“…One solution was to slow the rate at which inorganic borates ionize boric acid in a physical manner. The other was to form an organic boron crosslinker by combing polyols with the borate ions In the middle of the 1970s, metal crosslinkers with titanium, zirconium, and aluminum, were developed that have the characteristics of delayed crosslinking and high temperature resistance. They are suitable for deep wells above 120 °C .…”

In order to create an improved fracturing fluid, an organic amine boron composite crosslinker (ABC‐1) was prepared from boric acid, triethylenetetramine, ethylene glycol, and mannitol. It has no irritating smell and its synthesis is simple, making it suitable for large‐scale field applications. To illustrate the advantages of the new crosslinker, it was compared to the organic borate crosslinker prepared from boric acid, ethylene glycol, and mannitol. The sand‐carrying capacities, micronetwork structure, and rheological behaviors of fluids with these crosslinkers were investigated at 90, 100, and 110 °C. The results show that the additional BN r covalent bond in the ABC‐1 crosslinker leads to the formation of a denser network structure making it possible to reduce the amount of thickener by about 10%. The temperature resistance could also be enhanced at least 10 °C. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47675.

Analyses of a 20–30 cm thick, completely combusted ash at the 25 × 70 m Tschudi burn at Chan Chan, northern Perú, contain 52–55 wt% SiO2, 180–210 ppm zirconium and are consistent with coal ash. Soil geochemistry across the burn showed elevated calcium and phosphorus content, possible evidence for reported human cremation. A calcined, 5 g, 4.5 cm skull fragment recovered from the burn was confirmed as human by protein radioimmunoassay (pRIA). X‐ray diffraction showed that the bone had been heated to 520°C. The burn took place c. ad 1312–1438 based on interpretation of a 14C date on carbonized plant tinder.
