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 [...]

A plasma electrochemistry reactor enabling the rapid and continuous-flow synthesis of gold and platinum group metal (PGM) nanoparticles

Fortin M.-A., Bouchard M., Turgeon A., Université Laval, CA

Abstract: Platinum group metals (PGM: Pd, Pt, Ir, Rh, etc) are commonly used in catalysis. Conventional catalysts typically consist of PGM nanoparticles dispersed on high surface area oxide supports.[1] However, high PGM loadings must be [...]

Effect of β-Silicon Carbide Size and Shape on the Properties and Microstructure of PMMA Matrix Nanocomposites

Watt M.R., Gerhardt Ro.A., Georgia Institute of Technology, US

The objective of this research is to fabricate, beginning with screen printing, electrically conductive glass nanocomposite films and optimize their properties. By discovering an optimum thickness and nanoparticle spacing within the glass matrix, we may [...]

Nanocrystals growing under irradiation of electron beam

Huang W-Q, Huang Z-M, Liu S-R, Huang W-Q, Huang Z-M, Dong T-G, Wang G., Qin C-J, Guizhou University, CN

In our experiment, it was observed that silicon nanocrystal rapidly grows with radiation of electron beam on amorphous silicon film prepared by pulsed laser deposition, and shape of silicon nanocrystal is usually sphere in smaller [...]

Stretchable Gas and UV Sensors towards Wearable Electronics

Gutruf P., Walia S., Zeller E., Nili H., Sriram S., Bhaskaran M., RMIT University, AU

Electronics and sensors pervade all aspects of life, needing solutions to make them less obtrusive, which is where fully transparent electronics come into play. Our research focus has been to realise stretchable electronic devices with [...]

Automated Continuous Flow Reactor for the Mass Production of Photoluminescent Nanoparticles

Simsek E., V. Akgun O., Heves E., Dogan L., Hocaoglu I., Dagtepe P., Sezen N., T. Ruzgar H., Kuantag Nanoteknolojiler Gelistirme ve Uretim A. S., TR

Batch and flow reactors are two most common production methods employed widely in various chemical industries. The main advantage of flow reaction systems over batch reactors is the continuous production capability. Besides, particularly for the [...]

Open Droplets: Programming Chemical Flow in Microfluidics

Baret J-C., University of Bordeaux, FR

Droplet-based microfluidics is the key technology for the miniaturization and automation of assays in microcompartments. It relies on the use of emulsion droplets as microreactors each encapsulating a biological system of interest (genes, cells, drugs,...) [...]

Reviving natural product and drug discovery pipelines with fungal artificial chromosome (FAC) technology

Clevenger K., Bok J.W., Ye R., Miley G., Velk T., Chen C., Yang K.H., Gao P., Lamprecht M., Thomas P., Islam M.D., Keller N., Kelleher N., Wu C., Intact Genomics, Inc., US

We have developed the fungal artificial chromosome [FAC, or autonomously replicating E. coli- fungal shuttle bacterial artificial chromosome (BAC)] vector and system. The FAC technology enables unbiased capturing of 263 full-length large secondary metabolite (SM) [...]

nano Droplet Array Plates (nDAPs): 3D Cell Culture in Anchored Hydrogel Droplets Compatible with Conventional Microplates

Xu Q.F., Chen X., Lyons A.M., ARL Designs LLC, US

University researchers as well as large pharmaceutical companies need improved technologies for discovering new drugs. Current drug-discovery approaches are highly inefficient, as

Capillary flow of whole blood in microsystems: non-Newtonian blood behavior and substrate reagent-coating effect

Berthier J., Gosselin D., Huet M., Sabatte G., Cosnier M.L., Pouteau P., Cubizolles M., CEA-Leti (University Grenoble Alpes), FR

Introduction: The use of whole blood is a preferred solution for portable diagnostic and monitoring systems. We analyze here two particularities of microsystems for blood analysis: the blood non-Newtonian behavior, and the capillary flow in [...]
