Microalgae Spirulina sp which has been cultivated by the Brackishwater Aquaculture Development Center, Situbondo Indonesia were tested for their potential energy performance using proximate analyzer, SEM-EDX, and thermogravimetry. The analyzer showed volatile matter (VM), fixed carbon (FC), moisture, ash content (AC), total sulfur of microalgae 68.15, 12.57, 11.22, 8.06, 0.67 (wt%, ar), respect...

Coordination compounds of Co(II), Ni(II), Cu(II), Zn(II), and Cd(II) with 1,3,4-thiadiazole-2,5-disulfonamide as ligand were synthesized and characterized by IR and UV spectroscopy, conductimetry and thermogravimetry. The parent ligand is a very weak carbonic anhydrase (CA) inhibitor, although it constituted the lead for developing important classes of diuretics. The complex derivatives behave ...

A metal-organic framework based on 5-iodo-isophthalic acid (5-iipaH2) and the ancillary nitrogen ligand 1,3-bi(4pyridyl)propane (bpp), namely [Cd(5-iipa)(bpp)(H2O)]n (1), has been synthesized, and characterized by IR spectroscopy, elemental analysis, thermogravimetry, and X-ray crystallography. Complex 1 shows a two-fold interpenetrating 3D diamond-like architecture that is stabilized by hydrog...

Ipidacrine hydrochloride is pharmaceutically active compound that forms variety of crystalline modifications which differs by solvent type and content in crystalline structure. These crystalline forms analyzed by powder x-ray diffraction, differential thermal analysis, thermogravimetry and Karl Fisher titration. Obtained crystalline forms include two monohydrates, two hemihydrates, two anhydrou...

The drying conditions for primary standards of volumetric analysis have a significant effect on the titration results due to changes in the purity, stability and homogeneity. Amidosulfuric acid, a strong acid used as a reference material for volumetric analysis in Japan, was dried in a vacuum desiccator or heated at different temperatures, and then measured by Karl-Fischer titration, thermograv...
