ESSENTIAL AND VEGETABLE OILS: RAW MATERIALS FOR THE MANUFACTURE OF BIOPRODUCTS IN CLASSES EXPERIMENTAL ORGANIC CHEMISTRY. A schedule was prepared for three undergraduate classes the discipline of experimental organic chemistry obtaining bioproducts. As natural raw materials, lavender flowers and cinnamon peels were used to obtain hydrolates essential oils (Class 1), coconut avocado pulp vegetab...

Ascorbi acid in serum was determined by the method of Mindlin and Butler (2) with the following modifications. (1) Neither potassium oxalate nor potassium cyanide was used. An anticoagulant was not necessary because the blood was defibrinated by stirring with a glass rod. The possible erroneous influence of added KCN has been demonstrated by other observers (3, 4, 5), as well as in this laborat...

Co-sensitized solar cells have gained more attention due to the ability of energy conversion process by absorbing photons from wide range spectrum including visible and near-infrared region. TiO2 electrodes were co-sensitized with PbS/CdS core-shell quantum dots N719 dye. PbS/CdS/N719 dye-sensitized fabricated poly(ethylene oxide) based solid polymer electrolyte consisting iodide/triiodide redo...

The counter electrode plays major role in achieving of maximum performance dye-sensitized solar cells (DSSCs). A mixture jack-fruit latex and activated charcoal is used for the first time DSSCs as material. Maximum short-circuit photo-performances 3.2 mAcm-2was achieved TiO2|mercurochrome|(I-/I3-) at optimal amount binder percentage 15% jackfruit latex, under AM 1.5 conditions.

The use of nucleic acid staining with a fluorochrome dye to differentiate viable and dead (heat-killed) Cryptosporidium oocysts was assessed. The specificities (percentage of unstained viable oocysts) and sensitivities (percentage of stained dead oocysts) of the seven tested dyes (SYTO-17® and SYTO-59® to 64®) ranged from 65 to 76% (average 71%) and 83 to 95% (average 91%), respectively. SYTO-5...
