Until the 1960s, liquids were generally regarded as either dense gases or disordered solids, and theoretical attempts at understanding their structures and properties were largely based on those concepts. Bernal, himself a crystallographer, was unhappy with either approach, preferring to regard simple liquids as ‘homo…
The main aim of the present work is to study the relation between microstructural features – such as local misorientations, grain orientation gradients and grain boundary structures – and thermomechanical treatment of hexagonal zirconium (Zr702α). Electron backscatter diffraction (EBSD) topological maps are used to an…
A systematic x-ray and neutron powder diffraction study of the giant tetragonality multiferroic (1−x) BiFeO3-(x) PbTiO3 have revealed that the compositions close to the morphotropic phase boundary present two different structural phase transition scenarios on cooling from the cubic phase: (i) cubic → tetragonal (T2) +…
Magneto-dielectric materials with matched permeability and permittivity are promising candidates as loading materials to reduce the physical dimensions of low-frequency antennas. In this study, NiCuZn ferrites were prepared by both the traditional final-stage sintering process and the two-step sintering process to obt…
The compounds containing lutetium and tungsten atoms have large effective atomic number (Zeff) and high stopping ability for high energy radiation because both lutetium and tungsten atoms are heavy with large atomic number. In order to obtain a new red-emitting phosphor with high efficiency for X-ray detection, the tr…
Electric-field-dependent in situ Raman studies have been carried out on chemically prepared graphene oxide. The Raman spectra show significant changes with increase in the applied electric field; in particular, the intensity of the G peak decreases with electric field. This behavior is typical for chemically or therma…
OBJECTIVES: For the last 20 years, the idea of alternative prevention strategies based on the use of topical vaginally products to inhibit HIV-1 infection in women has been established. The concept of a 'microbicide' product has been born out of the unavailability of a vaccine against HIV-1 and the problems of women i…
A well-defined poly(ethylene glycol) methyl ether-b-poly(lactic acid) copolymer (mPEG-PLA) featuring a new, Y-shaped, architecture with a hydroxyl functional group between the two blocks has been prepared and thoroughly characterized. The functional copolymer was then readily coupled to diglycolyl-cabazitaxel. The res…
In this work, we fabricate an oriented luminescent quantum dot (QD)-layered double hydroxide (LDH) nanocomposite material by the highly orderly and alternate assembly of trace CdTe QDs in dodecylbenzene sulfonate bilayer bunches on the organo-modified LDH exterior surfaces. Interestingly, the novel QD-LDH nanocomposit…
Using near-IR emitting photosensitizers, viz., zinc phthalocyanine (ZnPc), zinc naphthalocyanine (ZnNc), and BF 2 -chelated azadipyrromethene (azaBODIPY), donor–acceptor conjugates have been newly formed using the well-known metal–ligand axial coordination approach. To accomplish this task, the electron-deficient azaB…
Carboxymethyl cellulose (CMC) is produced commercially in a two-stage process consisting of a mercerization stage followed by an etherification stage. In this work, extended mercerization stages were used when producing CMC from a spruce dissolving pulp. Near infra-red (NIR) Fourier transform (FT) Raman spectroscopy w…
INTRODUCTION: The field of application for nanosized materials ranges from mere technical purposes to a growing field of applications in biomedicine. Among the different techniques and processes to produce these materials for encapsulation of reporter molecules and drugs, the miniemulsion process has been proven to be…
In spite of the extreme rise to the knowledge of nanotechnology in pharmaceutical sciences, there are currently limited experimental works studying the interactions between nanoparticles (NPs) and the biological system. Adjustment of size and surface area plays the main role in the reaction between NPs and cells leadi…
This paper summarizes the structural materials used in light water reactors (LWR), their historical degradation evolution vs. time, improvements and subsequent vulnerabilities discovered, and possible future degradation phenomena over long-term operation. Little was known about high-temperature water environments 50+…
Continuous updating of the genome sequence of Bacillus subtilis, the model of the Firmicutes, is a basic requirement needed by the biology community. In this work new genomic objects have been included (toxin/antitoxin genes and small RNA genes) and the metabolic network has been entirely updated. The curated view of…
The effect of Z r O 2 on the nucleation of lithium metasilicate crystals in lithium disilicate‐based multicomponent glasses of composition in wt% x Z r O 2 + (1 − ( x /100)) (73.82 S i O 2 + 3.99 K 2 O + 15.33 L i 2 O + 3.51 A l 2 O 3 + 3.35 P 2 O 5 ) with x = 0, 3, 4, 6, 8, and 12 was studied by combining the results…
We report on robust features of the longitudinal conductivity (σ(xx)) of the graphene zero-energy Landau level in the presence of disorder and varying magnetic fields. By mixing an Anderson disorder potential with a low density of sublattice impurities, the transition from metallic to insulating states is theoreticall…
Based on an analysis of the surface admittance of a plasmonic film with a substrate, we propose an ultrathin quarter-wave plate consisting of a periodic plane array of symmetrical L-shaped plasmonic antennas. The period, which determines the coupling among L-shaped antennas, is an important parameter for optimizing th…
In this paper, the influence of variable molar ratios between reducing and loading agents (1:100, 1:50, 1:20, 1:10, 1:5, 1:2, 1:1, 2:1) and between protective and loading agents (0.3:1, 0.75:1, 1.5:1, 3:1, 7.5:1, 30:1, 75:1) in the synthesis of silver nanoparticles by chemical reduction has been evaluated to obtain mu…
A new multistimuli-responsive luminescent material, [Cu 8 I 8 (4-dpda) 6 ] n ( 1 ) (4-dpda=4-(diphenylphosphino)- N,N -dimethylaniline), has been obtained by combining inorganic Cu 8 I 8 clusters and organic ligands 4-dpda, providing a novel in-/organic hybrid approach as an interesting alternative to all-organic appr…
