Selective Catalytic Reduction (SCR) is a promising technique in mitigating the drawbacks of combustion system. This study investigated the potential of using coconut shell activated carbon (CSAC), an abundant and inexpensive resource, as an SCR catalyst support for sustainable energy generation. Local CSAC was physica…
The inaugural SANZMAG conference was held at the University of Sydney from 17 to 20 February 2014, and was aimed at drawing together local researchers interested in molecular magnetism in an informal workshop-style environment. This meeting was specifically aimed at researchers of honours to postdoctorate level, with…
Dieses Kapitel beschreibt die moderne Rasterelektronenmikroskopie, die sich zu einem leistungsstarken Werkzeug insbesondere für die Untersuchungen sowohl von lokalen Gitterdefekten als auch von Verformungs- und Schädigungsmechanismen in verschiedenen Werkstoffen entwickelt hat. Auf dem Gebiet der Werkstofftechnik sind…
This chapter provides an overview of some basic solid materials which exhibit the photocatalytic activity necessary for conversion of CO2 in the presence of H2. It introduces the interaction between adsorbent and adsorbate for photocatalytic conversion of CO2. The determining factor for the photocatalytic conversion o…
An X-ray absorption spectroscopy (XAS) experiment is usually carried out through recording the absorption signal as a function of photon energy. An XAS spectrum can be divided into two regions: the X-ray absorption near-edge structure (XANES) and the extended X-ray absorption fine structure (EXAFS). Soft XAS (SXAS) en…
We have studied the temperature evolution of the inverse photoemission spectra of phase separated La$_{0.2}$Sr$_{0.8}$MnO$_{3}$. To identify the features in the room temperature experimental spectra, band structure calculations using Korringa-Kohn-Rostoker Green's function method were carried out. We find that the fea…

A surface reaction mechanism consists of several elementary steps including adsorption and desorption of reactants, products, and intermediates, surface diffusion of adsorbates, and bond-breaking/bond-making steps that generate new reactive intermediates. Microkinetic modeling, presented in this chapter, aims at under…
The research aims to assess the environmental condition of the Kampar River waters based on the species and abundance of epiphytic diatoms, to know the species of epiphytic diatoms seen from water quality condition of Kampar River water sand to determine the dominant species of epiphytic diatoms. The research was cond…
Dielectric materials with tunable permittivity are highly desirable for wireless communication, radar technology. However, the tunability of dielectric properties in the microwave frequency range and higher is an immense challenge for conventional materials. Here, we demonstrate a giant magnetodielectric effect in the…
Les structures sandwich sont des structures légères composées de deux peaux superficielles minces, relativement denses, à haute résistance qui sont collées de part et d'autre d'une âme, épaisse, de faible densité telle que les mousses ou nids d'abeilles. Les matériaux sandwich à peau composite renforcée de fibres plas…
This note relies heavily on arXiv:1404.6509 and arXiv:1410.7693. Both articles discuss domino tilings of three-dimensional regions, and both are concerned with flips, the local move performed by removing two parallel dominoes and placing them back in the only other possible position. In the second article, an integer…
La therapie photodynamique (PDT) est utilisee actuellement pour traiter certains cancers accessibles par irradiation laser. Son principe repose sur l'action combinee de la lumiere et d'un principe actif nomme photosensibilisant (PS). La molecule photosensible genere des especes reactives de l'oxygene sous l'action d'u…
This thesis focus on the development of two differentiated devices, using common and interchangeable materials: (1) electronic diodes and (2) electrochemical capacitors, also known as supercapacitors. Special attention was given for these devices to be transparent or at least translucent. This work is proposed as a fi…
We present the results of XPS measurements (core levels and valence bands) of solution processed TiOx thin films prepared from titanium butoxide (C16H36O4Ti) diluted in isopropanol which is a common sol-gel route for fabricating TiOx electron selective contacts for ITO/TiOx inverted organic photovoltaics bottom electr…
Die Auslegung von Bauteilen wird stets für einen bestimmten Temperaturbereich vorgenommen. Daher erfolgt die Ermittlung der Wechselfestigkeit von Werkstoffen meist für eine isotherme Beanspruchung bei entsprechender Einsatztemperatur. Thermomechanische Ermüdungsversuche werden grundsätzlich dehnungsgeregelt durchgefüh…
Heterogeneous catalytic transformations are responsible for improving the quality of everyday life. The society now faces grand challenges in energy sustainability. A catalytic site consists of one or many atoms arranged into a particular configuration that provides an ideal electronic structure and geometric environm…
Nanoindentierungsverfahren haben sich inzwischen etabliert als eine wichtige Methode, um die mechanischen Eigenschaften komplexer und heterogener Werkstoffe lokal auf kleiner Skala zu bestimmen. In diesem Kapitel wird insbesondere die für Material- und Werkstoffwissenschaftler wichtige Anwendungsseite der Nanoindentie…
As the use of sandwich structures continues to increase rapidly for applications ranging from satellites, aircraft, ships, automobiles, rail cars, wind energy systems, and bridge construction (to mention only a few), lightweight and high strength structures have become indispensable to many high-tech industries such a…
The marginal oscillator is developed for the spectrometers of continuous action NQR, NMR. A sensor works in a frequency range 2-50 MHz and provides the regulated level of high-frequency tension in the interval of 10-500 mV on LC contour. An involute on frequency is carried out within the limits of 300 kHz. Except the…
