Oral bacteria are microorganisms that live in the mouth and can cause various dental problems, such as cavities, gum disease, and bad breath. Some of the most common and harmful oral bacteria are Streptococcus mutans, which produces acid that erodes tooth enamel, and Porphyromonas gingivalis, which is associated with periodontitis, a serious inflammation of the gums…
Formaldehyde is a common indoor air pollutant that can cause various health problems, such as eye, nose, and throat irritation, asthma, and even cancer. However, most existing sensors for formaldehyde are not sensitive or selective enough to detect low levels of the gas or to distinguish it from other volatile organic compounds (VOCs). Researchers from…
Touchscreens are ubiquitous in our daily lives, from smartphones and tablets to kiosks and ATMs. But what about touchscreens for outdoor applications, such as gas pumps, vending machines, or industrial controls? How do they cope with the challenges of weather, sunlight, and durability? In this article, we will explore the factors that make touchscreens suitable…
Electric power distribution is the process of delivering electricity from the generation sources to the end users. It is a complex and vital system that forms the backbone of modern society, powering industries, homes, and devices. It involves the use of high voltage power lines, transformers, substations, and distribution lines, each with their own characteristics…
Power supply batteries are essential components of many devices and systems, such as laptops, smartphones, electric vehicles, and uninterruptible power supplies (UPS). They provide reliable and consistent power when needed, but they also have a limited lifespan. Over time, power supply batteries degrade and lose their capacity, resulting in reduced performance and shorter runtimes. This…
Grow lights are artificial light sources that simulate the natural sunlight for plants. They are widely used in indoor gardening, hydroponics, vertical farming, and greenhouse applications. Grow lights can enhance plant growth, yield, quality, and health by providing the optimal spectrum, intensity, and duration of light. However, grow lights also require a reliable and efficient…
Stadiums are the epicenter of intense sporting events, drawing thousands of spectators who come to witness the thrill and excitement of their favorite teams. However, behind the scenes, a critical aspect often goes unnoticed — stadium lighting. The need for improved energy efficiency in stadium lighting has become increasingly important in recent years, as the…
Remote Operated Vehicles (ROVs) are underwater robots that can perform various tasks such as exploration, inspection, maintenance, and repair. ROVs are widely used in the oil and gas industry, marine science, and military applications. They can operate in harsh and challenging environments that are inaccessible or dangerous for humans. One of the key components of…
Sintered Nd-Fe-B magnets are widely used in various applications such as motors, generators, and sensors, due to their high magnetic energy product and coercivity. However, the increasing demand and price of rare earth elements (REEs), especially Nd and Dy, have posed challenges for the sustainable development of Nd-Fe-B magnets. Therefore, researchers have explored the possibility…
Renewable energy sources such as solar, wind, and hydrogen are expected to play a vital role in the global energy transition, as the world seeks to reduce greenhouse gas emissions and combat climate change. However, these sources also pose some challenges for the power systems that rely on them, as they are variable and uncertain…
