Data and predictions for the mass burning rates of di-tert-butyl peroxide (DTBP) pool fires (0.003 m < pool diameter < 3 m) are presented. The mass burning rates of DTBP fires are up to five times higher and are less dependent on pool diameter compared to hydrocarbon pool fires caused by an additional heat release rat…
The magnetic and electronic properties of La(4)Ni(3)O(8) are investigated by performing the full-potential linearized augmented plane wave method. The C-type antiferromagnetic spin ordering is preferred and a molecular correlated insulating state with high-spin Ni ions is found. Our results have proved that this insul…
Three different poly(hydroxyalkanoates) (PHAs), copolymers of poly(3-hydroxybutyrate) (P3HB), have been used to make composites using two different fillers, bioactive glass (type 45S5 Bioglass®) and calcium sulfate dihydrate. The PHAs used were poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [PHBHV] and two copolymers of…
The purpose of this study was to propose an analytical procedure that provides the effects of particle size and surface area on dissolution of efavirenz. Five different batches obtained by different micronization processes and with different particle size distribution and surface area were studied. The preformulation…
The concept that equates oxidation and pressure has been successfully utilized in explaining the structural changes observed in the M(2)S subnets of M(2)SO(x) (x = 3, 4) compounds (M = Na, K) when compared with the structures (room- and high-pressure phases) of their parent M(2)S `alloy' [Martínez-Cruz et al. (1994),…
The study of charge transfer complexes is a fascinating area of research due to their unique electronic and magnetic properties. During the last two decades, several interesting properties like superconductivity, charge transport, and magnetic and ferroelectric properties have been investigated in detail except the ma…
The 2-methacryloxyacetophenone (MAP) was prepared and subjected to suspension polymerization with divinylbenzene (DVB). The differently sulfonated MAP–DVB cross-linked copolymer cationic exchange resins were prepared by sulfonation with a fixed volume of concentrated sulfuric acid in an oil bath at 70 oC. Several char…
The selectivity and sensitivity of a benzoindolium heptamethine cyanine dyes toward CN- and F- in DMSO are described. These anions interact with Dye-1 and Dye-2 forming anion-Dye adducts, the formation of which was supported by the Pariser-Parr-Pople molecular orbital (PPP MO) calculation. The different optical respon…
We have synthesized epitaxially grown freestanding FeSi nanowires (NWs) on an m-Al(2)O(3) substrate by using a catalyst-free chemical vapor transport method. FeSi NW growth is initiated from FeSi nanocrystals, formed on a substrate in a characteristic shape with a specific orientation. Cross-section TEM analysis of se…
We report the results of infrared and magneto-optical spectroscopy study on electrodynamic response of bismuth doped with 1.5$%$ of antimony. The spectra are presented for temperatures down to 4.2 K, and in magnetic fields as high as 18 T. The results reveal strong magneto-optical activity, similar to pure bismuth, ho…
The configurations of pixilated detectors for x-ray imaging crystal spectrometers and x-ray pinhole cameras can be optimized based on the Shannon-Nyquist sampling and interpolation theory, since the observed spectra are typically oversampled. The degree of oversampling is quantified and alternative uses for redundant…
High-pressure and high-temperature Brillouin scattering studies have been performed on liquid of composition corresponding to the ammonia dihydrate stoichiometry (NH(3)·2H(2)O) in a diamond anvil cell. Using the measured Brillouin frequency shifts from 180° back- and 60° platelet-scattering geometries, the acoustic ve…
The developing history of polymer materials tells that the invention of novel polymers with excellent performance is generally originated from the synthesis of new polymerizable monomers. Among kinds of monomers, benzocyclobutene (BCB) has attracted much interest because of its unique molecular structure and polymer p…

We investigated the near infrared enhancement in Cu(In,Ga)Se(2) (CIGS)- based solar cells utilizing a hydrogen-doping ZnO (ZnO:H) window layer. The results show that the carrier concentration of ZnO:H film is lower than that of AZO film which can increase the transmittance in the NIR. The advantage of ZnO:H film is hi…

The Earth’s crust contains almost 100 elements and only 8 of them (O, Si, Al, Fe, Ca, Na, K, and Mg) form 98.5% of the crust and compose the base of the soil body. Most of the soil types contain 60% of all existing minerals where the silicates and aluminosilicates are the most dominating ones. They are present in a fo…
Aminopropyl-functionalized SBA-15 mesoporous silica was used as a support to adsorb myoglobin. Then, in order to avoid the leakage of adsorbed myoglobin, lysozyme was covalently tethered to the internal and external surface of the mesoporous silica with glutaraldehyde as the coupling agent. The property of amino-funct…
Rhodamine dyes have been attracted to many researchers due to its excellent photophysical properties. Interesting one of these dyes is rhodamine 6G. In this study, we have designed and synthesized a strong yellowish-green fluorescent emission dye sensor based rhodamine 6G for the detection of Hg2+ ions. It has noticea…
The previously reported high-spin Cr(II) compounds CpCr(C 6 H 4 CH 2 NMe 2 ) ( 1 ) and CpCr[C(Ph)C(Ph)C 6 H 4 CH 2 NMe 2 ] ( 2 ) were investigated as precursors to CpCr(III) complexes. Single-electron oxidation of 1 was used to prepare CpCr(C 6 H 4 CH 2 NMe 2 )(X) for X = I ( 3 ), OTs ( 4 ), O 2 CPh ( 5 ), OCMe 2 Ph (…
