The optical response of non-spherical gold nanoparticles not only depends on the size of the objects, but also on their shape and orientation with respect to the polarization direction of the light, exciting the plasmon resonance. This study demonstrates a method to grow non-spherical gold nanoparticles via organometallic chemical vapor deposition (OMCVD) onto planar substrates that are covered by SH-terminated self-assembled monolayers (SAMs). Trimethylphosphinegoldmethyl ((CH3)3PAuCH3) is used as the volatile organic precursor. The shape of the deposited particles varies with respect to the nature of the template SAM: disc-like and pancake shaped nanoparticles are fabricated with different aspect rations between the two main axes. UV–vis, AFM, STM, SEM and evanescent waveguide absorption spectroscopy (EWAS) of the OMCVD gold nanoparticles are applied to determine and verify the dimensions and orientation of the nanoparticles in two dimensions. When clusters of nanoparticles are formed, an additional plasmon band with a large red-shift is observed. [less ▲]

Three different rapid manufacturing methods for the construction of fluoropolymer microfluidic devices were investigated: (1) fluoropolymer/epoxy laminate/fluoropolymer structures, (2) fluoropolymer/fluoropolymer structures and (3) fluoropolymer/epoxy laminate/glass structures. The structures are chemically and physically robust and the fluoropolymer constructs can be used for optical wave guiding. Principles behind the use of fluoropolymer waveguide constructs and a basic theoretical analysis of the improvements they offer are presented. The otherwise problematic bonding of the polymers was facilitated by chemical (sodium naphthalene) surface treatment. The effects of the process were characterized by contact angle and bond strength measurements. For demonstration purposes, microfluidic channels were fabricated using Ordyl SY epoxy laminate (methods 1 and 3) and hot embossing of the polymers (method 2). The first method (fluoropolymer/epoxy laminate/fluoropolymer) proved to be the most reliable and successful, in particular when bonding the various layers. [less ▲]

Ultracold atoms can be manipulated using microfabricated devices known as atom chips. These have significant potential for applications in sensing, metrology, and quantum information processing. To date, the chips are loaded by transfer of atoms from an external macroscopic magnetooptical trap (MOT) into microscopic traps on the chip. This transfer involves a series of steps, which complicate the experimental procedure and lead to atom losses. In this paper, we present a design for integrating a MOT into a silicon wafer by combining a concave pyramidal mirror with a square wire loop. We describe how an array of such traps has been fabricated, and we present magnetic, thermal, and optical properties of the chip. [less ▲]

A novel process for the fabrication of a microelectromechanical systems (MEMS) metallic component with features smaller than 10 µm and high thermal conductivity was investigated. This may be applied to new or improved microscale components, such as (micro-) heat exchangers. In the first stage of processing, equal channel angular pressing (ECAP) was employed to refine the grain size of commercial purity aluminium (Al-1050) to the ultrafine-grained (UFG) material. Embossing was conducted using a micro silicon mould fabricated by deep reactive ion etching (DRIE). Both cold embossing and hot embossing were performed on the coarse-grained and UFG Al-1050. Cold embossing on UFG Al-1050 led to a partially transferred pattern from the micro silicon mould and high failure rate of the mould. Hot embossing on UFG Al-1050 provided a smooth embossed surface with a fully transferred pattern and a low failure rate of the mould, while hot embossing on the coarse-grained Al-1050 resulted in a rougher surface with shear bands.

Le Moabi (Baillonella toxisperma) est protégé par le Gouvernement gabonais depuis 2009. C’est un arbre à usages multiples qui a une importance culturelle et historique pour les communautés rurales, qui entretiennent une relation étroite avec ce géant de la forêt. Comme ses cousins le Karité en Afrique de l’Ouest ou l’Arganier en Afrique du Nord (famille des sapotacées), les graines de Moabi permettent de produire une huile de grande valeur possédant des vertus alimentaires, cosmétiques et médicinales.
