Abstract Benzothieno[3,2‐b]benzothiophene (BTBT) is an excellent organic transistor material, and its charge‐transfer salt (BTBT)2PF6 is an organic metal that exhibits conductivity as high as 1500 S cm–1 at room temperature. Here, we report a charge‐transfer salt of the selenium analogue, benzoseleno[3,2‐b]benzoseleno…
Reactions of Ph2SbCl3 with RSi(OH)3 [where R = tert-Bu, cyclo-C6H11] and Ph2Si(OH)2 in toluene in the presence of triethylamine as a base were performed. Single-crystal X-ray structural elucidation of the products revealed the formation of hexanuclear antimony(V) and mixed-valent antimony (III/V) oxo-hydroxo clusters…
In this work, a novel waste-to-resource strategy to convert waste bacteria into a useful class of cathode materials, lithium metal phosphate (LiMPO4; M = Fe, Mn), is presented. Escherichia coli (E. coli) bacteria used for removing phosphorus contamination from wastewater are harvested and used as precursors for the sy…
The anilide-bis(aryloxide) proligands H3[ONO(R)] (where H3[ONO(R)] = 2,6-(3-R(1)-5-R(2)-2-hydroxybenzyl)-4-tert-butyl-N-tolyl-aniline; H3[ONO(tBu)], R(1) = (t)Bu, R(2) = Me; H3[ONO(Me)], R(1) = Me, R(2) = (t)Bu; H3[ONO(Me2)], R(1) = R(2) = Me) were synthesized from 2-bromo-5-tert-butyl-isophthalic acid dimethyl ester…
We report that a chiral inorganic compound CrSi exhibits weak ferromagnetism.Temperature dependence of magnetization showed that MnSi exhibited a magnetization anomaly, which is a unique imprint from ferromagnetic to chiral helimagnetic transition, and a experimental evidence of chiral magnetic soliton formation.Howev…
An outwardly propagating spherical flame has been used to characterise the influence of water addition on the combustion of variable steelworks gas compositions. Attention was given to the ratio of hydrogen and carbon monoxide within blast furnace gas, and the catalysing influence of water addition on the preponderant…
Multilayer woven fabrics are conventionally represented with the usual weave notation of black and white squares. This notation is based on the top view of the woven fabric. Side view of multilayer woven fabrics contains more important information, namely the routes of warp yarns between layers of weft yarns. In this…
We measured the X-band electron spin resonance (ESR) in the family of ternary Eu pnictides with structure CaAl2Si2 – type (sp.gr. P3 m1). Temperature dependences of position and width of resonance line well described by the contribution of the form (T- ) ( >0) and = TN or = c-w; TN, c-w Neel and the Curie-Weis…
Risk assessment and subsequent risk management of environmental contaminants can benefit from early collaboration among researchers, risk assessors, and risk managers. The benefits of collaboration in research planning are particularly evident in light of (1) increasing calls to expand upon the risk assessment paradig…
The ever increasing consumption of non-renewable fossil fuels for global economic development leads to serious energy crisis and environmental pollution. Consequently, new alternative fuels and high-efficiency combustion are required to aid the sustainable development of human society. The present paper took the RP-3…
This paper addresses the numerical prediction of NOx emissions from a micro turbine generator (MTG) using a chemical reactor network (CRN). In particular, the effect of fuel composition on NOx formation is analyzed. The numerical predictions are compared with available experimental results. The results obtained with t…
The graphene nanoribbon (GNR) tunneling field effect transistor (TFET) has been a promising candidate for a future low power logic device due to its sub-60 mV/dec subthreshold characteristic and its superior gate control on the channel electrons due to its one-dimensional nature. Even though many theoretical studies h…
The lateral and vertical distributions of organic p/n bulk heterojunctions for an organic solar cell device are, respectively, investigated using nanometer-scale Auger electron mapping and using X-ray photoelectron spectroscopy (XPS) with Ar gas cluster ion beam (GCIB) sputtering. The concentration of sulfur, present…
The macrokinetics of Hg 0 oxidation by a vaporized multicomponent oxidant (MO) that was composed of Fenton reagent, peroxyacetic acid (PAA), and NaCl was evaluated. The effects of various influencing factors on Hg 0 oxidation were investigated, such as MO constitutions, MO pH, reaction temperature, and coexistence gas…
A simulation study of high-pressure lifted flames in a constant-volume chamber has been conducted using detailed reaction mechanisms in CFD to investigate ignition times, flame lift-off lengths, soot production, and fuel effects. The fuels considered include n-heptane, a two-component surrogate fuel (SR), conventional…
This article presents a novel electromagnetic structure that is able to switch a reflector and absorber for multi-functional X-band environments. The periodic structure of a split-ring resonator is employed as an electric LC resonator. The switching between absorption and reflector mode is achieved by connecting or di…
The unipolar resistive switching characteristics of the amorphous LaLuO3 thin films deposited by pulsed laser deposition have been studied. Reliable and repeatable nonvolatile switching of the resistance of LaLuO3 films was obtained between two well defined states of low and high resistance with nearly constant resist…
Abstract The failure of the boiler tubes occur due to various reasons like creep, fatigue, corrosion and erosion. This paper highlights a case study of typical premature failure of a final superheater tube of 210 MW thermal power plant boiler. Visual examination, dimensional measurement, chemical analysis, oxide scale…
Abstract An attempt is made to study the hot corrosion behaviour of Inconel 617 under mixed salt environment (Na 2 SO 4 , NaCl and/or V 2 O 5 ) at 900 and 1000 °C. The results were analysed and discussed with respect to mass change, XRD, optical image and SEM/EDAX. The oxide scales are enriched with Ni, Cr, Mo and Co…
