OBJECTIVES Nanothechnology found to be increasingly implemented in implantology sphere over the recent years and it shows encouraging effect in this field. The aim of present review is to compare, based on the recent evidence, the influence of various nanostructure surface modifications of titanium for implants, on osteoblasts proliferation. MATERIAL AND METHODS A literature review of English...
Green LEDs do not show the same level of performance as their blue and red cousins, greatly hindering the solid-state lighting development, which is the so-called "green gap". In this work, nano-void photonic crystals (NVPCs) were fabricated to embed within the GaN/InGaN green LEDs by using epitaxial lateral overgrowth (ELO) and nano-sphere lithography techniques. The NVPCs act as an efficient ...
Based on the difference in the redox potentials between two metal species, the galvanic replacement reaction is known to create an irreversible process to generate hollow nanostructures in a wide range of shapes. In the context of galvanic replacement reaction, continuing etching leads to the general collapse of the hollow structures because of the excess amount of oxidizing agent. We demonstra...
This essay argues that nano-images would be best understood with an aesthetical approach rather than with an epistemological critique. For this aim, I propose a ‘technoaesthetical’ approach: an enquiry into the way instruments and machines transform the logic of the sensible itself and not just the way by which it represents something else. Unlike critical epistemology, which remains self-evide...
To be successful in the competitive nano-semiconductor industry, the need to reduce cost per die is necessary and always challenging. Such defect data consist of systematic and random defects that may be yield limiting or may be just cosmetic issue with low probability of yield impact. Nano semiconductor process manufacturing defects can often impact product yields, depending upon the type, siz...
Back cover image: Carbon-based composite electrocatalysts doped with transition metals and heteroatoms are expected to replace noble metal-based catalysts as high-efficiency for OER ORR. In the article number 10.1002/cey2.317, Zhang et al. prepare an ultralong N,S co-doped carbon nano-hollow-sphere chain encapsulated Co nanoparticles, analyze its growth mechanism catalytic activity ORR/OER, pro...
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-...
With nanotechnology becoming widely used, many applications such as plasmonics, sensors, storage devices, solar cells, nano-filtration and artificial kidneys require the structures with large areas of uniform periodic nanopatterns. Most of the current nano-manufacturing techniques, including photolithography, electron-beam lithography, and focal ion beam milling, are either slow or expensive to...
