Influence of the notch‐sharpening technique on styrene–acrylonitrile fracture behavior
Authors: Martínez A. B. , Salazar A. , León N. , Illescas S. , Rodríguez J. 
Published: May 2016

ABSTRACTThe Centre Català del Plàstic and Universidad Rey Juan Carlos laboratories joined forces to investigate the effect of the notch‐sharpening technique on the fracture parameters of styrene–acrylonitrile. Contact notch‐sharpening techniques, such as razor tapping, razor sliding, and razor broaching, and a noncontact procedure, femtolaser, were analyzed. The fracture values of the samples with notches sharpened via contact techniques were divided into two groups: one with pop‐in and the other with no pop‐in in the load–displacement records; this resulted in the lowest and highest fracture toughnesses, respectively. The fracture parameters of the specimens with notches sharpened via a femtolaser were between those of the samples with notches sharpened via contact procedures in which pop‐in occurred and those in which it did not. To explain these results, the crack front of the nontested specimens after sharpening was investigated in depth, we identified the type of damage and measured its size and the crack tip radii. The morphology of the crack front was related to the fractographic study. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43775.
N‐Boc‐Indolylbenzothiadiazole Derivatives: Efficient Full‐Color Solid‐State Fluorescence and Self‐Recovering Mechanochromic Luminescence

Published: May 2016

AbstractHerein, the solid‐state emission with good fluorescence quantum yields of N‐Boc‐indolylbenzothiadiazoles as a new class of fluorophores is described. Their solid‐state emission covers the wide range of the visible spectrum and the emission color can be tuned easily by changing the substituents on the two heteroaromatic rings. Among these, 3‐methylindolyl derivatives exhibit moreover autonomously self‐recovering mechanochromic luminescence, whereby the original solid‐state emission could be recovered spontaneously at room temperature after exposure to a mechanical stimulus. The emission color, as well as the recovery time for the color change could be tuned via the introduction of different substituents on the benzothiadiazole ring. We propose that the mechanism of the autonomously self‐recovering mechanochromic luminescence of 3‐methylindolylbenzothiadiazoles is based on a partial amorphization of the crystals upon exposure to the mechanical stimulus, followed by autonomous recovering in the form of recrystallization.
Experimental Implementation of New Sliding Mode Control Law applied To a DC–DC Boost Converter

Published: May 2016

AbstractThe real implementation of sliding mode controllers (SMCs) to a DC–DC boost converter is a challenge due to the nonminimum phase behavior of these kinds of converters and the SMCs chattering problem. In this paper, new integral sliding mode control laws with linear and proposed nonlinear sliding surfaces are developed to overcome these problems. An experimental comparative study between these SMCs and the classical SMC applied for a DC–DC boost converter is presented.

AbstractUniversal access to modern energy is required if the world is to reduce poverty and enable sustainable development. Energy poverty is the lack of access to safe and efficient energy carriers. It affects more than 1.3 billion people without electricity and 2.7 billion without appropriate cooking facilities and fuels, particularly in sub‐Saharan Africa (SSA). Under these conditions, people rely on traditional biomass to fulfil basic needs. Traditional biomass use causes death and disease associated with indoor air pollution, high labor demands to obtain biomass, and environmental damage due to deforestation. This paper analyzes the potential for modern energy production based on sugarcane in SSA. A standard, business‐as‐usual (BAU), sugar‐based project is explored vis‐à‐vis more aggressive scenarios for producing modern energy, including electricity, ethanol, and solid fuel pellets. All scenarios considered are based on a single sugarcane mill processing one million tonnes of cane per year, grown in an area of 15 000 hectares. Our simulations show that over 210 000 households could be served with electricity and other 31 000 with modern cooking fuels under the scenarios examined. Less dependence on traditional biomass may also spare wooded environments from deforestation. However, harnessing modern energy from sugarcane does not come without challenges. Economic pitfalls (e.g. investment costs and affordability) coupled with poor political environments are among the main obstacles. Nevertheless, encouraging local and regional trends proved bioenergy a feasible way out of energy poverty and an alternative to sustainable development. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd

Published: May 2016

AbstractObjectivesTick‐borne encephalitis (TBE) is an emerging flaviviral zoonosis in Central and Eastern Europe. TBE can present as meningitis, meningoencephalitis, or meningoencephalomyelitis. Dysfunction of the autonomic (ANS) and peripheral motoric and sensory nervous system (PNS) might contribute to acute and long‐term complications. We aimed to examine, whether the ANS and PNS are affected in acute TBE.MethodsFourteen patients with acute TBE, 17 with diabetic polyneuropathy (d‐PNP), and 30 healthy controls (HC) were examined in our single‐center, prospective study. ANS and PNS function was assessed by time‐ and frequency‐domain parameters of the heart rate (HR) variability at rest and deep respiration, and by sural and tibial nerve neurography. Primary endpoint was the HR variability at rest measured by root mean square of the successive differences (RMSSD). Autonomic symptoms and quality of life (QoL) were assessed by questionnaires.ResultsTick‐borne encephalitis patients had a lower RMSSD at rest (TBE 13.1 ± 7.0, HC 72.7 ± 48.3; P < 0.001) and deep respiration (TBE 42.8 ± 27.0, HC 109.7 ± 68.8; P < 0.01), an increased low‐frequency to high‐frequency power component ratio at rest (TBE 4.0 ± 4.0, HC 0.8 ± 0.5; P < 0.001), and a higher minimal heart rate at rest (TBE 85.4 ± 7.0, HC 69.5 ± 8.5; P < 0.001), all similar to patients with d‐PNP, indicating sympathovagal imbalance with increased sympathetic activation. Compared to HC, sural and tibial nerve conduction velocities and action potential amplitudes were reduced, ANS symptoms were more frequent, and QoL was lower in patients with TBE.ConclusionsThe ANS and to a lesser degree the PNS are affected by acute TBE, which could potentially contribute to short‐ and long‐term morbidity.

ObjectiveTo assess safety and feasibility of autologous adipose‐derived regenerative cells (ADRCs), for treatment of chronic ischemic cardiomyopathy patients.BackgroundPreclinical and early clinical trials suggest ADRCs have excellent potential for ischemic conditions.MethodsThe Athena program consisted of two parallel, prospective, randomized (2:1, active: placebo), double‐blind trials assessing intramyocardial (IM) ADRC delivery [40‐million, n = 28 (ATHENA) and 80‐million (ATHENA II) cells, n = 3]). Patients with an EF ≥20% but ≤45%, multivessel coronary artery disease (CAD) not amenable to revascularization, inducible ischemia, and symptoms of either angina (CCS II–IV) or heart failure (NYHA Class II–III) on maximal medical therapy were enrolled. All patients underwent fat harvest procedure (≤450 mL adipose), on‐site cell processing (Celution® System, Cytori Therapeutics), electromechanical mapping, and IM delivery of ADRCs or placebo.ResultsEnrollment was terminated prematurely due to non‐ADRC‐related adverse events and subsequent prolonged enrollment time. Thirty‐one patients (17‐ADRCs, 14‐placebo) mean age 65 ± 8 years, baseline LVEF(%) 31.1 ± 8.7 (ADRC), 31.8 ± 7.7 (placebo) were enrolled. Change in V02 max favored ADRCs (+45.4 ± 222 vs. −9.5 ± 137 mL/min) but there was no difference in left ventricular function or volumes. At 12‐months, heart failure hospitalizations occurred in 2/17 (11.7%) [ADRC] and 3/14 (21.4%) [placebo]. Differences in NYHA and CCS classes favored ADRCs at 12‐months with significant improvement in MLHFQ (−21.6 + 13.9 vs. −5.5 + 23.8, P = 0.038).ConclusionsA small volume fat harvest, automated local processing, and IM delivery of autologous ADRCs is feasible with suggestion of benefit in “no option” CAD patients. Although the sample size is limited, the findings support feasibility and scalability for treatment of ischemic cardiomyopathy with ADRCs. © 2016 Wiley Periodicals, Inc.
A Visible‐Light‐Triggered Conformational Diastereomer Photoswitch in a Bridged Azobenzene

Published: May 2016

AbstractKetal‐substituted bridged azobenzenes have been synthesized; these display a symmetrical boat conformation with the ketal in pseudo‐equatorial positions. These bridged Z‐azobenzenes (Z1) readily photoisomerize to the E‐isomer as well as another Z‐conformer (Z2) with ketal function on the pseudo‐axial position upon irradiation at 406 nm. The two diastereomeric conformers display distinct physicochemical characteristics. Spectroscopic and NMR investigations supported that interconversion of two conformers occurs via the E‐isomer, with good photochemical quantum yield (Φ
=0.45±0.03, Φ
=0.33±0.05, Φ
=0.37±0.06 and Φ
=0.36±0.04). The system shows high photostability and no thermal equilibrium between the two stable Z1 and Z2 conformers.
