Indium arsenide nanowires are grown directly on silicon substrates (see figure and cover) using a method employing self-assembled organic coatings to create oxide-based growth templates. High-performance materials, such as InAs, could have great impact on future nanoelectronics if integrated with Si, but integration has so far been hard to realize with other methods.
The production of methane via anaerobic digestion of agricultural residues and industrial wastewater would benefit society by providing a clean fuel from renewable feedstocks. This would reduce the use of fossil-fuel-derived energy and reduce environmental impact, including global warming and pollution. Limitation of carbon dioxide and other emissions through emission regulations, carbon taxes, an
After the storm. A sociological analysis of families owning forest properties. A Book By Sellerberg publiched by Bokbox, March 2011 "Has it been windy?", someone asks a forest owner in March 2005. In January practically all of his forest was annihilated. A storm rolled by with winds as strong as 46 metres per second. The forest owners in Kronoberg county were particularly badly hit by the disaste
To be successful in Information Systems (IS) outsourcing the necessity of better management practices has been pointed out.This research contributes to the knowledge base on management of IS outsourcing by addressing management of ISoutsourcing relationships. The research describes two cases of IS outsourcing relationships that differ in type of activityoutsourced, IS development versus IS mainten
The perspective of the public sphere, despite its utility, has some gaps. Not least is its lack of sociological anchoring in the everyday lives and experiences of citizens. The text argues that we can illuminate the media's role in promoting or hindering participation in the public sphere by making use of the six-dimensional framework of civic cultures.
Popular Abstract in Swedish För drygt tio år sedan startade ett forskningsprojekt mellan fyra avdelningar på Kemicentrum i Lund i syfte att ta fram en process för framställning av etanol ur snabbväxande energiskog. Etanol är ett miljövänligt alternativ till bensin som drivmedel för bilar och bussar, och redan idag körs ungefär 100 bussar i svenska städer på detta bränsle. Priset på drivmedelsetanoSystems for on-line monitoring of bioprocesses were developed, consisting of a membrane-based sampling unit, a liquid chromatographic (LC) separation step, and a detector. Two sampling units, a tangential flow filtration (TFF) module and a microdialysis probe, were characterised and evaluated for use in different types of bioprocesses. When using the TFF module, an additional sample clean-up step
The spectrum efficiency in a cellular radio system is affected by the data rates used in the system. High data rates may result in low spectrum efficiency if the frequency reuse is low. The spectrum efficiency may be enhanced by using adaptive modulation with carefully chosen data rates. We present an analytical method, based on a lower bound on the BER, for finding the best data rates. The method
