The electrochemical instability of ether-based electrolyte solutions hinders their practical applications in high-voltage Li metal batteries. To circumvent this issue, here, we propose a dilution strategy to lose the Li+/solvent interaction and use the dilute non-aqueous electrolyte solution in high-voltage lithium metal batteries. We demonstrate that in a non-polar dipropyl ether (DPE)-based electrolyte solution with lithium bis(fluorosulfonyl) imide salt, the decomposition order of solvated species can be adjusted to promote the Li+/salt-derived anion clusters decomposition over free ether solvent molecules. This selective mechanism favors the formation of a robust cathode electrolyte interphase (CEI) and a solvent-deficient electric double-layer structure at …

Form Cdc14 Phosphatase Contributes To Cell Wall Integrity And Pathogenesis In Candida Albicans, Kedric L. Milholland, Ahmed Abdelkhalek, Kortany M. Baker, Smriti Hoda, Andrew G. Demarco, Noelle H. Naughton, Angela N. Koeberlein, Gabrielle R. Lorenz, Kartikan Anandasothy, Antonio Esperilla-Muñoz, Sanjeev K K. Narayanan, Jaime Correa-Bordes, Scott D. Briggs, Mark C. Hall

The Cdc14 phosphatase family is highly conserved in fungi. In Saccharomyces cerevisiae, Cdc14 is essential for down-regulation of cyclin-dependent kinase activity at mitotic exit. However, this essential function is not broadly conserved and requires only a small fraction of normal Cdc14 activity. Here, we identified an invariant motif in the disordered C-terminal tail of fungal Cdc14 enzymes that is required for full enzyme activity. Mutation of this motif reduced Cdc14 catalytic rate and provided a tool for studying the biological significance of high Cdc14 activity. A S. cerevisiae strain expressing the reduced-activity hypomorphic mutant allele (cdc14hm ) as the …

Combating The Hydra: Violence And Resistance In The Habsburg Empire, 1500–1900, Stephan Steiner

Central European Studies

Combating the Hydra explores structural as well as occasion-specific state violence committed by the early modern Habsburg Empire. The book depicts and analyzes attacks on marginalized people “maladjusted” of all sorts, women “of ill repute,” “heretic” Protestants, and “Gypsies.” Previously uncharted archival records reveal the use of arbitrary imprisonment, coerced labor, and deportation. The case studies presented provide insights into the origins of modern state power from varied techniques of population control, but are also an investigation of resistance against oppression, persecution, and life-threatening assaults. The spectrum of fights against debasement is a touching attestation of the humanity of the …

Incentive Mechanisms To Exploit Intraseasonal Price Arbitrage Opportunities For Smallholder Farmers: Experimental Evidence From Malawi, Tabitha Nindi, Jacob Ricker-Gilbert, Jonathan Bauchet

Department of Agricultural Economics Faculty Publications

Seasonal commodity price fluctuations can potentially offer farmers arbitrage opportunities to increase their income. However, smallholder farmers in most of sub-Saharan Africa often do not exploit these opportunities to the fullest extent possible. To inform this issue, we conducted a randomized controlled trial among 1739 smallholder farmers in Malawi to estimate the impact of two key post-harvest constraints, lack of appropriate storage technology and commitment issues, on farmers' legume storage and sales decisions. The treated groups received (i) an improved storage technology in the form of two hermetic (airtight) bags, (ii) the same improved storage technology under the condition that …

The Nazis, The Vatican, And The Jews Of Rome, Patrick J. Gallo

Purdue University Press Books

On October 16, 1943, the Jews of Rome were targeted for arrest and deportation. The Nazis, the Vatican, and the Jews of Rome examines why—and more importantly how—it could have been avoided, featuring new evidence and insight into the Vatican’s involvement. At the time, Rome was within reach of the Allies, but the overwhelming force of the Wehrmacht, Gestapo, and SS in Rome precluded direct confrontation. Moral condemnations would not have worked, nor would direct confrontation by the Italians, Jewish leadership, or even the Vatican.

Gallo underscores the necessity of determining what courses of actions most likely would have spared …

Electro- And Photoactivation Of Silver–Iron Oxide Particles As Magnetically Recyclable Catalysts For Cross-Coupling Reactions, Qi Wang, Zhongxia Shang, Haiyan Wang, Alexander Wei

Department of Chemistry Faculty Publications

Colloidal Ag particles decorated with Fe3O4 islands can be electrochemically or photochemically activated as inverse catalysts for C(sp2)–H heteroarylation. The silver–iron oxide (SIO) particles are reduced into redox-active forms by cathodic charging at mild potentials or by short-term light exposure, and can be reused multiple times by magnetic cycling without further activation. A negative shift in the reduction peak is attributed to an overpotential produced by surface Fe3O4 which separates residual Ag ions or clusters from bulk silver. The catalytic efficiency of SIO is maintained even with acid degradation, which can be countered simply by adding water to the reaction …

Covid-19 As A Magnifying Glass: Exploring The Importance Of Relationships As Education Students Learn And Teach Robotics Via Zoom, Jennifer Kidd, Krishnanand Kaipa, Kristie Gutierrez, Min Jung Lee, Pilar Pazos, Stacie I. Ringleb

Journal of Pre-College Engineering Education Research (J-PEER)

Ed+gineering, an NSF-funded program, adapted hands-on robotics instruction for online delivery in response to the COVID-19 pandemic. This qualitative multiple case study shares the experiences of participating education students in spring 2021 as they collaborated virtually with engineering students and fifth graders to engineer bioinspired robots in an afterschool technology club adapted to be virtual. The online context reduced the education students’ interactions with people other than the engineering students and fifth graders on their team and thus positioned COVID-19 as a metaphorical magnifying glass amplifying the critical role that these relationships played in influencing the project’s outcomes. Through analyzing …

Draft Genome Assemblies Of The Avian Louse Brueelia Nebulosa And Its Associates Using Long-Read Sequencing From An Individual Specimen, Andrew D. Sweet, Daniel R. Browne, Alvaro G. Hernandez, Kevin P. Johnson, Stephen L. Cameron

Purdue University Libraries Open Access Publishing Fund

Sequencing high molecular weight (HMW) DNA with long-read and linked-read technologies has promoted a major increase in more complete genome sequences for nonmodel organisms. Sequencing approaches that rely on HMW DNA have been limited to larger organisms or pools of multiple individuals, but recent advances have allowed for sequencing from individuals of small-bodied organisms. Here, we use HMW DNA sequencing with PacBio long reads and TELL-Seq linked reads to assemble and annotate the genome from a single individual feather louse (Brueelia nebulosa) from a European Starling (Sturnus vulgaris). We assembled a genome with a relatively high …

From In-Person To Virtual: A Case Study Of An Animal-Assisted Visiting Program In A Pediatric Setting, Whitney Romine

People and Animals: The International Journal of Research and Practice

This article focuses on the practical aspects of converting a successful in-person AAA program to a virtual program in a health care setting including human, canine, and physical resources; animal welfare considerations; training, infection control, and safety guidelines; and visit delivery procedures. In 1992, an interdisciplinary team at Akron Children’s Hospital founded the Doggie Brigade, an animal-assisted activities (AAA) program where volunteer therapy dogs and their handlers visit pediatric patients. The program has become a cornerstone of the hospital’s culture over its now 30-year tenure. In March 2020, the announcement of the COVID-19 pandemic forced health care organizations to suspend …

Matrix-Entrapped Fibers Create Ecological Niches For Gut Bacterial Growth, Nuseybe Bulut, Thaisa M. Cantu-Jungles, Xiaowei Zhang, Zeynep Mutlu, Mukerrem Cakmak, Bruce R. Hamaker

Purdue University Libraries Open Access Publishing Fund

Insoluble plant cell walls are a main source of dietary fiber. Both chemical and physical fiber structures create distinct niches for gut bacterial utilization. Here, we have taken key fermentable solubilized polysaccharides of plant cell walls and fabricated them back into cell wall-like film forms to understand how fiber physical structure directs gut bacterial fermentation outcomes. Solubilized corn bran arabinoxylan (Cax), extracted to retain some ferulate residues, was covalently linked using laccase to form an insoluble cell wall-like film (Cax-F) that was further embedded with pectin (CaxP-F). In vitro fecal fermentation using gut microbiota from three donors was performed on …

Measuring Religiosity Of East Asians: Multiple Religious Belonging, Believing, And Practicing, Fenggang Yang, Brian Mcphail

Department of Sociology Faculty Publications

Social surveys normally assume that respondents adhere to a single religious faith in belonging, believing, and practicing congruently. Some surveys even take religious identity as the singular measure of religiosity and examine its relationship with other variables. This practice, however, fails to capture nonexclusive and hybrid religiosity, which is arguably the traditional and normal pattern in East Asia while becoming increasingly common in the West. We have developed a new set of survey questions and conducted a survey among East Asian international students at an American university. The findings show that multiple religious belonging, believing, and practicing are quite common, …

Interactions Between Humans And Dogs During The Covid-19 Pandemic: Recent Updates And Future Perspectives, Mohamed S. Kamel, Amr A. El-Sayed, Rachel A. Munds, Mohit S. Verma

Purdue University Libraries Open Access Publishing Fund

COVID-19 is one of the deadliest epidemics. This pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but the role of dogs in spreading the disease in human society is poorly understood. This review sheds light on the limited susceptibility of dogs to COVID-19 infections which is likely attributed to the relatively low levels of angiotensin-converting enzyme 2 (ACE2) in the respiratory tract and the phylogenetic distance of ACE2 in dogs from the human ACE2 receptor. The low levels of ACE2 affect the binding affinity between spike and ACE2 proteins resulting in it being uncommon for dogs to …

The Impact Of Girl Scout Engineering Experiences On The Identity Development Of Middle Schoolers, Abigail M. Clark, Rachel Kajfez

Journal of Pre-College Engineering Education Research (J-PEER)

Despite years of recruitment efforts, women remain significantly underrepresented throughout engineering. While research into precollege engineering education has expanded, it has primarily focused on formal learning settings, even though students spend significantly more time outside of the classroom. The COVID-19 pandemic changed everything, including the time spent outside of the classroom in informal environments. Specifically, programs had to evolve to provide online content and at-home activities. Some programs even shut down completely. Within this context, our study sought to understand the impact of one informal engineering learning experience, a Girl Scout engineering badge, which also shifted online due to the …

Abrupt Shift Or Caught Off Guard: A Systematic Review Of K-12 Engineering And Stem Education’S Response To The Covid-19 Pandemic, Ibrahim Delen, Tugba Yuksel

Journal of Pre-College Engineering Education Research (J-PEER)

In the past hundred years, there have been a number of pandemics that have affected the entire world, including the 1918 H1N1 influenza pandemic, the 1957 H2N2 influenza pandemic, and the 2009 H1N1 influenza pandemic. While responses to the most recent H1N1 influenza pandemic remained local, the COVID-19 pandemic, on the other hand, resulted in long-term school closures all around the world, prompting a sudden shift to distant education by compelling K-12 educators and students to do so. The purpose of this study is to find out how K-12 education studies reacted to the sudden shift in supporting engineering and …

Additive And Synergistic Relations Of Early Mother–Child And Caregiver–Child Interactions And Socioeconomic Outcomes In Adulthood, Robert Duncan, Inga Nordgren, Sara A. Schmitt, Deborah Lowe Vandell

Purdue Center for Early Learning Faculty and Staff Publications

Prior theoretical and empirical studies have linked the first 3 years of children's life with later life outcomes. One primary explanation is the critical role these experiences play in children's early brain development (including their early language and cognitive abilities) and subsequent schooling achievement. The current study is a registered report with two complementary research objectives: (1) examine to what extent stimulating and responsive interactions with mothers and nonparental caregivers during the first 3 years of life show additive or synergistic associations with key socioeconomic outcomes in adulthood (i.e., educational attainment, salary, and employment status), and (2) examine to what …
