Add them to your roller chain to attach brackets or guides, or to move materials directly. Use them for conveying, timing, and aligning. Connecting links are also known as master links.

Naturally occurring strontium comprises four stable isotopes; 88 Sr is the most common (83%), followed by 86 Sr (9.9%) and 87 Sr (7.0%) (Table 1).The 87 Sr isotope stems both from primordial sources and from the radioactive decay of 87 Rb (half-life = 4.9 × 10 10 years). Depending on the location, therefore, it is possible for 87 Sr/ 86 Sr ratios to differ …

A common pair of fragments from uranium-235 fission is xenon and strontium:. Highly radioactive, the xenon decays with a half-life of 14 seconds and finally produces the stable isotope cerium-140. Strontium-94 decays with a half-life of 75 seconds, finally producing the stable isotope zirconium-94. These fragments are not so dangerous as intermediate …
