Two-step approach for the nanofabrication of highly ordered ultra-long porous gold nanowires with an adjustable porosity for SERS-based sensors

Chauvin A., Delacôte C., Molina-Luna L., Boujtita M., Thiry D., Du K., Ding J., Choi C-H, Humbert B., Mevellec J.-Y., Tessier P.-Y., El Mel A.-A., Institut des matériaux Jean Rouxel, FR

Recently, nanoporous gold has been pointed out as a promising candidate for the development of SERS-based sensors for the detection of environmental toxins and small molecules [1]. One way to improve the detection ability of [...]

Uniformly Distributed Metal Nano-particles in Various Sized Porous Catalytic Supports by NPP Process

Lee C., Lee J-H., Lee C., Lee J-H., Kang B.K., Kaji H., Hayashi M., Koh S.K., GL Materials, KR

2~10 nm sized metal nano-particles were uniformly loaded in porous activated carbon (AC) support and 10~100 nm sized metal nano-particles were completely covered on the surfaces of air flow channels of porous ceramic monolith. Metal [...]

Construction and properties of zein-based cell supports and scaffolds

Padua G.W., Wang Q., Wang Y., Wang Q., Wang Y., University of Illinois Urbana-Champaign, US

Zein, a protein abundant in corn, is capable of self-assembly and may form a variety of structural morphologies (Wang et al 2004, Wang et al 2008a). Zein micro-fibers (Figure 1.), films, and sponges (Figure 2) [...]

NanoZeolites – small particles, small pore, big impact! Porous nanoparticles for environmental applications

Daniell W., Kohl A., Sauer J., NanoScape AG, DE

NanoScape has developed hydrothermal synthesis techniques which allow nanocrystalline, porous aluminosilicates (NanoZeolites) to be manufactured, currently on a 100kg p.a. scale. A range of NanoZeolites are available with pore sizes ranging from 3A to 100A. [...]

NanoZeolites – porous nanomaterials for cleantech, encapsulation and triggered release applications

Daniell W., Sauer J., Kohl A., NanoScape AG, DE

Recent advances in hydrothermal synthesis techniques and procedures to modify the surfaces of the particles have led to the development of a new class of material – the NanoZeolites. The availability of porous, nanocrystalline materials [...]

Manufacturable nanoscale membranes – material development and biological separations

Gaborski T.R., Striemer C.C., Snyder J.L., Fang D.Z., Fauchet P.M., McGrath J.L., University of Rochester, US

We have developed a new class of ultrathin porous nanocrystalline silicon (pnc-Si) membranes using inexpensive and scalable silicon fabrication techniques. Pnc-Si is formed from a deposited amorphous silicon thin film, where nanoscale pores are introduced [...]

Porous filter with spatially graded response

Krause K.M., Hawkeye M., Brett M., University of Alberta, CA

Glancing Angle Deposition (GLAD) has become a common technique for producing thin porous films with various structural features. In the current work, we have further modified GLAD in order to create porous structures that have [...]
