Effective remediation of cadmium and zinc co-contaminated soil by electrokinetic-permeable reactive barrier with a pretreatment of complexing agent and microorganism

The combination of electrokinetic-permeable reactive barrier (EK-PRB) is considered as a promising technology for the remediation of heavy metal contaminated soils. In this study, considering the convenient operation and recycling, a new sheet PRB material of sodium alginate/polyvinyl alcohol/attapulgite was prepared and characterized using scanning electron microscopy, X-ray diffraction and fourier transform infrared spectra. Subsequently, the effect of a pretreatment of citric acid (CA) and Shewanella oneidensis (MR-1) on zinc (Zn (II)) and cadmium (Cd (II)) removal from soils by EK-PRB was investigated. Results showed that Zn (II) and Cd (II) gradually migrated from anode to cathode in electric field within 8 days’ EK-PRB remediation. The simultaneous addition of CA and MR-1 resulted into the highest electric current, the lowest pH and the more negative soil zeta potential. Correspondingly, the highest removal efficiency of Zn (II) and Cd (II) also occurred in CA + MR-1 group. The new sheet PRB material effectively captured Zn (II) and Cd (II) from soils, and the most adsorption occurred in CA + MR-1 group: 1108.36 mg/kg Zn (II) and 53.84 mg/kg Cd (II) nearby the cathode after 8 days’ remediation. Specifically, for both Zn (II) and Cd (II), the CA + MR-1 group showed the greatest reduction in exchangeable and carbonate fractions and the highest increase in Fe-Mn oxidation and residual fractions. Overall, with a pretreatment of CA and MR-1, the residual Zn (II) and Cd (II) in soils were greatly reduced after EK-PRB remediation, due to the migration in the electric filed and the adsorption of the new sheet PRB material.

Joint Effect of Alcohol Drinking and Environmental Cadmium Exposure on Hypertension in Korean Adults: Analysis of Data from the Korea National Health and Nutrition Examination Survey, 2008 to 2013

Background Hypertension is a common disease found in 1.13 billion adults worldwide. Several animal studies have provided evidence of the joint effect of alcohol drinking and cadmium exposure on hypertension. However, no epidemiologic study has examined the association between these 2 risk factors and hypertension. Therefore, we examined the individual effects of alcohol drinking and cadmium and the joint effect of their coexposure on hypertension in the general population. Methods We analyzed data from 8,403 South Korean adults who had been randomly assigned to the Korea National Health and Nutrition Examination Survey from 2008 to 2013. Multiple linear and logistic regression analyses were conducted to estimate the association of alcohol drinking and blood cadmium concentration with blood pressure and the odds ratio (OR) for hypertension. Results The weighted prevalence of hypertension and high-risk drinking was 25.7 and 13.6%, respectively. The weighted geometric mean of blood cadmium levels was 0.94 mu g/L (95% confidence interval [CI]: 0.93 to 0.96). After adjusting for demographic characteristics, anthropometric measurements, health-related behaviors, and dietary and disease variables, the OR for hypertension in the group with the high-risk alcohol drinking was 1.67 (95% CI: 1.34 to 2.06) compared with the group without high-risk alcohol drinking. When the highest and the lowest blood cadmium quartiles were compared, the OR for hypertension was 1.46 (95% CI: 1.15 to 1.86). The positive joint effect of high-risk drinking and blood cadmium levels was statistically significant for systolic blood pressure (SBP; p = 0.037) and diastolic blood pressure (DBP; p < 0.001). Conclusions Our results show that heavy alcohol drinking had a joint effect with cadmium exposure to increase the risk of hypertension. Future efforts are needed to reduce alcohol drinking and environmental cadmium exposure to prevent hypertension in the general population.

Evaluation of the inhibitory activity of essential oils against spoilage yeasts and their potential application in yogurt

Yeasts are the leading cause of spoilage in yogurt. Considering the high demand from consumers to use natural products as an alternative to additives, essential oils (EOs) could be a promising solution to guarantee high microbiological standards. The present study highlighted the in vitro antifungal potential of cinnamon, ginger, lemongrass, mandarin, orange, lemon and lime EOs against spoilage yeasts isolated from yogurts prepared with pasteurized buffalo milk. A total of 74 isolates represented by 14 different species of Candida, Rhodotorula, Debaryomyces, Kluyveromyces and Yarrowia genera were subjected to a disc diffusion assay, showing lemongrass EO to have the highest antifungal activity (40.97 +/- 9.86 mm), followed by cinnamon (38.46 +/- 6.59 mm) and orange (12.00 +/- 4.52 mm) EOs. Yarrowia lipolytica was less susceptible to lemongrass EO than Candida sake and Yarrowia deformans isolates. Ginger EO exhibited the lowest efficacy. A minimum inhibitory concentration (MIC) assay showed the ability of lemongrass and cinnamon EOs to inhibit the growth of all selected isolates at concentrations between <= 0.31 and 1.25 mu L/mL. Therefore, for the first time, the two best-performing EOs (lemongrass and cinnamon) based on in vitro assays were assessed for their potential roles as preservatives in an in vivo yogurt model prepared at the laboratory scale. Since some limitations, such as the inhibition of lactic acid bacteria by cinnamon EO, consequently leading to fermentation failure as well as species-specific antifungal activity of lemongrass EO, were observed, further studies are needed to explore the possibility of using a slightly higher concentration of lemongrass EO and/or combinations of different EOs and/or their components. Finally, since yogurt spoilage could also be prevented by correct sanitation procedures of the production environment, the sanitizers commonly used in the food industry were tested against all isolates, showing the high efficiency of alcohol-based sanitizers and the ineffectiveness of chlorine-based sanitizers.

Volatile compounds sorption during the aging of Chinese Liquor (Baijiu) using Pottery Powder

Pottery jar is the preferred storage vessel for aging baijiu, Chinese liquor, and it could sorb liquor micro-compounds. The objective of this work was to identify the sorption of liquor micro-compounds onto pottery powder, and gained insights regarding the sorption processes and mechanism. The sorption of liquor micro-compounds onto pottery powder of different sizes was studied using different kinetic models. The results showed that the sorption capacity varied among particle size of pottery powder, which also affected equilibrium time. The sorption process could be well described by the pseudo-second-order model, and the external diffusion was the rate-limiting step. Liquor volatiles in pottery powder at equilibrium were characterized, which detected alcohols, esters, acids, and furan by gas chromatography-mass spectrometry (GC-MS). These findings demonstrated pottery could not only cause subtractive changes that occur to liquor during the aging period, but also as a vector for transferring aromas sorbed when reused.

Autoignition characterization of methanol, ethanol, propanol, and butanol over a wide range of operating conditions in LTC/HCCI

In this work, the autoignition properties of methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol, and sec-butanol are studied in HCCI and compared. Experiments were performed, characterizing the sensitivity of these fuels to equivalence ratio, intake temperature, residual fraction, intake pressure, and engine speed. Under all of the low boost pressure operating conditions considered (1.15 bar), the order of reactivity of each fuel from low to high is: isopropanol, sec-butanol, ethanol approximate to n-propanol approximate to isobutanol, methanol, n-butanol. n-butanol was less sensitive to changes in intake temperature than the other six fuels at low boost conditions. The required intake temperature to maintain a constant combustion phasing decreased significantly for n-butanol with intake pressure due to emergent intermediate temperature heat release (ITHR). At an intake pressure of 1.95 bar, secbutanol showed some amount of ITHR which decreased its sensitivity to intake temperature. However, secbutanol still maintained its high autoignition resistance, unlike n-butanol. Isobutanol did not show any ITHR at this intake temperature, though did show a decrease in intake temperature sensitivity. With the exception of n-butanol, the behavior and sensitivity of each alcohol fuel to the wide array of operating conditions considered were similar, with small differences in autoignition resistance. This means that these six fuels could potentially be blended and used interchangeably with little change to their autoignition characteristics.

Construction of hierarchical photocatalysts by growing ZnIn2S4 nanosheets on Prussian blue analogue-derived bimetallic sulfides for solar co-production of H-2 and organic chemicals

Exploring highly efficient bifunctional photocatalysts for simultaneous H-2 evolution and organic chemical production in pure water represents a green route for sustainable solar energy storage and conversion. Herein, a facile strategy was explored for preparing a hierarchical porous heterostructure of Fe4Ni5S8@ZnIn2S4(FNS@ZIS) by the in situ growth of ZIS nanosheets on Prussian blue analogue (PBA)-derived bimetallic FNS sulfides. A series of FNS@ZIS hierarchical structures were facilely prepared by adjusting the loading amount (n%) of FNS (n = 19, 26, and 32 for FNS@ZIS-1-3). These structures can efficiently drive the solar co-production of H2 and organic chemicals. The optimal co-production was achieved with FNS@ZIS-2, affording a H-2 evolution rate of 10465 mu mol.g(-1).h(-1), along with high selectivity for the oxidation of benzyl alcohol to benzaldehyde (>99.9%). The performance was 22 and 31 times higher than that of FNS and ZIS, respectively, and even superior to the state-of-the-art results achieved using various sacrificial agents. Further mechanistic study indicated that the unique hierarchical core/shell architecture can facilitate interfacial charge separation, afford bimetallic synergy, abundant active sites and excellent photostability. This work highlights a simple and efficient method for preparing porous multimetallic hierarchical structures for the solar co-production of organic chemicals and H-2 fuel.

MOF-derived well-structured bimetallic catalyst for highly selective conversion of furfural

Selective conversion of furfural can produce some important chemical intermediates. However, it is a challenge to design suitable catalysts due to the complex reaction route. A series highly dispersed Co-Ni alloy NPs embedded in porous nitrogen-containing carbon matrix multifunctional catalysts (xCo-yNi@NC) were prepared by pyrolysis of MOF template. The characterization results showed that Co-Ni alloy presented strong bimetallic synergistic effect and introduction of N species influenced the physicochemical properties of the catalyst, hence promoted the catalytic performance. Moreover, Lewis acid sites provided by metal oxide species can polarize the C=O bond via lone pair electrons on the oxygen atom, which contribute to furfuryl alcohol formation and accelerate furfuryl alcohol rearrangement to 4-hydroxy-2-cycloentenone. In addition, the solvent played an important role in the product distribution. Under the optimized reaction conditions, 99.0% furfuryl alcohol yield was obtained in methanol solvent, while 92.5% cyclopentanone yield was obtained in water solvent over 2Co-1Ni@NC.

Acute effects of alcohol on resting-state functional connectivity in healthy young men

Alcohol abuse and dependence remain significant public health issues, and yet the brain circuits that are involved in the rewarding effects of alcohol are poorly understood. One promising way to study the effects of alcohol on neural activity is to examine its effects on functional connectivity between brain areas involved in reward and other functions. Here, we compared the effects of two doses of alcohol (0.4 and 0.8 g/kg) to placebo on restingstate functional connectivity in brain circuits related to reward in 19 healthy young men without histories of alcohol problems. The higher, but not the lower, dose of alcohol, significantly increased connectivity from reward-related regions to sensory and motor cortex, and between seeds associated with cognitive control. Contrary to expectation, alcohol did not significantly change connectivity for the ventral striatum at either dose. These findings reveal unrecognized effects of alcohol on connectivity from reward-related regions to visual and sensory cortical areas.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4461-39-6, in my other articles.

Tribological Rehydration and Its Role on Frictional Behavior of PVA/GO Hydrogels for Cartilage Replacement Under Migrating and Stationary Contact Conditions

Graphene oxide (GO) was incorporated into polyvinyl alcohol (PVA) hydrogel to improve its mechanical and tribological performances for potential articular cartilage replacement application. The compressive mechanical properties, creep resistance, and dynamic mechanical properties of PVA/GO hydrogels with varied GO content were studied. The frictional behavior of PVA/GO hydrogels under stationary and migrating contact configurations during reciprocal and unidirectional sliding movements were investigated. The effects of load, sliding speed, diameter of counterface, and counterface materials on the frictional coefficient of PVA/GO hydrogels were discussed. PVA/0.10wt%GO hydrogel show higher compressive modulus and creep resistance, but moderate friction coefficient. The friction coefficient of PVA/GO hydrogel under stationary and migratory contact configurations greatly depends on interstitial fluid pressurization and tribological rehydration. The friction behavior of PVA/GO hydrogels shows load, speed, and counterface diameter dependence similar to those observed in natural articular cartilage. A low friction coefficient (similar to 0.03) was obtained from PVA/0.10wt%GO hydrogel natural cartilage counter pair. [GRAPHICS] .
