Just Housing
Authors: Dawkins Casey J. 
Published: August 2021

A new conception of housing justice grounded in moral principles that appeal to the home's special connection to American life.
In response to the twin crises of homelessness and housing insecurity, an emerging “housing justice” coalition argues that America's apparent inability to provide decent housing for all is a moral failing. Yet if housing is a right, as housing justice advocates contend, what is the content of that right? In a wide-ranging examination of these issues, Casey Dawkins chronicles the concept of housing justice, investigates the moral foundations of the US housing reform tradition, and proposes a new conception of housing justice that is grounded in moral principles that appeal to the home's special connection to American life.
Dawkins examines the conceptual foundations of justice and explores the social meaning of the American home. He chronicles the evolution of American housing reform, showing how housing policy was pieced together from layers of housing and land-use policies enacted over time, and investigates the endurance—from the founding of the republic through the postwar era—of the owned single-family home as the embodiment of national values. Finally, Dawkins considers housing justice, drawing on elements of liberalism, republicanism, progressivism, and pragmatism to defend a right-based conception of housing justice grounded in the ideal of civil equality. Arguing that any defense of private property must appeal to the interests of those whose tenure is made insecure by the institution of private property, he proposes a “secure tenure” property regime and a “negative housing tax” that would fund a guaranteed housing allowance.
Exploring private land conservation non-adopters’ attendance at outreach events in the Chesapeake Bay watershed, USA

Published: August 2021

Background
Outreach events such as trainings, demonstrations, and workshops are important opportunities for encouraging private land operators to adopt voluntary conservation practices. However, the ability to understand the effectiveness of such events at influencing conservation behavior is confounded by the likelihood that attendees are already interested in conservation and may already be adopters. Understanding characteristics of events that draw non-adopters can aid in designing events and messaging that are better able to reach beyond those already interested in conservation.

Methods
For this study, we interviewed 101 operators of private agricultural lands in Maryland, USA, and used descriptive statistics and qualitative comparative analysis to investigate differences between the kinds of outreach events that adopters and non-adopters attended.

Results
Our results suggested that non-adopters, as compared to adopters, attended events that provided production-relevant information and were logistically easy to attend. Further, non-adopters were more selective when reading advertisements, generally preferring simplicity. Future research and outreach can build on these findings by experimentally testing the effectiveness of messages that are simple and relevant to farmers’ production priorities.

Background: Alopecia areata (AA) is a non-scaring alopecia which can affect any body hairy area. Excimer light 308 nm is a UVB irradiation with immunosuppressive effects. Low level light therapy (LLLT) emits low energy visible and infrared irradiation to modulate biological processes in cell. This study aimed to evaluate efficacy and safety of excimer light 308 nm versus LLLT in treatment of AA.
Methods: Thirty patients with multilocular AA of the scalp were collected after excluding those with alopecia totalis, universalis, AA in other body sites than scalp, those with other systemic or dermatological diseases, those received topical therapy in the last 2 weeks or systemic therapy for AA in the last three months, pregnant and lactating females. Patients were distributed into two equal groups; group A was treated by excimer lamp and group B was treated by LLLT. Sessions were repeated twice weekly for 3 months and patients were followed for 3 months. Treatment efficacy was evaluated by severity of alopecia tool score (SALT score) and Dermoscopy; at baseline, at end of sessions and at follow up.
Results: A statistically significant improvement was detected in treated patches of both groups than control patches at end of sessions and only in group A at follow up. There was no statistically significant difference between both groups according to short vellus hair and regrowing hair at end of sessions and at follow up in dermoscopy. Side effects reported were minimal and transient in both groups.
Conclusion: Both excimer light and LLLT are safe and effective in treatment of AA. Apart from its relatively higher cost, Excimer light induced better and more sustained improvement than LLLT.

Hospitalization of COVID- 19 patients may lead to the development of varied levels of anxiety, depression, and sleep disturbances. The present study was conceptualized to investigate the effect of guided meditation on anxiety, depression, and sleep quality among the hospitalized Covid-19 patients in a tertiary care facility.
Materials and Methods: A total of 60 COVID-19 patients were conveniently enrolled and randomized to experimental (30) and control arms (30) using a computer-generated random table and opaque sealed envelope technique in a selected COVID unit of a tertiary care facility. The subjects were enrolled in accordance to the inclusion criteria.
Intervention: The guided meditation was an audio recording of Sri Sri Ravi Shankar of 20 minutes duration. The intervention was provided twice a day to the experimental group for consecutive 5 days. A close watch was kept on the vital signs of the subjects during the intervention using a pulse oximeter. At the same time, the control group continued to receive the standard routine care.
Results: There was a significant difference observed in the post-test anxiety and depression scores in the experiment and control groups (4.83±3.68 vs. 12.37±3.9 p=0.001 and 7.90±2.41 vs.12.67±2.65 p=0.001). A significant difference was also observed in the global sleep quality index (median (IQR)) in the experimental and control groups (11(9-14) vs. 15(10.75-17) p= 0.01).
Conclusion: The guided meditation was effective in improving the global sleep quality index and alleviating the anxiety and depression to great extent as compared to the standard routine care provided to COVID-19 patients admitted in a tertiary care facility.

AbstractLithium dendrites caused by nonuniform Li+ flux leads to the capacity fade and short‐circuit hazard of lithium metal batteries. The solid electrolyte interface (SEI) is critical to the uniformity of Li+ flux. Here, an ultrafast preparation of uniform and vertical Cu7S4 nano‐flake arrays (Cu7S4 NFAs) on the Cu substrate is reported. These arrays can largely improve the lithiophilicity of the anode and form Li2S‐enriched SEI due to the electrochemical reduction of Cu7S4 NFAs with lithium. A further statistical analysis suggests that the SEI, with a higher content of Li2S, is more effective to inhibit the formation of lithium dendrites and yields less dead lithium. A quite stable coulombic efficiency of 98.6% can be maintained for 400 cycles at 1 mA cm–2. Furthermore, at negative to positive electrode capacity ratio of 1.5 (N/P = 1.5), the full battery of Li@Cu7S4 NFAs||S shows 83% capacity retention after 100 cycles at 1 C, much higher than that of Li@Cu||S (33%). The findings demonstrate that high Li2S content in the SEI is crucial for the dendrite inhibition to achieve better electrochemical performance.

AbstractAnion energy storage provides the possibility to achieve higher specific capacity in lithium‐ion battery cathode materials, but the problems of capacity attenuation, voltage degradation, and inconsistent redox behavior are still inevitable. In this paper, a novel O2‐type manganese‐based layered cathode material Lix[Li0.2Mn0.8]O2 with a ribbon superlattice structure is prepared by electrochemical ion exchange, which realizes the highly reversible redox of anions and excellent cycle performance. Through low‐voltage pre‐cycling treatment, the specific capacity of the material can reach 230 mAh g−1 without obvious voltage attenuation. During the electrochemical ion exchange, the precursor with P2 structure transforms into Lix[Li0.2Mn0.8]O2 with O2 structure through the slippage and shrink of adjacent slabs, and the special superlattice structure in Mn slab is still retained. Simultaneously, a certain degree of lattice mismatch and reversible distortion of the MnO6 octahedron occur. In addition, the anion redox catalyzes the formation of the solid electrolyte interface, stabilizing the electrode/electrolyte interface and inhibiting the dissolution of Mn. The mechanism of electrochemical ion exchange is systematically studied by comprehensive structural and electrochemical characterization, opening an attractive path for the realization of highly reversible anion redox.
En Route to Wide Area Emitting Organic Light‐Emitting Transistors for Intrinsic Drive‐Integrated Display Applications: A Comprehensive Review

Published: August 2021

AbstractOrganic light‐emitting transistors (OLET) evolved from the fusion of the switching functionality of field‐effect transistors (FET) with the light‐emitting characteristics of organic light‐emitting diode (OLED) that can simplify the active‐matrix pixel device architecture and hence offer a promising pathway for future flat panel and flexible display technology. This review systematically analyzes the key device/molecular engineering tactics that assist in improving the electrode edge narrow emission to wide‐area emission for display applications via three different topics, that is, narrow to wide‐area emission, vertical architecture, and impact of high‐κ dielectric on the device performance. Source–drain electrode engineering such as symmetric/asymmetric, planar/non‐planar arrangement, semitransparent nature, multilayer approach comprising charge transport, and work function modification layers enable widening the emission zone. Vertical OLET architecture offers short channel lengths with a high aperture ratio, pixel type area emission, and stable light‐emitting area. Transistors utilizing high‐κ dielectric materials have assisted in lowering the operating voltage, enhancing luminance and air stability. The promising development in achieving wide‐area emission provides a solid basis for constructing OLET research toward display applications; however, it relies on developing highly luminescent and fast charge transporting materials, suitable semitransparent source/drain electrodes, high‐κ ‐dielectrics, and device architectural engineering.

AbstractUltraflexible and ultralight rechargeable aqueous Zn‐ion batteries (ZIBs) with the merits of environmental benignity and high security arise as promising candidates for flexible electronic systems. Nowadays, the energy density and cyclical stability of ZIBs on metal‐based rigid substrates reach a satisfactory level, while the inflexible substrates severely prevent them from widespread commercial adoption in portable electronics. Although flexible substrates‐engineered devices burgeon, the development of flexible ZIBs with high specific energy still faces great challenges. Herein, a flexible ultrathin and ultralight Zn micromesh (thickness of 8 µm and areal density of 4.9 mg cm−2) with regularly aligned microholes is fabricated via combining photolithography with electrochemical machining. The unique microholes‐engineered Zn micromesh presents excellent flexibility, enhanced mechanical strength, and better wettability. Moreover, numerical simulations in COMSOL and in situ microscopic observation system certify the induced spatial‐selection deposition of Zn micromesh. Accordingly, aqueous ZIBs constructed with polyaniline‐intercalated vanadium oxide cathode and Zn micromesh anode demonstrate exceptional high‐rate capability (67.6% retention with 100 times current density expansion) and cyclical stability (maintaining 87.6% after 1000 cycles at 10.0 A g−1). Furthermore, the assembled pouch cell displays superb flexibility and durability under different scenarios, indicating great prospects in high‐energy ZIBs and flexible electronics.

Abstract2D materials with atomically precise thickness and tunable chemical composition hold promise for potential applications in nanoenergy. Herein, a bilayer‐structured VOPO4⋅2H2O (bilayer‐VOP) nanosheet is developed with high‐concentration oxygen vacancies ([Vo˙˙]) via a facile liquid‐exfoliation strategy. Galvanostatic intermittent titration technique study indicates a 6 orders of magnitude higher zinc‐ion coefficient in bilayer‐VOP nanosheets (4.6 × 10−7 cm−2 s−1) compared to the bulk counterpart. Assistant density functional theory (DFT) simulation indicates a remarkably enhanced electron conductivity with a reduced bandgap of ≈0.2 eV (bulk sample: 1.5 eV) along with an ultralow diffusion barrier of ≈0.08 eV (bulk sample: 0.13 eV) in bilayer‐VOP nanosheets, thus leading to superior diffusion kinetics and electrochemical performance. Mott–Schottky (impedance potential) measurement also demonstrates a great increase in electronic conductivity with ≈57‐fold increased carrier concentration owing to its high concentration [Vo˙˙]. Benefited by these unique features, the rechargeable zinc‐ion battery composed of bilayer‐VOP nanosheets cathode exhibits a remarkable capacity of 313.6 mAh g−1 (0.1 A g−1), an energy density of 301.4 Wh kg−1, and a prominent rate capability (168.7 mAh g−1 at 10 A g−1).

AbstractThe application of superconcentrated aqueous electrolytes has shown great potential in developing high‐voltage electrochemical double‐layer capacitors (EDLCs). However, the broadening of the electrochemical window of such superconcentrated electrolytes is at the expense of their high cost, low ionic conductivity, high density, and narrow operating temperature range. Herein, the electrochemical window of water (>3 V) at low salt concentration (3 m) is expanded by using an aprotic solvent, i.e., trimethyl phosphate (TMP), to regulate the solvation structure of the electrolyte. Benefiting from the low salt concentration, such electrolyte is simultaneously featured with high ionic conductivity, low density, and wide temperature compatibility. Based on the dilute hybrid electrolyte, EDLCs constructed by using porous graphene electrodes are able to operate within an enlarged voltage range of 0–2.4 V at a wide range of temperatures from −20 to 60 °C. They also present excellent rate capability and cycle stability, i.e., 83% capacitance retention after 100 000 cycles. Density functional theory calculations verify that TMP induces a significant electronic modulation for the bonding environment of the electrolyte. This enables the stronger binding of Na+–H2O with freely migrating TMP to expand the voltage window to exceed the potential limitation of aqueous electrolytes.

AbstractMalus’ law regulating the intensity of light when passed through a polarizer, forms the solid basis for image steganography based on orthogonal polarizations of light to convey hidden information without adverse perceptions, which underpins important practices in information encryptions, anti‐counterfeitings, and security labels. Unfortunately, the restriction to orthogonal states being taken for granted in the common perceptions fails to advance cryptoinformation to upgraded levels of security. By introducing a vectorial compound metapixel design, arbitrary nonorthogonal polarization multiplexing of independent grayscale images with high fidelity and strong concealment is demonstrated. The Jones matrix treatment of compound metapixels consisting of double atoms with tailored in‐plane orientation sum and difference allows point‐by‐point configuring of both the amplitude and polarization rotations of the output beam in an analytical and linear form. With this, both multiplexing two continuous grayscale images in arbitrary nonorthogonal polarization angles and concealing grayscale image on another in an arbitrary disclosure angle window are experimentally demonstrated in the visible TiO2 metasurface platform. The methods shed new light on multifarious metaoptics by harnessing the new degree of freedom and unlock the full potential of metasurface polarization optics.
