The control of the crystalline structure and shape (crystal habit) nanoparticles (NPs) is key to controlling their physical chemical properties. Among different metals, crystallogenesis ruthenium NPs has been less studied, until recently, Ru NP crystal morphology have considered as presenting versatility than face-centered cubic (fcc) metals platinum group. Here, we show that while hydrogenatio...
The risk of leukemia and other radiation oriented diseases for astronauts increases with exposure to cosmic radiation. During the space missions, the blood and immune system change and the bones are affected by osteoporosis. In this research, a model, based on the human blood system, is presented for the study of the microgravity and the space radiation effects on the blood cells. This model is...
روش های معمول برای تهیه بنزوتیازول ها شامل تراکم 2-آمینوتیوفنول با کربوکسیلیک اسید ها، آلدهید ها و هم¬چنین ارتواسترها می باشد. در این کار، کاتالیست nano- γ-al2o3/bf3-n به عنوان کاتالیست اسید جامد تهیه شده است. برای تایید ساختار nano- γ-al2o3 و nano- γ-al2o3/bf3-n طیف مادون قرمز و پراش پرتو xگرفته شده است. مشتقهای بنزوتیازول از طریق تراکم آلدهید ها با 2-آمینوتیوفنول با استفاده از nano- γ-al2o...
• GNP incorporated in alumina matrix to deposit composite coatings via SPS. Raman analysis confirmed retention of as-processed coatings. Improved mechanical and tribological properties achieved for Wear mechanisms monolithic coating were revealed. Graphene possesses high fracture toughness excellent lubrication properties, which can be exploited enhance performance systems utilized combat wear....
Background and purpose: Cold storage results in clustering of gpIbα molecules on platelets. Consequently, the lectin domains of αMβ2 receptors on the liver macrophages recognize these molecules and ingest the platelets. Probably coverage of sugar molecules of gpIbα using galactose could prevent the recognition and ingestion of platelets by macrophages. The purpose of this study therby was to...
In the present investigation, thermo-reversible bonds formed between maleimide and furan groups (Diels–Alder (DA)-based bis-maleimides (BMI)) have been generated to enable high-performance unidirectional (UD) carbon fiber-reinforced plastics (CFRPs) with self-healing (SH) functionality. The incorporation of SH agent (SHA) was performed locally, only in areas interest, solution electrospinning p...
introduction: in this study the evaluation of a platelet-based maximum penalized likelihood estimation (mple) for denoising spect images was performed and compared with other denoising methods such as wavelets or butterworth filtration. platelet-based mple factorization as a multiscale decomposition approach has been already proposed for better edges and surfaces representation due to poisson n...
