The twin boundary damping peak and the transformation damping peak constitute the temperature dependent damping behavior in Mn–Cu alloys. In order to observe the effects of twinning microstructure on the twin boundary damping behavior, a Mn–30 at%Cu alloy was finally treated by furnace cooling (FC) and aging after wat…
The inhibiting effect of several acetylenic alcohols, namely 2-butyn-1-ol, 3-butyn-1-ol, 3-pentyn-1-ol and 4-pentyn-1-ol has been investigated on the corrosion of iron in 1 M HCl. The Tafel extrapolation method, linear polarization resistance and electrochemical impedance spectroscopy illustrate their inhibiting effec…
ESDU International of London, UK, has recently published a User Guide [1] 2003. “Engineering Sciences Data Unit”. In Fouling in Cooling Systems Using Seawater, London, , UK: ESDU International Ltd.. ESDU Item 03004 [Google Scholar] on fouling in heat exchange systems using seawater as the coolant. Developed over a per…

Lithium ferrite was investigated with a view to its application as a new CO2 absorbent capable of absorbing CO2 at around 500°C and emitting CO2 at temperatures of less than 750°C. From the TG analysis, equilibrium temperature of lithium ferrite, at which CO2 absorption apparently stops and emission starts, is found t…
Many of Michigan's loamy soils exhibit varying degrees of fragipan expression, which may be variously influenced by their parent materials. We examined three soils in northern Michigan with varying degrees of fragipan expression to assess development of fragipans formed in acidic and calcareous glacial drift. To accom…
The rapid diffusion of H in metals permits an easy segregation to the grain boundary and an easy trapping to the vacancy. H-induced intergranular embrittlement in metals such as Fe and Ni is generally a result of coalition of segregated H and other embrittling impurities at the grain boundary. Ab initio total energy c…
A series of two-dimensional (2D) oxalate-based compounds, namely [N(n-C4H9)4][M(II)Cr(III)(ox)3] (M(II) = Mn, Fe; ox = C2O4(2-)) and [N(C2H5)(n-C3H7)(n-C4H9)(n-C5H11)][M(II)M(III)(ox)(3)] ((M(II), M(III)) =(Mn, Cr), (Fe, Cr), (Mn, Fe)) were synthesised starting from racemic tris(oxalato)metalate: rac-[M(III)(ox)3]3- (…
A low-temperature chemical bath deposition (CBD) technique has been used for the preparation of Mn 3 O 4 thin films on glass substrates. The kinetic behavior and the formation mechanism of the solid thin films from the aqueous solution have been investigated. Structure (X-ray diffraction and Raman), morphological (ato…
Crystallized B13C2 thin films were fabricated by intense pulsed-ion beam evaporation (IBE) method. Electrical conductivity and Seebeck coefficients of the obtained films were 1×10—4 l/Ωm and 200 μV/K at 1000 K, respectively. These values were comparable to those of bulks. For the application of the thin films, since r…
Highly organized mesoporous titania and silica thin films were synthesized using a triblock copolymer-templated sol-gel method via an evaporation-induced self-assembly (EISA) process. For the first time, we have found that the mesophase of these metal oxides can be selectively controlled by varying the spin-coating co…
Silica becomes increasingly used in chemical, pharmaceutical, and (nano)technological processes, resulting in an increased demand for well-defined silicas and silica-based materials. The production of highly structured silica from cheap starting materials and under ambient conditions, which is a target for many resear…
Performance of porous zinc electrode in alkaline secondary battery systems suffers mainly from shape change and dendrite growth. Polyaniline coating in direct contact with porous zinc electrode was found to restrict zincate movement away from the test electrode, which otherwise may lead to a decrease in electrode surf…
Benthic diatoms, which often dominate marine biofilms are mostly pennate along with a few centric species that have an attached mode of life. Even though the range of diatoms in biofilms is diverse, their ecology is poorly understood because of the difficulty in sampling and enumeration. Scraping or brushing are the t…

Unit-cell parameters, Raman scattering profiles and DTA curves were measured on monoclinic tridymite from fired silica brick. Ten peaks appear in the Raman measurements from 100 to 1250 cm−1 at 25°C, and their positions and widths show no significant change up to 110°C. The monoclinic unit-cell parameters, a, b, c and…
ABSTRACT Fractions from the sorghum dry milling industry, including bran, are a potential source of kafirin. Free‐standing plasticized cast films were prepared from defatted kafirin preparations from red and white sorghum flour and bran fractions, and from commercial zein. All the kafirin preparations were able to for…
Many highway agencies have been using Geographic Information System (GIS) for analyzing accident data. Identification of problematic locations is one of the most important aspects in accident studies. The GIS based application combines the information collection capabilities with the visualization. The GIS and Road Ac…
New correlations between various CPTU factors, undrained shear strength and overconsolidation ratio have been developed for soft to medium stiff clays. The correlations are based on comparing the CPTU results against undrained traxial compression strength and preconsolidation pressure determined on block samples of ve…
Disc-shaped clay particles (Laponite) with a thickness of 1 nm and a diameter of 25 nm were bridged into a physical gel (shake gel) by poly(ethylene oxide) (PEO) chains under shear. The shake gels formed transformed again into a liquid when the shear stopped. The critical concentrations of Laponite and PEO required fo…
