The application of mass spectrometric techniques for the analysis of the complex mix‐ tures inherent in fuel and lubricant samples will be examined. These samples because they are naturally complex mixtures, typically requires either very high resolution mass spectrometry or one of the hyphenated techniques gas chromatography‐mass spectrometry(GC‐MS) or liquid chromatography‐mass spectrometry (...

The interaction between nano-SiO2 and lysozyme was investigated by the method of UV-Visible  detection and fluorescence spectroscopic techniques. The thermal denaturation of lysozyme has been investigated in the presence and absence of nano-SiO2 over the temperature range (293-373) K in different buffers and pH values, using temperature scanning spectroscopy. The presence of nano-SiO2 caused th...

Bone's remarkable mechanical properties are a result of its hierarchical structure. The mineralized collagen fibrils, made up of collagen fibrils and crystal platelets, are bone's building blocks at an ultrastructural level. The organization of bone's ultrastructure with respect to the orientation and arrangement of mineralized collagen fibrils has been the matter of numerous studies based on a...

X-rays are commonly used as a means to image the inside of objects opaque to visible light, as their short wavelength allows penetration through matter and the formation of high spatial resolution images. This physical effect has found particular importance in medicine where x-ray based imaging is routinely used as a diagnostic tool. Increasingly, however, imaging modalities that provide functi...

In this research, Carbon-doped TiO2 nano-photocatalyst is synthesized via sol-gel technique and photo-catalytic degradation of phenol has been studied under ultraviolet and visible light irradiation in a fluidized bed reactor. Various techniques are used to characterize TiO2 nano-photocatalyst such as X-Ray Diffraction, Fourier transform infrared spectroscopy,  Energy Disp...

The effect of various parameters (pH, irradiation time, nanophotocatalyst dosages and temperature) on photocatalytic degradation of Direct Red 23 (DR 23) and Direct Brown 166 (DB 166) using pure InVO4 and InVO4-TiO2 nanocomposite were investigated under visible light irradiation. InVO4 and InVO4-TiO2 wer...

The development and current status of flow injection techniques in inductively coupled plasma atomic emission spectrometry is reviewed. Topics such as direct sample introduction, dilution, calibration and on-line sample pre-treatment are used to illustrate the versatility of the combined experiment. The analytical potential of flow injection techniques in inductively coupled mass spectrometry i...

A new carbon monoxide (CO)-releasing material has been developed by embedding a manganese carbonyl complex, MnBr(bpydc)(CO)3 (bpydc = 5,5'-dicarboxylate-2,2'-bipyridine) into a highly robust Zr(iv)-based metal-organic framework (MOF). Efficient and controllable CO-release was achieved under exposure to low intensity visible light. Size-controllable nanocrystals of the photoactive MOF were obtai...
