The Stability of Copper Oxo Species in Zeolite Frameworks
Authors: Vilella Laia , Studt Felix 
Published: March 2016

AbstractCu‐exchanged zeolites are promising heterogeneous catalysts, as they provide a confined environment to carry out highly selective reactions. However, the knowledge of how the zeolite framework and the location of Al atoms therein affect the adsorption of copper species is still not well understood. In this work, DFT was used to investigate the adsorption of potential Cu oxo active species suggested in the literature [Cu(η2‐O2), Cu(µ‐O)Cu, and Cu2O2] into zeolites with different pore sizes and shapes (AFI, CHA, TON, MOR, and MFI). The calculations revealed that both monomeric and dimeric Cu oxo species bind strongly to the O atoms of the lattice. For the monometallic species similar adsorption energies are obtained with the different zeolite frameworks, whereas an optimum Al–Al distance is required for the dimeric species.
Elastocaloric and Piezocaloric Effects in Lead Zirconate Titanate Ceramics
Authors: Patel Satyanarayan , Chauhan Aditya , Vaish Rahul 
Published: March 2016

AbstractThis study demonstrates that stress‐driven caloric effects can be obtained in bulk lead zirconate titanate (PZT) ceramics. The strain and polarization gradient have been utilized to determine the elastocaloric and piezocaloric effects, respectively. Almost similar values are obtained up to the phase transition point (390 K), beyond which a large difference is observed. A peak elastocaloric temperature change of 1.9 K was obtained for an applied compressive stress of 0–400 MPa (450 K). Conversely, a maximum piezocaloric effect of 1.7 K is observed for stress values of 0–300 MPa (390 K). Overall, this study allows one to easily differentiate between caloric effects arising from polarization and strain changes.

ABSTRACT

Rheumatoid arthritis (RA), an autoimmune inflammatory disorder, results in persistent synovitis with severe bone and cartilage destruction. Bisphosphonates (BPs) are often utilized in RA patients to reduce bone destruction and manage osteoporosis. However, BPs, especially at high doses, are associated with osteonecrosis of the jaw (ONJ). Here, utilizing previously published ONJ animal models, we are exploring interactions between RA and ONJ incidence and severity. DBA1/J mice were divided into four groups: control, zoledronic acid (ZA), collagen-induced arthritis (CIA), and CIA-ZA. Animals were pretreated with vehicle or ZA. Bovine collagen II emulsified in Freund's adjuvant was injected to induce arthritis (CIA) and the mandibular molar crowns were drilled to induce periapical disease. Vehicle or ZA treatment continued for 8 weeks. ONJ indices were measured by micro-CT (µCT) and histological examination of maxillae and mandibles. Arthritis development was assessed by visual scoring of paw swelling, and by µCT and histology of interphalangeal and knee joints. Maxillae and mandibles of control and CIA mice showed bone loss, periodontal ligament (PDL) space widening, lamina dura loss, and cortex thinning. ZA prevented these changes in both ZA and CIA-ZA groups. Epithelial to alveolar crest distance was increased in the control and CIA mice. This distance was preserved in ZA and CIA-ZA animals. Empty osteocytic lacunae and areas of osteonecrosis were present in ZA and CIA-ZA but more extensively in CIA-ZA animals, indicating more severe ONJ. CIA and CIA-ZA groups developed severe arthritis in the paws and knees. Interphalangeal and knee joints of CIA mice showed advanced bone destruction with cortical erosions and trabecular bone loss, and ZA treatment reduced these effects. Importantly, no osteonecrosis was noted adjacent to areas of articular inflammation in CIA-ZA mice. Our data suggest that ONJ burden was more pronounced in ZA treated CIA mice and that RA could be a risk factor for ONJ development. © 2016 American Society for Bone and Mineral Research.

Published: March 2016

AbstractBACKGROUNDPeptones are one of the most expensive components of microbial culture media. The present study was performed to produce microbial peptone from sheep wool using a new chemical process.RESULTSWool peptone (WP) was found to have high protein (67.8 g per 100 g) and ash (29.2 g per 100 g) contents. Glutamic acid was the most abundant amino acid in WP with a content of 8175 mg per 100 g). Wool peptone (WP) also had a high content (5042 mg per 100 g) of cystine, a sulphur‐containing amino acid. Optimal concentration of WP was determined as 5 g L−1 for the fungi and 6 g L−1 for the bacteria. Staphylococcus aureus showed very poor growth performance in WP medium. Growth performances of Saccharomyces cerevisiae, Bacillus subtilis and Penicillium chrysogenum were at moderate levels in WP medium. The best growth performance for Aspergillus niger was observed in WP medium with a biomass production of 8.17 g L−1. Second best growth performance for Escherichia coli was achieved with WP among the tested peptones.CONCLUSIONWool peptone (WP) was shown to be a good growth substrate, especially for A. niger and E. coli. This is the first investigation on use of wool as peptone source or substrate for microorganisms. © 2016 Society of Chemical Industry

PurposeWe present a breast phantom designed to enable quantitative assessment of measurements of T1 relaxation time, apparent diffusion coefficient (ADC), and other attributes of breast tissue, with long‐term support from a national metrology institute.Materials and MethodsA breast phantom was created with two independent, interchangeable units for diffusion and T1/T2 relaxation, each with flexible outer shells. The T1 unit was filled with corn syrup solution and grapeseed oil to mimic the relaxation behavior of fibroglandular and fatty tissues, respectively. The diffusion unit contains plastic tubes filled with aqueous solutions of polyvinylpyrrolidone (PVP) to modulate the ADC. The phantom was imaged at 1.5T and 3.0T using magnetic resonance imaging (MRI) scanners and common breast coils from multiple manufacturers to assess T1 and T2 relaxation time and ADC values.ResultsThe fibroglandular mimic exhibited target T1 values on 1.5T and 3.0T clinical systems (25–75 percentile range: 1289 to 1400 msec and 1533 to 1845 msec, respectively) across all bore temperatures. PVP solutions mimicked the range of ADC values from malignant tumors to normal breast tissue (40% PVP median: 633 × 10−6 mm2/s to 0% PVP median: 2231 × 10−6 mm2/s) at temperatures of 17–24°C. The interchangeable phantom units allowed both the diffusion and T1/T2 units to be tested on the left and right sides of the coil to assess any variation.ConclusionThis phantom enables T1 and ADC measurements, fits in a variety of clinical breast coils, and can serve as a quality control tool to facilitate the standardization of quantitative measurements for breast MRI.

On the Modeling of Acrylic Acid Copolymerization in an Aqueous Solution: A Modular, Integrated Approach
Authors: Meimaroglou Dimitrios , Chevrel Marie‐Claire , Hoppe Sandrine , Durand Alain , Falk Laurent , Wilson James , Ferlin Patrick 
Published: March 2016

A complete mathematical model of the free‐radical copolymerization of acrylic acid in an aqueous solution, taking place in a pilot‐scale tubular reactor equipped with static mixers, is presented. The developed kinetic/reactor model is numerically integrated in terms of a coupled deterministic–stochastic numerical approach that combines the advantages of speed, efficiency, and increased predictive capabilities. A series of experimental measurements on the monomer conversion and the molecular weight characteristics of the produced copolymer, under a wide range of process conditions, are used for the identification of the kinetic model parameters while a thorough analysis of the compositional characteristics of the produced copolymers is also carried out in terms of a series of bivariate distributed properties.

Modeling of the Methyl Methacrylate Atom Transfer Radical Suspension Polymerization Process: Polymerization and Particle Kinetics
Authors: Xie Le , Luo Zheng‐Hong 
Published: March 2016

In this work, a mathematical model is developed to characterize the batch atom transfer radical suspension polymerization (batch suspension ATRP). For the first time, the morphological and molecular properties of particles, as well as their dynamics in methyl methacrylate ATRP can be simultaneously simulated by solving the model that consists of ATRP kinetic equations, moment equations, a phase equilibrium equation for calculating equilibrium monomer distributions in various phases, and a particle population balance model. The proposed model is verified using the open experimental data. Based on the verified model, two key operating factors including the ratios of monomer to initiator and water to monomer are studied in order to investigate the batch suspension ATRP kinetics. In addition, the model is also used to predict the droplet/particle size distribution. The effects of breakage rate, coalescence rate, and agitation speed on the droplet volume density distribution and the Sauter mean diameter are discussed in details. The simulated results demonstrate that the coupled model can describe the batch suspension ATRP kinetics and its droplet kinetics.

Published: March 2016

PurposeCardiac MRI at 7T suffers from contrast heterogeneity that can be mitigated with parallel transmission (pTX) and, when performed during breath‐hold, from a limited number of slices that can be multiplied with multiband (MB) radiofrequency pulses by simultaneous excitation of multiple slices (SMS). The goal of this study was to apply both approaches simultaneously.MethodsUsing a 16‐channel transmit/receive body coil, pTX SMS was applied with/without CAIPIRINHA with a modified gradient echo cine sequence. Different calibration schemes were investigated for the slice‐GRAPPA reconstruction kernels as a function of the cardiac cycle.ResultsExcellent slice separation for MB = 2 was achieved with CAIPIRINHA, with slice leakage values below 3% for 99% of all voxels. A critical finding of this study was the variation of the MB leakage factor in the heart by as much as 30% throughout the cardiac cycle, which was reduced greatly when reconstruction kernels were calibrated on multiple cardiac phases. Acceptable results were still obtained when applying further acceleration with MB = 3 in combination with in‐plane GRAPPA. In one case, two‐spoke pulses were compared with one‐spoke pulses, resulting as expected in improved homogeneity.ConclusionpTX SMS imaging at 7T can address contrast heterogeneity while allowing larger slice coverage in cardiac MRI performed under breath‐hold.

Fabrication and characterization of biopolymer nanocomposites from natural resource materials
Authors: Ramesan M.T. , Surya K. 
Published: March 2016

In this study, nanocomposites of cashew tree gum (CTG) encapsulated nano‐magnetite (Fe3O4) was prepared and characterized by FTIR, UV–visible, X‐ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), magnetic and conductivity measurements. The characteristic absorption peaks in FTIR and UV–vis spectra of CTG was found to be shifted to higher wave numbers in CTG/Fe3O4 composite, which is due to the intermolecular interaction between nanoparticles and the CTG. The XRD patterns indicated that amorphous region of gum was decreased by the addition of metal oxide nanoparticles. SEM images show that nano‐Fe3O4 was uniformly dispersed in the cashew gum segments. DSC analysis revealed that the glass transition temperature and melting behavior of composites were higher than those of the pure gum. TGA results indicated that the thermal decomposition temperature of the composite increases with the increase in concentration of metal oxide nanoparticles. The magnetic properties studied by a vibrating sample magnetometer indicate that electromagnetism of CTG/Fe3O4 nanocomposites were superparamagnetic. The values of saturation of magnetization (Ms) and remanence (Mr) increases, while the coercivity (Hc) decreased with increase in Fe3O4 content in the composite. The AC electrical conductivity of the nanocomposites was significantly increased with the increase in Fe3O4 content in the nanocomposite. Due to the ordered structure of polymer composite, the dielectric constant and dielectric loss tangent (tan δ) of nanocomposites were also increased with increase in the concentration of nanoparticles.
