Electrical resistivity tomography (ERT) is a subsurface imaging geophysical technique. Traditional ERT inversion methods, such as smoothness-constrained least-squares approaches, often suffer from discretization artifacts when reconstructing electrical resistivity from resistance measurements. To address the limitations of conventional ERT inversion, this study introduces…

Dedicated energy crops are promising feedstocks to make biofuels including jet fuels. This study applies life cycle analysis (LCA) to estimate direct well-to-wake (WTW) greenhouse gas (GHG) emissions (g CO2e/MJ) for jet fuel derived from five energy crops—biomass sorghum, miscanthus, switchgrass, poplar, and willow—via Fischer–Tropsch-to-Jet (FTJ) and Ethanol-to-Jet (ETJ)…

Graphene oxide (GO) membranes have garnered significant attention for their unique structural and functional properties, particularly in applications involving aqueous environments. This study explores the reduction of GO using natural sunlight, highlighting its distinct advantages over conventional reduction methods. Sunlight-induced reduction facilitates water removal, r…

The practical application of graphene oxide (GO) in flexible energy storage is often hindered by its inherent mechanical fragility and poor stability in aqueous environments. In this study, we demonstrate that controlled simulated sunlight irradiation transforms GO membranes into robust, high-performance dielectric separators through a surface-selective modification proces…

Digital twins (DTs) that can predict the transient behaviour of a water treatment plant combined with buffer capacity, enable reductions in specific energy consumption (SEC) in response to time-of-use (TOU) electricity costs. The accuracy of a DT depends on the richness of its training data (Conejos Fuertes et al. 2020). However, process changes cannot easily be tested in…

The use of recycled or scrap or secondary aluminum to manufacture high pressure die castings (HPDC) for structural applications is an opportunity to reduce cost, energy expenditure and emission of greenhouse gases. Technical challenges that must be overcome to achieve this on a large scale include scrap sorting and availability of alloys that can take such feedstock while…

Excitons—elementary excitations formed by bound electron–hole pairs—govern the optical properties and excited-state dynamics of materials. In two dimensions, excitons are theoretically predicted to have a linear energy–momentum relation with a non-analytic discontinuity in the long wavelength limit, which mimics the dispersion of a photon. This results in an exciton with a…

Meeting the US Sustainable Aviation Fuel Grand Challenge target of 35 billion gal annually by 2050 will require an estimated 380 million–700 million dry tons of agricultural biomass feedstock. This study evaluates the implications of large-scale biomass production for land use, crop production, and market outcomes under mature market conditions. Results suggest that produc…

Biological nitrogen (N) fixation (BNF) provides the N needed to produce proteins and other biological building blocks, helping feed humanity and mitigate climate change. Due to its high energetic cost compared to other forms of N acquisition, biotic investment in BNF indicates N limitation. Globally gridded BNF flux data provide an opportunity to determine the energetic in…
