Water pollution from textile industries is a major concern with respect to the availability of clean drinking water. The removal of textile (organic) dyes through photocatalytic degradation with pure WO3 and titanium (IV) doped tungsten oxide [Ti (IV)-WO3] nanospheres were studied under visible light. The WO3 and Ti (IV)-WO3 nanospheres were synthesized via microwave-assisted method at microwave power of 160 W for the duration of 20 mins. The as synthesised WO3 and Ti (IV)-WO3 nanospheres were characterized for their structural, microstructural, and spectroscopic properties by using powder X-ray diffraction (XRD), UV–Visible (UV-Vis) spectroscopy, Fourier-transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and High-resolution transmission electron microscopy (HR-TEM). The X-ray diffractograms confirmed the formation of highly pure WO3 and Ti (IV)-WO3 nanospheres. The average crystallite size of WO3 and Ti (IV)-WO3 nanospheres were calculated as 53.37 nm and 35.24 nm respectively using Debye Scherrer equation. The bandgap of Ti (IV)-WO3 was found to be decreased to 2.5 eV from 3.2 eV (WO3) respectively. It can be deduced that Ti (IV)-WO3 can be utilized as efficient visible light (λ>420 nm) driven photocatalyst as the bandgap was < 3 eV. The agglomerated spherical nanoparticles were seen for WO3 and Ti (IV)-WO3 in the HR-TEM images. The photocatalytic activity of textile dye was analyzed by UV-Vis spectrophotometer under visible light. The photocatalytic organic dye degradation was investigated. The enhanced photocatalytic activity of titanium (IV) doped tungsten oxide (10 wt%) was observed to be ~100% in 100 mins. This makes titanium (IV) doped tungsten oxide nanospheres, a potential nanomaterial for water purification.

Several types of waterside corrosion can attack a boiler. In many cases, the only evidence of this corrosion before tube failure is increased hydrogen in the steam. A continuous record of this hydrogen can be obtained with dissolved hydrogen analyzers which utilize the hydrogen's high thermal conductivity to detect as little as 0.2 ppb in steam. Rate of metal loss can be calculated from the amount of hydrogen in the steam, and the pattern of hydrogen release often indicates the type of corrosion. A well planned test program includes tests for sources of hydrogen other than corrosion.

RESEARCH JUST COMPLETED AT THE OHIO STATE UNIVERSITY ON FACTORS LIMITING PLASTIC STRAIN UNDER A NOTCH (OR CRACK) MAY PROVE IMPORTANT IN ELUCIDATING CERTAIN ASPECTS OF PLASTIC ZONE BEHAVIOR IN STRESS CORROSION CRACKING. IT WAS FOUND THAT THE PLASTIC ZONE AT THE TIP OF THE CRACK EXPANDS ON LOADING UNTIL A CRITICAL STRAIN AT THE NOTCH ROOT IS ATTAINED. AT THIS STRAIN, THE MATERIAL UNDERGOES A RHEOLOGICAL TRANSFORMATION INTO FLUID-LIKE FLOW (VISCO- PLASTIC), IN WHICH IT IS SUSCEPTIBLE TO LOCALIZATION OF FLOW ALONG "CHARACTERISTICS" (SLIP LINES IN FIELDS), WHICH ARE DIRECTIONS OF CRITICAL MAXIMUM SHEAR STRESS AND ALSO DIRECTION OF PURE SHEAR. PLASTIC INSTABILITIES MAY BE MOUNTED ALONG THESE DIRECTIONS. WEAK INSTABILITIES LEAD TO STABLE SLOW CRACK PROPAGATION; STRONG INSTABILITIES LEAD TO UNSTABLE FAST PROPAGATION (BRITTLE FRACTURE). AGGRESSIVE CHEMICAL ENVIRONMENTS MAY AFFECT ONE OR BOTH OF THESE NEW MATERIAL PARAMETERS WHICH HAVE BEEN DISCLOSED, NAMELY THE CRITICAL STRAIN AT WHICH FLOW IS CONCENTRATED ALONG CHARACTERISTICS AND THE NATURE OF THE INSTABILITIES (STRONG OR WEAK) THAT CAN BE GENERATED ALONG CHARACTERISTICS. PLASTIC ZONE BEHAVIOR, THUS, INVOLVES METALLURGICAL STRUCTURE, RHEOLOGY, AND FORMAL PLASTICITY THEORY. /AUTHOR/

INHIBITORS MUST BE CAREFULLY CHOSEN TO FIT THE PARTICULAR APPLICATION REQUIRED. THE 5000 SERIES ALLOYS, CONTAINING MAGNESIUM AS THE MAJOR ALLOYING ELEMENT, ARE SHOWN TO HAVE GREATER CORROSION RESISTANCE IN SALINE MEDIA THAN DO THE 1100 OR HIGH-PURITY ALLOYS. JEL-TYPE INHIBITORS SUCH AS AGAR-AGAR, BLOCK THE CATHODIC REACTIONS, CAUSING MARKED CATHODIC POLARIZATION. AMINE INHIBITORS ALSO AFFECT THE CATHODIC CHARACTERISTICS. THEY SHOULD PROVE USEFUL IN INHIBITING ALUMINUM CORROSION IN ACID MEDIA. CHROMATES ARE EFFECTIVE ANODIC INHIBITORS.
