Restructuring and Cost of Reducing NOx Emissions in Electricity Generation [PDF]

The U.S. electric power sector is in the midst of two major regulatory changes. One is the change from cost-of-service regulation to competition as a means of disciplining electricity prices, often referred to as “electricity restructuring.” The other is

Influence of convective transport on tropospheric ozone and its precursors in a chemistry-climate model [PDF]

, 2005
The impact of convection on tropospheric O3 and its precursors has been examined in a coupled chemistry-climate model. There are two ways that convection affects O3. First, convection affects O3 by vertical mixing of O3 itself.

Magnetic field‐assisted concentration swing adsorption for CO2 capture over Fe3O4/fibrous nanosilica‐PEI adsorbent

AIChE Journal, EarlyView.
Abstract Magnetic field‐assisted concentration swing adsorption (CSA) provides an electrification‐compatible alternative to conventional temperature swing adsorption (TSA) by enabling rapid heating/cooling and energy‐efficient regeneration under near‐isothermal conditions, thereby eliminating the need for sensible heat input.

Surface Anthropogenic NOx Emissions Drive 1995–2014 Increase in Tropospheric Ozone: Implications for Ozone and Methane Radiative Forcing

Geophysical Research Letters
Tropospheric ozone influences Earth's radiative energy budget and has increased in recent decades. With initial‐condition ensembles from a single chemistry‐climate model, we show that global surface anthropogenic NOx emissions explain about 90% of the ...

Machine learning for forecasting factory concentrations of nitrogen oxides from univariate data exploiting trend attributes

International Journal of Advanced Nuclear Reactor Design and Technology
The development of post-processing technology for spent nuclear fuel is essential to ensuring the sustainable growth of nuclear energy. However, post-processing facilities release copious amounts of emissions with high concentrations of nitrogen oxides ...

An Autonomous Large Language Model‐Agent Framework for Transparent and Local Time Series Forecasting

Advanced Intelligent Discovery, EarlyView.
Architecture of the proposed large language model (LLM)‐based agent framework for autonomous time series forecasting in thermal power generation systems. The framework operates through a vertical pipeline initiated by natural language queries from users, which are processed by the LLM Agent Core powered by Llama.cpp and a ReAct loop with persistent ...

Mechanisms driving altitude- and latitude-dependent air quality variations from high-altitude NOx emissions

npj Climate and Atmospheric Science
The environmental impact of nitrogen oxide (NOx) emissions varies with emission altitude and latitude. NOx emissions from subsonic aviation (9-12 km) contribute to net global ozone formation, whereas those from supersonic aircraft (above 14 km) lead to ...

Photochemical regimes in urban atmospheres: The influence of dispersion

Geophysical Research Letters, 2000
The dependence on emissions of urban photochemistry is studied under meteorological conditions favouring pollution episodes. We use a simple chemistry‐transport model, yet realistic with respect to the main chemical and physical processes and considering
