Template – assisted sol – gel approach to synthesize new perspective alumina based catalysts

Vinogradov A.V., Vinogradov V.V., Vinogradov A.V., Vinogradov V.V., Agafonov A.V., Institute of Solution Chemistry of Russian Academy of Sciences, RU

In this work, high stable mesoporous γ-aluminas with different pore structure were synthesized. New kinds of templates were adapted to prepare alumina based catalysts with uniform and bimodal mesopore distribution with ‘small’ and ‘large’ mesopores. [...]

Fabrication of size-tunable gold nanoparticles using plasmid DNA as a biomolecular reactor

Samson J., Piscopo I., Yampolsky A., Nahirney P., Parpas A., Toschi A., Drain C.M., Hunter College of CUNY, US

Plasmid DNA has proven to be a successful template/mold for the formation of metallic nanoparticles because it is readily available, inexpensive, and malleable i.e. it can exist in different topologies. Using different plasmid DNA species [...]

Temperature and Stress Controlled Surface Manipulation in NiAl Nano-Layers

Sutrakar V.K., Roy Mahapatra D., Melnik R.V.N., Indian Institute of Science, IN

Quantum dot arrays with precisely controlled positions and sizes are desirable for making templates for micro-and nano-electronic devices. Numerous experimental works have shown that unguided self-assembled growth of quantum dots usually fails to realize perfectly [...]

Templated virus deposition: from molecular-scale force measurements to kinetic Monte Carlo simulations

Elhadj S., Gilmer G.H., Friddle R.W., Estrada M., Manchester M.E., Johnson J.E., De Yoreo J.J., Noy A., Lawrence Livermore National Laboratory, US

The use of macromolecular scaffolds for hierarchical organization of molecules and materials is a common strategy in living systems that leads to emergent behavior. One characteristic of this strategy is that it generates micron-scale structures [...]

Growth and Engineering of High Aspect-Ratio AAO Templates Integrated on Silicon Substrates

Choi S., Daugherty M., Enable IPC Corporation, US

We have developed a CMOS-compatible process for manufacturing nanowires directly on silicon (or other) substrates. This process removes some of the steps for conventional nanowire manufacture. The result are highly-ordered, high aspect-ratio nanowires for use [...]

Nanoimprint Mold Manufacturing with Focused Ion Beam

Chung M., Huang B.R., Weng M.H., Fu C.S., Chang Y.Y., Lai S.W., Chiou J.M., Chen Y-C, Tzeng Y.H., Southern Taiwan University of Technology, TW

Nanoimprint lithography (NIL) is an emerging low cost technique for reproducing sub-100 nm pattern in various applications; however, manufacturing the mold for nanoimprint has been a key issue both in expense and resolution. Focused Ion [...]

Protein can act as unique template to assemble gold nanoparticles in a linear fashion

Bhattacharya R., Patra C.R., Wang S., Lu L., Yaszemski M.J., Mukhopadhyay D., Mukherjee P., Mayo Clinic, US

Nanoparticles of metals possess unique chemical, electronic, optical and magnetic properties from their bulk counterpart because of the quantum size effects. The spatial orientation and arrangement of nanoparticles is important in the realization of technologically [...]

Anodisation of Thin Film Aluminium

Douglas C, Evans P, Pollard R.J., Queen's University, Belfast & Nanotec NI, UK

Anodisation of alumina is a promising route for the preparation of nano-templates where regular arrays of pores can be produced in foils using a two step anodisation process [1] and Figure 1. The integration of [...]
