Biomass-charcoal fuel with good burning characteristic

Abstract: The invention discloses biomass-charcoal fuel with good burning characteristic and relates to the technical field of biological environmental protection. The biomass-charcoal fuel is prepared by the steps of: after mixing charred materials obtained by crushing and charring triarrhena lutarioriparia stems with graphene-oxide-modified corn straw powder, adding into a biomass forming machine and pressing. The prepared biomass-charcoal fuel has the beneficial effects that the comprehensive burning characteristic index of the biomass-charcoal fuel is higher than that of charcoal, therefore, the prepared biomass-charocoal fuel has batter burning characteristic; the average ignition point of the biomass-charcoal fuel is 255 DEG C, while the ignition point of common charcoal is 480 DEG C, therefore, the prepared biomass-charcoal fuel has lower ignition point and is easier to burn.

Prediction of thermal ablation in rocket nozzle using CFD and FEA

Abstract: To protect the structural part of the rocket nozzle, an insulation liner is provided at its inner surface. Charring ablators are used for this purpose. The thickness of the insulation liner is one ...

Multidisciplinary Forensic Approach in “Complex” Bodies: Systematic Review and Procedural Proposal

Abstract: The recovery of severely altered cadavers (i.e., extensively decomposed, mummified, charred or dismembered) can be a challenge for forensic pathologists due to the difficulties in identification, PMI estimation and manner and cause of death determination. In such cases, integrating routine approaches (autopsy, histology, toxicology) to more specific forensic branches can be fundamental to improving the investigative process. In this paper a systematic review using PubMed, Scopus and Web of Science databases has been performed. The aim was to evaluate the forensic approaches implemented in the management of severely altered bodies due to decomposition, mummification, skeletonization, charring or dismemberment (to which we refer to as “complex”), and the role of each approach in the solution of a case. Then, the literature revision results were used to propose a schematic flowchart summarizing the post mortem activities that can be performed in forensic practice, adaptable in relation to each case.

charring ablative materials

Abstract: Normal emissivity of ablative thermal insulators at different temperatures is determined comparing the radiation emitted and the surface temperature for a cylindrical sample. A microthermocoupl e (diameter 50 j.lm) is carefully inserted under a very thin sublayer of the surface sample and a C02 laser is used to heat it at different temperatures. The sample is observed by an infrared camera which allows the determination of the radiating energy emitted from its surface in the wavelength interval of 3.0 -5.4 j.lm.
