Luminescent Materials Luminescence is an energy state transition that results from chemical changes, electrical energy, subatomic motions, reactions in crystals, or stimulation of an atomic system. Luminescent materials are an important class of devices for display and lighting applications. However, they are susceptible to thermal degradation. Increasing their quantum efficiency (QE) and thermal stability is […]
Arthroscopy Arthroscopy is a surgical procedure doctors use to look at, diagnose, and treat problems inside joints. Most often, it’s done on the knee, shoulder, elbow, ankle, or wrist. To do an arthroscopy, your doctor will insert pencil-thin tools through small cuts (incisions). These tools have a camera lens and light. The surgeon will also […]

They’re looser and softer than straight or skinny jeans, but still have the definition at the waist and hips that […]
Alkaline Manganese Battery Alkaline manganese battery is one of the most popular primary batteries used today. Its major advantages include high energy capacity, low self-discharge rate, and long lifespan. A typical alkaline battery is composed of a reagent-grade manganese dioxide (MnO2) cathode and a basic potassium hydroxide electrolyte. It also contains zinc metal powder as […]
Alkaline Manganese Cell The alkaline manganese cell is a variant of the Leclanche cell, but with electrodes of zinc and manganese dioxide. It uses potassium hydroxide as the electrolyte. It is a popular primary general purpose battery. It has as much as double the energy density of a rechargeable Nickel based cell such as NiCad […]
Lithium Manganese Button Battery A button battery is a small primary lithium-ion battery that uses manganese dioxide for the positive electrode and zinc for the negative electrode. It’s used in a wide range of products. Button batteries are a dangerous choking hazard for young children and should be kept away from them. These can cause […]
Why Choose a USB Rechargeable Battery? USB rechargeable batteries are a good choice for a number of reasons. They’re long-lasting, have better performance and are more eco-friendly than standard batteries. Unlike traditional batteries, USB rechargeable batteries charge with a standard microUSB and don’t require a special charger. This makes them super portable. Long-Lasting Rechargeable batteries […]
