Powder x‐ray diffraction of two‐dimensional materials
D. Yang,R. F. Frindt +1 more
TL;DR: In this paper, an analytic solution for the normalized intensity for powder x-ray diffraction has been obtained for a simple two-dimensional lattice using a linear approximation for the interference function.
Journal ArticleDOI
Reduction of heat transfer fouling by the addition of wood pulp fibers
TL;DR: In this paper, a small quantity of softwood chemical pulp fiber was added to the bulk of the CaS04 solution to reduce the rate of fouling in a closed-loop test rig containing an externally heated test section.
Journal ArticleDOI
Studies of organophilic clays: the distribution of quaternary ammonium compounds on clay surfaces and the role of impurities
TL;DR: Wyoming bentonite (predominantly Na+ form) was shown to contain quartz as a major impurity, together with a number of minor impurities Air refinement of the clay gave some separation by particle size, but impurity phases persisted in both the coarse (73-188 μm) and fine (19-98 μm), fractions Exchange of the clays with a long-chain alkyl quaternary ammonium salt, R2NMe2 · Cl (R = C18 64%; C16, 3116 % ; C16 4%; C12
Journal ArticleDOI
Al2O3 thin films by plasma-enhanced chemical vapour deposition using trimethyl-amine alane (TMAA) as the Al precursor
C.E. Chryssou,C.W. Pitt +1 more
TL;DR: In this article, the authors used trimethyl-amine alane (TMAA) as the Al precursor to obtain stoichiometric alumina with low carbon contamination (0.7-1.3%) and a refractive index ranging from 1.54 to 1.62.
