Chromium-vanadium steel is an alloy made of iron with carbon, chrome and vanadium added to improve the properties of the metal. These alloys vary by percentage of additives; they commonly are stronger at high temperatures.
Chrome-vanadium steel combines strength with flexibility. Alloys of this steel with high carbon content are used to make wear-resistant ball bearings, while medium-carbon alloys are made into tough springs. Heat-treated chrome-vanadium steel is particularly resistant to wear and fatigue and is often used for high-speed applications such as drill bits and power-saw blades. The addition of vanadium makes steel more easily shaped without the danger of breaking.Learn More
A laminar flow occurs when fluids flow in layers that are parallel without any disruptions between the layers. The particles in fluids flow in an orderly motion in straight lines that run parallel to the pipe wall.Full Answer >
As of 2014, a novel material called upsalite is the world's most water-absorbent material. Made of nanostructured anhydrous magnesium carbonate, this material is capable of absorbing several hundred times its weight in water, even in low-humidity conditions. Other record-breaking water absorbent materials include sodium methacrylate, hygroscopic zeolites and poly(N-isopropylacrylamide)-coated cotton fabrics.Full Answer >
The function of a test tube brush is the clean test tubes used in a science laboratory. Test tube brushes are also useful in cleaning aquarium tanks. They consist of twisted wire handles connected to bristles that are made of Nylon or a similar material such as Tynex.Full Answer >
A measuring cylinder is used in a laboratory for measuring exact quantities of a liquid. It is also called a graduated cylinder, as it is marked with precise measurements. It is useful in the pharmacy industry, where even minute quantities of a liquid can make a difference.Full Answer >
