The effect of application of cellulose-based edible coating, hydroxypropyl methylcellulose (HPMC) to mature-green tomatoes on the firmness and color was investigated. Tomatoes were stored at 20 degrees C for up to 18 days. Firmness decreased as storage time increased in all treatments. However, application of HPMC edi…
The degradations of phenol in air-equilibrated aqueous media were investigated using coupled sonochemistry and Fenton's reagent for a variety of operating conditions. The decomposition yields of phenol (100-500 microM) were substantially enhanced due to the addition of Fenton's reagent (FeSO4 into the solutions irradi…
The numerical simulation of the absorption and scattering cross sections of vanadium dioxide nanoparticles with silver and gold shells are presented. The cross sections are evaluated for the spectral intervals 1–1.2, 1.3–1.7, and 9–12 µm both before and after the semiconductor-metal phase transition in VO 2 . It is de…
The water absorption behaviour and the effects of ageing on the mechanical properties of short sisal fibre reinforced polystyrene composites have been studied with special reference to fibre loading and fibre-matrix interface modification. The composites were subjected to different ageing conditions viz., immersion in…
Based on the results of fracture in polymethyl methacrylate and a spheroplastic using a magnetic-pulse setup, the specific work of the formation of a new surface is estimated, which is similar to Griffith’s surface energy for quasi-static tests. The value obtained is greater than the corresponding value determined fro…
A new scheme of modified embedded atom method (MEAM) is proposed in this paper. The analytic form of the embedding function is modified. All the parameters of MEAM have been reset by relating them with bulk properties and some non-bulk properties, for example, the bond length of a dimer and the change of surface inter…
AIMS: To analyse the possible effect of poly-beta-hydroxyalkanoate (PHA) consumption on 2,4,6-trichlorophenol (2,4,6-TCP) degradation during starvation by Sphingopyxis chilensis S37 strain, which stores PHAs and degrades 2,4,6-TCP. METHODS AND RESULTS: The strain was inoculated in saline solution supplemented with 2,4…
This study describes for the first time results of a (19)F-MRS study on humans exposed to the fluorinated non-steroidal anti-inflammatory drug niflumic acid. The accumulation and elimination of this commercially available selective prostaglandin synthase inhibitor is studied after an oral bolus in the human liver, in…
Textile materials and products are increasingly used for technical applications. In some areas, textiles with 3D shapes are essential. This paper describes efforts to engineer, design, manufacture, and assess 3D domed woven fabrics. The research involves an easily mountable add-on device for looms that enables the pro…
Abstract Rheometric and mechanical properties, hysteresis and swelling behavior of the Styrene-Butadiene Rubber vulcanizates (SBR) filled with unmodified and novel electron beam modified surface treated dual phase fillers were investigated. Scorch time increases for these modified filler loaded vulcanizates due to int…
A previous study, leading to the redefinition of Seminavis ventricosa (Gregory) Garcia-Baptista and some related taxa, made it clear that a considerable number of species exist within Seminavis D.G. Mann. Many species are still classified under Amphora Ehrenberg, although they clearly share common morphological featur…
Abstract We have developed a polymer dispersed cholesteric liquid crystal which exhibits two stable states at zero field: reflecting planar texture and non‐reflective focal conic texture. Both states have thresholds under driving voltage pulses. The material can be used to make multiplexed displays on passive matrix.…
Nedium cape-codii Siver & Hamilton sp. nov. is described from a small glacial kettle lake situated on the Cape Cod peninsula, Massachusetts, U.S.A. Nedium cape-codii is a large diatom with slightly bowed margins, a single longitudinal canal along each valve margin and sagittate apices. Each areola is covered externall…
The alignment mechanism of a polyimide surface bombarded with an atomic beam is investigated. Atomic beam treatment of polyimide films allows a liquid crystal (LC) to align parallel to the beam direction. This alignment mechanism is demonstrated by the selective destruction of double bonds in polyimide. The optical re…
Pulsed laser deposition has been used to grow highly oriented SrxBa1−xNb2O6 (SBN:x) on (001)MgO and miscut MgO (2° off 001 toward 100) in the presence of a pulsed O2 jet. The target stoichiometry was SBN:52±1.5%, but films grown at 700 °C were cation deficient and had a final composition of SBN:61±1.5%. Visually, the…
Depletion interactions between colloidal particles dispersed in a fluid medium are effective interactions induced by the presence of other types of colloid. They are not instantaneous but built up in time. We show by means of Brownian dynamics simulations that the static (mean-field) depletion force between two guest…
We describe a modular detector system suitable to intercept the diffracted x-ray radiation (Debye–Scherrer rings) in a transmission geometry setup at monochromatic tunable synchrotron radiation beamlines. The detector consists of several independent channels composed of a motorized front slit and a rear detector slit…
An elaborate finite element formulation was developed for the triaxial woven fabric (TWF) composites and this is presented in a parallel publication [Zhao, Q. and Hoa, S.V. Triaxial Woven Fabric (TWF) Composites With Open Holes (Part I): Finite Element Models For Analysis, Accepted, Journal of Composite Materials, thi…
An ethynylene-bridged zinc porphyrin dimer bearing metal-coordinating groups, such as bis[{5-(4-pyridyl)-15-(3,5-didodecyloxyphenyl)porphyrinato}zinc] Z2, self-assembles in CHCl 3 to form a rectangular-shaped supramolecular nano box, in which all the Z2 units preferentially adopt a planar conformation with a syn-paral…
In recent years, single crystal Cu-Al-Ni alloys with shape memory behavior (SMB) became generally commercialized. They achieved the level of extended application, including upper limb human prosthesis with anthropomorphic characteristics. An actuator based in single crystal Cu-Al-Ni alloy was tested as a prototype for…
