On the transition modes and mechanisms for laminar to turbulent lifted jet diffusion flames at normal- and micro-gravity

open access: yes
Experiments of laminar-to-turbulent jet diffusion flames were conducted in microgravity (mu g) and normal gravity (ng) to investigate effects of liftoff and buoyancy on the flame transition.

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

open access: yesPolymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

Mechanically robust biochar‐modified polystyrene foam with enhanced flame retardancy using halogen‐free additives

open access: yesPolymer International, EarlyView.
Halogen‐free biocomposite polystyrene foams were fabricated via pilot‐scale supercritical CO2 extrusion using expandable graphite, melamine polyphosphate, biochar, and recycled polymer. The optimized formulation exhibited refined cellular morphology, enhanced flame retardancy (limiting oxygen index of 25%, rapid self‐extinguishing), and improved ...

Glass eels and viruses – a lesson learnt from stocking the eastern German Baltic Sea coast

open access: yesTransboundary and Emerging Diseases, Accepted Article., 2022
Abstract Concerns about Anguillid herpesvirus 1 (AngHV‐1) in European eels, especially due to stocking measures, is increasingly coming into focus and raises questions regarding disease monitoring and prevention. In the past, stocking of AngHV‐1‐positive eels into waters assumed AngHV‐1‐free has led to a rapid increase of infected eels in the wild. For

Simulating Arctic Greening: Microbial Responses in Thawing Yedoma Permafrost

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Arctic permafrost soils and sediments store vast amounts of organic carbon. With global warming intensifying, these soils are increasingly exposed to microbial decomposition. Further, Arctic warming and longer growing seasons drive regional greening, potentially accelerating the degradation of the previously frozen organic matter through ...

Development of NMP‐001, A Nitromethane‐Based Green Propellant

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT This paper discusses the development of a model monopropellant that is aimed at exploring the applicability of nitromethane‐based propellants as an alternative to hydrazine. This approach addresses the challenges faced by HAN‐, ADN‐based propulsion by being more cost‐effective while providing similar performance figures.

Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical Monograph Series, Page 133-151., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
