A total of 26 samples of surface sediments collected in the Neva River (including the St. Petersburg city area) and in the Russian part of the Gulf of Finland were analyzed for 17 polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans (PCDD/Fs), 12 dioxin-like polychlorinated biphenyls (dl-PCBs), and 10 polybrominated diphenyl ethers (PBDEs). The concentrations of total PCDD/Fs and dl-PCBs in sediments ranged from <0.05 to 219pgg(-1)d.w. and from 44 to 246,600pgg(-1)d.w. respectively. The total World Health Organization toxic equivalent (WHO-TEQ(PCDD/F + PCB)) values varied between 0.01 and 59.0pgg(-1). In the majority of cases, the PCDD/F and dl-PCB concentrations do not exceed the threshold effect level (TEL) recommended by Helsinki Commission (HELCOM) as quantitative target for the sum of PCDD/Fs and dl-PCBs. The congener profile indicates that combustion is the primary source of PCDD/Fs in most of the studied samples. For the PCBs, the historical use of technical PCB products was identified as the major source. sigma PBDE10 concentrations ranged from 0.004 to 1.8ngg(-1)d.w. The congener profile results show that BDE-47 (tetra-BDE) is the dominant congener in sediment samples. According to the sediment and water quality guidelines established in the EU (PNEC) and in Canada (FEQG), all the samples studied can be classified as lowly contaminated by PBDEs. The sediment concentrations of PCDD/Fs, dl-PCBs, and PBDEs measured in this study were comparable to or lower than those reported for other areas of the Baltic Sea. Formula: C12H10O.

Advanced chemometric methods, such as fuzzy c-means, a semi-supervised clustering method, and fuzzy discriminant analysis, a robust supervised method, have been successfully applied for characterization and classification of 72 solvents according to the chemical parameters (P’ and x(i)) developed by Snyder. The obtained results (fuzzy partitions) and parameters of the prototypes (robust fuzzy means) clearly demonstrated the efficiency and information power of the advanced fuzzy methods in solvent characterization and classification, and allow a rationale choice of a good solvent or an efficient mixture of solvents in chromatography and other fields. Also, this methodology generates the premises for future investigations using other different properties of solvents.

A zigzag-type quinone performs better than an armchair-type quinone in the reduction of nitrobenzene. When different kinds of functionalities co-exist, the reaction is dominated by the most active sites, but the most negative sites should also be taken into consideration if the acitive sites have zigzag structures.

Fe3O4 nanoparticles (NPs) with a face-centered cubic (fcc) structure and two different morphologies (nanospheres and nanoprisms) were synthesized by a facile one-step method. The synthesized Fe3O4 nanospheres and nanoprisms were monocrystalline and separable in a magnetic field. In different volume ratios of oleylamine (OAm) to dibenzyl ether, the sizes of the prepared Fe3O4 NPs ranged from 5 to 21 nm. The OAm amount in the synthesis can significantly control the morphology of Fe3O4 NPs. As the OAm content increased from 10 ml to 30 ml, the faceted nanoprisms shrank while the nanospheres enlarged. At an OAm content of 25 ml, the nanoprisms diminished while more hexagonal and sphere-like particles appeared, implying a critical point of morphology transition from triangle to hexagon. The magnetic properties also depended on the NP morphology and size. The prepared Fe3O4 NPs are promising candidates in medical applications such as magnetic resonance imaging, targeted drug delivery, blood purification, and tumor hyperthermia.

The study was aimed to evaluate the ability of native lichen Xanthoria (X.) parietina to biomonitor and bioaccumulate some heavy metals (As, Cd, Co, Cr, Ni, Pb), PAHs, PCDDs, PCDFs, PCBs and PBDEs and to evaluate the use of the native X. parietina as a multi-tracer tool for scenarios characterized by different anthropogenic pressures. Samples of native X. parietina were collected in six different sites (two green, two residential and two industrial areas, respectively) and analyzed for the target compounds. The results show that X. parietina was a useful tool for the biomonitoring of air quality in the selected areas, and was able to bioaccumulate all the studied metals and POPs. In particular, the total concentrations dry weight (dw) ranged between 8.1 and 103.4 mg kg(-1) for metals, from 113 x 10(3) to 183 x 10(3) ng kg(-1) for PAHs, from 868 to 7685 ng kg(-1) for PCBs, from 14.3 to 113.8 ng kg(-1) for PCDDs/Fs (Sigma TEq = 0.9-7.1), and from 194 to 554 ng kg(-1) for PBDEs. Besides, in general, the levels of analytes recovered in the different samples of lichen show an increasing trend from green to industrial sites, especially for PCBs (mean values equal to 1218, 4253 and 7192 ng kg(-1) respectively for green, residential and industrial areas). The statistical approach, based on Pearson’s correlation and principal component analysis tests, showed that one of the industrial sites was well-separated from the others, that resulted grouped due to some similarities.

Benzyl alcohol is a versatile reaction medium for the synthesis of different types of nanoparticles. Its ability to act as an oxygen source gave access to metal oxide nanoparticles, while its reducing properties can be harnessed for the preparation of metals. Here we report the synthesis of Pd and PdCu nanoparticles in benzyl alcohol supplemented by a detailed mechanistic study for both systems. To elucidate the chemical formation mechanism of the Pd nanoparticles, we performed in situ attenuated total reflection ultraviolet-visible (ATR-UV-vis) and Fourier transform infrared spectroscopy (ATR-FTIR), providing information on the organic as well as on the inorganic side of the reaction. Potential gaseous products were analyzed by in situ gas chromatography (GC) and mass spectrometry (MS). We observed the formation of benzaldehyde, toluene, and dibenzyl ether as the three main organic products. The formation of the PdCu alloy nanoparticles was studied by ex situ powder X-ray diffraction (PXRD). A time-resolved study of the synthesis at 100 degrees C indicated that initially three types of particles formed, composed of an alloy with high Pd content, an alloy with high content of copper, and palladium particles, and only later in the reaction course they transformed into an alloy with a Pd-to-Cu ratio close to 1.

Today, using new energy storage systems for peak shaving and load leveling with the approach of maximizing the efficiency of energy systems is inevitable. In the present study, a cogeneration integrated structure of power and cooling using liquefied natural gas regasification and solar collectors is developed and analyzed. In this regard, the purposes can be achieved by producing liquid air at an off-peak time and storing it as a cryogenic energy storage system and recovering it on-peak time. This new integrated structure generates 11.66 MW power and 4.502 MW cooling at the on-peak time. A Kalina-based combined cooling and power cycle and a gas turbine power generation unit are used to generate power from liquid air. Phase change material is used to store the heat from the compressed air entering the liquefaction stage (at the off-peak time) and recovering it at the on-peak time as the heat source of the Kalina cycle. Also, the solar parabolic trough collector provided with Zahedan climatic conditions the heat required for the direct expansion section. The electrical storage, round-trip, energy storage, and exergy efficiencies of the proposed energy storage system are 57.62%, 45.44%, 79.87%, and 40.17%, respectively. The most exergy destruction belongs to the heat exchangers section, which accounts for 50.85% of the total exergy destruction. One of the important results of the parametric study is the increase of round-trip and electrical storage efficiencies up to 47.59% and 61.60%, respectively, by minimizing the pressure of the inlet air to the liquefaction stage while maximizing the pressure of the liquid air inlet to the power generation stage.

Lignin is constructed from methoxylated phenylpropanoid with plenty of hydroxys and methoxys. Its conversion to valuable products is extremely attractive but especially challenging without additional hydrogen sources. Herein we report a hydrogen-free production of 4-alkylphenols directly from native lignin via self-reforming-driven depolymerization and hydrogenolysis over Pt/NiAl2O4. This is the first example of acquiring 4-alkylphenols from native lignin. Using this strategy, high yields of 4-alkylphenols, 17.3 wt %, were obtained from birch lignin. Reaction pathway and mechanism studies revealed that this strategy initiates from the reforming of aliphatic hydroxys, followed by the cleavage of C-O linkages, and ends via demethoxylation over Pt/NiAl2O4. Moreover, the subsequent aqueous phase reforming of the as-formed methanol accelerates the whole process. This strategy realizes the one-pot production of 4-alkylphenols from lignin by fully utilizing the structural hydrogen in lignin and H2O, providing a low-cost and safe method of lignin valorization.

Purpose: To describe factors (demographics and clinical characteristics) that predict patients who are at an increased risk of adverse events or unplanned return visits to a health-care facility following discharge direct to home (DDH) from intensive care units (ICUs). Methods: Prospective cohort study of all adult patients who survived their stay in our medical-surgical-trauma ICU between February 2016 and 2017 and were discharged directly home. Patients were followed for 8 weeks postdischarge. Univariable and multivariable logistic regression analyses were performed to identify factors associated with adverse events or unplanned return visits to a health-care facility following DDH from ICU. Results: A total of 129 DDH patients were enrolled and completed the 8-week follow-up. We identified 39 unplanned return visits (URVs). There was 0% mortality at 8 weeks postdischarge. Eight potential predictors of hospital URVs (P< .2) were identified in the univariable analysis: prior substance abuse (odds ratio [OR] of URV of 2.50 [95% confidence interval: 1.08-5.80], hepatitis (OR: 6.92 [1.68-28.48]), sepsis (OR: 11.03 [1.19-102.29]), admission nine equivalents of nursing manpower score (NEMS) <24 (OR: 2.28 [1.03-5.04], no fixed address (OR: 22.9 [1.2-437.3]), ICU length of stay (LOS) <2 days (OR: 2.95 [1.28-6.78]), home discharge within London, Ontario (OR: 2.44 [1.00-5.92]), and left against medical advice (AMA; OR: 6.06 [2.04-17.98]). Conclusions: Our study identified 8 covariates that were potential predictors of URV: prior substance abuse, hepatitis, sepsis, admission NEMS <24, no fixed address, ICU LOS <2 days, home discharge within London, Ontario, and left AMA. The practice of direct discharges home from the ICU would benefit from adequately powered multicenter study in order to construct a clinical prediction model (that would require further testing and validation).

Analyzing of tumor markers has become an important means for cancer diagnosis and prevention. In this study, a novel solid phase extraction based on porous magnetic cyclodextrin polymer (MA-CD) was developed and used for detection of trace small molecule gastric tumor markers in urine samples. The adsorption properties of the magnetic cyclodextrin polymer were tested. Through experiments of the solid phase extraction (SPE) at the different condition, the optimal condition was selected to test the two tumor markers by High-performance liquid chromatography -Diode array detector (HPLC-DAD). The analytical performance of the method showed good accuracy (88.82%-104.34%) and precision (< 3.55%), appropriated detection limits (1.016 and 5.714 mu g L-1) and linear ranges (0.6-24.0 mu g L-1) with convenient determination coefficients (> 0.9994). The results demonstrated that the developed approach is efficient, low-cost for gastric tumor markers detection.
