The paper presents the combustion profile of selected fuels as a result thermogravimetric analysis. main purpose this study was to investigate mixture different types fuel and influence use additive on process profile. As additive, halloysite used profiles. It confirmed that parameters such ignition temperature, burnout maximum peak temperature correlated accordingly with combustibility indices...

Ternary Ni(II) complexes of hydrazine and eight heterocyclic sulfonamides possessing carbonic anhydrase (CA) inhibitory properties, were prepared and characterized by elemental analysis, spectroscopic, magnetic, thermogravimetric, and conductimetric measurements. The complexes behave as strong inhibitors for two isozymes (I and II) of carbonic anhydrase.

Complexes of the diuretic benzothiadiazine derivative chlorothiazide (6-chloro-7-sulfamoyl- 1,2,4-benzothiadiazine-1,1-dioxide) with V(IV); Fe(II); Co(II); Ni(II); Cu(II), Ag(I) and U(VI) were prepared and characterized by elemental analysis, spectroscopic, thermogravimetric, magnetic and conductimetric measurements. The complexes behave as effective inhibitors for two isozymes (I and II) of ca...

To determine the influence of electrochemical polarization of PtRu/C catalysts on methanol electrooxidation, this work investigated methanol electrooxidation on as received and different electrochemically polarized PtRu/C catalysts. Thermogravimetric analysis (TGA) and X-ray diffraction (XRD) were used to characterize the redox state of PtRu/C after different electrochemical polarization. The m...

Catalytic sequential hydroboration of decaborane for the synthesis of poly(organodecaborane), with decaborane in the mainchain, is reported for the first time. Under a platinum catalytic system, poly(6-hexenyldecaborane) and poly(6-norbornenyldecaborane) are obtained with well-defined structures and a moderate yield. Thermogravimetric analysis demonstrates that the char yields are 73% and 82%, ...

Two samples of hydrated silica from the bamboo plant ( t̀abasheer’ and `bambusa’ ) were examined by X-ray ̄ uorescence and H, Al and Si solidstate NMR, X-ray di€ raction and thermogravimetric analysis. Silicon is the major elemental component of both samples, with much smaller amounts of aluminium (about 1 2́wt%), iron (0 3́± 0 4́wt%), calcium and magnesium, and traces of phosphorus . The maximum t...

Three derivatives of thieno[3,2-b]thiophene end-capped with phenyl units have been synthesized and characterized by MALDI TOF mass spectroscopy, elemental analysis, UV-vis absorption spectroscopy and thermogravimetric analysis (TGA). All compounds were prepared using Pd-catalyzed Stille or Suzuki coupling reactions. Optical measurements and thermal analysis revealed that these compounds are pro...

A moisture-triggered release system was developed using porous metal-organic materials as encapsulating agents. Release of both hydrophilic (ethyl butyrate) and hydrophobic (D-limonene) fragrance compounds was investigated by gas adsorption measurement, thermogravimetric analysis and gas chromatography-mass spectroscopy. These materials exhibit exceptional fragrance compatibility and controlled...
