Half Metallic Ferromagnetism and Transport Properties of Zinc Chalcogenides ZnXSe (X = Ti, V, Cr) for Spintronic Applications.

In ferromagnetic semiconductors, the coupling of magnetic ordering with semiconductor character accelerates the quantum computing. The structural stability, Curie temperature (T), spin polarization, half magnetic ferromagnetism and transport properties of ZnXSe (X = Ti, V, Cr) chalcogenides for spintronic and thermoelectric applications are studied here by density functional theory (DFT). The highest value of T is perceived for ZnCrSe.

Role of nebulized epinephrine in moderate bronchiolitis: a quasi-randomized trial.

Background/aims: Bronchiolitis is the most common lower respiratory illness that characteristically affects the children below 2 years of age accounting about 2-3% of patients admitted to hospital each year [1-4]. We compared the effect of racemic epinephrine (RE) and 3% hypertonic saline (HS) nebulization on the length of stay (LOS) in the hospital.

Methods: We looked at the infants with moderate bronchiolitis, from October 2013 to March 2014.

Investigating the subjective cooling effect of eyelid cleansing gel on eyelid and ocular surface temperature.

Purpose: To investigate if the application of Blephagel, an eyelid cleansing gel, causes subjective and/or objective cooling effects by measuring ocular symptomology and temperature.

Methods: Twenty-five healthy subjects underwent baseline non-invasive temperature measurements on the closed upper eyelid (centrally, nasally, and temporally) and ocular surface temperature (OST) on both eyes using an infrared camera. A standard application of Blephagel was then applied to the closed upper eyelid and eyelashes with a sterile cotton-wool to one eye selected at random.

First principle study of electronic, mechanical, optical and thermoelectric properties of CsMO (M = Ta, Nb) compounds for optoelectronic devices.

The electronic, mechanical, optical and thermoelectric properties of Cesium based perovskites CsMO (M = Nb, Ta) in the cubic phase has been performed through PBEsol-mBJ scheme in the framework of DFT. The electronic band structures and density of states show the studied materials having a direct band gap in the visible range. The mechanical stability and ductile behavior have been analyzed from elastic constants.

Unveiling surface redox charge storage of interacting two-dimensional heteronanosheets in hierarchical architectures.

Two-dimensional (2D) heteronanosheets are currently the focus of intense study due to the unique properties that emerge from the interplay between two low-dimensional nanomaterials with different properties. However, the properties and new phenomena based on the two 2D heteronanosheets interacting in a 3D hierarchical architecture have yet to be explored. Here, we unveil the surface redox charge storage mechanism of surface-exposed WS2 nanosheets assembled in a 3D hierarchical heterostructure using in situ synchrotron X-ray absorption and Raman spectroscopic methods.

Anomalous nanoinclusion effects of 2D MoS2 and WS2 nanosheets on the mechanical stiffness of polymer nanocomposites.

Polymer inorganic nanosheet composites hold great promise in enhancing their physical and mechanical properties by increasing the interfacial area. Herein, we demonstrate the nanoinclusion effects of two-dimensional (2D) molybdenum disulfide (MoS2) and tungsten disulfide (WS2) nanosheets on the mechanical properties of the poly(vinyl alcohol) (PVA) polymer. At very small amounts of nanosheets (0.

Surface functional groups of carbon nanotubes to manipulate capacitive behaviors.

The covalent functionalization of carbon nanotubes (CNTs) is a basic but important chemistry that can modify their physicochemical properties, resolve their poor dispersion capability, and improve their capacitance to enable their use as high-energy supercapacitors. However, the relationship between functional groups on the CNT surface and their capacitive characteristics has not yet been explored. Here, we demonstrate the influence of carboxylic, sulfonic, and amine groups tethered to CNTs (Cf-CNTs, Sf-CNTs, and Nf-CNTs, respectively) on capacitor performance in an organic electrolyte.

Seamless reconstruction of intact adult-born neurons by serial end-block imaging reveals complex axonal guidance and development in the adult hippocampus.

In the adult mammalian hippocampus, newborn dentate granule cells are continuously integrated into the existing circuitry and contribute to specific brain functions. Little is known about the axonal development of these newborn neurons in the adult brain due to technological challenges that have prohibited large-scale reconstruction of long, thin, and complex axonal processes within the mature nervous system. Here, using a new serial end-block imaging (SEBI) technique, we seamlessly reconstructed axonal and dendritic processes of intact individual retrovirus-labeled newborn granule cells at different developmental stages in the young adult mouse hippocampus.

Structure and compositional control of MoO3 hybrids assembled by nanoribbons for improved pseudocapacitor rate and cycle performance.

Hierarchical structures of transition metal oxides with well-defined compositions are crucial for achieving advanced electrodes for energy storage devices. Herein, we first demonstrate the hierarchically structured MoO(3) assembled by twisted nanoribbons with a hybrid composition for improved rate capability and cycle stability of the pseudocapacitor. The hierarchical, flower-like structures of MoO(3) assembled by hybrid nanoribbons were induced by the specific interactions of MoO(3) interlayers with ionic liquids (ILs), as proven by spectroscopic and electrochemical analyses.

Compliance of child care centers in Pennsylvania with national health and safety performance standards for emergency and disaster preparedness.

Objectives: To determine the preparedness of child care centers in Pennsylvania to respond to emergencies and disasters based on compliance with National Health and Safety Performance Standards for Out-of-Home Child Care Programs.

Methods: A questionnaire focusing on the presence of a written evacuation plan, the presence of a written plan for urgent medical care, the immediate availability of equipment and supplies, and the training of staff in first aid/cardiopulmonary resuscitation (CPR) as delineated in Caring for Our Children: National Health and Safety Performance Standards for Out-of-Home Child Care Programs, 2nd Edition, was mailed to 1000 randomly selected child care center administrators located in Pennsylvania.

Results: Of the 1000 questionnaires sent, 496 questionnaires were available for analysis (54% usable response rate).

Iatrogenic superior vena caval syndrome.

The superior vena caval (SVC) syndrome is a common oncological emergency requiring the quick initiation of appropriate therapy. However, it may also result from a medical procedure e.g.
