پژوهش ها نشان می دهند که خواص لایه های کربنی شبه الماس (dlc)می تواند با برخی خواص منحصر بفرد الماس رقابت کند. به منظور بهبود یافتن برخی خواص dlc مانند رسانندگی الکتریکی، پایداری گرمایی و غیره، لایه های کربن شبه الماس- فلز (me-dlc) معرفی شده اند. در این تحقیق، لایه های کامپوزیت شامل نانوذرات طلا در آرایه ی dlc و بر روی زیرلایه های شیشه ای، در توان و فشار ثابت و در دمای محیط، به روش rf-pecvd انبا...

Abstract A primary target towards the clean-up operation of Fukushima disaster is retrieval Molten Core-Concrete Interaction (MCCI) products, presently residing on basement damaged nuclear reactor Units 1–3. MCCI a fusion materials, composed both fuel cladding and neighbouring structural components. Determining currently unknown, physical mechanical properties essential for successful timely re...

The UK public sector provides an important opportunity for firms to transact business with an attractive customer. However there is concern that public procurement processes place smaller firms at a disadvantage. The views of small firms are under-represented and this paper provides additional, new evidence in order to improve our understanding of their difficulties with public procurement. A U...

We derive a relation between the observed polarization and beaming factor (Doppler factor) and compare this relation with the observed data for BL Lac objects. Our results indicate that the high optical polarization is correlated to the beaming effect and the difference in polarizations between Xray selected (XBLs) and radio selected (RBLs) BL Lac objects is due to the difference in their beami...

The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...

The interaction between the ejecta from Supernova 1987A and surrounding material is producing steadily brightening radio and Xray emission. The new-born supernova remnant has been significantly decelerated by this interaction, while its morphology reflects the axisymmetric nature of the progenitor wind.

A comparative XMM-Newton archival data spectral study of the ultraluminous Xray source (ULX) M33 X-8 has been performed by using both the standard disk model and the newly developed slim disk models. The results of this analysis tend to confirm the hypothesis that M33 X-8 is an X-ray binary with a stellar-mass black hole accreting at super-Eddington rate.

Recent breakthroughs in ultrafast photonics in the mid-IR help understand complex interactions of high-intensity mid-IR field waveforms with matter, offer new approaches for xray generation, enable mid-IR laser filamentation in the atmosphere, facilitate lasing in filaments, give rise to unique regimes of lasermatter interactions, and reveal unexpected properties of materials in the mid-IR range.
