Sorption of gases in micro- and mesoporous materials is typically interpreted on the basis of idealized structural models where real structure effects such as defects and disorder are absent. For covalent organic frameworks (COFs) significant discrepancies between measured and simulated adsorption isotherms are often reported but rarely traced back to their origins.

PAn (polyaniline) and PAn/ZnO photocatalysts were synthesized using chemical polymerization of aniline. The structure characterization of the synthesized samples was analysed by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV-Vis spectroscopy measurements, and thermal gravimetric analysis (TGA). The photocatalytic activities of PAn and PAn/ZnO (0.

The measurement methods using structured light have the advantage of being fast, accurate, and noncontact with the surface of the object. However, these methods have reached its limitation when measuring mechanical details with high surface gloss, due to the unpredictable reflection of incident rays after reaching to object’s surface that, consequently, leads to the simultaneous appearance of several regions with different brightness.

The optical properties, morphology and structures of ZnO:Cu NRs were investigated through out of measurement the scanning electron microscopy, X-Ray diffraction and ultraviolet-visible spectroscopy, respectively. The results show the Cu doped ZnO NRs were uniformly and dense grown on mogul substrates, well oriented in the (002) plane. Additionally, the light absorption can be significantly enhanced to more 10% in a wide spectral range (400-800 nm) due to the reduce reflection.

The study result shows that the light intensity on bright skin should be 6 – 12, dark or brown skin should be 14 – 20, average skin color should be 9 – 15 for the best result. The studying on suitable lighting mode with each skin color is very important for the accuracy of 3D measuring method to support the beauty processes or glove designing better.

In this paper, an algorithm to detect multiple planes on point cloud data was developed based on RANSAC algorithm to evaluate the accuracy of point cloud measured by structural light. To evaluate the accuracy of the point cloud obtained, two-step height parts are used. The planes are detected and the distance between them needs to be measured with high accuracy

Recently, striking effects of light irradiation on the magnetic state were reported for Prussian blue (PB) analogues AxCoy[Fe(CN)6] (A = Na, K, Rb, Cs). The physical and optical properties of these compounds are dependent on the size of the particles of the measured samples. However, there have been few reports on the formation of nano-sized particles of the material and the effect of size of the particles on the properties of the compounds.

This research paper focuses on horizontal and vertical diversification of specialised homegardens. The study location was Central Kerala region consisting of Thrissur, Palakkad and Ernakulam districts due to the presence of specialized homegarden system. A total of 60 homegarden farmers were selected, to assess the horizontal and vertical diversification of specialized homegardens. Respondents were personally interviewed and data were enumerated from the homegardens with components of specializations so as to get sufficient data from for interpretation.

Catalyst TiO2 with N-doped, Mg-doped and N-Mg co-doped were created by impregnation method with Mg(NO3)2 (add Mg in) and mix method with urea (add N in). The XRD, SEM, DR, BET, FT-IR measurements were carried out for structural characterization of the TiO2 samples. The result performed, compared with the sample of initial TiO2-P25 particle size and specific surface area, samples of doped-catalyst changed insignificantly.

In a structured light system, calibration is an important step for estimating the intrinsic and extrinsic parameters of the camera and projector. System calibration errors directly affect the measurement errors. Therefore, the accurate calibration is the main prerequisite for a successful and accurate surface reconstruction. In this paper, the effect of checker size and checkerboard angle on the accurate calibration for a structured light system is presented.

TiO2-Fe@CNTs nanocomposite materials were synthesized by hydrothermal route in Teflon-sealed autoclave at 180˚C for 10h. The FESEM and X-Ray diffraction measurements were taken for morphology and structural analysis of TiO2 nanoparticles doped with Fe coating on CNTs. The effects of the iron and CNTs on the enhanced photocatalytic activity for methylene blue degradation under AM 1.5 illumination of 100 mW.cm−2were investigated.

Despite its significant role in bone adaptation, its detailed structure remains elusive: light microscopy can barely detect the entire jungle at the best resolution, let alone individual fibers in the matrix surrounding the cell. Wang’s team relies on a bioimaging approach called Fluorescence recovery After Photobleaching to measure how fast a small fluorescent dye and a relatively large protein move through the pericellular matrix. The researchers record differential speeds of the large and small molecules.

We measured cocrystals of the membrane protein Photosystem I with its soluble electron acceptor ferredoxin for the first time at the ALS (Berkeley, CA). Previous data collected at our home source and at other synchrotron sources showed crystals with very high mosaicity (2–5%) and a diffraction limit to 7–8 Aresolution. This first beamtime at ALS was very successful and may represent a breakthrough for the determination of the crystal structure. 110 crystals, grown under modified crystallization conditions, were scanned and for the first time, crystals diffraction to 3.5 A were observed....

We present measures of board structure for the restating and control samples in panel B of Table 5. The two groups of firms have similar board structures. The median board size for restating (control) firms is 7 (8) members. The median proportion of independent directors (PID) is about 71 percent in each sample. About 5 percent of the independent directors hold 5 percent or larger blocks of equity (PID5) in both groups. One striking difference between the two groups is in the incidence of an independent director with financial expertise (IDFE).

This book is a comprehensi ve and illustrated work on high temperature air combustion (here called HiTAC), which has revolutionized our paradigm on the use of all kinds of fossil, alternative, waste, and derived fuels for energy conversion and energy utilization in industry. Significant experimental knowledge and insights from many practical devices have resulted in the utilization of HiTAC technology for many applications. The traditional definition of flame is that which gives heat and light during chemical reaction between reactants.
