“…On the other hand, the CNTs-modified WE show a typical structure as a network of tubes on the surface of WE. Such structure confirms that the CNTs network is formed on the WE surface and attached to the CNPs layer (van de Burgt, 2014). The appeared connected tubes can enhance the conductivity of the printed sensor (Menon et al , 2017).…”

Purpose Ascorbic acid (AA) is an essential vitamin for human health. Therefore, fast and cost-effective detecting of AA is essential, whether in human or food samples. The purpose of this paper is to develop an electrochemical nanosensor for AA detection. Design/methodology/approach The proposed nanosensor was developed by printing carbon nanoparticles ink and silver nanoparticles ink on a polydimethylsiloxane (PDMS) substrate. The surface of the PDMS substrate was first treated by corona plasma. Then, the nanomaterials printer was used to deposit both inks on the substrate. The working electrode surface was modified by drop-casting of carbon nanotubes. Morphological evaluation was applied using scanning electron microscopy and cyclic voltammetry. Also, a potentiostat was used to detect AA by differential pulse voltammetry. Findings It has been shown that the developed nanosensor linearly worked at a range of (0–5 mM), with a limit of detection lower than 0.8 mM and a relative standard deviation of 6.6%. Originality/value The developed nanosensor is characterized by a simple and cost-effective sensing tool for AA. In particular, the nanomaterials enhanced the nanosensor’s sensitivity due to the high catalytic activity.

“…Raman thermometry can even measure Raman scattering in laser assisted nanostructures even though the parts are smaller than the incident laser spot. It can detect the chemical process of precursors and measure their temperatures in laser-assisted manufacturing, such as laser-assisted chemical vapor deposition and additive manufacturing [64,65], to better monitor the manufacturing process and optimize the structure.…”

Laser-assisted manufacturing (LAM) is a technique that performs machining of materials using a laser heating process. During the process, temperatures can rise above over 2000 °C. As a result, it is crucial to explore the thermal behavior of materials under such high temperatures to understand the physics behind LAM and provide feedback for manufacturing optimization. Raman spectroscopy, which is widely used for structure characterization, can provide a novel way to measure temperature during LAM. In this review, we discuss the mechanism of Raman-based temperature probing, its calibration, and sources of uncertainty/error, and how to control them. We critically review the Raman-based temperature measurement considering the spatial resolution under near-field optical heating and surface structure-induced asymmetries. As another critical aspect of Raman-based temperature measurement, temporal resolution is also reviewed to cover various ways of realizing ultrafast thermal probing. We conclude with a detailed outlook on Raman-based temperature probing in LAM and issues that need special attention.

This chapter describes the work principle, classification, and applications of the temperature sensing technologies used in laser micro/nanofabrication processes. These measurement techniques include contacting thermocouples, and noncontacting pyrometers, infrared thermal imaging, Langmuir probes, and thermoreflectance thermal imaging to monitor surface temperatures and electron temperatures in the plasma plume during laser processing. Factors to be considered for the selection of temperature sensing techniques, including temperature measurement range, resolution, measurement position, and accessibility, are discussed.
