ABSTRACT The aim of this work was to study the influence of two storage temperatures (0C and 5C) and three packaging films (low density polyethylene of 60 µm thickness, medium density polyethyle of 60 µm thickness and polyvinylchloride) on the quality of fresh‐cut Romaine lettuce stored under passive modified atmosphe…
Conducting polymer actuators that can undergo complex and coordinated motions are generally obtained by using complex microfabrication methods to pattern several conducting polymer components. Herein, we describe a facile approach for fabricating electromagnetic synergetic actuators based on polypyrrole/Fe 3 O 4 hybri…
SUMMARY: Novel tissue- and organ-engineering strategies are needed to address the growing need for replacement biological parts. Collective progress in stem cell technology, biomaterials, engineering, and molecular medicine has advanced the state of regenerative medicine, yet many hurdles to clinical translation remai…
The thermoelastic properties of SiC/epoxy nanocomposites are investigated through a molecular dynamics (MDs) simulation and micromechanics bridging method. One major finding from the MD simulation is that not only the elastic modulus but also the thermal expansion coefficient of the nanocomposites exhibits particle-si…
A novel 4-[(8-hydroxyquinolin-5-yl)methyl]aminobenzenesulfonamide (HQMABS) was synthesized by optimized reaction of 4-aminobenzenesulfonamide with 5-chloromethyl-8-hydroxyquinoline hydrochloride (CMHQ). Various oxinates of HQMABS were also prepared using Mn(II), Fe(II), Co(II), Ni(II), Cu(II), and Zn(II) metal salts.…
Hydrogels are playing an increasing role in regenerative medicine owing to their growing functional sophistication. This is being underpinned by advances in hydrogel synthesis, particularly through molecular and genetic engineering, which provide greater control of hydrogel structure and hence the emergence of hydroge…
Smart nanostructures are sensitive to various environmental or biological parameters. They offer great potential for numerous biomedical applications such as monitoring, diagnoses, repair and treatment of human biological systems. The present work introduces smart nanostructures for biomedical applications. In additio…
This paper shows a new signature for detection of rotor bar faults in induction motors trough external magnetic field analysis. The proposed method is based on the variations of the axial flux density in the presence of rotor faults, particularly regarding the low frequency part of the frequency spectrum. The analysis…
AbstractThe development of biomaterials for the repair or replacement of hard tissue is a challenging and a promising area of research. Engineering cell and tissue behaviour at biomaterial surfaces at the nanoscale level can be accomplished by chemically modifying surfaces with biologically active macromolecules or ph…
In bacteria, a subset of transcription termination events requires the participation of the transcription termination factor Rho. Rho is a homo-hexameric, ring-shaped, motor protein that uses the energy derived from its RNA-dependent ATPase activity to directionally unwind RNA and RNA-DNA helices and to dissociate tra…
Abstract The microstructure evolution in heat-treatable Al-alloys is characterized by a complex sequence of precipitation processes. These can be either endothermic or exothermic in nature and they can be investigated by thermal analysis. The individual peaks identified in a differential scanning calorimetry (DSC) ana…
Polarization properties of a magneto-photonic layered structure are studied at frequencies close to the frequency of ferromagnetic resonance. The investigations are carried out taking into account a large value of dissipative losses in biased ferrite layers in this frequency band. The method is based on analysis of so…
A novel three-phase double sided flux switching linear motor topology with a stator-to-mover teeth ratio of 19/24 is presented. Finite element analysis of the electromagnetical performance of the initial design is conducted and shows that the topology suffers from an unbalanced EMF in terms of amplitude and phase shif…
The structural and optical properties of aluminum nitride (AlN) films deposited on glass and silicon substrates by single ion beam sputtering technique have been investigated. The X-ray diffraction and Fourier transform infrared spectroscopy (FTIR) study revealed the formation of the amorphous phase of AlN. The optica…
This paper investigates the impact of supply harmonic voltages on DFIG stator current and power spectra. The influence of individual higher order supply harmonics on DFIG stator current and on total instantaneous power spectral content is investigated using a time-stepped circuit model. The observed effects are identi…
The effect of focus splitting after propagation of focused ultrasound through a rib cage is investigated theoretically. It is shown that the mechanism of this effect is caused by the interference of waves from two or more spatially separated sources, such as intercostal spaces. Analytical estimates of the parameters o…
Some fifteen years ago a paper reporting a combinatorial approach to materials discoveries revolutionized materials research and other disciplines such as chemistry and pharmacology [1]. Here we report on how a combinatorial approach combined with advanced nanofabrication helps to discover photonic metamaterials optim…
For high-speed machines applications, eddy-current losses in the interior permanent magnet of synchronous machine (IPMSM) form a portion of the total losses which can be significant. Indeed, the magnets are exposed to the harmonic fields which rotate with respect to the rotor. The induced losses in the magnets provoke…
CrAlN and TiAlN coatings were deposited on stainless steel substrates by a lateral rotating cathode arc technique. The composition and structure of the as-deposited coatings were analyzed by energy dispersive analysis of X-rays (EDX) and X-ray diffraction (XRD). Thermal conductivity of these coatings is measured using…
The electrochemical processing of spent metallic nuclear fuel has been demonstrated by and is currently in operation at the Idaho National Laboratory (INL). At the heart of this process is the Mark-IV electrorefiner (ER). This process involves the anodic dissolution of spent nuclear fuel into a molten salt electrolyte…
