Effective use of crop residues as a source material for the production of energy and biochemicals requires a fundamental understanding of its thermal degradation properties and reaction kinetics. Furthermore, identification of applications for lignin and extractives is essential. Thermogravimetric analysis was used to determine the effect of extractives on the thermal decomposition behaviour of...

We investigated the physical and thermal properties of 65 Cybele, one of the largest main-belt asteroids. Based on published and recently obtained thermal infrared observations, including ISO measurements, we derived through thermophysical modelling (TPM) a size of 302×290×232 km (± 4%) and an geometric visible albedo of 0.050±0.005. Our model of a regolith covered surface with low thermal iner...

Solid-state M-2-MeO-Bz compounds, where M stands for bivalent Mn, Co, Ni, Cu and Zn and 2-MeO-Bz is 2-methoxybenzoate, have been synthesized. Simultaneous thermogravimetry-differential thermal analysis (TG-DTA), thermogravimetry, derivative thermogravimetry (TG/DTG), differential scanning calorimetry (DSC), X-ray powder diffractometry, infrared spectroscopy and complexometry were used to charac...

The high carrier mobility and thermal conductivity of graphene make it a candidate material for future high-speed electronic devices. Although the thermal behaviour of high-speed devices can limit their performance, the thermal properties of graphene devices remain incompletely understood. Here, we show that spatially resolved thermal radiation from biased graphene transistors can be used to ex...

Abstract: Cordierite-Mullite based kiln furnitures are widely used in fast-firing of ceramic products because of their low thermal expansion which confer them a very good ability to thermal shock resistance. Difference in CTE of constituent phase can develop damage during thermal cycling due to internal stresses. Increase in industrial competitiveness leads to the development of new means for e...

–Expressions are obtained for the thermal conductivity of some ABO3 type displacive ferroelectrics in paraelectric phase, using Kubo formalism and double time thermal Green’s function technique. The total thermal conductivity obtained for these perovskites which is sum of two terms contributed by optical and acoustical phonons, is in agreement with the experimental results of Steigmeier. The va...

this study investigated single-step extraction of heavy metals from contaminated sedimentscollected in the port of cádiz. experimental tests of washing with an aqueous solution of a chelating agent wereperformed at selected solid/liquid (s/l) ratios. two chelating agents were chosen: 0.3 m edta(ph 3.8 and 8)and sodium citrate (1 m). the objective of the tests was to investigate extractive decon...

nowadays, consumers demand safe and minimally processed foodstuffs without additives and with extended shelf life. as high-pressure processing is used increasingly for the treatment of packed products, different packagings has been investigated with respect to their structural behaviour and stability under high-pressure processing. various defects may ocuure due to high pressure processing such...
