Effect of sulfate on low-temperature anaerobic digestion
Madden, Pádhraig; Al-Raei, Abdul M.; Enright, Anne M.; Chinalia, Fabio A.; de Beer, Dirk; O'Flaherty, Vincent; Collins, Gavin (Frontiers Media, 2014-07-24)The effect of sulfate addition on the stability of, and microbial community behavior in, low-temperature anaerobic expanded granular sludge bed-based bioreactors was investigated at 15 degrees C. Efficient bioreactor ... -
Emergence of instability-driven domains in soft stratified materials
Li, Jian; Slesarenko, Viacheslav; Rudykh, Stephan (Nature Research, 2022-05-02)Nature frequently employs the buckling phenomenon to facilitate the formation of complicated patterns across length-scales. Current knowledge, however, is limited to a small set of buckling-induced microstructure transformations ... -
Estimating average attributable fractions with confidence intervals for cohort and case control studies
Ferguson, John; Alvarez-Iglesias, Alberto; Newell, John; Hinde, John; O’Donnell, Martin (SAGE Publications, 2016-06-24)Chronic diseases tend to depend on a large number of risk factors, both environmental and genetic. Average attributable fractions were introduced by Eide and Gefeller as a way of partitioning overall disease burden into ... -
Instability-induced pattern formations in soft magnetoactive composites
Goshkoderia, Artemii; Chen, Vincent; Li, Jian; Juhl, Abigail; Buskohl, Philip; Rudykh, Stephan (American Physical Society, 2020-04-14)Elastic instabilities can trigger dramatic microstructure transformations giving rise to unusual behavior in soft matter. Motivated by this phenomenon, we study instability-induced pattern formations in soft magnetoactive ... -
Magnetic field-induced asymmetric mechanical metamaterials
Zhang, Quan; Cherkasov, Andrei V.; Arora, Nitesh; Hu, Gengkai; Rudykh, Stephan (Elsevier, 2023)We propose a magnetic field-induced asymmetric mechanical metamaterial. The tunable metamaterial integrates hard-Magnetic Active Elastomers (hMAEs) into the microstructural design combining snap-through, bi-stability, and ... -
Magneto-deformation and transverse elastic waves in hard-magnetic soft laminates
Zhang, Quan; Rudykh, Stephan (Elsevier, 2022-04-28)We study the magneto-mechanical behavior of periodic laminates made of hard-magnetic active elastomers (HMAEs). We formulate the amended free-energy function for HMAEs, and derive an explicit expression for the induced ... -
Mechanical instability tuning of a magnetorheological elastomer composite laminate
Chen, Vincent W.; Arora, Nitesh; Goshkoderia, Artemii; Willey, Carson L.; Turgut, Zafer; Buskohl, Philip R.; Rudykh, Stephan; Juhl, Abigail T. (Elsevier, 2022-12-28)Magnetorheological elastomers (MRE) can change their shape and properties when activated by an external magnetic field. The attractive tunable properties of this stimuli-responsive composite can be further amplified by ... -
Nonlinear elastic vector solitons in hard-magnetic soft mechanical metamaterials
Zhang, Quan; Cherkasov, Andrei V.; Xie, Chen; Arora, Nitesh; Rudykh, Stephan (Elsevier, 2023-07-14)We propose a design of a metamaterial for magnetically tunable propagation of nonlinear vector solitary waves. The metamaterial consists of a periodic array of units of hard-magnetic inclusion embedded in a soft matrix. ... -
Post-buckling development in soft particulate composites
Chen, Dean; Xiang, Yuhai; Arora, Nitesh; Yao, Qi; Li, Jian; Rudykh, Stephan (Elsevier, 2023-07-26)In this paper, we investigate the post-buckling development of instability-induced patterns in soft particulate composites. Upon reaching the critical strain level, the composite experiences microstructural buckling. ... -

(Frontiers Media, 2020-12-15)Production of volatile fatty acids (VFAs), fundamental building blocks for the chemical industry, depends on fossil fuels but organic waste is an emerging alternative substrate. Lactate produced from sugar-containing waste ... -
Structural and material electro-mechanical instabilities in microstructured dielectric elastomer plates
Bahreman, Marzieh; Arora, Nitesh; Darijani, Hossein; Rudykh, Stephan (Elsevier, 2022-02-18)In this paper, we investigate the stability of microstructured dielectric elastomer (DE) plates under electro-mechanical finite deformations.
