Thermal degradation of geomembranes after exposure to heat
(Millpress Science Publishers, 2006-01-01)
HDPE and PVC geomembranes are sensitive to changes in their properties when in contact with high temperatures. The effects of hot temperature on polymeric geomembranes are assessed by the ASTM D794 and ASTM D5721.This paper ...
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 ...

Thermal behavior of pyrazolyl complexes [PdCl2(HPz)2] (1), [PdCl2(HdmPz)2] (2), [Pd(SCN)2(HPz) 2] (3), [Pd(SCN)2(HdmPz)2] (4), [Pd(N 3)2(HdmPz)2] (5), [Pd(PzNHCO)2] (6) and [Pd(dmPzNHCO)2] (7) (HPz=pyrazole, HdmPz=3,5-di ...
Physical-chemical and thermal characterization of powder eucalyptus bark
(2020-01-01)
Eucalyptus bark is an agroindustry residue generated in large quantities due to its physical-chemical characteristics. Several industries, such as the pulp and paper industry, the timber and derived industries, do the wood ...
In-Flight Analysis and Microstructural Evaluation of CoNiCrAlY Coatings Deposited by HVPS
(Asm International, 2018-01-01)
The plasma torch design affects the particle-plasma interaction, in-flight properties and the coating microstructure. When spraying metallic powders, the in-flight oxidation as well as the particle velocity and temperature ...

Analytical/numerical hybrid solution for one-dimensional ablation problem
(2003-12-01)
Ablation is a thermal protection process with several applications in engineering, mainly in the field of airspace industry. The use of conventional materials must be quite restricted, because they would suffer catastrophic ...
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 ...
