Childcare Remains Out Of Reach For Millions In 2021, Leading To Disproportionate Job Losses For Black, Hispanic, And Low-Income Families, Jonathan Koltai, Jessica A. Carson, Tyrus Parker, Rebecca Glauber

Carsey School of Public Policy

Using data from the U.S. Census Bureau’s Household Pulse Survey, collected in late summer through the fall of 2021, this brief documents recent racial and income disparities in reports of inadequate access to childcare and identifies the employment-related consequences of these shortages.

The authors find that, in Fall 2021, about 5 million U.S. households had a child under age 12 who was unable to attend childcare as a result of it being closed, unavailable, unaffordable, or because parents were concerned about their child’s safety in the past month. Black and low-income households were more likely to experience inadequate childcare access. …

Splashing Of Large Helium Nanodroplets Upon Surface Collisions, Paul Martini, Simon Albertini, Felix Laimer, Miriam Meyer, Michael Gatchell, Olof E. Echt, Fabio Zappa, Paul Scheier

Faculty Publications

In the present work we observe that helium nanodroplets colliding with surfaces can exhibit splashing in a way that is analogous to classical liquids. We use transmission electron microscopy and mass spectrometry to demonstrate that neutral and ionic dopants embedded in the droplets are efficiently backscattered in such events. High abundances of weakly bound He-tagged ions of both polarities indicate a gentle extraction mechanism of these ions from the droplets upon collision with a solid surface. This backscattering process is observed for dopant particles with masses up to 400 kilodaltons, indicating an unexpected mechanism that effectively lowers deposition rates of …

Smallest U.S. Population Growth In History: More Deaths, Fewer Births, And Less Immigration, Kenneth M. Johnson

Carsey School of Public Policy

In this brief, author Kenneth Johnson reports that the U.S. population grew by just 393,000 between July of 2020 and July of 2021 according to new Census Bureau estimates—the lowest rate of annual population gain in history and the smallest numeric gain in more than 100 years. Diminished immigration from abroad contributed, but the driver of this minimal population gain was that there were only 148,000 more births than deaths. This is the smallest natural gain in more than 80 years. COVID-19 played a central role in this small population gain. In addition to 475,000 deaths directly attributable to COVID-19 …

3d Bio-Printability Of Hybrid Pre-Crosslinked Hydrogels, Cartwright Nelson, Slesha Tuladhar, Loren Launen, Ahasan Habib

New Hampshire EPSCoR

Maintaining shape fidelity of 3D bio-printed scaffolds with soft biomaterials is an ongoing challenge. Here, a rheological investigation focusing on identifying useful physical and mechanical properties directly related to the geometric fidelity of 3D bio-printed scaffolds is presented. To ensure during- and post-printing shape fidelity of the scaffolds, various percentages of Carboxymethyl Cellulose (CMC) (viscosity enhancer) and different calcium salts (CaCl2 and CaSO4, physical cross-linkers) were mixed into alginate before extrusion to realize shape fidelity. The overall solid content of Alginate-Carboxymethyl Cellulose (CMC) was limited to 6%. A set of rheological tests, e.g., flow curves, amplitude tests, and three interval …

Probing Secondary Coordination Sphere Interactions Within Porphyrin-Cored Polymer Nanoparticles, Brian F. Patenaude, Erik B. Berda, Samuel Pazincni

New Hampshire EPSCoR

A suite of zinc porphyrin-cored random coil polymers and polymeric nanoparticles with varying degrees of potential hydrogen bonding character and steric bulk were synthesized and characterized to study secondary coordination sphere interactions. The reaction of cyanide with N,N-dimethylformamide in the presence of porphyrin-cored polymeric nanoparticles was monitored via UV-Vis spectroscopy. It is shown that the zinc porphyrin-cored polymers and nanoparticles catalyzed the reaction of cyanide with N,N-dimethylformamide with the highest reaction rates occurring with polymeric nanoparticles with a greater number of potential hydrogen bond donors and greater steric bulk.

Conductive Stimuli-Responsive Coordination Network Linked With Bismuth For Chemiresistive Gas Sensing, Aylin Aykanat, Christopher G. Jones, Evan Cline, Robert M. Stolz, Zheng Meng, Hosea M. Nelson, Katherine A. Mirica

New Hampshire EPSCoR

This paper describes the design, synthesis, characterization, and performance of a novel semiconductive crystalline coordination network, synthesized using 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP) ligands interconnected with bismuth ions, toward chemiresistive gas sensing. Bi(HHTP) exhibits two distinct structures upon hydration and dehydration of the pores within the network, Bi(HHTP)-α and Bi(HHTP)-β, respectively, both with unprecedented network topology (2,3-c and 3,4,4,5-c nodal net stoichiometry, respectively) and unique corrugated coordination geometries of HHTP molecules held together by bismuth ions, as revealed by a crystal structure resolved via microelectron diffraction (MicroED) (1.00 Å resolution). Good electrical conductivity (5.3 × 10–3 S·cm–1) promotes the utility of this material …

Fungal Community And Functional Responses To Soil Warming Are Greater Than For Soil Nitrogen Enrichment, Mark A. Anthony, Melissa A. Knorr, Jessica A. M. Moore, M. Simpson, Serita D. Frey

Faculty Publications

Soil fungi are key regulators of forest carbon cycling and their responses to global change have effects that ripple throughout ecosystems. Global changes are expected to push many fungi beyond their environmental niches, but there are relatively few studies involving multiple, simultaneous global change factors. Here, we studied soil fungal diversity, community composition, co-occurrence patterns, and decomposition gene responses to 10 years of soil warming and nitrogen addition, alone and in combination. We specifically examined whether there were fungal community characteristics that could explain changes in soil carbon storage and organic matter chemistry in chronically warmed and fertilized soil. We …

Accurate fire emissions inventories are crucial to predict the impacts of wildland fires on air quality and atmospheric composition. Two traditional approaches are widely used to calculate fire emissions: a satellite-based top-down approach and a fuels-based bottom-up approach. However, these methods often considerably disagree on the amount of particulate mass emitted from fires. Previously available observational datasets tended to be sparse, and lacked the statistics needed to resolve these methodological discrepancies. Here, we leverage the extensive and comprehensive airborne in situ and remote sensing measurements of smoke plumes from the recent Fire Influence on Regional to Global Environments and Air …
