The resilience of a city confronted with a terrorist bomb attack is the background of the paper. The resilience strongly depends on vital infrastructure and the physical protection of people. The protection buildings provide in case of an external explosion is one of the important elements in safety assessment. Beside…
Nanocarriers offer several advantages in drug delivery including increased retention time in the body, the ability to solubilize hydrophobic cargo, and the ability to target specific tissues. These attributes have led to a large volume of research being dedicated to the development of novel nanocarriers and their use…
Template based protein structure prediction (commonly referred to as homology or comparative modeling) uses knowledge of solved structures to model a protein sequence's native or true fold. First, a parent structure is found and then a template structure is built by mapping the target sequence onto the parent structur…
The Helmholtz free energy, F and the entropy, S are related thermodynamic quantities with a special importance in structural biology. We describe the difficulties in calculating these quantities and review recent methodological developments. Because protein flexibility is essential for function and ligand binding, we…
Computational protein tertiary structure prediction has made significant progress over the last decade due to the advancement of techniques and the growth of sequence and structure databases. However, it is still not very easy to predict the accuracy of a given predicted structure. Predicting the accuracy, or quality…
Abstract {Mn(DHBQ)(H2O)2} (H2DHBQ = 2,5-dihydroxy-1,4-benzoquinone) was investigated by X-ray diffraction, thermogravimetry, sorption isotherm of water, and proton conductivity measurements. It showed a one-dimensional coordination-polymer structure with axial coordination waters, which is the first report on the crys…
To date, 146 different mutations in superoxide dismutase 1 (SOD1) have been identified in patients with familial amyotrophic lateral sclerosis (ALS). The mean age of disease onset in patients inheriting mutations in SOD1 is 45-47 years of age. However, although the length of disease duration is highly variable, there…
Abstract Zr-containing SBA-15 materials with hollow spherical morphology were synthesized via adding zirconium into SBA-15 synthesis solution and adjusting pH to about 4–5 with ammonia water. The hollow spherical mesoporous materials were observed in micron scale, and the shell thickness was about 100 nanometers. Zirc…
In the recent years, there has been a growing interest in the development of nanoparticles based targeting agents for the tumor diagnostics and therapeutics. This is because of their potential to detect the tumor and treat the diseased tissue at the cellular and molecular level. In this respect nanoscale magnetic mate…
The response of concrete structures subjected to shock and blast load involves a rapid transient phase, during which material breach may take place. Such an effect could play a crucial role in determining the residual state of the structure and the possible dispersion of the fragments. Modelling of the transient phase…
Abstract Reduction of bis(2-bromocyclohexenyl)diselenide, prepared from cyclohexeno-1,2,3-selenadiazole by the procedure of Meier et al., followed by reaction with cadmium chloride, yielded the novel single source Cd/Se precursor [Cd(SeC6H8Br)2], which upon thermolysis in a high boiling reaction medium formed CdSe qua…
A fast and cost-effective technique is applied for fabricating cobalt and nickel nanopillars on aluminium substrates. By applying an electrochemical process, the aluminium oxide barrier layer is removed from the pore bottom tips of nanoporous anodic alumina templates. So, cobalt and nickel nanopillars are fabricated i…
Highly ordered Ni nanotube and nanowire arrays were fabricated via electrodeposition. The Ni microstructures and the process of the formation were investigated using conventional and high-resolution transmission electron microscope. Herein, we demonstrated the systematic fabrication of Ni nanotube and nanowire arrays…
The successful use of picosecond-pulse free-electron-laser (FEL) radiation for the continuous-wave THz-range electron spin resonance (ESR) spectroscopy has been demonstrated. The combination of two linac-based FELs (covering the wavelength range of 4 - 250 $μ$m) with pulsed magnetic fields up to 70 T allows for multi-…
Based on his 50-year career in static high-pressure research, P. W. Bridgman (PWB) is the father of modern high-pressure physics. What is not generally recognized is that Bridgman was also intimately connected with establishing shock compression as a scientific tool and he predicted major events in shock research that…
Ni3C nanoparticles of about 40 nm have been studied experimentally to exhibit weak ferromagnetic (FM), spin-glass (SG) and paramagnetic (PM) properties. The freezing temperature of the SG phase at zero applied field is determined as, TF0 ~ 11.0 K. At T > TF0, a very weak ferromagnetism has been observed over a PM back…
We propose a generalized Dirac fermion description for the electronic state of graphene terminated by a zigzag edge. This description admits a specific spin-orbit coupling needed to preserve time-reversal invariance of the zigzag confinement, otherwise, for spinless particles, showing the parity anomaly typical of qua…
In this note, we show that the latest spin grating measurement of spin helix by Koralek {\em et al.} [Nature {\bf 458}, 610 (2009)] provides strong evidence of the infinite spin diffusion length of any spin polarization along the direction perpendicular to the effective magnetic field from the Dresselhaus and Rashba s…
Microelectronics has its back to the wall. One of the possible ways to pursue its development is the “bottomup” approach, whose philosophy can be enounced as follows : “grow the device you want where you want”. The unidimensionnal structures, and more precisely the semiconductor nanowires, belong to this topic. In the…
