Attempts To Measure Nanosecond Resolved Electronic Dynamics Of Charge Density Wave Phase Transition In 1t-Tas2, Ben Campbell

Honors Theses and Capstones

Scanning tunneling microscopes allow for atomic spatial resolution but the resulting images are necessarily time-averaged and fast dynamics are lost. Pump-probe spectroscopy is a common optical technique used to measure ultrafast electronic dynamics but the integration of optical pump-probe spectroscopy into an STM requires specialized knowledge and equipment. Alternatively, an all-electronic pump-probe spectroscopy technique has recently been developed for use with an STM that replaces the laser pulses of optical pump-probe with voltage pulses. In this paper, I implemented an all-electronic pump-probe scheme into an existing scanning tunneling microscope using an arbitrary waveform generator and a lock-in amplifier. I developed …

Access To Evidence In Private International Law, Francesco Parisi, Daniel Pi, Alice Guerra

Law Faculty Scholarship

This Article analyzes the interaction between the burden of proof and evidentiary discovery rules. Both sets of rules can affect incentives for prospective injurers to invest in evidence technology (i.e., ex ante investments that increase the quantity and quality of evidence in case an accident occurs). This interaction becomes acutely important in the private international law setting, where jurisdictions are split on the question whether the burden of proof should be treated as a substantive or procedural matter. When a tort occurs in Europe, but the case is litigated in American courts, treating the burden of proof as a procedural …

Data Supporting Effects Of Uv-C Disinfection On N95 And Kn95 Filtering Facepiece Respirator Reuse, Castine A. Bernardy, James Malley

Data Catalog

UV is a proven decontamination tool for microbial pathogens, including the SARS-CoV-2 virus. Lower log inactivation was observed on FFRs than would have been predicted by aqueous-based UV dose-response data for MS-2 bacteriophage and E. coli. Results have demonstrated that FFR materials yield varying results in terms of effective disinfection in experiments conducted on KN95 and N95 face respirators. The highest inactivation for both surrogates was observed with respirator KN95 B. The respirator yielded 3 and 2.75 log inactivation for E. coli and MS-2, respectively at UV doses of 1500 mJ/cm². KN95 A yielded the lowest …

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 …

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

Carsey Publications

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. …

A Semantically Enriched Taxonomic Revision Of Gryonoides Dodd, 1920 (Hymenoptera, Scelionidae), With A Review Of The Hosts Of Teleasinae, István Mikó, Lubomir Masner, Jonah M. Ulmer, Monique Raymond, Julia Hobbie, Sergei Tarasov, Cecilia Beatriz Margaría, Katja C. Seltmann, Elijah J. Talamas

Faculty Publications

Teleasinae are commonly collected scelionids that are the only known egg parasitoids of carabid beetles and therefore play a crucial role in shaping carabid populations in natural and agricultural ecosystems. We review the available host information of Teleasinae, report a new host record, and revise Gryonoides Dodd, 1920, a morphologically distinct teleasine genus. We review the generic concept of Gryonoides and provide diagnoses and descriptions of thirteen Gryonoides species and two varieties: G. glabriceps Dodd, 1920, G. pulchellus Dodd, 1920 (= G. doddi Ogloblin, 1967, syn. nov. and G. pulchricornis Ogloblin, 1967, syn. nov.), G. brasiliensis Masner & Mikó, sp. …

Democrats Sour On Sununu As Nh Governor's Approval Continues To Decline 12/22/2021, Unh Survey Center

All UNH Survey Center Polls

After enjoying widespread popularity throughout much of his tenure as governor, only a slim majority currently approve of Governor Chris Sununu's job performance. Much of this decline is due to a sizeable drop in support among Democrats. With Sununu having chosen not to run for the U.S. Senate in 2022, several individuals have been mentioned as candidates for the Republican nomination, but many are not well-known or well-liked in the state. A record low believe the state is headed in the right direction.

Approval Among Democrats Fuels Uptick In Biden Approval In Granite State 12/21/2021, Unh Survey Center

All UNH Survey Center Polls

President Joe Biden's approval rating has improved slightly, with state residents now evenly divided in their assessment of his job performance. Biden's approval among Democrats, which had declined for months, now matches marks from earlier in his presidency. Slim majorities disapprove of Biden's handling of foreign affairs and the economy, but a small majority approve of his handling of COVID-19. Only a quarter of Granite Staters feel the country is headed in the right direction.

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

Carsey Publications

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 …
