Thermal, electrical, and mechanical properties of polyethylene–graphene nanocomposites obtained by in situ polymerization
Authors: Fim Fabiana de C. , Basso Nara R. S. , Graebin Ana P. , Azambuja Denise S. , Galland Griselda B. 
Published: August 2012

AbstractIn this study, we investigated the thermal, dynamic mechanical, mechanical, and electrical properties of polyethylene (PE)–graphene nanosheet (GNS) nanocomposites, with GNS amounts from 0 to 20 wt %, prepared by in situ polymerization. The thermal stability was evaluated by thermogravimetric analysis (TGA) and showed that the addition of GNSs to the polyolefin matrix increased the onset degradation temperature by 30°C. The electrical conductivity, measured by the impedance technique, presented a critical percolation threshold of 3.8 vol % (8.4 wt %) of GNS. A slight decrease in the tensile strength was found. On the other hand, dynamic mechanical analysis showed an increase in the storage modulus of the nanocomposites compared with that of neat PE. The glass‐transition temperature value increased from −111°C (neat PE) to −106°C (PE/6.6 wt % GNS). All of these results show that PE became stiffer and thermally more stable and could be transformed from an insulator to a semiconductor material in the presence of GNSs. © 2012 Wiley Periodicals, Inc.

Effect of the type of clay organo‐modifier on the morphology, thermal/mechanical/impact/barrier properties and biodegradation in soil of polycaprolactone/clay nanocomposites
Authors: Ludueña L. N. , Vázquez A. , Alvarez V. A. 
Published: August 2012

AbstractThe effect of addition of unmodified (CNa+) and modified (C30B and C20A) montmorillonites on the performance of polycaprolactone (PCL) based nanocomposites prepared by melt intercalation was studied. The study covers morphological and thermal aspects, mechanical and barrier properties and also biodegradability, which are important for packaging applications. Particular effort was made to find the main characteristics of the clays responsible for the final clay dispersion degree inside the nanocomposite. The most hydrophobic reinforcement (demonstrated by water adsorption tests) also showed the strongest thermal stability (shown by thermogravimetrical analysis) and the larger basal spacing (calculated by X‐ray diffractometry (XRD)), which were the main characteristics that led to the best clay dispersion degree inside the PCL matrix (demonstrated by XRD and Transmission Electron Microscopy (TEM)). The findings demonstrate that a biodegradable polymer/clay nanocomposite with enhanced mechanical, impact, and barrier properties was obtained. © 2012 Wiley Periodicals, Inc. J. Appl. Polym.

Nitrous‐Acid‐Mediated Synthesis of Iron–Nitrosyl–Porphyrin: pH‐Dependent Release of Nitric Oxide
Authors: Bhuyan Jagannath , Sarkar Sabyasachi 
Published: August 2012

AbstractTwo iron–nitrosyl–porphyrins, nitrosyl[meso‐tetrakis(3,4,5‐trimethoxyphenylporphyrin]iron(II) acetic acid solvate (3) and nitrosyl[meso‐tetrakis(4‐methoxyphenylporphyrin]iron(II) CH2Cl2 solvate (4), were synthesized in quantitative yield by using a modified procedure with nitrous acid, followed by oxygen‐atom abstraction by triphenylphosphine under an argon atmosphere. These nitrosyl porphyrins are in the {FeNO}7 class. Under an argon atmosphere, these compounds are relatively stable over a broad range of pH values (4–8) but, under aerobic conditions, they release nitric oxide faster at high pH values than that at low pH values. The generated nitric‐oxide‐free iron(III)–porphyrin can be re‐nitrosylated by using nitrous acid and triphenylphosphine. The rapid release of NO from these FeII complexes at high pH values seems to be similar to that in nitrophorin, a nitric‐oxide‐transport protein, which formally possesses FeIII. However, because the release of NO occurs from ferrous–nitrosyl–porphyrin under aerobic conditions, these compounds are more closely related to nitrobindin, a recently discovered heme protein.
Robust H∞ Control in Fast Atomic Force Microscopy
Authors: Chuang Ning , Petersen Ian R. , Pota Hemanshu R. 
Published: August 2012

AbstractThis paper develops a robust H
∞ method for fast tracking position control problems arising in an atomic force microscope (AFM). A commercial type NT‐MDT AFM is used to generate 3D images of scanned material surfaces at high speeds and accuracies. A major component of this AFM is a piezoelectric tube actuator used for position control in three directions. Due to the nature of the piezoelectric actuator, there is nonlinear hysteresis present which affects the AFM scanning qualities. The original commercial AFM uses traditional proportional‐integral‐derivative position control and can only obtain good quality images for scanning rates under about 20 Hz in both the x and y directions.In this paper, a robust H
∞ controller is designed based on a physical model of the AFM piezoelectric tube positioner in the x and y directions. On the electrical side of the positioning system, external capacitors are connected in series with the x and y contacts of the piezoelectric tube to provide measured voltages which are proportional to the charge on the actuator. The parameters for a nonlinear model are obtained from measurements of the system frequency response and time domain response. This model also takes into account the time delay resulting from the sensor electronics. This nonlinear model is represented as a linear uncertain system model with norm bounded uncertainty. The uncertain system model is used to design a robust H
∞ tracking controller for the AFM scanning system. Experimental results show that the robust H
∞ controller can improve the AFM scanning quality and increase the scanning speed significantly. The controller performs well in tracking a given reference scanning signal with frequencies up to 125 Hz.
Weakening of hurricanes via marine cloud brightening (MCB)
Authors: Latham John , Parkes Ben , Gadian Alan , Salter Stephen 
Published: August 2012

AbstractThis paper examines the potential to cool ocean surface waters in regions of hurricane genesis and early development. This would be achieved by seeding, with copious quantities of seawater cloud condensation nuclei (CCN), low‐level maritime stratocumulus clouds covering these regions or those at the source of incoming currents. Higher cloud droplet density would increase these clouds' reflectivity to incoming sunlight, and possibly their longevity. This approach is therefore a more localized application of the marine cloud brightening (MCB) geoengineering technique promoting global cooling. By utilizing a climate ocean/atmosphere coupled model, HadGEM1, we demonstrate that—subject to the satisfactory resolution of defined but unresolved issues—judicious seeding of maritime stratocumulus clouds might significantly reduce sea surface temperatures (SSTs) in regions where hurricanes develop. Thus artificial seeding may reduce hurricane intensity; but how well the magnitude of this effect could be controlled is yet to be determined.We also address the important question as to how MCB seeding may influence precipitation. GCM modelling indicates that the influence of seeding on undesirable rainfall reductions depends on its location and magnitude. Much more work on this topic is required.

Hedgehog signalling as an antagonist of ageing and its associated diseases
Authors: Dashti Monireh , Peppelenbosch Maikel P. , Rezaee Farhad 
Published: August 2012

AbstractHedgehog is an important morphogenic signal that directs pattern formation during embryogenesis, but its activity also remains present through adult life. It is now becoming increasingly clear that during the reproductive phase of life and beyond it continues to direct cell renewal (which is essential to combat the chronic environmental stress to which the body is constantly exposed) and counteracts vascular, osteolytic and sometimes oncological insults to the body. Conversely, down‐regulation of hedgehog signalling is associated with ageing‐related diseases such as type 2 diabetes, neurodegeneration, atherosclerosis and osteoporosis. Hence, in this essay we argue that hedgehog signalling is not only important at the start of life, but also constitutes an important anti‐geriatric influence, and that enhanced understanding of its properties may contribute to developing rational strategies for healthy ageing and prevention of ageing‐related diseases.Also watch the Video Abstract
Patients with small left ventricular size undergoing balloon aortic valvuloplasty have worse intraprocedural outcomes

AbstractObjectivesTo evaluate the impact of left ventricular (LV) chamber size on procedural and hospital outcomes of patients undergoing aortic valvuloplasty.BackgroundBalloon aortic valvuloplasty (BAV) is used as an integral step during transcatheter aortic valve implantation. Patients with small, thickened ventricles are thought to have more complications during and following BAV.MethodsRetrospective study of consecutive patients with severe, symptomatic calcific aortic stenosis who underwent retrograde BAV at Massachusetts General Hospital. We compared patients with left ventricular end‐diastolic diameters (LVEDD) <4.0 cm (n = 31) to those with LVEDD ≥4.0 cm (n = 78). Baseline and procedural characteristics as well as clinical outcomes were compared. Multivariate logistic regression was used for the adjusted analysis.ResultsPatients with smaller LV chamber size were mostly women (80.7% vs. 19.4%, P < 0.01) and had a smaller body surface area (BSA), (1.61 ± 0.20 m2 vs. 1.79 ± 0.25 m2, P < 0.01). Patients with smaller LV chamber size had higher ejection fractions and thicker ventricles. Otherwise, baseline characteristics were similar. The intraprocedural composite of death, cardiopulmonary arrest, intubation, hemodynamic collapse, and tamponade was higher for patients with LVEDD < 4.0 cm (32.3% v. 11.5%, P = 0.01). Adjusting for age, gender, BSA, LV pressure, and New York Heart Association class, LVEDD < 4.0 cm remained an independent predictor of procedural (OR 5.1, 95% CI 1.4–18.2) and in‐hospital complications (OR 3.8, 95% CI 1.2–11.6).ConclusionsCompared to patients undergoing BAV with LVEDD ≥4.0 cm, those with smaller LV chambers had worse procedural and in‐hospital outcomes. © 2012 Wiley Periodicals, Inc.
Early percutaneous valve failure within bioprosthetic tricuspid tissue valve replacements

Published: August 2012

ObjectiveTo describe the cases of percutaneous valve failure following implantation of the Medtronic Melody™ and the Edwards Sapien™ valve in the tricuspid position. Background: There have been recent reports of the use of percutaneously delivered valves to manage failing bioprosthetic tricuspid valves. Total patient numbers remain small and follow‐up times are limited.MethodsWe describe four procedures in three patients from two centers where implantation of percutaneous valves within the scaffold of a bioprosthetic tricuspid valve was technically successful but there was early valve failure.ResultsIn all cases, immediate results suggested excellent valve function; however, valve failure occurred early in three and later in one. Two patients elected for valve explantation and surgical placement of a further tricuspid valve. The third patient underwent a second percutaneous valve‐in‐valve procedure though this valve is also showing early signs of failure.ConclusionsTranscatheter placement of percutaneous valves in the tricuspid position is technically a relatively straightforward procedure but early valve failure raises some concerns about the viability of the valve in this position, at least in some patients. © 2013 Wiley Periodicals, Inc.
