Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

Groundwater Monitoring &Remediation, EarlyView.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

Study on Thermal Degradation Characteristics and Regression Rate Measurement of Paraffin-Based Fuel

Energies, 2015
Paraffin fuel has been found to have a regression rate that is higher than conventional HTPB (hydroxyl-terminated polybutadiene) fuel and, thus, presents itself as an ideal energy source for a hybrid rocket engine.
