This review focuses and summarizes recent studies on the functionalization of carbon nanotubes oriented perpendicularly to their substrate, so-called vertically aligned carbon nanotubes (VA-CNTs). The intrinsic properties of individual nanotubes make the VA-CNTs ideal candidates for integration in a wide range of devices, and many potential applications have been envisaged. These applications c...
این پژوهش به اکسید اسیون متانول در محیط قلیایی می پردازد. برای این منظور ابتدا ترسیب ذرات نیکل، پلاتین و نیکل – پلاتین بر روی زیر لایه کاغذ کربنی به روش آبکاری به شیوه ی جریان مستقیم استفاده شد. در ادامه مورفولوژی پوشش های ذرات فلزی بر روی کاغذ کربنی از طریق میکروسکوپ الکترونی روبشی بررسی و مطالعه شد. سپس خواص کاتالیستی الکترودها ی حاصل در اکسیداسیون متانول با استفاده از روشهای الکتروشیمیایی هم...
Methyl(trifluoromethyl)dioxirane (TFDO) can be used for the oxyfunctionalization of SWCNTs filled with NaI and LuCl₃ under mild conditions. The chosen metal halides are of interest for theranostics, both for imaging and therapy when in their radioactive form. The applied functionalization methodology does not require metal catalyst, preserves the integrity of the nanotubes during treatment, avo...
Previous studies have suggested several adaptive functions for the decorated tube caps of Diopatra cuprea (Polychaeta: Onuphidae). We experimentally tested the hypothesis that decoration provides crypsis. A series of field experiments quantified predation-related damage done to tube caps that were (1) devoid of decoration, (2) decorated with algae, or (3) decorated with shell fragments. If deco...
As renewable energy is becoming a critical source to meet the global demand, electrochemical storage devices become indispensable for efficient and reliable supply. The electrode material key factor determining capacity power delivery of devices. Carbon-based materials are emerging as viable candidate electrodes, yet their low densities impede development advanced materials. Nanoparticle decora...
