جفت شدن آلدهیدها با ارتوآمینوفنول و حلقه زایی ارتوهیدروکسی آریلیدین آنیلین ها یا بازهای شیف فنولی دو روش کلاسیک برای تهیه بنزواکسازول می باشد. در این کار nano-?-al2o3/bf3-nرا به عنوان یک اسید جامد تهیه نمودیم که برای اثبات وجود اتم b در nano-?-al2o3 طیف های xrd, ft-ir نانو گاما آلومینا و نانوگاما آلومینا بورتری فلورید را به طور جداگانه بررسی نمودیم. در این کار تحقیقاتی مشتقات 2-هیدروکسی آریل-...
The development of high performance nano-electron-emitter arrays with well reliability still proves challenging. Here, we report a featured integrated nano-electron-emitter. The vertically aligned nano-emitter consists of two segments. The top segment is an intrinsically lightly n-type doped ZnO nano-tip, while the bottom segment is a heavily p-type doped Si nano-pillar (denoted as p-Si/ZnO nan...
Norovirus is the leading cause of gastroenteritis worldwide. Despite recent developments in norovirus propagation in cell culture, these viruses are still challenging to grow routinely. Moreover, little is known on how norovirus infects the host cells, except that histo-blood group antigens (HBGAs) are important binding factors for infection and cell entry. Antibodies that bind at the HBGA pock...
thought. 4) In the next experiment, the researchers combine one established group of nano-bots with another. These two groups have applied their sound-systems in different ways: they speak different languages. When first set a task, the two groups cannot collaborate and stay separate. But gradually, through the process of achieving goals, the two groups learn each others’ languages. (They speak...
With a dramatic rise in complexity, needs of nanotoxicology research go beyond simple forms of nanomaterials. This study compared the phototoxicity of nano-TiO2 and graphene-TiO2 nanocomposite (GNP). GNP was synthesized based on a hydrothermal method, which simultaneously performed the reduction of graphene oxide and nano-TiO2 loading. A series of acute toxicity tests of nano-TiO2, graphene and...
