    Description: Poly (2,5-benzimidazole) (ABPBI) and zirconium oxide (ZrO ) nanoparticles composite membranes were synthesized. These membranes can be fabricated into tough, dense membranes by blending Poly (2,5-benzimidazole) (ABPBI) with zirconium oxide (ZrO ) nanoparticles, which were characterized by using FTIR, XRD, SEM, TGA, DSC and tensile test. These composite membranes showed increased conductivity compared with original ABPBI membrane. Maximum proton conductivity at 100 °C was found to be 0.069 S cm on 10% ZrO incorporated ABPBI composite membrane, almost four times as high as the 0.018 S cm obtained in the case of the ABPBI membrane. The conductivity was 0.0325 S cm at 180 °C in dry condition for ABPBI with 10% ZrO nanoparticles composite membrane, higher than the conductivity 0.011 S cm of the ABPBI membrane at same condition. Furthermore, the composite membranes were shown to have high thermal and mechanical stability. These results suggest that ABPBI/ZrO composite membranes may be a promising polymer electrolyte for fuel cells at medium or high temperature, due to their strong physical properties.

    Description: Single crystal tungsten oxide (WO ) nanoparticles were prepared via a microwave-assisted method. Electrochemical activity for hydrogen evolution reaction (HER) on WO supported on carbon black (WO /C) electrocatalyst was first studied in acid solution (0.5 M H SO ) and alkaline solution (1.0 M KOH) at room temperature. The overall experimental results revealed that the electrocatalytic activity for HER on WO /C is one order magnitude higher than those obtained with carbon black in 0.5 M H SO and is six times than in the case of carbon black in 1.0 M KOH. These results demonstrated that WO could enhance the electrocatalytic activity for hydrogen evolution reaction in acid solution (0.5 M H SO ) and alkaline solution (1.0 M KOH). On the other hand, the kinetic reaction mechanisms were discussed on WO /C electrocatalysts and carbon black in acid solution and alkaline solution for HER. Consequently, the rate-determining step changed from Tafel to Volmer due to the incorporation of WO in acid solution. However, the rate-determining step carries through Tafel reaction on both electrocatalysts in alkaline solution though WO was introduced.

    Description: The authors proposed and tested a model in which data were collected from managers ( n = 539) at 116 corporate-owned quick service restaurants to assess the structural and psychological empowerment process as moderated by shared-felt accountability on indices of performance from a managerial perspective. The authors found that empowering leadership climate positively relates to psychological empowerment climate. In turn, psychological empowerment climate relates to performance only under conditions of high-felt accountability; it does not relate to performance under conditions of low-felt accountability. Overall, the present results indicate that the quick-service restaurant managers, who feel more empowered, operate restaurants that perform better than managers who feel less empowered, but only when those empowered managers also feel a high sense of accountability.

Direct coupling of the heterocyclic base involved a Mitsunobu reaction as key step. The compounds were evaluated for their antiviral properties, but none of them showed significant activity.

Whitaker (1,*), M. Mathe (2) Despite recent advances precision diagnostic criteria on how best to diagnose and treat EUPD remains debated. Therapeutic indication and appropriate use of anti-psychotics including clozapine in this patient group remains unclear. It is debated about personality disorder being diagnosed in children and adolescents, overall it is much more acceptable for adolescents to be given a diagnosis of 'emerging' personality disorder if they exhibit clinical features of such. Clozapine has been used (as an off-license treatment) in adults diagnosed with personality disorder improving psychopathology and quality of life. These patients have been tried on numerous other treatments. In a secure unit for adolescent girls who meet the criteria for a diagnosis of emergent personality disorder who posed serious risks to themselves and others three were given a trial of clozapine The off license use of clozapine was tried in all three patients showed a reduction in incidents, reduced need for polypharmacy and improvement in their qualities of life. One cannot account for these changes being the result of clozapine alone; however, these cases add to the growing body of evidence of the benefits of clozapine in patients with emergent personality disorder.

    Description: During development, the formation of biological networks (such as organs and neuronal networks) is controlled by multicellular transportation phenomena based on cell migration. In multi-cellular systems, cellular locomotion is restricted by physical interactions with other cells in a crowded space, similar to passengers pushing others out of their way on a packed train. The motion of individual cells is intrinsically stochastic and may be viewed as a type of random walk. However, this walk takes place in a noisy environment because the cell interacts with its randomly moving neighbors. Despite this randomness and complexity, development is highly orchestrated and precisely regulated, following genetic (and even epigenetic) blueprints. Although individual cell migration has long been studied, the manner in which stochasticity affects multi-cellular transportation within the precisely controlled process of development remains largely unknown. To explore the general principles underlying multicellular migration, we focus on the migration of neural crest cells, which migrate collectively and form streams. We introduce a mechanical model of multi-cellular migration. Simulations based on the model show that the migration mode depends on the relative strengths of the noise from migratory and non-migratory cells. Strong noise from migratory cells and weak noise from surrounding cells causes “collective migration,” whereas strong noise from non-migratory cells causes “dispersive migration.” Moreover, our theoretical analyses reveal that migratory cells attract each other over long distances, even without direct mechanical contacts. This effective interaction depends on the stochasticity of the migratory and non-migratory cells. On the basis of these findings, we propose that stochastic behavior at the single-cell level works effectively and precisely to achieve collective migration in multi-cellular systems.

    Description: The proton exchange membrane based on polyetheretherketone was prepared via two steps of cross-linking. The properties of the double cross-linked membrane (water uptake, proton conductivity, methanol permeability and thermal stability) have been investigated for fuel cell applications. The prepared membrane exhibited relatively high proton conductivity, 3.2 × 10  S cm at room temperature and 5.8 × 10  S cm at 80 °C. The second cross-linking significantly decreased the water uptake of the membrane. The performance of direct methanol fuel cell was slightly improved as compared to Nafion 117 due to its low methanol permeability. The results indicated that the double cross-linked membrane is a promising candidate for the polymer electrolyte membrane fuel cell, especially for the direct methanol fuel cell due to its low methanol permeability and high stability in a methanol solution. ► The proton exchange membrane was prepared via two steps of crosslink. ► The membrane exhibited relatively high proton conductivity compared to Nafion. ► The second crosslink reduced the water uptake and methanol cross-over. ► The preparation of the membrane did not involve the use of expensive materials. ► Good performance of direct methanol fuel cell was carried out in this work.
