Nuclear power is becoming one of the major clean energies for its high efficiency and low load on the environment. Uranium is a key strategic resource for nuclear power. Uranium reclamation from aqueous systems is of great significance, not only in the usage of nuclear power but also for the remediation of nuclear leakage pollution. Recently, metal-organic frameworks (MOFs) with high porosity, regular pore structure and modifiable functional groups, have been considered as one of the most effective uranium adsorption materials. Specifically, the post-grafted functional groups possess strong affinity to uranium. This frontier summarizes the recent progresses on grafting functional groups in MOFs for U(vi) sorption from aqueous solutions. The adsorption performance, interaction mechanisms and the grafted functional groups are assessed in this study. Finally, personal perspectives on challenges and opportunities are discussed with the hope of supporting and providing some assistance to the designation of MOF-based U(vi) sorption materials.A two-dimensional (2D) layered material-based p-n diode is an essential element in the modern semiconductor industry for facilitating the miniaturization and structural flexibility of devices with high efficiency for future optoelectronic and electronic applications. Planar devices constructed previously required a complicated device structure using a photoresist, as they needed to consider non-abrupt interfaces. click here Here, we demonstrated a WSe2 based lateral homojunction diode obtained by applying a photo-induced effect in BN/WSe2 heterostructures upon illumination via visible and deep UV light, which represents a stable and flexible charge doping technique. We have discovered that with this technique, a field-effect transistor (FET) based on p-type WSe2 is inverted to n-WSe2 so that a high electron mobility is maintained in the h-BN/n-WSe2 heterostructures. To confirm this hypothesis, we deduced the work function values of p-WSe2 and n-WSe2 FETs by conducting Kelvin probe force microscopy (KPFM) measurements, which revealed the decline of the Fermi level from 5.07 (p-WSe2) to 4.21 eV (n-WSe2). The contact potential difference (CPD) between doped and undoped junctions was found to be 165 meV. We employed ohmic metal contacts for the planar homojunction diode by utilizing an ionic liquid gate to achieve a diode rectification ratio up to ∼105 with n = 1. An exceptional photovoltaic performance is also observed. The presence of a built-in potential in our devices leads to an open-circuit voltage (Voc) and short-circuit current (Isc) without an external electric field. This effective doping technique is promising to advance the concept of preparing future functional devices.Urban expansion can worsen climate change conditions and enlarge hazard zones. Sea level rise due to climate change makes coastal populations more susceptible to flood risks. The use of land change prediction modelling to inform scenario-based planning has been shown to help increase capabilities when dealing with uncertainties in urbanization such as urban growth and flood risk, when compared to singular comprehensive plans. This research uses the Land Transformation model to predict three different urban growth scenarios for Tampa, FL to determine how effective the current comprehensive plan is in adapting urban growth to decreasing flood risk and pollutant load. To achieve this, the research develops master plans according to each scenario then assesses their probable impact using the Long-Term Hydrologic Impact Analysis Low Impact Development Spreadsheet as a performance model. Findings show that the current future land use plan for Tampa, while it appears to be better than current patterns of development, has higher flood exposure, stormwater runoff, and pollutant discharge that current conditions but more than a purely resilient approach to future growth.Background Most end-of-life decisions after stroke are made by a surrogate decision maker, yet there has been limited study of surrogate assessment of the quality of end-of-life stroke care. Objective To assess surrogate perceptions of quality of end-of-life care (QEOLC) in stroke and explore factors associated with quality. Design Cross-sectional analysis of interviewer-administered survey. Settings/subjects Surrogate decision makers for deceased stroke patients in a population-based study. Measurements The primary outcome was the validated 10-item family version of the QEOLC scale. The univariate association between prespecified patient and surrogate factors and dichotomized QEOLC score (high 8-10, low 0-7) was explored with logistic regression fit using generalized estimating equations. Results Seventy-nine surrogates for 66 deceased stroke cases were enrolled (median patient age 76, female patient 53%, Mexican American patient 59%, median time from stroke to death seven days, median surrogate age 59, and female surrogate 72%). The overall QEOLC was generally high (median 8.3, quartiles 6.1, 9.6) although several individual items had a high proportion (∼30%-50%) of surrogates who felt that the questions did not apply to the patient's situation. No hypothesized factors were associated with QEOLC score, including demographics, stroke type, location/timing of death, advance directives, health literacy, or understanding of patient wishes. Conclusions Surrogates reported generally high QEOLC. Although this finding is encouraging, modifications to the QEOLC may be needed in stroke as some surrogates were unable to provide a valid response for certain items.Background New Orleans, Louisiana served as a central location for a surge of novel coronavirus cases during the months of March 2020 to May 2020. To provide guidance to palliative care teams naive to the palliative care demand associated with a surge of coronavirus cases, we document our protocol to best optimize palliative care resources. This report aims to present this information and reflect upon what was most beneficial/least beneficial to serve as a roadmap for palliative teams facing this pandemic. Objective To pilot a team-based structured protocol to categorize severity of COVID-19 intensive care unit (ICU) admissions and subsequently collaborate with the palliative interdisciplinary team to assess physical, spiritual, and psychosocial needs. Design New ICU consults were categorized into color-coded clinical severity "pots" during daily ICU interdisciplinary rounds. Clinical decision making and communication with patient/next of kin were based on "pot" classification. Settings/Subjects Palliative medicine consults were placed on all COVID-19 positive patients admitted to the ICU between March 29, 2020, and May 1, 2020.
