Battery is any device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. Batteries are made from many materials including various metals, carbon, polymers and even air. The most common are lead-acid batteries used in vehicles and lithium ion batteries used for portable electronics. Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to battery banks the size of rooms that provide…Continue

A fiber that has a width of less than 1000 nanometers (1000 nm or 1 µm) is generally defined as a nano fiber. A nanoparticle is defined as a small group of atoms or molecules with a radius of less than 100 nanometers (100 nm). Particles on the nanoscale have a very high surface area to volume ratio, whereas this ratio is much lower for objects on the macroscopic scale.
Nanofabrics are textiles engineered with small particles that give ordinary materials advantageous properties…

Food supply worldwide is under constant threat and effective test products that can ensure food safety are in demand. Microbial pathogens such as bacteria, viruses, environmental toxins, food allergens and adulterants, residues of drugs and agricultural chemicals can harm consumers if unchecked. In some countries, testing for Genetically Modified Organisms (GMOs) is also conducted to ensure food authenticity. Although pathogen testing is still the most dominant segment of food testing,…Continue
