Nickel, a versatile transition metal, has emerged as a key material in modern battery technologies due to its excellent storage capacity and higher energy density at a relatively lower cost. Its ability to resist high voltages and prevent overheating makes it an ideal choice for various battery applications, including electric vehicles, portable devices, and even satellites. Nickel-based batteries, from the early Nickel-Cadmium (NiCd) to the latest Nickel-Rich Lithium-Ion batteries like&nbs …

Access to clean water is a critical objective within the United Nations' sustainable development framework. To meet this global challenge, innovative solutions in water purification are urgently needed. One promising advancement lies in the application of graphene technology. Graphene, discovered in 2004, has revolutionized water filtration by enabling membrane-based purification without chemical processes. This material, composed of carbon atoms arranged in a honeycomb structure, exhi …

A coin cell is a round cell-type battery that has a flat shape and is generally small in size. This type of battery, also known as a button cell, is commonly used as a power source in various portable electronic devices, including watches.It derives its name from its resemblance to a coin in shape. Coin cell batteries come in different diameters and thicknesses, but the most commonly used ones have model numbers like CR2032, CR2025, and CR2016. In addition to being used as power sources fo …

Carbon dioxide (CO2) sensors have an important position in our lives in many different application areas. Detection of CO2 makes possible to take precautions for unexpected cases such as fire or it can be used in air-quality and greenhouse-gas monitoring. Metal oxides are used sensors for these purposes. Researchers have been trying to reduce costs and size of these sensors because these parameters limit the usage of this sensor for some certain purposes. Also, metal oxide sensors sho …

Titanium Oxide (TiO2) is an important material having a lot of vital properties and applications such as the production of titanium metal, titanium oxide nanoparticles, etc. It has two important types which are rutile titanium dioxide and anatase titanium dioxide. The key difference among them is in their appearance. Anatase Titanium Dioxide is colorless, whereas Rutile Titanium Dioxide is usually found in dark red appearance. Rutile titanium dioxide is optically positive, w …
