Metastable α"-Fe16N2is considered to be a good candidate as a semi-hard magnetic material with high saturation magnetization. To obtain a higher coercivity Hc, it is necessary to improve the magnetocrystalline anisotropy of α"-Fe16N2. For this purpose, many theoretical calculations based on substitution of Fe with oth…
We reanalyze the results from a set of terminal ballistics tests in which large limestone targets were impacted by similarly shaped rigid projectiles having different sizes. Our first goal is to show that the data in terms of penetration depths as a function of impact velocity can be accounted for by a model in which…
An instrumented 1:70 scale model underground tunnel, located below a free water body, was subjected to explosions in centrifuge model tests. Utilising centrifuge scaling relations, each test at 70g modelled the effects of an explosion due to approximately 0.9 t of trinitrotoluene equivalent. The explosives were locate…
The equilibrium solubility of gliclazide (3) in {Transcutol (1) + water (2)} mixtures at several temperatures was reported in the literature. However, no deep attempt was made to correlate gliclazide solubility with the composition of the aqueous-cosolvent mixtures. Moreover, no apparent thermodynamic calculations for…
The formation of an ultrathin aluminum oxide film at the ${\mathrm{Fe}}_{0.85}{\mathrm{Al}}_{0.15}$(110) surface (${\mathrm{A}}_{2}$ random alloy) has been studied by a variety of surface-sensitive techniques (x-ray photoemission, low-energy electron diffraction, surface x-ray diffraction, and scanning tunneling micro…
Quasi-zero-dimensional antiferromagnets with weakly coupled clusters of multiple spins can provide an excellent platform for exploring exotic quantum states of matter. Here, we report the synthesis and the characterization of a copper-based insulating antiferromagnet, K(NbO)Cu 4 (PO 4 ) 4 . Single-crystal X-ray diffra…
Malignancies represent a burden for the health system worldwide. Treating them represents a challenge through the prism of the cancer cell behaviour and the serious systemic side effects that usually occur. Both traditional (chemotherapy, radiotherapy and surgery) and associated therapies (immunotherapy and hormone th…
This chapter provides a comprehensive, up-to-date understanding of how to toughen epoxy resins via rubber modification. This includes a brief review of recent developments in epoxy toughening, a brief overview of the use of effective experimental and numerical tools for studying the fracture behavior of epoxy systems,…
Abstract The vibrational dynamics of the iron centres in 1D and 3D spin crossover Fe(II) 4-alkyl-urea triazole chains have been investigated by synchrotron based nuclear inelastic scattering. For the 1D system, the partial density of phonon states has been modelled with density functional theory methods. Furthermore,…
The behavior of S235 metal, a general purpose metal construction material in Senegal, has been studied in perchloric acid solution in the presence of gum arabic from Senegal as a corrosion inhibitor. The protective power of this compound has been evaluated by electrochemical methods (stationary polarization curves and…
Controlled drug release in formulation is an important area of research. Formulations using crospovidone as super-disintegrants to achieve immediate release once it reaches the ileo- cecal region is relevant. The Eudragit L30D pH dependent polymer that allows drug release after a lag time of 4-5 hrs to achieve desired…
A study of the olfactory organ, with marked observation on cellular morphology of neuroepithelium was carried out in riverine catfish Ailia coila (Hamilton, 1822) using light and scanning electron microscopy. The elongated olfactory rosette within olfactory chamber was made up of 16 ± 2 leaf lets, the lamellae which c…
Preparation of MgO and Mg0.95Zn0.05O nanomaterials using self-propagating combustion method are done to investigate the effect of doping on the band gap energy. The synthesis condition has been optimized to obtain pure MgO and Mg0.95Zn0.05O materials which confirmed by XRD. FESEM results shows agglomeration of crystal…
Wear-resistant coatings can reduce the high economic damage caused by wear processes. In this study, various protective layers based on the alloy X400CrVMo17-15-2 were investigated. Commonly, the prealloyed metal powder is used for plasma transferred arc powder surfacing. However, in this work, the cost-efficient hard…
Abstract Datasets from single-molecule experiments often reflect a large variety of molecular behaviour. The exploration of such datasets can be challenging, especially if knowledge about the data is limited and a priori assumptions about expected data characteristics are to be avoided. Indeed, searching for pre-defin…
Abstract One of the ways to increase natural gas production is to conserve and/or intensify existing wells with their subsequent development. They are characterized by a high content of highly mineralized water, which leads to an increased risk of hydrate formation and internal corrosion. The issue of the formation of…
The luminescence properties Dy3+, Eu3+ and Sm3+ doped magnesium sodium borate glasses were investigated. The glasses samples containing the composition 30MgO-70Na2B4O7.10H2O-xRE2O3 (where RE = Dy3+, Eu3+, and Sm3+, x = 0.1, 0.5, and 1.0 mol %) are prepared by the conventional melt quenching technique. The optical prop…
We demonstrate that the mechanical response of ice templated nanocomposite scaffolds prepared from ellipsoidal hematite particles is determined by both the particle aspect ratio and the interaction between the particles and the matrix polymer. We ice template aqueous dispersions of hematite particles, polyethyleneimin…
Pyrazinamide (PZA) is a component of first-line drugs, active against latent Mycobacterium tuberculosis (MTB) isolates. The prodrug is activated into the active form, pyrazinoic acid (POA) via pncA gene-encoded pyrazinamidase (PZase). Mutations in pncA have been reported, most commonly responsible for PZA-resistance i…
Abstract Nonmagnetic graphene-based van der Waals heterotrilayers exhibit peculiar electronic features such as energetically and/or spatially resolved Dirac rings/cones. Here, using first-principles calculations we study the effect of magnetic proximity effect and mirror symmetry of antiferromagnetic CrAs 2 monolayer…
