Silly Putty - Wikipedia

Silly Putty is a toy based on silicone polymers that have unusual physical properties. It bounces, but it breaks when given a sharp blow, and it can also flow like a liquid. It contains a viscoelastic liquid silicone, a type of non-Newtonian fluid, which makes it act as a viscous liquid over a long time period but as an elastic solid over a short time period.

Nickel Electroplating | Products Finishing

Sep 29, 2011· Boric acid. Boric acid buffers the hydrogen ion concentration (pH) in the hode film. If it were not for this buffering action, the hode film pH in the higher-current-density regions would quickly exceed 6.0, and nickel hydroxide would be precipitated and co-deposited along with hydrogen, resulting in a green nodulation or burned deposit.

Why do different elements produce different colors?

Mar 31, 2020· Boric acid is sold as a roach killer or as a disinfectant. Adding either chemical to a fire yields a vivid green flame. For best results, mix borax or boric acid with methanol, a type of alcohol, and ignite the solution. The alcohol will burn off, leaving behind a white residue from the boron compound.

Boric Acid - an overview | ScienceDirect Topics

Boric acid is dissolved in the reactor coolant to control neutron reactivity in the core, and is referred to as a soluble neutron absorber, soluble poison, or ‘chemical shim’ (Cohen 1964 [26]).Its concentration is adjusted throughout a fuel cycle over a range 0–2500 wppm boron. The high boron level corresponds to the start of a fuel cycle and compensates for excess reactivity in the core.
