Mine tailings-based geopolymers: A comprehensive review
The functioning of tailing dams increases the likelihood of man-made catastrophes occurring [18, [46], ... The amount of submicron mine tailings and Na 2 SiO 3 in the sample led to a decrease in the sample's ability to absorb water. This is because the sample has a dense structure that does not allow water to pass through [206].

A-tailing
Tailing is an enzymatic method for adding a non-templated nucleotide to the 3' end of a blunt, double-stranded DNA molecule. Tailing is typically done to prepare a T-vector for use in TA cloning or to A-tail a PCR product produced by a high-fidelity polymerase (not Taq) for use in TA cloning.TA cloning is a rapid method of cloning PCR products that utilizes …

LABTips: How to Prevent Tailing Peaks in HPLC
While column overloading is typically more associated with peak fronting or "shark fin" shaped peaks, both mass overload and volume overload could also cause peak tailing across the chromatogram. 7 To test for mass overloading, simply dilute your sample to see if the peak tailing lessens or resolves. For volume overload, try injecting less ...

This special case of peak tailing is usually accompanied by a loss of peak efficiency (peak broadening). If gross stationary phase contamination is suspected, and all other possible causes mentioned above have been explored, trim at least 20cm from the inlet end of the column, re-fit and assess peak shape with a sample or test mix.
