Features of the mechanism of pasty propellants burning
DOI: 10.1016/j.enmf.2023.10.002 Read Article
Baltic state technical university | 2023The composition of a pasty propellant for small-sized space engines has been proposed. For this propellant, a research of the burning process was carried out. This research included the determination of the burning rate law, the characteristics of the agglomeration process, and the properties of the surface layer. The presence of an intermediate structure, a skeleton layer, during the burning of such propellants, and the nature of the influence of pressure, additives, and the size of oxidizer particles on this structure, have been established. The determining influence of this structure on the burning process is shown. Composition solutions that provide control over the burning rate law of such propellants are determined. These solutions make it possible to change the absolute value of the burning rate, as well as its dependence on pressure. Regularities of the agglomeration process have been established. These regularities are associated with the features of the formation of the skeleton layer, which depend on the structure of the propellant, pressure, and the presence of additives. - BeVision S1
Challenges on pumping infra-lightweight concrete based on highly porous aggregates
DOI: 10.1016/j.jobe.2022.105761 Read ArticleUniversität der Bundeswehr München | 2022Infra-lightweight concrete (ILC) is the latest step in the development lightweight concrete mainly for the use in monolithic exterior walls. By optimizing the balance between reduced density, sufficient strength and the lowest possible thermal conductivity, ILC offers a competitive alternative to multilayer wall structures commonly used today. Pumping of fresh concrete is becoming increasingly important owing to further rationalization on the construction site and the increasing use of ready-mix concrete. However, pumping lightweight concretes is often associated with difficulties. This article presents the first study ever on pumpability of a record breaking ILC, using some of the most common concrete pumps. Therefore, an experimental study was carried out to determine whether the pressurization of the fresh concrete in the course of the pumping process influences fresh and hardened ILC properties. Based on the results, it can be concluded that ILC can be pumped. The delivery principle of the pumps has a particular influence on fresh ILC properties, especially in terms of abrasive stress on the porous aggregates and workability. No significant negative influences on hardened concrete properties were detected. Classification of the ILC can be accomplished in the same density and strength class before and after pumping. The study highlights challenges of pumping ILC with highly porous aggregates and provides practical approaches to its realization. - BeVision S1
Identification and characteristic analysis of powder ejected from a lithium ion battery during thermal runaway at elevated temperatures
DOI: 10.1016/j.jhazmat.2020.123169 Read ArticleNanjing University of Science and Technology | 2020The thermal runaway of a lithium ion battery under abusive conditions has become an urgent problem in recent years. The thermal runaway generates flammable and toxic gases and ejects a hazardous black solid powder. Although relevant research on gas vented from thermal runaway has been studied in recent works, the composition, hazardous characteristics and formation process of the ejected powder remain unclarified. To investigate the hazardous characteristics of the ejected powder products and further provide insights into the thermal runaway mechanisms of lithium ion battery in terms of the identified components, a series of instrumental tests were performed and analyzed in this work. The results show that the powder ejected from the thermal runaway of a lithium ion battery is composed of carbon, organic chemicals, carbonate, metal, metal oxides and other impurities. Different states of charge of the lithium ion battery, heating modes and environmental atmospheres have certain effects on the formation of the ejected powder. These effects include the production of slightly different components in the ejected powder and changes in the particle sizes. The ejected powder is produced via a complex formation process and is hazardous due to its organic components, metal and metal oxides. - BeVision S1
Probiotic encapsulation in water-in-water emulsion via heteroprotein complex coacervation of type-A gelatin/caseinate
DOI: 10.1016/j.foodhyd.2020.105790 Read ArticleShanghai Jiao Tong University | 2020The production of dried probiotic bacterial cells that are shelf stable at room temperature remains challenging. In this work, the potential of encapsulation of probiotic Lactobacillus reuteri using heteroprotein complex coacervation (type-A gelatin/sodium caseinate, GE/Cas) was compared to a protein/polysaccharide complex coacervation (type-A gelatin/gum arabic, GE/GA). The optimal pH and GE/Cas ratio for formation of water-in-water emulsions were found to be pH = 6.0 and GE/Cas = 2.0. L. reuteri TMW1.656 survived spray drying without loss of viability; the survival after simulated digestion, heating and ambient storage decreased in the order GE/Cas ≥ Cas > GE/GA > GE. The improved protection of the GE/Cas matrix was related to a reduced hygroscopicity, solubilization and wettability, and may be caused by the relatively higher hydrophobicity of GE/Cas heteroprotein coacervation system. To the best of our knowledge, this is the first study employing heteroprotein coacervation to encapsulate probiotics.
