Correlation between Soft X-ray Absorption and Emission Spectra of the Nitrogen Atoms within Imidazolium-Based Ionic Liquids

Soft X-ray absorption spectroscopy (XAS) has been performed on the N K-edge of two imidazolium-based ionic liquids (ILs), 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide ([C 2 mim][TFSA]) and 1-ethyl-3-methylimidazolium bromide ([C 2 mim][Br]), to clarify the electronic structures of the ILs. Soft X-ray emission spectroscopy (XES) has also been applied to the ILs by excitation at va

Growth of a Long Bone Cross Section - A 2D Phase-Field Model

An approach to model the effect of exercise on the growth of mammal long bones is described. A Ginzburg-Landau partial differential equation system is utilised to study the change of size and shape of a cross-section caused by mechanically enhanced bone growth. The concept is based on a phase variable that keeps track of the material properties during the evolution of the bone. The relevant free e

Identification of of elastic/visco-plastic material constants under impact loading

A method for identifying the material constants of an elastic/visco-plastic meterial under tensile impact loading is proposed. In this method, the Kalman filter and the finite element method are used together with a few test data. To obtain data for high strain rates, notched specimens are employed, because arbitrarily shaped specimens are available in this method. To increase the accuracy of iden

High resolution X-ray emission spectroscopy of water and its assignment based on two structural motifs

We evaluate proposed interpretations of previous X-ray emission spectroscopy (XES) data on liquid water. The split peak in the lone-pair orbital region has been interpreted in terms of either two different structural motifs, tetrahedral and distorted, or as due to core-hole-induced dissociative dynamics; here we add new data on a 1:1 H2O/D2O isotopic mixture and additional spectrum simulations inc

High resolution X-ray emission spectroscopy of liquid water : The observation of two structural motifs

The structure of liquid water is presently under intense debate. We summarize the historical development of the present description of water and the controversy surrounding the X-ray absorption spectroscopy (XAS) study of Wernet et al. [Ph. Wernet et al., Science 304 (2004) 995]. In order to provide further insight into the connection between X-ray spectroscopy and the structure of the hydrogen bo

Transnational and Local Memories of World War I in Sweden : the Case of Bohuslän

After the WWI Battle of Jutland in 1916, hundreds of dead British and German marines drifted ashore on the beaches of the region of Bohuslän in western Sweden. They were buried in local cemeteries, until the remains of most of the soldiers were reburied in Gothenburg in the 1960s. The chapter focuses on two local Bohuslän memory cultures in relation to the sailors and their graves. It seeks to ide

SEVEN (Supercompact Electric Vehicle National) is a research project of Universidad Nacional de Colombia. The main goal is to design a electric "concept car" for shared use. The SEVEN vehicle is designed with characteristics of the industry 4.0: autonomous vehicle level III, interconnected (IoT) and can be manufactured flexibly, on demand by rapid manufacturing of 3D printing.
