“…The alumina wall served well as the catalyst needed for the CNT deposition. [21,22] On the other hand, porous SnO 2 nanotubes could also be formed inside the alumina pores by using an infiltration technique developed perviously. [23] Figures 1a,b display the field-emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) images, respectively, of SnO 2 nanotubes after four loading cycles using a 3 wt.-% commercial The corresponding selected-area electron diffraction (SAED) pattern consists of a few diffraction rings consistent with the rutile structure of tin oxide (see Supporting Information, part 3).…”

The preparation of SnO2 nanotubes with coaxially grown carbon nanotube overlayers with good conformal control of shape and size is reported. The SnO2‐core/carbon‐shell nanotubes (see Figure) are excellent reversible lithium‐ion storage compounds combining the best features of carbon (for cyclability) and SnO2 (for capacity). These structures deliver high specific capacity (∼ 540–600 mA h g–1) and good cyclability (0.0375% capacity loss per cycle).

“…The graphitic order was short-range, as is typical of CNTs grown within the pores of an alumina template without a metal catalyst. [21,22] Elemental analysis showed some low-level residual hydrogen content (H/C weight ratio: 0.5 %). According to Wang et al, [23] catalytic action of the latter.…”

“…Alumina membranes and electrodeposition inside the pores are now being developed due to the possibility of making arrays of carbon nanotubes of controlled length and pore diameter [13,[109][110][111][112][113][114][115][116][117][118][119][120][121][122]. Anodization is an electrochemical process by which nanosized pores self-form in an insulating oxide film of alumina.…”

“…Template synthesis offers a frame for molecular device construction. Alumina membranes are a very widely used template for the growth of carbon nanotubes [109][110][111][112][113][114][115][116][117][118][119][120]147,[186][187][188][189]. Multi-wall carbon nanotubes (MWNT) were grown by a CVD reaction in the porous of alumina for transport measurements, Figure 16 [190].…”

Abstract. We present an overview of template synthesis as it applies to our nanomaterials research. This bottom-up approach is motivated by our desire to find an alternative to the big, top-down approaches to nanoscience, such as clean-rooms and X-ray lithography. Using universally available templates and materials, and very modest synthesis techniques, we have created a variety of interesting and useful structures. Starting with homogeneous ferromagnetic nanowires, we were able to study and manipulate spin-dependent transport. Next, we branched into multi-layer GMR and spin-valve structures for spintronics. As a side trip, we put carbon-encapsulated fullerene nanoparticles into nanopores for ballistic magnetoresistance studies. Carbon nanotube molecules were grown in templates by CVD self assembly. The carbon nanotubes grown using a cobalt catalyzer show spin-valve, ballistic transport, and Coulomb blockade effects. Very recently, we have started to study templated semiconductor nanorods with the amazing result that their behaviour is very similar to that of the carbon nanotubes and can be reduced to a scaling law. Essentially, the template acts as a skeleton for the nanoscale synthesis and macroscale contact of an infinite variety of materials and structures. It is our hope that by the following examples we demonstrate that high quality nanoscience research is available to everybody. PACS

“…The fabrication of FePt:C nanocomposites consists of the synthesis of FePt clusters at low temperature and the introduction of carbon by CVD [15]. After the synthesis of FePt clusters at 650°C for 1 hr, the flowing hydrogen was switched to high-purity nitrogen containing 3 vol % C 2 H 2 at the same temperature for 30 min for the deposition of carbon.…”

Magnetic nanostructures with desirable properties such as monodispersed size and crystallographic texturing can be fabricated by a number of synthetic techniques. In this paper, we discuss methods for creating nanoclusters with fine control of individual propertiesand their interactions, as well as a promising chemical technique that provides control of several properties simultaneously. Current and potential applications also will be addressed.
