There are two ways to build materials on the nanometer-scale: top-down or bottom-up. Top-down nanomanufacturing involves carving bulk materials to create features with nanometer-scale dimensions. For decades, the process used to produce computer chips has been top-down. How are nanomaterials … Continue reading →

Explanation: A discharging battery behaves like a galvanic cell; therefore, it is characterized by a spontaneous reaction. This means that the reaction happening in a discharging battery has a positive standard reaction potential. Why is discharging a battery spontaneous? When … Continue reading →

Therefore, alkaline batteries should be separated from the rechargeable batteries and disposed of as normal trash. Lead acid batteries are found in Uninterruptible Power Supply (UPS) units and vehicles. These batteries have a lead anode, a lead dioxide cathode and … Continue reading →

The definition of an ionic compound, is a chemical compound composed of ions held together by electrostatic forces – basically held together by ionic bonds. They are formed by neatly packed ions of opposite charge. The compound is neutral, but … Continue reading →

Pencil lead is not lead at all; it’s a combination of finely ground graphite and clay, mixed with water and pressed together at high temperatures into thin rods. We call it lead is because the Englishmen who first discovered graphite … Continue reading →

The most popular car battery is the 063 Type (UK reference number) which is around 21 cm long x 17.5 wide x 17.5 high. The 063 is a 12 volt car battery and generally delivers 42ah, 43ah or 44ah depending … Continue reading →

It is a major industrial metal because of its high ductility, malleability, thermal and electrical conductivity and resistance to corrosion. It is an essential nutrient in our daily diet. And, its antimicrobial property is becoming increasingly important to the prevention … Continue reading →

With most power tools, improvements in technology usually start at the motor, and virtually all electric tool motors, both cordless and plug-in, depend heavily on copper for power. As it turns out, “heavily” is not an understatement. What material are … Continue reading →

To determine how long your battery will last, calculate the battery’s total capacity and divide it by your circuit’s power. Multiply the battery’s reserve capacity by 60. With a reserve capacity, for instance, of 120: 120 x 60 = 7,200. … Continue reading →

Both Lead Acid and Nickel Cadmium batteries produce flammable hydrogen gas during normal charging. Overcharging, excessive heat and many other factors can quickly cause batteries to produce even more hydrogen. As hydrogen builds up, the risk of fire, explosion and … Continue reading →

Attach the negative battery charger clamp to the negative post. Plug the battery charger into a grounded outlet. Charge the battery until the ammeter needle indicates that the battery is charged. Unplug the charger when the ammeter indicates a full … Continue reading →

1. Lead and gel batteries. Despite the age of the technology, lead-acid batteries are still used in backup power systems, road transport, and renewable energy storage systems. Which battery backup is best for home? The best battery backup products to … Continue reading →
