  • We demonstrate an efficient bulk heterojunction (BHJ) organic solar cell (OSCs) utilizing a soluble phthalocyanine derivative, 1,4,8,11,15,18,22,25-octahexylphthalocyanine (C6PcH2), and a fullerene derivative, 1-(3-methoxy-carbonyl)-propyl-1-1-phenyl-(6,6)C71 and roles of processing additive solvent on improvement of the BHJ OSCs.

  • This research aimed at investigating the effects of extraction parameters on the extraction efficiency and chemical characteristics of Trungdu tea (Camellia sinensis O. Kuntze) seed oil, which is similar to olive oil with high portion of unsaturated fatty acids, especially essential linoleic acid and low content of saturated fat. The study parameters were particle size (0.25 - 2.00 mm), material/solvent ratio (1/12 - 1/6), temperature (25 - 55 oC), time (5 - 11 h), speed of solvent movement (0 - 250 r/m) and extraction times (1 - 3 times).

  • Addition of Surrogates and Matrix Spiking Compounds in the Field: It is best to add analytical surrogate and matrix spiking compounds into soils prior to sample extraction, using water or a solvent. Method 5035A does not incorporate the addition of these compounds prior to extraction in the field. Because this is an important control check on the analytical process, it may be appropriate to incorporate a procedure which adds surrogate and/or matrix spiking compounds prior to extraction for some project/program DQOs.

  • Human activities have a large and important impact on the environment. Naturally occurring elements or compounds are often concentrated and redistributed in the environment through industrial processes, power production, and consumer activity. For example, lead, which is found in naturally occurring mineral deposits, has become a major pollutant through its use in batteries, paints, and gasoline additives.
