Comparing Urban Citizenship, Sanctuary Cities, Local Bureaucratic Membership, and Regularizations

open access: yesPAR. Public Administration Review, 2019
Irregular migrants tend to live in dense urban settings. Cities respond to this phenomenon with a variety of urban immigration and citizenship policies in support of irregular migrants. These urban policies produce a disparity between local inclusion and

Chemical Doping Engineering of Polarization and Topological Textures in van der Waals Ferroelectric CuInP2S6

open access: yesAdvanced Science, EarlyView.
Our work reports that Li⁺ doping in CuInP2S₆ induces coexistence of high‐ and low‐polarization states, which fosters a rich spectrum of topological polar textures, such as bubbles and labyrinth domains. An unconventional flexoelectric effect is also discovered, where strain gradients can mechanically manipulate these polarization states and their ...

Ion Crowding Effect in Unilaterally Downsized Perovskite Memristors

open access: yesAdvanced Science, EarlyView.
The downscaling of perovskite memristors incorporating monocrystalline nanoplates is accompanied by an ion crowding effect, which greatly enhances the local electric field in the vicinity of electrode. The highly controlled crowding of anions and vacancies results in anisotropic switching characteristics as well as unique morphology modification ...

Scalable Upcycling of Spent Lithium‐Ion Battery Anodic Graphite to Electronic‐Grade Graphene

open access: yesAdvanced Science, EarlyView.
Graphite anodes from spent lithium‐ion batteries are upcycled into electronic‐grade graphene nanoplatelets for highly conductive screen printing inks (> 104 S m−1). Screen‐printed micro‐supercapacitors confirm the utility of the upcycled graphene (1.78 mF/cm2 capacitance for > 10 000 cycles). Life cycle assessment and techno‐economic analysis highlight

‘From Sanctuary to Welcoming Cities’: Negotiating the Social Inclusion of Undocumented Migrants in Liège, Belgium

open access: yes, 2019
Cities have become important sites of sanctuary for migrants with a precarious legal status. While many national governments in Europe have adopted restrictive immigration policies, urban governments have undertaken measures to safeguard undocumented ...

Good Sanctuary Doctoring for Undocumented Patients.

open access: yesAMA journal of ethics, 2019
Clinicians whose practice includes a significant immigrant population report a climate of fear adversely affecting their current patients. Increased immigration enforcement targeting undocumented immigrants increases these patients' stress and negatively

Gate‐Dielectric Surface Engineering With Fluorinated Monolayers: Minimizing Contact Resistance and Nonidealities in OFETs

open access: yesAdvanced Electronic Materials, EarlyView.
Surface engineering of gate dielectrics with fluorinated self–assembled monolayers significantly improves the performance of organic field–effect transistors. In this study, Al2O3 functionalized with fluorinated phosphonic acids reduces contact resistance and hysteresis while achieving near‐zero threshold voltages, offering an alternative to ...

Foreign labor, peer‐networking and agricultural efficiency in the Italian dairy sector

open access: yesAgribusiness, EarlyView.
Abstract While the presence of immigrants in the agricultural sector is widely acknowledged, the empirical evidence on its economic consequences is lacking, especially from a microeconomic perspective. Using the Farm Accountancy Data Network panel data for Italian dairy farms in the period 2008–2018, the present study investigates the relationship ...
