Behavior of Magnetic SMAs
This chapter is devoted mainly to the modeling of thermo-magneto-mechanical behavior of magnetic shape-memory alloys (MSMAs). The modeling of MSMAs involves two communities: teams of specialists in magnetism – in particular, magnetostrictive materials – and teams grounded in physics and the strength of materials. The…
Use of the “CTM” to Model SMAs
On the basis of the crystallographic theory of martensite (CTM), a number of problems in monocrystals in shape-memory alloys (SMAs) can be viewed in a new light, and sometimes solved. Three cases are solved in this chapter: the process of reorientation of the martensite variants in a SMA monocrystal, the pseudo-elasti…
Design, synthesis and conformational investigations of novel conformationally restricted , -hybrid peptides and hydroxyethylamine isosteres
Understanding the folding pattern of peptides, whether natural or synthetic, is a key to the understanding of their three-dimensional structure and function. It is anticipated that use of specific non-covalent interactions to modulate the three-dimensional architecture and chemical properties of peptides would eventua…
Plasmon-enhanced upconversion in Yb3+/Er3+doped inY2O3
In this paper, we study the computational modeling of the localized surface plasmonic and scattering field effect arising from of gold nanorods. We also report the synthesis and optical characterization of core-spacer-shell nanocomposites composed of gold nanorods coated with SiO2 and finally coated with Y2O3:Er3+/Yb3…
二氯甲烷在CeyV1-yOx/HZSM-5上的催化燃烧性能
采用等体积浸渍法制备了不同铈钒摩尔比、不同活化温度（t）和不同负载量（m%）的一系列w%CeyV1-yOx/HZSM-5（t）催化剂,研究了其对低浓度二氯甲烷的催化燃烧活性及稳定性,考察了n（Ce）∶n（V）、负载量、活化温度对催化剂性能的影响。采用XRD,BET,NH3-TPD,XPS等手段对使用前后的催化剂进行了表征。实验结果表明,活化温度为400℃的15%Ce0.7V0.3Ox/HZSM-5（400）催化剂的活性最好,在反应温度300℃时二氯甲烷的转化率达99.6%,连续反应200 h时二氯甲烷转化率仍大于95%;使用后的15%Ce0.7V0.3Ox/HZSM-5（400）催化剂没有新的物相生成,具有较好稳定性。
S2O8^2-/ZrO2-SiO2固体超强酸的合成及其催化合成硬脂酸正丁酯
以五水硝酸锆和九水硅酸钠为锆源和硅源、过硫酸铵为浸渍液,采用共沉淀法制备了S2O82-/ZrO2-SiO2固体超强酸催化剂,并对催化剂进行了XRD,FTIR,SEM表征。以硬脂酸和正丁醇酯化合成硬脂酸正丁酯反应为探针,考察了催化剂制备条件和反应条件对酯化反应的影响。表征结果显示,SiO2的引入延迟了ZrO2的晶化和晶相的转化,当焙烧温度为550℃时,催化剂中四方晶型ZrO2结构和单斜晶型ZrO2结构同时存在,催化剂表面呈针状。在n（硝酸锆）∶n（硅酸钠）=2.0∶1.5、浸渍液过硫酸铵浓度0.5 mol/L、浸渍时间2 h、焙烧温度450℃、焙烧时间3 h的条件下制备的S2O82-/ZrO2-SiO2固体超强酸的催化活性较好。酯化…
OPINIONS AND DECISIONS
The chapter deals in turn with two exclusionary rules. The first, the opinion rule, governs the admissibility of inferences drawn by a person from observed or assumed facts. The second governs the admissibility of decisions, ie the outcome of fact-finding in another legal proceeding. Further constraints on testimony b…
Electric polarization in correlated insulators
We derive a formula for the electric polarization of interacting insulators, expressed in terms of the full Green's and vertex functions. We exemplify this method in the half-filled ionic Hubbard model treated within dynamical mean field theory (DMFT). The electric polarization of a correlated band insulator is determ…

Some General Points about SMAs
This introductory chapter of Shape-memory Alloys Handbook attempts to place shape-memory alloys in the context of physics and the mechanics of materials and to set out the key physical concepts of martensitic transformation and reorientation of martensite plates. There are two main families of Shape-memory Alloys (SMA…
Macroscopic Models with Internal Variables
This chapter highlights a few salient points of some of the macroscopic models relating to shape-memory alloys (SMAs), namely, RL model, anisothermal expansion model, internal variable model inspired by micromechanics, and elastohysteresis model, It presents the three-dimensional formulation where the strains and stre…
Engineering Boronsubphthalocyanine for Organic Electronic Applications
Boronsubphthalocyanines (BsubPcs) are a class of organic semiconducting materials which are relatively underdeveloped in their synthetic methods and organic semiconducting applications. A comprehensive investigation of these materials is explored in a rigorous and strategic manner progressing through each stage of the…
Fracture Mechanics of SMAs
Shape memory alloys (SMAs) are capable of mechanically-reversible phase transformations where large deformations can be obtained. These properties of pseudo-elasticity make SMAs particularly attractive in the biomedical domain. SMAs – magnetic or otherwise – may be considered to be brittle materials. This being the ca…

The World of Shape‐memory Alloys
Regarding Shape-memory Alloys (SMAs), Chang and Read were the first to detect a phase transformation in a Au-Cd alloy by metallographic observations and measurements of electrical resistance. “An overview of the basic metallurgy of commonly-used SMAs” has been written by Michel Morin. Only two categories of alloys are…
Orbital selective correlations between nesting/scattering/Lifshitz transition and the superconductivity in AFe1-xCoxAs (A=Li, Na)
The correlations between the superconductivity in iron pnictides and their electronic structures are elusive and controversial so far. Here through angle-resolved photoemission spectroscopy measurements, we show that such correlations are rather distinct in AFe$_{1-x}$Co$_x$As (A=Li, Na), but only after one realizes t…
