Scanning Techniques of Laser Surface Texturing
Laser surface texturing (LST) is one of the most promising technologies for controllable surface structuring and the acquisition of specific physical surface properties needed in functional surfaces. The quality and processing rate of the laser surface texturing strongly depend on the correct choice of a scanning strategy.

Augmented Reality for Surgical Robotic and Autonomous Systems
Novel surgical robots are the most sought-after approach in performing repetitive tasks in an accurate manner. Imaging technology has significantly changed the world of robotic surgery, especially when it comes to biopsies, the examination of complex vasculature for catheterization, and the visual estimation of target points for port placement. There is a great need for the image analysis of CT scans and X-rays for the identification of the correct position of an anatomical landmark such as a tumor or polyp. This information is at the core of most augmented reality systems, where development starts with the reconstruction and localization of targets. Hence, the primary role of augmented reality (AR) applications in surgery would be to visualize and guide a user towards a desired robot configuration with the help of intelligent computer vision algorithms.

Electric Vehicle Travel by Considering Preferences of Users
The dual-carbon strategy advocates a green, environmentally friendly, and low-carbon lifestyle. In the field of transportation, electric vehicles (EVs) have been regarded as an effective solution to reduce carbon emissions and to conserve energy. Developing a reasonable charging guidance scheme for users is a feasible way to solve problems, such as the range anxiety of EV users, and has a great application value for the promotion of EVs in the future. In the whole travel charging process, the preference habits of EV users directly affect their choice of charging stations. Therefore, it is necessary to consider users’ preferences in charging guidance strategies.

Design Parameters of Power Amplifiers for Ultrasound Applications
A design analysis of the power amplifiers developed for ultrasound applications was conducted because ultrasound applications require different types of power amplifiers, which are one of the most critical electronic components in ultrasound systems. To generate acoustic signals using transducers, which are among the most important mechanical devices in ultrasound systems, an appropriate output voltage, current, or power signal must be produced by a power amplifier.

Electrolyte Additives in Vanadium Redox Flow Batteries
Vanadium redox flow batteries (VRFBs) are promising candidates for large-scale energy storage, and the electrolyte plays a critical role in chemical–electrical energy conversion. However, the operating temperature of VRFBs is limited to 10–40 °C because of the stability of the electrolyte. To overcome this, various chemical species are added, but the progress and mechanism have not been summarized and discussed yet.

6G Technology in Mobile-Health Multimedia
Mobile-health (m-health) is described as the application of medical sensors and mobile computing to the healthcare provision. While 5G networks can support a variety of m-health services, applications such as telesurgery, holographic communications, and augmented/virtual reality are already emphasizing their limitations. These limitations apply to both the Quality of Service (QoS) and the Quality of Experience (QoE). However, 6G mobile networks are predicted to proliferate in order to solve these limitations, enabling high QoS and QoE.

Electromagnetic Fields Exposure
In different situations, electromagnetic fields (EMF) are consumed every day in several sociable purposes. Additionally, they are employed securely in medical treatments. Conversely, when these fields are operated inadvertently, it can crop unfavorable outcomes. These consequences are intimately linked to the type of the EMF and the exposed substance. The strength of the field as well as its frequency typify EMF, whereas the physical and geometric properties describe matter.

Applications of Smart Drug Delivery Devices
The internet of things (IoT) plays a vital role in smart drug delivery systems. It is an emerging field that offers promising solutions for improving the efficacy, safety, and patient compliance of drug therapies. IoT-based drug delivery systems leverage advanced devices, sophisticated sensors, and smart tools to monitor and analyse the health matrices of the patient in real-time, allowing for personalised and targeted drug delivery. This technology is implemented through various types of devices, including wearable and implantable devices such as infusion pumps, smart pens, inhalers, and auto-injectors. However, the development and implementation of IoT-based drug delivery systems pose several challenges, such as ensuring data security and privacy, regulatory compliance, compatibility, and reliability.

Surface-Enhanced Raman Spectroscopy Substrates for Food Safety Detection
Food safety analysis currently relies on the enzyme-linked immunosorbent assay (ELISA), polymerase chain reaction (PCR), high-performance liquid chromatography (HPLC), gas chromatography (GC), UV-visible spectrophotometry, and tandem mass spectrometry (MS), all of which require significant time to train qualified food safety testing laboratory operators. These factors have hindered the development of rapid food safety monitoring systems, especially in remote areas or areas with a relative lack of testing resources. Surface-enhanced Raman spectroscopy (SERS) has emerged as one of the tools of choice for food safety testing that can overcome these dilemmas. SERS offers advantages over chromatographic mass spectrometry analysis due to its portability, non-destructive nature, and lower cost implications. However, as it currently stands, Raman spectroscopy is a supplemental tool in chemical analysis, reinforcing and enhancing the completeness and coverage of the food safety analysis system. SERS combines portability with non-destructive and cheaper detection costs to gain an advantage over chromatographic mass spectrometry analysis.
