The Preparation of Rutile TiO2 Nanopowders, Phase Transformation and Their Photocatalysed Properties
Online since: June 2005
Authors: Lian Gao, Jing Sun
The high activity of the as prepared lab-made rutile was attributed to the abundance of
hydroxy groups in powders, which was proved by TG data, making the degradation reaction have
more active sites.
The transformation from anatase to thermodynamically stable rutile during heat treatment is usually associated with the reduction in the specific surface areas and the growth of crystalline size, which will decrease its photocatalysed activity obviously.

It provides a solid link between the defined systems and the output data.
The atomic analysis results were presented using the data analysis and graphing software ORIGIN [27].
The data results listed in Table 6 and their comparison in Figs. 6 and 7 provide more explanation.
The observed behavior differs from previous studies; however, it still provides valid and relevant data.

Here we present preliminary data concerning the synthesis of Pt/MWCNTs through the intermediate formation of PtOx particles on the surface of MWCNTs.
Our data show that the samples with large Pt loadings on MWCNTs can be obtained with a stoichiometric amount of alkaline agent (Na2CO3 /Pt 3/1) and without the need in capping agents.
The data indicate the formation of rather small and isolated Pt particles, which are uniformly distributed over the surface of MWCNTs.
The TEM data corresponded well to the results of chemisorption measurements (Table 1).
Both TEM and chemisorptions data indicate that smaller Pt particles form on MWCNTs(350) as compared to MWCNTs(120).

Authors: Hong Song Hu, Jian Zhong Yu, Wu Hao, Fang Wang
Some analysis of the unit’s thermodynamic performance is carried out from the test data for improving such kind of machine afterward.
A reduction of the compression efficiency and heating capacity causes the decline of COP and economical efficiency at the same time.
According to the consequence of the experiments data , the R407C combined unit as a heat pump water heater work in appropriate function no matter in summer mode or in winter mode, its advantage and disadvantage present obviously.

Such
experiments were conducted to establish a reference set of data to which the results from the
dielectrophoresis experiments could be compared.
I-V (conductance) data.
Conductance data obtained from break junction experiments and dielectrophoretic wire growth are presented in Fig. 3 and Fig. 4 respectively.
The data are expressed in terms of the conductance increment G0 = 2e 2/h, derived from the density of states (DOS) available to charge carriers in a reduced-dimensional system [18-20].
Conductance data for dielectrophoretically-grown wires from gold nanoparticles stabilized by (a) PVP in water and (b) ODT in dodecane.

Its performance is demonstrated on nonlinearly mixed speech data..
Each has 36000 data points, and its sampling rate is 8 kHz.
The data are collected by us.
Fig.1 (a) The training speech data used to roughly estimate the AR parameter of s1 and s2; (b) The testing speech data, which is to nonlinearly mix.
The mixed observable data are firstly mapped on the expanded space, where suitable dimension reduction are done by prewhiten processing.

All measurement processes produce results for which the appropriate data analysis is performed.
Analysis " PG-05-07-ANX-1 Data processing techniques To calculate the costs of execution of an activity, general information concerning the costs of the recoded activity is appended to these records.
When direct data allowing to calculate the probability of a failure mode are not available or this failure form is complex, it is proposed the elaboration of a fault tree.
Its probability is calculated based on the probabilities of the basic events and undeveloped events to be evaluated from available historical data.
Costs data of the integrated management system are linked to a worksheet in which are kept current total costs of implementation of all activities under the integrated management system.

Therefore, it is useful to identify and apply a model prediction from available data.
Predicted values will then be compared to experimental data.

In industrial metrology, the system of fringe projection for the fast determination of 3D surface data has been established.
The calculation of 3D data will be described in following chapters.
In general, a diffuse reflection must take place to get data.
The calculation of 3D data within these systems is always based on triangulation.
