The effect of surface steps and oxides on the catalytic activity on model Pd and Rh catalysts

En katalysator är en substans som kan snabba på en kemisk reaktion utan attsjälv förbrukas. Katalysatorer används vanligen i kemisk produktion och i bilarsförbränningsmotorer (för att ta bort tex CO och NO). För att optimera katalysatornoch utveckla andra och bättre katalysatorer i framtiden så behöver vi vetahur katalysatorn fungerar på atomär nivå. Katalysatorer i industrin är komplexavilket görA catalyst is a substance that can speed up the rate of a chemical reaction without itself being consumed. Catalysts are crucial for chemical production industries, where about 90% of all chemicals are produced using catalysts. They are also used for exhaust gas cleaning, for instance in cars, where CO and unburned fuels are oxidized to CO2 and NOx is reduced to N2. To optimize catalysts, and deve

Rapidly changing myeloma epidemiology in the general population : Increased incidence, older patients, and longer survival

The incidence of multiple myeloma is characterized by a steep increase with advancing age. Dramatic improvements in survival have been reported in clinical trials; however, elderly patients are generally underrepresented in these. The aims of this study are to review patterns of incidence and survival in multiple myeloma in the general population. We searched PubMed for population-based studies on

Introducing the dilemma of societal alignment for inclusive and responsible research and innovation

In this discussion paper, we outline and reflect on some of the key challenges that influence the development and uptake of more inclusive and responsible forms of research and innovation. Taking these challenges together, we invoke Collingridge’s famous dilemma of social control of technology to introduce a complementary dilemma that of ‘societal alignment’ in the governance of science, technolog

Modelling of methane and hydrogen enriched methane flames in industrial gas turbine burners

The majority of the power production in the world today is based on combustion of coal, oil and natural gas. Most countries have agreed that the amount of CO2 emitted to the atmosphere will have to be decreased to keep the global warming at sustainable levels. One way of reducing the CO2 emitted to the atmosphere is by introducing hydrogen co-firing. The hydrogen may be produced from renewable sou

Toy Consumption as Political : Challenges for Making Dreams Come True

This chapter looks at political consumerism in the toy sector, offering a brief history of consumer concerns and distinguishing among four strands of political consumerist research in this sector. A primary factor facilitating political consumerism of toys is that toy companies are extremely concerned about their reputation. Manufacturers cannot assume that parents and other carers do their usual

Growth kinetics of GaxIn(1−x)P nanowires using triethylgallium as Ga precursor

GaxIn(1−x)P nanowire arrays are promising for various optoelectronic applications with a tunable band-gap over a wide range. In particular, they are well suited as the top cell in tandem junction solar cell devices. So far, most GaxIn(1−x)P nanowires have been synthesized by the use of trimethylgallium (TMGa). However, particle assisted nanowire growth in metal organic vapor phase epitaxy is typic

Reshaping Organic Space by Creative Collective in George Town, Malaysia

In George Town, the capital city of Penang state in Malaysia, Southeast Asia, the creative collectives significantly influence the making of ‘organic space’. This refers to the way in which creative collectives perceive themselves as non-industrialised collaborative groups, employ creativity as the very core of their everyday life, and interact with each other or wider social actors in organic way

Refraining from reporting crimes: accounts from young male crime victims with an immigrant background.

Interactions between the police and young people with an immigrant background are well researched internationally and are often discussed in the context of discrimination. Such interactions may explain, at least in part, why these young people do not report crimes to the police when they are the victims of crimes. This article reports accounts from young crime victims who have an immigrant backgro

Skånes Väl. De skånska regionalisternas möte med de svenska nationalisterna

“Skånes väl”. The scanian regionalists meet the Swedish nationalists. During the past two decades right-wing populist parties have made substantial electoral gains in many West European countries. In Sweden the success of such parties has been limited compared to e.g. Denmark and Norway. In 1998 an electoral coalition of local populist parties, ";Skånes Väl";, in southern Sweden gained 4.1% of the

Socialt kapital och samhällets miniatyrisering

Social capital and the miniaturisation of community. Social capital has been conceptualized both as a contextual property of communities and as a property of individuals. Two of the building blocks of the notion of social capital are social participation and trust. High levels of social participation and trust are reciprocally reinforcing with two-way causality, according to the literature. Howeve

Method for cascading effect analysis in flooding events

A method is presented aiming at enabling more holistic flood risk management efforts by accounting for cascading effects that arise in critical infrastructure and vital societal functions in flooding events. The method is under development but shows promise in guiding national, regional and local risk management efforts in Sweden towards flooding events.
