The rapid pyrolysis of GAP/AP system under simulated combustion conditions was investigated by an on-line analysis, i. e. so called T-Jump/FTIR. The results show that the compositions of the main gaseous products for pyrolysis are changed, in comparison with the pyrolyses of single, which indicates that the interactions occur between the components of GAP/AP system. From an obvious effect of pressure on the main gaseous products for GAP/AP pyrolysis it is shown that the interactions between GAP and AP components arise from the gaseous products of AP and both the reactions in gas phase and in gas/condensed phase occur in the GAP/AP mixed system. The interactions between GAP and AP are not affected by test temperature. It is considered that the real time analysis of gaseous products of energetic material pyrolysis under simulated combustion conditions would be carried out by T-Jump/FTIR on-line analysis technique and from microcosmic reaction a technical approach used to explore the rapid pyrolysis of energetic materials and interactions between their components at high temperature and pressure would be developed by the on-line analysis technique from microcosmic reaction.

Sustainable removal of gaseous Hg using sulfur functionalized biochar: Adsorption experiment and life cycle assessment.

Maximizing the sorption capacity of gaseous Hg by sulfur-functionalized biochar can lead to increased energy consumption and the production of secondary environmental pollutants such as greenhouse gases. This study evaluates the environmental impact of producing sulfurized biochar through a life cycle assessment (LCA), weighing these impacts against the benefits of enhanced Hg removal efficiencies. The biochar's Hg adsorption capacity, which ranges between 3 and 22 μg-Hg/g-biochar, is influenced by several factors: it increases with higher sulfur loading (0-15 %), higher O levels (0-21 %), and longer pyrolysis times (1-5 h).

Emerging strategies for nitric oxide production and their topical application as nanodressings to promote diabetic wound healing.

The challenges associated with prolonged healing or non-healing of chronic diabetic wounds contribute significantly to the increased incidence of lower limb amputation. A pivotal factor in the impediment of healing is the reduced production of endogenous nitric oxide (NO) due to the hyperglycemic microenvironment typical of chronic diabetes. While both endogenous and exogenous NO have been shown to promote the healing process of diabetic wounds, the direct application of NO in wound management is limited due to its gaseous nature and the risk of explosive release.

The increasing CO concentration in the atmosphere has substantial impacts on the global temperature. For energy sustainability and minimization of the effects of global warming, an approach to understand CO capturing and a carbon neutral culture is extremely essential in the present circumstances. The CO emission from vehicles and industries can be minimized using energy cost-effective techniques and can be converted more selectively into reusable fuels via thermochemical, electrochemical, photochemical, photocatalytic, electrocatalytic, biological and inorganic carbonate-based approaches.
