Crop cultivar identification is fundamental for agricultural research, industry and policies. This paper investigates the feasibility of using visible/near infrared hyperspectral data collected with a miniaturized NIR spectrometer to identify cultivars of barley, chickpea and sorghum in the context of Ethiopia. A total of 2650 grains of barley, chickpea and sorghum cultivars were scanned using ...

The online and accurate monitoring of drinking water supply networks is critically in demand to rapidly detect the accidental or deliberate contamination of drinking water. At present, miniaturized water quality monitoring sensors developed in the laboratories are usually tested under ambient pressure and steady-state flow conditions; however, in Water Distribution Systems (WDS), both the press...

In this paper we discuss the fabrication and characterization of miniaturized triglyceride biosensors on crystalline silicon and porous silicon (PS) substrates. The sensors are miniaturized Electrolyte Insulator Semiconductor Capacitors (mini-EISCAPs), which primarily sense the pH variation of the electrolyte used. The lipase enzyme, which catalyses the hydrolysis of triglycerides, was immobili...

A miniaturized biotelemetric device for the amperometric detection of brain tissue oxygen is presented. The new system, derived from a previous design, has been coupled with a carbon microsensor for the real-time detection of dissolved O(2) in the striatum of freely moving rats. The implantable device consists of a single-supply sensor driver, a current-to-voltage converter, a microcontroller, ...

For DNA purification to be functionally integrated into the microchip for high-throughput DNA analysis, a miniaturized purification process must be developed that can be easily adapted to the microchip format. In this study, we evaluate the effectiveness of a variety of silica resins for miniaturized DNA purification and gauge the potential usefulness for on-chip solid-phase extraction. A micro...

Miniaturization is rapidly growing, with novel ideas emerging in recent years. Like other fields, analytical systems have been affected by this new technology. Concretely, the capacity to carry out laboratory operations on a small scale using miniaturized devices is very appealing. Micro total analysis systems (mTAS), also called lab-on-a-chip, have renewed interest in scaling laws in the last ...

A S-band miniaturized circularly polarized microstrip antenna is designed and fabricated. The curved current technique utilized, the effective path length of increased by loading U-shaped slot on radiating patch. Thus resonant frequency can be tuned significantly miniaturized. experimental samples are fabricated tested. measured results show that two frequencies 2.17GHz 2.25GHz, with an impedan...

Miniaturized manipulation and control of surface plasmon waves have long been a desirable goal. However, conventional nanomethods high losses uncontrollable outcomes, which limit their utility in light–matter interaction. To overcome these challenges, method for achieving directional propagation concentration using nanostructures is proposed. By focusing the transmission on tip nanotriangle, po...
