Microbial communities are predominantly found in biofilms, which are composed of extracellular polymeric substances (EPS). The EPS matrix is engineered and reconfigured by microbes, making it difficult to distinguish between the biotic and abiotic origins of biofilm properties. To establish this distinction, simplify models of the EPS matrix, the study uses molecular dynamic(MD) simulation to predict the nanoscale structure of a model extracellular polymeric substance (EPS) matrix and its sensitivity to interpolymer interactions and water content.

Control of molecular orientation and alignment has been a longstanding goal in chemical reaction dynamics because the outcome of chemical reactions inherently depends on the relative orientation of the colliding species.

Wildland fires contribute significantly to the total carbonaceous aerosol mass concentration in the troposphere. These aerosols, formed from the combustion of biomass fuels, exhibit strong absorption and scattering of visible light, which impacts the radiative forcing in the troposphere. The Georgia Wildland-fire Simulation Experiment (G-WISE), conducted in Athens, GA during October-November 2022, was designed to develop a scientific basis for the regulations that dictate under what conditions a prescribed burn can be performed.

Egyptian blue is considered the first synthetic pigment, dating back to the 3rd millennium BC¹. It is a layered calcium copper silicate material with the chemical composition CaCuSi₄O₁₀. Later, a related family of these layered silicates were discovered— Han blue (BaCuSi₄O₁₀), and Han Purple (BaCuSi₂O₆)².

In 2020, Greaves et al. concluded from two independent data sources that phosphine is present in the cloud decks of Venus. Their study focused on the fundamental first rotational transition (J = 1-0) of PH₃ and their detection of phosphine is solely based on this single transition. Given the importance of phosphine as a possible biosignature and our current understanding of the chemistry of Venus, multiple studies reanalyzed the data of Greaves et al.

Pyrogenic organic matter (PyOM, aka ‘black carbon’) generated via the incomplete combustion of biomass or fossil fuels is an important component in soil, atmospheric, sedimentary, and aquatic environments. In particular, the condensed aromatic compounds (ConAC) in PyOM are slow-cycling rendering them important to global carbon cycles and the sequestration of carbon in soils.

The functional role of a biological molecule hinges on its unique structure. The context by which structure impacts function is a vital piece of information that can provide insight into underlying biological processes. One set of biological molecules that have received renewed interest for their biological significance and potential role as markers of cellular dysfunction are lipids.

The Center for Applied Isotope Studies (CAIS) is a multidisciplinary scientific research unit and core service facility within the UGA Office of Research that specializes in the quantification of isotope ratios using mass spectrometry.

Significant scientific attention has been spent on the elucidation of protein’s structure to explain its function. Lots of proteins stay around cell membrane or vesicles to facilitate cellular metabolism. These proteins usually form monolayer structure around cell membrane/vesicles and therefore cause challenges for the measurements of X-ray crystallography and NMR, which cannot provide high resolution results for proteins in monolayer.
