The spatial structure and dynamics of hen egg white lysozyme have been investigated by small-angle and inelastic neutron scattering. Analysis of the results was carried using the fractal approach, which allowed determination of the fractal and fracton dimensions of lysozyme, i.e., consideration of the protein structur…
The reaction between HOCO and NO(2) has been examined using the quadratic configuration interaction method to locate the transition states and intermediates involved in the reaction. Analysis of the potential energy surface suggest that two possible intermediates are involved: HOC(O)ONO and HOC(O)NO(2). These new spec…
The electron conductance through a single-walled carbon nanotube is determined analytically by using the fact that a potential well transverse to the tube can be considered. In fact, the conduction electrons are conceived as standing waves in the above-mentioned potential well.

The structure of the adhesive silk of the Uloborus walckenaerius spider has remained unsolved due to its unremarkable material properties. In this work, we investigate the microstructure of Uloborus spider cribellar silk using probe microscopy techniques. Nanofibrils in a section of cribellar silk from the pyriform gl…
In the crystal structure of the title compound, [Co(NCO)(2)(C(4)H(4)N(2))(2)](n), the Co(II) cation is coordinated by four N-bonded pyrazine ligands and two N-bonded cyanate anions in a slightly distorted octa-hedral geometry. The crystal structure consists of μ-N:N' pyrazine-bridged cobalt cyanate chains; these are f…
The effect of modified atmosphere (MA) packaging using CO2 (50%) combined with different balancing gases (N2 and O2, 50%) was investigated and compared to packaging in air. In addition, the suitability of phosphate brining and steaming as a pretreatment of desalted cod to increase product quality was investigated. Hea…
Iron oxide nanoparticles were synthesized via reverse micelle methods. The initial iron concentration was varied, while maintaining all other parameters constant, in order to investigate the effect of the iron concentration on the resultant iron oxide nanoparticle size. Increasing the iron concentration from 0.125M to…
The Chapter is devoted to reviewing the main features of aging in non disordered systems relaxing via domain growth, after an istantaneous temperature quench. Using the autocorrelation and autoresponse functions to gauge the deviation from equilibrium, an hierarchy of processes is obtained by changing the temperature…
The structural stability and vibrational properties of different sizes and charge states of the hydrogen saturated spherical and cagelike C nanoparticles were investigated by means of ab initio density-functional theory. The cagelike nanoparticles remain stable and stiff under structural relaxation, whereas specific s…
Ceramics and other brittle materials suffer multiple surface cracking when subjected to quenching. These surface cracks greatly influence the thermal fracture behavior of brittle materials. This paper considers an array of parallel edge cracks with alternating lengths in an elastic plate subjected to a thermal shock.…
The external insulation of electrical equipments is affected by the atmospheric parameters in high-altitude regions. However, there is a lack of studies conducted at the high-altitude sites of 3000 m and above worldwide so far, in contrast to many fruitful ones carried out in the artificial climate chamber. The author…
The principal bottleneck in protein structure prediction is the refinement of models from lower accuracies to the resolution observed by experiment. We developed a novel constraints-based refinement method that identifies a high number of accurate input constraints from initial models and rebuilds them using restraine…
Films that are nanostructured in all three dimensions can be fabricated by the templated growth of ionic self-assembled multilayers (ISAMs) on solids that have been patterned by nanografting. Nanografting was used to controllably pattern -COOH surface groups on a background of -OH groups. Atomic force microscopy (AFM)…
The thermal transformation of Co(H 2 PO 4 ) 2 ·2H 2 O was studied under a dry air atmosphere using TG−DTG−DTA. The TG−DTG−DTA curves show that the transformation occurs in three steps, which are dehydration processes. Co(H 2 PO 4 ) 2 ·2H 2 O and its thermal transformation product were characterized by scanning electro…
Extensive understanding and management of the thermal-mechanical characteristics of novel packaging designs during the bonding process are indispensable to the realization of the technologies. Thus, this paper attempts to explore the bonding process-induced thermal-mechanical behaviors of an advanced flip chip (FC) el…
Abstract The curing characteristics and mechanical properties of blends constituted by acrylic rubber (ACM) and nitrile rubber (NBR) were investigated. The curing process was performed by a combination of curing systems specific for each rubber component. The curing system for the ACM phase consisted of hexamethylene…
The effects produced by swift heavy ions in the martensitic (18R) and austenitic phase (β) of Cu based shape memory alloys were characterized. Single crystal samples with a surface normal close to [210](18R) and [001](β) were irradiated with 200 MeV of Kr(15+), 230 MeV of Xe(15+), 350 and 600 MeV of Au(26+) and Au(29+…
Material selective sensitivity of a magneto-optical polar Kerr effect to magnetic contributions from different inclusions in self-organized magnetic nanostructures is presented. The method is supported by modeling of the magneto-optic response based on the effective medium approximation and by hysteresis loop measurem…
The increasing interest in combustion of solid recovered fuels (SRF), whose physical properties may significantly differ from those of conventional solid fuels, draws attention to the handling of these materials. In this article a simple method for evaluating particulate solids flow properties based on a solid extrusi…
