Moulded polystyrene scintillators
Luminescent solid solutions of 1-4 diphenyl-butadiene (DPB), 1-6 diphenyl-hexatriene (DPH), and 1-1-4-4 tetraphenyl-butadiene (TPB) in polystyrene were made by a process of “slow” injection moulding. It turns ...

Polymorphism of Alkyl Sulphate Soaps
ALKYL sulphate soaps NaSO4CnH2n + 1, like the fatty acids and alcohols, may be expected to have a tendency to join together the hydrophylic groups of neighbouring molecules. In the crystalline state, this tendenc...

Light Scattering by Polymer Networks
Non-crystalline polymer networks, whether swollen or not, may exhibit interchain structuring effects due to incompatibility of various parts of the chains (e.g., backbone-side chain or blocks along a copolymer...

Photoregulation of Polymer Conformation
The flow of energy from the Sun out into the universe, absorbed by day and radiated out at night, has brought about on Earth the molecular ordering from which life originated [1]. The same flow has since suppl...

The Rotating Cone Flash Pyrolysis Reactor
The velocity of nearly spherical mono-sized PVC powder in a cold-flow rotating cone reactor (top angle π/3 rad, height 0.43 m) was measured under variation of the particle diameter (140 –780 μm) and the cone r...

Cleaning of Hot Producer Gas in a Catalytic Adiabatic Packed Bed Reactor with Periodic Flow Reversal
To use the product gas of a biomass gasification unit in, for instance, gas engines, its tar content must be reduced to less then 100 mg/Nm3 [1]. A novel technology has been tested which is characterised by perio...

Removal of H2S from coal gas: effect of various parameters on the desulfurization efficiency
After a decade of extensive research, a number of solid sorbents have been identified as being suitable for the high-temperature removal of H2S from coal gas. Current activities are aimed at the development of a ...
