Nitrogen-Doped Graphene: Efficient Growth, Structure, and Electronic Properties

A novel strategy for efficient growth of nitrogen-doped graphene (N-graphene) on a large scale from s-triazine molecules is presented. The growth process has been unveiled in situ using time-dependent photoemission. It has been established that a postannealing of N-graphene after gold intercalation causes a conversion of the N environment from pyridinic to graphitic, allowing to obtain more than 8

Glycoproteomic identification of galectin-3 and -8 ligands in bronchoalveolar lavage of mild asthmatics and healthy subjects.

BACKGROUND: Galectins, a family of small carbohydrate binding proteins, have been implicated in regulation of inflammatory reactions, including asthma and fibrosis in the lungs. Galectins are found in cells of the airways and in airway secretions, but their glycoprotein ligands there have only been studied to a very limited extent. METHODS: Bronchoalveolar lavage (BAL) fluid from mild asthmatics a

Photophysics of an Intramolecular Hydrogen-Evolving Ru-Pd Photocatalyst

Photoinduced electron-transfer processes within a precatalyst for intramolecular hydrogen evolution [(tbbpy)(2)Ru(tpphz)PdCl2](2+) (RuPd; tbbpy = 4,4'-di-tert-butyl-2,2'-bipyridine, tpphz = tetrapyrido[3,2-a:2',3'c:3 '',2 '',-h:2"',3'''-j]phenazine) have been studied by resonance Raman and ultrafast time-resolved absorption spectroscopy. By comparing the photophysics of the [(tbbpy)(2)Ru(tpphz)](2

Constructions of Deportability in Sweden. Refused Asylum Seekers’ Experiences in Relation to Gender, Family Life, and Reproduction

Drawing on ethnographic material, this article examines how the experiences of refused asylum seekers in Sweden are shaped by migration policies, welfare policies, and gender norms. The article develops a feminist account of deportability to examine some gendered and reproductive aspects of everyday experiences of seeking asylum in Sweden. Focusing on the interview accounts of one heterosexual cou

Tibiofemoral Joint Osteoarthritis: Risk Factors for MR-depicted Fast Cartilage Loss over a 30-month Period in the Multicenter Osteoarthritis Study

Purpose: To assess baseline factors that may predict fast tibiofemoral cartilage loss over a 30-month period. Materials and Methods: The Multicenter Osteoarthritis (MOST) study is a longitudinal study of individuals who have or who are at high risk for knee osteoarthritis. The HIPAA-compliant protocol was approved by the institutional review boards of all participating centers, and written informe

Visual observations and acoustic measurements of cavitation in an experimental model of a high-pressure homogenizer

Cavitation is common in high-pressure homogenizers, and has severe negative effects such as noise and mechanical wear, but may also have a beneficial effect in promoting fragmentation. Greater knowledge concerning cavitation in the homogenizer valve is thus important in optimizing the design and utilization of emulsification equipment. The aim of this study was to locate the region of cavitation a

Patterns of background factors related to early RA patients' conceptions of the cause of their disease

The aim of the present study was to identify patterns of background factors related to the early RA patients' conceptions of the cause of the disease. Conceptions from a qualitative study formed the basis for the stratification of 785 patients from the Swedish EIRA study answering a question about their own thoughts about the cause to RA. Logistic regression analyses were used to explore the assoc

Simultaneous saccharification and cofermentation of lignocellulosic residues from commercial furfural production and corn kernels using different nutrient media

Abstract Background: As the supply of starch grain and sugar cane, currently the main feedstocks for bioethanol production, become limited, lignocelluloses will be sought as alternative materials for bioethanol production. Production of cellulosic ethanol is still cost-inefficient because of the low final ethanol concentration and the addition of nutrients. We report the use of simultaneous saccha

Geographic and molecular variation in a natural plant transgene.

A PCR based survey of Festuca ovina plants from populations around the southern part of the Baltic Sea demonstrates both geographic and molecular variation in the enzyme gene PgiC2, horizontally transferred from a Poa-species. Our results show that PgiC2-a natural functional nuclear transgene-is not a local ephemeral phenomenon but is present in a very large number of individuals. We find also tha

Search for top and bottom squarks from gluino pair production in final states with missing transverse energy and at least three b-jets with the ATLAS detector

This letter reports the results of a search for top and bottom squarks from gluino pair production in 4.7 fb(-1) of pp collisions at root s = 7 TeV using the ATLAS detector at the LHC. The search is performed in events with large missing transverse momentum and at least three jets identified as originating from a b-quark. Exclusion limits are presented for a variety of gluino-mediated models with

Phase diagrams come alive: understanding how to create, destroy or change ordered surfactant structures by polymerizing the counterions

Free radical polymerization of acrylate counterions to cationic alkyltrimethylammonium surfactant ions was performed in aqueous media. The results of the reactions were either formation, destruction or change of liquid crystalline surfactant structures, depending on the starting conditions such as the surfactant concentration, the content of inert counterions and the monomer-to-initiator ratio. Th

Constructing Regional Advantage: Platform Policies Based on Related Variety and Differentiated Knowledge Bases

ASHEIM B. T., BOSCHMA R. and COOKE P. Constructing regional advantage: platform policies based on related variety and differentiated knowledge bases, Regional Studies. This paper presents a regional innovation policy model based on the idea of constructing regional advantage. This policy model brings together concepts like related variety, knowledge bases and policy platforms. Related variety atta

Investigations of film cooling and its nonuniform distribution for the conjugate heat transfer passage with a compound inclined angle jet

Film cooling effectiveness and its distribution characteristics on the gas turbine blade surface were investigated numerically. Seven rectangular ribs were located on the internal wall, and a film cooling hole had a compound inclined angle. The case with a compound angle of 45 degrees was designed to improve the lateral film cooling effectiveness on the downstream surface. The secondary flow jet f

On the importance of life history and age structure in biological invasions

The age specific patterns of reproduction and mortality dictated by the life history of an organism apply to potential invaders as well as resident species of an area, but whether certain life history traits are more invasive than others is an unresolved issue. We analyze a two-population system of an invading and a resident species and test the effects of age on the probability to invade when the

Overextension in Verb Conjunctions

Hampton (1988) discovered that people are subject to overextension they categorize some things as falling under a conjunction (e.g., they categorize chess as a sport which is also a game) but not as falling under both of the corresponding conjuncts they do not categorize chess as a sport). Although subsequent literature has replicated this effect with a wider range of constructions than those orig

Abstract in French L'auteur suggére une série d'études comparatives qui traitent de la perception des pirogues à balancier, et qui visent à mieux cerner les rapports existant entre les relations sociales, la biodiversité et le développement durable dans les sociétés océaniennes des petites îles et des zones côtières exposées à de rapides mutations culturelles. Après avoir critique l'idée récente s

Influence of Different Rim Widths and Blowing Ratios on Film Cooling Characteristics for a Blade Tip

Three-dimensional simulations of the squealer tip on the GE-E-3 blade with eight film cooling holes were carried out. The effect of the rim width and the blowing ratio on the blade tip flow and cooling performance were revealed. Numerical simulations were performed to predict the leakage flow and the tip heat transfer with the k-epsilon model. For the squealer tip, the depth of the cavity is fixed
