride thin films and heterostructures are one of the most celebrated class of materials not only due to their utility in fundamental materials science and device physics studies, but also for their numerous industrial applications from hard coating technology to solid-state lighting. Transition metal nitrides such as TiN and others have been utilized for decades in hard coating and tribology applications. The last two decades have also seen the emergence and dominance of GaN for solid-state lighting and power electronic applications. Though TiN, and other wurtzite III-nitride semiconductor such as GaN remain the most important nitride coating materials for a range of applications, several other rocksalt nitride thin film and superlattice heterostructures such as ScN, CrN, and TiN/(Al,Sc)N metal/semiconductor superlattices have attracted significant interests in recent years for applications in thermoelectricity, plasmonics, solar energy conversion, and in high temperature electronic, optoelectronic, and plasmonic devices. In this chapter, we present an up-to-date summary of rocksalt nitride thin film and heterostructure coating materials for their applications in energy transport and conversion research fields. The suitability and usefulness of such nitride coating materials in the most recent scientific and engineering advances related to the energy transport and conversion research fields are highlighted.

“…Shape memory polymers (SMPs) are a class of stimuli‐responsive materials, which have the ability of changing their shapes from a temporary state to their original or permanent shapes upon the application of external stimulus, such as light, solvent, heat, pH, electric field, or magnetic field . The numerous potential applications in information carriers, biomedical field, actuators, assembly/disassembly, and aerospace, have stimulated intense interest in this area over the last decade.…”

In the last several years, multiple‐shape memory liquid crystalline networks (LCNs) have received more and more attention due to the basic theoretical research on them and their wide potential applications. In this article, a novel main‐chain/side‐chain liquid crystalline monomer and its corresponding polymer networks based on the thiol‐ene click reaction are reported. Properties of the synthesized liquid crystalline monomer are well studied with nuclear magnetic resonance (NMR), Fourier transform infrared (FTIR) spectra, differential scanning calorimetry (DSC), and polarized optical microscopy (POM). The as‐prepared free‐standing LCN films are investigated well by FTIR, DSC, POM, and X‐ray diffraction (XRD), which show them having good liquid crystalline properties. Tensile test and dynamical mechanical analysis (DMA) results indicate the LCN films have excellent thermal mechanical properties. By adjusting the crosslinking densities, LCN films exhibit two thermal transition temperatures (Tg and TNI) that can be utilized to trigger the triple‐shape memory behaviors. The cyclic thermal mechanical analysis conducted by DMA reveals that LCN films exhibit good triple‐shape memory properties with high‐shape fixity ratio (Rf (S1→S2) is 99.2% and Rf (S2→S3) is 99.3%) and shape recovery ratio (Rr (S3→S2) is 92.4% and Rr (S2→S1) is 98.5%).
