We combine femtosecond polarization resolved VIS-pump IR-probe spectroscopy with DFT and TD-DFT calculations to identify and assign absorption bands to electronic transitions for corroles. These macrocycles and their corresponding metal complexes are receiving great attention because of their utility in many fields, w…
Calcium oxide (CaO) as carbon dioxide (CO2) adsorbent at the elevated temperature has been very well-received thus far. The CaO can be synthesized from natural calcium carbonate (CaCO3) sources through the reversible calcination-carbonation process. In the study, cockle shell has been selected as CaO precursors. The o…
Abstract In this study, the surface of the silica particles was modified with glycidoxypropyl trimethoxysilane and then silica nanoparticle modified alkyd‐melamine resins were synthesized by two methods, namely in situ (IS) polymerization and blending (BL) methods. After alkyd resins containing 40% oil were prepared;…
Two-photon photoemission is used to identify the unoccupied dimer-bond state on the Si(001) surface at an energy 2.83 eV above the valence-band maximum. A strong resonance enhancement is found for excitation from the occupied dangling-bond state. The azimuthal and polarization dependence proves the orientation of the…
Abstract The incorporation of biological function into synthetic polymers provides particular potential for advances in studying the complex interactions between biomolecules and materials. We developed a simple method to create polymer with submicron features on surface of polystyrene‐ co ‐maleic anhydride (PSMAA) us…
ABSTRACT In this work, the water‐in‐oil emulsion solvent diffusion method was developed as an alternative method for preparing cross‐linked silk fibroin (SF) microparticles. Aqueous SF solution and ethyl acetate were used as water and oil phases, respectively. Influence of cross‐linking on morphology and thermal stabi…
Immobilizations of nanoparticles and biomolecules on biocompatible substrates such as titanium are two promising approaches to bringing new functionalities to Ti-based biomaterials. Herein, we used a variety of X-ray spectroscopic techniques to study and better understand metal-thiolate interactions in biofunctionaliz…
Abstract Transparent light‐emitting hybrid materials are produced by UV curing of acrylic resins containing silica precursors and photoluminescent [Cu 4 I 4 L 4 ] clusters. Acrylic double‐bond conversion is followed by means of FT‐IR spectroscopy, and optical measurements are performed on cured films showing a high tr…

A systematic investigation of phase transitions in unmilled and milled LiBH4 has been performed by Pressurized Differential Scanning Calorimetry (PDSC). It was found that a large exotherm is present below the low temperature (LT) → high temperature (HT) phase transition. This exotherm is not caused by air contaminatio…
Selective Oxidation In their contribution on page 118 ff., Gómez, Serp, and co-workers describe efficient catalysts for the selective hydrogenation of cinnamaldehyde to cinnamyl alcohol, the chemical responsible for the hyacinth's scent. Bimetallic platinum/ruthenium nanoparticles stabilized by simple ligands were pre…
We propose a novel, robust, and easily reproducible, in vitro/in silico model system to characterize active and passive stresses in electroactive cardiac muscle using a hybrid experimental/computational approach. We explore active and passive stresses in healthy explanted heart slices in vitro, design a virtual test b…
This paper reports a new electrochemical performance study performed on a planar SOFC cell. This study consists of a 2D model developed using a commercial software, namely Comsol Multiphysics. The model includes fluid dynamics, electrochemistry, electrical conduction, and diffusion physics. This model was built using…
Cadmium sulphide nanoparticles were grown using a wet chemical method, by dissolving the reactants, cadmium chloride and sodium sulphide in water, in the presence of mercaptoethanol (ME), which was used as a capping agent. Manganese chloride was used to dope the nanoparticles. It was found that the particle size varie…
In this study, we synthesized styrene–methyl methacrylate copolymer particles by suspension polymerization process to study the foaming dynamics via visual batch foaming apparatus. The weight ratio of styrene–methyl methacrylate was 53–47. The foaming system consisted of a self-sealing observation cell equipped with t…
Abstract Porous biodegradable poly(ε‐caprolactone) (PCL)/clay nanocomposites were prepared by incorporating a blowing agent into the galleries of an organoclay, followed by mixing the pretreated organoclay and PCL to give partially intercalated and exfoliated nanocomposites and subsequently degrading the blowing agent…
Abstract Asymmetric polysulfone (Psf)/polyvinylpyrrolidone (PVP) hollow fiber membranes were fabricated via dry‐wet spinning process in a custom made apparatus with controlled spinneret and spinning lines temperature. This study investigated the effect of isothermal spinning temperatures on morphology, performance, an…
This paper presents an analysis of advanced cycles with limited CO2 emissions based onthe integration of molten carbonate fuel cells (MCFCs) in natural gas fired combined cycles (NGCC) in order to efficiently capture CO2 from the exhaust of the gas turbine. In the proposed cycles, the gas turbine flue gases are used a…
Abstract By using natural softwood pulp with higher degree of polymerization (DP = 1460) as cellulose source, 1‐butyl‐3‐methylimidazolium chloride ([BMIM]Cl) ionic liquid as solvent and glycerol as plasticizer, a novel cellulose packaging film was prepared. The effects of plasticization conditions on the structures, m…
Abstract The influence of the spherulite size and distribution on the fracture toughness and Izod impact strength at different temperatures of controlled‐rheology polypropylenes with 0, 154, 402, and 546 ppm of peroxide has been evaluated. As the peroxide content increased, the average spherulite size was enhanced and…
