This concluding chapter draws upon the discussion on different aspects of nanotechnologies presented in the preceding chapters. It looks at the relevant materials, products and applications objectively, and analyses the likely benefits and potential risks to the consumer. It concludes that application of nanotechnolog…
Mechanical failure of component parts as well as in build up structures can be prevented if proper quality control is carried out at point of component’s manufacture. Engineers are known to analyze samples from which accurate predictions are made about the properties of the materials that are produced for the purpose…
Abstract Single-hole and spherical carbonaceous microcapsules were fabricated via controlling the carbonization, hydrolysis, and bulging force of yeast cells during hydrothermal processing. Moreover, magnetic nanoparticles could be easily coated onto these microstructures, endowing the obtained structures with multifu…
Physical-chemical surface modifications represent a formidable tool to drive a suitable cell behavior on materials intended to be used in the biomedical field. Plasma processes are among the more powerful methods utilized to modify the surface of materials without altering their bulk intrinsic properties. In particula…
Abstract Here we report a novel approach for preparation of ZnSe nanodot arrays by physical vapor deposition on porous aluminum oxide templates possessing ordered system of channels. The structure of nanodot arrays was investigated by scanning electron microscopy and EXAFS‐spectroscopy. The geometry of nanodots and lo…
We study a binary mixture of short and long parallel hard rods in the smectic A phase to understand the role of length ratio (weight ratio) in the formation of three different types of ordering which were observed in binary mixtures of helical polysilanes. Using Onsager’s second virial theory of parallel hard rods, an…
In this study, finite element method and X-ray diffraction measurement were used to determine the thermal stress distribution of functionally graded WC–Co composites. The calculated results show that high stress concentration occurs in the cobalt gradient zone, tensile stress pile-up occurs in the cobalt rich zone and…
The effective differential cross section (DCS) for elastic scattering of electrons by atoms is proposed that reproduces known energy dependences for the first and second transport cross sections but provides a total elastic cross section that is significantly small compared with the known energy dependences. The numbe…
We have synthesized various molecular cruciforms consisting of two different crossing n-systems and comprising crosswise arranged thiol- and pyridine-anchor groups. With these model compounds we strive towards the investigation of a new switching concept based on the potential dependent coordination of pyridines to go…
The convergence of nanotechnologies with the food and food processing sector will further revolutionise the agri-food sector. Yet despite the growing concern of the potential risks posed by some engineered nanoparticles, and the adequacy of existing legislative frameworks to protect human health and safety, a number o…
Abstract Two novel silver complexes [Ag2(Hsal)2]n (1) and [Ag2(oda)]n (2) (H2sal = salicylic acid, H2oda = oxydiacetatic acid) were synthesized hydrothermally by reaction of AgNO3 with H2sal or H2oda and characterized by IR spectroscopy, elemental analysis, and single‐crystal X‐ray diffraction. Compound 1 shows a 2D m…
The multi-degrees of freedom surface permanent-magnet motor (Multi-D.O.F. SPM) has several degrees of freedom operations that are defined as the "roll", "yaw", and "pitch". Normally, the torque that is generated to rotate a rotor includes ripples. The analysis of the torque ripples is important for improving motor per…
In this paper, the electromagnetic (EM) wave absorbers using TiO2 as a dielectric material with chlorinated polyethylene (CPE) were investigated in W-band radio frequencies. We compared the relative permittivity with reflectionless curve and the absorption properties of samples containing 40 wt.%, 50 wt.%, 60 wt.%, 70…
The aim of this work is to investigate the finite deformation behavior of polymeric materials under monotonic loading—unloading. The strain rate sensitivity behaviors of polymeric materials were modeled using viscoplasticity theory based on an overstress (VBO) model. The modeling capability of the VBO model was improv…
In this paper, a new algorithm has been introduced to regulate the DC capacitor voltage in single phase shunt active power filters to supply converter losses over the grid. In the system, the DC busbar voltage cannot be kept stable due to converter losses. The variation in DC busbar voltage decreases the power supplie…
Abstract Sr6[CoN2]2[CN2] was prepared from Sr2N, carbon, cobalt, and NaN3 as nitrogen source. The crystal structure (I4/mmm (no. 139), a = 383.55(10) pm, c = 1237.8(4) pm) represents a Na2[HgO2] type arrangement with both linear [CoIN2]5– and smaller [CN2]2– ions mutually occupying the [HgO2] position.
Acoustic single bubbles in aqueous solutions of sodium dodecyl sulfate (SDS) have been studied. In dilute SDS solutions, the trapped bubbles are found to be stabilized and sustainable up to higher driving acoustic amplitude. Stroboscopic images of the bubble are consistent with theory, indicating dancing motion and in…
Background and Purpose: In combination with metabolic heat, the heat generated by human activities and worn garment produce 6 basic factors (sometimes called 6 basic parameters because they are in space and time, but fixed representative values are frequently used in analyses) which define thermal body environments.Th…
Abstract Bayesian design of experiments is a powerful method which offers several distinct benefits over standard experimental designs. The basics of the method are briefly described, followed by four case studies giving a step‐by‐step illustration of its application to both bimolecular and unimolecular NMRP. Firstly,…
Abstract This work presents a study of carbon tetrabromide (CBr4) as precursor to deposit 3C‐SiC on (001) and (111) Si by VPE technique at temperatures ranging between 1000 °C and 1250 °C. TEM, AFM and SEM results indicate that the epitaxy proceeds as a 3D growth of uncoalesced islands at low temperature, whereas a co…
