Magnetic resonance imaging (MRI) has become an indispensable tool in the diagnosis and treatment of many diseases, especially cancer. However, the poor sensitivity of MRI relative to other imaging modalities, such as PET, has hindered the development and clinical use of molecular MRI contrast agents that could provide…
In a previous report, a new method for quantitative phase analysis (QPA) of multi-component mixtures using a conventional X-ray powder diffractometer was proposed. The formula for deriving weight fractions of individual crystalline phases presented therein includes sets of observed integrated intensities measured in a…
Abstract Display glasses meet the demands of the flat panel display industry vis‐à‐vis their composition, flatness, and forming processes. Here, we report the high‐resolution time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) characterization of Corning ® EAGLE XG ® , a widely used display glass, and subsequent…
In this work it is shown that CaZnOS:Eu 2+ has no Eu 2+ emission even at low temperature. The observed and earlier reported red emission originates from a CaS:Eu 2+ impurity phase. By means of washing the as-prepared samples with diluted nitride acid, we were able to remove the CaS impurity phase and study the Eu2+ em…
We perform pulsed optically detected electron spin resonance to measure the DC magnetic field sensitivity and electronic spin coherence time T2 of an ensemble of near-surface, high-density nitrogen-vacancy centers engineered to have a narrow magnetic resonance linewidth. Combining pulsed spectroscopy with dynamic nucl…
Abstract The structure and bonding of a Pr‐doped boron cluster (PrB 7 − ) are investigated using photoelectron spectroscopy and quantum chemistry. The adiabatic electron detachment energy of PrB 7 − is found to be low [1.47(8) eV]. A large energy gap is observed between the first and second detachment features, indica…
To improve the therapeutic index of cisplatin (CDDP), we present here a new paradigm of drug-induced self-assembly by harnessing phosphato-platinum complexation. Specifically, we show that a phosphato-platinum cross-linked micelle (PpY/Pt) can be generated by using a block copolymer methoxy-poly(ethylene glycol)- bloc…
Abstract The absorption spectra of monolayer tinene in perpendicular electric fields are studied by the tight-binding model. There are three kinds of special structures, namely shoulders, logarithmical symmetric peaks and asymmetric peaks in the square-root form, corresponding to the optical excitations of the extreme…
The thermal and light‐induced magnetic properties of a family of metal‐diluted spin‐crossover complexes, [Fe x M 1– x (phen) 2 (NCS) 2 ] (phen = 1,10‐phenantholine and M = Ni II , Cd II ), are reported and compared to previous results obtained for the same series but with Zn II ions used to substitute Fe II ions; the…
Over the last decades, power disturbances have become an important factor on the increase throughout electrical networks, which can exert an important influence over power quality ratios. Amongst them, it is worth mentioning ferroresonance, which is a special case of resonance involving non-linear inductances that mai…
This study uses a reactive extrusion for the grafting of maleic anhydride on polylactic acid in order to form polylactic acid grafted maleic anhydride that serves as a compatibilizer between polylactic acid and carbon fiber. The effects of different ratios of the free radical initiator to maleic anhydride as well as t…
We investigate the effects of hydrophobic silica nanoparticles (SNs) on blue-phase liquid crystals (BPLCs). The optical microscope and reflection spectra observation reveal that a tiny hydrophobic SN dopant stabilises the BPLC phase, and widens the temperature range of the BP I phase. Furthermore, the doped dilute SNs…
Using ab initio molecular dynamics, we present a systematic study of structural and transport properties of liquid Al90Zn10 and Al83Zn10Cr7 alloys. In the liquid phase, we find that Cr additions promote the formation of a heterogeneous local ordering characterized by a strong five-fold symmetry (icosahedral short-rang…
Silica coating is widely used for protecting nanoparticles from aggregation and in transforming them into functional nanoparticles of 10–100 nm size. However, synthesis of silica-coated nanoparticles of <50 nm size with low surface charge, high colloidal stability, and minimum nonspecific interaction with the bioenvir…
Understanding the microscopic mechanism of magnetoelectric coupling is of fundamental importance for the rational design of multiferroics. Herein, the magnetoelectric coupling effect in the metal-organic frameworks of [NH2(CH3)2]n[FeIIIFeII(HCOO)6]n (1) was investigated, respectively, through measuring the dielectric…
Magnesium phosphate ceramics are a class of acid–base cements for bioengineering and civil engineering applications. We report on quasielastic neutron scattering results focusing on the evolution of the state of water in the system during the setting reaction, to shed light on the reaction mechanisms and the nature of…
Abstract Proton‐conductive electrospun nanofibers are promising potential materials for several advanced technological applications such batteries, sensors, and fuel cells. In this work, we prepared poly(vinyl butyral)/polyaniline ( PVB / PANI ) nanofibers via electrospinning and determined their proton conductivities…
Abstract Estimation of postmortem interval (PMI) is a central role in medico-legal identification. Analysis of vitreous potassium ions (K + ) concentration is frequently used by forensic workers to estimate PMI. This paper describes interdisciplinary research to introduce fluorescence sensing techniques into forensic…
Supersaturating formulations have become a popular approach to address the issue of inadequate aqueous solubility for small molecules. Given that prevention of nucleation may not be always possible, it is of particular interest to control crystal growth from supersaturated solutions in order to maximize the extent of…
Electroluminescence from individual carbon nanotubes within split-gate devices is investigated. By characterizing the air-suspended nanotubes with photoluminescence spectroscopy, chirality is identified and electroluminescence peaks are assigned. We observe electroluminescence linewidths comparable to photoluminescenc…
