The NEW LSX-Series of Signal Generators from Tabor Electronics
Introducing the new Lucid X-Series of Microwave Signal Generators from Tabor Electronics. The LSX family of signal generators have 8GHz, 20GHz and 40GHz frequency ranges. With phase noise better than -120dBc/Hz at 1GHz, fast and high-resolution frequency switching and +15dBm of standard output power – these instruments have been designed to meet the industries toughest requirements. Built on Tabor’s modular... -
White Paper: Dual-gate FET-based charge sensor enhanced by in-situ electrode decoration in a MEMS organs-on-chip platform
Continuous monitoring of tissue microphysiology is a key enabling feature of the organ-on-chip (OoC) approach for drug screening and disease modeling. Sensing charged species in OoC tissue microenvironments is thereby essential. However, the inherently small (i.e., cm) size of OoC devices poses the challenging requirement to integrate miniaturized and highly sensitive in situ charge sensing components to maximize signal extraction... -
White Paper: Tunable photoluminescence and SERS behaviour of additively manufactured Au nanoparticle patterns
The ability to tune the localised surface plasmon resonance (LSPR) behaviour of metal nanostructures has great importance for many optical sensor applications such as metal (plasmon) enhanced fluorescence spectroscopy and surface-enhanced Raman scattering (SERS). In this paper, we used Aerosol Direct Writing (ADW) to selectively deposit fine gold nanoparticles (AuNPs) patterns. A low-temperature thermal post-treatment (below 200 °C) provides enough... -
White Paper: High step coverage interconnects by printed nanoparticles
The growing diversity in the used materials in semiconductor packaging provides challenges for achieving good interconnection. Particularly the very soft substrates, such as paper and polymers, and very hard, such as silicon carbide, offer unique challenges to wire-bonding or formation of vertical interconnects. Complementary technologies are therefore needed. Here, a method to direct-write metal tracks on the top and sides... -
White Paper: Boosting the thermoelectric properties of PEDOT:PSS via low-impact deposition of tin oxide nanoparticles
Poly(3,4-ethylenedioxy thiophene):poly(styrenesulfonate) (PEDOT:PSS) exhibits valuable characteristics concerning stability, green-processing, flexibility, high electrical conductivity, and ease of property modulation, qualifying it as one of the most promising p-type organic conductors for thermoelectric (TE) applications. While blending with inorganic counterparts is considered a good strategy to further improve polymeric TE properties, only a few attempts succeed so far due to inhomogeneous embedding... -
White Paper: Dynamic restructuring of supported metal nanoparticles and its implications for structure insensitive catalysis
Some fundamental concepts of catalysis are not fully explained but are of paramount importance for the development of improved catalysts. An example is the concept of structure-insensitive reactions, where surface-normalized activity does not change with catalyst metal particle size. Here we explore this concept and its relation to surface reconstruction on a set of silica-supported Ni metal nanoparticles (mean particle... -
White Paper: Enhancement of room temperature Ethanol sensing by optimizing the density of vertically aligned carbon nanofibers decorated with gold nanoparticles
An ethanol gas sensor based on carbon nanofibers (CNFs) with various densities and nanoparticle functionalization was investigated. The CNFs were grown by means of a Plasma-Enhanced Chemical Vapor Deposition (PECVD), and the synthesis conditions were varied to obtain different number of fibers per unit area. The devices with a larger density of CNFs lead to higher responses, with a maximal... -
White Paper: Mass and density determination of porous nanoparticle films using a quartz crystal microbalance
A method is presented to directly measure the mass output of an impaction printer coupled with a spark ablation generator. It is based on a quartz crystal microbalance and shown to be reliable in quantifying mass deposition rate. Here, the method is demonstrated with an Au nanoparticle aerosol synthesized under several spark ablation and deposition settings. Changes in the deposition... -
White Paper: Aerosol based fabrication of Thiol-capped gold nanoparticles and their application for gene transfection
In this study, an ambient–spark–produced–Au– nanoparticle–laden nitrogen gas was mixed with an atomized solution of 1–hexanethiol and ethanol (EtOH). By increasing the thiol concentration from 0.1% to 1.0% (v/v), the size distribution of merged particles (Au–thiol) was changed from bimodal to unimodal configuration. The latter phenomenon is attributed to quantitative incorporation of Au nanoparticles into atomized particles. Measurements of cell...
