Graphene which is single or few atomic layer carbon atoms in a hexagonal network is emerging as a leader among the 2D nanoscale materials [1]. Structurally, graphene is free of defects, with all the carbon atoms linked together by strong and flexible bonds. This has made graphene to have unusual electronic, optical, m…
Axial magnetostriction in giant magnetostrictive materials with specific crystal orientation is highly anisotropic when changing magnetization direction. Based on a single-{111}-twin crystal growth model, this paper presents a domain rotation simulation of anisotropic magnetostrictions in 〈110〉 oriented crystals Tb0.3…
Nowadays, the attempts in the textile and clothing industry have moved towards more innovative and high quality products in order to differentiate themselves and be more competitive. The new demand for innovative textiles is increasingly oriented to match material innovation, new technologies and fashion. The new prod…
Bulk metallic glasses (BMGs) have received a great deal of attention due to scientific and technological interest ever since the first successful synthesis of an amorphous phase in the Au–Si system in 1960 (Klement et al., 1960). There has been a lot of interest to identify parameters to assess the glass forming abili…
This paper deals with the prediction of radiated emission of power electronics drive systems in the environmental conditions of aerospace applications. The aerospace norm and constraints define limits of radiated emissions for such systems. Thus, it is of importance to predict them in the design phase of the product d…
The photoinduced birefringence in glassy layers of the new photocrosslinking polymers containing benzaldehyde groups in the side chain is experimentally investigated. The kinetics of the birefringence recording is revealed to have an untypical shape compared to the known photosensitive materials of the same type. Unde…
Pure germanium nitride (Ge3N4) thin films were successfully formed on n-type Ge (111) substrate using an atmospheric-pressure (AP) nitrogen plasma. Their film structures and electrical properties were then examined in detail. Synchrotron radiation photoelectron spectroscopy clearly revealed that the Ge3N4 thin films f…
Magnetic core materials are considered critical components that influence an isolated DC/DC converter's dynamic response, efficiency and size. This paper illustrates the impact of core material choice in the design of a high frequency transformer for an isolated DC/DC converter for energy storage applications. The var…
This chapter introduces some facts about graphene, how it was discovered, how it has been realised by several approaches and how to get its identity. Its identity is seen either through cross-sectional TEM or through its unique signature in Raman spectra. We also briefly review bottom-up and top-down synthesis approac…
p-type nanocrystalline silicon thin films with a series of thicknesses were deposited on both glass and n-type (100) silicon wafer substrates through a low-frequency inductively coupled plasma. No H2 dilution was employed in the growth process. The structural and electric properties of nanocrystalline silicon films we…
Abstract A family of salts that was based on the [Ni(α‐tpdt) x ] n – anions (α‐tpdt = 2,3‐thiophenedithiolate) and the K + crown‐ether cations were prepared and were then structurally and magnetically characterised. In [K(18‐crown‐6)][Ni(α‐tpdt) 2 ], the anion has a square planar coordination geometry with ligand diso…
An experimental study on picosecond laser induced plasma spectroscopy of a zircaloy sample with low-pressure surrounding helium gas has been carried out to demonstrate its potential applicability to three-dimensional quantitative micro-analysis of deuterium impurities in zircaloy. This was achieved by adopting the opt…
The transient absorbance of poly(4-methyl-1-pentene) (PMP) irradiated with gamma rays at elevated temperatures has been investigated. The absorbance in the ultraviolet and visible range increases with gamma ray dose. A bathochromic shift in transmission spectra emerges significantly upon irradiation. A first-order gen…
Abstract The bioactive agents p ‐hydroxymethylbenzoate, 2,4‐dihydroxymethylbenzoate and methylsalicylate were reacted with polyoxyalkylene (D 230–2000 )–montmorillonite (MMT) intercalated nanocomposites. D 230–2000 –MMT were prepared by an ion exchange process of Na‐MMT andNH 3 + groups in polyoxyalkylene amine hydro…
Abstract A new method has been introduced to predict the power of important classes of energetic compounds including nitroaromatics, acyclic and cyclic nitramines, nitrate esters and nitroaliphatics. In this method, the predicted specific impulse and the corrected heat of detonation on the basis of H2O‐CO2 arbitrary d…
In this work, the partitioning of higher multipole polarizabilities, such as dipole-quadrupole, quadrupole-dipole, and quadrupole-quadrupole polarizabilities, into atomic contributions is studied. Partitioning of higher multipole polarizabilities is necessary in the study of accurate interaction energies where dispers…
4-Amino-4-deoxychorismate lyase (PabC) catalyzes the formation of 4-aminobenzoate, and release of pyruvate, during folate biosynthesis. This is an essential activity for the growth of gram-negative bacteria, including important pathogens such as Pseudomonas aeruginosa. A high-resolution (1.75 Å) crystal structure of P…
The large recovery force and non-linear deformation behaviour resulting from a change in the temperature in shape-memory alloys (SMAs) make them attractive materials for applications in smart materials and structures, as well as actuators. However, SMAs are limited in their application because they cannot support gene…
We investigate the rheological properties of an assembly of inelastic (but frictionless) particles close to the jamming density using numerical simulation, in which uniform steady states with a constant shear rate is realized. The system behaves as a power-law fluid and the relevant exponents are estimated; e.g., the…
1.1 Heat exchangers A heat exchanger is a component used to transfer heat from one medium to another. The media may be separated by a solid wall, so they never mix, or they may be in direct contact (Kakac and Liu 2002). Heat exchangers generally have no external heat nor work interactions and are typically used in the…
