This article describes how the advanced LaserNet Fines (LNF) Q200 instrument in the lab offers an economical, precise solution to conventional methods of analyzing oil debris particles.
The last decade has seen historic rises in metal prices, and inevitably this has led to an equally large rise in metal thefts.

Alloy 925 is a precipitation-hardenable nickel-iron-chromium alloy added with copper and molybdenum. It exhibits high strength and excellent resistance to pitting, crevice corrosion, and stress-corrosion cracking in many aqueous environments containing chlorides and sulfides.
Alloy 59 is a nickel-chromium-molybdenum alloy having high mechanical strength and excellent corrosion resistance. The alloy also possesses high resistance to stress corrosion cracking, chloride pitting and oxidizing and reducing media.
Alloy 690 is a high-chromium nickel alloy that exhibits excellent resistance to many corrosive aqueous media and high temperature environments. It has good fabrication characteristics, metallurgical stability and high strength.
Alloy 926 is a super-austenitic molybdenum stainless steel that exhibits excellent resistance to a variety of highly corrosive environments.
ZE41 alloy is a magnesium casting alloy containing zirconium, rare earths and zinc. This alloy is well-suited for high integrity castings that are operated at ambient temperatures or up to 149°C (300°F). It is easily weldable and pressure-tight.
ZK61 alloy is a Mg-Zn-Zr alloy having higher creep resistance and good tensile properties at both room and elevated temperatures. This alloy is normally used in T6 tempers and susceptible to microporosity. It is not weldable, and hence its practical applications are severely restricted.
A working transparent speaker has been produced that uses ions, rather than electrons, to carry the electrical charge.
