cement. An off-line instrument that detects carbon in fly ash via the photoacoustic effect has been developed. This instrument has been used to measure fly ash carbon concentrations from less than 0.1% to nearly 7% by mass. The applicability of a theoretic model to the empirical results is discussed

'HATS': the future of long-term thermal stabilization of polyolefins Schmutz, T. Per. Coal, 1995, 37, (3), 44-49. This paper shows the performance of Tinuvin 622, Chimassorb 944 and Chimassorb 119 as hindered amine thermal stabilizers (HATS) in thin and thick polypropylene articles. Data are presented illustrating the benefit of using these high-molecular weight compounds for long-term thermal stabilization of polypropylene.
The performance in a variety of filled and unfilled, pigmented and unpigmented polypropylene grades is shown and typical applications are discussed.

Although coal may be viewed as a dirty fuel due to its high greenhouse emissions when combusted, a strong case can be made for coal to be a major world source of clean H 2 energy. Apart from the fact that resources of coal will outlast oil and natural gas by centuries, there is a shift towards devel
