Abstract

Objective: Acute myocardial infarction (AMI) is one of the leading causes of death; however, updated data regarding clinical presentation and current management are missing in Greece. This study aimed to prospectively record the demographic and clinical characteristics of a representative sample of patients suffering from AMI, their management, and short-term outcomes. Methods: ILIAKTIS is a national, prospective, multicenter, noninterventional study conducted under the auspices of Hellenic Society of Cardiology (HCS) and the European Initiative Stent - Save a Life. From 1st April 2020 to 30th June 2020, consecutive adult patients with STEMI or NSTEMI were enrolled in the 50 participating hospitals, appropriately selected to match the geographical and population distribution in the Greek territory. Results: In total, 1862 patients (mean age: 64.2 ± 13.2 yrs.; 77.2% males) with AMI were enrolled. More patients presented with NSTEMI (56.8%) than with STEMI (43.2%). Primary PCI (pPCI) was the preferable treatment option for STEMI patients in PCI-hospitals (76.9% vs. 39.9% for non-PCI, p

Abstract

Composite materials of the type polyaniline (PANI)-polyoxometalates (POM = XM12, X = P, Si and M = Mo, W) were synthesized and characterized by means of FT-IR, UV-vis, SEM, XRD, SAXS analysis and cyclic voltammetry. Suspensions of 2.5 mg mL�1 PANI-PMo12 in 2% (w/v) poly(ethyleneimine) (PEI) in methanol were prepared and deposited onto graphene oxide-modified graphite electrodes. These were tested as sensors for the ability to electrocatalyze the reduction of bromates by using cyclic voltammetry. Various experimental variables such as the loading of the composite material, the concentration of PEI, the pH and the composition of electrolyte, and the electrode material were optimized. By performing DC amperometry at a fixed potential of �0.3 V, versus a Ag/AgCl reference electrode, in 0.05 M HCl, a linear calibration curve over the concentration range 7.5 × 10�6 to 5.0 × 10�4 M BrO3� was constructed. The 3σ limit of detection and the relative standard deviation of the method were 3.0 × 10�6 M BrO3� and 3% (n = 7, 1 × 10�4 M BrO3�), respectively. The accuracy of the method was established by recovery studies in spiked drinking water and flour extract samples. Recovery was 95.4-100.2%. Finally, the sensors exhibited a remarkable working and storage stability when they kept dry in ambient conditions. Sensors and Actuators B: Chemical

Abstract

Several types of source-receptor modeling methods have been applied to the atmospheric mercury data collected by the long term monitoring site at PMRC, Underhill, VT to infer the possible emission source types and source areas that may have significant contributions to mercury deposition into the Lake Champlain Basin. The methods employed were potential source contribution function (PSCF) analysis, residence time analysis (RTA), and multiple regression analysis against the factors of the positive matrix factorization (PMF) of the fine particulate data from the same site. The possible source areas are displayed by the PSCF maps and the RTA maps. Source contributions were calculated for vapor phase and particulate mercury.

5. Controlling Solar Hydrogen Production by Organizing Porphyrins.

Abstract

In this study, a highly efficient photocatalytic H 2 production system is developed by employing porphyrins as photocatalysts. Palladium and platinum tetracarboxyporphyrins (PdTCP and PtTCP) are adsorbed or coadsorbed onto TiO 2 nanoparticles (NPs), which act as the electron transport medium and as a scaffold that promotes the self-organization of the porphyrinoids. The self-organization of PdTCP and PtTCP, forming H- and J-aggregates, respectively, is the key element for H 2 evolution, as in the absence of TiO 2 NPs no catalytic activity is detected. Notably, J-aggregated PtTCPs are more efficient for H 2 production than H-aggregated PdTCPs. In this approach, a single porphyrin, which self-organizes onto TiO 2 NPs, acts as the light harvester and simultaneously as the catalyst, whereas TiO 2 serves as the electron transport medium. Importantly, the concurrent adsorption of PdTCP and PtTCP onto TiO 2 NPs results in the most efficient catalytic system, giving a turnover number of 22,733 and 30.2 mmol(H 2 ) g(cat) -1 ., (© 2020 Wiley-VCH GmbH.)

6. A Hybrid {Silk@Zirconium MOF} Material as Highly Efficient As III -sponge.

Author

Abstract

Exposure of humans to Arsenic from groundwater drinking sources is an acute global public health problem, entailing the urgent need for highly efficient/low-cost Arsenite (As III ) up-taking materials. Herein we present an innovative hybrid-material, ZrMOF@SF d operating like an "As III -sponge" with unprecedented efficiency of 1800 mg As III gr -1 . ZrMOF@SF d consists of a neutral Zirconium Metal-Organic Framework [ZrMOF] covalently grafted on a natural silk-fiber (SF d ). ZrMOF itself exhibits As III adsorption of 2200 mg gr -1 , which supersedes any -so far- known As ΙΙΙ -sorbent. Using XPS, FTIR, BET-porosimetry data, together with theoretical Surface-Complexation-Modeling (SCM), we show that the high-As ΙΙΙ -uptake is due to a sequence of two phenomena:[i] at low As III -concentrations, surface-complexation of H 3 AsO 3 results in As III -coated voids of ZrMOF, [ii] at increased As III -concentrations, the As III -coated voids of ZrMOF are filled-up by H 3 AsO 3 via a partitioning-like mechanism. In a more general context, the present research exemplifies a mind-changing concept, i.e. that a "partitioning-like" mechanism can be operating for adsorption of metalloids, such as H 3 AsO 3, by metal oxide materials. So far, such a mechanism has been conceptualized only for the uptake of non-polar organics by natural organic matter or synthetic polymers.

7. Activation of tellurium with Zintl ions: 1/infinity{[Ge5Te10]4-}, an inorganic polymer with germanium in three different oxidation states.

Author

Zhang Q, Armatas G, and Kanatzidis MG

Abstract

The solvothermal reaction among tellurium, manganese, and the Zintl compound K(4)Ge(9) has led to the formation of a polymeric mixed-valent complex {[Mn(en)(3)](2)(Ge(5)Te(10))}(n) (1; en = ethylenediamine). The most interesting structural feature of this material is the presence of three different oxidation states of germanium centers and the formation of Ge-Ge bonds in the infinite polymeric chains (1)/(infinity){[Ge(5)Te(10)](4-)}. X-ray photoelectron spectroscopy characterization confirms the different oxidation states of germanium.

8. Pore anisotropy and microporosity in nanostructured mesoporous solids.

Author

Knowles J, Armatas G, Hudson M, and Pomonis P

Abstract

In this study, we carried out an investigation related to the determination of the anisotropy (b) of pores as well as the extent of microporosity (mic%) in various groups of nanostructured mesoporous materials. The mesoporous materials examined were fifteen samples belonging to the following groups of solids: MCM-48s, SBA-15s, SBA-16s, and mesoporous TiO(2) anatases. The porosities of those materials were modified either during preparation or afterward by the addition of Cu(II) species and/or 3(5)-(2-pyridinyl) pyrazole (PyPzH) into the pores. The modification of porosity in each group took place to make possible the internal comparison of the b and mic% values within each group. The estimation of both the b and mic% parameters took place from the corresponding nitrogen adsorption-desorption isotherms. The new proposed method is able to detect a percentage of microporosity as low as a few percent, which is impossible by any of the methods used currently, without the use of any reference sample or standard isotherms. A meaningful inverse relationship is apparent between the b and mic% values, indicating that large values of b correspond to small values of mic%.
