Using a porous nickel molybdate nanosheets–chitosan nanocomposite-modified glassy carbon electrode, Lou et al. [68] created an electrochemical sensor for amlodipine detection. When compared to some of the electrochemical sensors created for the determination of amlodipine, such as multiwalled carbon nanotube sensors and graphite-modified paste electrodes, this device displays enhanced electrochemical performance. A sensor based on chitosan–zeolitic imidazolate framework-8 (ZIF-8)–acetylene black nanocomposites for rutin measurement had a similar case [69]. ZIF-8 and acetylene black were dispersed with the help of chitosan. The dispersion was then put over the glassy carbon electrode’s surface and cured under an infrared lamp. The sensor had exceptional sensitivity, stability, and repeatability when it comes to rutin, according to the authors.
Fabrication and Characterization Methods

Prior to every annealing cycle, existing gases inside the anneal chamber and gas lines were flowed with high-grade pure N2 (99.99995%), followed by pumping and purging to minimize the possibility of contamination by other existing gases or particles. This RTA system is heated up by an infrared lamp heating furnace. The gas flow rate is kept at 250sccm (standard cubic centimeters per minute) for annealing cycles. A two-inch Si (100) wafer is used as a sample holder. All annealed samples are removed from the chamber at below 80°C. Figure 2.4 shows a typical (600oC as a target temperature) program for annealing treatment in this RTA system.

This meter consists of a balance and an infrared lamp. The pan of the balance is counter-balanced by a fixed and an adjustable weight along a lever. There is also a scale calibrated in moisture content. The infrared lamp is mounted on a swiveling arm above the pan.

The GCE was sequentially polished with 1.0, 0.3 and 0.05 µm alumina slurry on velvet. The residual alumina slurry was rinsed off with distilled water, and the GCE was placed in anhydrous ethanol and distilled water with ultrasonication (60 kHz, 55 °C) for 10 min. The cleaned GCE was dried with an infrared lamp. The humic acid (10 mg) and Nafion solution (10 µl) were dispersed in 10 ml anhydrous ethanol with ultrasonication (60 kHz, 55 °C) for 30 min to obtain a homogenous suspension. The humic acid (500 mg) and metal solutions (0.1 M, 10 mL) were mixed with ultrasonication (60 kHz, 55 °C) for 10 min and left for 24 h. Humic acid-metal precipitates were washed with a double distilled water and dried over P2O5 in a vacuum desiccator or in an oven at a temperature of 60–80 °C to a constant weight.

A 50-μl solution equivalent to about 950 Bq was pipetted with a glass capillary from the 237Np standard solution, and then dropped onto a glass microfiber filter with a size of 4 × 4 mm and a thickness of 260 μm. The glass microfiber filter was dried and solidified with an infrared lamp. After drying, the glass microfiber filter impregnated with the 237Np sample was wrapped with a fluoropolymer film (FEP). Nuclides 59Co and 197Au with well-known cross-section data were selected firstly as neutron flux monitors. In order to confirm in Westcott’s convention [38] whether or not an irradiation field is well thermalized, multiple monitors with different sensitivities to epi-thermal neutrons were used such as scandium-45, cobalt-59, molybdenum-98, tantalium-181 and gold-197. The amount of flux monitors was determined by their content ratios and weight measurements with the model XP6 microbalance (Mettler Toledo, United States). Table 1 summarized information on sample weight, size, and shape. Figure 6 shows an outline of the irradiation targets, where the neutron flux monitors are arranged around the 237Np sample so as not to interfere with each other. The outline of the prepared irradiation capsule is also shown in Figure 6. A cushioning material (absorbent cotton) was packed in a polyethylene capsule. The target consisting of the 237Np sample and flux monitors was set on the upper edge in the capsule so that the target was exposed in a well-thermalized neutron field in the graphite thermal column.

SARChess’s hardware includes a projector, a camera with an infrared filter, a computer, an infrared lamp, and a projection tabletop. To allow players to interact with the hardware and virtual objects in an intuitive interaction, Norman’s design principles are considered in the interaction design for SARChess, and chess identification, coordinate mapping, movement detection, and movement legality check algorithms are integrated into SARChess. The software modules are constructed based on hardware setup, interaction design, and algorithms. The architecture of SARChess is shown in Figure 1.
