Fluorination of BN nanotubes has been performed using a catalytic growth method, which leads to the appearance of markedly curved fluorine-doped BN sheets and converts originally insulating BN nanotubes to semiconductors, as confirmed by the comparative electron transport four-probe measurements on doped and undoped individual BN nanotubes.
Self-report studies suggest that patients with bulimia nervosa (BN) evidence difficulties with interoceptive awareness. Indeed, interoceptive deficits may persist after recovery of BN and may be a biological trait that predisposes symptom development in BN. However, no studies to date have directly assessed interoceptive sensitivity, or accuracy in detecting and perceiving internal body cues, i...
Two-dimensional materials, such as graphene and monolayer hexagonal BN (h-BN), are attractive for demonstrating fundamental physics in materials and potential applications in next-generation electronics. Atomic sheets containing hybridized bonds involving elements B, N and C over wide compositional ranges could result in new materials with properties complementary to those of graphene and h-BN,...
MVA-BN-PRO (BN ImmunoTherapeutics) is a candidate immunotherapy product for the treatment of prostate cancer. It encodes 2 tumor-associated antigens, prostate-specific antigen (PSA), and prostatic acid phosphatase (PAP), and is derived from the highly attenuated modified vaccinia Ankara (MVA) virus stock known as MVA-BN. Past work has shown that the immunogenicity of antigens can be improved by...
جذب تک لایه h-BN بر روی نانولایه WS2 در چارچوب نظریه تابع چگالی و با استفاده از کد محاسباتی کوانتوم اسپرسو بررسی شده است. محاسبات با تابع های تبادلی-همبستگی شامل LDA،GGA و با استفاده از دو رهیافت نیمهتجربی و ابتدا به ساکن با به کارگیری تابعهای DFT-D2، vdW-DF2و vdW-DF2B86R صورت گرفته تا کارایی تابعهای مختلف برای پیشبینی انرژی جذب، مکانیسم جذب و فاصله جذب بین دو لایه h-BN و WS2 بررسی شوند. به...
فرآیند ماشینکاری به روش تخلیه الکتریکی( edm)، یکی از فرآیندهای نوین ماشینکاری است که کاربردهای متنوعی در ساخت و تولید محصولات میکرومتری دارد. رشد و توسعه نانوتکنولوژی و نیاز به بهره گیری از روشهای جدید موجب شده است که جذبه زیادی برای استفاده از فرآیند edm در ساخت و تولید محصولات نانومتری ایجاد شود. فرآیند nano-edm یک فرآیند ماشینکاری حرارتی است که در آن از انرژی حرارتی حاصل از جرقه الکتریکی برا...
abstract this study is an attempt to determine the effect of nano- technology education on science lesson for fifth grade in primary school in the city of kermanshah. this research is experimental and is conducted in the from of pre-test and post- test for the control group. an achievement test was administered to determine the rate of learning in the students. the research is an applied one. ...
For p > 0, let B(Bn) and Lp(Bn) respectively denote the p-Bloch and holomorphic p-Lipschitz spaces of the open unit ball Bn in C . It is known that B(Bn) and L1−p(Bn) are equal as sets when p ∈ (0, 1). We prove that these spaces are additionally norm-equivalent, thus extending known results for n = 1 and the polydisk. As an application, we generalize work by Madigan on the disk by investigating...
Effect of Different Tapered Gutta Percha Cones in Apical Microleakage of Human Root Canal Obturation
Background and purpose: Gutta-percha is generally accepted as the main canal filler. Standard gutta-percha cones are available in 2-10% tapers. The purpose of this study was to compare apical microleakage of canals obturated with different tapers of gutta-percha, using the protein penetration technique. Materials and methods: In this study, 96 maxillary anterior teeth were selected and were pr...
