The technique of molecular imprinting : Principle, state of the art, and future aspects

Molecular imprinting has gained increasing research interest during the past few years. In this overview we would like to explain to the readers how a seemingly simple concept can eventually lead to useful applications in several areas. The main focus will be on the present state of the art of molecular imprinting, as several breakthroughs have occurred since most reviews by us and other groups ha

A new approach to materials in Product Design education : A shift from technical properties towards sensorial characteristics

This study evaluates a new pedagogic approach implemented in material courses for product design students at bachelor level education. Material education within the field of design education at technical faculties has, in general, a strong technical focus, e.g. selecting materials with predominant focus on engineering properties of materials. Product design education at a bachelor level need to of

Single-step partitioning in aqueous two-phase systems

Partitioning in aqueous two-phase system (ATPS) provides a rapid and gentle means of separation of soluble as well as particulate biomaterials, e.g. proteins, nucleic acids, cells, viruses, organelles, and membranes. Partitioning between the two phases is a complex phenomenon, guided mainly by the interaction of the partitioned substance and the phase components, e.g., through hydrogen bonds, van

Disparities in mobility among older people : Findings from a capability-based travel survey

Despite some incremental policy shifts accounting for transport equity concerns, the norms within which transport systems worldwide currently function are still implicitly exclusive. Older people constitute a group which is particularly susceptible to issues within the transport system. However, this susceptibility is not evenly distributed, partly due to the considerable heterogeneity in circumst

Using HEC-HMS and HEC-RAS Models for Rainfall-Runoff Simulation and Flood Inundation Mapping: Case Studies from Nepal and Sweden

Understanding catchment behaviour through rainfall-runoff models allows decision makers for proper planning and operation in context of flood risk management. However accurate rainfall-runoff and flood modelling at high spatio-temporal resolutions still remains a significant challenge in any hydrologic and hydraulic studies. This study seeks to develop Hydrologic Engineering Centre’s Hydrologic Mo

Körsång påverkar : Forskare berättar

Under Föreningen Sveriges Körledares konvent i Jönköping oktober 2009 debatterades musikens och särskilt sångens ställning i skolan. I debatten framkom en stark oro för sångens framtid bland barn och unga. Körledaren behöver öka sin kunskap för att kunna argumentera bättre för sång och körsång som en grundläggande erfarenhet och rättighet, menade man. Ofta tvingas körledaren själv förklara för bes

Future contingents, Supervaluationism, and relative truth

The problem of future contingents is one of the most ancient and debated puzzles in Western philosophy, and Supervaluationism is, today, one of the most prominent solutions to the problem. Recently, John MacFarlane has carried a well-known criticism to Supervaluationism (and all other standard approaches to future contingents) and put forward a new solution of the problem of future contingents, wh

Structure and high photocatalytic activity of (N, Ta)-doped TiO2 nanoparticles

A hydrothermal method was used to prepare three nano-crystalline samples of TiO2 (S1), N-doped TiO2 (S2), and (N, Ta)-codoped TiO2 (S3) with average crystallite sizes (D) of 13-25 nm. X-ray diffraction studies confirmed a single phase of the samples with a tetragonal/anatase structure. A slight increase in the lattice parameters was observed when N and/or Ta dopants were doped into the TiO2 host l

X-ray absorption spectroscopy of ground and excited rhenium-carbonyl- diimine complexes : Evidence for a two-center electron transfer

Steady-state and picosecond time-resolved X-ray absorption spectroscopy is used to study the ground and lowest triplet states of [ReX(CO) 3 (bpy)] n+ , X = Etpy (n = 1), Cl, or Br (n = 0). We demonstrate that the transient spectra at both the Re L 3 -and Br K-edges show the emergence of a pre-edge feature, absent in the ground-state spectrum, which is associated with the electron hole created in

Time-resolved X-Ray emission spectroscopy

We present ultrafast x-ray emission studies of photoexcited aqueous iron tris-bipyridine with 70 ps temporal resolution to monitor the spin state changes in this spin-crossover complex.

EXAFS structural determination of the Pt2(P2O 5H2)44- anion in solution

We present the first structural determination of the Pt2(P 2O5H2)44- anion in solution by analyzing the extended X-ray absorption fine structure (EXAFS) spectrum of the Pt LIII edge. The data could be fit with a simple model involving single and multiple scattering paths to near and far P-atoms, bridging O-atoms, and the other Pt-atom in the binuclear complex. A Pt-Pt distance of 2.876(28) Å and a

Cytokine Autoantibody Screening in the Swedish Addison Registry Identifies Patients With Undiagnosed APS1

Context: Autoimmune polyendocrine syndrome type 1 (APS1) is a monogenic disorder that features autoimmune Addison disease as a major component. Although APS1 accounts for only a small fraction of all patients with Addison disease, early identification of these individuals is vital to prevent the potentially lethal complications of APS1.Objective: To determine whether available serological and gene
