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...

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...

Spark ablation in gas (SAG) technology has the characteristics of being green, fast quenching, fast dynamics and specializes in producing metallic nanoparticles with a clean surface, small size, and abundant defects. In this study, Ag nanoparticles were prepared via SAG and in situ loaded on a carbon fibre through nitrogen flow. The effect of the carrier gas flow rate and...

BackgroundRADAR (“Radio Detection And Ranging”) is a system that uses electromagnetic waves to identify an object, its direction, relative speed, or even for 2D & 3D imaging. Radars help identify both fixed & moving objects such as aircraft, ships, vehicles, weather formations, and terrain. Radars use transmitters that emit electromagnetic waves that are reflected by a target (“Echoes”) and detected...

Electromagnetic Radiation, RF Pulses and RadarA radar transmitter generates multiple forms of electromagnetic energy. This energy is amplified and transmitted and ultimately is reflected off a target, received and the difference in time and frequency of the transmit signal verses the received signal is used to determine the distance and velocity of a target.Referring to figure 1; a pulse of...

Authors: James Skinner & Nick Ridler, National Physical LaboratoryNils Nazoa, LA Techniques LtdMark Ashcroft, Pico Technology AbstractThese days, many instrument calibrations are performed automatically – for example, using electronic calibration units. This includes calibration of vector network analysers (VNAs) where the calibration standards are generated electronically rather than using mechanical devices. However, verifying performance – particularly accuracy – of these...

This document describes how to implement a Radar Target Simulator/Generator using the Tabor Electronics’ Proteus AWT (Arbitrary Waveform Transceiver). The Proteus AWT RTS system is a configuration of the Proteus AWT that is design to receives a signal from the Radar under test and performs real time calculations in its internal FPGA to simulate a moving target. High level FPGA...

The new Research Center MAIN of TU Chemnitz in Germany recently added a cleanroom to their Optics/Plasmonics laboratory. The lab required a large optical table surface installed in the cleanroom’s raised floor environment, a somewhat unusual setup. Click here to see how TMC solved this vibration problem.

Aspheric optics are commonly used in advanced optical systems, such as AR/VR headsets, surveillance systems and semiconductor applications, to minimize size, weight, and cost. Achieving the required level of performance requires stringent control in the machining and metrology of the optics. One of the manufacturing tools used to make precision aspheres is a single point diamond turning lathe like those...
