Chitosan Oligosaccharide Cross‐Linked Piperazine Pyrophosphate/Melamine Polyphosphate Modified Silicone‐Acrylic Emulsion‐Based Flame‐Retardant Coating

open access: yesSafety Science and Technology, EarlyView.
Chitosan oligosaccharides, as the modifier, significantly enhances the crosslinking degree of piperazine pyrophosphate and melamine polyphosphate, enabling the composite coating to form the interpenetrating network integrating Si‐P‐C‐N during combustion.

Using Visual Systems Mapping to Improve Transparency and Comparability of Life Cycle Assessment Baseline Scenarios

open access: yesSystems Engineering, EarlyView.
ABSTRACT Visual systems mapping is a systems engineering approach used to represent complex processes and interactions. This study evaluates its application for documenting assumptions in life cycle assessment (LCA) baseline scenarios. In LCA, the baseline or reference case represents the business as usual system against which changes in impacts (e.g.,

The UK Clean Air Act at 70: An interdisciplinary analysis of historical air quality change

open access: yesWeather, EarlyView.
2026 marks the 70th anniversary of the first UK Clean Air Act, a pivotal moment for air quality in modern British history. Previous narratives on this legislation have largely centred on pollution in London and monodisciplinary perspectives. This article integrates historical research with reconstructed estimates of PM2.5 concentrations to spotlight ...

Radionuclide emissions from a coal-fired power plant

Applied Radiation and Isotopes, 2013
Current study concerns measurement of radioactivity levels in areas surrounding a 2420 MW thermal power plant fueled predominantly by bituminous coal. The concentrations of (226)Ra, (232)Th and (40)K in onsite bottom-ash were found to be 139 Bq/kg, 108 Bq/kg and 291 Bq/kg, respectively, the levels for these radiolnuclides in soil decreasing with ...
