Abstract Triazolindion‐Click‐Chemie und Mikrokontaktchemie wurden kombiniert, um Polymerbürsten auf Oberflächen zu drucken, zu löschen und anschließend erneut anzubinden. Die mikrostrukturierten Polymerbürsten wurden auf Alken‐ und Indol‐Monoschichten gebildet, indem zuerst ein mit Triazolindion (TAD) substituierter A…
This study investigates melt spinnability of ethylene vinyl alcohol (EVOH) copolymers with various ethylene contents, which exhibits excellent biocompatibility but cannot easily undergo single-component fiber spinning. The chemical, thermal and rheological properties of EVOH were examined herein. Three EVOH copolymers…
During a survey of the freshwater littoral diatom flora from lakes and ponds in the region of Petuniabukta on Spitsbergen (Svalbard Archipelago, High Arctic region), a new Achnanthidium species, A. petuniabuktianum sp. nov., has been recorded. Achnanthidium petuniabuktianum is a new representative of the A. pyrenaicum…
Three-dimensional, fibrous scaffolds can be easily fabricated from polylactide (PLA) using melt spinning and textile techniques. However, the surface properties of PLA scaffolds are not ideal for tissue engineering purposes. Furthermore, electrically conducting scaffolds are required to deliver electrical stimulation…
Abstract The preparation, characterization and the molecular structure of a dinuclear uranyl complex [(UO2)2L(OCMe2)2] supported by the bis-salophen ligand N,N′,N″,N′″-tetra-(3,5-di-tert-butylsalicylidene)-1,2,4,5-phenylenetetraamine (L4–) is described. [(UO2)2L(OCMe2)2] was prepared by reaction of uranyl nitrate with…
Quantum systems are inherently dissipation-less, making them excellent candidates even for classical information processing. We propose to use an array of large-spin quantum magnets for realizing a device which has two modes of operation: memory and data-bus. While the weakly interacting low-energy levels are used as…
For organic host-guest systems with a low fraction of guest sites, i.e., the trap-limited case, field-induced detrapping of charge carriers is studied via master equation calculations under the assumption of Miller-Abrahams rates and two Gaussian distributions of uncorrelated energy levels. Among existing descriptions…
In this paper, different MgO films were deposited on a GaAs substrate by atom layer deposition (ALD), which can passivate the surface state of GaAs. From XPS results, the band structure of MgO/GaAs can be indexed to type I. Based on band alignment, the excitons could not diffuse and created nonradiative centers, which…
Although the field of ternary organic solar cells has seen much progress in terms of device performance in the past few years, limited understanding has restricted further development. For example, studies of the crystalline packing structure of ternary blends have rarely been reported in the solar cell field. Consequ…
Abstract. It is demonstrated how a commercially available MEMS thermopile infrared radiation sensor can be used as thermal conductivity gas detector (TCD). Since a TCD requires a heater while IR-thermopile sensors have no integrated heater, the thermopile itself is used as heater and temperature sensor at the same tim…
Abstract Adhesives that selectively debond from a surface by stimuli‐induced head‐to‐tail continuous depolymerization of poly(benzyl ether) macro‐cross‐linkers within a poly(norbornene) matrix are described. Continuous head‐to‐tail depolymerization provides faster rates of response than can be achieved using a small‐m…
We consider the critical system with a point defect and study the variation of thermodynamic quantities, which are the differences between those with and without the defect. Within renormalization group theory, we show generally that the critical exponent of the internal energy variation is the specific heat exponent…
Germanium films were deposited on silicon substrate by an ultra-high vacuum chemical vapor deposition system using GeH4 as Ge precursor and different carrier gases (Ar, N2 and H2). Silicon-germanium and SiGeSn films were deposited using optimized growth conditions of Ge growth. Silane and SnD4 were used as precursors…

It is demonstrated that strong asymmetry in transmission can be obtained at the Gaussian beam illumination for a single prism based on a photonic crystal (PhC) with isotropic-type dispersion, as well as for its analog made of a homogeneous material. Asymmetric transmission can be realized with the aid of refraction at…
α-Crystallin, a member of small heat shock proteins, is the major structural protein within the eye lens and is believed to play an exceptional role in the stability of lens proteins and its transparency. In the current manuscript, we have investigated the effect of an organic solvent, trifluoroethanol (TFE), on the s…
Changes in protein conformation can occur both as part of normal protein functioning and during disease pathogenesis. The most common conformational diseases are amyloidoses. Sometimes the development of a number of diseases which are not traditionally related to amyloidoses is associated with amyloid-like conformatio…
We point out that in the course of application of Ampère's law it is important to fulfil the condition of continuity. We emphasize the role of the displacement current in the case of non-closed circuits. As a didactical example the magnetostatic field generated by the current of a finite-length straight wire is analys…
A rigorous statistical analysis is presented for Gibbs ensemble Monte Carlo simulations. This analysis reduces the uncertainty in the critical point estimate when compared with traditional methods found in the literature. Two different improvements are recommended due to the following results. First, the traditional p…
Novel octylthio-containing asymmetrically substituted Zn(II) phthalocyanine (Zn(II)Pc1) and a symmetric derivative (Zn(II)Pc2) have been prepared to investigate the biological potential and ability to photosensitize singlet oxygen for photodynamic therapy applications. In this study, the singlet oxygen generation pote…
