As the impact of COVID-19 on society became apparent, the engineering and scientific community recognized the need for innovative solutions. Two potential roadmaps emerged: developing short-term solutions to address the immediate needs of the healthcare communities and developing mid/long-term solutions to eliminate the over-arching threat. However, in a truly global effort, researchers from all backgrounds came together in tackling this challenge. Short-term efforts have focused on re-purposing ...

Raman lasers based on integrated silica whispering gallery mode resonant cavities have enabled numerous applications from telecommunications to biodetection.To overcome the intrinsically low Raman gain value of silica, these devices leverage their ultra-high quality factors (Q), allowing sub-mW stimulated Raman scattering (SRS) lasing thresholds to be achieved.A closely related nonlinear behavior to SRS is stimulated anti-Stokes Raman scattering (SARS).This nonlinear optical process combines the pump ...

Plasmonic nanomaterials and nanostructured substrates have made a significant impact in sensing and imaging due to their ability to improve optical field confinement at interfaces. This improved confinement increases the optical field intensity, enabling numerous nonlinear effects to be revealed. However, one challenge is effectively coupling light into and out of the plasmonic nanomaterial. One approach is to directly integrate the plasmonic nanomaterials onto the surface of light emitting optical ...

Many coal combustion by-products (CCBP's) such as fly ashes, fluidized bed combustion BP's, and flue gas desulfurization BP's (FGD-BP's) are produced when coal is burned for generation of electricity. Most of these CCBP's are disposed in landfills/surface impoundments, and interest has arisen in using these BP's on agricultural land, especially as an acid soil amendment. Leaf area per gram shoot dry matter yield (DMY) was relatively constant over all experiments and the mean value for plants grown ...

To identify the parts of retroviral integrase that interact with its DNA substrates, we compared the patterns of target site usage by chimeric enzymes and protein fragments in assays that reveal integrase's non-specific nuclease activities. The central region of 12 chimeric proteins between the human immunodeficiency virus type 1 and visna virus integrases was found to be responsible for selecting non-viral target DNA sites when small alcohols provide the attacking nucleophilic OH group during non- ...

Abstract Plants grown in acidic soil usually require relatively high amounts of available phosphorus (P) to optimize growth and productivity, and sources of available P are often added to meet these requirements. Phosphorus may also be made available at relatively high rates in native soil when roots are colonized with arbuscular mycorrhizal fungi (AMF). Addition of P to soil usually reduces root‐AMF colonization and decreases beneficial effects ofAMF to plants. In glasshouse experiments, soil treatments ...

Abstract Arbuscular mycorrhizal fungi (AMF) benefit plants by allowing them to grow and produce in relatively harsh mineral stress environments. This has been attributed extensively to ability of AMF to expand the volume of soil for which mineral nutrients are made available to plants compared to what roots themselves would contact. This article reviews the effects of AMF on enhancing/reducing acquisition of phosphorus (P), nitrogen (N), sulfur (S), boron (B), potassium (K), calcium (Ca), magnesium (Mg), ...

(switchgrass) was grown in pHCa 4 and 5 (soil:10 mM CaCl2, 1:1) soil (typic Hapludult) inoculated with eight isolates of AMF [Glomus (G.) clarum, G. diaphanum, G. etunicatum, G. intraradices, Gigaspora (Gi.) albida, Gi. margarita, Gi. rosea and Acaulospora (A.) morrowiae] to determine the effects of these isolates on plant growth and root colonization. Compared to nonmycorrhizal ( ...

To assess beneficial or detrimental plant growth effects when flue gas desulfurization by-products (FGD-BPs) are applied to acid soil, experiments were conducted in a greenhouse to determine growth of forages (orchardgrass, tall fescue, switchgrass, eastern gamagrass, white clover and alfalfa) on an acid pH 4.6 soil with different levels of three FGD-BPs and chemical-grade calcium carbonate (limestone), calcium sulfate and calcium sulfite. The FGD-BPs tested were high-CaSO4, high-CaSO4 enriched with ...

Abstract The large amounts of coal combustion by‐products (CCBs) generated by coal burning power plants must be utilized or discarded, and beneficial use of these materials are desired. One beneficial use of CCBs could be application to agricultural land. Information about the use of one kind of CCB (flue gas desulfurization by‐product, FGD‐BP) on soil is limited. Maize (Zea mays L.) was grown (greenhouse) on an acid soil [Umbric Dystrochrept, pHCa (1:1, soil: 10 mM CaCl2) 4.2] amended with two high CaSO4 ...

Acid soil‐ or aluminum (Al)‐tolerant plants offer considerable protection against soil acidity problems.
