Design of efficient block-sparse data structures and associated tensor multiplications for applications in Cluster in Molecule electronic structure calculations
(University of Waterloo, 2022-08-18)The Cluster-in-molecule approach (CiM) is one of the most popular methods in electronic structure calculations for medium to large molecules and systems. The Nooijen group is currently developing a new CiM approach using ... -
Interfacing fluorescent DNA oligonucleotides with graphene oxide and metal oxides: from adsorption to sensing
(University of Waterloo, 2022-08-18)DNA, apart from being the mode of genomic information storage, has found several uses in catalysis (DNAzymes) and target detection (aptamers). Developing novel biosensors utilizing these properties has therefore been a ... -
Cellular Inclusion Bodies: Structure and Mechanisms
(University of Waterloo, 2022-08-18)Inclusion bodies (IBs) are insoluble aggregate structures that commonly form upon overexpression of proteins in heterologous hosts with relevance to biomedicine and biotechnology. These structures are of broad interest in ... -
Structural characterization and engineering of Adnectin inclusion bodies
(University of Waterloo, 2022-08-15)Protein aggregation is a fundamental process occurring as a response to aging, disease, protein overexpression and in many areas of biotechnology and medical applications. There has been much recent progress in determining ... -
Multiscale Modelling of Structural Transformation in Metal Nanocatalysts for CO2 Electroreduction
(University of Waterloo, 2022-08-12)The precise control of nanostructure and surface atomic arrangement can be used to tune the electrocatalytic properties of materials and improve their performance. Unfortunately, the long-term structural stability of ... -
The Reproductive Effects of Municipal Wastewater Effluents
(University of Guelph, 2017-03-01)There is a growing concern that pharmaceuticals and other chemicals present in the effluents (sewage discharged into a river) from municipal wastewater treatment plants enter the aquatic environment, where they may affect ... -
An Assessment of the Spatial and Temporal Variability of Biological Responses to Municipal Wastewater Effluent in Rainbow Darter (Etheostoma caeruleum) Collected along an Urban Gradient
(PLOS, 2016-10-24)Municipal wastewater effluent (MWWE) and its constituents, such as chemicals of emerging concern, pose a potential threat to the sustainability of fish populations by disrupting key endocrine functions in aquatic organisms. ... -
Characterizing Transcriptional Networks in Male Rainbow Darter (Etheostoma caeruleum) that Regulate Testis Development over a Complete Reproductive Cycle
(PLOS, 2016-11-18)Intersex is a condition that has been associated with exposure to sewage effluents in male rainbow darter (Etheostoma caeruleum). To better understand changes in the transcriptome that are associated with intersex, we ... -
Rainbow trout exposed to benzo[a]pyrene yields conserved microRNA binding sites in DNA methyltransferases across 500 million years of evolution
(Springer, 2017-12-04)The objective of this study was to examine the regulation of DNA methylation following acute (24 h) and prolonged (14 d) exposure to low (1 ng/L) and high (10 ng/L) benzo[a]pyrene. However, with the recent release of the ... -
Use of prospective and retrospective risk assessment methods that simplify chemical mixtures associated with treated domestic wastewater discharges
(Wiley, 2018-03-01)A framework is presented that is intended to facilitate the evaluation of potential aquatic ecological risks resulting from discharges of down-the-drain chemicals. A scenario is presented using representatives of many of ... -
Tissue storage affects lipidome profiling in comparison to in vivo microsampling approach
