shape morphing structures via intercalation compounds

Multifunctional Material Systems: A state

2016/9/1Due to their shape morphing ability, SMPs are also being studied for use in deployable structures . The main advantage of using SMPs for space applications is that it could greatly reduce the volume, weight, and cost of the structure compared with traditional self-deploying techniques.

Multifunctional Electrochemical Systems

Initial work with graphite intercalation compounds generated actuators with energy densities on the order of 1 MJ/m3 that rival those of NiTi shape memory alloys. We then extended this concept to electroplating of metals as an actuation mechanism.

2 intercalation compounds occupy the same positions in the van der Waals gap, which are octa-hedrally coordinated by chalcogen. Therefore, a competition for the occupation of these positions can be expected. The crystal structure of the TiSe 2 compound is

Studies of intercalation compounds include the effect of cation doping and ordering on the mechanisms by which these materials react. In-situ NMR Studies of Battery and Supercapacitor Function We have developed NMR methodology to monitor structural changes that occur during the operation of a battery/supercapacitor.

Mechanical properties of shape memory polymer

Shape memory polymers are temperature-controlled variable stiffness materials, which have potential for use as morphing skins. Shape memory polymer skins undergo large strain in their flexible, rubbery state and resist aerodynamic loads in their stiff, glassy state.

Correlations of crystal structures of DNA oligonucleotides

Rh(phen)2phi3+ (phen = 1,10-phenanthroline; phi = 9,10-phenanthrenequinone diimine) avidly binds to DNA via intercalation from the major groove and upon photoactivation produces strand scission with single base 5' asymmetry. Enantiomers of Rh(phen)2phi3

Shape morphing structures via intercalation compounds

This technology can be used in any moderate bandwidth, high-force, high-strain application, including shape-morphing helicopter blades, boat hulls, satellites, and any other structure that benefits from shape change. An analysis is performed on the state of the

Electrochemical tuning of vertically aligned MoS2

Significance The electronic structures of two-dimensional materials can be tuned for a variety of applications by guest species intercalation into the van der Waals gaps. Using Li electrochemical intercalated MoS 2 as an example here, we correlate the continuously tuned electronic structure of lithiated MoS 2 with the corresponding enhanced hydrogen evolution reaction activity, and thus

Shape

2020/4/7Structures that can change their shape are advantageous in a wide variety of applications such as aerospace, renewables, and robotics. The problem with current shape-changing technologies is that they are either heavy, lack mechanical stiffness, or are hard to control. This paper demonstrates a shape-changing carbon fiber composite material, which is lightweight, has a stiffness higher than

Investigations on DNA intercalation and surface binding

Photocleavage of DNA by the cyanine dyes YO, YOYO and TOTO has been shown to mainly occur via single-strand cleavages ( 30), which is rather unlikely to lead to the observed diffuse bands. On the other hand, photocleavage mechanisms have been reported to be dependent on the dbpr, and single-strand breaks may accumulate to eventually produce double-strand cleavages ( 30 ) that may account for

Change in the shape and density of dendritic spines

Dendritic spines are morphing structures believed to provide a cellular substrate for synaptic plasticity. It has been suggested that the actin cytoskeleton is the target of molecular mechanisms regulating spine morphology. Here we hypothesized that acidic calponin

These compounds are accessible via a salt metathesis reaction of LB⋅E′H 2 Cl and KAsH 2 and a H 2 elimination reaction between LB⋅E′H 3 and AsH 3, respectively. In addition, the unprecedented branched compounds IDipp⋅E′H(EH 2 ) 2 (E′=Al, Ga; E=As, P could be obtained.

Core level shifts of intercalated graphene

2016/11/4Upon deposition or intercalation, the initial rather narrow and almost symmetric C1s line shape is asymmetrically broadened and develops a shoulder towards higher BEs. Bennich et al [ 21 ] attributed the asymmetric broadening of the C1s peak to electron–hole pair formation fostered by an increased phase space for such excitations with doping level.

Applied Sciences

The term morphing aircraft describes a broad range of air vehicles that can adapt their shape to planned and unplanned multipoint mission requirements. Adaptation appears in some sense more understandable than morphing and suggests the capability to change the relevant states of an air vehicle such as its shape.

Lin et al. describe an intercalation-based exfoliation method for the scalable production of high-purity 2D semiconductor monolayers in the liquid phase. The key to the high-yield exfoliation is the complete intercalation of layered crystal through a unique "intercalation and separation" chemistry. Re-assembling these monolayers through the facile solution-based techniques results in a

Autonomous vehicles are energy poor and should be designed to minimise the power required to propel them throughout their mission. The University of Southampton's School of Engineering Sciences is actively involved in the development of improved designs for aerial and maritime autonomous vehicles. The ability to adapt or 'morph' their shape in-flight offers an opportunity to extend
