This paper presents very small laboratory hybrid photovoltaic-hydrogen power system. The system was primarily assembled to verify the operability of the control algorithms and practical deployment of available commercial hydrogen technologies that are directly usable for storage of electricity produced from renewable…
This book presents both the fundamentals concepts and latest achievements of a field that is growing in importance since it represents a possible solution for global energy problems. It focuses on an atomic-level understanding of heterogeneous catalysis involved in important energy conversion processes. It presents a…
The National Council on Radiation Protection and Measurements (NCRP) established NCRP Scientific Committee 2-6 to develop a report on the current state of knowledge and guidance for radiation safety programs involved with nanotechnology. Nanotechnology is the understanding and control of matter at the nanoscale, at di…
ABSTRACT Clay/poly(glycidyl methacrylate) nanocomposites (clay/PGMA) were prepared by in situ radical photopolymerization using N,N‐dimethylaminopropyltrimethoxysilane(DMA)‐modified bentonite clay acting as hydrogen donor for benzophenone in solution. This initiating system permits to photopolymerize glycidyl methacry…
ABSTRACT Novel xanthate RAFT agents, RAFT1‐5, designed for the preparation of a range of novel N‐vinyl pyrrolidone‐based polymeric materials with linear and star architectures via RAFT polymerization are reported. Ethyl pyrrolidone moiety was included in the structures of the xanthates as a part of R (RAFT1‐3) or Z gr…
The Deinococcus radiodurans genome encodes homologues of divisome proteins including FtsZ and FtsA. FtsZ of this bacterium (Dr-FtsZ) has been recently characterized. In this paper, we study FtsA of D. radiodurans (Dr-FtsA) and its involvement in regulation of FtsZ function. Recombinant Dr-FtsA showed neither ATPase no…
The reaction of nitrous oxide with internal olefins is investigated in a flow reactor. When using a mixture of dodecene isomers, ketones are formed as the primary product with conversions up to 77% and yields up to 45%. The multiphase system is studied experimentally and computationally to gain understanding of the re…
After nearly 20 years of study, the origin of the spin-liquid state in ${\mathrm{Tb}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$ remains a challenge for experimentalists and theorists alike. To improve our understanding of the exotic magnetism in ${\mathrm{Tb}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$, we synthesize a chemica…
This paper presents the corrosion behaviour of welded low carbon steel at different welding voltages and filler materials. The welding process was conducted on butt joint specimens using the metal inert gas (MIG) technique at a welding voltage range of 19 to 21 V with 1 V interval, and the filler materials used were E…
The use of templates to assist and possess a control over the synthesis of nanomaterials has been an attractive option to achieve this goal. Here we have used sodium dodecyl sulfate (SDS) to act as a template for the low temperature synthesis of cobalt oxide (Co₃O₄) nanostructures. The use of SDS has led to tune the m…
Abstract Addition of organic matter ( OM ) to flooded soils stimulates reductive dissolution of Fe( III ) minerals, thereby mobilizing associated phosphate (P). Hence, OM management has the potential to overcome P deficiency. This study assessed if OM applications increases soil or mineral fertilizer P availability to…
We report spectroscopic measurements of highly charged samarium and erbium performed at the National Institute of Standards and Technology electron beam ion trap (EBIT). These measurements are in the extreme ultraviolet range, and span electron beam energies from 0.98 keV to 3.00 keV. We observed 71 lines from Kr-like…
A pectin lyase, named PLIII, was purified to homogeneity from the culture filtrate of Aspergillus giganteus grown in submerged culture containing orange peel waste as carbon source. PLIII was able to digest apple pectin and citrus pectins with different degrees of methyl esterification. Interestingly, the PLIII activi…
This study considers a common metallurgical problem associated with the phase transformation of steel during heating where austenite grain tends to grow in size with time and results in poor mechanical properties in the final stages. This investigation was performed using a Cellular Automata model for dual-phase steel…
This work focuses on the synthesis, functionalization, and application of gold and silver nanoparticles, magnetic nanoparticles Fe 3 O 4 , combination of 4-ATP-coated silver nanoparticles and Fe 3 O 4 nanoparticles. The synthesis methods such as chemical reduction, seeding, coprecipitation,and inverse microemulsion wi…
Shape memory alloys (SMAs) are a class of material that undergoes a reversible shape change after a plastic deformation. The recovery of the original shape is possible due to a structural transformation upon heating to a critical temperature. The shape memory effect is related to a martensitic-austenitic transformatio…
This study examined effect of a transcranial magnetic stimulation device with a commercial-frequency approach on the neuronal cell death caused ischemia. For a simple transcranial magnetic stimulation device, the experiment was conducted on an ischemia induced rat by transcranial magnetic stimulation of a commercial-f…
Three different size aluminum nanoparticles are introduced in order to study the effect of particle size on reactivity and combustion characteristics. Structure and morphology of these aluminum nanoparticles are characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results show that…
The application of voltammetric techniques to the study of chemical speciation and stability is addressed both theoretically and experimentally in this work. In such systems, electrode reactions are coupled to homogeneous chemical equilibria (complexations, protonations, ion associations, ...) that can be studied in a…
This paper presents the shape optimization of a permanent magnet synchronous motor to reduce the torque ripple and iron loss. Specifically, the harmonics of the electromotive force and cogging torque are decreased by adjusting the permanent magnet arrangement and non-uniform air gap length. In addition, an additional…
