Self-assembly has surfaced as a promising way of fabrication of novel hybrid materials and nanostructures. The work offered in this dissertation has been centered on creating nanoscale materials based on synthetic de novo designed polypeptides. The polypeptides have been useful for the
There are many different codes available for making molecular dynamic simulation. Most of these are focused on high performance mainly. We have moved that focus towards modularity, flexibility and user friendliness. Our goal has been to design a software that is easy to use, can handle many different kind of simulations and is easily extendable to meet new requirements.
In every living cell, millions of different types of molecules constantly interact and react chemically in a complex system that can adapt to fluctuating environments and extreme conditions, living to survive and reproduce itself. The information required to produce these components is stored in the genome, which is copied in each cell division and transferred and mixed with another genome from parent to child.
One dimensional silicon nanomaterials has become more and more popular for optoelectronic, chemical and bio-chemical devices due to their semi-conducting ability and convenience for chemical modification by different chemical species. In order to achieve these purposes, many efforts have been input to the synthesis of silicon nanowires (SiNWs).
Glutathione S-transferases (GSTs) are an important family of xenobiotic biotransforming enzymes that can make toxicity tests variable. Daphnia magna is commonly used in ecotoxicology testing because they are easy to culture, have a short life cycle, and reproduce by parthenogenesis.
Apatites are a diverse class of phosphate minerals that are important in a great variety of natural and industrial processes. They are, for example, used as raw material in fertiliser production and in the remediation of metal-contaminated soils. Hydroxyapatite Ca5(PO4)3OH, (HAP) and fluorapatite Ca5(PO4)3F, (FAP) are similar to the biological apatite that is the main constituent of mammalian bone and teeth, and they are therefore promising materials for artificial bone and tooth implants.
This thesis describes the application of multivariate methods in a novel approach to the formulation of tablets for direct compression. It begins with a brief historical review, followed by a basic introduction to key aspects of tablet formulation and multivariate data analysis.
Plant-feeding insects account for about one fourth of macroscopic biodiversity. This study aims to document factors contributing to this diversity by investigating phylogenetic relationships within a large radiation of herbivorous insects, Phytomyza leaf-mining flies Diptera: Agromyzidae. A handful of prominent results include 1) host use conservatism at the family level predominates, with shifts occurring at about 5% of speciation events
This thesis concerns quadratic response properties and their application to properties in Jablonski diagrams such as resonant two-photon absorption and excited state absorption. Our main interest lies in optical power limiting applications, and in this context, molecules containing heavy metal atoms prove superior.
The Holocene spread of Picea abies in Scandinavia provides an excellent opportunity for detailed study of the dynamics of tree spread and population expansion. Early- and mid-Holocene macrofossil evidence for the presence of Picea abies in Scandinavia has questioned traditional interpretations of the timing and direction of its spread.
