Single crystals of pure and ammonium chloride-doped urea L-malic acid (ULMA) were grown by slow evaporation technique. Many interesting results on several properties of ammonium chloride impurity added to ULMA single crystals have been observed and studied. The different morphology of ammonium chloride-doped ULMA crystals was noticed and the effect of ammonium chloride doping on the growth, optical, and hardness properties has been investigated. The presence of functional groups has been estimated by FTIR analysis. The lattice parameters of the grown crystals were studied by single crystal X-r

A cationic polymeric flocculant was synthesized through solution polymerization. The polymerization was initiated by acrylamide and Aacryloxyethyltrimethyl Ammonium Chloride(DAC) monomers, and ammonium persulfate and sodium sulfite as redox initiation system. The copolymer obtained was characterized by Fourier-transform infrared (FTIR) spectroscopy. Its flocculating properties were evaluated by turbidity removal with clay suspensions, turbidity and COD removal with sewage using standard jar tests. The results demonstrate that the copolymer can be used as a kind of cationic polymeric flocculant

The technique offers new opportunities in modification of polyolefins, which has advantages of being solventless and having a lower process temperature.

The Larmor frequency was 2 MHz and the echo spacing 0.16 ms. Mild compaction was achieved by centrifuging the clay slurry at three successive pressures ranging from 1 to 125 psi. High
