Intense psychosis as well as serotonin syndrome inside the placing of "Triple-C" overdose: an incident record.
In this work, the structural, electrical, and optical properties of bilayer SiX (X= N, P, As, and Sb) are studied using density functional theory. Five different stacking orders are considered for every compound and their structural properties are presented. The band structure of these materials demonstrates that they are indirect semiconductors. The out-of-plane strain has been applied to tune the bandgap and its electrical properties. The bandgap increases with tensile strain, whereas, compressive strain leads to semiconductor-to-metal transition. SU056 RNA Synthesis inhibitor The sensitivity of the bandgap to the pressure is investigated and bilayer SiSb demonstrates the highest bandgap sensitivity to the pressure. These structures exhibit Mexican hat-like valence band dispersion that can be approved by a singularity in the density of states (DOS). The Mexican-hat coefficient can be tuned by out-of-plane strain. Optical absorption of these compounds shows that the second and lower valence bands due to the high DOS display a higher contribution to optical transitions.Binary transition metal oxides with encouraging electrocatalyst properties have been suggested as electrode materials for supercapacitors and methanol oxidation. Hence, in this work, a binary mixed metal oxide based on nickel and manganese (MnNi2O4) and its hybrid with reduced graphene oxide were synthesized by a one-step hydrothermal method. After physical and morphological characterization, the potential of these nanostructures was investigated for use as supercapacitor electrodes and methanol electro-oxidation. The results of the electrochemical analysis showed a substantial effect of adding rGO to the MnNi2O4. The MnNi2O4/rGO hybrid electrode supercapacitor exhibited good stability of 93% after 2000 consecutive CV cycles and a specific capacitance of 575 F g-1at the current density of 0.5 A g-1. Furthermore, the application of this hybrid nanomaterial in the methanol electro-oxidation reaction (MOR) indicated its appropriate electrochemical efficiency and stability in methanol oxidation. Our results show that MnNi2O4/rGO can be considered as a promising electrode material for energy applications.In a combined experimental and theoretical study, we investigated how Fe and Co adlayers on W(110) affect the Dirac-type surface state (DSS). Angle-resolved photoelectron spectroscopy data show an increase in binding energy of 75 meV and 107 meV for Fe and Co, respectively. In order to identify the origin of the energy shift we performed first-principles calculations of the surface electronic structure. The inward surface relaxation of the uncovered W(110) surface is lifted by the adlayers. This structural change is one reason of the energy shift of the DSS. Furthermore, the Fe and Co adlayers change the surface potential, which results in an additional energy shift of the DSS.The exciton properties of (Cd,Mn)Se-NrGO (nitrogen doped reduced graphene oxide) hybrid layered nanosheets have been studied in a magnetic field up to 10 T and compared to those of (Cd,Mn)Se nanosheets. The temperature dependent photoluminescence reveals the hybridization of inter-band exciton and intra-center Mn transition with enhancement of the binding energy of exciton-Mn hybridized state (80 meV with respect to 60 meV in (Cd,Mn)Se nanosheets) and increase of exciton-phonon coupling strength to 90 meV (with respect to 55 meV in (Cd,Mn)Se nanosheets). The circularly polarized magneto-photoluminescence at 2 K provides evidence for magnetic field induced exciton spin polarization and the realization of excitonic giant Zeeman splitting withgeffas high as 165.4 ± 10.3, much larger than in the case of (Cd,Mn)Se nanosheets (63.9 ± 6.6), promising for implementation in spin active semiconductor devices.Biomaterials constructed exclusively of sintered microspheres have great potential in tissue engineering scaffold applications, offering the ability to create shape-specific scaffolds with precise controlled release yet to be matched by traditional additive manufacturing methods. The problem is that these microsphere-based scaffolds are limited in their stiffness for applications such as bone regeneration. Our vision to solve this problem was borne from a hierarchical structure perspective, focusing on the individual unit of the structure the microsphere itself. In a core-shell approach, we envisioned a stiff core to create a stiff microsphere unit, with a polymeric shell that would enable sintering to the other microsphere units. Therefore, the current study provided a comparison of macroscopic biomaterials built on either polymer microspheres or polymer-coated hard glass microspheres. Identical polycaprolactone (PCL) polymer solutions were used to fabricate microspheres and as a thin coating on soda lime glass microspheres (hard phase). The materials were characterized as loose particles and as scaffolds via scanning electron microscopy, thermogravimetry, differential scanning calorimetry, Raman spectroscopy, mechanical testing, and a live/dead analysis with human umbilical cord-derived Wharton's jelly cells. The elastic modulus of the scaffolds with the thinly coated hard phase was about five times higher with glass microspheres (up to about 25 MPa) than pure polymer microspheres, while retaining the structure, cell adhesion, and chemical properties of the PCL polymer. This proof-of-concept study demonstrated the ability to achieve at least a five-fold increase in macroscopic stiffness via altering the core microsphere units with a core-shell approach.The world is facing alarming challenges of environmental pollution due to uncontrolled water contamination and multiple drug resistance of pathogens. In this work, SnO2nanorods and SnO2/GNPs nanocomposites have been prepared. The length and diameter of nanorods are ca. 25±6 nm and 4±2 nm respectively. The optical bandgap energies change from 3.14 eV to 2.80 eV in SnO2and SnO2/GNPs nanocomposite (GS-I and GS-II). SnO2nanorods and multifunctional SnO2/GNPs nanocomposites have been tested as photocatalysts and nano-antibiotics. SnO2/GNPs nanocomposite (GS-II) completely removes (99.11%) malachite green in 12 min, under UV light exposure, which has been removed only 37% by neat SnO2nanorods in the same time. In visible light, GS-II removes 99.01% malachite green in 15 min, while SnO2removes the same only upto 24.7% in the same time. In addition, GS-II nanocomposite inhibits 79.57% and 78.51% growth of P. aeruginosa and S. aureus respectively. A synchronized contribution of SnO2and GNPs makes SnO2/GNPs nanocomposites (GS-II) an innovative multifunctional material for simultaneous fast and complete removal of malachite green and inhibition of drug resistant pathogens.
