Fabrication of nanomaterials using porous alumina templates
Nanofabrication by self-organization methods has attracted much attention owing to the fact that it enables mass production without the use of expensive lithographical tools, such as an electron beam exposure system. Porous alumina can be fabricated electrochemically through anodic oxidation of aluminum by means of such a self-organization method, yielding highly ordered arrays of nanoholes sev...
متن کاملLaboratory assessment of the mobility of nanomaterials in porous media.
The production of significant quantities of engineered nanomaterials will inevitably result in the introduction of these materials to the environment. Mobility in a well-defined porous medium was evaluated for eight particulate products of nanochemistry to assess their potential for migration in porous media such as groundwater aquifers and water treatment plant filters. Contrary to the asserti...
متن کاملDirect imprinting of porous substrates: a rapid and low-cost approach for patterning porous nanomaterials.
This work describes a technique for one-step, direct patterning of porous nanomaterials, including insulators, semiconductors, and metals without the need for intermediate polymer processing or dry etching steps. Our process, which we call "direct imprinting of porous substrates (DIPS)", utilizes reusable stamps with micro- and nanoscale features that are applied directly to a porous material t...
متن کاملPorous Nanomaterials for Ultrabroadband Omnidirectional Anti-Reflection Surfaces with Applications in High Concentration Photovoltaics
John A. Rogers, and co-workers demonstrate broadband anti-reflection coatings that rely on porous nanomaterials formed by selfassembly. The image shows the use of such coatings (orange) on an array of lenses within a concentration photovoltaics architecture, where photons are efficiently concentrated onto underlying triple-junction solar cells, leading to an efficiency enhancement of ≈8%. POROU...
متن کاملAn Eco‐Friendly, Tunable and Scalable Method for Producing Porous Functional Nanomaterials Designed Using Molecular Interactions
Despite significant improvements in the synthesis of templated silica materials, post-synthesis purification remains highly expensive and renders the materials industrially unviable. In this study this issue is addressed for porous bioinspired silica by developing a rapid room-temperature solution method for complete extraction of organic additives. Using elemental analysis and N2 and CO2 adsor...
