The long term objectives of this research are to develop regenerative, sorption-reinforced catalytic substrates capable of detecting and decomposing a range of warfare chemicals including organophosphorus (OP) nerve agents and sulfur mustard compounds. Our approach consists of embedding a biocatalytic composite into t…
This chapter provides an overview of the application of synthetic polymeric biomaterials in musculoskeletal regenerative and reconstructive medicine with selected examples. Hydrogels capable of cell and growth factor delivery were assessed for injectable cartilage tissue engineering. Injectable composite scaffolds inc…
CrO2 is a ferromagnetic half metal with 100% polarization of conduction electrons, and BaTiO3 has been known as to be ferroelectric at room temperature. We prepared the multi-ferroic granular junctions from the mixture of CrO2 and BaTiO3. If the BaTiO3 forms a good tunneling barrier for conduction electrons, the enhan…
The present study was aimed to evaluate the effect of Portulaca oleracea L on fertility of female albino rats. Albino rats were orally administered with Petroleum Ether, chloroform and Ethanol crude extracts of aerial part of Portulaca oleracea L in both high and low dose (500mg and 250 mg / kg of body weight / day, f…
In order to obtain stable biphasic solvent mixtures such as emulsions and miniemulsions, distinct emulsifiers are required for the liquid/liquid interface. Until recently, nanoscale polymer particles have been mainly gained from waterborne heterophase techniques in radical processes, herein nonaqueous emulsions are pr…
Bio-inspired adhesive vesicles are designed by self-assembly of di-acetylenic fatty acids that were modified at the carboxylic acid head-group with either cell-adhesive or mussel-adhesive peptide sequences. The amphiphiles are stabilised by UV-light induced polymerisation of the hydrophobic tail into well-defined stru…
Large-pore organosilicas with methylene and ethylene bridges in the framework were synthesized at low initial temperature (15 °C) using hexane as a swelling agent and Pluronic P123 (EO 20 PO 70 EO 20 ) block copolymers as template. Organosilica materials with the nominal (KJS) pore sizes of 18 and 10 nm were obtained…
Japan is extremely poor in natural resources, relying on imports for approximately 80 per cent of its primary energy requirements. In particular, nearly 90 per cent of its crude oil is supplied from the Middle East. Since the oil crises of 1973 and 1979, Japan has diversified its energy sources by introducing nuclear…
Metal hydride materials can store a huge amount of hydrogen and can convert energy due to enthalpy change through a hydride reaction. Artificial actuation systems that employ this special physicochemical property are named metal hydride actuators. The actuators utilize the mechanical energy formed from hydrogen equili…
The contribution is focused on the recent experience of X-ray Diffraction Laboratory of the Czech Technical University in Prague and Department of Machining and Assembly of the Technical University of Liberec with industrial applications of X-ray diffraction residual stress measurement and Barkhausen noise analysis. B…
Small photochromic molecules are widespread in nature and serve as switches for a plethora of light-controlled processes. In a typical photoreceptor, the different geometries and polarities of the photochrome isomers are tightly coupled to functionally relevant conformational changes in the proteins. The past decade h…
In this study, fermentation broth pervaporation is compared to ethanol/water pervaporation. Laboratory unfilled en ZSM-5 filled PDMS membrane samples were used for this purpose. No significant changes were observed for the unfilled membrane, whereas water flux of the zeolite filled membrane was higher during fermentat…
Amyloid β-peptide (Aβ) is a major component of plaques in Alzheimer’s disease, and formation of senile plaques has been suggested to originate from regions of neuronal membrane rich in gangliosides. We have analyzed the interaction of Aβ with lipid bilayers by multinuclear NMR using 15 N, 31 P and 13 C nuclei. The res…
In textile production, the yarn is being withdrawn from cross-wound packages in warping and weft insertion. During unwinding, there appear forces in the yarn which are approximately proportional to the square of the unwinding velocity. The production process requires as large warping and weaving speeds as possible, th…
Dynamic Contrast Enhanced imaging (DCE-imaging) following a contrast agent bolus allows the extraction of information on tissue micro-vascularization. The dynamic signals obtained from DCE-imaging are modeled by pharmacokinetic compartmental models which integrate the Arterial Input Function. These models use ordinary…
Glass Structure / Solid State NMR Spectroscopy / Structure-Property Relations Glassy ionic conductors have attained considerable importance in the solid state battery technology field. To understand the influence of composition on ionic mobility and transport, information about the local and dynamic environments of th…
Nanoparticles (NPs) and molecular surfactants are two classes of compounds which spontaneously localize at oil/water interfaces. Industrial and commercial applications of these systems often require precise two-dimensional organization of the localized NPs. An impediment to the realization of such systems is our under…
The reaction of Dy(NO(3))(3)center dot 6H(2)O with the ligand 2-((1-hydroxybutan-2-ylimino)methyl) phenol (H(2)L, Scheme 1) generates the nonanuclear compound [Dy(9)L(8)(mu(3)-OH)(8)(mu(4)-OH)(2)(CH(3)OH)(8)](OH)(CH(3)OH)(3) (Dy(9)), whose single-crystal X-ray structure reveals the presence of two square pyramidal pen…
Fiber spinning processes are used to manufacture hollow fibers for the membrane industry. Ideally, the spinning process produces fiber of controlled size and morphology. Theoretical models of the process provide tools for evaluating the dependence of fiber properties on process variables and thereby facilitate process…
Dye sensitized solar cells (DSCs) are promising alternative to conventional Si-based solar cells due to their low cost, easy fabrication and relatively high conversion efficiency. In the DSC, the electrolyte plays an important role in the regeneration of dye molecules and the charge transportation. Although the DSCs b…
