Mechanical and thermal characterization of banana peel fibers/HDPE composites
(2012-01-01)
Lignocellulosic fibers from banana peels were washed with water in order to increase its compatibility with polymeric matrix. These fibers were mixed with high density polyethylene (HDPE) and placed in an injector chamber ...
Thermal study of nickel(II) pyrazolyl complexes
(2005-05-18)
The thermal behavior of the pyrazolyl complexes [NiCl2(HPz) 4] (1), [Ni(NCS)2(HPz)4] (2), [NiCl 2(HdmPz)4]·2H2O (3) and [Ni(NCS) 2(HdmPz)4]·2H2O (4) (HPz=pyrazole, HdmPz=3,5-dimethylpyrazole) has been studied by thermogravimetry ...
Synthesis, characterization and thermal behaviour of solid-state compounds of 4-methoxybenzoate with some bivalent transition metal ions
(2005-05-18)
Solid-state M-4-MeO-Bz compounds, where M stands for bivalent Mn, Co, Ni, Cu and Zn and 4-MeO-Bz is 4-methoxybenzoate, have been synthesized. Simultaneous thermogravimetry-differential thermal analysis (TG-DTA), differential ...
Thermoanalytical study of heavier trivalent lanthanides fumarates
(2013-08-01)
Solid-state heavier lanthanides fumarates compounds have been synthesized, and the compounds were characterized by employing simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning ...
The use of thermogravimetric analysis to characterize the metallic slag aggregates in structural concrete
(2020-01-01)
Structural concretes must have a set of chemical characteristics to present a satisfactory resistance to the degradation in environment conditions. Besides the several types of mineralogical compositions, the calcium-rich ...
Operating Conditions For Oil Shale Thermogravimetry

Phase formation in copper and calcium titanate dielectric ceramic obtained by polymeric precursor method
(2018-01-01)
The polycrystalline ceramic named calcium and copper titanate is a dielectric ceramic with very high dielectric constant applicable in several electronic devices. The powder form for that advanced ceramic can be synthesized ...
Effect of acid hydrolysis conditions on the degradation properties of cellulose from Imperata brasiliensis fibers
(2017-01-01)
The thermal properties of Imperata brasiliensis fibers and cellulose nanofibrils (CNFs), obtained at different conditions of sulfuric acid hydrolysis, were studied in the present work. Imperata Brasiliensis fibers were ...
Biomass-Derived from Bamboo Leaf Ash: Pozzolanic Reactivity
(Materials Research Forum Llc, 2018-01-01)
Bamboo leaf ash (BLA) was assessed as a pozzolanic material in pastes and mortars. Differently from most of research performed, the BLA studied in this paper was obtained through an auto-combustion process. This material ...
