We selecte two bentonite products: activated clay and organo-bentonite, and introduce the related content of them like industrial applications, technology and raw materials of producting at the same time. After that, we choose the preparation processes of activated clay and organo-bentonite. Choose conditions of the prepared samples, arranging test methods by orthogonal test program, and preparing of the activated clay and organo-bentonite samples in accordance with the different test conditions. Finally, we draw this conclusion according to the test analysis and demonstration results. We propose the recommendations of the development of activated clay and organo-bentonite by Hongquan bentonite, pointing out that the shortcomings of this study and proposing pilot study of future.

Six tropical biomass samples namely: Ogbono wood (Irvingia wombolu), Mango wood (Mangifera indica), Neem wood (Azadiracta indica), Ogbono shell (Irvingia wombolu), Ogirisi wood (Neubouldia laevis) and Tropical Almond wood (Terminalia catappa) were pyrolyzed in a bench scale screw reactor at 450oC. The physicochemical properties of the samples were determined prior to the pyrolysis experiments. The bio-oil and bio-char produced were similarly characterized using standard procedures established by American Standard and Test Methods (ASTM). The highest bio-oil yield of 66 wt% and least bio-oil yield of 53 wt% were obtained from Neem wood and Tropical Almond wood respectively. The characterization results of the products show that even though the moisture content of the bio-oil was quite higher than those of the original feedstock, their higher heating values were higher than those of the parent feedstock. Both characterization results show that the feedstock and their fast pyrolysis products are good materials for bioenergy production. The Gas Chromatography Mass Spectroscopy (GC-MS) analysis of the bio-oil shows the presence of useful chemicals such as phenols and levoglucosan, which could be harnessed for industrial applications.

For the realization of environmental compatible tribosystems within the special research centre SFB 442 PVD coated systems are developed, which improve the tribological characteristics together in interaction with compatible lubricants. For the evaluation of coated substrate systems employed in tribosystems, it is significant to characterize the mechanical stress collective within the systems by means of their mechanical properties. Subject of the presented investigations is an analysis about the properties of the systems that have significant effects on the system stress collective. Differences to the well-known surface stress of solid materials are pointed out and mathematical models for the description are developed to describe the influence of coated substrates. The aim of these investigations is to draw a connection between these stresses occurring in tribosystems (e.g. industrial applications bearings) and the loads applied in test methods e.g. microindentation (Rockwell Hardness Tests) and nanoindentation. To evaluate the stresses applied in real tribosystems the theory of micro contact mechanics of Greenwood and Williamson is used and is found to be appropriate. Since, only with this connection it is possible to consult the results gained in the coating test methods for the evaluation of a coated system. Essential aid in here is the simulation of the mechanical surface stresses by means of FEM (finite element method). At this point it is possible to take the anisotropic and inhomogeneous material properties of the coating material and the substrate into account.

Researchers at the National Institute of Standards and Technology (NIST) have developed a set of draft standard test methods for measuring and promoting software agility in industrial robots. These test methods are being used as the basis for an upcoming competition called the Agile Robotics for Industrial Applications Competition (ARIAC). ARIAC is being used to promote and push forward the state of the art in software agility and enable technology transfer between academia and industry. This paper describes the background about the test methods, how they were developed, how they will be applied to the ARIAC Competition, and additional information about the ARIAC Competition.
