according to recent achievements in nano technology we can see its effects in different engineering fields. in nano manufacture process the first essential step is modeling coordinately in order to make it available different software are developing for this propose.  in this paper nano modeling for two papers is developed first understanding structure in nano and micro size and second simulati...

Three homeobox genes, one from Drosophila melanogaster (Drosophila Hmx gene) and two from mouse (murine Hmx2 and Hmx3) were isolated and the full-length cDNAs and corresponding genomic structures were characterized. The striking homeodomain similarity encoded by these three genes to previously identified genes in sea urchin, chick and human, as well as the recently cloned murine Hmx1 gene, and ...

Oktahidro-1,3,5,7-tetranitro-1,3,5,7-tetrazosin (HMX) askeri ve endüstriyel uygulamalarda yaygın olarak kullanılan nitramin türevi bir patlayıcıdır. HMX benzeri özelliklere sahip patlayıcılar için duyarlılık önemli parametredir. Duyarlılığın düşürülmesi sayesinde ısı, sıcaklık, çarpma, sürtünme ile statik elektrik deşarjı gibi çeşitli olayların oluşmasıyla meydana gelebilecek kontrolsüz patlama...

The closely related Green–Kubo and Helfand moment approaches are applied to obtain the thermal conductivity tensor of β-1,3,5,7-tetranitro-1,3,5,7-tetrazoctane (β-HMX) at T=300 K P=1 atm from equilibrium molecular dynamics (MD) simulations. Direct application formula exhibits slow convergence integrated values even for long (120 ns) simulation times. To partially mitigate this we developed a nu...

Luminescent micelles are extensively studied molecular scaffolds used in applied supramolecular chemistry. These particularly important due to their uniquely organized structure and chemically responsive physical optical features. Various luminescent tags can be incorporated with these amphiphilic create efficient probes that utilized as “chemical noses” (sensors) for toxic hazardous materials,...

the purpose of this study was to produce oil in water nano-emulsion by ultrasonication, and investigate the influence of inulin and β-cyclodextrin on the prosperities of nano-emulsion and morphology of spray dried microcapsules. the results showed that emulsion droplet size in samples containing β-cyclodextrin (8.28±0.11 nm) was less than inulin samples (97.12±4.2 nm). considering sem photos, β...

The effect of elastic energy on nucleation and disappearance of a nanometer size intermediate melt (IM) region at a solid-solid (S1S2) phase interface at temperatures 120 K below the melting temperature is studied using a phase-field approach. Results are obtained for broad range of the ratios of S1S2 to solid-melt interface energies, k(E), and widths, k(δ). It is found that internal stresses o...

Der thermische Zersetzungsproze8 bei BMX Die thermische Zersetzung von HMX wurde untersucht oberhalb und unterhalb seines Schmelzpunktes unter Einsatz der Thermoanalytik und der lnfrarotspektroskopie. Der Gewichtsverlust, der auftritt, wenn die Temperatur mit konstanter Geschwindigkeit erhoht wird, laSt sich vier Elementarprozessen zuordnen: lnduktionsperiode, Sublimation, Festphasenreaktion 1....

This study investigated the acute and subchronic inflammatory effects of micrometer-size (micro-size) and nanometer-size (nano-size) particles after intratracheal (i.t.) installation in mice. The role of the type of compound, polymorphism, and size of the particles was investigated. Studied compounds were the two micro-size reference quartzes, SRM1878a and DQ12, a micro- and nano-size rutile ti...
