Phosphide delivery to a cyclotrisilene.

ABSTRACT: The reactivity of the 2-phosphaethynolate anion (PCO(-)) towards a cyclic trisilene (cSi3(Tip)4) is reported. The result is the net activation of the P-C and Si-Si multiple bonds of the precursors affording a heteroatomic bicyclo[1.1.1]pentan-2-one analogue ([P(CO)Si3(Tip)4](-); 1). This reaction can be interpreted as the formal addition of a phosphide and a carbonyl across the Si-Si double bond. Photolytic decarbonylation of 1 results in the incorporation of the phosphide vertex into the cyclotrisilene scaffold, yielding a congener of the cyclobutene anion with considerable allylic character.

Enhanced hydrogen evolution reaction on hybrids of cobalt phosphide and molybdenum phosphide.

Project description:Production of hydrogen from water electrolysis has stimulated the search of sustainable electrocatalysts as possible alternatives. Recently, cobalt phosphide (CoP) and molybdenum phosphide (MoP) received great attention owing to their superior catalytic activity and stability towards the hydrogen evolution reaction (HER) which rivals platinum catalysts. In this study, we synthesize and study a series of catalysts based on hybrids of CoP and MoP with different Co/Mo ratio. The HER activity shows a volcano shape and reaches a maximum for Co/Mo = 1. Tafel analysis indicates a change in the dominating step of Volmer-Hyrovský mechanism. Interestingly, X-ray diffraction patterns confirmed a major ternary interstitial hexagonal CoMoP2 crystal phase is formed which enhances the electrochemical activity.

The ?-polymorph of uranium phosphide selenide.

Project description:?-UPSe was synthesized from the reaction of U(2)Se(3), P and Se in a CsCl flux in a fused-silica tube. It crystallizes with four formula units in the tetra-gonal space group I4/mmm in the UGeTe structure type. The asymmetric unit comprises one U (site symmetry 4mm), one Se (4mm), and one P (mmm.) atom. The U atom is coordinated in a monocapped square-anti-prismatic arrangement, where the square face is formed by P atoms and the other five vertices are Se atoms. The P site is disordered about a mirror plane, showing half-ocupancy for each of the two resulting P atoms. The title structure is related to that of ?-UPSe, which crystallizes with two formula units in the tetra-gonal space group P4/nmm in the PbFCl structure type.

PROGNOSTIC FACTORS IN ALUMINIUM PHOSPHIDE POISONING.

Project description:A prospective study was done on 12 consecutive cases of aluminium phosphide poisoning admitted to a zonal hospital in Punjab. Patients were in 18-36 years age group and mortality was more in females. The dose of aluminium phosphide was more in non-survivors and fresh tablets were more likely to cause fatality. Early vomitting and prompt initiation of treatment resulted in better outcome. Survivors responded to treatment early, but duration of shock had no predictive value. Shock and cardiac arrhythmias were present in all cases and extracardiac complications occurred more commonly in fatal group. With vigorous treatment of shock and other complications 33 per cent of the cases could be saved.

Efficient water reduction with gallium phosphide nanowires.

Project description:Photoelectrochemical hydrogen production from solar energy and water offers a clean and sustainable fuel option for the future. Planar III/V material systems have shown the highest efficiencies, but are expensive. By moving to the nanowire regime the demand on material quantity is reduced, and new materials can be uncovered, such as wurtzite gallium phosphide, featuring a direct bandgap. This is one of the few materials combining large solar light absorption and (close to) ideal band-edge positions for full water splitting. Here we report the photoelectrochemical reduction of water, on a p-type wurtzite gallium phosphide nanowire photocathode. By modifying geometry to reduce electrical resistance and enhance optical absorption, and modifying the surface with a multistep platinum deposition, high current densities and open circuit potentials were achieved. Our results demonstrate the capabilities of this material, even when used in such low quantities, as in nanowires.

Direct band gap wurtzite gallium phosphide nanowires.

Project description:The main challenge for light-emitting diodes is to increase the efficiency in the green part of the spectrum. Gallium phosphide (GaP) with the normal cubic crystal structure has an indirect band gap, which severely limits the green emission efficiency. Band structure calculations have predicted a direct band gap for wurtzite GaP. Here, we report the fabrication of GaP nanowires with pure hexagonal crystal structure and demonstrate the direct nature of the band gap. We observe strong photoluminescence at a wavelength of 594 nm with short lifetime, typical for a direct band gap. Furthermore, by incorporation of aluminum or arsenic in the GaP nanowires, the emitted wavelength is tuned across an important range of the visible light spectrum (555-690 nm). This approach of crystal structure engineering enables new pathways to tailor materials properties enhancing the functionality.

Optical Properties of Strained Wurtzite Gallium Phosphide Nanowires.

Project description:Wurtzite gallium phosphide (WZ GaP) has been predicted to exhibit a direct bandgap in the green spectral range. Optical transitions, however, are only weakly allowed by the symmetry of the bands. While efficient luminescence has been experimentally shown, the nature of the transitions is not yet clear. Here we apply tensile strain up to 6% and investigate the evolution of the photoluminescence (PL) spectrum of WZ GaP nanowires (NWs). The pressure and polarization dependence of the emission together with a theoretical analysis of strain effects is employed to establish the nature and symmetry of the transitions. We identify the emission lines to be related to localized states with significant admixture of ?7c symmetry and not exclusively related to the ?8c conduction band minimum (CBM). The results emphasize the importance of strongly bound state-related emission in the pseudodirect semiconductor WZ GaP and contribute significantly to the understanding of the optoelectronic properties of this novel material.

Gallium phosphide optical metasurfaces for visible light applications.

Project description:There are few materials that are broadly used for fabricating optical metasurfaces for visible light applications. Gallium phosphide (GaP) is a material that, due to its optical properties, has the potential to become a primary choice but due to the difficulties in fabrication, GaP thin films deposited on transparent substrates have never been exploited. In this article we report the design, fabrication, and characterization of three different amorphous GaP metasurfaces obtained through sputtering. Although the material properties can be further optimized, our results show the potential of this material for visible applications making it a viable alternative in the material selection for optical metasurfaces.

Structural Diversity in Molecular Nickel Phosphide Carbonyl Nanoclusters.

Project description:The reaction of [Ni6(CO)12]2- as a [NBu4]+ salt in CH2Cl2 with 0.8 equiv of PCl3 afforded [Ni14P2(CO)22]2-. In contrast, the reactions of [Ni6(CO)12]2- as a [NEt4]+ salt with 0.4-0.5 equiv of POCl3 afforded [Ni22-xP2(CO)29-x]4- (x = 0.84) or [Ni39P3(CO)44]6- by using CH3CN and thf as a solvent, respectively. Moreover, by using 0.7-0.9 mol of POCl3 per mole of [NEt4]2[Ni6(CO)12] both in CH3CN and thf, [Ni23-xP2(CO)30-x]4- (x = 0.82) was obtained together with [Ni22P6(CO)30]2- as a side product. [Ni23-xP2(CO)30-x]4- (x = 0.82) and [Ni22P6(CO)30]2- were separated owing to their different solubility in organic solvents. All the new molecular nickel phosphide carbonyl nanoclusters were structurally characterized through single crystal X-ray diffraction (SC-XRD) as [NBu4]2[Ni14P2(CO)22] (two different polymorphs, P21/n and C2/c), [NEt4]4[Ni23-xP2(CO)30-x]·CH3COCH3·solv (x = 0.82), [NEt4]2[Ni22P6(CO)30]·2thf, [NEt4]4[Ni22-xP2(CO)29-x]·2CH3COCH3( x = 0.84) and [NEt4]6[Ni39P3(CO)44]·C6H14·solv. The metal cores' sizes of these clusters range from 0.59 to 1.10 nm, and their overall dimensions including the CO ligands are 1.16-1.63 nm. In this respect, they are comparable to ultrasmall metal nanoparticles, molecular nanoclusters, or atomically precise metal nanoparticles. The environment of the P atoms within these molecular Ni-P-CO nanoclusters displays a rich diversity, that is, Ni5P pentagonal pyramid, Ni7P monocapped trigonal prism, Ni8P bicapped trigonal prism, Ni9P monocapped square antiprism, Ni10P sphenocorona, Ni10P bicapped square antiprism, and Ni12P icosahedron.

Successfully managed aluminum phosphide poisoning: A case report.

Project description:Introductionand Importance: Aluminum phosphide (ALP) is a commonly available pesticide in agricultural countries like Nepal. Upon ingestion, this releases highly toxic phosphine gas in the gastrointestinal tract when it comes in contact with humidity. This leads to refractory shock, metabolic acidosis, cardiac arrhythmia, renal failure, and hepato-biliary impairment.Case presentationWe present a successfully managed case of a 17-year-old girl who ingested 6 g (2 tablets) of ALP tablets with suicidal intent. Although the mortality has been reported as 70-100% with mere ingestion of 150-500 mg of ALP, this case survived even after developing severe metabolic acidosis, acute renal failure, refractory shock, and ventricular tachycardia.Clinical discussionALP poisoning is most often lethal. However, there is an emerging evidence of successful use of various drugs such as magnesium sulfate, trimetazidine, and other interventions such as intra-aortic balloon pump and extra corporeal membrane oxygenation in case of ALP poisoning.ConclusionOwing to the unavailability of an effective antidote of ALP to date, we emphasize early initiation of supportive management, intensive monitoring, and potential role of membrane stabilizers like magnesium sulfate, and cardio-protective agents like trimetazidine, N-Acetyl cysteine, thiamine, vitamin C, and hydrocortisone in decreasing the likelihood of fatal outcome.

Thermoelectric transports in pristine and functionalized boron phosphide monolayers.

Project description:Recently, a new monolayer Group III-V material, two-dimensional boron phosphide (BP), has shown great potential for energy storage and energy conversion applications. We study the thermoelectric properties of BP monolayer as well as the effect of functionalization by first-principles calculation and Boltzmann transport theory. Combined with a moderate bandgap of 0.90 eV and ultra-high carrier mobility, a large ZT value of 0.255 at 300 K is predicted for two-dimensional BP. While the drastically reduced thermal conductivity in hydrogenated and fluorinated BP is favored for thermoelectric conversion, the decreased carrier mobility has limited the improvement of thermoelectric figure of merit.
