Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University The United States consumes a large amount of energy – the current rate is around 97.5 quadrillion BTUs annually. The vast majority (90%) of this energy comes from non-renewable fuel sources. This energy is used for electricity (39%), transportation (28%), industry (22%), and residential/commercial use (11%). As the world has a limited supply of these non-renewable sources, the United States (among others) is...

We present a unique platform for characterizing electrode surfaces in solid oxide fuel cells (SOFCs) that allows simultaneous performance of multiple characterization techniques (e.g. in situ Raman spectroscopy and scanning probe microscopy alongside electrochemical measurements). Complementary information from these analyses may help to advance toward a more profound understanding of electrode reaction and degradation mechanisms, providing insights into rational design of better materials for...

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

We describe the use of micro-thermocouples to estimate local temperature gradients in steady laminar boundary layer diffusion flames. By extension of the Reynolds Analogy, local temperature gradients can be further used to estimate the local mass burning rates and heat fluxes in such flames with high accuracy.

FAQs
Oxygen availability influences whether combustion proceeds more completely or incompletely. Under combustion conditions, hydrocarbons react with oxygen at high temperatures and release heat, carbon dioxide, and water. When combustion is incomplete, carbon monoxide, particulate matter, and nitrogen oxides may also form. This distinction matters because the additional pollutants create different environmental and biological concerns than carbon dioxide alone.
These compounds represent major products of incomplete combustion and help explain why emissions have effects beyond energy production and carbon dioxide release. Their presence connects combustion conditions with air-pollution concerns and organismal health. In biological research, tracking these pollutants supports analysis of how altered environmental conditions may influence organisms and contribute to broader ecosystem disruption.
Fossil fuel burning links atmospheric and biological systems through the substances released during combustion. Carbon dioxide is relevant to climate change, while other emissions contribute to air pollution. These atmospheric changes can influence ecosystems and organismal health, allowing biology to examine how environmental alterations extend from large-scale atmospheric processes to responses in living systems.
A biology-focused study connects the emissions from fossil fuel burning with changes in atmospheric conditions, ecosystem function, and organismal health. Researchers can use this framework to examine climate change and air pollution as related pressures rather than isolated issues. The resulting perspective helps explain how combustion-associated environmental changes may affect biodiversity and biological systems.
Relevant outcomes include effects on organismal health, disruption of ecosystems, and potential consequences for biodiversity. These outcomes provide a biological context for interpreting atmospheric emissions and climate-related changes. Examining them together helps determine how fossil fuel burning influences living systems at multiple levels, from individual physiological responses to broader ecological patterns.
The topic provides a way to connect cellular and physiological responses with climate change, air pollution, ecosystem disruption, and biodiversity loss. This cross-scale perspective supports research on how organisms respond to altered environmental conditions. It also informs efforts to reduce emissions and protect biodiversity, linking biological evidence with broader environmental decision-making.
