The Elsevier Foundation Green and Sustainable Chemistry Challenge is a collaboration between the Elsevier Foundation and Elsevier's chemistry journals. The five finalists for the 2017 edition pitched their projects during the second Green and Sustainable Chemistry Conference in Berlin, after being selected from nearly 700 submissions by a jury of experts in the field. Proposals addressed challenges in the developing world, focusing on energy, water, waste reduction, agriculture, medicine and more. The 2017 challenge builds off the success of the first year, which drew nearly 500 submissions and awarded innovative projects in biodegradable textile dyeing technology and sustainable agriculture. Dr. Dênis Pires de Lima was awarded the first prize of € 50,000 for his project "From Cashews to castor oil, combating mosquito-borne diseases." Dr. Pires de Lima and his team are using natural waste from locally sourced cashew nuts and castor oil, to produce environmentally friendly insecticides against mosquitoes carrying Zika and Dengue fever - a sustainable alternative to conventional, substantially toxic insecticides. "The problem of diseases carried by mosquitoes is a result of an ecological imbalance in Brazil and many times the best solution will come from nature itself. My prize will provide visibility to a simple and scaleable project which help improve the quality of life for millions of people in Brazil fighting zika," said Dr. Pires de Lima from the Federal University of Mato Grosso do Sul, Brazil. The second prize worth € 25,000 has been awarded to Dr. Chioma Blaise Chikere. Her project "Eco-restoration of crude oil-polluted land in Nigeria" demonstrates how organic nutrients such as garden fertilizers and animal excreta can be used to degrade hydrocarbons, cleaning up the soils heavily contaminated by decades of oil spills. "This award will give me access to better research facilities and help empower local Nigerian women through eco-restauration and biodiversity recovery," said Dr. Chikere. "The winning projects do important work demonstrating how green chemistry solutions can be applied not only in one country and for one specific issue - but can tackle problems across  countries and continents," said Professor Dr. Klaus Kuemmerer from Leuphana University Lueneburg, chair of the challenge's scientific jury. Re-using waste from the cashew nut industry, as in Dr. Pires de Lima's project, is a brilliant example of broad applicability as waste management is an issue in the vast majority of fields. Likewise, Dr. Chikere's proposal shows how local ideas and expertise are needed to find effective solutions - a model that can be embraced by different countries. It's their applicability in different contexts, and their potential to benefit society in its entirety, that makes the two projects so important. They set an example for other developing as well as developed countries on how to approach local problems, and still propose global solutions." Dr. Kuemmerer is also the chair of the Green and Sustainable Chemistry Conference and Editor-in-Chief of Elsevier's journals Current Opinion in Green and Sustainable Chemistry and Sustainable Chemistry and Pharmacy. "The competition shows us how science can serve society by helping to achieve the UN Sustainable Development Goals," said Hannfried von Hindenburg, Senior Vice President of Global Communications at Elsevier. "In working on some of the toughest challenges in their countries, the winners demonstrate that chemistry can be a force for good in the fight against natural or man-made plagues like the Zika virus and environmental oil contamination."

During post preparation, the root canal is exposed to the oral cavity, and endodontic treatment may fail because of coronal leakage, bacterial infection and sealing inability of the luting cement. this study quantified the interfacial continuity produced with conventional dual-cure and self-adhesive resin cements in the cervical (C), medium (M) and apical (A) thirds of the root. Forty single-rooted human teeth were restored using Reforpost # 01 conical glass-fiber posts and different materials (N=10 per group): group AC=Adper™ ScotchBond™ Multi-purpose Plus + AllCem; group ARC=Adper™ ScotchBond™ Multi-purpose Plus + RelyX ARC; group U100=RelyX U100; and group MXC=Maxcem Elite. After being kept in 100% humidity at 37°C for 72 hours, the samples were sectioned parallel to their longitudinal axis and positive epoxy resin replicas were made. The scanning electron micrographs of each third section of the teeth were combined using Image Analyst software and measured with AutoCAD-2002. We obtained percentage values of the interfacial continuity. Interfacial continuity was similar in the apical, medium and cervical thirds of the roots within the groups (Friedman test, p>0.05). Comparison of the different cements in a same root third showed that interfacial continuity was lower in MXC (C=45.5%; M=48.5%; A=47.3%) than in AC (C=85.9%, M=81.8% and A=76.0%), ARC (C=83.8%, M=82.4% and A=75.0%) and U100 (C=84.1%, M=82.4% and A=77.3%) (Kruskal-Wallis test, p<0.05). Allcem, Rely X ARC and U100 provide the best cementation; cementation was similar among root portions; in practical terms, U100 is the best resin because it combines good cementation and easy application and none of the cements provides complete interfacial continuity.

This study investigated the synthesis of graphene oxide nanoribbons (GONRs) and graphene nanoribbons (GNRs) from multiwalled carbon nanotubes (MWCNTs), and the behavior of thin films of MWCNTs, GONRs, and GNRs on a glassy carbon surface in the presence of two redox probes (Fe(CN)6 3-/Fe(CN)6 4- and O2) employing cyclic voltammetry, electrochemical impedance spectroscopy, and hydrodynamic voltammetry (HV) as a simple procedure for characterizing these films. The feasibility of using these electrochemical techniques for this purpose opens up the possibility of applying them to biosensors and electrocatalysts using surface-supported MWCNT, GONR, and GNR materials. GNR1 resembles an internodal segment of bamboo cut lengthwise, with a shallow troughing at its center, while GNR2 resembles stacked ribbons, each ∼16 nm wide, with points of structural damage and points of four-ribbon connection measuring 60 nm or wider, sufficiently catalytic for the oxygen reduction reaction to occur, unlike the other modified electrodes investigated in acidic, 0.1 M KH2PO4 (pH 7.0), and 0.1 M KOH solutions (HV results). Transmission electron microscopy and thermogravimetric analysis were employed to characterize the MWCNTs, GONRs, and GNRs. This journal is © The Royal Society of Chemistry.

This paper presents evaluations among the most usual maximum power point tracking (MPPT) techniques, doing meaningful comparisons with respect to the amount of energy extracted from the photovoltaic (PV) panel [tracking factor (TF)] in relation to the available power, PV voltage ripple, dynamic response, and use of sensors. Using MatLab/Simulink and dSPACE platforms, a digitally controlled boost dc-dc converter was implemented and connected to an Agilent Solar Array E4350B simulator in order to verify the analytical procedures. The main experimental results are presented for conventional MPPT algorithms and improved MPPT algorithms named IC based on proportional-integral (PI) and perturb and observe based on PI. Moreover, the dynamic response and the TF are also evaluated using a user-friendly interface, which is capable of online program power profiles and computes the TF. Finally, a typical daily insulation is used in order to verify the experimental results for the main PV MPPT methods. © 2012 IEEE.

Spinal cord injury is an extremely severe condition with no available effective therapies. We examined the effect of melatonin on traumatic compression of the spinal cord. Sixty male adult Wistar rats were divided into three groups: sham-operated animals and animals with 35 and 50% spinal cord compression with a polycarbonate rod spacer. Each group was divided into two subgroups, each receiving an injection of vehicle or melatonin (2.5 mg/kg, intraperitoneal) 5 min prior to and 1, 2, 3, and 4 h after injury. Functional recovery was monitored weekly by the open-field test, the Basso, Beattie and Bresnahan locomotor scale and the inclined plane test. Histological changes of the spinal cord were examined 35 days after injury. Motor scores were progressively lower as spacer size increased according to the motor scale and inclined plane test evaluation at all times of assessment. The results of the two tests were correlated. The open-field test presented similar results with a less pronounced difference between the 35 and 50% compression groups. The injured groups presented functional recovery that was more evident in the first and second weeks. Animals receiving melatonin treatment presented more pronounced functional recovery than vehicle-treated animals as measured by the motor scale or inclined plane. NADPH-d histochemistry revealed integrity of the spinal cord thoracic segment in sham-operated animals and confirmed the severity of the lesion after spinal cord narrowing. The results obtained after experimental compression of the spinal cord support the hypothesis that melatonin may be considered for use in clinical practice because of its protective effect on the secondary wave of neuronal death following the primary wave after spinal cord injury.

The major contribution of this paper relates to the practical advantages of combining Ground Control Points (GCPs), Ground Control Lines (GCLs) and orbital data to estimate the exterior orientation parameters of images collected by CBERS-2B (China-Brazil Earth Resources Satellite) HRC (High-resolution Camera) and CCD (High-resolution CCD Camera) sensors. Although the CBERS-2B is no longer operational, its images are still being used in Brazil, and the next generations of the CBERS satellite will have sensors with similar technical features, which motivates the study presented in this paper. The mathematical models that relate the object and image spaces are based on collinearity (for points) and coplanarity (for lines) conditions. These models were created in an in-house developed software package called TMS (Triangulation with Multiple Sensors) with multi-feature control (GCPs and GCLs). Experiments on a block of four CBERS-2B HRC images and on one CBERS-2B CCD image were performed using both models. It was observed that the combination of GCPs and GCLs provided better bundle block adjustment results than conventional bundle adjustment using only GCPs. The results also demonstrate the advantages of using primarily orbital data when the number of control entities is reduced. © 2013 International Society for Photogrammetry and Remote Sensing, Inc.

This study reports the use of cyclic voltammetry (CV), hydrodynamic voltammetry, and electrochemical impedance spectroscopy (EIS) to investigate horseradish peroxidase (HRP) direct adsorption onto a glassy carbon (GC) surface and the adsorption of HRP in the presence of polymyxin (PM) forming Nafion®-covered HRP-PM filmsonaGC surface. The bioelectrocatalytic behavior of these electrodes toward H 2 O 2 and O 2 reduction was also studied. The electrochemical reaction rate constant of HRP-PM/Nafion films was comparable to that of bare GC electrodes containing HRP and carbon nanotubes or HRP and graphene in their films. GC/HRP-PM/Nafion electrodes were sufficiently bioelectrocatalytic for H 2O 2 and O 2 reduction (even at pH 7 and 37 °C) - a feature that suggests their possible use as negative electrodes in biofuel cells. From EIS experiments, it was possible to estimate the resistance to electron hopping (R eh) between heme Fe 3+/Fe 2+ redox centers in HRP enzymes and between these and H 2O 2 or O 2 molecules. © 2012 Elsevier Ltd.
