Flax fibers may be blended with cotton to provide an aesthetic property, improve performance and tailor fabric properties. The quality and cost of the woven fabric blends are affected by the amount of linen in the blend. Microscopic and chemical analyses are currently used to determine linen content in fabrics. This s…
Anisotropic Nd–Fe–B thin films with c-axis texture are fabricated by dc magnetron sputtering on heated Si substrate. The influence of Ti or Mo buffer layer thickness and substrate temperature on the surface morphology, the domain structure and the magnetic properties are investigated and compared for the Nd–Fe–B films…
A tool for tritium inventory evaluation within each sub-system of the Fuel Cycle of ITER is vital, with respect to both the process of licensing ITER and also for operation. It is very likely that measurements of total tritium inventories may not be possible for all sub-systems, however tritium accounting may be achie…
Recovery of tritium released into a working area in a nuclear fusion plant is a key issue of safety. The catalytic oxidation of isotopic hydrogen including tritium is a conventional method for removing tritium from the air of the room. If a tritium release accident occurs in the fusion plant, large volumes of air shou…
Soft tissue engineering strategies targeting restoration of volume loss have inherent critical challenges as they relate to the problem of restoration of defects with a high volume to surface ratio. We outline the problems associated with the limitations of translational applications regarding soft tissue engineering…
A thermodynamic corium database using ionic two-sublattice model for liquid was developed and stratification of molten corium, supposed to occur in in-vessel retention accident management, was analyzed. The database consists of U—Zr—Fe—O—C—B–(FP oxides) system. Fundamentally, data were obtained from existing assessed…
Broadband dielectric spectroscopy was employed to study the behavior of propylene glycol trimer (Tri-PPG). Measurements for different conditions of temperature and pressure allowed the effect hydrogen bonds on the complicated relaxation behavior to be clarified. We find that both the $\ensuremath{\alpha}$ and $\ensure…
The biosynthesis of one riboflavin molecule requires one molecule of GTP and two molecules of ribulose 5-phosphate as substrates. GTP is hydrolytically opened, converted into 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidinedione by a sequence of deamination, side chain reduction and dephosphorylation. Condensation with 3,…
In this paper, results of ab initio pseudopotential density-functional calculations of indium adsorption on graphitelike surfaces are presented. The adsorption energy was calculated as a function of In coverage, and it is shown that, for low surface densities, In becomes positively charged by donating about one electr…
The magnetic susceptibility and Curie temperatures T c have been investigated for a series of synthetic samples with solid-solution compositions ranging from pure magnetite (Fe 3 O 4 ) to hercynite (FeAl 2 O 4 ). The determined T c can be fitted by a straight line, which also fits the theoretical values for these end-…
The optical, electronic, and electrochemical properties of thin films of the electroactive polymer, poly(3-butylthiophene) (P3BT), were studied in a lithium hexafluorophosphate electrolyte. Upon extraction of n electrons per polymer formula unit, anions are taken up to balance the charge, forming a polymer cation salt…
The electrochemical behaviour as well as the surface morphology characteristics of electrodeposited Zn and Zn-Co (≈3 wt-%) alloy coatings on low carbon steel samples, with and without included nanoparticles of organic co-polymers in their structure, are discussed. Their corrosion resistance and protective properties w…
Elliptically polarized light-scattering measurements were performed to investigate the dispersion behavior of multiwalled carbon nanotubes (MWNT). Xylene- and pyridine-derived MWNT powders were dispersed in water and ethanol in separate optic cells and allowed to sit undisturbed over a two-week time period after probe…
Photo-oxidation of arsenic trisulfide is the process whereby the surface of As2S3 glass is chemically altered and degraded due to exposure to light in the presence of water vapor. For as-deposited, thermally evaporated, As2S3 thin films the degradation process and the subsequent products formed vary as a function of i…
Si 1 − x Mn x alloy films of 50 nm thickness with 0.005⩽x⩽0.035 were grown by low-temperature molecular-beam epitaxy onto Si(100) substrates held at temperatures T in the range of 150°C⩽T⩽350°C. All films exhibit surface roughness with ∼20-nm-lateral and ∼1-nm-vertical length scales. This roughness is random for films…
This paper presents a method for modeling symmetric minor loops in hysteretic magnetic media. The method employs symmetric minor loops combined with certain segments of the initial magnetization curve to identify the classical Preisach model. The proposed method is simple and effective. It exploits the symmetric posit…
A numerical procedure for the prediction of fogging and defogging phenomena is presented. The simulation involves the solution of an air flow field along a cold solid surface, the evaluation of the unsteady conduction through the solid itself, and a model for the heat and mass transfer within the thin water layer on t…
The TMAP code has been upgraded to version 7, which includes radioactive decay along with many features implemented in prior versions. Pursuant to acceptance and release for distribution, the code was exercised in a variety of problem types to demonstrate that it provides results in agreement with theoretical results…
Based on magnetic structure and TEM studies of bornite we propose a new 2α Fe/Cu ordered superstructure model with symmetry F4̅3m and formula Cu 8 Fe 4 S8. First principles calculations (LAPW implemented in WIEN97 code) of two Fe/Cu ordering schemes indicate that, at the ground state, the Fe atoms should fill the tetr…
The American National Standards Institute/NSF Standard 61, Section 8, is intended to protect the public from inline brass plumbing products that might leach excessive levels of lead to potable water. Experiments were conducted to examine the practical rigor of this test. Contrary to expectations, the test was not high…
