Kinetics of Calcite Precipitation by Ureolytic Bacteria under Aerobic and Anaerobic Conditions
(2019-05)The kinetics of urea hydrolysis (ureolysis) and induced calcium carbonate (CaCO3) precipitation for engineering use in the subsurface was investigated under aerobic conditions using Sporosarcina pasteurii (ATCC strain ... -
Quorum sensing inhibition as a promising method to control biofilm growth in metalworking fluids
(2019-04)Microbial contamination in metalworking systems is a critical problem. This study determined the microbial communities in metalworking fluids (MWFs) from two machining shops and investigated the effect of quorum sensing ... -
Analysis of convective and diffusive transport in the brain interstitium
(2019-03)Background Despite advances in in vivo imaging and experimental techniques, the nature of transport mechanisms in the brain remain elusive. Mathematical modelling verified using available experimental data offers a powerful ... -
Glass Dynamics and Domain Size in a Solvent-Polymer Weak Gel Measured by Multidimensional Magnetic Resonance Relaxometry and Diffusometry
(2019-02)Nuclear magnetic resonance measurements of rotational and translational molecular dynamics are applied to characterize the nanoscale dynamic heterogeneity of a physically cross-linked solvent-polymer system above and below ... -
Dynamic processing of DOM: Insight from exometabolomics, fluorescence spectroscopy, and mass spectrometry
(2018-06)Dissolved organic matter (DOM) in freshwater environments is an important source of organic carbon, supporting bacterial respiration. Frozen environments cover vast expanses of our planet, with glaciers and ice-sheets ... -
Multiscale analysis of autotroph-heterotroph interactions in a high-temperature microbial community
(2018-09)Interactions among microbial community members can lead to emergent properties, such as enhanced productivity, stability, and robustness. Iron-oxide mats in acidic (pH 2–4), high-temperature (> 65 °C) springs of Yellowstone ... -
Light-Based 3D Printing of Hydrogels with High-Resolution Channels
(2019-01)Hydrogels are soft, water-based gels with widespread applications in personal care products, medicine and biomedical engineering. Many applications require structuring the hydrogel into complex three-dimensional (3D) shapes. ... -
Conversion of sugars and biomass to furans using heterogeneous catalysts in biphasic solvent systems
(2018-09)Within the last decade, interest in using biphasic systems for producing furans from biomass has grown significantly. Biphasic systems continuously extract furans into the organic phase, which prevents degradation reactions ... -
Self-paced, Active Problem-Solving Using Immediate Feedback (IF-AT; Scratch-off) Forms in Large Classes
(2018-05)In-class example problems that students work out on their own using active problem-solving are typically well received and help the students better learn the material; however, they are difficult to enact in large classes ... -
Microbial community changes during a toxic cyanobacterial bloom in an alkaline Hungarian lake
(2018-08)The Carpathian Basin is a lowland plain located mainly in Hungary. Due to the nature of the bedrock, alluvial deposits, and a bowl shape, many lakes and ponds of the area are characterized by high alkalinity. In this study, ... -
CD103 (aE integrin) undergoes endosomal trafficking in human dendritic cells, but does not mediate epithelial adhesion
(2018-12)Dendritic cell (DC) expression of CD103, the α subunit of αEβ7 integrin, is thought to enable DC interactions with E-cadherin-expressing gastrointestinal epithelia for improved mucosal immunosurveillance. In the stomach, ... -
Zosteric acid and salicylic acid bound to a low density polyethylene surface successfully control bacterial biofilm formation
(2018-04)The active moieties of the anti-biofilm natural compounds zosteric (ZA) and salicylic (SA) acids have been covalently immobilized on a low density polyethylene (LDPE) surface. The grafting procedure provided new non-toxic ... -
Phosphate starvation response controls genes required to synthesize the phosphate analog arsenate
(2018-05)Environmental arsenic poisoning affects roughly 200 million people worldwide. The toxicity and mobility of arsenic in the environment is significantly influenced by microbial redox reactions, with arsenite (AsIII ) being ... -
A large-scale multiomics analysis of wheat stem solidness and the wheat stem sawfly feeding response, and syntenic associations in barley, Brachypodium, and rice
(2018-02)The wheat stem sawfly (WSS), Cephus cinctus Norton (Hymenoptera: Cephidae), is an important pest of wheat and other cereals, threatening the quality and quantity of grain production. WSS larvae feed and develop inside the ... -
First characterization of a biphasic, switch-like DNA amplification
(2018-03)We report the first DNA amplification chemistry with switch-like characteristics: the chemistry is biphasic, with an expected initial phase followed by an unprecedented high gain burst of product oligonucleotide in a second ... -
