In Electric Arc Furnace (EAF) steelmaking, the push for improved efficiency requires accurate analysis of the chemical composition of its slag system to control slag foaming, provide refractory protection, and maintain high furnace iron yield. Therefore, the ability to obtain real-time slag chemistry data would provide a useful tool to improve the control and efficiency of the process. The work reported here aims to assess the structure and chemistry of EAF slags at high temperatures using a portable fiber-optic Raman probe. The ability to relate Raman spectra peaks to chemistry and structure is demonstrated in experimental result with EAF slags at 1550°C. © 2023 by the Association for Iron & Steel Technology.

This paper reports a method of frequency scaling millimeter wave thin-film lithium niobate (LiNbO3) acoustic resonators using ion beam assisted Argon gas cluster trimming whilst maintaining a high figure of merit (FoM) and averting ultra-thin-film fabrication difficulties. A transferred 100 nm thick 128° Y-cut LiNbO3 thin film is trimmed to a thickness of 75 nm. Consequently, a 24.4 GHz first-order antisymmetric mode (A1) resonator with a high k2 of 34.3%, a Q of 54, and an FoM of 18.5 is presented. The quality of the film was maintained during the trimming process, proven by material-level analysis, and exhibited a similar f•Q product compared with resonators fabricated using the original film. These results show a viable and less complex path toward further frequency scaling acoustic devices. © 2023 IEEE.

Metal halide perovskites (MHPs) possess advantageous optoelectronic properties, so perovskite emitters and perovskite light-emitting diodes (PeLEDs) are promising candidates for next-generation high-colour-purity displays and lighting applications. Within the past 5 years, the luminescence efficiency of MHP emitters and PeLEDs has increased rapidly. However, the industrial applications of perovskites are impeded by several technical bottlenecks, such as insufficient colour reproducibility, low operational stability, toxicity and limited large-scale production. In this Review, we survey the current status of MHP emitters and PeLEDs and provide a technical roadmap to highlight the goals and requirements for them to successfully enter the markets for vivid displays with high colour purity, augmented and virtual reality displays and general and special lighting. We also set out steps for future research in MHPs and their device applications.

Reliability testing of electronic devices is vital;anything from temperature and humidity resistance to mechanical fatigue of materials needs to be tested to ensure devices can hold up to their needed life expectancy - particularly in the field of biosensors and flexible conductors. Unfortunately, the research for specific techniques can be scarce, and often devices need to be tested in their own unique way. In this work, we have developed an automated system for reliability testing of strain-dependent sensors through the cyclic bending of a polyimide substrate with a conductive graphene film. A device was created using a 180-degree servo motor in combination with an Arduino microcontroller. The servo motor was then paired with a rack and pinion gear set to function as a linear actuator and bound to an independently built sliding mechanism that serves as the control and measurement of repeated bending operations. The substrate with the graphene film was then attached to a source meter to measure the current flow in situ over time. Subsequently, this device was able to repeat multiple bend cycles identically, eliminating the need to do it by hand and creating uniformity toward data gathering for comparative experimental studies. As such, the automated cycling system fulfilled its purpose towards a reliability test for which the graphene film showed the ability to withstand fatigue through repeated loading. © 2024 IEEE.

More than 1.3 million electric vehicles have been installed throughout the globe, and public charging networks for these vehicles are becoming increasingly common. It has been an area of interest to establish a plan for prioritizing the charging of electric vehicles (EVs) from a single network. This is particularly important in situations when the power source is restricted, such as with renewable energy, and for economic reasons (a higher price per KWh for quicker charging). When used in conjunction with electric vehicle (EV) charging, solar energy significantly decreases our reliance on fossil fuels. An electric car solar charger is created and constructed inside this system. In order to maximize the output from the solar panels, a dc-dc boost converter is used to transfer the voltage from the panels to the station's batteries. Maximum Power Point Tracking (MPPT) is also included. Power the charging station with energy from the solar panels so that the vehicle's rechargeable battery may be charged. The charging station's status can be monitored at any time via the Internet of Things. We have created a solar-powered charging station to provide simple accessibility. Solar power is both a sustainable and accessible renewable energy source. Arduino controller for light-dependent resistor (LDR) light intensity monitoring, solar cell energy observation, battery charging, and cloud storage. The core idea behind the article is the IoT Solar Charging Station (IoTSCS), and it is tested by comparing it to the Classical Solar Charging Station (CSCS), a more traditional scheme, in order to see how well the new scheme works. © 2024 IEEE.
